Inventor: MCELDOWNEY CARL
IPC: B65D8/04
Filed: 1992-01-28
Abstract: A sheet metal end closure for a container of pressurized products, which closure includes a substantially planar central panel, a countersink around the central panel, a chuckwall around the countersink and a seaming flange around the chuckwall.  It further includes an annular downwardly stepped portion between the central panel and the countersink and a coined zone in the panel radius which connects the stepped portion to the countersink.  The invention includes a method and apparatus for forming such a sheet metal closure wherein the panel radius between the central panel and the countersink is coined around at least a portion of the circumference of the central panel before the periphery of the central panel is reformed.  In accordance with this invention, a major portion of the central panel is moved away from the countersink by depressing the outer peripheral portion of the central panel along with the countersink and chuckwall.  Depressing the peripheral portions of the end shell with respect to the central panel increases substantially the height of the central panel and uses the slack or loose metal created by the coining operation.  This puts the metal in the end shell substantially into tension and helps reduce, or eliminates, central doming of the end shell due to internal pressure in a container on which the shell is seamed.

Title: Non-replicating recombinant-made retroviral particles used as antiviral agents and immunogens
Inventor: HAFFAR OMAR K
IPC: A61K39/00
Filed: 1990-11-20
Abstract: Nonreplicating recombinant-made retroviral particles having structural, morphological and immunological characteristics very similar to those of native human retroviruses are described. The method of the invention involves coexpression of mature retroviral core and envelope structural proteins in mammalian host cells such that the expressed retroviral proteins associate into assembled budding retroviral particles. In a particular embodiment of the invention, nonreplicating recombinant-made HIV-1 particles are produced by coinfecting mammalian host cells with a recombinant vaccinia virus carrying the Human Immunodeficiency Virus Type 1 (HIV-1) gag and protease genes and a recombinant vaccinia virus carrying the HIV-1 env gene. These nonreplicating recombinant-made HIV-1 particles have immunological and morphological characteristics closely resembling those of native HIV-1, are able to block the infectivity of live HIV in vitro, and are highly immunogenic in vivo. The recombinant-made HIV-1 particles of the invention may be used as anti-viral agents and as immunogens in vaccine formulations effective at inhibiting or preventing infection by HIV  and/or the development of the Acquired Immunodeficiency Syndrome.

Title: Vaccines protective against gram-negative bacteremia and endotoxic shock and related diagnosic assays
Inventor: APICELLA MICHAEL A
IPC: A61K39/39
Filed: 1992-06-11
Abstract: Abstract Of The Disclosure The present invention is directed to the development of monoclonal anti-idiotypic antibodies (anti-ids) which mimic a common antigenic determinant on the lipid A portion of the Lipopolysaccharite (LPS) of gram-negative bacteria.  More particularly, the invention comprises the development of hybridomas A4, H9, and H12 which produce monoclonal anti-Ids that mimic a common antigenic determinant on the lipid A portion of the LPS molecule found on a number of different bacterial strains.  The development of the hybridomas was carried out by induction with a monoclonal antibody, 1C9, which recognizes a conserved epitope, that is a target for a bactericidal antibody, or involved in immune clearance mechanisms, and is common to all Enterobacteriaceae gram-negative bacteria.     The anti-Ids contain a protein image of the lipid antigen and are thus capable of stimulating anti-LPS activity. Therefore, the anti-Ids of the present invention may be used as immunogens in vaccine formulations designed to protect against gram-negative bacteremia and septic shock.  In one embodiment of a vaccine formulation in accordance with the present invention, the peptides could be generated based on the identity of the sequences of the idiotopes of anti-Ids.  Alternatively, the DNA encoding the idiotopes which mimic the lipid A antigenic determinant may be used by applying molecular cloning techniques to direct production of the peptides. Additionally, the DNA itself may be incorporated into various vaccine-related vectors for vaccine applications.

Patent CA-2071484-A1 (CA)
Inventor: WHITE BRADLEY E
IPC: G06Q50/00
Filed: 1990-12-14
Abstract: A biosensing system is described which determines whether a measured current is varying in accordance with a predetermined Cottrell current relationship. The system includes a test cell with at least a pair of electrodes which extend into a reaction zone, which reaction zone includes analyte reactants. An analog signal detector, in combination with a microprocessor, take plurality of current measurements between the electrodes over a plurality of succeeding measurement times, after a sample is placed in contact with the analyte reactants in the reaction zone. The microprocessor also stores a plurality of succeeding cpmparison constants which are derived by taking the inverse ratio of the square root of a measurement time divided by the square root of a subsequent measurement time. The microprocessor selects a pair of succeeding measurement times; derives a ratio of the currents measured at those times; and then compares the ratio of those currents with the comparison constant previously derived for the pair of succeeding measurement times. If the comparison indicates that the measured current ratio is dissimilar from the comparison constant, an indication is developed that the current between the electrodes is not varying in accordance with the Cottrell relationship. The plurality of current measurements are also used to calculate total charge transferred, Q. Q can then be used as a second means of calculating the final result.

Filed: 1993-02-25
Abstract: A data demodulator demodulates a differential phase-shift-keying (DPSK) modulated receive signal to produce symbol rate demodulated data.  A phase detection means, delay means, and phase difference detection means connected in cascade detect the phase of the receive signal and generate a phase difference signal having N-phases, in synchronism with respective clock signals. A decision means generates decision data on the basis of a phase range of the phase difference signal, and a decision error computing means computes a decision error on the basis of each phase of the phase difference signal and a corresponding decision phase of the decision data.          Decision error adding means, and respective decision error registers accumulate and store respective decision error sums.  A signal processing means reads out the decision error sum from each of the decision error registers, computes a sampling phase signal by a prescribed computing technique, and outputs a sampling phase signal.  Finally, a sampling means generates the symbol rate demodulated data by sampling a phase of the decision data and the sampling phase signal.
