Title: Process for producing a reduction gas for reduction of metal ore
Inventor: WURM JOHANN
IPC: C21B13/00
Filed: 1997-07-09
Abstract: In a method for producing a hot CO- and H2-containing reducing gas serving for the reduction of lumpy metal ore, in particular iron ore, the reducing gas is formed in a gasification zone (8) by a gasification of carbon carriers, in particular coal, taking place under the supply of oxygen and subsequently is cooled down to a reducing-gas temperature favorable to the reduction process. In order to produce a thermodynamically more stable reducing gas, the reducing gas by the addition of H2O and/or CO2 - in order to prevent the Boudouard and heterogeneous water-gas reaction and a resultant heating of the reducing gas - is converted to a reducing gas that is thermodynamically more stable at the reducing-gas temperature.

Abstract: A minimum recirculation flame control (MRFC) solid fuel nozzle tip (12) that is particularly suited to being cooperatively associated with a pulverized solid fuel nozzle (34) of a firing system of the type employed in a pulverized solid fuel-fired furnace (10). The MRFC solid fuel nozzle tip (12) when so employed is operative to minimize low and negative, i.e., recirculation, velocity regions of the exit plane of the MRFC solid fuel nozzle tip (12), and to reduce available deposition surface on the MRFC solid fuel nozzle tip (12), and to vary the nozzle tip (12)/solid fuel nozzle (34) thermal conditions to keep the "hot" solid fuel particulate matter from depositing on available metal platework surface of the MRRC solid fuel nozzle tip (12). The MRFC solid fuel nozzle tip (12) includes fuel air shroud means (46), primary air shroud means (48) located within the fuel air shroud means (46), fuel air shroud support means (50) operative for supporting the primary air shroud means (48) relative to the fuel air shroud means (46), and splitter plate means (52) mounted in supported relation within the primary air shroud means (48).

Abstract: A baggage handling system includes a plurality of baggage trays for carrying baggage and a conveyor for transporting the trays at a given speed. A diverter selectively removes baggage from the conveyor and positions the baggage on an accumulator.  An unloader is provided to unload the baggage from the accumulator. The accumulation in one mode slows baggage as received from the conveyor and presents the slowed baggage to an unloading device at a generally constant rate, such a rate being dependent of the rate at which the baggage is diverted from the conveyor. The unloader uses a tipping mechanism employing wheel guides an and actuator for gentle tipping of the baggage from the accumulator to another zone such as a make-up area in an airport baggage handling system.

Abstract: Cette invention concerne un procédé et un dispositif qui permettent de dériver le courant dans un circuit électrique (1), tel qu'un circuit d'abonné comprenant une transmission bifilaire équilibrée. Ce circuit comprend un utilisateur (3) qui a des besoins variables en matière de tension, ces besoins étant gérés en fonction de la caractéristique d'alimentation du dispositif et de la résistance dans la transmission bifilaire (A, B, L). Les besoins en tension de l'utilisateur sont renvoyés par l'intermédiaire d'un signal de référence (U¿REF?) à l'entrée d'un circuit régulateur de tension (2), lequel va envoyer à l'utilisateur une tension d'actionnement (V¿BAT2?) qui est fonction de la valeur du signal de référence. Le circuit régulateur de tension (2) reçoit une tension d'alimentation (V¿BAT?), la tension du régulateur (V¿0?) étant déterminée en calculant la différence entre la tension d'actionnement (V¿BAT2?) et la tension d'alimentation (V¿BAT?). Un dispositif externe (8), qui est monté en parallèle au circuit régulateur de tension et qui peut consister en une résistance, est connecté de manière à dériver toute puissance excédentaire générée dans le circuit régulateur de tension. Cette dérivation se fait à l'aide de la totalité ou d'une partie du courant d'alimentation de l'utilisateur qui est amené à la résistance externe, la totalité ou une partie de la puissance excédentaire y étant ensuite libérée.

Title: An arrangement for synchronization of multiple streams of synchronous traffic delivered by an asynchronous medium
Inventor: PETTY NORMAN W
IPC: H04Q11/04
Filed: 1999-11-03
Abstract: An ATM cell constructor of an ATM transmitter assembles a stream of frames of constant bit-rate traffic received on a listen TDM bus into cell payloads using ATM adaptation layer 1 (AAL1 ). Once every eight cells, the AAL1 structured data transfer (SDT) cell constructor layer introduces a one-octet SDT offset pointer into the payload. This pointer designates traffic-block (TDM frame) boundaries. The payload with an attached ATM header forms an ATM cell, and the constructor transmits a stream of the ATM cells, carrying traffic of one wideband channel, to a receiver. A receiver receives one or more streams of the ATM cells from one or more transmitters. During each frame interval, an ATM cell deconstructor of the ATM receiver disassembles a block's worth of traffic from a received ATM cell of each received stream, assembles the disassembled traffic from every stream into a TDM frame, and transmits the frame on a talk TDM bus. In response to commencing to disassemble a whole block's worth of traffic from an ATM cell that includes the SDT offset pointer, the deconstructor adjusts the disassembling to commence the disassembling of the whole block's worth of traffic at the block boundary pointed to by the SDT offset pointer, thereby aligning frames on the talk TDM bus with the frames on the listen TDM bus. The listen and talk TDM buses are thereby synchronized with each other.

Title: System and method to efficiently transmit common channel signals in a switching network
Inventor: ZAHARYCHUK JOHN
IPC: H04Q3/00
Filed: 2000-01-27
Abstract: The present invention discloses a system and method to efficiently transmit common channel signaling (CCS) data in a switching network. The system includes a transmitting access device, a receiving access device, and a network coupling together the access devices. The transmitting access device receives CCS data from an attached private branch exchange (PBX). The transmitting access device examines the CCS  data to determine whether the data is relevant or irrelevant. If the CCS data is relevant, the transmitting access device constructs a packet or frame to hold the CCS data, and routes the constructed packet or frame through the network to a receiving access device. If the CCS data is irrelevant, the transmitting access device discards the data without routing it to conserve network bandwidth.

IPC: H04B1/04
Filed: 1998-07-15
Abstract: A system and method for transmitting cellular signals has linear power amplifiers mounted on a cellular tower within a tower circuit. The linear power amplifiers provide the primary amplification of the signals which are transmitted by the antennas on the tower. By moving the amplifiers from a base station to the tower circuit, the system and method can employ less-expensive and more-reliable amplifiers and need not employ high-cost low-loss feeder lines. The tower circuit also includes a modulator for transmitting status signals down to the base station. The base station includes a demodulator for receiving the status signals and a control circuit for placing a switching circuit in a desired one of a plurality of modes based on the status of the tower circuit. The switching circuit, in a first mode, passes radio signals from combiners to their respective feeder lines and thus to their respective amplifiers and antennas when all transmission paths are operational. If a fault occurs along one or more transmission path, the switching circuit combines the radio signals from the combiners associated with the faulty amplifiers with the radio signals associated with an operational antenna and directs the combined set of radio signals to the operational antenna. In this manner, the system and method provide a redundancy path whereby a fault in the tower circuit does not result in any transmission loss.
