Abstract: Facilitation of the trimming of edges by apparatus formed by a multi-sided member having a surface with a reservoir thereon that forms an opened pocket affixed to the surface, with the pocket having a base to which a handle is connected, and the surface having openings beyond the pocket to reduce the weight of the apparatus, with the open end of the pocket opposite the base and having a V-shaped edge, extending towards the handle, along which the surface is corrugated.

Abstract: Method and apparatus for electrical storage and pressure charging, by compressed fluid through a venturi, the electrical storage, where the electrical storage can take the form of a battery for operating a motor vehicle and electrical charges are produced by a generator operated by a turbine connected to a pressure storage tank operated when the storage charge falls below a prescribed level; in the method, stored compressed fluid operates a generator for charging the electrical storage.

Abstract: Apparatus and method for the fabrication of semi-flexible artificial rock sheathing; a one-coat silicone elastomer is brushed or sprayed upon the surface of a substantially flat natural rock formation to form a mold that is adhered to a wood-framed fiberglass cradle that hold the shape of the mold; when removed from the rock formation, the mold is sprayed with a thermoplastic elastomer to form a semi-flexible rock sheathing having the same characteristics as the natural rock surface from which the mold was formed; after the materials are fully cured, the sheathing sheet may be separated from the mold and used for the fabrication of rock, rock structures, by attaching sheathing sheets to the exterior of a framework, followed by cutting and forming different shapes.
