  • Turbulence-quelling fluid-flow controller and method
    Patent number: 5158235
    Abstract: A turbulence-quelling fluid-flow controller and method having a housing with a fluid flow passageway and a vane member disposed in the passageway. Inclined surfaces extend on the member between the vanes, and the inclined surfaces and the vanes have the fluid flowing thereagainst and direct the flow to a nozzle, all for quelling turbulence in the flow. The method diverts the flow from the first path and into a second path, at a right angle to the first path, and between vanes, all for quelling.

  • Apparatus and method for feeding sheets to a sheet gatherer
    Patent number: 4819929
    Abstract: Apparatus and method of feeding sheets to a sheet gatherer, comprising moving the sheets along a horizontal path and then arcuately downwardly to lay the sheets in the gatherer hopper. The sides of the sheets are supported by members which have irregular surfaces disposed in vertical upstanding planes for engaging the opposite sides edges of the upstanding sheets and thereby support the sheets while advancing them toward the hopper. The sheets are continuously moved from a loading position and in the horizontal direction and then through a downwardly extending arc and into the hopper.

  • Support for edge-standing sheets
    Patent number: 4747593
    Abstract: An upstanding sheet support system which utilizes either brushes or a jagged configuration member for engaging the opposite sides of sheets standing in a horizontal bundle where the sheets are standing on their edges on a floor. The side support members can either be stationary or moving, for supporting the sheets, and there is no requirement for any other support of the sheets, such as the requirement of the usual backstop, special handling, or binding of the bundle, since the sheets are self-standing by virtue of the spaced-apart engaging the opposite sides of the sheets in the bundle.
