Title: Procede et dispositif de production de gaz de combustion, de gaz de synthese et de gaz de reduction a partir de combustibles solides
Inventor: WOLF BODO
IPC: C10J3/46
Filed: 1998-10-06
Granted: 2008-12-16
Abstract: L'invention concerne un procédé et un dispositif permettant de produire des gaz de combustion, de synthèse et de réduction à partir de combustibles fossiles renouvelables, d'autres biomasses, d'ordures ou de boues, ces derniers étant largement séparés, avant leur introduction dans le réacteur, en produits gazeux et en solides, p.ex. en gaz dégagé de distillation lente et en charbon de bois, puis cédés séparément au réacteur. Selon l'invention, le réacteur comprend un brûleur mixte, une chambre de combustion, un gazéificateur de flux de particules, un canal de compensation de température et un bain d'eau. Le brûleur mixte dispose de dispositifs permettant la combustion substoechiométrique des produits gazeux dégagés de distillation lente et de dispositifs de rotation qui lancent par centrifugation les particules fluides sur la paroi de la chambre de combustion. Les gouttelettes de scories fluides tombent dans un bain d'eau. La poussière combustible peut réagir par endothermie avec l'agent de gazéification provenant de la chambre de combustion pour produire un gaz de gazéification. Le coke résiduel est amené à tourbillonner de telle façon qu'il ramène la température de la paroi de la chambre de combustion en-deçà de la température de fusion des scories par absorption thermique par convection. Il se forme alors une couche de protection de scories solidifiées sur la paroi interne de la chambre de combustion.

Abstract: The code division multiplex transmission system according to the present invention produces data for transmission by, time-division multiplexing the signals for synchronizing spread code prepared for an easy synchronization of spread code on the receiving side and the information related to the structure or synchronization of each of a plurality of transmission data streams such as parameters information about the coding rate of the convolution code and interleaving size for each transmission data stream, generating spread frequency modulated signals of the above time- division multiplexed signals by a spread frequency modulation using a spread code known to the receiving side, and code-division multiplexing the resulting spread frequency modulated signals over the spread frequency modulated signals of the plurality of transmission data streams. As a result, the receiving terminal can obtain information such as parameters information of all the transmission data streams, as long as the receiving terminal receives the synchronization signal. Therefore, even if the receiving terminal does not understand the parameter values required for the reception of each transmission data stream, the receiving terminal can receive any transmission data stream easily and quickly, by setting the parameter values for each receiving process based on the parameters information about each transmission data stream obtained by the reception of the synchronization signal.

Patent CA-2335001-C (CA)
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Granted: 2007-07-17
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder.  A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

Abstract: The invention relates to a method and a device for cutting to length strips (1) or sheets in the rolling or transport line (x-x), notably on a rolling table (2), using shears (3) having one blade holder (4, 4') each arranged above and below the strip (1), which blade holders are guided by means of fixing elements (5, 5';6, 6'). The invention is characterized in that the shears (3) with the blade holders (4, 4') and their fixing elements (5, 5';6, 6') are displaced sideward out of the rolling line (x-x) into a neutral parking position after each cut when a strip (1) or sheet is located in the rolling or transport line. Before displacement of the shears (3) the frontal joint between the blade holders (4, 4') or between the fixing elements (6, 6') overlapping the rolling line (x-x) is opened. For a subsequent cut the shears are moved into the rolling line such that they overlap same in a U-shape. Before the next cut the frontal joint between the blade holders (4, 4') or between the fixing elements (6, 6') overlapping the rolling line (x-x) is closed. Said joint is coupled in a positive and non-positive manner by means of a clamping element (7).

Granted: 2010-10-19
Abstract: This invention provides novel substrate compounds that selectively inhibit the proliferation of pathological cells, for example, pathological cells that endogenously overexpress a target enzyme that confers resistance to biologic and chemotherapeutic agents. The enzyme acts on a substrate compound to 1) convert it to a cellular toxin and/or 2) release a toxic byproduct. In one embodiment, the activity of the target enzyme has been greatly enhanced in a target cell as a result of loss of tumor suppressor function and/or selection resulting from previous exposure to chemotherapy. In another embodiment, the pathological cell contains a target enzyme that is an expression product of an infectious agent in the cell. Further provided by this invention is a method for treating a subject by delivering to the subject a prodrug as described herein. The prodrugs of this invention may be used alone or in combination with other chemotherapeutics or alternative anti-cancer therapies such as radiation.

Abstract: A user-configurable firewall and method in which a user-changeable security setting for a client computer is maintained by an access server through which a user accesses the public network. The user-changeable security setting can be used to specify which outside computers or network devices may access the client computer and what type of access to the client computer is allowed. If an attempt to access the client computer is made, the user-configurable security setting is checked to determine if the attempted access is allowed by the current security setting. If the attempted access is allowed by the current security setting, access is allowed to the client computer; otherwise, access is not allowed. If the user changes the user-configurable security setting, the changes to the user-configurable security settings are provided to the access server.
