Title: Method for access control in a multiple access system for communications networks
Inventor: CHUAH MOOI CHOO
IPC: H04L12/56
Filed: 1998-10-08
Abstract: A method for access control in a wireless network having a base station and a plurality of remote hosts includes the optional abilities of making dynamic adjustments of the uplink/downlink transmission ratio, making dynamic adjustments of the total number of reservation minislots, and assigning access priorities by message content type within a single user message stream. The method of the invention further provides for remote wireless host paging and for delayed release of active channels by certain high priority users in order to provide low latency of real-time packets by avoiding the need for repeated channel setup signaling messages. In the preferred embodiment, there are N minislots available for contention in the next uplink frame organized into a plurality of access priority classes. The base station allows m access priority classes. Each remote host of access priority class i randomly picks onecontention minislot and transmits an access request, the contention minislot picked being in a range from 1 to N i where N(i+1) < N i and N 1=N. In an alternate embodiment of a method for access control according to the present invention, each remote host of access priority class i and with a stack level that equals 0, then transmits an access request with a probability P i where P(i+1) < P i and P1 = 1.

Title: Injection molding cooling core having a ribbed cap
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/73
Filed: 1998-12-07
Abstract: Injection molding apparatus with each elongated cooled mold core (10) having a number of cooling fluid bores (118) or grooves (134) extending around a central cooling fluid duct (104). An integral dome shaped front cap (76) encloses the open front end (78). The inner surface (130) of the dome shaped cap (76) has curved ribs (132) which form curved cooling fluid grooves (134) aligned with the cooling fluid bores (118) or grooves (134). The curved ribs (132) give the dome shaped front cap (76) more strength which allows it to be thinner with the curved cooling fluid grooves (134) being closer to the cavity (66) to improve cooling efficiency.

Title: System for genetically treating cardiac conduction disturbances
Inventor: MORISSETTE JOSEE
IPC: A61K48/00
Filed: 1997-04-04
Abstract: The present invention provides delivery systems for delivering conduction protein genetic material to cardiac cells in localized areas of the heart to improve the conductance therein. More specifically, there is provided a system for delivering connexin proteins or nucleic acid molecules encoding connexin proteins to a site in the heart which has been determined by mapping procedures to have a conduction disturbance. For cases where conduction is impaired, selected genetic material is delivered by Applicants' delivery system to cells around the disturbance area, in order to enhance overall conductivity patterns; in other cases, genetic material is selected to slow conduction in affected areas, so as to prevent, e.g., brady-tachy syndrome.
Patent CA-2260892-A1 (CA)
Title: Appetite suppression
Inventor: JARMEL MARK E
IPC: A61K31/198
Filed: 1997-07-16
Abstract: A method and composition for reducing appetite and carbohydrate craving using precursors for the neurotransmitters serotonin, dopamine, norepinephrine and histamine, which include the precursors tryptophan, phenylalanine, tyrosine and histidine. The precursors are combined together and with xanthines for synergistic effect permitting advantageously lower doses of the precursors. Concomitant administration of histidine with any of tryptophan, phenylalanine and tyrosine produces a potentiated effect in appetite suppression. Xanthines, including theobromine, caffeine and cocoa, act as potentiators of the precursors, individually and in combinations of precursors. Separate formulations with xanthines of tyrosine and/or phenylalanine are used conjointly with a formulation of tryptophan with xanthines, each administered separately at intervals of at least 20 minutes. Hydrolyzed protein is utilized as a natural tryptophan source for the combinations, together with an insulin producing carbohydrate to remove from the blood stream other amino acids competing for transport across the blood-brain barrier. Alternatively, unhydrolyzed protein may be administered along with a proteolytic enzyme to produce tryptophan in the gastrointestinal tract.

Title: Method of manufacturing porous electrode wire for electric discharge machining and structure of the electrode wire
Inventor: SEONG KI CHUL
IPC: B23H7/08
Filed: 1998-07-30
Abstract: A method of manufacturing a porous electrode wire for electric discharge machining, comprising passing a wire rod comprising a first metal containing copper through a plating bath of a second metal having a vaporizing temperature lower than that of the first metal to form on a surface of the wire rod an alloy layer having a hardness higher than those of the first and second metals and an elongation percentage lower than those thereof by a diffusion reaction of the first and second metals, forming a layer of a plating metal comprising the second metal on a surface of the alloy layer, and then drawing the resultant wire rod to form cracks in the alloy layer and the plating metal layer. This electrode wire has an improved working rate at least 15 % higher than that of a regular zinc-plated electrode wire and such an improvement of the working rate is ascribed to an increase in the surface area of the electrode wire owing to a porous structure of the surface thereof which in turn increases a rate of cooling the electrode wire with a working fluid.
