    摘要： A two-compartment pierceable cartridge adapted for reinforcing or strengthening a stone or coal wall by insertion into a hole that had been bored into the wall, one compartment of which contains a polyisocyanate of diphenylmethane, and the other compartment of which contains a mixture of a polyetherglycol having a hydroxyl number between 200 and 400, between 10 and 20 percent by weight of a plasticizer, and between 0.3 and 5.0 percent by weight of water. When the cartridge is broken up and its contents are mixed, a foamed polyurethane resin is formed in situ which plugs the bored hole and thereby reinforces the wall.

    摘要： The present invention relates generally to improvements in fasteners of the snap-in type for securing a plurality of workpieces or panels in fixed position relative to each other and more particularly to novel and very practical one-piece plastic snap-in type fasteners. Fasteners of the type contemplated by the present invention and disclosed herein include a head section, and an elongate shank section integral with and extending therefrom. The shank section is of novel design and is centrally apertured longitudinally for accommodating a fastener screw element. The disclosed fastener is substantially Z-shaped in cross-section in the vicinity of a shoulder adapted to engage the side of a workpiece oppositely disposed from the side engaged by the head of the fastener. A unique structural arrangement of the elongate shank section assures the subjection of a diagonal web portion thereof to stress upon initial insertion of the shank section within a work aperture, and a screw element is insertable within a longitudinal aperture centrally disposed within said diagonal web.

    摘要： A series of multi-compartmented packages is produced continuously by forming a web of film, e.g., biaxially oriented, heat-set polyethylene terephthalate, into a continuously advancing convoluted tube having a partially single-ply and partially double-ply wall, sealing the inner to the outer ply so as to form at least two linear junctures, one adjacent the inner edge and one adjacent the outer edge of the web, thereby forming at least two adjacent compartments with the inner ply common to two compartments, feeding different fluent materials to the different compartments, constricting the loaded tube at spaced intervals and applying a pair of encircling closure means to the constricted areas, and severing the tube between the pair of closure means.

    摘要： The present invention relates generally to improvements in screw type fasteners and to novel methods of applying such fasteners to a preformed aperture in a workpiece. The embodiments of the present invention disclosed in the accompanying drawing includes a headed screw member, the entering extremity of which is encapsulated by an adhesive having the functional characteristics of a partially cured epoxy resin. Interposed between the threaded peripheral surface of the screw shank and the aforesaid adhesive is a release coating to prevent the establishment of a bond between the adhesive and the peripheral screw surface when said adhesive is completely cured or solidified within a work aperture.
