  • Patent number: 6135414
    Abstract: Apparatus for coordinating the positions of valves in a pair of air flow passages along a jet engine nacelle to control two rotary valves from a single linear actuator. Each of the valves is of a ball type which is rotatable within a housing to achieve variable flow control in accordance with the particular shape of the opening through the rotatable valve member which varies with valve member rotation. The valve member bore shape may differ for the two valves, as well as the angle of the linkage between the linear actuator and each valve, to achieve different flow control relationships for the two valves from the single actuator armature. Each valve incorporates a pressure balancing member at the inlet seal of the valve which results in a reduction of the force of the seal element against the rotatable valve member when the valve is in the closed position, thereby reducing the torque required to rotate the valve out of the closed position.

  • Patent number: 6073880
    Abstract: Pairs of aerofins used for stabilization and control of missile flight are deployed through shared longitudinal slots provided in the missile body. Before launch, the pairs of aerofins, each pair comprised of a canard and a deflector, are retained in a folded position by a releasable latch mechanism within the missile body. The deflectors are mounted in a laterally displaced position from the longitudinal slots and are constrained from sliding into alignment with the slots by the presence of the folded canards. When the canards are released by the latch mechanism and permitted to extend outward to their deployed positions, the deflectors are able to laterally shift, effectively displacing the canards in the alignment position and subsequently deploying. The latch mechanism is designed to simultaneously release all the canards following missile launch, with biasing torsional springs operating to urge the canards outward through the associated slots to the extended position upon release.

  • Patent number: 5927716
    Abstract: In order to prevent stockpiling of tickets and to encourage the purchase of more tickets, a system is provided whereby game instructions are announced subsequent to distribution of the tickets. The game instructions notify the players as to which game areas in a ticket playing field they must unmask in order to win the interactive game of chance. The game instructions may be announced during a television program or radio broadcast or any other similar promotional activity and provide the players with the incentive to purchase tickets and to participate in the viewing or listening of the program or other promotion. To safeguard against stockpiling of old tickets, play areas that are not unmasked in accordance with the play instructions automatically invalidate the tickets. Unmasking of the play areas is undisguisable, allowing the game sponsor to readily determine which play areas have been revealed in accordance with the play instructions and which are in violation therewith and are, accordingly, invalid.

  • Patent number: 5887765
    Abstract: A caulk gun is provided with a forward-biasing mechanism to maintain contact between the caulk tube and the piston rod. The forward biasing mechanism is of simple construction and is piggy-backed to the trigger housing of the caulk gun. The operation of the forward-biasing mechanism relies on a friction grip which surrounds the piston rod. This friction grip is urged in the forward direction by a spring contained within the housing of the forward-biasing mechanism, and thereby biases the piston rod in the forward direction, while relieving the back pressure inside the caulk tube.

  • Patent number: 5887821
    Abstract: In a missile thrust vector control (TVC) system, two yoke plates are used which surround a pair of pivotably-mounted rocket nozzles. The rocket nozzles pass through corresponding elongated slots disposed on each yoke plate, the elongate slots engaging said rocket nozzles and operating to actuate the movement of the rocket nozzles in accordance with command signals issued by the missile autopilot. The actuator yoke plates are mounted for movement in orthogonal directions, and for rotation in unison. The orthogonal movement of the yoke plates effects corresponding movement of the rocket nozzles in the yaw and pitch directions. Simultaneous rotation of the yoke plates produces a relative twisting of the pivotably-mounted rocket nozzles causing thrust angles to deviate from the missile central axis in opposite directions but equal degree, thereby imparting a roll moment to the missile. In this fashion, any combination of movements of the missile during flight is made possible.

  • Patent number: 5846594
    Abstract: Fish of the Salmonoid family (salmon, trout and their relatives) is preferably first trimmed to remove heads, tails, fins, entrails, skin and bones and cut into fillets or loins to facilitate further removal of dark meat, bone, bruised meat, blood and viscera. The remaining light meat is then vacuum tumbled with a marinade solution under reduced ambient pressures at rotational speeds and for times dependent upon the thickness of the fish fillets or loins. During the vacuum tumbling step, penetration of the marinade solution into the light meat is facilitated and thereby the mobility and accumulation of curd-forming, soluble fish proteins are greatly diminished, serving to fix such protein in place, to ultimately provide a greatly visually-reduced curd product. Additionally, this vacuum tumbling step softens any pin bones which may remain to ultimately provide a virtually boneless product.
