Abstract: For a workpiece having a metal part bonded to a rubber part, a method is devised to separate the metal and rubber parts. A flame is used to heat a portion of an exposed surface of the metal part, while moving the flame relative to the metal part until substantially all the exposed metal surface is heated. The process is repeated until the metal and rubber parts separate.

Abstract: A method of producing dry processed fiberboards from resin-bonded waste composite wood products, wherein said wood products are chemically treated in a pre-heater unit of a refiner system under super-atmospheric pressure in the presence of steam to disrupt adhesive polymer bonds, formed into fibers in a subsequent disc refiner unit of the refiner system and further processed by a dry process to form fiberboards.

Abstract: Self-healing copolymeric materials comprising a plurality of intermediate strength crosslinks are provided. The copolymeric materials comprise a silicon component and a plurality of crosslinking components. The crosslinking components comprise a polymeric structure forming a structure held together by ionic and/or hydrogen bonding with a net intermediate strength. The plurality of intermediate strength crosslinks provide toughness to the material, and allow for rehealing by allowing reforming of the crosslinks after a disruptive stress incidence. The material is also suited for recasting, and can be used as an active matrix by incorporating additional substances. Articles of manufacture incorporating such materials, and methods of recasting such materials are also provided.

Abstract: A method of repairing or refurbishing a filter screen is described. The type of screen is defined in the specification. The repair or refurbishment is effected by stripping worn or damaged wirecloth from the surface of the frame and placing fresh cloth over the frame and tensioning it as appropriate. Heat is then applied so as to soften surfaces of the frame over which wirecloth is stretched, so that the latter can penetrate softened plastics material in the surfaces and become embedded therein. The frame and its associated fresh cloth is allowed to cool, after which the applied tensioning is removed. Exposed edges of the wirecloth can be trimmed back to the surrounding flange. Plastics material may be applied to the surface of the frame which is to receive the new wirecloth, before the latter is fitted, to provide additional plastics material for bonding the wirecloth to the frame.

Abstract: A method for consolidating blocks of natural stone or recomposed material includes placing the block on a platform over a liquid and gas impermeable base sheet with spacers. Liquid and gas impermeable lateral sheets with spacers are glued to the side walls and extend beyond the top of the block. The block is inserted into an autoclave and a vacuum is applied. A fluid resin is dripped on the top of the block to cover it and to flow into the interstices between the block and the sheets. The vacuum is removed from the autoclave so that the resin penetrates into fractures and cavities in the block and the resin is allowed or induced to harden.

Abstract: A method for securing a shell assembly to a pipeline. A two part shell assembly is secured to the pipeline and holds in position an annular sealing arrangement located about a predetermined area of the outer surface of the pipeline. The sealing arrangement includes a containment ring surrounding an annular seal. The containment ring is provided with connected through passages so that sealant can be introduced by a hole in the assembly into the passages to provide sealing between the containment ring and the pipeline, and between the containment ring and the shell assembly. Thus, should the annular seal fail during service the introduced sealant provides a seal.

Abstract: An improved repair bridge for windshield repair which is easier to drag along in proper position, a repair bridge which inherently applies a balanced force on opposite sides of the chip/crack, a bridge which requires substantially less adjustment bolt force, and which is provided with an adjustment bolt force gauge so that even a novice will be able to apply optimum crack spreading force without enlarging the crack. The generally U shaped bridge comprises: a left arm portion, a right arm portion, and a middle portion extending between and connecting the arm portions. Two upright finger bolts are each matingly threaded through an unconnected end portion of one of the arms; and, two plastic suction cups are each carried by a central portion of one of the arms. An upright resin injection head is adjustably screwed through the middle portion.

Abstract: An initial resin substrate is formed by laminating resin layers, and one surface of the initial substrate is heated and pressed by a molding die to mold a projected and dented surface such that substantially no deformation occurs on the resin layer providing a surface opposed to the one surface of the initial substrate. A reversible image display medium is produced by a method comprising the steps of accommodating a dry developer into the concavities and fixing a second substrate to the first substrate using an adhesive. Alternatively a reversible image display medium may be produced by, e.g.

Abstract: There is disclosed a method and composition for cosmetically repairing a surface void in polyolefin objects. The method involves inserting a repair composition into the void and then applying heat thereto to fuse the repair composition with a surrounding portion of the polyolefin object. The repair composition is a physical mixture of a thermoplastic powder, a resin binder, and a solvent, having a paste-like consistency. The repair composition may be neutral in color, or may contain a colorant to closely match the underlying object. The heating step can be performed with an open flame or with a heat gun.
