Abstract: A spotter system is disclosed herein for assisting a weightlifter to safely exert a maximum effort during a weightlifting procedure. The system includes a frame for removably supporting a weight arrangement comprised of either free or track weights. The frame further supports a pneumatic lift which includes cables secured at one end to the barbell and at their opposite ends to a pulley. Via a chain drive from the pulley, an intermediate wheel is moved which, in turn, pivots a lever arm. The lever arm is attached at one end to a piston and cylinder assembly that offers less resistence to the users exerted effort to raise the barbell. Control of the resistence is effected by body limb activation of positive or negative switches coupled to the piston and cylinder assembly which further includes an air compressor, gages and relief valves.

Abstract: A dispenser is disclosed herein having a paste container removably mounted in a stationary base with a dispensing nozzle for discharging paste therethrough.

Preferably, the contour, color and overall shape of the replacement seat and back conforms with the contour, color and overall shape of the existing chair.

Abstract: An adapter for mounting a depth gage onto a mill head of a milling machine is disclosed herein having an elongated mounting bracket with an outwardly projecting block for slidably carrying an indicator rod with spaced apart depth V grooves thereon. The block has a viewing hole for visual observation of the V grooves and an adjustment screw retains the rod at a selected location on the rod. An adjustable anvil is carried on the rod below the markings and has a broad, flat surface cantilevered outwardly beyond the rod and its mounting block so as to receive engagement with the sensing probe of a conventional depth gage mounted on the machine.

Abstract: A dry insect extermination device is disclosed herein having box-like housing interiorly supporting an inner frame in spaced relationship to the walls of the housing defining an air conducting passageway between apertures in the housing sidewall and apertures in the frame bottom. The frame supports a heater and a fan for drawing heated air past chemically impregnated packs so that a dry chemical vapor is dispensed from the housing for distribution into the surrounding atmosphere.

Abstract: A medical instrument as a forcep with tissue-gripping jaws is disclosed herein having pivotal handles carried on an instrument body from which an elongated tube projects enclosing a push-pull rod. The rod carries a pivotal jaw arrangement and outwardly projecting from the tube for tissue grasping or gripping purposes. The other end of the rod is coupled to the handle for actuation of the jaw arrangement by either push rod or pull rod functioning. A spherical piston or rack and pinion gear interconnects the rod end with the jaw arrangement and a rod travel limit stop is operably connected between the handle, rod and instrument body. The jaw arrangement includes a pair of members having opposing wavy and serrated surfaces operably to open and close to retain tissue as the instrument is manipulated by medical personnel.

Abstract: A display apparatus is disclosed herein for dispensing a quantity of literature sheets or brochures stored in an ordered stack so that a portion of the uppermost piece of literature is visually displayed. Mechanism is provided for advancing the stack of literature within a housing so that the uppermost piece of literature bears against an advancement mechanism including rollers which advances the uppermost piece of literature so as to be partially exposed externally of a dispensing slot whereby a user may readily grasp the exposed portion and withdraw the literature. The stack of literature is carried on a spring-biased platform normally urging the stack upward against the underside of the advancement mechanism. An adjustable tension and system maintains the platform in a centered disposition with respect to the storage housing.

Abstract: An air freshener device is disclosed herein in combination with a forced air source and which has a carrier with a plurality of fragrance or scented emitting ingredients or the like arranged in separate spaced-apart cells or compartments in rows and/or columns. The carrier includes breakable walls for each cell or compartment adapted to release the stored ingredient into a stream of oncoming forced air. Attachment elements secure the carrier to supporting structure so that released ingredient will enter the stream of forced air for distribution throughout a room.

Abstract: A reclosable cover is disclosed herein for temporarily sealing and covering the open top of a beverage can which includes a cover body or disc having a downwardly depending peripheral flange with a connecting hinge secured to the sidewall of the beverage can. The cover body includes a circular recess adjacent to the flange adapted to permit nesting or stacking with the bottom of another can. The cover body further includes a weakened portion permitting the passage of a straw. The flange terminates in an inwardly disposed end portion for tightly sealing with the can and also provides for releasable retention of the body cover with the can.

Abstract: A sight barrier or screen is disclosed herein for temporarily obstructing oncoming motorists' view from accident scenes which includes an elongated screen or shield having a stowed position deployable into an operative position by inflation of tubular or conduit members. A main or base conduit is included having outwardly projected leg members for supporting the screen or shield in the operative position and further having upwardly projecting stanchions in spaced-apart relationship supporting a plurality of sight barriers therebetween. A source of pressurized gas is operably connected to the main base conduit for rapid deployment of the shield into its operative position and ground engaging or retention devices are included for holding the shield in place at the accident site.

Abstract: A foot-operated control for adjusting a water faucet valve mechanism is disclosed herein having a turning mechanism coupled to a faucet valve in a water line responsive to a foot pedal or treadle for selectively opening and closing the valve to control the flow of water therethrough. Examples of a turning mechanism may be a looped cord about a drum or a lever arm attached to the valve, either of which is operated by a push rod or cable actuated by the foot pedal or treadle.

Abstract: A fire prevention system is disclosed herein for external installation on a dwelling having an extended conduit closed at one end and detachably coupled to a source of pressurized water at its opposite end. A portion of the conduit is disposed along the highest part of the roof and is provided with a plurality of spaced-apart fluid discharge nozzles such as sprinklers. A smoke detector and sprinkler activator is operably connected to the conduit and is critically mounted on the exterior of the dwelling on the side thereof most likely to detect the presence of smoke. The windward side is an example. The activator includes solenoid operated valves responsive to the detector and further, a deactivate circuit is operably included for automatic shut-off.

Abstract: A decontamination treatment of process water is disclosed herein originating from electroplating/metal finishing and etching operations wherein the process water is loaded with heavy metal ions. The inventive process combines predetermined quantities of alkali/acid solutions together with a quantity of Sodium Humate so as to produce a disposable sludge which is environmentally safe and poses the least risk for leeching of harmful metals from the resultant sludge.

Abstract: A tie-down apparatus is disclosed herein having a composite overlying double track on which a car is slideably carried on the topmost track and securement fasteners carried in the lowermost track secure the double track to a supporting rail or truck bed. The car includes a spring-biased plunger having an enlarged head adapted to ride in the uppermost track during positioning of the car along its linear length and to seat in a selected one of a plurality of notches in the rails of the uppermost track for releasably retaining the car in the selected location. The plunger mounts a rotatable ring latch having a first position bearing against the car to prevent displacement of the plunger head from the selected notch and a second position in alignment with lateral car recesses to permit displacement of the head from the selected notch against spring expansion pressure to free the car for sliding along the track.
