Inventor: DEGEORGE CHARLES WILLIAM
IPC: C10G2/00
Filed: 1999-02-05
Abstract: A gas conversion process including catalytic hydrocarbon synthesis from a synthesis gas comprising a mixture of H2 and CO, produces hydrogen from the synthesis gas and upgrades synthesized hydrocarbones by one or more hydroconversion operations which utilize this hydrogen. The hydroconversion also produces a hydrogen rich tail gas which is used in the process for at least one of (i) hydrocarbon synthesis catalyst rejuvenation, (ii) the hydrocarbon synthesis, and (iii) hydrogen production. In one embodiment the tail gas is used to hydrodesulfurize sulfur-containing hydrocarbon liquids recovered from the natural gas used to form the synthesis gas. The hydrogen production is accomplished by physical separation, such as PSA, with or without chemical means such as a water gas shift reaction.

Abstract: A control system for an inflatable chamber on a patient's aorta monitors (402, 412) an actual flow duration time for inflating or deflating the chamber with a volume of pressurized fluid from reservoirs, and compares (404, 416) the actual time with a target time If the actual inflation time is too short with respect to the target time the pressure is decreased (408), and if too long the pressure is increases (410). Also, if the actual deflating time is too short with respect to the target time, the vacuum is decreased (418), and if too long the vacuum is increased (420). The change in either of the pressure sources is varied (422-428) until the desired value is reached within the reservoirs.

Patent CA-2331728-A1 (CA)
Inventor: SCHNEIDER EDWARD T
IPC: B25B1/06
Filed: 1999-09-07
Abstract: A movable clamping element (56) engages a workpiece, whereby a spring (86) is compressed, limiting the amount of clamping force applied to the workpiece. A retainer nut (88) is selectively moved through the use of the tool to a selectable position along a threaded shaft (80) to adjust the spring compression, hence the clamping force. After initial setup, an electrochemical actuator (110) is actuated to melt a polymer, forcing a piston assembly (118, 120) and a bearing (84) to shift the threaded shaft (80) longitudinally against the spring, moving the clamping elements apart a short distance to release or receive a workpiece. The electrochemical actuator is then deactivated, allowing the spring to expand, clamping the workpiece between the clamping elements with the selected force.

Title: Flexible call routing system
Inventor: SILVA MICHAEL
IPC: H04M3/00
Filed: 1999-06-03
Abstract: The principle object of the present invention, is to provide flexibility in the routing functions performed in the switching system.  Another object is to provide a router (200) that can be centralized in a host computer (24) or distributed among various switching nodes (32b-32f). The router is easily programmable by the system operator to provide different routing algorithms for various calls. The router can be used in a system with a single switching node. However, it is particularly adopted for use in a multiple-switching-node system, either as a central, host resident unit, or as a distributed router resident on the switching nodes. A router embodying the invention uses router tables (201) that are readily configurable by the system operator to route calls based on predefined routing criterion in the incoming or outgoing call.

Abstract: A boar cart (10) for carrying a boar through alleyways of a sow insemination area for interaction with the sows during insemination is formed by a cage for containing the boar including a cage floor (17) on which the boar stands, two sides (50,51) each defined by vertical bars on a respective side of a longitudinal center line of the cage assembly for confining the boar so that the boar is maintained extending longitudinally of the cage, a front (52) and a rear (53) defined by vertical bars, at least one of which can be opened as a door to allow entry and exit.  The cage is mounted on rear driving wheels (22) and front steering/caster wheels (35,36). The cage is defined by a front portion (12) and a rear portion (11) connected together for pivotal articulated movement about one or two pivot couplings defining a vertical pivot axis (13) arranged substantially at the center line such that the cage can articulate to the left and to the right for navigating left and right comers in the alleyways while the boar is retained in the cage. The length of the cage is reduced by bowing the front and rear bars. The front steering wheels (35,36) can be set to direct the steering slightly to the left or right so as to tend to guide the cage along one or other side of the alley where it has rollers (43,44) to run along a rail and hold the boar close to the sows on one side.
Patent CA-2346078-A1 (CA)
Title: Random access in a mobile telecommunications system
Inventor: BEMING PER
IPC: H04L1/18
Filed: 1999-08-17
Abstract: A method for processing multiple random access requests is disclosed in which a base station (204) transmits an acquisition indicator signal (A), which indicates that the base station (204) has detected the presence of a random access transmission (P,M). The acquisition indicator (A) can be generated based (212) on the amount of energy received (210) on the random access channel (e.g., as opposed to the correct/incorrect decoding of a random access message). Consequently, the delay between the beginning of the random access transmission (P,M) and the beginning of the acquisition indicator transmissions (A) is significantly shorter than the delay to the beginning of an acknowledgement transmission based on the reception of a correctly decoded random access message. If a mobile station (202) does not receive a positive acquisition indicator (A), it should interrupt the present transmission and start to retransmit the random access burst in the next time slot, while modifying the transmission power level accordingly between the successive re-transmissions.
Patent CA-2348444-A1 (CA)
Inventor: BAILEY JAMES CHRISTOPHER
IPC: A47L13/20
Filed: 1999-10-29
Abstract: A vent and fluid transfer fitment (10) for sealing and transferring a fluid from an inverted fluid-filled container (16) without premature leakage to a receiver attachment (22), has a transfer check valve (12) and a venting check valve (13) which are preferably duck-bill valves. The transfer check valve is attached to the fitment for allowing fluid to be transferred from the container when the receiver attachment engages the transfer check valve. The venting check valve is also attached to the fitment for allowing air to displace the fluid as the fluid exits the container, wherein both the transfer check valve and the venting check valve have an inherent sealing pressure created by the static pressure of the fluid within the container. In addition, the inherent sealing pressure of the venting check valve is less than the inherent sealing pressure of the transfer check valve which allows air to enter the container due to the pressure differential created as the fluid is displaced.
