Title: Hip joint prosthesis with shaft
Inventor: MOOS NORBERT DR
IPC: A61F2/36
Filed: 1994-08-09
Abstract: A shaft of constant thickness at the distal end runs straight in on the medial side. The prosthesis thickens out from medial to lateral sides to form steps (16) on the ventral and/or dorsal sides. The steps run straight in the distal part (2) of the prosthesis as against parallel to the medial side in the proximal part. The triangular surface formed by the medial-proximal shape is adjoined by a collar (11) forming the medial-proximal boundary of the prosthesis. An additional step (9) fitted proximal to the lateral side (5) starts from an extension (8) proximal on the lateral side only to extend in the proximal direction where it increases in thickness before arching round into the proximal boundary and collar (11). The ventral-dorsal thickness of the shaft increases in the proximal sense, and a neck (17) medial-proximal adjoining the collar seats a cone (18) to take ceramic or metal plugs. The prosthesis is cemented into place, or again has a roughened surface to fit home without cement.

IPC: F01K25/10
Filed: 1994-09-13
Abstract: The system utilises environmental heat energy and waste heat and consists of an evaporator (1), compressor (2), pressure converter (5), liquefier, and a throttle (4). The vapour from the evaporator is compressed in the compressor to maintain the circuit operation, but safeguards a highest possible performance. A part of the compressed vapour is liquefied in a condenser (3) and re-evaporated for obtaining an extra vol. expansion work. Another part of the vapour from the compressor is fed to the pressure converter to attain a different pressure level with air etc. inclusion for generating a mechanical work. Resetting in the pressure converter is enabled by vol. reduction in any circuit point. The liquefied vapour from the condenser can be expanded in the throttle for a new cycle.
