Title: Compressed air transmission for car - with regenerative braking using compressor and with auxiliary drive for compressor
Inventor: KOPPER WILLIBALD
IPC: B60K6/12
Filed: 1973-11-30
Abstract: The vehicle is fitted with several compressed air reservoirs with all or some of the reservoirs formed by the hollow chassis members for weight saving. The vehicle is driven by a compressed air motor. The brake pedal operates the brakes as well as a clutch to connect the compressor to the transmission so that the reservoirs are recharged via non return valves as a form of regenerative braking. The pneumatic dampers are likewise used to recharge the reservoirs. An auxiliary drive is provided by an electric motor driven by a battery to recharge the reservoirs by driving the compressor when the vehicle is stationary. A small internal combustion engine can also be used for this. The system enables a relative small power unit to drive a city vehicle, with large torque demands supplied from the reservoirs.

Title: Thermographic picture formation and reproduction - is by screen containing coarse and fine array of luminescent diodes responsive to different wave lengths
Inventor: MENKE JOSEF F DIPL ING
IPC: G01J5/00
Filed: 1975-07-19
Abstract: The procedure for producing and reproducing thermographic pictures uses a double screen with a coarse and a fine grid, the ratio of areas of square grid components being 16/1. The coarse and fine members are distributed over the screen in groups (1, 2, 3, 4) ... (11, 21, 31, 41) and comprise luminescent diodes with different colour responses. These respond to small temperature difference arising from a scene image on the screen, typically a landscape. The electronic circuit is formed by connecting groups of luminescent diodes in pairs to a series of operational amplifiers (5, 51, 6, 61, 7, 71), and series delay timing elements (8, 81, 9, 91). The equivalent temperature rise for a typical picture reception is calculated from an equation involving the geometry of the system, the intensity of light received per wave-length interval and the electrical and optical sensitivities.

Title: Small brushless DC motor - with additional reluctance effect to compensate for electromagnetic torque fluctuations
Inventor: MUELLER ROLF DR ING
IPC: H02K29/08
Filed: 1975-07-21
Abstract: The motor has a permanent magnet rotor and flat stator. It is of a type normally used for driving turntables or tape recorders. The flat stator (36) has several discrete disc coils energised sequentially by an external control circuit. Due to the sequential switching and the stator winding construction the driving torque fluctuates. Therefore, and iron ring (55), situated in the rotor leakage field, is added to the stator. The iron ring (55), which may also be used as a location for the stator winding disc (36), has notches on its outer perimeter. In conjunction with the turning rotor a reluctance motro action takes place which provides the torque compensation necessary for a more even drive.
