  • Publication number: 20130029960
    Abstract: The combined use—whether by adsorption or covalent linkage—of Melatonin adjacent any bone implant or graft, preferably any calcium- and oxide-containing artificial bone graft material, and more preferably a calcium aluminate composition. Alternatively, the bone graft or implant material may be used as a scaffold for tissue engineering.

  • Patent number: 6538422
    Abstract: A voltage sensing apparatus includes an output for a voltage tap point that is useful in representing the voltage on a conductor that passes through the voltage sensing apparatus. The voltage sensing apparatus also performs the function of a separable insulated conductor, e.g. a conventional bushing or bushing insert as utilized in the electrical power distribution field. The voltage sensing apparatus includes a molded body having an embedded capacitance screen that provides the output. The body is molded about the capacitance screen. An arrangement is provided for locating the capacitance screen within the molded body. In a preferred embodiment, the capacitance screen is molded from a conductive plastic preferably formed with an open mesh or screen structure that permits the free flow of molding material.

  • Patent number: 5747723
    Abstract: A modular artillery charge system consists of two distinct solid propellant harge modules. Each module consists of a three-piece combustible cartridge case design and bi-directional center core core ignition system. The three-piece combustible cartridge case consists of a combustible case body, having an open end and a end; a cap, having a closed end and an open end; and a center tube. The closed ends of the body and the cap have a hole in the center. The center core tube is positioned longitudinally through the combustible case body, and contacts the closed ends of both the cap and the body. The bi-directional center core ignition system comprises a core igniter bag and two end igniter bags. The core igniter bag occupies the center core tube, and the end igniter bags contact the core igniter bag. The bi-directional center core ignition system may be ignited by percussion primers or a laser ignition system. The first module is used individually or in groups of two.
