  • Patent number: 5732712
    Abstract: A sterile operating room video monitor and video monitor support device are provided to enable a surgeon to more easily conduct endoscopic procedures. A lightweight self-contained monitor module is provided to enable the surgeon to easily manipulate the image on the video monitor of a surgical area. A video support stand which secures the video monitor in the sterile operating field allows a surgeon to precisely place the video monitor at a desired position. The video support stand includes a monitor mount which may have a plurality of apertures communicating with a source of vacuum to hold a sterile drape tightly over the monitor module screen. Alternatively, the drape may be eliminated, and a close tolerance fit is made between the monitor mount and video monitor securing it in the sterile field. This invention allows positioning of the video monitor in the natural line of sight of the surgeon as he or she performs an endoscopic procedure.

  • Patent number: 5722512
    Abstract: The shipping stand includes a cradle assembly mounted upon a frame assembly to which a jet aircraft is securable. The frame assembly includes a plurality of wheels for locomotive capability. A plurality of shock absorbers are operatively engaged between the cradle assembly and frame assembly to provide adequate shock protection to a loaded jet aircraft engine when the shipping stand is configured in a truck transport mode. A plurality of lifting mechanisms selectively raise the cradle assembly to a predetermined height creating gaps between upper transport flanges and lower transport flanges. The gaps correspond to the height of spacers positionable between the flanges in the truck transport mode. To place the shipping stand in an air transport mode, the lifting mechanisms are activated, the spacers are removed from between the flanges and the cradle assembly is lowered to eliminate the gaps between the flanges.

  • Patent number: 5720844
    Abstract: A floor covering removal apparatus and method are provided. The apparatus includes a frame for supporting the apparatus and a pair of interlocking gears which selectively and controllably feed a desired width of floor covering through the apparatus. One of the gears is driven by a drive which causes the apparatus to displace over a floor surface as the floor covering is fed through the apparatus. Cutting blades are mounted to the frame which cut the floor covering prior to engaging with the interlocking gears. A locking handle is provided to positively lock the floor covering between the interlocking gears prior to displacement of the apparatus along the floor surface. A control assembly enables an operator to selectively control the direction in which the apparatus is displaced.

  • Patent number: 5679162
    Abstract: An apparatus applies dressing fluid to a bowling lane surface in a discrete pattern laterally across a plurality of zones on the bowling lane. A carriage, for movement along a bowling lane, has an applicator mounted thereon for applying the dressing fluid to the bowling lane surface. Dressing fluid is supplied from a reservoir by a plurality of pulse valves which supply the dressing fluid to a plurality of fluid dispersion chambers, each having an inlet connected to one of the pulse valves and having an outlet positioned to apply dressing fluid to the applicator. The outlet has a width equal to the width of one of the zones. A controller is provided for selectively activating each of the pulse valves to discharge a discrete amount of fluid dressing into each dispersion chamber. Each zone may be the width of one board across the bowling alley so that different discrete amounts of oil can be applied to each board.

  • Patent number: 5656063
    Abstract: An air cleaner with separate ozone gas and ionized air outputs, and method of purifying air is provided. The air cleaner includes an exterior housing which houses an ozone generator component and a ionized air generator component. In operation, air is drawn through the air cleaner by means of a blower and is first passed through a multi-layered filter. The air then passes through an ionizer which ionizes the air and induces on it a net negative electric charge. As the ionized air is recirculated back into the device, the negatively charged air is electrostatically precipitated by the filter which maintains a net positive electric charge. The ozone generator component within the housing draws in air via an air pump which produces an output of pressurized air to the ozone generator. Within a mixing chamber of the ozone generator, the pressurized air is mixed with ozone produced therein and is then output through an independent ozone outlet tube.

  • Patent number: 5653403
    Abstract: In a first embodiment, the toilet paper holder and dispenser includes a rod receiving section adapted to receive the dispenser rod of a common toilet paper dispenser. A peg attaches to the rod receiving section and protrudes away therefrom. A stabilizer is also attached to the rod receiving section to prevent the toilet paper holder from undesirably rotating and shifting when toilet paper is dispensed from the roll which is mounted over the peg. In a second embodiment, the peg may be adjustably positioned at a desired vertical angle. In a third embodiment, the toilet paper holder includes a recessed mounting bracket which is directly mountable to the recess formed in the wall which previously had mounted to it the common toilet paper dispenser. For any one of the embodiments, the distal end of the peg may include either a tip portion which is angled or bent away from the longitudinal axis of the peg or may include a retainer or cap to assist in retaining a roll of toilet paper mounted over the peg.

  • Patent number: 5645389
    Abstract: A fan shipping frame includes a frame assembly for supporting a loaded fan section of a jet aircraft engine. A plurality of caster assemblies attached to the shipping frame provide locomotive capability and adjustable height positioning so that a loaded fan section may be transferred onto the appropriate transport aircraft or vehicle. Rail members mounted on the frame assembly are alignable with rail members of a fan dolly so that the fan section may be directly transferred from the fan dolly onto the shipping frame. A template bracket integral with the shipping frame enables the fan section to be mounted thereon. A platform assembly rotatably mounted to the shipping frame may be deployed to enable the fan section to be tilted from a vertical transport position to a horizontal transport position wherein, the shipping frame may be transported in either position. A storage container mounted on the shipping frame stores the removed fan blades of the fan section in either position.

  • Patent number: 5639936
    Abstract: A method and apparatus for decontaminating in-situ soil by use of solar energy is provided. A targeted area of contaminated in-situ soil is covered with a substantially sunlight-transmitting, nonporous covering that allows solar energy to penetrate said covering. A greenhouse effect subsequently occurs in which trapped solar energy heats the interior air within the covering and in-situ soil below the covering. As the in-situ soil is heated, contaminants found within the in-situ soil are vaporized. The structure comprises first and second side panels with attached first and second end panels. An exhaust vent is provided such that vaporized contaminants and air can escape the interior of the covering. An evacuating device can be utilized to further assist in removal of vaporized contaminants and air within the covering. A fresh air intake mechanism allows replenishment of air that is evacuated or vented with vaporized contaminants.

  • Patent number: 5633203
    Abstract: A miniaturized electronic imaging chip has stratified layers wherein a base silicon layer has a peripheral edge defining an area and a thickness which allows passage therethrough of most UV, visible and IR light. A pixel layer is formed on the back side of this first silicon layer. At least one interconnect layer is bonded to the pixel layer. Electric leads are bump bonded to the bonding pads on the outermost interconnect layer and extend away from it within the area for attachment to means for sensing electrical signals generated by an image projected onto the pixel layer through the silicon layer. Preferably, the leads are perpendicular to the chip. A unique method of manufacturing the miniaturized electronic imaging chip from a standard CCD comprises the steps of shaving a silicon layer, having a peripheral edge defining a second area which is smaller than the first area, on the back side of the standard CCD to a thickness which allows passage of a light image therethrough.
