Patent CA-2300807-A1 (CA)
Inventor: INGLEDEW WILLIAM M
IPC: C12P7/06
Filed: 2000-03-17
Abstract: A process is described for the production of alcohol in which a starch- or sugar-based aqueous fermentation medium is prepared and to this fermentation medium is added urea hydrogen peroxide in an amount sufficient to substantially reduce the level of bacterial contaminants in the fermentation medium. The urea hydrogen peroxide is left in contact with the fermentation medium for a time of at least one hour and sufficient to substantially reduce the level of bacterial contaminants. Thereafter the fermentation medium is inoculated with yeast wherein the yeast produces catalase enzyme which degrades liberated hydrogen peroxide to water and oxygen. This oxygen is needed by the yeast for membrane sterol and unsaturated fatty acid synthesis. Both urea and oxygen are supplied in near optimum amounts for growth subsequent to the suppression of bacterial contaminants by urea hydrogen peroxide. The fermentation continues to produce alcohol, in particular fuel or industrial alcohol, at the highest possible yields.
Patent CA-2301449-A1 (CA)
Inventor: MCMULLIN WILLIAM P
IPC: H04W4/16
Filed: 2000-03-21
Abstract: Methods and apparatus are disclosed for providing automatic redirection of an incoming voice telephone call from a caller to a subscriber proxy when an attempt by the caller to connect to a subscribers mobile/wireless/cellular telephone is blocked due to either having the mobile phone off, on but not answered, or in use. The subscriber has further established communications between a subscriber's data communication terminal (DCT) (e.g. PC, Internet appliance, Palm TM handheld etc.) a computer network (e.g. the Internet). The subscriber proxy is connected to both the PSTN, CMTS and the Internet, and produces audio interaction with the caller.  The subscriber proxy also notifies the subscriber of the incoming call via the subscriber's DCT. The subscriber's DCT can optionally be used by the subscriber to control and interact with the incoming call by communicating with the computer proxy while the subscriber continues to maintain the Internet connection.

Title: Sonde jumelle robotisee pour mesures sur cartes de circuits imprimes et sur ensembles electriques et electroniques
Inventor: COLLINGBOURNE ERIC D
IPC: G01R31/28
Filed: 1998-08-21
Abstract: L'invention concerne un système et un procédé automatisé de test de circuits. L'invention utilise des dispositifs robotisés pour amener, avec une très grande précision, des points de sonde (122, 123) sur des points considérés d'une plaquette (140) de circuit. Selon certains modes de réalisation, l'invention permet la réalisation des tests à distance. L'ensemble robotisé comporte des moteurs (110, 111, 112) et un logiciel de commande associé. Le logiciel de commande peut traiter une entrée utilisateur et commander aux moteurs le positionnement des points de sonde. Ce logiciel commande aussi à la sonde l'exécution des tests, et communique à l'utilisateur les résultats des tests. Trois moteurs assurent le positionnement des points de sonde sous la commande du logiciel. Les moteurs utilisent un système de positionnement à coordonnées polaires. Un moteur rotatif (111) amène un second point de sonde dans une position angulaire définie par rapport au premier point de sonde. Un moteur radial (112) positionne le second point de sonde selon un mouvement radial calé sur le premier point de sonde. Un moteur zénithal (110) positionne les deux points de sonde dans une position zénithale par rapport au circuit et met les deux points de sonde au contact du circuit.

Title: Modular snow melting carpet device
Inventor: ABUKASM ZIAD GEORGES
IPC: H05B3/06
Filed: 2000-03-15
Abstract: This modular snow melting carpet device for melting snow and ice on pathways comprises a flat sheet of generally rectangular shape, two conducting wires embedded in the sheet and running along the length of the sheet and generally close to their respective length edge. The conducting wires are connected at both of their extremities to a female single pin connector also embedded into the sheet and exposed at the width edges. The device also comprises a plurality of heating elements also embedded into the sheet and parallel connected along said conducting wires and, two male single pin connectors adapted to mate with the female connectors of one edge and connected to a power source. Additionally, an intersection device may comprise two crossover connecting wires embedded into the sheet and electrically insulated from the conducting wires and heating elements. Both extremities of each crossover wires are connected to an additional female single pin connector exposed at both length edges of the sheet and in close proximity to its respective width edge. Two of these additional connectors, close to a same width edge, are electrically connected to their respective closest connector. The crossover wires allow for interconnecting another device to any of the four edges of the modular device. All female connectors are maintained covered by removable insulating plugs that can be replaced by double male couplers to parallel connect two adjacent heating devices. All distances between each female connector and its respective closest sheet corner are equal to each other, in order to allow for electrical connection between two adjacent modular carpet devices.
Patent CA-2303215-A1 (CA)
Inventor: ALLEN JAMES F
IPC: H04Q11/04
Filed: 1998-09-09
Abstract: A telecommunications switch includes a plurality of digital signal processing modules resident on a communications services card, wherein each module includes its own time slot interchange (TSI). Significantly, this allows each digital signal processing module to simultaneously receive all information transmitted from the line cards. In addition, since each digital signal processing module includes its own dedicated TSI and each of these TSIs is connected in parallel to the same TDM bus, one or more TSIs may simultaneously output data onto the TDM bus during a time slot. Adavantageously, this allows multiple TSIs to be assigned to the same transmit time slot and mux transmit time slots at the bit level. For example, if a first TSI on the digital signal processing module needs only three bits of an eight bit time slot, and a second TSI needs five of less bits, then both TSIs can be assigned to transmit during the same time slot. The first TSI would output data on, for example, the three least significant bits, while the second TSI would output its data onto the remaining bits of the time slot.

Title: Folding hay rake
Inventor: NADEAU PAUL
IPC: A01D78/00
Filed: 2000-07-04
Abstract: An agricultural implement such as a folding rake has a main frame and two secondary frames pivotally mounted on opposite sides of the main frame for pivotal movement between a transport position extending along respective sides of the main frame and a field position diverging from the respective sides of the main frame. A folding mechanism for moving the secondary frames between their transport and field positions includes two fold arms pivotally mounted on the main frame and two connection braces pivotally connected to the respective secondary frames and the fold arms. The fold mechanism includes a fold actuator for pivoting the fold arms about the fixed pivot to move the secondary frames between the transport and the field positions. The preferred fold actuator includes a slide mounted on the main frame of the implement, links connecting the slide to the fold arms and an hydraulic cylinder mounted on the main frame for moving the slide along the main frame.  The arms isolate the fold actuator from forces acting on the secondary frame, mitigating the potential for cylinder creep. The implement can be used with only one of the secondary frames deployed by disconnecting one of the links from the slide.

Title: Fatty acid synthase mrna binding protein
Inventor: SEMENKOVICH CLAY
IPC: A61K48/00
Filed: 1998-12-21
Abstract: Disclosed is a 178 kDa glucose-inducible human fatty acid synthase (FAS) mRNA  binding protein which has been purified to homogeneity and its binding element characterized. This large phosphoprotein binds to a novel repetitive element in the 3' untranslated region (UTR) of the FAS mRNA. In particular, the binding has been mapped to a 37 nucleotide stretch within the first 65 bases of the 3' UTR of mRNA. The binding protein is useful for mediating FAS  expression, for regulating lipoprotein secretion and cell growth and for screening of test compounds for activity as inhibitors of FAS.
