Title: Vane pump with equalised viscous drag - has rotating vanes and rotor disc with hub mounted ring integral with pump cover
Inventor: PESCHKE RUDOLF
IPC: F01C1/36
Filed: 1976-01-24
Abstract: The pump or motor consists of a housing (6) with cover (2). A rotor is mounted with ball bearings (10) in housing and cover. Rotary vanes (4) are mounted between a rotor disc (1') and a ring (5). The ring is mounted over a hub (2') which is integral with the cover. The rotary vanes are pivoted by a lever (7) and a roller which runs over a cam surface. They are pivoted during rotation of the rotor, so that the vanes can pass through a narrow gap in the wall between pump inlet and outlet. As the hub over which the rotor moves is stationary, viscous drag acting on each end of the vanes is equal so that there is no torque load to be overcome.

Title: Monitoring circuit for emergency power supply - compares battery and charger voltage in differential amplifier whose output signal feeds indicator
Inventor: BECHTOLD LEANDER ING GRAD
IPC: G01R31/58
Filed: 1976-06-30
Abstract: The charger (1) output, or a part thereof as determined by a voltage divider (R1, R2, R3), is fed to one input of a differential amplifier (7). The other input is from a corresponding fraction of the battery (2) voltage. The amplifier drives a level detector and alarm relay circuit (12, 13). In normal operation the input voltages are balanced and there is no output from the amplifier (7). If there is a circuit break or a battery defect, the voltage imbalance is amplified and the relay trips. By incorporating a diode (9) in the amplifier output the circuit becomes responsive to ripple voltage as well as smooth DC. A small ripple bias (14) may be applied to the amplifier to improve the response of the system.

Title: Regulator for phase control of thyristor converter - has variable slope and amplitude sawtooth waveform generator
Inventor: JERMOLOVITSCH EDUARD STANISLAV
IPC: H02M7/162
Filed: 1977-01-11
Abstract: In a closed loop control system for phase control of a converter it is normal to work at a gain setting which is a max. for the worst possible conditions in order to avoid instability. This means that for a large part of the operating range the equipment is not working in the best possible state leading to low response and poor utilisation of circuits. The condition is overcome by introducing automatically variable gain into the circuit. It is achieved by connecting a second input (10) to the saw-tooth waveform generator (9) which is taken from a function converter (11) connected in parallel with the output of the error amplifier (2). The function generator adjusts the amplitude and steepness of the sawtooth wave thus changing the ratio between error and firing angle, and hence the gain of that part of the circuit, as a function of amplifier output.

Title: Wagon for nuclear fuel element transport containers - has space in chassis to receive container thus reducing overall height
Inventor: FEIND HANS
IPC: G21F5/14
Filed: 1977-07-07
Abstract: Wagon has a central hole in it chassis of sufficient size to receive the container, so that the container can travel with its bottom just above the level of the track. Adjacent to this hole are >=2 columns from which the container is suspended in position with its bottom end located in the hole. The overall clearance height required for a wagon complete with container is only very slightly greater than the height of the container itself. If the chassis is composed of two halves, these can be brought up to either side of the container without the need to raise the container and lower it into the chassis, in this way the height is also kept low in the container handling regions.

Title: Small fermenter for intensive and rapid cell cultures - has extended baffle plates in outer ring chamber
Inventor: VOLLBRECHT DIETMAR DR
IPC: C12M1/04
Filed: 1978-02-22
Abstract: Microorganisms or cell cultures are propagated continuously or discontinuously, under sterile conditions, in fluid nutrient solns., by means of a small fermenter. This consists of a vertical cylindrical container with an inner working chamber in which a rotary agitator is fitted on a shaft extending over the whole length of the container. Between the inner chamber and the outer container there is an annular chamber at the bottom of which there is a gas feed inlet. Projecting radially inwards across the outer chamber, baffle plates are fitted. These extend above and below the edges of the inner chamber over the length of the container and reach from the inner wall of the container to the outer wall of the working chamber. The fermenter is designed partic. to ensure a much better degree of transfer of the gases in the nutrient soln., in the outer annular chamber, and at the same time to reduce the length of time required for fermentation. The extension of the baffles above and below the working chamber intensifies the agitation of the fluid and the gases, whilst in the outer chamber a rapid, rising, laminar flow is set up. Cell densities of 2-20g. dry wt. per litre of nutrient or culture fluid can be achieved.
