An osteal prosthesis having an outer surface splined in a direction generally parallel to its mean axis is capable of being secured in the bone without cement, the bone tissue developing so as to at least partly occupy the interior or hollow between the splines. The cross-sectional profile of the splines is such that it imparts a bone tissue retaining capability, and the longitudinal interior surf...

A disposable food receptacle for use in microwave cooking includes a provision to brown the exterior of the food in the receptacle by use of a thin layer 16 of an electrically conductive material, such as an elemental metal incorporated into the receptacle, so that the conductive layer will become heated by the microwave radiation and will, in turn, brown the exterior of the food in the receptacle...

A furnace for manufacturing silicon carbide comprises a broken ring (8) of raw materials in which is embedded a graphite electrical heating element (12). The ring (8) is free-standing and defines a central working space (32) in which is located a support (36). The furnace is enclosed by an annular wall (44) spaced from the ring (8) to define an annular working space. A track (38) is mounted on top...

Blood collection and transfer apparatus is adapted for autotransfusion in preoperative, operative and postoperative procedures.
