    Filed: October 15, 1993
    Date of Patent: September 26, 1995
    Assignee: University Patents, Inc.
    Inventors: Marvin H. Caruthers, William S. Marshall, Wolfgang Brill, John Nielsen
  • Patent number: 5260113
    Abstract: A minimum visibility seam tape and method of joining at least two substrates with the tape. The substrates joined typically are sign faces or awnings comprising a composite of thermoplastics and a woven scrim. The seam tape is a woven or nonwoven scrim embedded in or coated with a thermoplastic polymer.
    Type: Grant

    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: James A. Pontuti, Robert W. Warner, Richard F. Theissen, John A. Nielsen
  • Patent number: 5232720
    Abstract: In a method for the preparation of cheese for distribution, milk is concentrated to a dry matter content corresponding to a desired dry matter content of finished cheese through the separation of whey. The concentrated milk is mixed with additives including a substance capable of forming carbon dioxide upon mixing with lactic acid bacteria occurring naturally in milk. When the concentrated milk/additive mixture is packaged into distribution-ready packagings in which it coagulates to form cheese, the carbon dioxide forms tubular passages in the cheese.

    Assignee: Tetra Alfa Holdings S.A.
    Inventor: John Nielsen
  • Patent number: 5218103
    Abstract: The present invention relates to new and useful nucleside thiophosphoramidite, polynucleotide dithioate phosphoramidite and polynucleotide phosphorothioamidate phosphoramidite compounds as well as the process whereby these compounds can be used for synthesizing new monoucleotides and polynucleotides having phosphorodithioate, phosphorothioamidate, phosphorothiotriesters and phosphorothioate internucleotide linkages.
    Type: Grant

  • Patent number: 4903590
    Abstract: Brine, pickle or another liquid is injected into a piece of food through groups of hollow needles, which are plunged into various parts of said piece of food. Different amounts of liquid are injected through said groups of needles in dependency of estimated liquid absorbing characteristics of the respective parts of the piece of food, so as to obtain a substantially uniform distribution of the brine or liquid therein. Pressurized liquid may be supplied to each group of needles from a common source through a liquid valve, and the amount of liquid injected into the various parts of the piece of food may then be controlled by controlling the pressure of the liquid supplied to said group of needles by adjusting the valve. Such adjustment may be controlled by an electronic control device comprising a micro processor.

  • Patent number: 4079919
    Abstract: A water spray quench process and apparatus for the hardening of steel agricultural discs and like articles with minimum warpage and maximum exposure to the quenching water. A steel article heated in a furnace to a temperature above its austenitizing temperature is moved horizontally into a quenching station, supported on several support pins below the article with a positioning member above the article, and sprayed with water from a series of nozzles both above and below the article to rapidly and effectively quench the article to a minimum temperature. Once the article has been cooled by the quenching water, it is expelled from the quench station.
