4-oast iron base about 60 by 20 centimeters. The Motor operated on

20,000 rpm. The armature was air cooled, 10 centimeters in diameter,
Ant had -16 slots. There were 48 segments on the collector. Gloat
oars was taken in balancing the moving parts as well as in lapping
the bearings. A coin could be balanced on its edge any place on
the machine while it was operating at 50,000 rpm. The generator
output was 220 volts, two, to three amperes, and 800 OYoles at 15,000
spa.. The generator output was fed into-ac?step-up .(50 kilovolt)

at 50 to 60 kilovolts. The tube was pear-shaped, about 30
centimeters long and immersed in an oil bath. Spherw,gaps wore
used to measure the high potential. The exciter for the fAelde
was a small four-volt maohine,
rebuilt motor to be used for driving a camera to take 10 to
40 pictures per second of processes in Jenaphatm. This motor
was provided with three sets of windings, and its speed was.
variable from about 1,000 to 5,000 rpm.
One of the problems at Zeiss was to construct high speed grinding
equipment.. Very high speed gkindin *ill eliminate much rough
polishing and is much faster. a motor which turned 30,000
rpm. It could be geared to dr VG II wheel or spindle at twice
this speed. Another motor, which could.run at 60,000 rpm., was
almost complete This was to be used to drive an 50X1-HUM
Ultracentrifuge. There were two sett of ball bearings at each
end of the shaft. No separate races were used, but grooves Were
out directly in the axle shaft to guide the balls. All parts were.

18. Theis wis a great deal of fxiotion between the foreman of the
'electrical power supply Shop and the leader of the electron
microscope design work. OUYENOT had charge of the latter, and
LOW, laboratory worked, on the pbwer pack. It was desired
,that the microscope be operated at 50,000 volts, but 'sparking
Always took place when the potential exceeded 20000. It was
hoped and claimed by some that the instrument gave a' magnification,
of 20,000 but in reality 4,000 was rarely exceeded. OCTENOT
' insisted that the accessories made by LOT'S were at fault, so
he had ADO, Devlin, and Zech and Sterrett Dresden, each build
a plower unit. These were about twice as large, heavy, and bulky
xi the LOH unit and gave no better results. The upshot. wap
that, Mania was appointed to find out 50X1-HUM
where the trouble was.. OUDOT formerly worked on the A-1
apparatus and really was poorly trained to take over the tient, r 50X1-HUM
