Title: Coupe-circuit a resistance accrue au choc
Inventor: LARSON BRETT EUGENE
IPC: H01H71/52
Filed: 1997-03-31
Abstract: La présente invention concerne un ensemble coupe-circuit constitué d'un socle, d'un couvercle, et d'une manette de commutation conçue pour résister à une force appliquée à un levier de la manette de commutation. En fonctionnement normal, la manette pivote sur des pivots de petit diamètre reçus dans des paliers en fente allongée. Lorsqu'on donne par inadvertance un coup sur la manette, par exemple lorsque quelque chose tombe sur la manette, les pivots coulissent dans les paliers en fente allongée. La force y est alors supportée par des moyeux de grand diamètre qui entrent en contact avec des surfaces de paliers correspondantes. Cela évite d'arracher les pivots à l'occasion de tels incidents, ce qui serait susceptible d'endommager le coupe-circuit.

Title: Continuous flow chemical heat pump
Inventor: TERNAN MARTEN
IPC: F24V30/00
Filed: 1998-03-16
Abstract: A continuous flow chemical heat pump system is described which can be used for heating, refrigeration or for the two simultaneously.  The system includes a decomposition reactor and synthesis reactor.  Flow means are provided for moving a slurry containing particulate solids in a flow cycle through the decomposition reactor, then transferring to the synthesis reactor, through the synthesis reactor and then back to the decomposition reactor to repeat the cycle in a continuous manner.  Heating means are provided for heating the slurry passing through the decomposition reactor to decompose reacted solids of the slurry to release a reactive gas and leave a slurry containing unreacted solids.  The reactive gas is passed through a condenser in heat exchange flow with a cool fluid to cool the gas and at least partially condense it to a liquid phase.  Thereafter, the reactive gas is passed through a pressure reducing valve to reduce both the pressure and temperature.  It is then passed through an evaporator to evaporate the reactive gas to the gas phase by transferring heat to a warm refrigerant stream thereby producing a cooled refrigerant stream.  The evaporated reactive gas passes through the synthesis reactor in counter current flow contact with the slurry containing unreacted solids to thereby form a slurry containing reacted solids which is transferred back to the decomposition reactor.

Title: Mutant plasminogen activator-inhibitor type 1 (pai-1) and uses thereof
Inventor: STEFANSSON STEINGRIMUR P
IPC: A61K38/00
Filed: 1997-04-11
Abstract: Mutants of the human PAI-1 protein are described which are inhibitors of neutrophil elastase or are inhibitors of vitronectin (Vn)-dependent cell migration. These mutants preferably comprise one or two amino acid substitutions in the reactive center loop of PAI-1, particularly at positions 331 and 346 of the mature protein. These mutants are notable in being resistant to inactivation by elastase, having high affinity for Vn, or both properties. These mutant proteins as pharmaceutical compositions are used to inhibit elastase in a subject, thereby treating a number of disorders associated with elastase activity, most notably emphysema, ARDS, inflammatory lung injury and cystic fibrosis. The mutants which interact with Vn are used to inhibit cell migration in a subject, thereby treating diseases or conditions associated with undesired cell migration and proliferation, particularly of smooth muscle cells. Such conditions include atherosclerosis, post angioplasty restenosis, fibrosis associated with chronic inflammation or chemotherapy, tumor invasion and metastasis and conditions in which angiogenesis is pathogenic. Also disclosed are peptides of such mutant proteins, mutant-specific antibodies, nucleic acid molecules, particularly DNA, encoding the mutant protein and host cells transformed by such nucleic acids.

Title: Thermal trip unit with magnetic shield and circuit breaker incorporating same
Inventor: KOLBERG KENNETH D
IPC: H01H71/12
Filed: 1998-04-14
Abstract: A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated magnetically permeable member mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated magnetically permeable member which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated magnetically permeable member of the armature extends. A radially enlarged slug on the free end of the elongated magnetically permeable member of the armature is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature into the solenoid coil. This opposing force increases as the initial gap increases, placing the slug closer to the magnetic frame, so that a greater range of trip currents can be selected despite limited room for armature travel. A gap in the magnetic frame prevents short circuiting the magnetic field where the few turns of a large gauge coil wire produce an unsymmetrical winding. A magnetic shield protects the bimetal from deformation during high current short circuits.
