Patent number: 4019938Abstract: Insulation board comprising a urethane foam core sandwiched between a thin flexible membrane and a thicker inflexible panel is made by dispensing foam forming materials onto a moving continuous sheet of the thin flexible membrane and depositing individual panel segments onto the foam as it expands.

Patent number: 4012272Abstract: A method and apparatus for continuously forming a reinforced flexible hose is disclosed. The apparatus includes a hose-forming device including a plurality of synchronously-rotatable mandrels with a plurality of spaced apart, annular grooves therein fixedly disposed in skewed fashion relative to each other. The reinforcing element of the flexible plastic hose is formed from metal wire which is delivered tangentially into the grooves in the rotating mandrels in a sequential, progressive fashion thereby forming a helically arranged wire structure. Simultaneously with the delivery of the wire to the mandrel grooves, the longitudinal edge of the plastic ribbon which is to form the body of the hose is pre-moistened with an appropriate rapid-drying, liquid-bonding agent and then circumferentially wrapped about the wire to completely enclose it. The succeeding edge of the following tape wrap is adhesively bonded to the subsequent tape wrap.Type: GrantFiled: August 22, 1975Date of Patent: March 15, 1977Inventor: Larkin Hall Tiner

Patent number: 4010051Abstract: A method of bedding a load-carrying member on a supporting foundation in which one or more open-ended axially compressible moulds are placed on the foundation and a bonding agent which includes a thermosetting resin capable of bonding to both the underside of the member and to the foundation is placed in the mould or moulds. The member is then placed on the mould or moulds and, by its own weight, or by a superimposed load, compresses the mould or moulds axially until the member is itself pressed into contact with the bonding agent, which is contained laterally by the mould or moulds, the bonding agent then being allowed or caused to harden. The method is particularly useful for bedding manhole covers on a manhole wall.Type: GrantFiled: September 4, 1975Date of Patent: March 1, 1977Assignee: Corrosion Technical Services LimitedInventors: Michael H.
