Abstract: A method and apparatus for making a cushion constructed of a gel-like substance and having a flexible mesh-like sheet embedded therein. The mesh is placed within a tray so that the edges of the mesh drape over the upper edges of the side-walls of the tray where they are held by elongated channel-shaped clamping members. Each clamping member has an inner leg which projects downwardly into the tray to position the mesh at a desired level within the tray. Corner clips overlap adjacent ends of the channel members to hold same tightly in position. A liquid substance is poured into the tray and it passes through the mesh to fill the tray to the desired depth. The tray is placed in an oven and heated at a predetermined temperature for a predetermined time whereby the liquid substance becomes a gel-like cushion with the mesh embedded therein. After the cushion has cooled, it is removed from the tray and the edges of the mesh are trimmed. The gel-like cushion can then be covered by a suitable casing.

Abstract: A pneumatically powered device for rotating, at a relatively high speed, a tool of the type used by a surgeon for performing an operation. A self-contained air motor is removably disposed within an elongated tubular housing easily held and manipulated by the hand of the surgeon and connected by swivel means to conduits through which a gas under pressure is delivered to and carried away from one end of the air motor. Coupling means extend from the other end of the air motor for connection to a tool, such as a drill bit.
