Abstract: The invention provides a faster, safer, more reliable and cost-effective method to permanently or temporarily repair leaking in-service pipes than welding and other devices and methods currently used to repair leaking pipes. The interlocking pipe clamp and internal circumferential self-pressurizing seal, installed in a recessed seal groove within the clamp housing, embodies a unidirectional fluid orifice leading to an internal pressure responsive chamber whereby trapped fluids inside the chamber expand outwardly under pressure to force the external sealing surface of several pliable, multi-combed and conjoined fingers to form a series of redundant seals against the leaking pipe with increasingly greater force to prevent the escape of fluids from the pipe and to prevent seal dislodgement from the pipe repair clamp. The seal material is composed of resilient synthetic and natural materials which are corrosion and fire resistant and color coded for specific fluid repair applications.

Abstract: This invention relates to pipe coupling with multi-combed, self-pressurizing internal seals and an integral pipe fastening system to join and seal pipes of all sizes, fluid contents and line pressures. The invention embodies a coupling body, two pressure responsive seals installed in recessed seal grooves located at opposite outside edges of the pipe coupling body, and seal body consisting of a unidirectional fluid inlet and internal pressure responsive chamber and an external sealing surface comprised of several resilient, multi-combed and conjoined lips and fluid pockets which form a series of redundant seals around the outside axial surface of pipes joined within the coupling. Fluid escaping from the pipe juncture enters the internal pressure responsive chamber through the unidirectional orifice wherein trapped fluids expand the pliable external multi-combed seal surface against the axial surface of each pipe with corresponding force to prevent the outward flow of fluid from the pipe coupling.

Abstract: A flashlight for dispensing a substance from an aerosol canister, the flashlight including an elongated housing having a front end, a rear end, and a central longitudinal axis, the aerosol canister being slidably received within the housing. At least one light emitting diode disposed approximate the front end of the housing and an elongated spray tube having a proximal end and a distal end, the proximal end being connected to the aerosol canister and the spray tube extending parallel to the central longitudinal axis such that the distal end extends beyond the front end of the housing.

Abstract: A projectile with a frangible shell having both an exterior surface and an inner cavity. The exterior surface is made up of a plurality of polygonal panels. The inner cavity contains a dispersible substance. The frangible shell may have a spherical configuration formed by fusing together two hemispherical shells. Also, a method of manufacturing projectiles. In the method, two hemispheres are formed. A dispersible substance in tablet form is inserted into one of the hemispheres. The second hemisphere is then brought into contact with the first hemisphere and the two are fused together to form a spherical shell. Finally, the tablet is disturbed so that the dispersible substance is freed within the inner cavity. Sonic energy may be provided in order to weld the two hemispheres together and also to disturb the tablet. The hemispheres may have an exterior surface made up of a plurality of polygonal panels.
