  • Patent number: 4191500
    Abstract: A method for the dense-phase flow of particulate solids utilizes a pressurized feeder and flow splitter which transports and equally divides particulate material at essentially the bulk density with only the gas contained in interstices of the solid particles being used to transport the particles. The feeder comprises a vessel which is pressurized, a gas source for pressurization and an outlet line with a full opening valve located immediately adjacent to the feeder. The loaded vessel containing particulate matter is pressurized, followed by opening the valve adjacent the feeder, the valve and relatively empty downstream line when flow is initiated being the key to successful operation of the dense-phase feeder. The downstream flow divider evenly distributes the dense-phase material to, for example, a multiplicity of feed passages in a multi-passage injector.

  • Patent number: 4188122
    Abstract: A laser beam is split into two components which remain coherent, are differently frequency-shifted, orthogonally polarized and recombined. The recombined beam is expanded and directed into polarization type beam splitter directing one component into a reference branch, the other one into a test branch. Both branches return the component beams which are combined and polarization filtered so that they may interfere on account of local optical path differences. Brightness oscillations are photoelectrically detected in individual points of a plane intercepting the interference beam and referenced as to phase against a reference oscillation derived from a particular point in that plane. The phase differences are electronically acquired point-by-point for generation of a contour map or its equivalent of the optical path differences as between a test object in the test branch and a reference object in the reference branch.

  • Patent number: 4181000
    Abstract: A method and apparatus are provided for automatically controlling the strain rate during superplastic forming of a blank of material into a part. The method and apparatus produce a part in a minimum time by deforming the material in its optimum superplastic conditions. A relationship is determined between time and the pressure required to form the blank against the configured surface of a die at a strain rate which causes the blank to flow superplastically. The blank is positioned in the die and held at a temperature at which the material exhibits superplasticity. Pressure is automatically applied across the thickness of the blank in accordance with the previously determined relationship between time and pressure until the part is formed. The apparatus comprises conduits connected to a die and to a high pressure gas. Valves in the conduits regulate the pressure applied to the blank. A controller receives command signals from a programmer which is programmed with the desired time vs pressure relationship.
