Patent CA-2129874-C (CA)
Inventor: DOUGLAS RICHARD M
IPC: C23C4/10
Filed: 1994-08-10
Granted: 1999-07-20
Abstract: A powder for use in a thermal spraying coating process comprises particles consisting essentially of a metal carbide core coated at least partially with a layer consisting essentially of a nickel-chromium alloy containing the metal carbide dissolved therein.  The particles are formed by heating a mixture of fine starting particles of the metal carbide in the presence of the nickel-chromium alloy under conditions effective to cause a portion, preferably 60 to 90 wt.%, of the starting metal carbide to dissolve in the Ni-Cr alloy.  In an alternate embodiment suitable for higher temperature application, more than 90 wt. % of the starting carbide particles are dissolved.  As the amount dissolved approaches 100 wt.%, the core essentially disappears. Coatings formed according to the invention show an unexpectedly large increase in both smoothness and erosion resistance.

Abstract: La présente invention concerne l'apport de molécules cargo biologiquement actives, telles que des polypeptides et des acides nucléiques dans le cytoplasme et les noyaux de cellules in vitro et in vivo, grâce à l'emploi de nouveaux polypeptides de transport qui comportent une ou plusieurs parties de la protéine tat du VIH et qui se fixent par covalence aux molécules cargo. Ces polypeptides de transport sont caractérisés par la présence de la région basique tat (acides aminés 49-57), l'absence de la région riche en cystéine (acides aminés 22-36) et l'absence du domaine carboxy-terminal, encodé en position 2 par l'exon tat (acides aminés 73-86), de la protéine tat se rencontrant à l'état naturel. L'absence de la région riche en cystéine constatée dans les protéines tat classiques résout les problèmes de fausse transactivation et d'agrégation des ponts disulfure.

Title: Connection release in a telecommunications system
Inventor: CHOTAI SUNIL
IPC: H04B7/26
Filed: 1995-05-26
Granted: 1999-11-16
Abstract: In a telephone network, e.g. a cellular radio system, after a transaction (e.g. a call) has ended, the connection is not fully released. If another connection is to be setup on ending of a current call, e.g. a voice message or call completion to be a subscriber arrangement, a flag F is set in the connection management system CM. The status of the flag F is used to determine if the signal in connection towards a termination B should be kept or released immediately. Depending on the stems of flag F different actions are taken in the network. The connection may Ix maintained for a predetermined interval. Data F, F1, F2, concerning the slams of the flags are transmitted from switching centre MSC1 to another switching centre MSC2 if control of the network termination is transferred. If control of the network termination B passes to a switching centre not capable of supporting the service to which the flag F1 relates, the flag slams is stored in a buffer register HLR associated with the user until such time as it is again connected ro a switching centre capable of supporting the service.

Title: Intelligent pbx in-building and out-of-building personal reach communications system
Inventor: FOLADARE MARK JEFFREY
IPC: H04Q3/62
Filed: 1997-05-14
Granted: 2000-10-10
Abstract: A call placed by a calling party from within the local office or campus area served by an intelligent PBX of a called party who is a subscriber to a personal reach service is held at that PBX for determination of whether the called party/subscriber is within or outside the local area served by the PBX. This determination is made using two-way paging technology through which a pager-carrying called party/subscriber is determined to be within the local area if the two-way pager carried by the called party/subscriber is registered within the area. If the called party/subscriber is determined to be within the local area, then a local page is broadcast to the called party/subscriber and a return call to the PBX by the called party/subscriber is bridged with the call being held from the calling party at the PBX. If the called party/subscriber is determined to be outside the local area, then the calling party's call is connected over the telephone network to the called party/subscriber's personal reach service network platform. A nationwide page is broadcast and a return call from the called party/subscriber to the network platform is bridged with the calling party's call to complete the connection between the calling and called parties.

Granted: 2002-11-19
Abstract: A drive unit for driving a press uses a hydraulically actuated oil shear brake unit located on one side of a flywheel and a hydraulically actuated oil shear clutch unit located on the opposite side of the flywheel. The actuating assemblies for the oil shear brake unit and the oil shear clutch unit are supplied as complete assemblies which are secured to the brake housing and clutch housing, respectively, at the time of assembly of the units to the press. The actuation of the clutch unit and the brake unit occur simultaneously and from the same hydraulic pressure source such that the overlap between the two units is controllable from no overlap to a specified amount of overlap where the brake unit is applied simultaneously with the engagement of the clutch for a specified amount of time. The stroke acquired by the brake and clutch actuating assemblies can each be selected at the time of assembly by selecting the appropriate width for a plurality of spacers.

Granted: 2001-09-11
Abstract: A method of maintaining a laser weapon target aim point. The method includes the step of selecting an aimpoint (42) on a target (24). The target is then engaged with a laser beam (23). The tracker (36) then receives target scene information, and detects both a target image and a target laser hit spot (40). The tracker (36) then determines the vector distance between the target aimpoint and the target laser hit spot, and drives the vector distance (70) to zero to close the loop between the target aimpoint and the target laser hit spot location. The method and system of the present invention thereby increase the probability of a target kill by enabling the tracking system to maintain a laser lock on the target aimpoint from an initial target engagement to a target kill stage.
