Patent DE-19708943-A1 (DE)
Title: Coathanger of two-armed bow and fitted hook
IPC: A47G25/40
Filed: 1997-03-05
Abstract: One of the arms (1) is hinged to the second arm (2) which carries the hook (4) over a swivel angle of around 180 deg and the swivelling arm (1) has an extension (9) angled upwards at the hinged arm end. The extension has a groove (5) forming part of a notch system completed by a strip (6) on the second arm and fitting into the groove (5). An endstop (8) at the end of one or other arm is used to arrest the other arm when the coathanger is folded. The swivel arm is joined to the non-swivel arm by a return spring which in turn holds the swivel arm in its splayed condition. Additional components include the swivel joint (3) between the two arms. The hook (4) should be gripped by the hand, using the thumb of this hand to depress the extension (9) so as to splay out the arm (1) to a point where it is arrested by the strip (6) engaging in the groove (5). When the arms are converged, the endstop (8) halts arm (1) so the two arms can be gripped and closed up by hand simply, thus disengaging strip and groove to initiate sprung re-set.

Patent DE-19717210-A1 (DE)
Title: Hydraulically damped elastomer mounting
Inventor: VERMAERKE FREDDY
IPC: F16F13/14
Filed: 1997-04-24
Abstract: The elastomer mounting has the elastomer between inner and outer concentric cylinders and with two hydraulic spaces (4,5) linked by flow restrictions. Rigid stops (6a,6b) limit the displacement in either direction. The hard stops are mounted in shaped recesses in the inner support and have small hydraulic spaces between the support and the stops. This provides a hydraulic cushion for each stop and prevents the stops from damaging the outer cylinder. Each stop has an equatorial groove gripped by elastic flanges to hold it in position. The mounting site can be clad with an elastic layer to complement the hydraulic cushion.

Patent DE-19725465-A1 (DE)
Title: Heat-recycling power engine for energy generation using cooling gases
Inventor: LAUBKEMEIER FRIEDHELM DIPL ING
IPC: F02G1/044
Filed: 1997-06-17
Abstract: The engine uses a thermodynamic circulation process with gradual contraction, where high pressure/high temperature of compressed air is reduced, and the recovered energy is recycled. Gradual contraction is carried out using a working cylinder (AZ-2) with working piston (2). The stroke frequency of this is a multiple of the piston frequency of another working cylinder (AZ-1), from where the compressed air flows to the first cylinder via heat exchangers (WT+NK). During this process, the pressure energy of one stage is used for recompression of the gas volume from a previous stage to the higher pressure level.
