Abstract: The present invention relates to provided a textile film lamination for use as a wall covering and the like, comprising a fabric layer formed of fire retardant yarn filaments and having a face and back side, a thermoplastic cap film applied to the face of the fabric under heat and pressure, a fire retardant thermosetting or thermoplastic film adhesive on the back of the fabric wherein the fabric retains its fabric-like quality in appearance and tactile feel. The invention retains a weave like look and feel to the fabric while providing a protective clear film on the face surface of the fabric. The invention is suitable for use on wall surfaces in aircraft interiors, rail coach cars, buses, ships, hospitals, public office buildings, sports arenas, hotels, theaters, churches, seniors homes and schools where flammability of the covering material is crucial.

Abstract: The present invention provides a textured tile for embedment in fresh concrete on a platform or walking surface comprising a generally planer element with an upper surface and a lower surface, said upper surface having a plurality of upper projections therefrom to provide a distinctive texture relative to the surface of the platform or walkway, said tile having two opposite side edges intended for alignment with corresponding side edges of other tiles, front and rear edges at least one of which faces oncoming pedestrian traffic. Vertical depending flanges are provided along said opposite side edges and said front and rear edges. There is a plurality of holes in said depending flanges and a series of projections depending from the lower surface of the generally planer element.

Abstract: The present invention relates to improvements in devices for use as grinding cups for grinding the hard metal pins or working tips of drill bits and more specifically, but not exclusively, for grinding the tungsten carbide cutting teeth or buttons of a drilling head and the means for detachably connecting the grinding cups to the grinding machine. The grinding cups have top and bottom surfaces and consist of a lower grinding section and an upper body section. The grinding section is formed from a material capable of grinding the tungsten carbide button bits such as a metal and diamond matrix. The peripheral edge in the bottom surface may be bevelled to facilitate the removal of steel from the face of the bit around the base of the button during grinding. A centrally disposed convex recess is formed in the bottom surface of the lower grinding section having the desired profile for the button to be ground. The upper body section has a centrally disposed cavity formed in the top surface of the grinding cup.

Abstract: The present invention relates to an apparatus to provide a secure connection between the male plug and female receptacle on adjoining electrical cords which prevents the plug from separating from the receptacle by forcing the plug and the receptacle together. The apparatus comprises a pair of opposing body portions, each of said body portions having an interior and an exterior end. The body portions preferably consist of a pair of co-axial cones with generally flat opposing bases. A centrally disposed longitudinal conduit is provided through said body potions and opens on said interior and exterior ends of said body portions. Elastic means link said body portions so that said body portions are biased towards each other when said elastic means is stretched to separate the body potions. The elastic means preferably comprise a plurality of lining members attaching the interior ends of said body portions.

Abstract: The present invention relates to a tailbone cushion to eliminate discomfort of patients afflicted with hemorrhoids, fissure, damaged coccyges (tailbone) or the like associated with sitting on hard surfaces. The tail bone cushion of the present invention consists of a cushion section having front, rear and side edges and generally flat top and bottom surfaces. The cushion section has a cutout centrally disposed in the rear edge providing said cushion section with a U-shaped configuration. The cutout is sized and located to eliminate contact between the patient's tailbone and either the cushion or the surface underneath the cushion. The cushion section is preferably tapered in thickness and firmness from rear to front. The cushion section is also preferably formed from a casing filled with a material that has low compression under a patient's body weight yet soft enough to permit sitting for extended periods with minimal discomfort. The tail bone cushion is optionally provided with a back support.

Abstract: A method for dehalogenating contaminated ground water and/or soil where the contaminated area is contacted with a titanium carboxylic acid derivative such as titanium oxalate, titanium citrate or titanium nitriloacetate and a corrin or porphyrin catalyst preferably vitamin B12 compound. The result of contact with the contaminated source is that the compounds reductively dehalogenate the contaminates thereby making it less toxic. This is achieved by making use of the non-toxic reagents, namely the corrin or porphyrin catalyst such as vitamin B12 and the titanium carboxylic acid derivative.

Abstract: The present invention provides an improved floatation support comprising one or more buoyant flexible foam tubes having first and second ends. A sling having first and second sides is connected to the first and second ends of the foam tube(s) so that they may be retained in a U-shape so that a person can lie or sit on the sling. The sling is attached to the foam tube in such a way as to pull the two ends of the tube together. This creates a comfortable platform on which a person can lie down either in the supine or prone position, typically with the head at the "U" bend in the tube and resting around the middle of the U Bend. The U bend provides means to support the head in the water, as this is the point of greatest buoyancy. The weight of the person on the sling is distributed evenly across the sling with the foam tube on both sides, resulting in good floatation characteristics and stability. A low center of gravity results because the weight of the user pulls down the center of the sling.

Abstract: The present invention relates to educational and demonstration devices for the instruction of basic scientific principles. The present invention consists of a kit for science instruction which comprises a multifunctional support block, activity cards containing directions for setting up and conducting experiements and a selection of accessory items. The accessory items can include gears, mirrors, ramps, dowelling, magnets, metal rods, weights, balloons, paper clips, string, tape, tacks, rubber bands, washers, straws, pins, moulds and cloth patches.
