  • Self adjusting energized valve seal
    Patent number: 5137259
    Abstract: A seal and seat for ball valves is a circular, elastomeric open torus which is fitted between the ball element and the housing. The open torus has within it, a substantially "v" shaped spring that is fitted within the "u" shaped opening of the torus. In normal operation, the spring member is slightly compressed between the ball and the housing and the ball can "float" between a pair of substantially similar seals on the input and output sides of the ball valve, respectively.

  • Method and apparatus for measuring the liquid level of a containment tank subject to external forces
    Patent number: 5133212
    Abstract: A detection system for determining the level of a liquid in a containment tank includes a containment tank and a reference standard of known weight mounted to the vehicle and movable along the yaw axis of the vehicle. Load cells are placed intermediate the tank and reference standard to provide analog voltage outputs in proportion to the load on each cell. The load cell outputs, when amplified, summed and then divided by the output of the reference weight load cell, provide an electronic signal that is proportional to the gross weight of the tank. A pre-set signal, representative of the empty weight of the tank, is subtracted from the gross weight signal, resulting in a signal which is proportional to the net weight, or the contents of the tank.

  • Modular view lens attachment for micro video imaging camera
    Patent number: 5124797
    Abstract: A micro video imaging camera has a detachable distal module which is replaceable with one of different characteristics (e.g., angled), and sterilizable. Thus a non-replaceable CCD and video transmitter are connected to an inner body which comprises in effect a lens tube. The module comprises an outer body encasing the inner body which has a filter (optional) at its tip and a magnifying lens optically connected to an image conduit optical segment. The inner body receives the image conduit, the output of which is focused by the lens in the inner body on a CCD microprocessor. The model may be replaced with an angular distal end or lenses of different fields of view. Fiber optic light filaments may be used to illuminate the field of view of the tip of the module, either housed internally or externally of the inner body.

  • Optical switch and color selection assembly
    Patent number: 5082354
    Abstract: An apparatus and method for providing optical switching or color selection capability uses cholesteric liquid crystals which reflect and transmit circularly polarized light and a variable wave retarder element together with phase reversing mirrors which recapture and recombine the reflected circularly polarized light. With the retarder element in a first state, first orientation circularly polarized light is completely transmitted and second orientation circularly polarized light is redirected. Alternatively, a color selection assembly is provided through the use of a combination of cholesteric light crystals in which light of a first color is given a first polarization orientation and light of a second color is given a second polarization orientation. Depending upon the state of the retarder either the first or second color is transmitted to a desired target.

  • Access port sealing device
    Patent number: 5056678
    Abstract: An access port cover is fitted with a sealing plug that is adapted to fit inside a conduit to provide an occluding seal. The conduit is also fitted with an inner flap that is automatically closed and latched when the cover is closed and latched. In a preferred embodiment, a ridge in the inner wall of the conduit cooperates with a support plate to compress the plug between the cover and the plate, extruding the plug radially into sealing engagement with the inner wall of the conduit.

  • Breakaway coupling
    Patent number: 5050911
    Abstract: A coupling device includes male and female telescoping members that are inserted into a fluid carrying hose or conduit. The coupling device includes an O-ring for providing fluid tight seal and a frangible locking ring that will separate when oppositely directed forces exceed a predetermined threshold. The locking ring includes a split so that it can be compressed to a smaller diameter for installation and, in the preferred embodiment, a plurality of frangible radial tabs. In an alternative embodiment, the ring may have a radially extending flange with a parting groove at the juncture of the ring and flange. One of the coupling device members includes a groove that holds the ring and the other member includes a groove that receives the radial tabs or flange.

  • Portable boot removable device attachable to heel
    Patent number: 5046650
    Abstract: A boot collar adapted to be attached to the end of a boot. The collar is generally U-shaped having an internal rib adapted to engage the land of the boot. In one embodiment, the collar has a boot removal arm with a first end pivotally mounted to the boot collar. The removal arm is normally biased in a stowed position and movable to a operable position. When in the second position, the removal arm provides a cantilever upon which force can be exerted to assist in removing the footwear from the foot. When in its normally biased stowed position it is disposed where it does not interfere with the wearing of the boot. In another embodiment, a mounting post having a rotatable spur is attached to the collar.

  • Drain pipe trap
    Patent number: 5038816
    Abstract: A removable drain trap assembly comprised of a clear plastic curved pipe member, a removable bottom closure member attached to the dip portion of the pipe member, and a gridlike member placed vertically within the dip portion of the bottom closure member. The gridlike member is placed along the vertical cross section of the assembly having maximum fluid flux to maximize object capture capacity. The gridlike member conforms to the cross sectional width of the dip portion and the bottom closure member to minimize fluid flow impedance. The bottom closure member is elongated and deepened to facilitate retention of smaller foreign objects which might pass through the gridlike member.

  • Method and apparatus for multi-color display
    Patent number: 4991941
    Abstract: A field sequential color shutter display system including a light source emitting light rays having substantially first and second different primary colors. First and second light polarizing filters are included. The filters are aligned in optical communication with the source. Each filter includes a color selective polarizing filter having substantially orthogonally oriented absorption axes. The first absorption axis of each light polarizing filter passes linearly polarized light of the first color and a uniform first polarization. The second absorption axis of each light polarizing filter passes linearly polarized light of both the first and second colors and a uniform second polarization. Variable optical retarding filters are disposed between the first and second light polarizing filters.

  • Video system for visualizing microsurgical images with enhanced depth of field
    Patent number: 4987488
    Abstract: A high resolution video camera is equipped with a multi focal lens. The optical system is adjusted to provide a depth of field so that objects remain in focus. A high resolution, large screen color video monitor provides a greatly magnified view of the surgical field, permitting a surgeon to perform procedures directly from the screen image. Low light levels can be permitted and multiple monitors can be employed. Images can be stored on a disc or VCR and individual frames can be printed for a permanent record.

  • Pony shoe refrigerator magnet
    Patent number: 4971278
    Abstract: A holding device includes a lever arm, a magnetic fulcrum and a frictional member which is held against a magnetizable surface with the frictional member normally in contact with the surface. Pivoting the lever arm about the fulcrum raises the frictional member out of contact with the surface so that objects can be securely placed under the lever arm. Releasing the free end of the lever arm causes the holding end to return to the magnetizable surface, securely holding any objects placed therebetween against the magnetizable surface.
