Granted: 1992-07-07
Abstract: ABSTRACT OF THE DISCLOSURE        A container closure formed from a thermoplastic polyolefin, e.g. polypropylene, which  has  been  molded  and  adheres simultaneously to a coated foil, e.g. an aluminum insert, to which a conventional plastisol gasketing compound may be adhered to provide a hermetic container seal under hot fill and retort conditions.   In order to facilitate adhesion to both the polypropylene closure panel and the PVC plastisol gasketing compound, a dead soft aluminum foil web was first coated on one side with an organosol utilizing a gravure coater, after which the coated web was passed through an oven. The partially coated web was then coated with a primer dispersion again utilizing a gravure coater, after which the coated web was passed through  a second  oven.   A  layer  of polypropylene homopolymer was applied to the primer and inserts were die cut from the resultant web.  The inserts were incorporated in a closure injection molding apparatus and a plastic closure injection molded thereabout. Thereafter a plastisol gasket compound was applied to the exposed surface of the insert and fused by convection and/or induction or dielectric heat.

Abstract: Title:  IMPROVED BACULOVIRUS EXPRESSION SYSTEM CAPABLE OF     PRODUCING FOREIGN GENE PROTEINS AT HIGH LEVELS            ABSTRACT OF THE DISCLOSURE     A baculovirus expression system capable of producing foreign gene proteins at high levels.  The system involves the production of a recombinant baculovirus containing a modified foreign gene between the polyhedrin gene promoter region and the transcription termination signal of the polyhedrin structural gene.  The modified foreign gene comprises a putative ribosome binding site immediately upstream of the foreign gene coding sequence, i.e. without any intervening non-coding sequences.  The putative ribosome binding site is preferably properly positioned without the intervening sequences by a crossover linker mutagenesis procedure before the modified foreign gene is introduced into the virus.  The putative ribosome binding site preferably comprises at least the final four nucleotides of the sequence ACCTATAAAT immediately upstream of the translation initiation codon (ATG) of the foreign gene.  The system is capable of producing foreign gene proteins (when insect cells are infected with the recombinant virus) at high levels, even in the case of those genes which expressed only at low or intermediate levels in prior recombinant baculovirus systems.

Abstract: A double pump adapted for use as an artificial heart includes two ventricle-simulating chambers that are provided with respective inlets and outlets having valves incorporated therein and that are separated by a common partitioning wall structure. The wall structure has sections that are driven away from each other to reduce the volumes of respective ventricle chambers and expel liquid from the chambers through the outlets. The wall structure can also move laterally in response to differences in pressure between the chambers and hence change the volumetric ratio between them. This ensures a balanced action between the two halves of the heart- simulating pump during a systole phase and a diastole phase. The link mechanism is actuated by a cord through a motor, although only in one direction in the pressure phase, and hence the aforementioned changed volumes are readjusted primarily through the pressure exerted by the inflowing fluid. The pump may also include a variable volume atrium-simulating chamber communicating with the inlet to each ventricle-simulating chamber and having volume that is controlled in part by an externally acting gas pressure that varies in accordance with changes in the volumes of the ventricle chambers.
