Patent CA-2195437-C (CA)
Inventor: HOLLYWOOD STEVEN
IPC: H04Q3/00

Granted: 1999-07-27
Abstract: Noeud de services fournissant un service à valeur ajoutée partagé à l'intérieur d'un réseau téléphonique p. ex. du type réseau publique commuté. Des périphériques (21, 22, 23) tels que des plates-formes d'applications vocales, d'annonces communes ou d'enregistrement de messages sont reliés à un commutateur (25) placé sous le contrôle d'un ordinateur de commande central (24). Le commutateur comporte des processeurs répartis (38, 52) répondant à des signaux provenant de l'extérieur, p. ex. du type multifréquence en code (DTMF) produits pendant que les appels sont en cours de traitement. Les processeurs répartis fournissent à l'ordinateur de commande central des informations tirées desdits signaux. Il n'est donc plus nécessaire que l'ordinateur central analyse les appels en cours pour y détecter la présence de signaux DTMF, cette détection ayant lieu localement et les informations n'étant renvoyées vers l'ordinateur central que si une information pertinente a été détectée. On peut ainsi augmenter la taille du commutateur par rapport à celle de l'ordinateur de commande tandis que la largeur de bande requise pour les transmissions entre l'ordinateur central et le commutateur peut être sensiblement réduite.

Title: Method and apparatus for burning combustible gases
Inventor: MELNYK ALLAN
IPC: F23D14/68
Filed: 1997-02-07
Granted: 2000-01-18
Abstract: A method and an apparatus for burning combustible gases contained in a mixture comprised of the combustible gases and a liquid. The apparatus comprises: a separator, having an upper end and a lower end. A first portion of the gases is directed out of the upper end and the liquid and a second portion of the gases are directed out of the lower end; an inlet; and a burner which communicates with the upper end suchthat the first portion contacts the burner for combustion and the combustion creates a vacuum effect which produces an air current outside of the separator from the lower end to the burner. The lower end communicates with the air current such that thesecond portion is drawn by the air current to the burner. The method comprises the steps of: directing the mixture into the separator and deflecting the liquid out of the lower end; directing the first portion along a first current path towards the upper end and to the burner; burning the first portion in order to produce a second current path; directing the second portion along the second current path to the burner; and burning the second portion.

Abstract: A metallic pipe may be used as a burning bar if the pipe contains wires. The wires are usually steel but may be combinations of steel wires, aluminum wires, magnesium wires and the like. To use the burning bar one end is heated to at least red hot condition. Oxygen is then pumped down the pipe and the pipe then produces a self-sustaining high temperature, high heat flame. A burning bar may be used for demolition and similar uses. In this improved burning bar, the wires within the pipe are arranged so that the wires do not extend the full length of the pipe.     There is a portion of the pipe adjacent to the end of the pipe held by the operator which does not contain any wires. The pipe is thus self extinguishing at the point where the wires cease thereby providing safety to the operator and economic advantages.

Abstract: A plurality of time-division multiplexed data streams which are merged into a single data stream containing a plurality of data words and which are characterized by state vectors, are concurrently processed.      The state vectors are stored in a read-write memory having a plurality of addressable memory locations. During an initial clock cycle, a pipeline receives an input data word from one of the data streams, an input state vector characterizing that data stream, and the memory location address of the input state vector. During one or more intermediate clock cycles, the pipeline processes the input data word and the input state vector to yield an output data word and an output state vector. During a final clock cycle, the pipeline transfers the output data word to an outgoing data stream, and transfers the output state vector into the aforementioned memory location address. A controller coupled to the memory and to the pipeline synchronizes operation thereof. A null cycle generator coupled to the pipeline and to the controller inserts null cycles into the concurrently processed data streams at regular time intervals and outputs a NULL signal to the controller during each null cycle. A multiplexer coupled between the controller and the memory multiplexes access to the memory between the controller/pipeline, and an alternate controller.     Read access to the memory by the controller or pipeline is inhibited while the NULL signal is output, and write access to the memory by the pipeline is inhibited while an OUTGOING NULL replica of the NULL signal is being output by the pipeline during the final clock cycle.      Accordingly, the alternate controller may gain read access to the memory while the NULL signal is output, and may gain write access to the memory while the OUTGOING NULL signal is output.

Abstract: A composite electrode in which two solid interpenetrating electrolytes are used, a first electrode of an organic nature, ideally made of a dry or gelled polymer made conductive by the dissolution of a salt or a mixture of salts ideally containing lithium ion, and which acts as a deformable binder for the composite, and a second electrolyte of a mineral nature, ideally vitreous, a specific conductor of ions, particularly of lithium and in which the components of the first polymer electrolyte are insoluble. The solid mineral electrolyte is employed as an aqueous solution or a mixture of water and light alcohols, which is put into contact with the materials of the electrode in dispersed form in order to wet at least part of the solid phases of the composite, namely the grains of the active material of the electrode, the electronic conduction additive as well as the voltage collector of the electrode on which the dispersion is applied so as to first form a porous mineral sub-set. The organic electrolyte ideally contains a polymer which is then introduced by permeation (impregnation) in the mineral porous sub-network so as to make up the composite electrode of the invention.
