Abstract: A window cover for a military vehicle which includes both upper and lower armored plates angled away from an underlying vehicle window. An upper and lower reflector are placed so that light striking the upper reflector is reflected onto the lower reflector. One of the reflectors is pivotable. The window cover allows an occupant of the vehicle to view outside the vehicle window, as light is reflected off an upper reflector to a lower reflector and toward an occupant of the vehicle. A filter is placed between the upper and lower reflectors to filter out a portion of light reflected. The filter may also provide a collimation function.

Abstract: A drinker system having a pressure regulator that receives water at its inlet and provides water at a predetermined pressure at its outlet. At least one drinker is connected to the outlet of the pressure regulator. The pressure regulator is moveable between a lower position and an upper position relative to the drinker. When the pressure regulator is moved to its upper position relative to the drinker, the drinker receives a higher pressure than the predetermined pressure at the outlet of the pressure regulator. The pressure regulator is connected to the drinker with a four bar linkage having a pair of bars that are substantially parallel to each other. Each of the bars is pivotally connected to the drinker at one end and the opposite ends of the bars are pivotally connected to the pressure regulator.

Abstract: A hinged vapor wall for use in mobile living quarters having a main living area and a secondary area such as a garage. The vapor wall has a first and second section that overlap to form a barrier between the garage and the main living area. When the sections of the vapor wall are in their closed position, the main living area and the garage area are divided into separate airtight compartments. Typically, small vehicles such as motorcycles and ATVs are placed in the garage, and the fumes from their fuel may spread into the main living space in the absence of a barrier. A permanent barrier sacrifices space within the main living area. The hinged vapor wall of this invention is movable to an open position when small vehicles are not being stored in the garage, enabling the garage to be used as living space as well.

Abstract: A method of detection of cells, microorganisms, or molecules by the use of various combinations of fluorogens and a chromogens which yield fluorophores and chromophores when cleaved by specific enzymes and which can be viewed by UV and visible light. Included is the method of application of a family of compounds producing both insoluble fluorophores and chromophores identified as dual enzyme substrates.

Abstract: Both the inner and outer circumferential surfaces of a coil spring are peened by passing sequential segments of the spring around offset pulleys mounted within a peening cabinet. As the spring is pulled around one of the pulleys, the coils fan out from the pulley to permit the peening media to impact portions of the inner and outer circumferential surfaces of the spring, and as the spring is pulled around the other pulley, the portions of the surfaces not peened as the segment traveled around the first pulley will be peened.

Abstract: Method, procedure, and device for applying tactile sensation and vibration to the human body. In this invention one or more vibrating elements emit sine waves between 20 and 800 Hz. These waves are varied in frequency, amplitude and rhythm to create in the subject the sensation of massage moving through different parts of the body even though the signal emitter may be a point source.

Abstract: A locking system for securing tools on an arbor. The locking system has a collar attached to the arbor, with the collar spaced from the tooling. A nut is placed over the collar and positioned next to the tools. The nut is then rotated to secure the nut between the collar and the tools.

Abstract: A filter made of specifically arranged filaments. The filter has an upstream side where fluid enters and a downstream side where fluid exits. The filaments are greatest in diameter near the upstream side wherein the filaments continuously and gradually decrease in thickness toward the downstream side. The pores or spaces between the filaments are largest near the upstream side and decrease gradually toward the downstream side. This allows various size particles to become entrained in the filter in an evenly distributed manner.

Abstract: An electromechanical travel bar lock assembly disables the flow of power to the power drive that moves a RV slide-out room between the traveling position and the deployed position. The assembly includes a bar for removably securing between the wall of the vehicle and the facer board of the slide-out room to prevent the room from moving. The travel bar is provided with an actuator that actuates, directly or indirectly, a switch means incorporated into the circuitry of the power drive so that power is not permitted to flow from its source to the drive, and the slide-out room cannot be moved when the travel bar is positioned between the vehicle wall and the facer board. The actuator, switch, and circuitry may embody any one of several different configurations and/or combinations.

Abstract: This invention relates to a liquid filter having a housing and a top. The housing includes an inwardly protruding annular shoulder which supports a filter basket. Forming a part of the housing and located above the annular shoulder is a tapered protrusion over which a filter bag is press fitted and snapped under so as to be suggested against the underlying annular shoulder.

Abstract: A spring wire retention device for a chair that includes a spring network with spring wires bridging an opening that defines a seat is disclosed. The spring wire retention device includes a retainer body with an abutment formed therein for preventing movement of the spring wire bridging the opening. A stop member is oppositely disposed from the abutment. Between the abutment and the stop member, a cavity is formed in the retainer body. A resilient member protrudes from within the cavity. The resilient member constantly urges the spring wire against the abutment. The invention may be cast in the form of a ring with a plurality of retainer bodies circumscribing the ring and supporting a spring network.

Abstract: A drop floor for a mobile home or a park model home creates additional space and headroom between the ceiling and floor. A home built according to the invention typically includes a frame supported upon an axle. The frame has numerous cross members extending between a pair of opposite side members and includes a first portion located at a first height with respect to the axle and a second portion located at a second height below the first height. A building structure is supported on the first and second frame portions. The invention includes a drop floor construction method where floor decking is attached to the second portion of the frame so that the floor decking is in contact with the frame and located at the second height, which is below the first height. The drop floor includes nailers, closure material and insulation so that the drop floor can rest upon the ground surface if desired.

Abstract: A frame member supports a seat and a back and is movable between a horizontal position for supporting a user thereon and a vertical position for stowing the frame against the wall. Linkage secures the frame member to a wall mounting apparatus. The linkage includes oppositely disposed pairs of links that pivot the frame member relative to the wall to define a first distance between the wall and the frame member when the frame is in the vertical position and a second lesser distance between the wall and the frame member when the frame is in the horizontal position thus requiring less space between the frame and the wall. The frame assembly also has a leg pivotally connected to the frame member by linkage such that the leg moves beneath the frame between an upstanding supporting position and a collapsed storage position coincident with movement of the frame.

Abstract: A fifth wheel coupling for coupling sections of a tractor-trailer articulated vehicle includes a main plate mounted on the tractor which defines a keyhole slot for receiving a kingpin mounted on the trailer. The keyhole slot terminates in a coupling aperture, and a locking mechanism movable between open and closed positions locks the kingpin in the aperture in the closed position to thereby couple the tractor and trailer together. A safety latch mounted in the keyhole slot is movable from an inactive position permitting the kingpin to move through the slot and into the aperture to an active position blocking the keyhole slot. An operating mechanism operates the locking mechanism and also moves the safety latch from the active to the inactive position to permit movement of the kingpin out of the keyhole slot when the tractor and trailer are uncoupled.

Abstract: A hydraulic lift for mobile living quarters having a liftable top. A fluid pressure source communicates fluid through fluid lines connected to a plurality of lifting members that extend upon receipt of fluid and retract upon discharging fluid. The rate at which fluid is discharged from the lifting members is a function of how much weight each lifting member bears. Each of the fluid lines has a flow control valve between the pressure source and each lifting member. Fluid is communicated through the flow control valve to the lifting member connected to the pressure source the fluid is also communicated through the flow control valve when fluid is discharged from the lifting member. The flow control valve limits the flow rate of the fluid to a constant predetermined rate when the fluid is discharged from the lifting member.
