Patent CA-2226206-A1 (CA)
Inventor: ISBISTER STANLEY F
IPC: B25B13/48
Filed: 1998-01-06
Abstract: An adapter for use with a drive tool such as a ratchet will enable a user to reach a fastener that is otherwise difficult to reach. The adapter includes a first drive member having a recess in a distal end for connection to the drive tool and, in the proximal end, a centre axial blind bore and a plurality of equally spaced blind bores radially spaced from the centre bore.  A second drive member also has a means for connecting it at the distal end thereof to a socket or to a screwdriver bit. At its proximal end the second drive member has a centre axial blind bore and a plurality of equally spaced blind bores radially spaced from the centre bore. The drive members are connected together by a first bar having equal length cylindrical legs angled relative to each other, with each leg being rotatably received in a corresponding centre bore. A  plurality of second bars, each having equal length cylindrical legs angled relative to each other, span the distance between the drive members, with the legs being slidably and rotatably received within corresponding radial blind bores of the drive members. As one drive member rotates on its axis the second bars cause the other drive member to rotate on its axis so as to impart rotation to the fastener being driven thereby.

Abstract: La présente invention concerne un procédé et un équipement de blanchiment de pâte à papier de densité élevée avec un réactif gazeux. La pâte est déchiquetée puis peluchée, en présence d'un gaz de contact qui comprend le réactif de blanchiment gazeux, dans une cuve amont (52) comprenant un contacteur à pointes et à cloisons, de façon à mettre la pâte en suspension dans le gaz de contact et à faire réagir le réactif de blanchiment avec cette pâte. Elle est retenue dans le contacteur pendant un temps déterminé, qui est suffisant pour consommer environ 75 à 90 % d'une dose choisie du réactif de blanchiment gazeux qui est nécessaire pour délignifier la pâte de densité élevée, en la faisant passer d'un indice Kappa initial à un indice Kappa intermédiaire. La pâte et le gaz de contact sont ensuite envoyés séparément dans un réacteur à lit poreux, où la réaction entre la dose choisie de réactif de blanchiment gazeux et la pâte est sensiblement achevée, afin de poursuivre la délignification de la pâte de densité élevée, qui la fait passer de l'indice Kappa intermédiaire à l'indice Kappa final.

Title: Memory exceed notification for wireless network communication device
Inventor: LAWRENCE CHRISTOPHER GREGORY
IPC: G08B5/22
Filed: 1997-06-09
Abstract: A wireless communication device comprises a memory exceed indicator. The wireless communication device receives a message from a network. Upon receipt of the message, the device determines whether there is sufficient memory to store the message. If there is insufficient memory, the device activates a memory exceed indicator which indicates that a message is being stored in the network and that the memory of the wireless communication device contains insufficient memory to receive and store that message. If one or more messages are deleted from the memory of the device in order to make room for new messages, then a new message received from the network is stored in the memory of the device and the memory exceed indicator is deactivated.

Inventor: EHLE DAVID L
IPC: G01R1/16
Filed: 1996-09-24
Abstract: L'invention concerne une jauge miniature à enroulements en orientation croisée (30), dans laquelle un aimant orienté en matériau appartenant au groupe des terres rares (40) est fixé sur un arbre rotatif (38) pour engendrer un flux magnétique transversal par rapport à l'axe de l'arbre. Le boîtier de la jauge constitué d'une bobine supérieure (32) et d'une bobine inférieure (34), enveloppe l'aimant et supporte l'arbre rotatif. Un premier enroulement (42) et un second enroulement (44) ont placés en orientation croisée autour du boîtier de la jauge et encerclent l'aimant. Un anneau de flux (50) est placé autour de ces deux enroulements (42, 44), dans l'alignement de l'axe de l'aimant (40). Grâce à la puissance suffisante de l'aimant (40) et à la proximité suffisante entre l'anneau de flux (50) et les deux enroulements sus-mentionnés, on obtient une redistribution du flux établi par l'aimant de sorte que le flux magnétique mesuré à la surface des enroulements dépasse sensiblement la densité de flux magnétique mesurée lorsque l'anneau de flux est enlevé. Cette configuration de jauge facilite la fabrication de jauges dont la taille est suffisamment petite pour se prêter à un montage direct sur les cartes de circuits imprimés au moyen du matériel classique utilisé pour le montage des composants électroniques.

Patent CA-2240593-A1 (CA)
Inventor: WILLIAMSON TREVOR
IPC: A23L31/00
Filed: 1996-12-09
Abstract: A human food product comprises a higher ploidy strain of Fungi imperfecti of which each parent has a genetic growth constraint not shared by the other parent. One parent is for example auxotrophic for two compounds selected from histidine, arginine, leucine and adenine and the other for the other two. The nucleic acid content of the strain is preferably less than 2 % by weight. The strain may be made by killing a higher ploidy strain of Fungi imperfecti and simultaneously reducing its nucleic acid content to below 2 % by weight by treatment with water. The process may include preparing a higher ploidy strain of edible Fusarium by culturing two auxotrophs thereof together in a medium containing nutrients permitting both to grow and then culturing organisms derived from such culture in minimal medium. The invention is applicable to the production of human food by culturing the strain in conditions such that reversion or partial reversion to the haploid form(s) is minimised.

Title: Multiple drum mixing system
Inventor: NIEMI WALTER
IPC: E01C19/10
Filed: 1998-07-10
Abstract: A drying and mixing plant is provided comprising a tapered inner drum and an oppositely tapered outer drum attached together concentrically and rotated as a unit. A burner directs a hot air stream into the small end of the inner drum.  Material is fed into the small end of the inner drum, where impellers lift it and drop it into the hot air stream and move the material through the inner drum aided by the downward taper of the inner drum. The material exits the inner drum and enters the outer drum where an additive material is introduced and mixed with the material as both move through the chamber between the inner and outer drums to a material outlet. The receiving end of the outer drum is enclosed in a shroud, therefore the air stream is directed through the chamber between the drums, the chamber having an expanding cross section which slows the air down allowing fines to precipitate out. The device may include nozzles for spraying water across the path of the air stream and material flow, and further may include, for fluid additive materials, additive nozzles spraying the additive material across the path of the air and material. A third drum may be provided inside the inner drum, allowing separate addition of a third material, and further reducing fines in the air. The device is particularly suitable for mixing asphalt paving mix.

Title: Optical node system for a ring architecture and method thereof
Inventor: FRIGO NICHOLAS J
IPC: H04J14/02
Filed: 1998-07-27
Abstract: An optical node system for an optical ring network reduces certain costs associated with current ring architectures by using at least a portion of the light from an incoming optical signal to transmit an outgoing optical signal. In accordance with certain embodiments, the node includes an optical multiplexer which receives optical signals having a plurality of wavelengths. The optical multiplexer can be configured to output optical signals having certain wavelengths and to route at least one optical signal from the ring of at least one particular wavelength (or wavelength band) to a corresponding optical transceiver. The optical transceiver receives the incoming optical signal of the particular wavelength routed from the optical multiplexer and transmits at least a portion of the light from the incoming optical signal having the particular wavelength. The optical transceiver can modulate user information onto the light of the particular wavelength and/or pass at least a portion of the incoming optical signal for transmission as an outgoing optical signal onto the optical ring network. Thus, the optical node system alleviates the need for nodes to have a laser tuned to the particular wavelength for transmitting an outgoing optical signal having the particular wavelength.
