  • Publication number: 20090139205
    Abstract: A pourable opaque centerport for solid propellant rocket motors and method for applying the same are disclosed. The pourable centerport inhibitor for solid propellant rocket motors has a curing system that includes a prepolymer and a curing agent. The prepolymer and the curing agent are combined to form a pourable polymeric binder that cures into an amorphous solid. The pourable centerport inhibitor also includes an opaque agent. The pourable centerport inhibitor may also include a plasticizer. The plasticizer, the prepolymer, and the curing agent are preferably the same type that is in the solid propellant with which it will be used in conjunction.

  • Publication number: 20070269528
    Abstract: The present invention is direct to a method of producing analgesia in a mammalian subject. The method includes administering to the subject an omega conopeptide, preferably ziconotide, in combination with an analgesic selected from the group consisting of morphine, bupivicaine, clonidine, hydromorphone, baclofen, fentanyil, buprenorphine, and sufentanil, or its pharmaceutically acceptable salts thereof, wherein the ?-conopeptide retains its potency and is physically and chemically compatible with the analgesic compound. A preferred route of administration is intrathecal administration, particularly continuous intrathecal infusion. The present invention is also directed to a pharmaceutical formulation comprising an omega conopeptide, preferably ziconotide, an antioxidant, in combination with an analgesic selected from the group consisting of morphine, bupivicaine, clonidine, hydromorphone, baclofen, fentanyl, buprenorphine, and sufentanil.

  • Publication number: 20070066386
    Abstract: The gaming system with phone card payout is a system for playing a video game using a smart card. A dispensing station includes a smart card reader, a bill acceptor and a phone card dispenser. The bill acceptor reads the monetary value of currency inserted in the machine and stores the monetary value on a smart card. The stored monetary value can be used to either purchase prepaid phone cards at the dispensing station or to play video games at an establishment hosting the dispensing station. The video games at the establishment are equipped with smart card readers. Logic in the video games verifies that the smart card monetary value was purchased at the hosting establishment and accepts the monetary value from a verified smart card for playing the video game. Video game credits accumulated on the game may be transferred back to the smart card.

  • Publication number: 20050056000
    Abstract: A system for draining fuel from the combustion chamber of a gas turbine engine in the event of a false start includes associated passageways and a straight through flow pilot air actuated poppet valve. The valve is normally open and actuated by the pilot air to close off the combustion chamber from the drain. A return spring biases the valve to open upon release of pilot air pressure acting on the valve. The valve housing has a piston section with a pilot air chamber and a section defining the passageways for the drain. The drain passageway extends along a straight path at an oblique angle to a piston axis along which a piston actuator moves in response to the return spring and/or the pilot air pressure. The valve also includes a position feedback system for detecting the state of the valve.

  • Patent number: 6033627
    Abstract: A closure and a device for use with a closure are described. The closure includes a first member having an interrupted beveled edge, a second member having an undercut edge, and optionally a base member to which the second member is fixed. The first member is adapted to be received with the interrupted beveled edge retained by the undercut edge. A test device can include such a closure and can also include a hinge between the first and second members. Test elements, such as a chromatographic medium, an absorber, an applicator, or a sample application zone, can be disposed on the first member and/or the base member and can be brought into opposition by closing the first member with the closure. The beveled edge is interrupted by one or more uncut portions or bridges. A testing device according to the present invention can perform a number of types of immunoassays, including unidirectional assays, bidirectional assays, and assays employing a split flow path.
