  • Patent number: 6371146
    Abstract: An improved fuel level responsive peelaway action valve for vehicle fuel tanks, in which a float moves a valve closure element into sealing contact with a vapor venting outlet, and then pulls or “peels” the valve element off the vapor venting outlet when fuel level drops. The valve closure element comprises a thin, flexible sealing portion for engaging the vapor venting outlet with low sealing forces, and a stiffened marginal portion acted on by a rigid cage or frame which is connected to the float. As the float drops, the cage contacts the stiffened marginal portion and levers the valve element off the venting outlet.

  • Patent number: 6239562
    Abstract: A torque motor and engine throttle valve assembly employing same having an annular stator with a pair of semi-cylindrical shell permanent magnets disposed on the inner periphery of the stator. A pair of rotor pole segments each having an L-shaped configuration in section in the plane of symmetry have an arcuately shaped outer flange. The rotor pole segments are joined axially and oppositely disposed on the motor shaft to form an S-shape in section in the plane of symmetry. A stator coil is assembled with the pole segments on the rotor shaft, and the stator coil is attached to the stator through an open side of the S-shape. The arcuate flanges maximize the rotor material adjacent the radial flux gap between the magnets and the rotor pole segments. In the throttle valve, the rotor pole segments are mounted onto an extension of the throttle blade shaft and the stator is attached to the throttle body.

  • Patent number: 5925538
    Abstract: Vectors and recombinant bacteria for overproducing riboflavin, in which nucleic acid overproducing riboflavin biosynthetic proteins is introduced in the chromosome of the host organism, e.g. at multiple sites and in multiple copies per site. A rib operon having at least five genes is used to make such recombinant bacteria.

  • Patent number: 4759326
    Abstract: An air throttle for an internal combustion engine having a shaft mounted butterfly vane mounted for rotation in the engine charge air inlet. The butterfly vane and shaft have an idle air bleed slot therethrough with a tubular idle valve mounted over said shaft for concentric rotation thereabout. With the butterfly vane closed for idle mode running, the idle valve is rotated between set limits to control idle air flow and idle speed. Upon rotation of the idle valve beyond the set limits, the butterfly is progressively opened for off-idle mode running speed control.
