Title: Electronic phase control system - is for respiratory appliances and output of sawtooth generator is compared with voltage taken from voltage divider
Inventor: CAVALLO ROGER PAUL CHARLES
IPC: A61M16/00
Filed: 1975-02-20
Abstract: The apparatus controls cyclic operations consisting of successive phases whose duration must be proportional to that of the cycle. The output of an adjustable frequency saw tooth generator is compared with a voltage taken from at least one voltage divider (41, 42, 43). The signal emenating from the comparator triggers the successive phase modes of operation. The maximum tension of the saw tooth voltage triggers the cycle change. The outputs of the comparator are followed by a monortable device which generates control pulses for the phase mode and cycle change. These signals are applied to a four phase artificial resperator. The first signal of each cycle triggers exhalation and pumping stop. The second signal triggers exhalation and therefore pump depression. The third signal triggers the part inhalation phase, and pumping is stopped. The fourth signal triggers the cycle change and inhalation and the pumping in compression.

Title: Reciprocating engine with automatic valve operation - has sliding valve actuated by movement of main piston for reversing movement
IPC: F01B11/00
Filed: 1976-07-16
Abstract: The reciprocating engine has an inner cylinder (2) and an outer cylinder (5) separated by an annular space (6) which forms a passage-way to the lower inlet valve (7). Fluid enters through the inlet (13) in the valve housing (11) and flows through the hole (19) to reach the annulus (6) and inlet (7) to force the piston (1) upwards. Fluids in the upper part of the cylinder (2) flows out through holes (13, 16, 15). as the piston (1) approaches the end of its stroke the rod (30) is pushed upwards and pushes the slide valve (20) upwards. This movement of the slide valve (20) shuts off the hole (19) from the incoming fluid and connects to the exhaust port (15). The incoming fluid flows through the holes (16, 18) and reverses the piston movement.
