  • Patent number: 9730456
    Abstract: A chain tensioning sprocket is moveable with a predetermined force into a U-shaped path of a chain to apply continuous tensioning force to the chain. The change in length of the chain is measured by detecting the movement of the chain tensioning sprocket into the U-shaped path of the chain, and measurement of movement of the chain tensioning sprocket indicates a change in the length of the whole chain, which, in turn, indicates the wear on the parts of the chain and the expected operative life of the chain.

  • Publication number: 20080104914
    Abstract: A resilient floor surface for indoor and outdoor, residential, commercial and sporting applications includes a resilient underpad formed of expanded polypropylene product (“EPP”) and suitable for being laid down directly on the ground or other subfloor surface in a floating arrangement not requiring securing to the ground or other subfloor surface, and a floor covering material applied upon the resilient underpad as a covering for the resilient underpad. The surface covering is of the type suitable for floor surfacings, sport playing surfacings and decorative and sports surface coatings, and is selected from hardwood flooring, synthetic rubber and/or plastic flooring tiles and panels, rubber flooring tiles and panels, laminated wood flooring, residential and commercial carpets, crumb rubber surface coatings, EPDM (ethylene-propylene terpolymer) surface coatings, polyurethane surface coatings and any other suitable coatings.

  • Patent number: 7161017
    Abstract: A process for producing unsaturated and saturated free fatty acid from trap oils, trap greases, brown greases and grease trap waste as starting material. The process consist in subjecting the starting material to a pretreatment, a first purification step, a fractional step, a second purification step and eventually a hydrogenation step. Methyl esters of unsaturated and saturated free fatty acids, oleic acid and stearin is obtained from this process.

  • Publication number: 20050043555
    Abstract: The present invention relates to a process for the production of unsaturated and saturated free fatty acids. The process comprises the steps of: (a) selecting a starting material from the group consisting of trap oils, trap greases, yellow greases and brown greases, (b) pre-treating the oils and/or greases selected in step (a) in order to separate the oils and/or greases, from residual solids and water and obtain a mixture consisting principally of saturated and unsaturated free fatty acids, (c) bleaching the mixture of free fatty acids obtained in step (b) in order to obtain a suitable coloration thereof, (d) fractionating the bleached free fatty acids obtained in step (c) in two fractions: saturated and unsaturated fatty acids, (e) purifying the unsaturated fatty acids obtained from step (d), and purifying the saturated fatty acids obtained from step (d).

  • Patent number: 6740387
    Abstract: A synthetic turf surface for golf courses, tennis courts and other grass-surfaced game playing fields is formed of a synthetic grass carpet having a flexible base sheet with closely spaced-apart upright, blade-like strands of plastic material forming a dense grass-like surface. The carpet is supported upon a cushioning underpad which is formed of a thick, molded sheet of open cell, expanded bead polypropylene. The resiliently compressible polypropylene underpad combined with the synthetic grass carpet closely simulates the feel of a natural grass covered playing field surface.

  • Patent number: 6602113
    Abstract: A method for forming a synthetic turf game-playing surface comprises, first, providing a pile carpet cover having a base sheet carrying closely spaced-apart, upright, grass-like plastic strands forming simulated grass blades. The cover is laid upon a resilient cushion pad supported upon a firm surface, and sand-like particular material is blasted against the upper portions of the blades at sufficient pressure and for sufficient time to shred the blade upper end portions into fine slivers which remain joined to their respective blades and become intertwined with adjacent slivers to form a dense mat upon the upper surface of the carpet. During the blasting, the resilient cushion beneath the carpet, resiliently supports the upright blades against being crushed or permanently compressed by the force of the blasting.

  • Patent number: 5373667
    Abstract: The synthetic turf has a base made of fabric material from which upwardly projects a mass of entangled, crimped grass-like frayed blades made of polypropylene, nylon or polyester. The blades have a length between 3/8" and 2", a weight from 28 to 60 ounces per square foot and a denier value of about 5400. The method of treating this synthetic turf consists in sandblasting the blades from above the turf at a distance of about 3 to 4 feet with a jet of sand having a pressure of about 80 to 120 pounds per square inch and directed at an angle of about 70.degree. to 80.degree. from the horizontal and in a circular motion. The border strip for an artificial golf practice course comprises a body made of polystyrene, a sheet of polypropylene applied over the body and a synthetic turf covering applied over the sheet of polypropylene. The body is shaped so that the synthetic turf covering form a ball rolling surface inclined or square with respect to a central playing surface.
