Abstract: The present invention is an apparatus for identifying dental x-ray films that allows a health practitioner or staff member to permanently emboss indentifying indicia directly on to a patient's x-ray films. The device is portable and lightweight. Constructed from a plastic or PVC material, it is impervious to x-ray film fixer or developer, as well as the emulsion used on x-ray film. The device is unique in that it neither etches nor destroys the emulsion on the x-ray film.

Abstract: A punching tool for producing weep holes in a sill can utilized for window installations is disclosed. The tool has pivotally mounted jaws operable by a handle assembly with a punch formed flush with an end of a first jaw and a die opening provided in an end of a opposed second jaw. The pivotal connection of the jaws maintains the punch and die opening in arcuate alignment as the jaws are pivoted. A throat of the tool receives the upstanding leg of the sill can with the formed punch fitting flush against the bottom of the sill can and thus the tool will produce a weep hole in the upstanding leg flush with the interior bottom of the sill can as the jaws are pivoted toward each other. A large surface area surrounding the die opening in the second jaw prevents marring of the sill can exterior surface.

Abstract: A hand-operated canister opener tool, and method, for opening a frangible, plastic-walled, hollow canister (such as one containing a cryptographic, secret, military code) having two pivotally connected elements carrying a canister piercing member for piercing the canister to examine its contents before discard, and a canister receiving member surrounding the canister for safety during piercing for preventing ejection of shrapnel-like, sharp, plastic chips likely to cause bodily injury.

Abstract: A punch tool provides two generally longitudinal handles joined by a transverse pivot pin that is carried in a resilient bushing. One of the handles defines a straight bore that houses a sliding punch die and further defines a support for a mating, stationary die. The second handle is joined to the sliding die such that relative movement between the handles causes the sliding die to move within the bore, toward or away from the stationary die. Flexibility of the bushing permits the pivot pin to shift its axis longitudinally of the tool while permitting straight movement of the sliding die.

Abstract: A locking hole punch for punching holes in metal sheets, particularly metal sheets difficult of access such as metal C-studs, is disclosed. This hole punch comprises an arm member that has a head at the end of an outwardly curved portion and a first handle extending from that curved portion. A first lever member formed in a generally mating outwardly curved configuration is pivotably connected to the arm at the top of the arm handle at a first pivot. A generally straight second lever, which acts as a second handle spaced from the arm handle, is pivotably connected to the first lever member at a second pivot near the first pivot. A toggle member is connected to the second lever at a third pivot and to the arm handle at a fourth pivot. When the arm and second handles are pressed together, the toggle member is driven so that the second, third, and fourth pivots are moved into a straightline alignment so that the punch, which includes a punching pin, is driven into a working position with the head.

Abstract: After the removal of a burned out fluorescent lighting tube and its transport to a waste collecting locale, a hand held and hand operated tool is inserted in part over a tube end. Thereafter upon creating a squeezing force, via the lever action of this tool, a sharp pointed cutter is safely driven through the glass of the tube. A small vent hole is created, through which air passes until the outside and inside air pressures are the same. Thereafter, the tube is safely and progressively hit against the rim of a waste container to break the tube into small waste pieces, which drop into this container. In a preferred embodiment, two lever portions of a hand width length, are hinged at their leading ends, which are sized to fit over and partially down the end of the fluorescent lighting tube. A sharp pointed cutter is set back a short distance from the leading edge of one lever portion and positioned within an internally threadable upright embossment.

Abstract: A hand operated crimping tool comprising a crimping head 10 and a pair of operating handles 12 for actuating said crimping head. At least one of said handles includes a force sensing arrangement including detent mechanism for maintaining handle portions 80, 88 in an unloaded position until a predetermined crimping force is applied by the crimping head whereupon the detent mechanism releases to allow slight, relative pivotal motion between the handle portions. The detent arrangement includes a tapered extension post 90 defining a recess 100 and a grip 80 pivotally connected to the post. The grip slidably mounts a spring biased slider 98 which defines a recess, confrontingly aligned with the recess in the tapered post when the grip and extension are in an unloaded position. A detent ball 94 is captured between the confronting recesses. The force exerted by the slider on the detent ball resists pivotal movement between the grip and the extension.

Guides on the tool and die means permit alignment of the tool with a selected conductor while grooves on the die means prevent unwanted cable movement.

Abstract: A tool is provided for perforating a clamping band or the like of the type which has a plurality of evenly spaced apertures for accommodating connection of the band with barb members on clamp locking apparatus. The perforating tool includes a pair of levers pivotally connected for movement about a common axis and including plier-like manually engageable handles protruding from the common pivot axis. At the opposite side of the common pivot axis from the handles, the levers pivotally support respective rigid perforating tool blocks. One of these perforating tool blocks carries a male perforating plunger and the other of these blocks includes an opening for linearly guiding the plunger, as well as a support for a band being perforated. In order to accommodate linear movement of the plunger and guide opening during pivotal movement of the handle levers, the perforating tool blocks are guided at respective guide pins extending through the respective levers.
