Title: Chain driven vertical conveyor system - has curved paths to give momentary halts at loading or unloading levels
IPC: B65G47/57
Filed: 1974-03-04
Abstract: The system comprises a closed loop of driving chain driven via gears by a motor. The load carrying platforms are attached t the drive chain by two arms. At each level where loading or unloading is required, the chain drive is curved, forming a concavity facing towards the load supports. As the triangular framework moves through the curved section, the load attachment point is halted opposite the centre of the curve. The load remains stationary while the other ends of the bars move through the curve. This momentarily halt is used to transfer the loads from the platforms. The system can work in either direction.

Title: Controllable period sprinkler valve - has differential piston with regulator passage controlling time delay before closure
Inventor: HOBLIK RENE
IPC: F16K21/16
Filed: 1975-05-06
Abstract: A valve for a sprinkler system has a differential piston with a main bore (11) and an auxiliary adjustable (22) passage (21). The small side (10) of the piston is connected to the supply end (2) whilst the large side (12) operates in a chamber (18) connected via controllable passages (24, 25) to a similar chamber (19) into which the main bore (11) discharges. The second large chamber (19) is plugged by an adjustable (29) piston (27) with a conical outlet. When the passages (24, 25) are closed, pressure in the first chamber (18) rises to the supply valve at a rate regulated by the regulator passage (21). This forces the piston to the left, closed position in a set time, sealing the transfer port (11) on the seat (8). When the passages (24, 25) are opened, pressure in chamber (18) falls and the piston moves to the right until venturi action in the cone (27a) balances it and prevents further movement, the valve remaining open.
