Title: Magnetic non-return valve - adjustable position magnet controls magnetisable valve disc
IPC: F16K31/08
Filed: 1974-11-28
Abstract: The cylindrical plastic body (1) supports a cruciform structure (7) which coaxially locates the mobile steel valve plate (5). A plastic insert (2) forms a seal (4) for th evalve and provides support arms (10, 11) for the adjustable, externally threaded, magnet carrier (12). The magnet (13) may be adjusted relative to the plate turning the carrier. When inlet pressure is less than or only slightly exceeds delivery (6) pressure, the valve remains closed. Higher inlet pressures overcome the magnetic attraction and open the valve, but because the attraction reduces as the gap between plate and magnet increases, the valve does not close again until inlet pressure falls below the value which causes the valve to open. Continual opening and closing for small pressure fluctuations is thereby avoided.

Title: Oven for filter tube mfr. by powder metallurgy - employs rotating forming sleeves with set of peripheral slots for ventilation
IPC: B22F5/10
Filed: 1975-09-29
Abstract: An oven for making filter tubes by powder metallurgy, uses rotating sleeves inside which the tubes are inserted so that they retain their circular cross-section as they are heated. The tubes are made from metal powder, an organic binder and a solvent and in order to ensure an efficient removal of the binder, the sleeves carry ventilation holes. At the same time, this avoids a deposit of carbon inside the sleeves. The holes are formed as e.g. a set of rectangular slots staggered along and round each sleeve so that there is always an opening at any point along the tube wall. These slots have sides which slope outwards towards the outside, thus ensuring a Venturi effect for the flow of the controlled atmosphere maintained inside the oven, around the tube inside.

Title: Pressure relief valve for hydraulic pit props - has cylindrical body with flexible piston seal and ball located in fixed conical cup
Inventor: CHANAL ROGER
IPC: F16K17/04
Filed: 1975-11-03
Abstract: A cylindrical body (1) with a closed end contains a sliding valve composed of a flexible piston seal (11) surrounding a mainly conical metal cup core (10). On the other side of the core is another layer of flexible material (9) which forms a seal for a fixed conical plug (4) in the open end of the body. A ball (13) is held in the bottom of the conical cup and seals the inlet orifice (6) bored in the centre of the plug. Pressure at the inlet forces the valve away from the plug, thus allowing the fluid to flow down the conical face to the discharge ports (14). Since the conical surface causes the fluid cross section to increase as it flows out, the pressure is maintained almost constant above a certain level.
