Title: Method and system for extinguishing fire in an enclosed space
Inventor: GRABOW THOMAS
IPC: B64D13/00
Filed: 2001-09-18
Abstract: A system for suppressing fire in an enclosed space, e.g. an aircraft cabin or freight compartment, includes nitrogen tanks and/or generators to rapidly supply a limited quantity of nitro- gen with a high flow rate, and a membrane system to supply an essentially unlimited quantity of nitrogen at a lower supply rate for a long duration. The membrane system includes a selectively permeable membrane that separates nitrogen gas from ambient environmental air that is supplied into the membrane system. Once a fire is detected, nitrogen is supplied from the nitrogen gas tanks and/or generators at a high rate to rapidly increase the nitrogen concentration and establish a reduced oxygen concen- tration (e.g. 12 vol.%) in the enclosed space. Then, nitrogen is supplied from the membrane system at a reduced rate for a long duration to maintain the reduced oxygen concentration in the enclosed space until the fire is extinguished by oxygen starva- tion.

Abstract: A drive unit for a press uses an oil shear brake and an oil shear clutch which are located axially along the output member of the drive unit. A multiple piece piston moves between a brake applied/clutch disengaged position to a brake released/clutch engaged position under the influence of a hydraulic pressure. Cooling and lubrication oil is provided to the drive unit through the output member and lubricating oil is received from the drive member through a stationary support member. An adjustment member is capable of adjusting the gap between the piston and the clutch and brake units in order to eliminate any overlap between these two units.

Abstract: L'invention concerne un système et un procédé de télécommunications permettant la mise en oeuvre d'un protocole de retransmission semi-fiable utilisant à la fois une demande de répétition automatique (RQ) à répétition sélective et une segmentation et un assemblage de paquets de données. Le nouveau protocole de retransmission semi-fiable comprend un déclenchement par temporisateur (300) d'une temporisation de retransmission (290) pour des protocoles de retransmission, ce qui permet à la temporisation de retransmission (290) de devenir insensible aux variations dans le débit de la voie. De plus, la temporisation de retransmission (290) peut être définie sur la base du temps maximum permissible pour la retransmission de paquets (215) de données altérées par interface hertzienne (240). Pour chaque paquet (215) de données reçu, un temporisateur (300) contrôlant le temps de transmission du paquet (215) de données est initialisé. Si le temporisateur (300) fait s'écouler le temps du paquet (215) de données, ce paquet de données est marqué comme étant rejeté dans l'émetteur, et une demande est envoyée au récepteur afin d'assurer que les transmissions portant ce paquet de données sont rejetées dans le récepteur.

Filed: 2000-06-15
Abstract: A control of an instantaneous flow-through fluid heater system (1000) that incorporates a logic control method providing modulation of power in small steps to a plurality of heating elements (5) retaining responsiveness to closed-loop control needs without inducing light flicker. The life of the coils of heating circuit electromechanical relays are extended by energizing the coils with a pulse-width-modulated drive decreasing in duty cycle and thus the latent coil heat when an increase in mains voltage is sensed. The life of the contacts of same relays are extended by inhibiting heating element triac drive immediately upon sensing loss of relay coil power, such as by an over temperature limit switch (8) opening, thus ensuring that relay contacts open with zero heating element current.

Abstract: A method and apparatus related to a communication system in which a plurality of remote units encode data bursts using a predetermined codeword set and transmit the encoded data bursts to a hub station over a multiple-access channel. When the hub station receives a data burst from one of the remote units, the hub station demodulates the received data burst and correlates the received data burst with each codeword within the predetermined codeword set to determine which codeword has the maximum correlation. The hub station uses the correlation to derive a timing synchronization signal and/or a carrier frequency adjustment signal to be sent back to the remote unit. The signals provide information to the remote unit to synchronize its timing or adjust its carrier frequency for transmitting subsequent data bursts. The hub station may also use the correlation to estimate a signal-to-noise ratio.

Abstract: Sy-0 is a late-flowering Arabidopsis ecotype. Genetic analysis has revealed the requirement of dominant alleles at four loci for the establishment of flowering in Sy-0.  These have been identified as FRI, FLC, and two novel flowering loci designated ARTI and ART2 (Aerial Rosette 1 and 2). FRI and FLC are repressors of flowering previously identified from late-flowering Arabidopsis accessions. FRI is an activator of FLC expression. The present invention provides genetic identification and use information for ART1 and ART2. Genetic interaction studies show that ART1 and its enhancer ART2 activate FLC to repress flowering through a pathway that is independent of FRI, and independent of the autonomous and vernalization pathways. Thus, ART1 and ART2 delineate a novel flowering sub-pathway that interacts with the FRI-activated pathway at or upstream of FLC. ART1 has been localized to a l5kb genomic region and maps l4cM proximal to FLC on chromosome V.
