  • Patent number: 6052921
    Abstract: This invention relates to a shoe having an ergometric shoe lace design. The laces pass through tubes on the tongue portion of the shoe and extend down to the sole of the shoe on either side of the shoe where they pass through tubes on or near the perimeter of the sole. The laces criss cross the foot in this manner to secure the foot from up and down motion in the shoe. Optionally the lace may continue to be wrapped around the heel of the foot through ankle tubes and heel tubes to secure the foot from toe to heel movement in the shoe. This is particularly of advantage for shoes used in sporting activities. In this manner the upper of the shoe is not pulled together on either side of the tongue as in conventional shoes, thus avoiding stresses in the upper that tend to put pressure on and rub against the user's foot. Thus the shoe is comfortably and securely held to the users foot.

  • Patent number: 5883713
    Abstract: A Fourier transform interferometer for rapid scanning of scenes such as explosions wherein an incoming beam of light to be analyzed is split by a beam splitter into a first portion and a second portion. The first portion of the incoming light is sent down one arm of the interferometer where it passes through a rotating scanning cube for changing the path length in that arm of the interferometer. The light is then reflected by a retro mirror and sent back through the scanning cube to the beam splitter for sending a portion of the returning beam to a detector. The second portion of the incoming light is sent down a second arm of the interferometer where it passes through a compensator. The light is then reflected by a retro mirror and sent back through the compensator to the beam splitter for sending a portion of the returning beam to a detector. The first and second portions of the incoming light having differing path lengths interfere and the detector measures the fringes created.

  • Patent number: 5862800
    Abstract: This invention provides a molten salt, solar central smooth tube receiver that is able to effectively absorb a peak solar flux of 1.42 MW/M.sup.2 by constructing the receiver from low cycle fatigue 625 alloy. Although higher flux levels are attainable for a smooth tube receiver by reducing the tube diameter to increase the salt's heat transfer coefficient, the receiver's size is optimized at this flux level to minimize capital and performance costs. Analogously, material provides substantial performance and capital cost improvements for receivers constructed with internally enhanced film coefficient tubes. The receiver's cost is minimized by utilizing autogenously welded and drawn tubing with the weld located at the tube's neutral axis to provide minimal strain at the weld.

  • Patent number: 5862670
    Abstract: Leakage of propellants such as oxygen and hydrogen in an enclosed environment in the atmosphere can lead to fires or explosions. For storage tanks on reusable launch vehicles such as the space shuttle where propellant is to be stored in the cargo bay of the vehicle, the storage tank should be filled while the vehicle is at a safe altitude to avoid the dangers associated with propellant leakage. The invention a process for filling propellant tanks at safe altitudes where if there is propellant leakage ignition will not occur. The process involves launching the vehicle with an inert gas in the storage tanks, dumping the inert gas and filling the tanks in the cargo bay from the main propellant tanks during the launch once the vehicle is at a safe altitude. The propellant can be dumped overboard and the storage tanks filled with an inert gas in case of a mission abort if the vehicle needs to make an emergency landing.

  • Patent number: 5850831
    Abstract: This invention reduces a molten salt, solar central receiver's size, pressure loss and cost by using a loose-tight-loose twist, twisted-tape insert inside the receiver's tubes to enhance the tube's heat transfer coefficient. This twist staging is designed to provide a higher heat transfer coefficient in the receiver's central region where the solar flux is high and a reduced pressure loss at the low solar flux entrance and exit end regions. Because the twisted-tape enhances the tube's heat transfer ability it can be made larger in diameter than a smooth bore tube at an equivalent pressure loss. This reduces the number of tubes which results in a substantial reduction in receiver cost.

  • Patent number: 5837206
    Abstract: A V-shaped singlet delta oxygen manifold for a chemical iodine oxygen laser wherein singlet delta oxygen is produced in one or more reaction zones and enters the interior of the V-shaped manifold. The V-shape of the integral manifold causes the singlet delta oxygen containing gas to undergo rapid change in flow area and a consequent rapid increase in velocity. The integral manifold also directs the singlet delta oxygen entering the V-shaped manifold to the open end of the V which is connected to a nozzle for injecting singlet delta oxygen into a laser cavity for providing energy to a laser beam. The V-shape enables a uniform pressure along its arms for introducing the singlet delta oxygen to the inside of the singlet delta oxygen manifold and directs the flow of the singlet delta oxygen to the nozzle.
