Patent CA-2232634-A1 (CA)
Inventor: BRAITHWAITE STEPHEN JOHN
IPC: H04L27/22
Filed: 1996-09-27
Abstract: Une pluralité de stations émettrices et réceptrices sont placées en des lieux répartis au hasard au sein d'un réseau de télécommunications, et un circuit de commutation est placé au sein des stations elles-mêmes de manière à acheminer les appels entre les stations du réseau à l'aide d'autres stations du réseau destinées à relayer les appels si nécessaire. A cette fin, chaque station (20) comporte une unité de commande d'acheminement d'appels qui agit de manière à choisir une autre station (21) à laquelle sera transmis un appel d'une source S vers une destination D et qui est destinée à relayer l'appel. L'unité de commande d'acheminement d'appels émet un signal d'interrogation destiné à être reçu par d'autres stations du réseau situées dans la zone couverte par la station émettrice (20) et l'unité de commande d'acheminement d'appels de chacune des autres stations (21) émet un signal d'accusé de réception lorsque la station (21) est disponible pour relayer un appel en réponse au signal d'interrogation reçu de la station (20), le signal d'accusé de réception étant émis après un délai qui indique la disponibilité de la station (21) à relayer l'appel vers sa destination prévue. L'unité de commande d'acheminement d'appels de la station (20) choisit ensuite une station (21) destinée à relayer l'appel sur la base de la réception d'un signal d'accusé de réception provenant de ladite station dans le délai le plus rapide.

Title: Arrangement for ensuring uninterrupted current supply to an electrical consumer
Inventor: KOHLSTRUCK BERND
IPC: H01M8/0438
Filed: 1996-10-07
Abstract: An arrangement is disclosed for ensuring an uninterrupted current supply to at least one electrical consumer which draws energy from an alternating voltage network and is supplied with energy in the event of a network failure by a fuel cell. The fuel cell (8) is connected at its electrical outputs to at least one current inverter (7) whose output is connected to the minimum of one alternating voltage consumer (1, 2) and to a branch containing a switch (4) on the consumer side of the switch; the switch is connected to an alternating voltage network (6) and is opened in the event of the voltage in the alternating voltage network falling below a predetermined level and closed if the alternating voltage is above that threshold; and the fuel cell operates in stand-by mode if the network voltage is above the threshold, and, if the voltage is below the threshold, in a mode in which the energy required by the consumer is supplied via the current inverter (7).

Abstract: Curable coating compositions comprising either a liquid or particulate curable film-forming resinous material, a flow control agent which is a copolymer and optionally a carrier for the liquid resinous material. The copolymer is from at least one non-amino, non-hydroxyl and non-acid functional alkyl acrylate or methacrylate containing from 1 to 20 carbon atoms in the alkyl group, and functional monomer of either (i) amino functional acrylates and methacrylates in an effective amount to give the copolymer an amine value in the range from 2 to 25, or (ii) acid functional acrylate and methacrylate in an effective amount to give the copolymer an acid value in the range of from 10 to 30.  Additionally, with either functional monomer (i) or (ii) another functional comonomer (iii) can be present in the copolymer which is hydroxyalkyl acrylate and/or hydroxyalkyl methacrylate and/or caprolactone polyol monomer. Comonomer (iii) can be present in the copolymer in an effective amount to give the copolymer a hydroxyl number which is in the range of about 0 to 100. The copolymer flow modifiers enhance the rheology of the curable film-forming resinous material like thermosetting powder coating compositions to provide for smoother coatings while at the same time not adversely affecting appearance or adhesion with associated coatings, for example, basecoats when the coating composition is a clearcoat.

Title: A method and system for communication access restriction
Inventor: HAMDY-SWINK KATHRYN ANNE
IPC: G06F21/31
Filed: 1997-06-18
Abstract: A network-based telecommunications system and method that restricts the dial-in access to a resource of a subscriber to only a communication from an authorized user of the source. A switch receives a communication directed to a subscriber from a calling party. Prior to connecting the communication to the terminating equipment associated with the subscriber, the switch requests processing information. An authentication unit determines whether the calling party is an authorized user by checking whether a passcode provided by the calling party corresponds to a passcode being held by the authentication unit.  If the passcode corresponds, then the authentication unit identifies the calling party as an authorized user, and the communication then may be connected to the terminating equipment of the subscriber. If the passcode fails to correspond, then the authentication unit fails to identify the calling party as an authorized user. The communication is not connected to the terminating equipment of the subscriber.
