摘要： An apparatus comprising two rasping halves conforming generally to the shape of the bone cavity to be produced, and a drive mechanism for reciprocating both rasping halves counter to each other in an axial direction. A rotary cutting tool in front of the rasping halves prepares the bone cavity to receive the rasping halves. A flexible drive shaft for the cutting tool extends between the rasping halves and rotatably within a drive shaft for the rasping halves. The latter drive shaft has a slot oriented at an angle to the axis of rotation of the drive shaft, and a pin projects from each rasping half into the slot, the pins being located 180.degree. apart. A bushing guides the movement of the rasping halves, and the pin from each rasping half extending through a slot in a housing for their drive shaft prevents twisting of the rasping halves.

摘要： A connection comprising two electrical conductor ends and a connection member fastened between them. The connection member does not extend beyond the external cross-sectional contour of the conductor ends, and preferably is formed of a material, such as silver, having higher electrical conductivity than the material of the conductor ends. The contact surfaces may be coated with gold. Alternatively, the connector member may be formed of copper, and the contact surfaces coated with silver. The connector member may overlap the end portions of the conductor ends, and pins arranged in aligned holes in the connector member and end portions. The connector member may be stepped, with a pin at each step, and may be formed of one piece or a series of strips one upon another. The pins may be formed as one piece with the connector member. The spacing between the pins may be greater than the holes which accommodate them.
