Abstract: An assembly includes a flange that can be fixed to an interior wall structure, such as an electrical box. A planar surface of the flange abuts the outer surface of the wall substrate thus providing tight contact between the wall substrate and the interior structure. Mating elements of the flange engage an electrical device to maintain the device in flush and parallel alignment with the substrate.

Abstract: A fastener device and assembly comprises segmented arms of rectangular cross section that extend inwardly from a central opening in a surface of the device body. A distal end portion of each segment arm comprises an internally threaded portion, to collectively form a single thread engageable with an externally threaded fastener. Centering portions enhance alignment of the device when applied to the externally threaded fastener.

Abstract: The present invention consists of improvements in silicone emulsion blends that provide a unique, useful and reliable composition and means for protecting and aesthetically enhancing the surface of rubber and other natural and synthetic polymers, leather, and wood. Specifically, the present invention consists of an emulsion blend comprising (1) an aqueous emulsion of polydimethylsiloxane and (2) an aqueous emulsion of organopolysiloxane which upon drying forms a solid elastomeric film of siloxane; and a polyol.

Abstract: A picture frame mat opening cutter is adapted for cutting both circles and ovals and depth of cut can be controlled by the amount of downward pressure applied during use. The cutter body mounts a retractable cable wound on a rotatable spool; a cutting blade mounted on a spring-loaded, slidable support bar; and a rotatable, vertically movable control knob which bears on the support bar and is manually grasped and manipulated for moving the cutter and controlling the depth of cut according to the amount of pressure applied to the knob. Beveled oval and circular picture frame mat openings are cut utilizing the retractable cable in conjunction with positioning pins on the surface of a mat to be cut. By modification, straight line cuts are also obtainable.

Abstract: A versatile mat opening cutter is adapted for cutting circular and oval openings, rectangular openings and, with the aid of a template, special shaped openings. The cutter body mounts a retractable cable wound on a spring-loaded, rotatable spool, an adjustable cutting blade, and a template follower. Circles and ovals are cut utilizing the retractable cable and positioning pins on a working surface. Special shaped openings are cut by using a template and the template follower.
