Title: Flat plate valve slider - has obtuse angled edge to match V-shaped sealing strip in valve body
Inventor: WEHR HUBERTUS
IPC: F16K3/02
Filed: 1973-06-27
Abstract: A VEE-shaped sealing strip located in a groove in the valve body, is compressed by the edge of the valve slider plate when it is in the closed position. The seal form utilises the fluid pressure to increase its sealing capacity. The two sealing strips which are placed across the valve body for sealing the two opposite faces of the slider plate, have knife edge sealing lips so that the pressure medium can assist its sealing function. The inner sealing surfaces of the round gasket join each other at a blunt, sharp or right-angled, angle, although the former has shown itself to be particularly advantageous since it requires less preparation of the outward gliding surfaces of the even driver and a cutting effect is achieved upon the closing of the driver. By this means a locking of driver is not possible.

Title: Boiler feed water automatic control - prevents corrosion, steam wastage and incorrect dosing during shutdown
Inventor: SCHULZE HANS
IPC: F01K9/02
Filed: 1973-08-28
Abstract: The Parent Patent describes a boiler feed water train with automatic control for preventing excessive steam blowdown loss, boiler corrosion and excess dosing or under-dosing of chemicals during short periods of shutdown. A water level sensor in the feed water tank switches on a first timing relay causing dosing of chemical from a first dosing unit for a predetermined period before the condensate pump is switched on to bring the water level back to the maximum; when the maximum is reached, a second timing relay is switched on causing a second metering unit to operate for a predetermined period; the blowdown valve is shut again when a thermostat indicates that the miminum temp. has been reached. In the Patent of Addition, a press-ostat (pressure regulating device) monitors the vapour pressure in the feed water tank and, when this pressure drops below a predetermined level, switches on the staring circuit for a heating pump, which then operates until the vapour pressure returns to the desired value; at the same time, a third timing relay switches on a third metering unit which injects into the lower end of the deaerator for a predetermined period.

Title: Shock absorber piston for high shock loads - spring loaded valve opens in response to inertia force to give low damping at high acceleration
Inventor: OVERKOTT FRANZ JOSEF
IPC: F16F9/348
Filed: 1973-12-22
Abstract: The piston of a shock absorber includes a facility to reduce the damping to a minimum when extremely high shock loads are applied. Normal damping is provided by flow through orifices passing directly through the piston. A sealing plate is spring loaded against the piston to seal off auxiliary orifices. A shock load of sufficiently high acceleration level induces a dynamic pressure on the underside of the sealing plate and this is displaced vertically to permit flow through the auxiliary orifices. In this condition the damping factor is substantially reduced.
