Abstract: A procedure for contouring the wall of a femoral cavity in a femur for the reception of a femoral stem to be seated within the femoral cavity employs a femoral broach which includes cutting teeth aligned along peripherally spaced apart longitudinal rows extending along a portion of the outer surface of the blade of the broach for forming a multiplicity of alternating longitudinally extending generally parallel grooves and ribs in the wall of the cavity, at least some of the grooves being contiguous with harder portions of the bone of the femur while the ribs are comprised of softer portions of the bone so that completion of the contouring will be signalled by bottoming of the blade of the broach upon the harder portions of the bone and upon implant, the femoral stem will be seated upon the harder portions of bone while the softer portions of bone will be compressed between the femoral stem and the harder portions of bone to accomplish fixation by an interference fit.

Abstract: A tractor ball assembly to be mounted on the tongue at the rear end of the tractor having a plurality of balls to match the variously-sized sockets commonly used. The ball is mounted on a base which rests on the tractor tongue. Frusto-conical sections of identifical size and shape diamatrically opposed are cut in each ball and the upper side of the base has a surface complementary to the surface of one of the frusto-conical sections. A bolt, the under side of the head of which is a surface complementary to the ball frusto-conical surfaces fits into aligned holes in the ball, base and tongue and upon being tightened keeps the ball from slipping with respect to the base and/or the bolt.

Abstract: A holder is selectively secured to the stage of a microscope for adapting the microscope to hold a test tube oriented horizontally between the microscope objective and a light source for microscopic examination of a biological specimen while retained in the test tube, thereby eliminating the necessity of preparing a microscope slide for the specimen. The holder includes a base assembled of slotted base plates selectively slidable relative to one another to be fitted to the microscope so as to establish a slot for retaining the test tube in registration with the microscope objective and the light source, and fasteners for fastening the base plates together in secure attachment to the stage of the microscope.

Abstract: An improvement in an internal combustion engine of type in which a piston reciprocates in a cylinder to compress a charge of fuel within a combustion chamber within which the charge of fuel is ignited to burn and drive the piston through a power stroke, the improvement providing the combustion chamber with a first stage chamber and a second stage chamber communicating with one another through a valve operated in synchronism with reciprocation of the piston to close communication between the first stage chamber and the second stage chamber as the piston approaches top dead center so as to enable ignition and burning of a first portion of the charge of fuel in the first stage chamber, isolated from a second portion of the charge of fuel in the second stage chamber, and then to open communication between the first stage chamber and the second stage chamber to effect ignition of the second portion of the charge of fuel in the second stage chamber by the combustion products of the first portion of the charge of fu
