Abstract: An apparatus for decontaminating and destroying hypodermic syringes and needles includes a waste compression cylinder having a cylinder side wall and a closed cylinder abutment end wall, and having a cylinder waste receiving port in the cylinder side wall and a waste releasing port in the cylinder side wall; a waste compression piston slidably retained within the waste compression cylinder; a piston drive mechanism drivably connected to the waste compression piston for driving the piston away from the abutment end wall to open space for receiving waste within the compression cylinder and for driving the piston toward and into close proximity with the cylinder abutment end wall to crush needles; a decontaminating air blowing mechanism oriented to blow decontaminating air into the compression cylinder; and an air heating mechanism for heating the decontaminating air to a decontaminating temperature.

Abstract: An apparatus for sterilizing and destroying hypodermic syringes and needles includes a waste compression cylinder having a cylinder side wall and a closed cylinder abutment end wall, and having a cylinder waste receiving port in the cylinder side wall and a waste releasing port in the cylinder side wall; a waste compression piston slidably retained within the waste compression cylinder; a piston drive mechanism drivably connected to the waste compression piston for driving the piston away from the abutment end wall to open space for receiving waste within the compression cylinder and for driving the piston toward and into close proximity with the cylinder abutment end wall to crush needles; a sterilizing air blowing mechanism oriented to blow sterilizing air into the compression cylinder; and an air heating mechanism for heating the sterilizing air to a sterilizing temperature.

Abstract: A sealing apparatus for use with a door which swings over a threshold and has a door lower end, a door face and a door frame, for closing the gap between the door lower end and the threshold, includes a mechanism mounting member; a substantially horizontal gate member for closing the gap; a slide bar positioned above and substantially parallel with the gate member, the slide bar having a protruding end extending laterally from the door toward the door frame to abut the door frame as the door is closed; structure for guiding the slide bar to move laterally relative to the door and to the mounting member; a leaf spring having a leaf spring first end and a leaf spring second end and a leaf spring central segment, the leaf spring first end being engagingly fitted to the slide bar and the leaf spring second end being engagingly fitted to the gate member, where the leaf spring central segment is resiliently pivotable upwardly and laterally to vertically displace the gate member relative to the slide bar; structure

Abstract: A level apparatus for spanning two spaced apart building structure points and indicating whether the points are level relative to each other includes an elongate tubular segment having a tubular segment longitudinal abutment face for abutting a building structure point; an extension segment slidably retained within the tubular segment for slidingly extending partly out of the tubular segment and having an extension segment longitudinal abutment face for functionally extending the tubular segment longitudinal abutment face when the extension segment is extended; and a longitudinally oriented bubble site glass.

Abstract: A sealing apparatus for use with a door which swings over a threshold between an open position and a closed position and has a door lower end spaced above said threshold and defining a gap between the door lower end and the threshold when the door is in the closed position, and has a door face and a door frame includes a mechanism mounting member; a gate member for closing the gap; a leaf spring having a leaf spring first end and a leaf spring second end, the leaf spring first end being secured to the gate member with a securing structure, and the leaf spring second end being secured to the mounting member with an anchoring structure, where a segment of the leaf spring angles upwardly and laterally to form a spring cam surface; a structure for guiding the gate member to move up and down relative to the door; a cam engaging member positioned above and substantially parallel with the gate member, the cam engaging member having a protruding end extending laterally from the door toward the door frame to abut the

Abstract: A female electric cord plug or wall outlet is provided for fastening to a male electric cord plug having at least one prong, where the at least one prong has a longitudinal axis and at least one dent, including at least one prong receiving opening having a longitudinal axis along which the prong receiving opening receives the at least one prong, a prong engaging mechanism in the form of at least one dent engaging member which can enter the prong member can exit the prong receiving opening and disengage the dent and where the dent engaging member includes a shaft positioned essentially perpendicular to the longitudinal axis of the prong receiving opening and a cantilever structure having two ends and attached at one end to the shaft to protrude laterally from the shaft, the shaft being positioned to pass adjacent to the prong receiving opening, the shaft being slidable relative to the prong receiving opening such that the laterally protruding cantilever structure enters and exits the prong receiving opening to

Abstract: Method comprises positioning a spray gun and its cup-connecting means in a stationary support, and its gun cup in a rotatable cup holder in a closed chamber. Then, compressed air and cleaning liquid is passed through the gun and cup-connecting means, while simultaneously rotating the cup holder and spraying the exterior surfaces of the cup, gun, and cup-connecting means and the interior surfaces of the cup. In a preferred embodiment, the spray from the gun rotates the cup holder. The device comprises the chamber, the gun support, a rotatable cup holder, a pool for cleaning liquid, spraying means, internal means for filtering and distributing cleaning liquid to the cup connecting means and the spraying means, and means for introducing compressed air from outside the chamber into a compressed-air manifold and then distributing the compressed-air to the gun and spraying means. The device also includes means for venting air that is exhausting from the chamber and means for absorbing fumes in the exhausting air.

Abstract: A phosphorescent keyhole locator particularly adapted for use in combination with a tumbler-type lock comprising a cylindrical tumbler having a circular tumbler end surface with a keyhole therein, and a peripheral end surface around the tumbler end surface. A solid phosphorescent plastic body having an aperture therethrough is adhesively attached to the peripheral end surface with the aperture positioned over the tumbler end surface. The aperture is at least about as large as the tumbler end surface and has straight sides which may be normal to or bevelled towards the tumbler end surface.

Abstract: A tool having a pair of open-ended jaws with spaced confronting jaw faces and a support for the jaws, wherein each jaw comprises a continuous loop of chained links movably mounted on a plurality of rotatable rollers, said rollers being floatingly mounted on said support, each of said loops having a substantially straight segment that is spaced from and confronts the straight segment of the other of said loops, each link having a tread on the outer side of said loop, which tread aligns with the treads of the other links in said straight segments to constitute the confronting face of said jaw, and a ratchet means mounted on said support and adapted to push one of said loops to move in only one direction around its supporting rollers.
