  • Compositions for microencapsulation of antigens for use as vaccines
    Patent number: 6913767
    Abstract: Methods and compositions are provided for the encapsulation of antigens in PLGA microspheres for use as vaccines. Such microspheres can also contain adjuvants. Mixtures of microspheres are provided which release antigen at desired intervals to provide boosts with antigen.
    Type: Grant
    Filed: April 30, 1997
    Date of Patent: July 5, 2005
    Assignee: Genentech, Inc.
    Inventors: Jeffrey L. Cleland, Amy Lim, Michael Frank Powell
  • Method for drying microspheres
    Patent number: 6080429
    Abstract: A method for drying microspheres in a fluidized bed is provided, along with a composition comprising microspheres dried by that method.
    Type: Grant

  • Nonvolatile magnetic analog memory
    Patent number: 5504699
    Abstract: A nonvolatile analog magnetic memory includes a substrate comprised of saturable and desaturable magnetic domains at distinguishable fixed locations, a bi-directional drive circuit to selectively write data to the magnetic domains by first saturating a selected magnetic domain with current flowing in one direction, followed by desaturating the magnetic domain with current flowing in the reverse direction of the saturating current, lowering the magnetic flux density to a level corresponding to the magnitude of an analog input electrical signal within a range of magnetic flux density levels between a zero point and a full scale point, sensors and a sensor select circuit to select a magnetic domain and nondestructively respond to the magnitude of the magnetic flux for the chosen magnetic domain, producing an electrical output signal corresponding to the magnetic flux for the chosen magnetic domain.
    Type: Grant
    Filed: April 8, 1994
    Date of Patent: April 2, 1996
    Inventors: Stuart E. Goller, Frank Powell
  • Method for stabilizing polyurethane foam using an additive combination of a phenothiazine and at least one co-stabilizer
    Patent number: 4914137
    Abstract: This invention relates to the stabilization of polyurethane foam by using a combination of a phenothiazine with at least a co-stabilizing effective amount of a compound selected from the group consisting of certain dithiocarbamates, thiuramsulfides, mercaptobenzothiazole, phosphites, phosphonites, phenolic antioxidants, pentaerythritol-tetrakis(beta-laurylthiopropionate), 4,4'-thiobis(2-t-butyl-5-methylphenol) and mixtures thereof.
