  • Patent number: 5794670
    Abstract: A collapsible container liner for use within a bulk container having a substantially rigid top, bottom and side walls and a filler opening in the top wall. The liner is a collapsible bag of a flexible material with top, bottom and sides which correspond to the container walls within the interior of the container. A first opening in the liner top corresponds to the filler opening in the container top wall. A seal is formed between the container top wall and the liner top around the periphery of the filler opening and the first opening. A second opening in the liner top is spaced from the first opening and has an evacuation outlet attached to the liner top around the periphery of the second opening. Air is evacuated through the outlet from the space between the liner and the interior of the container, a vacuum forms which collapses the liner against the container interior surfaces.

  • Patent number: 5642318
    Abstract: The present invention provides a system for testing a memory array and corresponding support circuitry. The present invention provides a highly efficient testing mode to be entered that allows any type of advanced testing to be performed on the memory array without regard to the restrictions imposed by the various status flags that may be present. The testing mode can be entered by a completely user-defined mechanism. During this testing mode, the user has complete control over the contents of the memory array and can also have complete control over the positioning of the write word line with respect to the read word line without, for example, any write-read word line pointer equality signals being generated. In one example of the present invention used in a FIFO, testing times required for data retention testing are reduced from approximately six seconds to approximately

  • Patent number: 5485041
    Abstract: An acceleration sensor that includes a permanent magnet mounted for movement within a cylindrical cavity in a body of non-magnetic material. The magnet has a cylindrical geometry and an outer surface with a first portion of electrically conductive construction entirely around the magnet adjacent to one axial end thereof, and a second portion of electrically non-conductive construction entirely around the magnet adjacent to an opposing end thereof. A pair of diametrically opposed electrical contact leaves extend through openings into resilient sliding contact with the magnet. The magnet is resiliently urged toward one end of the cavity such that the contacts are in engagement with one of the first and second surface portions.

  • Patent number: 5401006
    Abstract: A method and press for uniformly quenching a heated annular workpiece while fixturing the workpiece to prevent distortion during quenching. The press has a conically shaped lower die for receiving a workpiece to be quenched thereon and a vertically reciprocable conically shaped upper die for clamping and fixturing a workpiece between them. The press has a generally cylindrical quench ring carried by the upper die for engaging against the lower die to form a chamber around the workpiece to immerse the workpiece in quenching fluid. The lower die has a plurality of spaced apart inlets for uniformly distributing quenching fluid around the workpiece and which are preferably angled relative to the center axis of the lower die for producing a swirling turbulent flow of fluid within the chamber to more rapidly and uniformly quench the workpiece.

  • Patent number: 5286042
    Abstract: A tool holder for a machine tool is provided with a tool shank clamping mechanism in the form of an expanding or contracting sleeve, hydraulically actuated, and the chuck has an annular groove aft of an annular collar on the clamping mechanism. Circumferentially spaced conical screws, mounted axially in the collar, bear against the body of the tool chuck and allow fractional tilting of the clamping mechanism relative to the true holder and spindle axis to provide exact centering of the cutting end of the mounted tool.

  • Patent number: 5049844
    Abstract: A relay comprising an electromagnetic coil wound on an insulating bobbin, the central cavity of which encloses a central spring-biased contact actuated by a magnetic armature in response to energization of the coil, to make or break contact with one or more fixed contacts also enclosed. A U-shaped member and a heel plate, both of highly magnetically permeable material, surround the coil and complete the magnetic circuit for flux generated by the coil. The magnetic armature is constructed and arranged such that it is accessible from the exterior of the enclosed relay to adjust the position of the spring-biased contact of the relay after it is assembled to conform with the desired level of voltage required to actuate the relay.

  • Patent number: 4926829
    Abstract: A fuel delivery system for internal combustion engines in which an electric-motor fuel pump supplies fuel under pressure from a tank to a fuel injector carried by the engine, and excess fuel is returned by a pressure regulator from the engine to the supply tank. A restriction is positioned in the fuel return line to restrict flow of return fuel therethrough, and thereby create a back-pressure of fuel in the return line. A pressure sensor is coupled to the return line between the pressure regulator and the restriction and drives the fuel pump as an inverse function of fuel pressure in the return line, and thus as a direct function of fuel demand at the engine.

  • Patent number: 4796547
    Abstract: A device for dispersing fine particles in the agglomerated state comprises a body, a fine particle channel provided in the body and terminating in a spout in the form of a slit, and a clearance provided in the body, inclined downstream with respect to the fine particle channel and communicating with the fine particle channel for emitting a gas into the fine particle channel. Since the spout is in the form of a slit, a large amount can be simultaneously dispersed without losing the dispersing performance of the single hole type dispersing device. When a plurality of such dispersing devices are attached to the combustion gas passage forming wall of a furnace and arranged so that the more upstream they are disposed, the greater is the throw of the reactant-containing gas emitted therefrom, the reactant is diffused in the combustion gas and uniformly distributed.

  • Patent number: 4459771
    Abstract: A steam iron set including a water pump mountable on a steam iron in exchange for a detachable reservoir for containing steam generating water. The water pump forces out water toward the soleplate of the iron to pass the water through a steam generating chamber and a steam channel formed in the soleplate and discharge the water from steam vents formed in the ironing surface. Fur particles or like evaporation deposit, lint, etc. can be removed from the interior of the soleplate by the flow of water to eliminate the likelihood that the flow of the steam will be impeded during ironing.
