Title: Determination of gas consumption in catalytic reactions - for assessment of catalyst contact activity and selectivity involves production of hydrogen by electrolysis
Inventor: GUESSOW KLAUS DR
IPC: B01J19/00
Filed: 1975-01-04
Abstract: A catalyst reaction occurs is a suitable chamber to which hydrogen is supplied from an electrolysis process in a U tube, the oxygen produced being released. The electrodes are supplied from a constant current source which is switched on and off according to the pressure of the hydrogen gas in the reaction chamber. This is achieved by means of a manometer monitored by a light beam and receiver. The result of this is that the pulse shaped current waveform represents the gas usage, and this is integrated and displayed as a staircase type waveform on a graphical display unit. If too little hydrogen is produced, another circuit comes into operation to offset the reaction with a suitable material supply.

Title: Control circuit for domestic refuse compactor motor - adjusts motor current for returning ram at given maximum loading
Inventor: BOHNACKER GERHARD
IPC: B30B9/30
Filed: 1975-01-18
Abstract: The control circuit for electric motor driven ram of a domestic refuse compactor monitors the current of the motor. When a specified current value has been reached which corresponds to the final compacting pressure then the ram is returned to the starting position. This final maximum loading occurs only for genuine compacting requirements and in other cases much lighter loads are used. The current control relay B has a manually changed parallel current circuit R for adjusting the switching off current and hence the compacting pressure. The parallel circuit has a continuous or step by step adjustable regulating resistor R. The parallel current circuit is interrupted and the compacting pressure is determined only by the response current of the current control relay B.

Title: Thermostatic bath with oil recycle - using non-insulated resistance wire with resistance element thermometer and controller
Inventor: MAHLEN JUERGEN
IPC: B01L7/02
Filed: 1975-01-27
Abstract: Thermostatic bath has a metal heating tube containing a bare resistance heating coil of large surface area, low thermal inertia and low surface heat flux. The bath contains a non-conducting medium, e.g. oil and a circulation of this through the tube is obtained by an impeller located below it. In the lower part of the tube is mounted a temp. probe which is thermally contacted to both the heating tube and the element. The arrangement of heater, sensor and impeller are connected via a transfer channel to the inlet part of the measurement cells which allows the medium to flow upwards through the cell. The cells are separated by insulating walls with openings at the base so that the oil has to flow down the outside of the cell, up past the heating tube and back past the heating element. The bath is esp. for use with Ubbelodde viscometers. Commonly used baths have the disadvantage of poor homogeneity in the bath so that it is difficult to carry out simultaneous checks on several cells in the same bath. The system claimed uses commonly available components to give the accuracy of plus-or-minus 005 degrees C. required.
