Patent DE-2659137-A1 (DE)
Title: Double acting hydraulic shock absorber cylinder - has flow throttles to cushion end of piston stroke and prevent recoil
Inventor: FAEHRMANN KURT
IPC: F16F9/49
Filed: 1976-12-28
Abstract: A hydraulic shock absorber cylinder for vehicles has a double acting piston which is equipped with throttle discs on either side of the piston seal. Since the hydraulic fluid in the cylinder is able to flow from one side of the piston through an external connection to the other side, the flow velocity controls the piston movement. The throttle disc, attached to the piston by a coil spring, obstructs the outlet ports so that the final amount of hydraulic fluid is displaced at a reduced rate. This method produces a cushioning effect on the piston movement and therefore shock absorber recoil is prevented.

Inventor: IHLEFELD KARL-HELMUT
IPC: E04B1/94
Filed: 1977-06-29
Abstract: The statically loadable lightweight structural element for walls, floors or ceilings affords a high degree of fire resistance and heat and sound insulation. It comprises a load-bearing frame filled and sealed with a structure of composite mineral fibre panels. Only oen covering layer(3) of the composite panel is attached to the frame(5). The mineral-fibre-lamellae layer(1) is thicker(6) than the frame structure, so as to cover it completely.

Title: Switching contacts for electrical temperature control - consist of two blades moved in opposite directions by piston sliding inside housing
Inventor: WERNER GEB ROTH MICHAEL
IPC: H01H5/20
Filed: 1979-01-26
Abstract: The switching contact arrangement with a small length of travel is suitable as a two point controller for electrical temperature control. This has two identical resilient switching blades in a tandem arrangement. They are operated by the sliding action of a shallow piston inside a housing. By means of the piston movement, the two blades are moved together in opposite directions. This reduces sparking and corrosion at the contact region. They are held at a tension which overcomes a fixed supporting tension.
