Abstract: A rack for holding specimen slides. The rack has a frame with opposed support bars having opposed openings for supporting opposite ends of the specimen slides. The support bars have edges connected to sides of the frame, so that the support bars are resiliently deflectable with respect to the frame. The rack of specimen slides is containable in a slide case for purposes of transportation. The slide case has a base with a first latch portion, and the rack has a second latch portion. As the rack is positioned adjacent the base, the first and second latch portions are placed in juxtaposition to releasably secure the rack in the base. A cover is positionable over the base such that the base and cover fully enclose the rack of specimen slides. As the cover is closed over the base, the cover pushes the specimen slides against the opposed support bars, thereby deflecting the support bars and securing the specimen slides in the slide case.

Abstract: A container for coverslips is disclosed wherein the length and/or width of the internal receptacle area is adjustable by repositioning one or more partitions.

Abstract: An apparatus for testing shoe durability by simulating the leg movements of a runner using a flexible artificial foot to repetitively drive the sole of a test shoe against an abrasive wear surface. The artificial foot is controlled by cam-operated plungers which reciprocate in synchronization causing the artificial foot to repetitively move through a leg cycle in which the heel is first driven against the wear surface followed by the ball and then the toe with empirically predetermined forces such that a normal wear pattern is produced. The wear surface is supported on a carriage which is longitudinally movable relative to the artificial foot in response to the forces of contact of the test shoe against the wear surface, the carriage including an adjustable spring for selecting a desired resistance to carriage movement. A mechanism is provided for tilting the wear surface to simulate running on an uneven surface.
