Dear Sir:
In a verbal reply to our letter of August 15, 1958 you
requested that we provide you with some detailed information on the
modifications made to the various machines which comprise your two
Minicard installations, as well as the additional equipments Which
are being supplied to you but which are not called out in our contract.
We are appending the requested information to this letter
and have so arranged it that the changes are identifiable with individual
Minicard machines, The lists which are submitted were prepared by
our engineers and constitute what in their opinions are the conceptual,
functional and manufacturing changes which were made to improve machine
capability, safety, and performance. While the lists are not intended
to be all-inclusive, we believe that they include the more significant
changes made to the machines. The brevity of the text associated with
each of the changes should in no manner be construed as indicative of the
magnitude of the work involved in them, since our people have condensed
the information to reduce the volume of written material.
, Our letter of August 15, 1958 made mention of the fact
that we had installed and were currently operating a Minicard system
in the Pentagon. That system was installed in April of this year,
and from that time to the present a number of machine modifications
have been made. As we have previously informed you, we have con-
tinuously up-dated the machines in your two sets to incorporate
such changes, and as of this date we are in the process of completing
that work. As an additional enclosure to this letter we are includ-
ing the listing and description of the machine changes which have
taken place since April of this year, the last of which are currently
being made on your machines.
We trust that the enclosed material fulfills your request.
Very truly yours,

1. FILM LUBRICATOR
ENCLOSURE I
-51
Since most of the Minicard machines are called upon to extract,
handle, and read one Minicard record at a time, it is important to insure
that the cards are extracted one at a time from magazines. If cards are
extracted in multiples, they cannot be read by the electronic scanning
equipment, and further may cause a malfunction of the card transport
mechanism. To mitigate against the occurrence of these error producing
phenomena a film lubricator was developed that would permit the coating
of the film with a lubricant to prevent cards from sticking together. The
Lubricator is a motor driven device which is used to coat both sides of the
film after processing and also provides for appropriate rewind of the film
so that its orientation is proper for subsequent handling.
2. MASK PRINTER
A study of the tolerances which affected the position of the
filing word code on the Minicard records showed that it would not be possible
to use a camera code target to expose a mask for the file word area on the
Minicard record. A special device called the Mask Printer was so designed
that it would accurately expose a mask of appropriate dimensions on the
Minicard film at a high rate of speed. The device is used for film raw
stock which is to be exposed in the camera to prepare 1N Minicard records.
3. MULTIPLE STICK
A device capable of removing cards from ten magazines simultane-
ously was designed and built. In essence, it consists of ten regular
2000-card sticks with a common handle which actuates all sticks at once.
I. HOLDER FOR MULTIPLE STICK
Appropriate brackets have been attached to the sorter to hold
the multiple stick in between operations.
S. BLOCK STAND
A stand was made to hold a pair of 50-magazine blocks. It is
so design ,d that the blocks can be transported on it between the file
cabinets and the Sorter and Selector.
6. INCLINif.D BLOCK STAND
A special stand was made to hold one 50-magazine block at a
45? angle to permit examination of the bottom of the block in case of
trouble.
-2-
7. TRANSIENT CARD HOLDER
This is a 10-compartment device into which sticks of cards
can be inserted for temporary storage in between successive machine
operations.
8. CODE READING LOUPE
This loupe is a spccially designed device with a five power eye
piece, a reticle, and a Minicard film record holder. When the reticle is
in contact with the card the reticle pattern enables the viewer to read the
code and readily identify code errors that may exist.
9. TRANSFER TRAY SPACERS
Two extra spacers were provided for each transfer tray to speed
up the combining of groups of cards onto one stick.
10. MULTIPLE TRANSFER TRAY
A special transfer tray with six compartments is being made.
This device will serve many work organization needs and may be used as a
transport medium for several sticks of cards, as a temporary storage place
for long sticks of cards, and as a transfer medium for complex regrouping
or combination jobs.
At the inception of the contract the Minicard Camera design
was completed and a model had been constructed. Although the Camera
operated satisfactorily, it was decided to institute a redesign in order to
improve the operational features of the machine. In the original model .41.e
electrical controls for the Camera were housed in a separate cabinet. It
was thought desirable to incorporate these controls in the main Camera
body. The self-perforating feature was al s) eliminated so that pre-perforated,
film could be used. In addition to these major conceptual changes the
following list covers many of the detailed modifications made to the re-
designed instrument.

In the first conversations which were held between your
representative and ours it was planned that the original Minicard Document
Camera would be used to fulfill the aerial photography requirements. Since
it was intended that the work to be performed by this Camera would be
consistent with the state of machine development at that time, no further
extension of design work was thought to be required. Discussions subsequent
to the start of work indicated that a much more elaborate machine was wanted,
and that it would of necessity be required to possess higher quality images
and a magnification different from that supplied by the Document Camera.
The net result of that decision was to require that an entirely new approach
be taken to the design of a camera which could record, with a minimal loss
- 6 -
of resolution, aerial photographs of extremely high quality. All prior
design work was set aside and a compretely new engineering approach under-
taken. An attempt was made to capitalize on the engineering changes
initiated for the new Document Camera so as to avoid duplication of effort,
and many of the changes which were made on the Document Camera mechanism
design were also reflected in the design of the mechanism of the Aerial Photo
Camera.
In addition to these modifications, there is listed below the
major additional work that was performed in the execution of this design.
a
As may well be appreciated, an enormous amount of photographic
investigative work was undertaken in collaboration with the customer's
technical personnel in order to arrive at'a suitable method for transferring
original aerial photography to Minicard film without loss, of photographic
latitude. The same kind of effort was expended for the other cameras and
resulted in many machine modifications, some of which are covered in the lists.
1. Code target pins replaced - aperture mask reworked to comply with
Minicard tolerances.
2. Added baffle and exhaust system to drive motor to eliminate oil vapors.
3. Added a blower cut-out to condenser illumination lamp to shut off
blower in event of lamp failure (to prevent breakage of optics from
rapid cooling).
4. Added perforated paper tape reader to speed camera code recording and
permit use of fixed field tape loop.
5. Altered camera circuitry so that camera will verify the first line of
code from the tape reader as well as the Flexowriter.
6. Variable exposure lamp control and meter installed. Meter replaced
later with more sensitive exposure indicating device to improve
quality.
7. Torque motors installed to improve code positioning accuracy.
8. Cam control for torque motor capacitance added to footage dial.
9. Added code target lamp adjustment. This required alterations to
camera structure to provide lamp adjustment capabilities.
ID. Changed code column format to eliminate CS - CF sortation column.
11. Reworked film idlers to improve film handling.
12. Rebuilt sensing arms on lens shaft for reliability (mechanical
yuggedizing of arms to improve stability).
13. Mercury lamp for negative illumination changed to tungsten filament
lamp with filter.
- 7 -
14. Added power supply to operate film punch solenoids.
15. Remotely mounted the vacuum pump to eliminate vibrations.
16. Designed and built a new recording lens since existing commercial
lenses were unsatisfactory.
17. Designed a photoraphic objective for P-2 Camera which Was later
suspended.
18. Conducted a proeram of photographic investigation to determine proper
exposure judging system for recording of photo aerial negatives on
Minicard film records.
19. Program controls for code recording changed as a result of format
change requirements.
20.- Relocated code target for 8.000X to 8.2991 reduction to accommodate
43rd bit format change.
21. Developed and installed a.special mechanism to shift lens from aerial
photo to code recording state while holding positional tolerance to
less than .0002" total variation.
FILM PROCESSOR
As may be appreciated, an entirely new film and film processing
technique was required in order to insure the successful performance of the
Minicard system through its many generations. Many changes were made to the
film and the emulsion and were immediately followed by concomitant changes in
the chemistry of the process. Invariably, these changes to the chemistry
required changes to the machine. Some of the more significant machine
changes which were instigated after the machines were built and the subsequent
1 chemistry of the process was established are summarized in succeeding para-
graphs.
1. Several methods were tried to control the developer temperature.
a. A heater end thermoswitch were first used. The adjustment was too
course for this purpose, but is now used for holding the processor
in a stand-by condition.
b. A recirculating system was added consisting of a circulating pump,
a jet-pipe in the eeveloper, a thermistor probe controlled by a
Fenwal electronic unit, and a heat exchanger controlled by a Sarco
valve.
The Sarco valve control was too course and was later replaced by
a solenoid valve. At the same time the temperature of the incoming
water to the heat exchanger was controlled.
Two air Squeegees were added; one after the developer tank to mitigate
against uneven development, and the other after the squeegee rollers
to eliminate drying spots.
The direction of the take-up spool was- changed to wind the film with
the emulsion out in order, to produce flatter cards. Provisions were
made for a simple change to permit spooling with emulsion,outor.in.
A study of the effect of drying temperature on film curl resulted in
reducing the drying temperature to 135?F.
Several modifications were made to prevent dust and lint from accumulat-
ing on the film during processing.
a. A cover was added over the take-up reels.
b. The blower housings were cadmium plated.
c. Holes, which were put in the back doors to increase ventilatIons
were covered with filters.
A clip was added to hold the squeegee rollers together even after a
film splice has passed _through.
The controls were rewired to make it impossible to process film with
the switch in the stand-by position.
The terminal strip in the rear of the machine was repositioned to
prevent short-circuiting when it was splashed by solutions dripping
from the replenishcr lines.
A hinged plexiglass cover was added to keep the film area clean during
cutting and idle times.
Eccentric stop posts were installed to keep sprocket clamps from making
contact with sprockets when the cutter is run without film.
Clearance in the film guides was cut down to help keep concave or
convex film in a flat condition, enabling it to pass under the
cutting
die without marking.
Because of the above change, the nylon pressure pad was removed to
eliminate a source of marking and adding static to cards.
The bottoms of the cutting head assembly castings were scraped to allow
a more accurate reassembly after service work.
I
- 9 -
CUTTER (cont.)
6. Edge notch sensing micro switches were chanted to a short-throw type
to help overcome close tolerances in camera and inspection viewer edge
notching.
7. A new Venturi-type adapter was added for a much smoother air flow,
increasing the suction at the cutting areas.
8. Drive belts used on the reject roller assembly were changed from plastic
to spring type, to minimize breakage.
-
9. The cutting die (1.260) dimension was increased to positive side of
perforation pitch tolerance to eliminate possibility of cutting cards
at both ends during cut-off operation.
10. A scrap elimination assembly was added to dispose of reject cards and
film.
U. The lead-in taper on the cutter stick was changed to prevent jamming;
this required new sticks.
12. Weights on sticks were changed to help prevent jamming.
13. A safety switch was added on the magazine assembly to shut off the
machine after a 2000-card stick was full.
14. The intermittent sprocket was replaced with a sprocket with a new type
tooth to eliminate slippage. The new sprocket was made of steel instead
of aluminum to decrease wear.
15. A jumper cable was made to allow running of the cutter for service work
with the outer case removed.
INSPECTION VIEWER
1. An adjustable friction brake was added to the rewind spindles to
prevent coasting.
2. A 2-power magnifying glass was added to aid in examination of the film.
3. After ayme experience with the original design, it became apparent
that the tilted film track was more elaborate than was required.
Therefore, the entire viewer was redesigned and simplified.
a. The light box was vide with a flat top.
b. The film is supported by rollers at each end; the track is
eliminated.
c. The rewind assemblies were greatly simplified.
-10-
INSPECTION VIEWER (cont.)
d. The punch was redesigned.
e. Opal glass was added for diffusing the light.
h. After some experience was gained with the new viewer; it was foUnd
desirable to cut a .015 recess in the punch block to reduce the
possibility of scratching film as it was passed by the station.
DOCUMENT ANALYSIS VIEWER
1. A request was made_that_the original model of the viewer with a
transmission screen) be reworked as follows:
a. Change magnification from 50X to 60X.
b. Change screen size from 8" x 11" to al" x 14".
2. It was requested that a second model be made, this one having a
reflection screen. (All other components were duplicates Of those
in the first model.)
3. Image rotation was requeSted. Several methods were tried. The dove
prism method was selected.
h. Reversibility of feed was required (i.e. movement of a Minicard record
from any magazine to any other magazine). This complicated the trans-
port and vacuum system.
5. The housing at the side of the
to the screen.
6. It was requested that the angle
be changed from 55? to 15? with
screen was made movable to permit access
of the reflection screen, in the model,
the horizontal.
7. It was further requested thi,t the angle of the reflection screen in the
model be changed from 15? to 25? with the horizontal.
8. Scan control was added. Rotation of an 8" x 14" image 90? resulted
in the 14" dimension being across a 81" wide screen, thus cutting off
each end.
9. A phasing switch in the image control assembly was installed to prevent
the possibility of inadvertently switching the vacuum off the platen as
a result of using the scan control.
10. It was necessary to add a stop pin to the image control assembly to
prevent counter-clockvise rotation of the image control knob beyond the
numlYr one position when scanning.
-11-
11. The viewer was redesigned to be integral with its own desk.
12. The screen tilt was made variable between 25? and 40? with the
horizontal.
13. The vacuum control system was modified to provide electrical interlocks
and fool proofing. The original design used manual control of the
vacuum.
14. A method for image selection or identification (punching)was added
after the design had been completed.
15. The lips were changed from the sides to the ends of the magazines so
that the transport plate could be used as the die during punching.
16. Because of the above change it was necessary to eliminate five rows
of vacuum holes - -two rows across one end of the transport plate and
three rows across the other - -to prevent vacuum loss when removing a
card from a magazine.
17. The space between the magazine lips was increased to assist in re-
venting vacuum loss when removing a card from a magazine.
18. Two adjustable points or tips were added to the lower end of each
magazine to riffle or separate cards at time of withdrawal.
19. Vibrations caused by the vacuum pump and blower produced a deleterious
effect on image qurlity and so the shock mount design was completely
changed.
20. Several changes were made to the lens to improve image quality. The
change which provided the greatest improvement was that of limiting
the aperture to f/3.5. ?
21. A power relay was installed to shunt the main switch. This, in effect,
made the main switch inoperative while a card was being held by v acuum.
22. A terminal block was added to the inside of the front panel. This
allowed the front panel to be removed, thereby providing greater
accessibility to the viewer interior.
23. It was desirable to reduce the noise level at the viewing position
caused by the vacuum punp exhausting inside the viewer. An elbow and
length of pipe were added to the pump to carry the exhaust down to the
floor through an opening in the bottom of the viewer.
24. Trays were added beneath the magazines and viewing station of the
instrument to prevent card loss due to power failure.
25. It was necessary to add a second mark-button wired in series with the
first one to prevent an operator from holding the transport knob while
punching.

DOCUMENT ANALYSIS VIStLft (cont.)
26. The original punches produced holes with barely perceptible. ragged
edges and as they became More worn the edges of the holes became
slightly more ragged. The ragged edges of the holes were sometimes
interpreted by the Enlarger to be document control Marks. The punches
were reworked to fit better and produce sharper edges. Alignment of
the punches and dies, was not satisfactory with the existing design and
the punch life became very short. Since regrinding and replacement
were difficult, the whole assembly was completely redesigned.

DUPLICATOR
The mechanical portion of the Minicard Duplicator was substantially
completed prior to the start of the contract. The machine had to be completely
revised as a result of the decision to provide for the handling of multiple
card documents. The original plans were limited to the provision for multiple
card document handling by means of a perforated tape input that would supply
the sortation information recorded on the Duplicators. Although a tape
operated Duplicator was planned and would have performed all of the desired
functions satisfactorily, it was felt because of the possibility of errors
being introduced through manual operations that the machine should be made
more wholly automatic. The final design was made automatic and uses electronic
storape for the file expansion operation. From a machine that was originally
intended to provide only contact prints and tape controlled cross-filing the
File 7xpansion Duplicator suddenly blossomed into a sophisticated data
processor for the Minicard system.
Some of the machine modifications which reflect the evolution of
the machine into its current state are given in succeeding paragraphs.
1. Decision made to input data from rirst card only of any document (Modes B)
rather than from two cards.

SELECTOR
It may be appreciated that the requirements of the Minicard
Selector depended rather closely on the specific indexing system used.
While the Selector could easily be adapted to any indexing system, the details
of its electrical circuits could not be settled until an upper limit was set
on the complexity of the indexing system.
-20-
SELECTOR (cont.)
Although the original Selector used a cross-bar switch memory
and static circuitry, we were unable to capitalize on the engineering work
performed on the first instrument since it was desired to go to an electronic
memory unit and dynamic control circuitry for this Selector.

higher level and the refinements in the circuitry introduced to reflect the
change. The capability of removing identical cards was added and the number
of selection magazines was increased to ten in order to permit fine sorting

MISCELLAN:OUS IT,i1S APPLICABLE TO SELECTOR, SORTER, AND DUPLICATOR (not includ
in other lists)
1. When the scanning system was first completely assembled, it was found th
there was insufficient electrical signal from the Ektron detectors due
to the fact that the cells were more infrared sensitive than had been
anticipated. A study was made of the spectral characteristics of all
of the elements in the optical system. As a result, new coatings were
developed for the reflective and transmission optical elements and some
mechanical and optical revisions in the scanner mechanisms were made.
2. Durin, development work on the scanning and code reading system, it
was realized that no provision was made f or redundancy checking to .
insure high code reading reliability. While it wAs not feasible to ad
the necessary circuitry to the equipment being built at the time, it
-26-
MISCELLANEOUS ITEMS APILIjaBLE It SeLe'd0R, SORTR, AND DUPLICATOR (cont.)
was felt prudent to change the card code format to include room for
a 43rd or parity check bit. This would allow later equipment to
accomplish an automatic redundancy check on the transfer of digital
information from the card to the logical circuitry. This format
change required a magnification and centering shift of all code target
and scanner optical systems.
3. The original Minicard code format called for exposing the masks for the
two sortation columns in the camera at the same time that the balance
of the code was recorded. The sortation data was to be subsequently
exposed in the duplicator in exact registry with the camera exposed
masks. In practice this placed intolerably tight tolerances on the
camera and duplicator mechanisms. The Minicard code format was there-
fore altered to permit substantially the same functions to be performed
but with practical tolerances. This change required the sacrifice of
a small amount of card coding capacity and introduced the separate
mask-printing operation on 1N raw stock previously described.
4. During the evaluation of the code reading system it became apparent
that the reading system was required to accommodate a rather large
number of combinations of mechanical, optical, photographic and
electronic variables. Consequently, an intensive-study was initiated .
of all the factors which could affect the accuracy of code reading.
As a result of this study ?a number of changes were made.
a. The code reader circuitry was ccmeletely redesigned to work on a
"signal differential" or "bit edge recognition" basis rather than
an absolute amplitude basis. This was necessary in order to
accommodate signals of varying amplitudes that would be produced
by residual variations in such features as card density, reading
station illumination, ambient temperature changes, etc.
b. The Ektron detector cell array was modified to reduce the width of
the active area, and a padding procedure was instituted in manufac-
ture to limit cell sensitivity variations.
c. In order to permit more accurate set-up, the scanner mechanism
was modified to permit adjustment and alignment as a unit and a
micrometer cell translation adjustment was added.
d. Mechanical and optical tolerances were determined for the Minicard
record itself and for cameras, duplicators and card scanning
stations.
In order to p,.ndt reesenable tolerances in the code reader electronic
circuitry, it was found necessary to guarantee certain minimum dimensions
for the marains surrounding the sortation columns on the ninicard records.
This required more longitudinA. scece for the sortation columns, but
it was not desirable to reduce the card code ceacity. It was therefore
decided to uliminete the seeni sertation column and uee the space
?

MISCLLANEOUS ITES AP:l,rABL,Z. TO .3-.Z.Li3TOR, SORTR, AND DUPLICATOR (cont.)
thereby gained for the first column margins. The card format was
accordingly changed.
6. In order to minimize the accident-a triggering of bit amplifiers due
to dust and other blemishes on the cards, certain timing mark blanking
circuitry was aated to the cede reader.
