  • Patent number: 5334300
    Abstract: There is disclosed a two-chambered electrocell comprising one or a plurality of anode chambers, a crude flow inlet and a crude flow outlet communicating with the anode chamber, one or a plurality of cathode chambers, and a catholyte outlet communicating with the cathode chamber, wherein cylindrical anodes are located in the anode chamber, wherein the anode chamber is defined by a membrane having a first side and a second side, wherein the first side of the membrane communicates with crude fluid circulating within the anode chamber, and wherein the second side of the membrane is supported by a plurality of support members, wherein a pressure of crude fluid in the anode chamber deflects the membrane between the support members toward the cathode to form a crude flow path having a constantly changing direction, and wherein the cathode chamber is defined by the second side of the membrane and the two-chambered electrocell, and the support members and a cathode are located in the cathode chamber.

  • Patent number: 5287625
    Abstract: An improved sandpaper cutting guide is disclosed having a series of recesses to receive different sized pieces of sandpaper. The longer side of a standard sized sheet of sandpaper is placed in one of the slots for cutting the sheet in half or the end of the standard sized sheet may be placed in another slot for cutting a one-third sheet piece. A cutting tool is inserted through a slit in the guide and drawn across the guide to cut a selected one of several smaller, also standard, piece sizes from the sheet. The same slit guides the cutting tool for all sizes with size being determined by the recess into which the sheet is placed. Access openings are provided to aid in removal of the cut piece from the guide. Preferably, recesses are provided for cutting the standard sized sheet into halves, thirds, quarters or sixths.

  • Patent number: 5281430
    Abstract: There is disclosed an osmotic concentration cell wherein the flow chamber of the osmotic concentration cell has a continually changing flow path to provide a region of high turbulence to a semipermeable membrane defining the flow chamber. High turbulence at a first semipermeable membrane interface significantly reduces membrane fouling during osmotic concentration and allows for concentration of products with high suspended solids content. The inventive osmotic concentration cell can be used for a variety of purposes including, for example, producing low alcohol wine, concentrating a thin wine into a premium wine, concentrating a low quality grape juice into a higher quality grape juice for fermenting a more premium wine, concentrating various fruit or vegetable juices, and concentrating various beverages, such as teas or coffee.

  • Patent number: 4602808
    Abstract: A flexible corrosion-resistant tubular sleeve provides protection for hose assemblies subjected to abrasion, kinking, or accidental rupture due to flexure. The sleeve also provides routing control for hose end assemblies, providing greater axial strength, yet greater flexibility by the incorporation of a helical body portion. In a preferred embodiment, the sleeve is a single-piece body of molded polypropylene, and defines a pair of annular end portions integrally joined together by the helical body portion.

  • Patent number: 4316647
    Abstract: An audio connector comprising the combination of a pair of detachable members, one of such members including a hollow sleeve-like conductive housing and a plurality of male conductive contact pins, the other one of such members having a post-like conductive housing and a plurality of female conductive pin receptacles adapted to mate with the male contact pins. A mechanical latching system including a unitary resilient latch having an elongated tongue-like conductive portion and a pair of conductive wing-like members offset from the elongated conductive portion is mounted on one of the pair of conductive housings. A manually actuated release means is mounted on the latch. The elongated tongue-like portion of the latch is adapted to slide within a polarization groove formed within the other one of the pair of conductive housings, such groove being cut through a lip formed on the inner periphery of the hollow sleeve-like conductive housing.
