    Abstract: Three dimensional molded objects are produced from a plurality of expandible elements deposited in a mold by heating and moving the expandible elements during heating in the mold. The expandible elements have at least one layer of vertically lapped material held in a pre-compressed state during or before they are deposited in the mold. Movement is achieved by physically moving the mold continuously or periodically during heating, by blowing air or other gas into the mold continuously or periodically during heating, or by heating and depositing and moving the expandible objects at the same time.

    Abstract: An improved steam heated corrugating roller includes an inner heating steam chamber constructed with a longitudinal cone shape with the exit for condensates at the wider end. Conduits are connected through the wider ends to a ring shaped housing. A ring is placed in the housing and includes several independent sectors which allow for radial movement between two positions vis a vis the bottom of the housing. This allows the conduits to remain open when the roller is spinning and closed when it is not spinning.

    Abstract: This relates to a mold for rebonding polyurethane and like plastic foam to form selected shapes. A typical shape may be a back or a seat member for an article of furniture. The mold is improved in that the bottom mold member, which is particularly designed in accordance with the desired configuration of the shape, has been formed of epoxy which is readily moldable at a low cost. The mold is also improved by providing the base plate of the mold with a ramped floor which facilitates the drainage of condensate from a lower steam chamber. The configuration of the ramped floor allows for quick removal of the condensate and serves to reduce the volume in the steam chamber thereby minimizing pressure build-up in the steam chamber. This results in lower steam pressures being used during the curing process and for a shorter curing operation. The lower steam pressure also avoids leakage of steam and water from the epoxy mold.

    Abstract: An apparatus and method are provided wherein a cavity defined by a rotating hollow member, such as a draw roll in a fiber processing system, is supplied with a hot fluid so as to heat the exterior surface of the hollow member. The fluid is withdrawn from the cavity and passed through a rotating syphon conduit which is fixedly connected to the hollow member. The temperature of fluid flowing within the syphon conduit is detected by a suitable temperature detector positioned within the syphon conduit so as to indicate a drop in fluid temperature when normal fluid flow to the hollow member cavity is interrupted.

    Abstract: An apparatus for injection molding an article includes a pair of mold members, at least one of which is movable toward and away from the other. Each mold member includes a base plate, a manifold plate and a cover plate. Each base plate has inner and outer surfaces with a mold cavity in its inner surface and an annular recess in its outer surface. A plurality of connected grooves is in the bottom of the recess to form a channel. The manifold plate is an annular plate which is seated in the recess in its respective base plate. The manifold plate has inlet and outlet passages which extend to separate ones of the grooves in the base plate. The cover plate extends across the outer surface of the base plate and the manifold plate to hold the manifold plate in the recess. One of the base plates has a hole therethrough from its outer surface to its mold cavity to allow the flow of molding material into the mold cavity.
