  • Patent number: 5971440
    Abstract: A pipe is assembled from sections of a liner pipe formed of a moulded glass reinforced plastics material (GRP). A sleeve, also of moulded GRP, sealingly surrounds the joint between the sections. An outer pipe of polymer concrete is formed in sections on the liner pipe sections to surround the latter together with the sleeve. The sections have a packer provided between adjacent ends, and the joint is offset from the joint between the liner pipe sections. The GRP of the liner pipe can withstand high chemical concentrations in toxic sewage, the sleeve preventing seepage of sewage and being able to withstand chemical attach by any passing through the inner joint. The polymer concrete enables the pipe to withstand jacking forces, and is also resistant to chemical attack from a basically saline surrounding soil.

  • Patent number: 5972148
    Abstract: A process for applying a removable and releasible protective layer over an adhesive surface of a flexible sheet flooring product while simultaneously collecting the flooring product on a core roll. The process includes the steps of attaching a leading end of the protective layer to the core roll, and attaching a leading end of the flooring product to the core roll. The flooring product is oriented such that the adhesive surface faces inwardly towards the core roll and adjacent the protective layer. The core roll is then rotated such that the protective layer is applied to and overlies the adhesive surface of the flooring product as the flooring product is simultaneously collected on the core roll.

  • Patent number: 5964108
    Abstract: A high security lock includes a housing defining an interior chamber having a longitudinal chamber axis and a keyway axially through the housing into the chamber. A cam arrangement within the chamber defines an access in axial alignment with the keyway. The cam arrangement includes a plurality of stationary raceway cams arranged in parallel planes and concentric to the chamber axis. Each raceway cam has a radially-inward surface forming a bearing raceway. The cam arrangement further includes at least one stationary locking cam arranged in a plane parallel to the raceway cams and concentric to the chamber axis. The locking cam has no such bearing raceway. A tumbler assembly is disposed within the chamber and cooperates with the cam arrangement for selective rotational movement within the access about the chamber axis. The tumbler assembly includes a plurality of bearing elements supported for axial movement relative to the cam arrangement.

  • Patent number: 5957871
    Abstract: An ankle splint product includes an ankle splint for being custom-formed to the shape of an ankle while flexible and upon hardening providing a rigid, supporting custom fit. The ankle splint product includes an outer container formed of moisture-impervious material, and first and second flexible ankle splint segments positioned in the container in substantially moisture-free conditions and sealed therein against entry of moisture until use. Each of the first and second ankle splint segments includes an elongate substrate and a reactive system impregnated into or coated onto the substrate. The system remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to moisture to form a rigid, self supporting structure. An elongate, flexible protective pad is positioned on one side of the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the ankle splint is in use.

  • Patent number: 5952078
    Abstract: An athletic guard shaped to fit against a body part is provided for protecting the body part from injury. The athletic guard includes an energy absorbing laminate structure. The laminate structure includes a first array of high performance, unidirectionally-oriented fiber bundles. A second array of high performance, unidirectionally-oriented fiber bundles are cross-plied at an angle with respect to the first array of fiber bundles, and laminated to the first array of fiber bundles in the absence of adhesives or bonding agents. First and second polymeric films are bonded to outer surfaces of the laminated first and second arrays of unidirectional fiber bundles without penetration of the films into the fiber bundles or through the laminate from one side to the other. A sufficient amount of film resides between the laminated first and second arrays of unidirectional fiber bundles to adhere the first and second arrays of fiber bundles together to form the laminate structure.

  • Patent number: 5935668
    Abstract: A wooden flooring strip having a top surface having a decorative finish and a base surface opposed to said top surface. The base surface has a multiplicity of closely spaced-apart scores extending into the flooring strip from the base surface transverse to the length of the flooring strip along substantially the entire length of the flooring strip to relieve stress and increase flexibility in the wood strip for more closely adhering to irregularities of a sub-floor. The flooring strip has substantially longitudinally-extending wood fibers in an area of the flooring strip between the scores and the top surface of the flooring strip which have been broken to an extent sufficient to relieve tension on the top surface of the flooring strip and to equalize tension on the wood fibers adjacent both the top surface and base surface of the flooring strip.
