Patent number: 5287625Abstract: 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.Type: GrantFiled: March 8, 1993Date of Patent: February 22, 1994Inventor: John R. Herron

Patent number: 5281430Abstract: 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.Type: GrantFiled: December 8, 1992Date of Patent: January 25, 1994Assignee: Osmotek, Inc.Inventors: John R. Herron, Edward G. Beaudry, Carl E. Jochums, Luis E. Medina

Patent number: 4602808Abstract: 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.Type: GrantFiled: June 26, 1984Date of Patent: July 29, 1986Assignee: Dana CorporationInventors: John R. Herron, Alan M. Spisak
