Ramesh C. Trivedi 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).

  • Alpha-amylase assay and substrates for use therein
    Patent number: 4505756
    Abstract: A maltodextrin phosphorylase limit dextrin in the presence of maltodextrin phosphorylase and inorganic phosphate, is used as a substrate for alpha-amylase, which initiates a series of enzymatic reactions resulting in a chromogen response which can be used to measure the concentration of alpha-amylase in a body fluid. A novel limit dextrin and its preparation also are described.
    Type: Grant
    Filed: September 1, 1981
    Date of Patent: March 19, 1985
    Assignee: CooperBiomedical, Inc.
    Inventors: Paul T. Nix, Rebecca D. Goldfarb, Linda J. Stong, Lorraine E. Sulick, Ramesh C. Trivedi, Stanley W. Morgenstern

  • Chemical analysis method using reaction container
    Patent number: 4040786
    Abstract: For use in measuring the extent or rate of optical density change produced by a reaction a rigid or semi-rigid disposable reaction container is disclosed of the type comprising a windowed reaction chamber adapted for the transmission of light therethrough and an auxiliary chamber that is separated from the reaction chamber except for an opening which is small enough to prevent substantial diffusion or movement of liquid from one chamber to the other when under static conditions but through which a solution of a reagent in the auxiliary chamber may be forced so as to enter the reaction chamber and commingle with a solution of another reagent and thereby trigger a reaction, improvements comprising the provision in a receptacle having side walls, end walls and a bottom wall of a projection which extends a substantial distance upwardly from the bottom wall so as to separate the lower part of the receptacle into two portions adapted to separate liquid in one of said portions from the other portion in combination w
