During the week of 9 Itveliber through 1, Joresber 195,
p to thellfactories for the purpose of
end testing various generator sots prior to their final
o the Agency.
2. Testing of the five 1003 ke. units that were procured from
25X1A5a1 the was initiated on the morning of 10 Novaber.
Four units were tested and accepted by 12 Wovember, but the fifth unit
would not respond electrically as specified. When inspection indicated.
that its voltage regulating -circuit was at fault, it was decided that
this unit should be serviced by $ qualified representative of the
5 1A5a1 Arrangements were thereupon made to send a
Wearied service man to Detroit within three days to adjust the difficulty.

3. In view of the feet that four of the generator sets were
completely acceptable and the fifth one mechanically satisfactory, 1
agreed to accept all of the units then, at the time of the inspection.
This agreement was made of course with the assurance by t the 25X1A5a1
electrical trouble would be corrected before the ship fifth unit.
I. Since er, return I have learned that the fifth generator set
has been repaired and tested satisfactorily. The entire shipment of
the five generators and their associated gear and spare parts left the
Detroit factory for the West Coast on 26 November 1958.
. I depsrted fres Detroit on 12 November and arrived at the
1A5a1 on 13 November 1958.
6. The prototype model of the 5 kw. generator set that the 25X1A5a1
5a1 had proposed and built for us was inspected and tested. The
modifications that we had requested had all been incorporated in the
unit and tested satisfactorily.
7. This new generator unit, which will be known as 25X1A5a1
WW-4-S is a very versatile generator set. Special provisions

have been made so that a 'variety of field applications can be obtained
by merely making a few sdjustments or changing a minor part. ?he units
when crated will contain an extra flexible exhaust extension and a most
efficient automotive type muffler for silencing. Also, a 3-way valve
has been installed which enables the selection of either a gravity fuel
feed or an underground tank. A special fuel p* with a lift of 15 ft.
can be utilised if so desired. Another excellent feature is the arrange-
ment of the electrical output connections which offers the use of a variety
of separately fused circuits. In addition to these features the unit in
skid mounted and completely weatherproof.
8. Vhile at the factory it was learned that 25X1A5a1
has developed a new type of generator that is completely SPAM YU* on
innovation which elimivates all radio interference that Cu the past has
been caused by arcing brushes. In desigaing this generator they have
completely eliminated the wearing parts such as the commutator, slip
rine*, brush holder assemblies and the brushes. There is no possibility
of sparking with these alternators. All components which might produce
electric arcing has been replaced with rectifier systems, resulting in
^ continuous uninterrupted current flow from the exciter to the AC output
stator lead wires. The exciter of the brushless alternator consists of
a revolving armature type AC generator. The 3-phase output of this exciter
is fed through a rotating silicon rectifier asseably mounted on the alter-
nator Shaft, the DC output of this assembly being then fed lig the revolv-
ing aitor field. The stationery exciter field poles are red from the
output of the alternator through a stationary rectifier assembly.
9. All in all., this type of alternator appears to be the solution
to many radio interference problems that have been occuring
in the field. With this in mind r approached with 25X1A5a1
the idea that they build up a unit to our specifications, following the
lines of the 5 kw. unit they are now perfecting for us. This they agreed
to do, if vs desired, on a cost-plus basis. Such an arrangement would
offer on excellent opportunity for the Agency to obtain a unit for evalua-
tion under operating conditions.
IA. Since one of the most consistent complaints from the field has
been that of radio Interference caused by gneretor units, I wish to
empasise that I feel that hers at last is a possible solution to this
hindrance.

11. I roommend theta generator set with this new brushless type
of a2.teraator be procured and a thorough evaluation be conducted.
12. I returned to Washington, D. C. on 18 November 1958.
