Abstract: A dispenser for dispensing a web from a roll of paper includes a housing and a cover connected thereto to provide access to the housing interior. The dispenser has mechanism for supporting a paper roll and a drive roller and tension roller operatively associated therewith which urges paper from the paper roll into contact with the drive roller for dispensing a length of paper from the paper roll. Actuator mechanism operates the drive roller and extends across substantially the entire housing at the bottom thereof. A roller frame assembly is mounted within the housing and carries the tension roller and a transfer roller. The transfer roller releasably holds the free end of a first paper roll while paper from the second roll is dispensed upon actuation of the actuator to rotate the drive roller.

Abstract: A detection device for testing gloves or other protective clothing or equipment for breakthrough by a contaminant includes a pad carrying a reagent which is responsive to the contaminant for producing a color change. A barrier layer covers the reverse side of the pad to prevent escape of chemicals therefrom and an adhesive strip is secured to the barrier layer for attachment of the pad either to the skin of the user or to the inside of the glove or other clothing so that the obverse side of the pad is adjacent to the inside of the glove. In one embodiment the pad is impregnated with the reagent which directly reacts with the contaminant to produce a color change. In another embodiment, plural reagents are carried respectively in separate regions of the pad and, after exposure to the contaminant, a carrier solvent is applied to the pad which brings the reagents into intimate contact for cooperation to produce the color change.

Abstract: A label printer includes a thermal print head assembly for printing pressure sensitive adhesive-backed labels spaced longitudinally on a web. The print head assembly includes a row of heater elements aligned transversely of the web path and movable toward and away from the web, the heater elements being biased against the web. Mechanical displacement of the print head assembly due to the passage of the leading and trailing edges of the labels beneath the heater elements is sensed by a piezoelectric sensor carried by the print head assembly to locate the printing on the labels with respect to the edges. The sensor may be mounted directly on a pivoting print head or may be mounted on a pivoting support or bracket which carries the print head. The print head assembly may be of the thermal printing or thermal transfer printing type. Both individual and stacked piezoelectric ceramic transducer elements are disclosed.

Metal inserts are respectively received in the driven and driving ends of the tool body, the inserts respectively defining openings for respectively mateably receiving associated driving and driven members, the inserts being disposed in the body so that no portion of the inserts projects outwardly beyond the exterior surface of the body. The inserts are preferably insert molded in the body, but may also be fixedly secured in pre-existing recesses in the ends of the body, as by press-fitting or bonding. In the latter case, the inserts are provided with anti-rotation outer surfaces which are non-circular in transverse cross-sectional shape.

Abstract: A wire dereeling assembly for the continuous removal of wire from adjacent reels of wire includes a frame assembly positioned above the reels and located substantially perpendicular to a centerline extending through the reel axis of each of the reels and a guide member slidably mounted to the frame member and operable between a first position substantially coaxial with the reel axis of one of the reels and a second position where the guide member is positioned substantially coaxial with the reel axis of the other adjacent reel.

Abstract: A driving tool, such as a screwdriver, has a handle with an injection-molded, relatively hard and rigid inner body, molded around a tool shank, the inner body having an elongated central portion with two end flanges extending laterally outwardly of the central portion around the entire periphery thereof, with the central portion having a peripheral groove formed therein adjacent to an end flange. An outer gripping body of a relatively soft and resilient material is injection molded around the inner body, surrounding said central portion of said inner body and filling said groove.

The system has a text-based display screen and selective input keys including software-definable keys respectively associated with different regions of the display screen and respectively associated therewith by indicia on the screen bezel. Memories are coupled to the control circuit for cooperation therewith to control the display of messages on the display screen and for defining functions performed by the software-definable keys in accordance with the corresponding messages displayed on the display screen.

Abstract: A method of producing a non-metal element or a metal or an alloy thereof from a halide or mixtures thereof. The halide or mixtures thereof are contacted with a stream of liquid alkali metal or alkaline earth metal or mixtures thereof in sufficient quantity to convert the halide to the non-metal or the metal or alloy and to maintain the temperature of the reactants at a temperature lower than the sintering temperature of the produced non-metal or metal or alloy. A continuous method is disclosed, particularly applicable to titanium.

Abstract: The invention relates to a method of manufacturing fasteners such as self-piercing rivets, self-piercing studs, plugs, inserts, etc.. In such method a blank is provided and said blank is subjected to a rolling process causing material of the blank to flow radially towards said central axis and axially so as to axially lengthen the blank, with said predetermined geometry of said finished fastener being formed by said rolling process. In addition, a mandrel can be used to precisely define the geometry of the fastener. Fasteners made by the method of the invention are much cheaper than fasteners made by conventional upsetting and extrusion processes. Furthermore, the fasteners made by the method of the invention generally have the advantage of superior grain flow and closer manufacturing tolerances.

The top coat composition may include an acrylic resin, an epoxy resin, a silicone release agent, a silicone resin and appropriate solvents. Each of the parts can be separately applied to the bakeware substrate and heated to form a release coating. In some cases, the top coat composition alone may only be applied if fabrication of the coated substrate will not be severe.

Abstract: A dynamometer includes a pair of vehicle wheel-engaging rolls coupled through a clutch to a passive power absorption unit which includes a flywheel and an eddy current brake. A lift between the rolls can raise the vehicle wheels out of engagement with the rolls without braking the rolls The lift cooperates with a frame for partially covering and protecting the access one of the vehicle rolls so that, when the lift is raised the vehicle can be driven off the dynamometer substantially without contact of the vehicle wheels with the access roll. The dynamometer is calibrated by using the vehicle wheels to accelerate and decelerate the rolls, with deceleration activating the clutch to decouple the flywheel, which is then used for a coast-down test.
