  • Patent number: 5915760
    Abstract: A movable mold is movable toward and away from a fixed mold so as to close and open the mold. The fixed mold includes an intermediate plate facing a movable-side mold plate. This intermediate plate has a retainer-molding recess which cooperates with the movable-side mold plate to form a retainer-molding cavity, and a core pin, which cooperates with a housing-molding recess to form a housing-molding cavity, is mounted on the intermediate plate. A retainer, molded in the molding cavity, is moved downward by an ejector pin into a position where the retainer is disposed coaxial with a housing. Then, the two molds are again closed together, so that the housing and the retainer are connected together, and then this assembled product is taken out.

  • Patent number: 4698887
    Abstract: Prefabricated insulated pipeline section having a one-piece cast cured and dried insulative liner formed of lightweight aggregate in a foamed portland cement paste binder bonded to the inner surface of a tubular outer casing. The liner composition may be cast in place between the liner and the pipe, and wet cured at elevated temperature. Bonding between the pipe and the liner composition is avoided by employing a cement cure retarder on the outer surface of the pipe or by mechanically debonding the pipe from the liner during curing. After curing, the pipe is withdrawn to expose the inner surface of the liner to permit rapid drying at elevated temperature. The prefabricated insulated sections permit simplified pipeline construction at reduced cost as compared with traditional methods of applying half shells of insulation to the pipeline on site.
