  • Patent number: 4600589
    Abstract: Meat is tenderized by adding thereto a proteolytic enzyme obtained by culing the microorganism, Trichoderma reesei strain MCG 80. The enzyme is an aspartic acid protease with proteolytic properties similar to the animal protease, Cathepsin D. The enzyme acts selectively upon the myofibrillar proteins of meat producing a desirable uniform texture. Culturing of the microorganism in a medium containing glucose and lactose results in high enzyme yield.
    Type: Grant

    Date of Patent: July 15, 1986
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Frederick M. Robbins, Alfred L. Allen, John E. Walker, Samuel H. Cohen
  • Patent number: 4490427
    Abstract: This application discloses adhesive webs and their production. The thermally adhesive webs of this application are comprised of substantially parallel fusible polymeric filaments thermally bonded to and interconnected by randomly arranged polymeric fibers. The web may be comprised of co-, ter-, or higher polyesters or polyamides, such as a terpolymer or nylon 6, 66 and 12. The parallel filaments may comprise about 20 to 80% by weight of the web and the interconnecting fibers 80 to 20% of the web, with the weight of the web being about 10 g/m.sup.2 to below about 80 g/m.sup.2. The web may be in the form of a tape.

  • Patent number: 4037048
    Abstract: A process for interpreting remotely sensed data to determine the nature and presence of several conditions. Data sensed at two different wave bands are mathematically divided to determine the ratio of the energies coming from the observed object at the two wave bands. Unlike density addition or subtraction which furnish only the difference in the densities on the film, the step of mathematical division produces a change in pattern as well as density. The changes in the pattern can be interpreted to provide additional information from the data.
