Abstract: A therapeutic device is provided for where the therapeutic device made up of a unitary elongated piece having a distal end and a proximate end, where the distal end is the unitary elongated piece that is in a configuration to provide an elevated landing for lower or upper extremities, and is equipped with a material connected to the elongated piece and extending to a desired length and culminating at the proximate end, where this material implements a supporting means for the upper or lower extremities of a user, provided that these extremities are not resting on the elongated piece.

Abstract: The invention concerns a method of fabricating ceramic/metal or ceramic/ceramic composites. A porous surface region is produced on a ceramic material by sintering a granular substance onto the latter. Metal infiltrated into the porous region is then firmly mechanically bonded to the ceramic. Alternatively, the porous region provides a surface of large effective area to which another ceramic may be bonded chemically and mechanically.

Abstract: The invention concerns a temperature compensating bearing for a shaft in which an expandable helical ceramic member is provided between the shaft and the bearing housing. The expandable helical ceramic member functions by expanding and contracting sympathetically with any changes in shaft diameter due to change of temperature of the bearing.
