Patent CA-2194423-C (CA)
Inventor: RAMACHANDRAN RAMAKRISHNAN
IPC: C07C51/265
Filed: 1997-01-06
Granted: 2000-09-19
Abstract: Terephthalic acid is produced by reacting paraxylene with oxygen in a reactor having several vertical stages, the reaction taking place in the liquid phase using acetic acid as solvent and a cobalt-manganese-bromine complex catalyst. During the reaction, a carbon dioxide-containing gas phase is withdrawn from thevapor space of the reactor. The gas phase is cooled to condense vaporized aceticacid therefrom and carbon dioxide is separated from the gas phase and recycled to the vapor space or to the liquid phase or to both of these. In an alternate embodiment, the gas remaining after condensing acetic acid is subjected to catalytic oxidation to oxidize carbon monoxide and methane, if present, to carbon dioxide, and some or all of the carbon dioxide is recycled to the reactor.

Granted: 2001-12-04
Abstract: A system for extended enterprise planning across a supply chain is provided.  The system includes transactional execution system layers (14, 18) for a demand enterprise (10) and a supply enterprise (12). First and second federated electronic planning interchange layers (16, 20) provide a data specification format and an external communication interface for transactional execution system layers (14, 18).  A supply chain planning engine (22), operable to perform planning for the supply chain, is in communication with a third federated electronic planning interchange layer (24) which provides a data specification format and an external communication interface for the supply chain planning engine (22).  A data access/transfer layer (28) interconnects and allows transfer of information between the first, second and third electronic federated planning interchange layers (16, 20, 24).  The supply chain planning engine (22), the first transactional execution system (14) and the second transactional execution system (18) can thereby communicate data which the supply chain planning engine (22) can use to provide constraint based extended enterprise planning across the supply chain.

Title: Method of controlling accumulation of sodium sulfate on the checker packing of a regenerator
Inventor: SCOTT WALTER W
IPC: C03B5/237
Filed: 1997-11-18
Granted: 2001-02-06
Abstract: The instant invention provides a method of controlling the accumulation of sodium sulfate in the checker packing of a regenerator of a cross-fired regenerative-type glass melting furnace. Typically, glass batch materials are melted within the furnace by combustion of fuel. This combustion produces exhaust gas that is drawn through the regenerator and heats the checker packing. During the melting operation; sodium sulfate gas is formed by the melted glass and is carried with the exhaust gas through the regenerator. The sodium sulfate gas may condense on a portion of the checker packing. As the sodium sulfate condensate accumulates on the checker packing, it may restrict the flow of exhaust gas and/or combustion air through the regenerator. In the instant invention, a section of the regenerator which includes the portion of the checker packing with the condensed sodium sulfate is selectively heated to a temperature sufficient to melt the sodium sulfate, while any additional heating of remaining sections of the regenerator is minimized.     In one embodiment of the invention, fuel is injected into a portion of the exhaust gas that passes through the section of the regenerator where the sodium sulfate condensate has accumulated. The fuel burns with the portion of the exhaust gas and heats the portion of the checker packing with the sodium sulfate build-up to melt the sodium sulfate.

Title: An optical spray paint optimization system and method
Inventor: BAUER RICKY JAY
IPC: B05B15/68
Filed: 1996-07-19
Granted: 2006-09-12
Abstract: An optical spray paint optimization system can be removably mounted to a spray paint gun, thus enhancing the ability of the user to guide the direction of the spray and also locate the nozzle at an optimum spray distance from the surface being painted. The preferred apparatus uses a diode laser, a beam splitter and a reflecting mirror to generate a reference beam and a gauge beam. The reference beam propagates in a fixed forward direction, but the direction of the gauge beam is adjustable by adjusting the attitude of the reflecting mirror. The reference beam and the gauge beam intersect at a convergence point which can be repositioned to a selected distance from the nozzle of the spray painting system by adjusting the path of the gauge beam, thus allowing the user to spray at the optimum spray distance by locating the convergence point on the surface being painted. The beams also aid in aiming the spray.

Abstract: This invention provides an improved process for surface modification of polymers and carbon-based materials, and improved materials produced by the process. The preferred surface modification process of the present invention  comprises three steps: a first activation step wherein reactive hydrogen groups are formed in a surface layer of a polymeric or carbon-based material ; a second silylation step wherein the reactive hydrogen groups are reacted wi th a silylating agent to form silicon-containing groups; and a third stabilization step wherein an upper portion of the activated, silylated laye r is oxidatively converted to a silicon dioxide enriched surface layer. The process can be performed using materials not having pre-existing reactive hydrogen groups or precursor groups. Surface modified materials according to  the present invention have improved properties, such as erosion resistance a nd oxygen and water barrier properties, and are potentially useful in numerous industries, such as aerospace and packaging.

Abstract: A quality calculator for Viterbi-decoded data, using zero-state metrics, is provided.  The quality calculator for the Viterbi-decoded data includes: a Viterbi decoder which outputs zero-state metrics of input demodulated data, according to four possible transmission rates of FULL, HALF, QUARTER and 1/8; a register which stores respective zero-state metrics output from the Viterbi decoder; and a quality evaluation unit which reads the zero-state metrics stored in the register, to evaluate the Viterbi-decoded data based on the zero-state metrics, and which determines the actual transmission rate to be the one among the possible transmission rates which has the least zero-state metrics.   Therefore, the zero-state metrics of the demodulated data input to the Viterbi decoder are used as a quality evaluation parameter, so that the quality evaluation can be correctly achieved to avoid errors in the determination of the transmission rate, compared to a quality calculator using a bit error ratio as the quality evaluation parameter.

Abstract: Un appareil d'imagerie radiologique reçoit un faisceau de rayons X portant une image (12) sur un écran plat au silicium amorphe (20), doté d'une unité de détection de lumière (40) placée derrière celui-ci. Ledit écran est une structure multicouche comprenant une couche arrêtant la lumière (26) qui est opaque à la lumière visible mais qui laisse passer les rayons X, une couche de conversion en matière phosphorescente (28) pour transformer les rayons X arrivant sur celle-ci en lumière visible, et un groupement bidimensionnel d'éléments photosensibles (30) en matière semi-conductrice amorphe tel que le silicium amorphe, conçu pour subir un changement détectable de caractéristiques électriques en réaction à l'incidence de la lumière. L'unité de détection de lumière (40) peut être un détecteur de lumière simple conçu pour recevoir la lumière émise par la couche de conversion, passant à travers des zones situées entre les paires voisines du groupement d'éléments photosensibles (30). Etant donné que l'énergie lumineuse ainsi détectée est directement proportionnelle à l'énergie lumineuse totale émise par la couche de conversion, le signal de sortie provenant dudit détecteur de lumière peut être utilisé de manière appropriée pour la commande de l'exposition de l'écran.
