Title: Composite microporous carbons for fuel gas storage
Inventor: AMANKWAH KWABENA
IPC: B01J20/20
Filed: 1996-08-19
Abstract: A method of making a microporous carbon material which includes providing a precursor selected from the group consisting of crystalline salts of aromatic sulfonates and nonporous polymeric salts. Prior to carbonization, the precursor is treated by ion exchange or other conventional processes to introduce a metal such as iron, nickel and cobalt into the precursor. Heat treatment of such composite precursors in the temperature range of 350 to 850 ~C in an inert oxygen free atmosphere for a sufficient time promotes thermally induced hydrogen abstraction and rearrangement of BSUs which result in the formation of a composite, carbonaceous microporous material which contains a metal component, and has a pore size distribution in the range of about 4-15 .ANG.. The structural and storage characteristics of the microporous carbon materials are also disclosed.

Title: Method and apparatus for wireless communication employing collector arrays
Inventor: SMITH BRUCE DENIS
IPC: H04B7/02
Filed: 1996-10-15
Abstract: A cellular communications system that includes forward channel communications to users and corresponding reverse channel communications from mobile users.  The users travel from one area to another area over one or more zones. The forward channel communications are broadcast directly to users in a broadcaster zone. The reverse channel communications from users are not returned directly but are first collected at locations arrayed over the broadcaster zone. After collection, the reverse channel communications are forward to complete the full duplex communications. The forward channel communications are point to multipoint while the reverse channel communications are multipoint to point. The communication system separately handles the point to multipoint forward path as a direct broadcast and the multipoint to point reverse path using multiple collection points. Since the forward and reverse paths are separately configured, the present invention optimizes both the forward and reverse paths.

Abstract: A process for oxygen-enriching a first feed gas stream be fed into a furnace by utilizing an oxygen-enriched gas stream from a second feed gas stream, wherein the first feed gas stream is compressed and then heated prior to injection into the furnace. The second feed gas stream is separated using an ion transport module containing an ion transport membrane having a retentate side and a permeate side to produce an oxygen-depleted gas stream on the retentate side and the pure oxygen gas stream or the oxygen-enriched gas stream on the permeate side.  The pure oxygen gas stream or the oxygen-enriched gas stream is added to the first feed gas stream at any location before the first feed gas stream enters the furnace.
Patent CA-2239486-A1 (CA)
Inventor: FRIESEN ARNOLD
IPC: A63B63/00
Filed: 1998-06-03
Abstract: A game target can be used by a single individual for practising skills in a game that involves the throwing of an object to a particular position on a playing surface. One example is curling. The target includes a rail that is supported to extend laterally across and above the game surface. A target element depends from the rail. In preferred embodiments the target element can be positioned at any desired location along the rail. This allows an individual to practise alone, without another party to hold the target, e.g. a broom in curling. The movement of the target element along the rail may be accomplished with a carriage mounted on the rail for movement along the rail and with the target element depending from the carriage. A further improvement is achieved where the target includes a carriage drive for controllably moving the carriage to any selected position along the rail.  Embodiments of the invention with the carriage drive may include a remote control means for the carriage drive.

Patent CA-2246196-A1 (CA)
Inventor: CAHILL DREW E
IPC: E21B33/08
Filed: 1998-09-01
Abstract: Apparatus and method are provided for protecting a reciprocating polish rod from suffering circumferential scoring when it is rotated by a rod-rotator while misaligned and in contact with the carrier bar of a pump jack. A  cylindrical sleeve is inserted through the bore of the carrier bar and any additional stacked components supported thereon. An upset at the top of the sleeve retains it within the bore of the carrier bar and any stacked components. The bottom end of the sleeve extends substantially to the bottom of the carrier bar. The polish rod is installed through the bore in the sleeve and can slide and rotate therein. The polish rod is suspended from the carrier structure with a rod clamp. The sleeve guides the polish rod through the carrier structure without permitting accidental contact of the polish rod and the carrier structure and thereby prevents circumferential scoring of the polish rod when the rod is rotated by the rod-rotator.

Patent CA-2255244-A1 (CA)
Inventor: COOPER GREGORY L
IPC: A23L5/10
Filed: 1998-12-03
Abstract: Apparatus for feeding and cooking raw product, such as shellfish and the like, in a continuous process. A preferred version of the apparatus includes a feed tank with raw product immersed in a bath. A conveyor follows an inclined path starting in the feed tank and exiting the surface of the bath to convey raw product out of the tank and through a cooking chamber. A feed control mechanism is provided to allow for accurate setting of product flow.  The mechanism includes a rocking paddle extending just above the conveying surface of the conveyor. The paddle is linked to a rotary drive train by a linkage consisting of two pivotally attached arms. Rotation of the drive train causes the paddle to rock and deposit product on the conveyor during each stroke. The drive train is mounted on a slidable support that is pivotally attached to an adjustment rod. The other end of the adjustment rod includes an adjustment handle and a micrometer-style adjustment with clearly visible indicia for adjusting product flow. As the adjustment rod is rotated, the drive train translates and changes the reference angle between the two arms of the linkage, which moves the paddle closer or farther from the conveying surface to adjust the amount of raw product deposited on the belt during each stroke. A cover over the feed tank provides a seal to prevent cooking steam from escaping the cooking chamber through the feed tank.

Title: Process for halogenation of isomonoolefin/para-alkylstyrene copolymers
Inventor: CHUNG DAVID YEN-LUNG
IPC: C08F10/10
Filed: 1997-07-18
Abstract: A process for halogenating a copolymer of a C4-C7 isomonoolefin, e.g.  isobutylene, and a para-alkylstyrene, e.g., para-methylstyrene, is disclosed.  Increased halogenation efficiency is achieved by conduction the reaction under free radical halogenation conditions and in the presence of an oxidizing agent, e.g. hydrogen peroxide, which oxidizes hydrogen halide generated in situ in the reaction back to free halogen. The oxidizing agent is preferably not added to the reaction medium until after first stage halogenation is substantially completed.

Abstract: Disclosed is a method for reducing the sterol, for example cholesterol, content of sterol-containing substances such as fats and oils. The method provides an efficient and cost effective process based on the phospholipid bilayers. Phospholipid aggregates are contacted with, for example, a sterol-containing fat or oil in an aqueous environment and then mixed. Following adequate mixing, the sterol-reduced fat or oil is separated from the aqueous separation mixture as shown in the figure. Alternatively, the corresponding sterol-enriched phospholipid also may be isolated from the aqueous separation mixture.
