Abstract: A method of measuring camber in a sheet of metallic material comprises the steps of displacing the sheet between fixed guides in a plane perpendicular to the width of the sheet such that a point on a center of the sheet travels a predetermined distance, measuring the length of the sheet adjacent a first longitudinal edge thereof which moves past a datum line when the sheet is displaced the predetermined distance and generating a signal having a value A proportional to the length, measuring a length of the sheet adjacent to a second, opposite longitudinal edge which moves past the datum line when the sheet is displaced the predetermined distance and generating a signal having a value B proportional to the second edge length, and calculating camber at the first edge, expressed as a radius of curvature R.sub.C of the sheet, by the equation: ##EQU1## where W equals the width of the sheet.

Abstract: A sports glove which includes a glove body, a plurality of open-ended stub fingers, a palm portion made of a flexible material, a flexible strap attached at a fixed end thereof to the palm portion and having a free end fitted with loop material, and a patch of hook material attached to the stub fingers. The strap is looped about a sports implement to be grasped and the free end of the strap is attached to the glove body by the connection formed between the patches of hook and loop material. In use, the tensile force exerted by the implement on the hand of the user bears against the portion of the free end overlapping the hook material to form a secure attachment, so that a portion of the force is borne by the strap and glove palm. The hook and loop connection can be released quickly by the wearer of the glove and involves merely the straightening of the wearer's fingers.

Abstract: A syringe purging device comprises a closed chamber into which air and/or any excessive amount of a hazardous liquid, such as a chemotherapy drug, is ejected from a syringe to overcome the health hazard created by openly purging syringes into the air or into a pad of gauze material. A sharp open end of a hollow needle of a syringe is sealingly inserted into the chamber and the syringe is activated to purge any air and/or excess liquid into the chamber which expands as necessary. Preferably, the chamber is then further expanded to reduce the pressure therewithin to better ensure clean withdrawal of the needle from the chamber or extension of the needle beyond the chamber and retention within the chamber of any fluids ejected from the syringe.

Abstract: A developer sheet having reduced tack useful in forming reproductions having a controllable gloss finish or in forming transparencies is provided. The developer sheet has a support with a layer on the surface of the support of a finely divided thermoplastic developer material and a non-reactive, non-scattering pigment. The developer material is capable of reacting with a color precursor to produce a visible image while the pigment reduces tack. Both the developer material and the pigment are capable of forming an essentially transparent film upon the application of heat and/or pressure.

Abstract: A syringe purging device comprises a liquid-tight chamber into which air and/or any excessive amount of a hazardous liquid, such as a chemotherapy drug, is ejected from a syringe to overcome the health hazard created by openly purging syringes into the air or into a pad of gauze material. A sharp open end of a hollow needle of a syringe is sealingly inserted into the liquidtight chamber, and the syringe is activated to purge any air and/or excess liquid into the chamber. The liquidtight chamber may be closed, with any liquid ejected thereinto being retained by absorption into a wad of absorbent material contained within the chamber. Alternately, the chamber may be vented to the atmosphere through a hydrophobic filter such that air injected into the chamber passes through the filter, but any liquid is retained within the chamber since it cannot pass through the hydrophobic filter.

Abstract: A fire fighter helmet of the type having a body which includes a peripheral brim, an arcuate face shield having an inwardly extending lip and a flexible gasket on the underside of the lip for forming a watertight seal with the brim when the shield is in a down position, and a pair of hinges attached to opposite sides of the helmet body and pivotably attached to the face shield. The hinges each include a hinge plate and a spring which is connected at one end to the shield and at an opposite to the hinge plate rearwardly and below the pivot connection between the hinge plate and face shield. The hinge plate also includes a stop defining an upper limit of travel for the face shield. The spring urges the shield to pivot either to an up position against the stop, or to a down position in which the gasket forms a watertight seal with the adjacent portion of the helmet body brim.

Abstract: A method of tension leveling a continuous strip of nonhomogeneous metal sheet in which the yield strength of the strip edges is less than the yield strength of the center. The method includes the steps of unwinding the strip from a coil supported on an uncoiler, passing the strip through tension-generating bridle rolls and, while under tension is passed, in a serpentine path between upper and lower sets of nested work rolls and through tension relaxing bridle rolls, and rewinding the strip into a coil on a recoiler. The improvement consists of the additional step of, prior to passing the strip between the work rolls, heating the strip edges to a temperature above that of the center of the sheet to create thermal expansion in the edges sufficient to produce a thermal strain such that, when added to an elastic strain at yield in the edges, total strain is equal to an elastic strain at yield in the center of the sheet.
