Patent DE-4334551-A1 (DE)
Title: Hydraulic actuation device
Inventor: JAKOBI DIETER
IPC: F16D48/02
Filed: 1993-10-11
Abstract: An actuation device for a separable coupling in the driveline of a motor vehicle is disclosed. The said actuation device is intended largely to prevent load impacts in the driveline. This is achieved by a throttle valve in the hydraulic line between master cylinder and slave cylinder. The throttle valve provides a closing element, which is pressed by a compression spring against a sealing surface on the valve-housing side. When the coupling is opened the closing element is lifted off from the sealing surface and an unrestricted flow of hydraulic fluid is ensured. When the hydraulic fluid flows back from the slave cylinder to the master cylinder, the closing element admits the flow only through a small flow passage, resulting in a partially throttled return flow.

Patent DE-4412474-A1 (DE)
Inventor: ERNST VOLKER
IPC: B01D46/00
Filed: 1994-04-14
Abstract: An air filter, particularly for the intake air of an internal-combustion engine comprises a housing 13, an air filter insert 16 arranged in the housing, and a cover 10 closing off the housing 13. The air filter insert 16 consists essentially of a rectangular cartridge which has a surrounding seal 18. This seal 18 is clamped in between the housing 13 and the cover 10 in such a manner that it separates the unfiltered-air space from the filtered-air space. In addition, locking elements 19 are provided by means of which a fastening of the cover on the housing and therefore, at the same time, a fastening of the cartridge in the housing is permitted. The invention consists of the fact that the support of the cover on the housing takes place only in the area of the locking elements 19 and simultaneously the seal has a very low Shore hardness. As a result, the cover no longer rests as previously on the housing over the whole length of the seal but only in the area of the locking elements. <IMAGE>

Title: Heat accumulator for a system for accumulating thermal energy and cryogenic (refrigerating) energy
Inventor: IM JONG-SUNG
IPC: F25B13/00
Filed: 1994-06-07
Abstract: The system comprises a multiplicity of heat accumulator units which are coupled to one another serially or in parallel via a heat exchange tube (heat transfer tube). The thermal accumulator units can be charged with phase materials having different melting points. As an alternative, the thermal accumulator units can be charged with phase-change materials having the same melting point. If phase-change materials having the same melting point are loaded into the accumulator units, the accumulator units are equipped with appropriate pressure-control units. A prescribed temperature of an accumulator unit is chosen for use in the thermal accumulator of the present invention with the aim of increasing the thermal efficiency of the system. In addition, the thermal accumulator minimises the loss in the heat exchange between the heat exchange tube and the phase-change materials. The system alternatively carries out heating or cooling operations without an attendant need to exchange the phase-change material for a different phase-change material.
