Abstract: A computer-assisted method of graphically displaying one or more trailer load patterns for rolls of paper such that the load upon each axle of the trailer and corresponding tractor is maximized within physical and legal limits.

Abstract: The invention relates to a safety blood collecting device adapted to prevent accidental puncturing of attending medical personnel by an infected blood collecting needle. The blood collecting device has a forward conical portion which is provided with a vein aligning groove to allow convenient positioning of the needle guard in relation to the vein of the patient for precise injection of the needle. One or more resilient depressible locking tabs are carried by the needle guard and extend through corresponding aligned openings formed in the casing to lock the needle guard in an extended position covering the needle. When the locking tabs are depressed and an inward pressure is exerted on the forward end of the needle guard, the needle guard can be moved against the tension of a coil spring inside the casing and uncover the blood collecting needle to allow withdrawing of the blood from the patient.

Abstract: The invention relates to a safety syringe to prevent accidental puncturing of attending medical personnel by an infected syringe needle. The safety syringe has an elongated tubular casing, which houses an elongated needle guard, which is telescopically connected to the casing and is mounted in co-axial alignment with the casing. A syringe barrel is co-axially mounted within the needle guard, the syringe barrel carrying a needle assembly on one of its ends, and an end plate on its opposite end. The end plate "snaps" into a groove formed in a transverse flange of the casing, fixedly attaching the syringe barrel to the casing. A sealing plate covers the locked end plate by engaging within another groove formed in the flange. One or more resilient depressible locking tabs are carried by the needle guard and extend through corresponding aligned openings formed in the casing to lock the needle guard in an extended position covering the needle.

Abstract: The invention relates to a safety syringe to prevent accidental puncture of attending medical personnel by an infected syringe needle. The safety syringe has an elongated tubular casing which receives the needle guard in a telescopical relationship thereto. At least on locking tab attached to the exterior of the needle guard extends outwardly through an opening formed in the casing, such that depression of the locking tab allows telescopical movement of the needle guard inwardly into the casing. A tension member retains the needle guard in its fully extended position unless the tension of the member is overcome by compression of the needle guard during injection or the drawing of a medicine. The tension member can be in the form of a coil spring surrounding the syringe barrel and urging against the needle guard and the flange plate of the casing, or in the form of an elastic resilient member attached under tension between the needle guard and the casing.

Abstract: Heat curable adhesive compositions which include liquid polybutadiene polymer, powdered sulfur, organic accelerators and inert fillers are improved by adding blocked polyisocyanates or capped polyisocyanates. The addition improves resistance to "popping" of the cured or uncured adhesive when exposed to high temperature, e.g., spot-welding. The addition does not alter the beneficial flow properties and rheological properties of the adhesive. The adhesive is particularly useful on zinc coated steel, both electroplated zinc and hot-dip galvanized zinc coatings. Inclusion of zinc borate will activate the cure accelerators and retard the "popping" phenomenon at welding temperature.

Abstract: The surface of a basketball is provided with rows of pebbles or projections, each of which has a flat triangular outer surface and three pointed apexes. The triangles in each row are arranged in alternating directions so that the fingers of a player will engage the pointed apexes of some triangles regardless of the direction in which the fingers extend.

Abstract: A self-lubricating plug insert-type valve assembly is provided for use with inflatable articles of manufacture, such as footballs, basketballs, etc. The sealing plug through which the inflation needle is inserted is characterized by containing 3-12 parts by weight of a silicone grease for each 100 parts of rubber contained therein. Although contained as part of the rubber mix of the cured plug, the grease migrates within the plug and forms a continually renewed lubricant coating along the passage through which the needle is inserted and withdrawn.

Abstract: The invention relates to methods of manufacturing bladders for footballs comprising (a) applying a thin layer of coating solution to a polyurethane film, said solution consisting of polyvinylidene, ethylene vinyl alcohol, polyamide polymers or vinylidene chloride copolymers, and organic solvents; (b) evaporating said solvents; (c) optionally repeating steps (a) and (b); (d) forming said coated film into a bladder. Said invention also relates to products of said methods.
