Title: Apparatus for the recombination of hydrogen in a gas mixture
Inventor: ECKARDT BERND
IPC: G21C19/317
Filed: 1998-01-27
Abstract: The invention relates to a device (1, 1') for recombining hydrogen in a gas mixture, for use in particular in a nuclear power station. During the operation of said device, unintentional ignition of the gas mixture is prevented in an especially reliable fashion.  According to the invention, the device comprises a catalyst system (2), arranged in a housing (4) through which the gas mixture is able to circulate by free convection when the device is operational, to which is assigned a flame retention device (8). A sediment trap (14) is preferably integrated into the flame retention device (8) to reliably prevent hot catalyst particles that have become detached from the catalyst system (2) from exiting against the direction of flow of the gas mixture.

IPC: H04J11/00
Filed: 1997-05-17
Abstract: L'invention concerne un décodeur (200) et un codeur (300) servant, respectivement, à l'extraction d'un sous-ensemble de symboles d'un canal de transmission (333) ou à l'insertion d'un ensemble de symboles dans ce canal de transmission, canal dans lequel M symboles sont émis en tant qu'amplitudes de M porteuses sinusoïdales. Le décodeur (200) récupère K symboles, S¿p?...S¿p+K-1?, à partir d'un signal analogique généré par modulation de M porteuses sinusoïdales pendant une période de trame. Chaque porteuse est modulée avec une amplitude proportionnelle à la valeur de l'un des M symboles, la i?ème¿ porteuse étant modulée par le symbole S¿i?. Les K symboles sont un sous-ensemble contigu des M symboles. Le décodeur (200) comprend un changeur abaisseur de fréquence (201, 211, 202, 212) qui sert à abaisser la fréquence du signal modulé émis dans le canal de communication, pour générer un signal à fréquence abaissée dans lequel les porteuses correspondant à S¿p?...S¿p+K-1? occupent des fréquences commençant à 0. Un convertisseur analogique-numérique (203, 313) génère K échantillons de domaine temporel dans chaque période de trame, à partir du signal dont la fréquence est abaissée. Ces échantillons de domaine temporel sont convertis en K valeurs de domaine de fréquence représentant les symboles S¿p?...S¿p+K-1? par une transformée à chevauchement domaine temporel en domaine de fréquence. Le codeur (300) code K symboles, S?1¿...S?k¿, en tant qu'amplitudes de K porteuses sinusoïdales, les K porteuses sinusoïdales comprenant un bloc contigu de porteuses dans un signal comprenant M porteuses sinusoïdales dont chacune est modulée par un signal présentant une amplitude déterminée par la valeur de l'un des symboles pendant un temps égal à une période de trame. Le codeur (300) inclut une transformée à chevauchement domaine de fréquences en domaine temporel (302, 312) pour générer K échantillons de domaine temporel à partir des K symboles, les échantillons de domaine temporel représentant une porteuse modulée comprenant K porteuses sinusoïdales dont chacune est modulée par un signal ayant une amplitude déterminée par la valeur de l'un des K symboles. Un convertisseur numérique-analogique (304, 314) convertit les K échantillons de domaine temporel en signal analogique. Ce signal analogique subit ensuite une élévation de fréquence de sorte que la porteuse sinusoïdale modulée par S¿1? présente une fréquence égale à la p?ième¿ porteuse des M porteuse sinusoïdale, p étant ?0.

Patent CA-2290842-A1 (CA)
Inventor: MUSCARELLA STEPHEN B
IPC: F04B53/06
Filed: 1999-11-25
Abstract: A new and improved automatic venting back pressure valve is provided in a valve body including a back pressure chamber having a fluid inlet and a fluid outlet. A spring loaded back pressure member covers the fluid outlet which is movable between a normally closed position wherein the back pressure member seals off the fluid outlet and an open position wherein the back pressure member is displaced from the fluid outlet to permit fluid to flow through the back pressure chamber from fluid inlet to fluid outlet in response to increased fluid pressure in the back pressure chamber. A gas by-pass orifice is disposed in an upper portion of the back pressure chamber which connects the back pressure chamber to a downstream portion of the fluid outlet. The gas by-pass orifice has a diametrical dimension selected to permit flow of gases through the orifice but to substantially not permit flow of liquids through the orifice. Air or gas entering the back pressure valve is automatically vented from the back pressure chamber as the valve fills with each pump stroke to maintain hydraulic firmness and provide improved more accurate fluid flow.

Abstract: A key update system uses information in an update message from a communications system to generate a new key and perform a bidirectional validation of the new key. After a unit validates the new key, at least a portion of information from the update message is used by the communications system to validate the new key. As a result, the communications system is not required to generate and transmit a separate authentication challenge to validate the new key. For example, a wireless communications system can send an update message with a sequence RANDSSD to the wireless unit. The wireless unit generates a new SSD using at least a portion of the sequence RANDSSD, and the wireless unit uses at least a portion of the new SSD to generate a signature value AUTHBS to validate the new key and thereby the home authentication center that initiated the update of the SSD. After the wireless unit validates the new key by comparing the AUTHBS generated by the wireless unit with an AUTHBS generated by the wireless communications system, the wireless unit uses at least a portion of the sequence RANDSSD and at least a portion of the new SSD to generate the validation value AUTHSSD. The validation value AUTHSSD can be sent to the wireless communications system along with a confirmation signal indicating the wireless unit has validated the new key. The wireless communications system can validate the new SSD by comparing the validation value AUTHSSD received from the wireless unit with a validation value generated in the same fashion by the wireless communications system.

Abstract: An inverse multiplexer device has an input port for receiving a stream of data packets, a plurality of output ports for connection to outgoing physical links, and transmit buffers for preparing outgoing packets. An expansion port can receive packets from the transmit buffers and transfer them through a corresponding expansion port on another like inverse multiplexer to designated output links on the other inverse multiplexer. A  controller outputs the data packets on a group of any of the aid links in accordance with an inverse multiplex protocol. The multiplexers can be thus cascaded to increase the number of output links that can be accommodated.
