Des évidements (15) à chaque coin s'étendent de chaque coin d'une ouverture interne vers un bord périphérique du coussin pour fournir une partie en forme de coin des chambres latérales. Dans un des modes de réalisation, une paire supplémentaire d'ouvertures internes facilite l'appui d'une paire de chambres gonflables supérieures (20) reliées aux chambres terminales sur la face supérieure de l'article. Dans un autre mode de réalisation de la présente invention, la chambre protégeant la partie supérieure de l'article comporte une seule chambre gonflable qui se plie autour de la face supérieure de l'article. La chambre supérieure possède dans son milieu une ouverture interne (122) formée par une soudure. Des parties de chaque feuille thermoplastique qui restent après que le coussin a été coupé et adapté pour retenir un article mince s'étendent vers l'intérieur à partir de la soudure.

Abstract: A valve for regulating pressure intermediate suction and discharge pressure in ascroll compressor having an axially sealing interface between a fixed and orbiting scroll member through which the axial relationship between the scroll members may be controlled. The scroll members are axially biased together by refrigerant gas at a pressure intermediate the suction and discharge pressures and which is disposed in an intermediate pressure chamber defined in part by a generally planar surface of the orbiting scroll member. A self-regulating sliding valve, actuated by forces exerted on axial valve surfaces by suction, discharge and intermediate gas pressures, controls the amount of intermediate gas pressure in the intermediate gas pressure chamber. Anannular groove in fluid communication with a longitudinal bore within the valve body and which opens to the intermediate pressure chamber is moved between a first position, in which the annular valve groove communicates with a passage to the compressor discharge pressure chamber, and a second position, in which the annular valve groove communicates with a passage to the compressor suction pressure chamber, placing the intermediate pressure chamber in communication with the discharge and suction pressure chambers, respectively. A third position, intermediate the first and second positions, seals the intermediate pressure chamber. Hence the axial engagement force exerted between the fixed and orbiting scroll members is controlled and a constant wrap to face clearance between the fixed and orbiting scroll members is maintained.

Abstract: An apparatus for the controlled heating of a process fluid has a heater, a process fluid vessel containing the process fluid, and a bundle of thermosyphons extending between a burner chamber of the heater and the process fluid inside the vessel for transferring heat from the heater to the process fluid. Burners in the burner chamber are controlled to maintain the bulk temperature of the process fluid T BULK substantially within an operating range defined by preset upper T HIGH  and lower T LOW temperature setpoints. The burners can be turned on to maintain an outside metal temperature T EVAP of the evaporator ends of the thermosyphons above a preset dew point temperature T DEW to prevent corrosion. The burners can also be shut down if an outside surface temperature T OD of at least one of the condenser ends of the thermosyphons extending into the vessel exceeds a predetermined setpoint temperature T ALARM. Different configurations of condenser ends of the thermosyphons in the vessel may be utilized to enhance heating the process fluid.     The vessel and heater are separated and sealed from each other by a sealed chamber encasing the thermosyphons, which may also be used to preheat incoming combustion air for the burners.

Title: Collarless circularly magnetized torque transducer having two phase shaft and method for measuring torque using same
Inventor: GARSHELIS IVAN J
IPC: G01L3/10
Filed: 1998-10-21
Granted: 2003-01-28
Abstract: A magnetoelastic torque sensor (2) for providing an output signal (24) indicative of the torque applied to a member about an axially extending axis of the member (11), comprising a member which is unitary and of generally homogeneous chemical composition, the member comprising separate magnetically active (ABC) and magnetically substantially passive regions. A first magnetoelastically active region in the member is magnetically polarized in a single circumferential direction and possesses sufficient magnetic anisotropy to return the magnetization in the region, following the application of torque to the member, to the single circumferential direction when the applied torque is reduced to zero, whereby the magnetoelastically active region produces a magnetic field varying with the torque. Magnetic field sensors (6) are mounted proximate to the magnetoelastically active region and oriented with respect thereto to sense the magnitude of the magnetic field at the sensors and provide the output signal in response thereto. The magnetoelastically active region of the member is formed of a polycrystalline material wherein at least 50 % of the distribution of local magnetizations lie within a 90~ quadrant symmetrically disposed around the single circular direction and has a coercivity sufficiently high to prevent irreversible loss of the magnitude of the circumferential polarization.

Title: Method for solving the music-on-hold problem in an audio conference
Inventor: HORN DAVID N
IPC: H04M3/20
Filed: 1999-06-21
Granted: 2003-03-25
Abstract: A solution to the music-on-hold problem associated with audio conference calls. The music on-hold-problem occurs when a conferee having music-on-hold puts the conference call on hold, resulting in a continuous stream of music being transmitted to the other conferees. Such a conferee is called an offending conferee. The solution presented herein is to prevent music-on-hold signals emanating from an offending conferee from being passed through an audio conference bridge to the other conferees. This is accomplished, in particular embodiments, by directing a merging/summing subsystem of the audio conference bridge to temporarily stop combining audio emanating from the offending conferee from being combined or merged onto audio channels through which the other conferees communicate on the audio conference. Once the music-on-hold is terminated, the offending conferee can rejoin conference call by sending a signal that directs the merging/summing subsystem to resume the combining of audio signals emanating from the offending conferee onto the audio channels of the other conferees.

Abstract: A technique for producing soldering iron tips entails cutting clad wire into a plurality of segments, each segment comprising a core of material (such as copper) and an outer protective layer (such as stainless steel, Ni, Cr, or alloy thereof). Each clad wire segment is then shaped into a soldering iron tip by a cold or hot heading process, or other metal forming process. In the finished tip, the protective outer layer is disposed behind the working area of the tip, and serves to reduce the corrosion of the tip, and to improve the electrical conductivity between the tip and the soldering iron handle. A heater element can be formed at one end of the soldering iron tip from the same clad wire segment used to produce the tip itself, thereby ensuring good thermal transfer properties between the heater element and the tip. The invention also pertains to a technique for forming a protective outer layer on the working area of the tip. The technique comprises stamping caps from a thin strip or sheet of protective material, such as iron. More specifically, the caps are stamped out of the sheet using a die having a shape which resembles the shape of the working area of the soldering tip. The caps formed in this manner are then inserted over the ends of the tips, and attached thereto by applying brazing material to the formed cap or to the strip of material prior to forming the cap.
