Patent CA-2145084-C (CA)
Title: Method and regenerator for regenerative heat transfer
Inventor: RUOTTU SEPPO
IPC: B01J8/26
Filed: 1993-09-24
Granted: 2005-04-05
Abstract: The invention concerns a method and a regenerator for transferring heat from one flow to another. The method is based on recirculating a granular heat transfer material between the circulating fluidized bed reactors of the regenerator configuration (comprising only two circulating fluidized bed reactors (A) and (B) in the basic configuration), whereby a tendency toward temperature equalization of the flows participating in the heat transfer process by entering the different circulating fluidized bed reactors is attained.   The equalization of the temperatures is controlled by adjusting the particle flows between the reactors. The mixing of the flows is prevented by directing the particles separated in cyclone chamber (5) of circulating fluidized bed reactor (A) primarily into channel (10), where the particles form a fixed bed layer. From the bottom part of the channel section (10), a particle flow of desired volume rate is controlled to move from circulating fluidized bed reactor (A) to the other circulating fluidized bed reactor (B). When the channel section (10) becomes full, the remaining portion of the particles separated in the cyclone (5) fall back into the circulating fluidized bed reactor (A). The situation and operation of reactor (B) is fully analogous.

Title: Apparatus for providing audible instructions or status information for use in a digital television system
Inventor: HAILEY JAMES EDWIN SR
IPC: H04H20/00
Filed: 1995-05-18
Granted: 1999-04-27
Abstract: A digital television system receives transmitted television information in the form of a stream digital packets representing video and audio information in compressed form. A packet transport unit routes the digital packets to respective digital video and audio signal processing sections according to header information contained in the packets. The digital processing sections decode and decompress the respective packets to form sequences of digital words which are subsequently converted to analog form. Apparatus for providing audible messages, such as operating instructions and status information, in tone or voice form includes a memory for storing digital representations of the audible messages in the same compressed form which the transmitted audio packets have, and a controller for selectively directing the digital representations to the packet transport unit when it is desired to provide the audible messages. The digital representations of the audible messages are automatically routed by the transport unit to the digital audio signal processing section which will decode and decompress the digital representation of the audible messages in the same manner as it does the transmitted audio packets. As a result, analog versions of the audible messages will be produced.

Abstract: Débitmètre massique à effet de Coriolis possédant une plaquette d'entretoisement à souplesse améliorée et assurant une réduction de la concentration de contraintes dans la plaquette d'entretoisement ainsi que dans les tubes d'écoulement du débitmètre et les zones de ceux-ci qui se situent à proximité de la plaquette d'entretoisement. On a mis au point une plaquette d'entretoisement présentant un vide dans la zone comprise entre les trous traversés par les tubes d'écoulement. Ce vide augmente la souplesse de la plaquette et éloigne des joints brasés entre la plaquette et les tubes la concentration de contraintes dues à l'exploitation et à la fabrication. Les contraintes sont réduites et déplacées depuis les tubes d'écoulement vers une zone située à l'intérieur de la plaquette d'entretoisement, cette zone étant moins importante quant à la vie utile et la fiabilité globale des tubes d'écoulement. Le débitmètre est plus sensible puisque ladite plaquette d'entretoisement répond plus souplement aux mouvements dus à l'effet de Coriolis. On a également prévu d'autres modes de réalisation assurant une plus grande souplesse de la plaquette d'entretoisement sans atténuer la rigidité dont elle a besoin pour s'opposer à tout mouvement indépendant indésirable des tubes d'écoulement.
