  • Aspirated syphon shoe
    Patent number: 5109612
    Abstract: A low differential pressure rotary syphon for the purpose of removing condensate from the interior of steam a heated dryer drum under low differential pressure conditions. The reduction in the magnitude of differential pressure required to remove the condensate is accomplished through the direct introduction of steam into a central plenum area receiving condensate thereby reducing the mass density of the condensate mixture. The reduction in mass density and the steam introduced acting directly on the condensate within the central plenum area facilitates the removal of the condensate from the drying drum interior.

  • Anti-corrosive rotary joint
    Patent number: 5110162
    Abstract: This invention pertains to a rotary joint for use with rotating machinery where the joint is conveying high temperature corrosive fluids such as molten salts. The joint includes both a stationary head to which external connections are made and a housing mounted on and rotating with a rotary apparatus with which the joint communicates. Alignment of the components is maintained through the interaction of two sleeve bearings disposed between a nipple coaxially extending from the head and the joint housing surrounding the nipple; the sleeve bearings being axially displaced from each other, the primary seal occupying an intermediate position. The primary seal is a spherical seal, interposed between a stationary nipple seal surface and a rotary housing sealing surface. The seal is preloaded by means of an external joint biasing support bracket to reduce leakage under conditions of low internal fluid pressures.

  • Method of forming reinforced thermoplastic members
    Patent number: 5096645
    Abstract: Extruded thermoplastic members, particularly structural members, are reinforced by longitudinally extending pre-stressed elements, such as filaments or matting. The elements, while under tension, are drawn into an extrusion crosshead die forming the thermoplasatic member. The elements are fully imbedded within the thermoplastic material while under tension and curing of the thermoplastic material, and final curing of the tensioned reinforcing elements, if a thermosetting resin impregnated element is used, occurs while the elements are under tension, the material of the member and the elements intimately bond and the tension forces within the elements reinforce the member at the desired locations. The forming of the reinforced member is a continuous operation.

  • Air controlled rotary joint compensator
    Patent number: 5067824
    Abstract: The invention pertains to the method and apparatus of compensating for the axial bearing load forces imposed upon rotary joints conveying a pressurized fluid medium, such as steam, by imposing an axial force on the rotary joint housing proportional to the pressure within the rotary joint by use of a distinctively different pressurized medium than that comveyed by the joint, such as compressed air. An expansible chamber motor capable of imposing an axial force on the rotary joint utilizes compressed air whose pressure is controlled by a sensing and regulating system responsive to the pressure within the rotary joint.
