Foam thermoplastic injection molding apparatus and method produces structurally superior foam injection molded products. The process includes plasticating solid polymer to a polymer melt; accumulating the melt in an accumulator having a telescoping inlet, which allows the first melt which enters to be the first to leave the accumulator; combining a preselected amount of melt with a preselected amount of gas in bubble form to form homogenized polymer foam; shearing the homogenized polymer foam to reduce the size of gas bubbles; and injecting the polymer foam through a special gate assembly into a mold. The gate assembly has a removable nose which remains with the mold, allowing the foam to expand within the mold but not allowing the foam to escape the mold. The process and apparatus allow low molded-in stress products to be produced, and can process recyclable thermoplastics, either single materials or mixtures. Thus, no segregation of materials is required.

A composite structural material suitable, for example, as a replacement for wooden boards, is disclosed. It comprises a dimensionally stable core material ensheathed in a dimensionally stable, laminar covering that is adherent to the core material. The laminar covering is comprised of at least one layer of parallel cords () bonded to at least one layer of a rigidified web material () selected from the group consisting of paper and cloth. Suitable core materials include polyurethane foam (), optionally filled with particles () of granulated rubber, expanded perlite, expandable polymer beads, and/or glass microspheres. The parallel cords () preferably are supplied in the form of a strip of polyester cloth, as the warp cords thereof. The web material () preferably is kraft paper that is rigidified with an epoxy resin.

A pipe severing device (1) and method utilizing a chain (13) having stress inducing wheels (19) efficiently and safely severs brittle materials including cast iron, vitreous clay, cement and asbestos pipe. The device includes an actuating handle (6) which pivots over a pipe support surface (3). Upon pivoting over the surface, holddown arms (7) attached to the actuating handle frictionally grasp a pipe. The handle may then pivot about a second point or remain rigid, in either case engaging a first limit switch (25) which actuates a hydraulic cylinder (35). The hydraulic cylinder tightens the chain causing the stress inducing wheels to create stress concentration points around the circumference of the pipe. Cracks propagate between stress concentration points, quickly severing the pipe. The pipe support surface includes resilient pads (5a,b) which further frictionally grasp the pipe.
