appropriate length of aerial film and the devel;ping time are established~
for a developing apparatus with manual rewinding. A method is suggested
for cyclic development by-continuous winding of the film from one spool to
the other. It produces excellent results with regard to increasing the
photosensitivity of the film and the uniformity of development. A sonsito-~
metric~investigation is made, of a method of development which-increaaes
light-senaitivity and includes repeated stee ing of the film in the develop~r'lv..45
with subsequent holdingng between glasses. ~Abstracterls notes Complete f':

ABSTRACT: In the industrial manufacture of endless glass fibers the
regulation of temperature of the platinum-rhodium melting-
pots is performedby means of an electronic control-millivolt-
meter ofthe 3VW -47 type. The millivoltmeter controls the
autotransform,er of the AO& 10/0,5 lype by control mechanism
OR -1. The electric furnace in which the glass-melting pot
is installed shows constant heat balance at stable temperature
conditions. Any change of temperature of the pot in accom-
panied by a change of the power consumption. Thus, also
constant temperature of the electric furnace can be obtained
by stabilization of the supply voltage which is supplied to,
the terminals. NlIsteklovolokna, together with kafedra

and tested a contactless scheme of automatic stabilization
of the supply voltage of the furnace (Fig 1). In figure 2
the time course of voltage at the terminals is given. Auto-

A11STPUICT: A device is described which welds thermocouple wires together in a sodium
chloride solution., The wires, twisted together at one end, are cla=ed vertically to
a holder which can be moved toward the surface of the salt solution by meansof a
screw mechanism. One conductor of the power line (220 v a-c) is connected to the
holder mid anotherto the solution. When the wires make contact with the surface
!
t
:of the solution,an electric arc is created which welds the wires together. A special
iswitch cuts off -the power automatically. The welded function is cooled by dipping it
into the solution again.' Welding time must be established by testing the device
at a current insufticient for arc formation, The junction in smooth and the strength
of the wires is not significantly affected. Orig. art. has: 2 figuree.

efficient sleeper-padding machine for tampine the ballast
under the railroad sleepers during the construction and repair
of railways. The machine, a self-propelling mechanism moving
on rails, and driven by a water-cooledo 90 hp Internal com-
bustion.5-cylinder carburetor enginejha apacity of 200
sleepers per hour.' Its orking speed i: a5.130 kn/hr and its
transport speeds are 18 :nd 33 ka/hr. The total weight of the
machine in 10 tons. At presentq the Dnepropetr(wok Locomotive-
Plant in completing the manufacture of an experimental RR

TITLE: An.Instrument for the Measurement of Electrical Conductivity
and Hall's Constant in Thin Semi-conducting Layers.
(Pribor dlya izmereniya elektroprovodnosti i postoyannoy
kholla v tonkikh sloyakh poluprovodnikov)
PERIODICAL: Pribory i Teldinika Eksperimenta, 195?, no-5,
pp. 119-120 (USSR)..
'ABSTRACT: The instrument (Fig.1) can be used for rqid measurement of
.electrical conductivityand Hall's constant for given areas on
thin specimens deposited on slides of gla.3s or other dielectric
material. The slide 3 with the deposited samples 4 is kept in
position by the cam 2 on a moveable table 1. The table moves.,
on a lath along the guide 7. The fixer 5 keeps the table and,
consequently, also the sample in the required positions. A
panel 8 on a moveable table has current, compensation and Hall
electrodes 6 attached to it. This.panel is kept in place by
springs 13 and is,ipoved by means of the lever 9 and cam 10,
perpendicularly to the plane of the specimen, and keeps the
direction of motion by means of the four rods 12. The elec-
trodes can move freely along the bushes,.pressed into the panel,
under the action of bronze springs 11. The scheme produces the
(;ardl/3 necessary control of contact pressure on the specimen and the

i)anel can be raised when the table 1 carrying the.specimen is
moved. The simple construction of the electrodes means that one
can have a collection of electrodes made from different
materials and having contact surfaces of different form and
size, and that one can deposit on their surface various
coatings. When working with verythin layers one can put end
pieces of soft metal (e.g. indium or tin
on the ends of the electrodes to protect the layer. The
distance between the electrodes on the panel can be varied
depending on the size of the sample. The samples were deposited
on slides 23 x 80 mm in arga, the surface area of the samples
thems6lves being 23 x 50 mm---. After the deposition, the latter
surface i~ divided by means of a standard pattern into sections
23 x 4 mm. with gaps of 1 mmbetween them. The device is sus-
pended between the poles of an electromagnet on two pivots 14,
connecting the device with a platform placed on the windings
of the electromagnet. Provision is made for the control of the
position of the device between the poles of the electromagnet.
The device lies in a gap of 25 mm between the poles of the
electromagnet. Brass was used for the metallic pwts and organic
uard2/3glass for insulation. Measurements were carried out (Ref.1) of

the properties of thin layers ofseparate elements obtained by
evaporation,in a vacuum and also of thin layers of bina y speci-
mens obtained by Vekshinskiy's method (Ref.2) from elements of
~group III and V*of the periodic table. By a comparison of the
distribution of electrical properties along the length of a
specimen, and the distribution function of concentration of
the components calculated from Vekshinskiyls formulae, it is
possible to obtain the dependence of electric properties on
composition in a wide range of concentrations of the binary
alloy. Fig. 2 shows the results of measurements of specific
resistance of a thin layer of variable composition of indium-
antimony. There are 2 figures and 2 Slavic references.
