Title: System and method for establishing dynamic high usage trunk groups
Inventor: SYLVAIN DANY
IPC: H04L12/24
Filed: 1999-10-05
Abstract: The present invention relates to a system and method for provisioning dynamic high usage trunk groups between end offices in a switched telephone network. The system includes a transit trunk subnetwork with ATM facilities connected between the end offices. A call manager communicates with the end offices and the ATM facilities to process signal messages from the end offices, and send corresponding messages to interfaces between the end offices and ATM facilities. The interfaces are configured to dynamically set up and release switched virtual circuits in response to signal messages from the end offices or the call manager. In an alternate embodiment of the invention, an element manager in the end offices is configured to receive signal messages from the call manager to dynamically provision high usage trunks between the end offices.

Title: Proteine anti-oxydante 2, gene et procedes d'utilisation correspondants
Inventor: BEIER DAVID R
IPC: C12P21/08
Filed: 1998-04-01
Abstract: Cette invention se rapporte à l'identification d'un nouveau gène et d'une nouvelle protéine, appelés protéine anti-oxydante 2 (Aop2 et AOP2, respectivement). Des études ont montré que Ltw4 et Aop2 sont un seul et même gène. En outre, l'Aop2 apparaît également comme étant le gène responsable du trait Ath1 chez les souris, une prédisposition à l'athérosclérose. L'homologue humain de ce gène a également été identifié. Cette découverte rend possible une grande variété d'utilisations de l'AOP2 et du gène correspondant, par exemple la mise au point de réactifs (anticorps, vecteurs d'expression, lignées cellulaires, souris co-isogéniques et transgéniques) qui peuvent servir dans le diagnostic et le traitement de l'athérosclérose et des états pathologiques apparentés.

Title: N-methyl-d-aspartate (nmda) receptor blockers for the prevention of atherosclerosis
Inventor: GADSON PRESTON F
IPC: A61K31/19
Filed: 1997-07-31
Abstract: The present invention relates to the novel finding that homocysteine affects the initiation and/or progress of atherosclerosis via a receptor-mediated growth factor effect on vascular smooth muscle cells. This growth factor effect can be inhibited by N-methyl-D-aspartate antagonists via a unique receptor that is in the NMDA receptor family. Through the use of cloning and other procedures, this homocysteine receptor can be characterized in order to develop novel pharmacologic strategies that address the receptor for the prevention and treatment of atherosclerosis.

Title: Integrated, tank/heap biooxidation process for the lixiviation of sulfide ores
Inventor: BATTY JOHN D
IPC: C22B3/18
Filed: 1998-05-18
Abstract: A metal-containing refractory sulfide ore (12) is split into a first portion (16) and a second portion (18). The first portion (16) is partially biodigested by a sulfide-digesting microorganism in a biooxidation reactor (20) where the microorganism is acclimated to the sulfide "diet" provided by the ore. The partially digested ore (22) is then combined (24) with the second portion (18). The resulting material (26) is then dewatered (25, 28), biooxidized (32), and subjected to a lixiviation process (42).

Title: Slanted well enhanced extraction process for the recovery of heavy oil and bitumen using heat and solvent
Inventor: THIMM LAURA
IPC: E21B17/18
Filed: 2000-04-10
Abstract: A technique for the in-situ recovery of petroleum hydrocarbons from an underground formation uses a combination of heat and vaporized solvents comprising lighter hydrocarbons. Liquid solvent is injected through a substantially slanted well, placed near the base of the reservoir, and is vaporized in-situ by applying heat through an indirect heating system placed inside the slanted well. Hot solvent vapor  rises inside the reservoir, contacts the cold viscous hydrocarbons, condenses, dissolves and diffuses into the hydrocarbon in the reservoir. As a result, the viscous hydrocarbon is diluted to a lower viscosity fluid, which drains to the slanted well and is thereafter produced to the surface.

Inventor: FOX THOMAS RUSSELL
IPC: A01D41/14
Filed: 2000-04-27
Abstract: A crop harvesting header includes a frame having a main transverse beam and a plurality of support arms arranged at spaced positions across the width of the beam for supporting the table and a flexible cutter bar. The support arms include two outer rigid support arms arranged at outer ends of the beam for maintaining the ends of the cutter bar rigid and parallel to the beam. In addition, the support arms include four inner flexible support arms spaced between the outer support arms for supporting an intermediate portion of the cutter bar to allow flexible movement upwardly and downwardly of the cutter bar such that a center portion of the cutter bar between the ends of the cutter bar is free to move upwardly and downwardly in response to forces thereon. The flexible support arms float on a counterbalance arrangement. The header frame is floated to allow independent upward and downward movement of the ends which co-operates with a limited flexing of the cutter bar only over a distance of the order of four inches total movement to keep the cutter bar close to the ground. The reel is mounted on two outer arms and a center arm where the center arm is allowed to float in response to cutter bar movement to keep the fingers close to the knife.

Title: Telecommunications network having shared protect capacity architecture
Inventor: ELAHMADI SIRAJ NOUR
IPC: H04B10/213
Filed: 1998-11-05
Abstract: An optical communications network configured in a shared protect capacity architecture. The network includes a plurality of shared and unshared nodes; a plurality of working lines connecting the plurality of nodes to form a ring that shares two or more nodes with another ring; a shared protect fiber optic line connecting the two shared nodes; and a plurality of protect lines connecting the plurality of unshared nodes which are connected by the plurality of working lines. By optically coupling a first Add-Drop Multiplexes of a first shared node to a first port of an optical cross connect using a first connecting path;  optically coupling a second Add-Drop Multiplexer of the first shared node to a second port of the optical cross connect using a second connecting path; and optically coupling a third port of the Optical Cross Connect to a second shared node through a shared protect path, both rings may use the shared protect path to re-route traffic therethrough in the event that one of the rings has a break which severs the working and protect lines which couple two of the nodes thereof. The reduction in the quantity of protect lines, hence the fiber, and the equipment resulting in the associated cost savings are transparent to bit or baud rate, type of optical fiber, and signal format.

Abstract: A wave-powered prime mover comprises a pair of pontoons (2, 3) connected to a central inertial barge (1), each pontoon (2, 3) being pivotally movable by ocean swell or waves relative to the barge (1). A pump (10) connected between each pontoon (2, 3) and the barge (1) converts the motion of the pontoon (2, 3) into water pressure energy. An improved power take-off and damping mechanism is provided for transforming incoming power, oscillating at a low frequency, into a higher frequency oscillating form for use in a generator, turbine, reverse osmosis plant or the like. A hydraulic circuit (10, 32, 34, 35, 37, 39) is used to rectify the incoming power into a uni-directional form for delivery as a continuous flow of pressurised water for doing work such as that described above.

Title: Heat generator for vehicle
Inventor: SUZUKI SHIGERU
IPC: B60H1/08
Filed: 2000-01-20
Abstract: In a heat generator for a vehicle according to the present invention, an operation chamber defined in the heat generator is composed of a heat generation area (7) which receives therein a rotor, a storage area (8) which contains viscous fluid, and a boundary opening (9) of a relatively large surface area, which connects the two areas. The boundary opening is provided with a pair of transfer openings (35A, 35B) in a point-symmetric arrangement with respect to the rotation axis C of the rotor. Guide portions (41A, 41B), each corresponding to each of the openings, are provided in the storage area.   With this structure, since at least one of the transfer openings and the guide portion corresponding thereto are located below the surface level L of the viscous fluid regardless of the attachment angle of the heat generator, the exchange and circulation of the viscous fluid can be carried out between the heat generation area and the storage area, in accordance with the rotation of the rotor.
