Title: Fuel supply system for supercharged engine - has butterfly valve downstream of supercharger to prevent oil loss
IPC: F02D23/00
Filed: 1975-02-14
Abstract: The fuel supply system applied to engines fitted with exhaust driven turbo-superchargers has a compressor (1) which draws air through the piston type carburettor (2) and delivers it to the engine through the butterfly valve (3). The butterfly valve (3) is on the downstream side of the compressor (1) and has the result that when the valve (3) is closed to decelerate the engine, the depression induced in the impellor chamber (4) is insufficient to cause oil to flow out of the supercharger sump (5) as is the case when the valve (3) is fitted between carburettor and supercharger. Any surplus fuel remaining in the carburettor bowl (6) is returned to the fuel tank by the pump (8). The sponge material (9) prevents the fuel splashing about.

Title: Ante-natal foetus monitoring system - calculates parameter from area between curves representing heartbeat frequencies
IPC: A61B5/024
Filed: 1975-03-14
Abstract: The system automatically monitors the foetus before confinement. The normal or base level of foetal cardiac frequency is determined and compared with the values of this frequency when slowed down. A parameter is calculated instantly, proportional to the surface area, between the graph of the frequency curve on slowing down and the extension of this curve corresponding to the base level. A detector can be placed near the foetus for its heartbeats, the detector signals being electronically transformed into a voltage proportional to the heartbeat frequency.

Title: Pulse generator supplying capacitance load - has regenerative circuit for recharging generator output stage capacitor which is charged also from DC source
Inventor: MASUDA SENICHI
IPC: B03C3/68
Filed: 1977-07-13
Abstract: The generator can apply repetitive controlled pulse voltage waves to a highly capacitative load (21). The generator output capacitor (C1) is charged from a d.c. source and switched (So) to the load via a current limiting inductor (L). The effect of the inductor is also to give a controlled voltage rise time. The switch (So) is opened and, after a controlled interval, an antiparallel switch (S1) is closed. The charge on the load is then partially transferred back to the output capacitor (C1) with a controlled voltage decay time. The load is finally cleared of its residual charge by a dumping circuit and switch (S2) in parallel with the generator. The cycle can then be repeated. The switches are solid state devices under the control of a sequencing unit (9). The circuit has low losses.
