Abstract: Electrical wire connector for a twisted pair of electrical wire ends, wherein the electrical wire connector has a heat-shrinkable inner portion which will provide a water-tight, electrically-insulating covering of the electrically-conductive junction after the electrical wire connector is applied and heated. In preferred embodiments of the present invention, a heat-shrinkable inner portion is visually distinct from a non-heat-shrinkable outer portion, so that the action of the heat-shrinkable inner portion is visually observable.

Abstract: Improved engagement is achieved between a sprocket having a plurality of flat-topped teeth and an endless conveyor belt. The belt is formed from a plurality of generally flat load-bearing tabular rectangular modules disposed in transverse rows along the belt with the longer sides of each module positioned transverse to the direction of motion of the endless belt, the modules being hingedly connected to and extending between spaced rods, which pass through co-axial, equally-spaced eye portions projecting from the longer sides of the modules, the endless belt having a first load-bearing surface and an opposing sprocket-engaging surface.
