Patents by Inventor Robert C. Menson

Robert C. Menson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Novel particulate compositions
    Patent number: 4323478
    Abstract: An improved method and apparatus is disclosed for producing frozen particulate compositions from liquid feedstock. A continuous stream of liquid feedstock is passed through an orifice and into a liquid freezant without the orifice contacting the freezant. Compositions produced by this improved method have low proportions of fine and large particles, yielding particularly beneficial results in the case of quality control materials. The compositions are advantageously employed in automated weighing and filling apparatus.
    Type: Grant
    Filed: December 19, 1979
    Date of Patent: April 6, 1982
    Assignee: Baxter Travenol Laboratories, Inc.
    Inventors: Thomas H. Adams, James P. Beck, Robert C. Menson
  • Amylase assay
    Patent number: 4233403
    Abstract: Disclosed herein are a method and a reagent test kit, both using an improved substrate to measure the amylase content of a sample. The substrate used is a glycoside consisting of a defined polysaccharide glycosyl residue and a substituted aromatic radical attached to the terminal unit of the glycoside. When detached from the polysaccharide, the aglycone exhibits a different spectral absorbance than the substrate.
