Abstract: A cable lock system having a length of cable, a female lock housing and a male lock housing. The cable has a lug attached to each of its ends and after the cable is wound through the various apertures of items to be secured, the lugs are inserted into lug apertures in the side wall of the tubular sleeve portion of the female lock housing. The male lock housing has a cylinder bore hole and a lock having a locking tang fixedly secured in the cylindrical bore hole. The male lock housing is telescopically received in the bore hole of the female lock housing with its front end pressed against the respective lugs on the end of the cable member. By turning a key in the lock, the locking tang is directed radially outward into an internal annular groove in the female lock housing thereby preventing removal of the male lock housing from the female lock housing. The structure of the assembled parts prevents access to a rounded head nut on a carriage bolt that secures the female lock housing to a support wall.
Abstract: The system eliminates the noise, rumble and hiss from any standard 35 mm analog optical sound track. By simply feeding the film through the projector sound head in a normal manner the system automatically converts the analog optical sound tracks to digital quality. No special storing of digital data on film is required and no special digital decoder equipment is needed. The system produces noise-free sound, increased frequency response, expanded dynamic range and clarity of the dialogue. Film studios will no longer need to carry a double inventory of films having digital and analog sound tracks or to process the sound tracks for noise reduction.
Abstract: A lighting system is designed to replace incandescent lighting by alternatively adapting existing recessed incandescent fixtures to accept more efficient lamps such as fluorescents, or using specially designed recessed lamp fixtures. In either case the invention addresses the problem of overheating of the on-board power stabilizing circuitry which almost universally occurs when an enclosed fixture designed for incandescent lamps is fitted with fluorescent replacements. Rather than installing the power stabilizer in the enclosure with the hot lamp, the power stabilizing circuitry is physically removed from the interior of the lamp housing and isolated at a remote position. The preferred embodiments house these electronics in a separate insulated ballast housing.
Abstract: A toilet seat and lid, each comprising a rigid insert injection molded of thermoplastic material. Each insert is then over-molded by injection molding with a thermoplastic elastomeric material which provides the outer surface of the seat and lid. The inserts are dimensioned with respect to their over-molded surfaces to be smaller than the finished seat and lid and are designed to give maximum strength to the seat and lid. Each insert is shaped to promote the flow of the over-mold material and to minimize shrinking, swelling or distortion of the insert. The elastomeric material is preferably chemically compatible with the inserts to allow a chemical as well as a mechanical bond to take place. The over-molded material provides the desired soft, non-slip, warm to the touch outer characteristics of the seat and lid.

The neck support assembly has a Y-shaped support member having foam cushion members mounted on its upwardly extending arms.
Abstract: A strong, durable, lightweight long gun stock comprising a rigid insert molded of reinforced thermoplastic material together with a foaming agent. The insert is over-molded with a thermoplastic material which provides the stock with the desired surface characteristics. The insert is dimensioned with respect to its over-molded surfaces to be smaller than the finished stock and is designed to give maximum strength to the stock. The insert is shaped to promote the flow of the over-mold material and to minimize shrinking, swelling or distortion of the insert. The over-mold material may be a hard, un-foamed material or a thermoplastic elastomer. The hard un-foamed over-mold material mechanically bonds with the insert and provides the stock with an extremely smooth, hard outer surface. The thermoplastic elastomer over-mold material is compatible with the material of the insert and bonds both mechanically and chemically with the insert, providing the stock with a soft, quiet, non-slip surface.
Abstract: A synthetic grip for a handgun (specifically a revolver) that does not require any separate attaching components. The grip is attached to the handle frame by engaging the existing frame stock pin with the grip's own spring tension resiliency. The grip has a U-shaped molded assembly having a front wall portion and two side wall portions extending rearwardly from the outer edges of the front wall portion for engaging the side walls of the handle frame. Each side wall portion has a groove in its inner surface extending substantially from its top end to its bottom end thereby forming a track for receiving the opposite ends of the stock pin extending outwardly from the side walls of the handle frame. Adjacent the bottom end of each of the grooves is a recess that captures the ends of the stock pin. The grip is preferably made from a hard plastic U-shaped core member that has been overmolded with a resilient layer of plastic material.
Abstract: A tubular tapered composite pole for supporting utility lines and a method for making the same. The pole is formed from a plurality of elongated panels made of pultruded composite material having a height H1 in the range of 30 feet-120 feet. An interlocking structural groove is formed on one of the side edges of the panel during the pultrusion process. The other side edge of the panel is formed by a biased angle cut from the bottom edge of the panel to its top edge to give it a generally trapezoidal shape. A tongue shaped interlocking structure is machined along the length of the angularly cut side edge. The panels have a length L1 along their bottom edge in the range of 6″-24″ and a length L2 along their top edges in the range of 3″-16″. The respective tongue and groove structure along the side edges of the panels is interlocked together to form a closed loop extending from their top edges to their bottom edges to form the tubular tapered pole.

Abstract: A skateboard deck and a method of making the same. The initial stage of making the skateboard deck comprises the step of stacking multiple veneer layers of wood upon each other and applying a coat of glue between each layer and then pressing the layers in a hydraulic press to form a first block of wood. Next the outline shape of the skateboard deck is formed on a CNC shaper machine. Following this two sets of four bore holes are machined in the first block of wood and they are counterbored on the initial top surface of the skateboard deck. Truck mounting inserts are then pressed into the bore holes in the initial top surface of the skateboard deck. One or more veneer layers of wood are then stacked onto the initial top surface of the skateboard deck and a coating of glue is applied between each layer and they are pressed together in a hydraulic press to form a second block of wood. The second block of wood is trimmed to the same shape programmed previously.
