Abstract: ' The run-flat tire of this invention includes a pair of bead regions,  a crown region with a tread and a tread reinforcing package including a cap ply and self supporting sidewalls between each bead region and the crown region.  An innerliner ply maintains air within the inflated tire.   The self supporting sidewalls each include a first crescent-shaped reinforcing member, an inner carcass layer, an inner sidewall supporting complex and an outer sidewall and bead protecting complex.  The supporting sidewalls effectively have a plurality of crescent-shaped reinforcing members and a plurality of carcass layers.  The sidewall supporting complexes are realized by providing first and second partial carcass layers along with a  filler  rubber  portion  and  a  second  crescent-shaped reinforcing member, which can be formed by a separate tire building operation.  The sidewall protecting complexes can be formed in a similar operation.   The run-flat tire of this invention can be realized within standard production rates for building tires.           The inflated vs. deflated performance tradeoffs in ride comfort, handling, radial stiffness and endurance of the tire  are  substantially maintained with  improved  mass  and rolling resistance over previous run-flat tires.   This is accomplished with a run-flat tire having relatively small weight increases over a standard tire and with a rim that can be used interchangeably with the standard tire.

Title: Closed system for volatile organic compound recycling
Inventor: BUCHHOLZ LORETTA P
IPC: B05B15/12
Filed: 1996-03-28
Granted: 2006-05-16
Abstract: In the method and system of the instant invention, volatile organic compounds (VOCs) liberated in the course of solvent-based painting of a workpiece, are recovered. The atmosphere within a closed spray-booth (10) is maintained at a fixed humidity such that vaporized water, supplied in the form of steam or nebulized water vapor, acts as a carrier for VOCs liberated in the course of spray painting or heat curing of a workpiece. The VOCs may be recovered continuously, including during the spray-painting or heat curing of the workpiece. The VOC laden, humidified air is circulated through a condenser (14) such that VOCs dissolved in the water vapor condense and are directed to a recovery means. The water and solvent are separated, recovered and purified for re-use or placed in an appropriate container (15) for disposal, thereby eliminating the usual practice of expelling VOC laden air into the atmosphere.     The system is provided with a flame-free heat source (17) to cure the painted workpiece and to guard against the danger of explosion.

Title: Transcoder with prevention of tandem coding of speech
Inventor: LEHTIMAKI MATTI
IPC: H04W4/18
Filed: 1996-04-11
Granted: 2006-10-10
Abstract: The invention relates to a transcoder (TRCU1, TRCU2) having means for preventing tandem coding of speech in a mobile to mobile (MS1, MS2) call within a mobile communication system which employs a speech coding method for reducing transmission rate on the radio path. The transcoder (TRCU1, TRCU2) comprises a speech coder (52, 73) which encodes the speech signal into speech parameters for transmission to a mobile station, and decodes the speech parameters received from the mobile station into a speech signal according to said speech coding method, as well as a PCM coder (54, 72) for transmitting an uplink speech signal to and for receiving a downlink speech signal from a PCM interface in the form of PCM speech samples. In addition to the normal operation, the transcoder transmits and receives speech parameters through a PCM interface in a subchannel formed by least significant bits of the PCM speech samples. Thus, it is possible to prevent tandem coding but at the same time maintain the standard PCM interface and the signalling and services associated thereto.

The signal combination determining circuit selects the same number as that of the spread spectrum demodulators out of the multipath signals, which minimizes a drop in power level of a diversity combined signal outputted from the diversity combiner according to the determined correlation. The demodulator phase control circuit controls phases of demodulating operations of the spread spectrum demodulators to demodulate the selected multipath signals, respectively.
Patent CA-2222096-C (CA)
Inventor: MARTINS PAULO ANTONIO FIRME
IPC: B44B5/00
Filed: 1997-02-10
Granted: 2004-04-27
Abstract: The invention deals with a technology for minting coins and medals. The technology is based on the utilization of metal blanks with similar diameters, one being very thin (hereafter named as the foil), joined together by mechanical means during the impartion of the surface details by the minting dies. The technology requires the design and manufacture of a special geometry in the edge of the thicker disk in order to make possible assembly of the metal blanks. The proposed technology is based on a multi-stage manufacturing process consisting of three cold metal forming operations (preforming, rimming and coining) and one intermediate annealing treatment. The first metal forming operation ensures the preforming of the thicker disk blank, hereafter named as the disk. The second metal forming stage is the rimming operation in which the preformed disk is bent along its diameter in order to generate a suitable profile for subsequent assembly with the foil. The third metal forming stage is a coining operation in which the metal blanks (disk and foil) are assembled together, by locking the foil into the rimmed edge of the disk, during the imprint of the surface details. The annealing treatment is to be performed before the coining operation. The goal is to restore the initial ductility of the disk prior to the final coining stage.

Title: Electrode for plasma generator the generator comprising same and process for treatment of solidifying liquid metal
Inventor: ROSEN RAN
IPC: H05H1/34
Filed: 1997-01-16
Granted: 2004-05-18
Abstract: A main electrode for plasma arc generator, a generator comprising same and a process for treatment of solidifying liquid metal by the mentioned generator, wherein the main electrode in association with a counter electrode provides a two-rail structure capable of generating a plasma arc discharge displaceable along a closed path uninterruptedly. The uninterrupted movement of the arc discharge is achieved by a specific design of the main electrode. The electrode comprises an essentially tubular body having a first rim usually connected to a d.c. power source via at least one connector site, and a second, working rim serving for the electric arc discharge. The tubular body is divided by at least one slot (gap) associated with one connector site and extending between the first and second rims so that it forms at the second rim region a second rim gap. Two sides of the second rim gap are an arc transmitting and an arc receiving zones, respectively. Mutual positions of these two zones and the associated connector site are such, that when the arc column is created and displaces along the second rim, it will always be transmitted from the transmitting zone to the receiving zone at a location positioned downstream from the projection of the associated connector site to the second rim (in respect of the direction of the plasma arc movement). Owing to this arrangement the arc column will cross the second rim gaps uninterruptedly.
