Patent CA-2323756-A1 (CA)
Title: Genetic engineering salt tolerance in crop plants
Inventor: AHARON GILAD
IPC: C12N15/29
Filed: 1999-03-18
Abstract: The invention is isolated nucleic acid molecules encoding Na+/H+ exchanger polypeptides for extrusion of monovalent cations (preferably lithium ions and potassium ions, most preferably sodium ions) from the cytosol of cells to provide the cell with increased salt tolerance. In a preferred embodiment, the nucleic acid is obtained from Arabidopsis thaliana. Crop species transformed with the nucleic acid molecule are capable of surviving in soil with high salt levels that would normally inhibit growth of the crop species.

Abstract: L'invention permet de fournir un accès et une allocation de ressources radio flexibles dans un système universel de télécommunications mobiles (UMTS). En réponse à une demande de service de liaison d'accès radio, le réseau (UTRAN) d'accès de Terre du système UMTS attribue de manière flexible et efficace les ressources nécessaires à l'établissement d'une communication avec un émetteur-récepteur mobile. Le réseau UTRAN comprend plusieurs stations de base permettant de communiquer avec les émetteurs-récepteurs mobiles via une interface hertzienne utilisant les ressources de voies radioélectriques attribuées par un contrôleur de réseau radioélectrique connecté aux stations de base. Des noeuds de service de réseau externes en interface avec les réseaux externes communiquent avec le réseau UTRAN à travers une interface hertzienne d'accès au réseau. Le réseau UTRAN fournit un service de liaison d'accès aux noeuds de service de réseau externes et les liaisons d'accès sont affectées de manière dynamique aux ressources de voies de radiocommunication par le réseau UTRAN. Lors de la mise en place de chaque liaison, le réseau UTRAN relie ou attribue la connexion d'accès à des ressources physiques de transport en utilisant les ressources du réseau UTRAN et les voies radioélectriques de l'interface hertzienne. Dans une version, par exemple, le transport entre les noeuds et le réseau UTRAN comprend une connexion MTA, et une voie radioélectrique de l'interface hertzienne comprend un ou plusieurs codes d'étalement AMCR. L'établissement des correspondances est fondée sur un ou plusieurs paramètres comprenant par exemple un ou plusieurs paramètres de qualité de service et/ou les conditions de trafic courantes. En outre si l'un des paramètres change pendant la durée de vie de la connexion, la connexion peut être commutée vers un type de voie mieux approprié.

Abstract: An optical transmission line which can restrict both wavelength distortion due to a non-linear phenomenon and wavelength distortion due to dispersion, and which is formed by series-connecting a first optical fiber (8) having a dispersion value of 6 to 14 ps/nm/km in a set wavelength band in a wavelength band of 1.5 µm and a second optical fiber (9) having a dispersion value of -14 to -6 ps/nm/km in the above set wavelength band, the dispersion slopes of the first optical fiber (8) and the second optical fiber (9) having signs opposite to each other. Light transmitted from an optical transmitter (11) is shone on the first optical fiber, and light transmitted through the first optical fiber (8) is shone on the second optical fiber (9). Absolute value of dispersion in a wavelength band of 1.5 µm of each optical fiber (8), (9) is set to be at least 6 ps/nm/km to restrict four-light-wave mixing, and the above each absolute value is set to be up to 14 ps/nm/km to restrict local dispersion, to thereby render almost zeroes dispersion values and dispersion slopes in the above set wavelength band over the entire optical transmission line.

Title: Flat bottom tool
Inventor: STOKEY WILLIAM H
IPC: B23B51/00
Filed: 1999-08-20
Abstract: The present invention is a drilling system for cutting flat bottomed holes in work pieces. The tool has two opposing angled cutting edges (62, 64) extending upwardly to create an overlapping web (70) at the center. The angle at which the inner portion of the cutting edge (62, 64) is inclined is increased to create a center point on the cutting surface of the tool.

Title: Machine tool distributor for cryogenic cooling of cutting tools on a turret plate
Inventor: HARRIOTT GEORGE MATTHEW
IPC: B23Q11/12
Filed: 2001-11-07
Abstract: A cryogenic fluid distributor for turret machine tools (e.g.,lathes) directs a stream of cryogenic fluid from an external, pressurized cryogen source to a working position of a machine tool to prevent overheating of the tool. Designed for easy retrofitting and synchronizing with multi-tool turret machines, the distributor allows for a "dual-fluid" machining capability combining a cryogenic fluid and a conventional cutting fluid (flowing via a conventional coolant system built into a given machine tool). Made of low thermal-mass, insulating polymer and metallic parts, the distributor utilizes the different thermal contraction coefficients of the parts to establish cryogenic sealing connections, which eliminates undesired turret plate cooling and assures rapid cryogen flow start-up.
