Title: Parallel Data Transfer Circuit
Inventor: KAWASHIMA TAKAAKI
IPC: G06F13/28
Filed: 1994-02-23
Abstract: A parallel data transfer circuit wherein processing at a data transfer source circuit is simplified to reduce the time required for transfer and a data storage area of a data transfer destination circuit can be used effectively is disclosed.  A plurality of data register sets for temporarily latching parallel data and a plurality of corresponding flag register sets are provided between a data transfer source circuit and a data transfer destination circuit.       A register designation signal is outputted from the data transfer source circuit to designate a data register into which data should be written.  Only when data should be written into the data register, a flag is placed into a corresponding flag register.  Since the data transfer destination circuit fetches data only of those data registers corresponding to those flag registers in which a flag is held, parallel data can be received without forming a discontinuous empty portion in data storage area of the data transfer destination circuit.

Title: A valve having means for generating a wireless transmittable indicating signal in case of a pressure drop within vehicle tires
Inventor: ACHTERHOLT RAINER
IPC: B60C23/04
Filed: 1994-02-07
Abstract: A valve which includes signal generating means for generating a signal representing a pressure drop occurring within a vehicle tire. The valve includes an absolute pressure sensor coupled to measure the pressure within the tire. A microprocessor is provided which upon activation following operation of the valve stores a value of the electric pressure signal from the pressure sensor in a memory. During operation of the vehicle, the stored reference electric pressure signal is compared with periodic measurements of pressure within the tire. The transmitter is activated at periodic intervals, whenever a given ratio between the compared values and a threshold value exceeds an upper or a lower limit. The system is activated by an acceleration sensor which can detect when the vehicle is moving, thus avoiding power consumption when the vehicle is stopped.

Inventor: LIN CHIH-JEN
IPC: G01R31/3185
Filed: 1994-03-16
Abstract: The testability of a near-acyclic circuit (14) can be enhanced by the addition of one or more control points (36) and observation points (34) to allow for increased observability and controllability of selected nodes (28). The control points (36) and/or test points (34) are added by first computing the controllability, observability and fault detection probability at each node. A fault is then selected. If either the controllability or observability for such fault is not inside a prescribed value range, and the fault detection probability is below a prescribed value, then either a control point (36) and/or an observation point (34) may be added.

IPC: H04M1/53
Filed: 1994-05-26
Abstract: Suite à une certaine dérèglementation de l'interurbain, au Canada, plusieurs compétiteurs se font la lutte, sur la même ligne téléphonique. Pour profiter de cette compétition, le consommateur est contraint à modifier ses habitudes ou comportements, à l'égard du téléphone. D'une part, il doit composer une longue séquence de chiffres (17 au minimum), ou d'autre part, utiliser le logiciel que Bell Canada installera, sous peu, sur son réseau, et qui évitera les premiers inconvénients cités (référence: Magazine Affaires Plus, février 94, pp 35-36). Cependant, tous les compétiteurs seront soumis à ce moule. La présente invention est un appareil que, lorsqu'installé entre un téléphone et la ligne téléphonique, intercepte les appels interurbains, composés à même ce téléphone. Ces appels interceptés sont alors réacheminés vers un ou plusieurs compétiteurs, soit par la même ligne téléphonique, soit par un autre "média" de communication : une autre ligne téléphonique, le câble, diverses ondes (radio, courtes, longues, etc.) ou par technique cellulaire.

Le récepteur effectue une démodulation du signal reçu et combine chaque séquence avec un échantillon identique à celui utilisé pour le codage basse-fréquence au niveau de l'émetteur pour reconstituer les différents blocs. L'invention permet de réaliser un étalement de spectre basse-fréquence d'un signal à transmettre.

Title: Ducting for an external gas turbine topping combustor
Inventor: DOWDY THOMAS E
IPC: F02C7/16
Filed: 1995-04-27
Abstract: A gas turbine power plant having a pressurized fluidized bed combustor and an external topping combustor. A cylindrical duct and a toroidal duct direct the flow of hot gas from the topping combustor and distribute it around the circumference of the turbine inlet.  The walls of the duct are cooled by water or steam.  The walls are formed by tubes, having cooling fluid passages formed therein, that extend between inlet and outlet manifolds.  Elongated plate sections connect each tube to an adjacent tube so as to form a continuous gas barrier.  If the walls are water cooled, the water that flows through the tubes for cooling is subsequently directed to a heat recovery steam generator, in which it is converted to steam for expansion in a steam turbine.  If the walls are steam cooled, the steam is first generated in the heat recovery steam generator and then at least partially superheated by flowing through the walls.
