Title: Methods for manufacturing foam material including systems with pressure restriction element
Inventor: XU JINGYI
IPC: B29C48/38
Filed: 2000-03-30
Abstract: The invention provides systems, methods, and articles useful in the production of foams, and, in particular microcellular foams. The systems include a restriction element (35) that reduces the backflow of polymer melt in an extruder while polymeric material is injected into a mold (37) or ejected from a die. The restriction element is positioned upstream of a blowing agent injection port (54) to maintain the solution of polymer and blowing agent in the extruder above a minimum pressure throughout an injection or ejection cycle, and preferably above the critical pressure required for the maintenance of a single-phase solution of polymer and blowing agent. The systems can be used in injection molding, blow molding, or in any other processing techniques that include injection or ejection cycles. In some embodiments, the systems utilize reciprocating screws for injection or ejection. In other embodiments, the systems include an accumulator connected to an outlet of the extruder, in which a plunger moves to inject polymeric material into a mold or eject polymeric material from a die.

Title: Metabolic calorimeter employing respiratory gas analysis
Inventor: WEINTRAUB JEFFREY C
IPC: G06F19/00
Filed: 2000-08-02
Abstract: An indirect calorimeter for measuring the metabolic rate of a subject is provided, which includes a respiratory calorimeter (10) configured to be supported in contact with the subject, passing inhaled and exhaled gases as the subject breathes. A flow pathway (22) is operable to receive and pass inhaled and exhaled gases having a first end in fluid communication with the  respiratory connector (20) and a second end is in fluid communication with a  source and sink for respiratory gases. A flow meter generates electrical signals as a function of the instantaneous flow volume of inhaled and exhale d gases passing through the flow pathway. A component gas concentration sensor  (84) generates electrical signals as a function of the instantaneous fractio n of a predetermined component gas in the exhaled gases as the gases pass through the flow pathway. As the subject breathes through the calorimeter (10), a computation unit (96) receives electrical signals from the flow mete r and the component gas concentration sensor (84), calculating at least one respiratory parameter.

Title: Electro-mechanical system for determining key cuts for tumbler and wafer locks
Inventor: WRIGHT JESSE M
IPC: E05B19/20
Filed: 2002-04-09
Abstract: A system for decoding locks having a sequence of spring-urged sliding members such as tumbler pins or wafers includes a probe device having the general contour of a key having a head portion and a straight shank fabricated of electrically insulative material and terminating in a tip portion having an oblique ramp surface. A series of spaced apart electrical conductors embedded within the shank in parallel relationship extend from the head portion to the ramp surface where they emerge as electrical contacts. An electrical circuit which includes an electronic monitoring and display apparatus detects when a given sliding member touches a most distant electrical contact, thereby representing a travel distance. The travel distance is correlated with a particular pin or wafer to produce the key code for the lock.
Patent CA-2381469-A1 (CA)
Title: Heat transfer from a source to a fluid to be heated using a heat driven loop
Inventor: LANGE JACK
IPC: F28D15/02
Filed: 2002-04-11
Abstract: Oil in a storage tank is heated to reduce viscosity and/or to enhance separation of water/oil emulsion by providing one or more elongate conduit within the storage tank in the form of a loop extending from an inlet manifold across the tank and returning to an outlet manifold. The inlet manifold is connected to an evaporator section at a heat source and the outlet manifold acts as a return of the condensate from the condensation section of the conduit within the tank. A heat transfer fluid medium within the closed system is arranged to boil to form a vapor in the evaporation section and such that release of heat from the condensation section to the fluid to be heated causes the vapor to condense to liquid in the condensation section. The conduit forms a loop and back flow in the loop is prevented by providing a trap of liquid in the conduit at a position adjacent to or at the evaporation section. The flow around the loop at high speed sufficient to carry all condensate forwardly is caused solely by application of energy to the system by the heat source without mechanical pumping. Inert gases are collected immediately upstream of the trap and can be purged therefrom. The fuel supply can be modulated or cycled during a start up phase by an over-limit sensor which maintains heating at a controlled level while the oil is resistant to absorbing heat.
