Abstract: Disclosed is a marine propeller for inboard, outboard, or inboard/outboard motors. The propeller is made from a non-metallic composite material that will not deform or deflect even at very high horsepower or RPMs. At the same time, the propeller is substantially less expensive than traditional metallic propellers. An especially unique feature of the propeller is that, unlike metallic propellers, it will shatter when it strikes a solid object in the water, thereby avoiding the engine and drive line damage that occurs when rigid metallic propellers strike a solid object. Also disclosed is a coupling member that permits the propeller to be adapted for use with most inboard/outboard motor configurations.

Abstract: In a bicycle frame including a plurality of tubes, at least one sleeve coupling connecting two of these tubes together, a separate pipe socket fastened within the sleeve coupling so as to project therefrom, with one of the two tubes being fitted around the pipe socket to contact the exterior surface of the pipe socket, and a layer of a metal adhesive or the like disposed between, and connecting together, the interior surface of the one tube and the exterior surface of the pipe socket, the exterior surface of the pipe socket is mechanically roughened.

Abstract: Claimed is an illuminated globe which is fully rotational about its axis. A translucent globe is slidably and rotatably mounted on an axial support pin and rests on a bearing surface. The axial support pin and the globe base are a unitary assembly. A lamp socket is affixed to the top of the support pin and the wiring is passed through the center of the support pin and exits through the side of the base.

Abstract: Device for use with a typewriter having manual half back space lever to permit making bold face characters. When bold face typing is desired, the device is removably secured to the typewriter, adjacent to the half-space lever, to permit incremental adjustment of the lever and typewriter carriage. By proper adjustment of the lever with the device, restruck characters can be made to have the appearance of bold face.
