Further development of an electrolytic ? apere hour meter for submarine storage
batteries:
a. This instrument, which was used by the German Navy but was unknown to
the Russians, is the subject of experimentation by Dr. Eckard. Eclratd
was employed by a Soviet AG, which was recently dissolved, and is scheduled
to join the Oberepreewerk's image tube department. He will take charge
of the iconoseope developmentcut-Lined in the plan for 1949 - 1950.
b, Development of the ineter had been stopped as of the beginning of July i9/. .
The principal problem involved was the-temperature factoryas it affected the
measuring system.
c. The principle behind the operation of the meter is the electrolysis of
phosphoric acid and the observation of the amount of gas released in the
process,
The electrodes co:isist of nets covered 4th platinum black, which shut
off the actual electrolytic bath. While these nets are umter-tight, the
gas which is given off frog the bath is able to seep through. Upon the
reversal of the ourrcnt (charging), the platinum on the electrodes effects
catalytically the folloiiing combustion: 2H2402 : 2H20
A constant temperature was attained
a. Through the measurement of gas expansion in a chamber ;
b. Through temperature compensation in the tension-dividing resistor.

The following items were discussed:
a, High-efficiency oscillograph tube; target date 1949; 100,000 km./sec.
recordinpr snead lformer limits 50,000 Ion./sec.);
b. GzUicht-Fi] abtsster (10-inch viewing tube);
c, Projector "tube; picture dimensions: 2.5~x 2.5m; a shortage of smelting
metal is holding up production. No decision was reached on the question
of developing a small 20 kv home projector, similar to the Arnstadt model.
3. Six thousand coven-inch image tubes are scheduled for production by the end
of 1948. Glass components are being manufactured at G1ashlhtte Weisswasser
(Osram), but that plant is being gravely overworked. Steinbach (Leuchstoff
AG) has been 'unable to supply the yellow components (N2 yellow/2) for
luminous agents. The new suj'splier, Auergesellechaft, Berlin N 65, is making
experiments in the production of yellow luminous substances, but thus far
the crystals have turned out to be too coarse. They cannot, furthermore, be
mixed with N I blue/]. because of its white light. The principal current
b3ttleneck is the rhortage of cadmium. Fifteen kg. are needed. and 50X1-HUM
Anergesellschaft is attempting to procure the metal
Discharge tube development is under the supervision of Dr. Thouret, previously
of Osran. iercu=y high-pressure tubes of the following types vre currently
being produced:
100W 30AtVt
200 W 70 ".
500 W 30 "
1 KW 30-40 AtIt
2 KW 30-40'Ath, quartz bulbs
5 KW in process of development
The productive capacity of the quartzproce?ssing plant is low. Ltso
in production are 40 W, to At6. spectral lamps, sodium vapor lamps, both of
the Edison type, and'low-pressuro mercury tubes,
5. Neon lights for airfield illumination are being produced by the Oberspreewerk
at the rate of 50 to 70 per month. Various components are being produced by
the Pintsch firm, Berlin. The lights, which consist of soft glass tubes, .9m;
long and 40 to 50 mm. in diameter, are housed in tubes of harder glass.
6. Light bulbs (Blitzlampen): T = 0.002-3 see; voltage = 4,000 volts; current
1,000 Amps. These will be used for anti-aircraft searchlights. Their light
intensity will be greater than that of the suun's. They will consist of quartz
tubes c. one meter in length, 20mm. in diameter, which will be filled with
krypton. Electrodes will be of pure tungsten.
