  • Notch diaphragm pressure sensor
    Patent number: 6367333
    Abstract: A pressure sensor includes a tube for channeling a fluid therethrough. A notched seat is disposed in an outer surface of the tube and is open at circumferentially opposite ends, with a flexible diaphragm at the bottom thereof. The diaphragm is planar, and blends at its perimeter coextensively with an arcuate inner surface of the tube. A gauge is mounted in the seat above the diaphragm for measuring flexure thereof under pressure of the fluid inside the tube.
    Type: Grant
    Filed: November 30, 2000
    Date of Patent: April 9, 2002
    Assignee: APEX Medical, Inc.

  • Method for producing large crystals of complex molecules
    Patent number: 6221153
    Abstract: Compressed gases, liquefied gases, or supercritical fluids are utilized as anti-solvents in a crystal growing process for complex molecules. Crystals of the present invention exhibit greater crystal size and improved morphology over crystals obtained by conventional methods.

  • Viral inactivation method using near critical, supercritical or critical fluids
    Patent number: 5877005
    Abstract: The invention involves the use of supercritical or near-critical fluids for the inactivation of viruses, especially enveloped or lipid protected viruses, and nonenveloped, protein encased viruses, viral-like particles and other pathogens in any matrix, but preferably in solutions containing biologically active proteinaceous products of natural or genetic engineering origin or in semi-solid or solid support matrices which are thermally labile or sensitive to conventional viral inactivation techniques. Novel apparatus also are provided.
