Patent CA-2281567-A1 (CA)
Title: Self-regulated apoptosis of inflammatory cells by gene therapy
Inventor: TATAKE REVATI J
IPC: A61K48/00
Filed: 1998-02-27
Abstract: This invention relates to the therapeutic induction of apoptosis in activated inflammatory cells, or cells at a site of inflammation, by introducing into those cells a chimeric gene containing an apoptosis-inducing gene (AIG) driven by a promoter of an inducible gene activated in inflammation and a promoter enhancer such that the inflammatory cells are targeted. In one embodiment, the chimeric gene comprises at least one TNF.alpha. promoter enhancer attached to a functional copy of a minimal TNF.alpha. promoter and further attached to at least one copy of an apoptosis-inducing gene, wherein expression of the gene is driven by the TNF.alpha. promoter. Attachment can be direct, distal, proximal or combinations thereof. Example apoptosis-inducing genes include caspase 3, caspase 4, caspase 5, Granzyme B. Advantageously, the TNFp-AIG  chimeric gene is expressed in only those cells producing the inflammatory cytokine, TNF.alpha.. In addition, the TNFp-AIG chimeric gene also sequesters inducible TNFp transcription factors, thereby reducing endogenous production of TNF.alpha.. The invention also relates to methods of making and using self-regulated apoptosis chimeric genes and pharmaceutical compositions containing them for treating inflammatory diseases.
Patent CA-2282958-A1 (CA)
Title: Releasable retention assembly for temporarily retaining utility pole covers
Inventor: REYNOLDS WILLIAM E
IPC: F16G11/10
Filed: 1999-09-21
Abstract: A releasable retention assembly includes an elongated flexible member, a retention member and a lock mechanism. The flexible member has opposite end portions and a length sufficient for wrapping at least once about an utility pole to retain a cover in place on the utility pole. The retention member is secured to one opposite end portion of the flexible member and defines a slot through which the other opposite end portion of the flexible member can extend. The lock mechanism includes a latch element mounted to the retention member for undergoing pivotal movement between angularly displaced latched and unlatched positions relative to the other opposite end portion of the flexible member extending through the slot of the retention member. In the latched position the latch element is engaged with and wedges the flexible member within the slot against the retention member to thereby hold the other opposite end portion of the flexible member stationary in relation to the retention member and maintain the flexible member tightened about the utility pole. In the unlatched position the latch element is disengaged from and unwedges the flexible member within the slot to thereby allow the flexible member to loosen about the utility pole. The lock mechanism also includes a spring element biasing the latch element to the latched position and a release lanyard that may be actuated to move the latch element from the latched position to the unlatched position.
Patent CA-2284699-A1 (CA)
Inventor: POPOV SERGUEI A
IPC: F04F5/46
Filed: 1999-01-26
Abstract: The present invention pertains to the field of jet-generation techniques and relates to an operation method which essentially comprises supplying a gas-liquid flow from an ejector into a supersonic-flow conversion chamber. The gas-liquid flow is submitted to a sudden expansion in said chamber so as to provide, due to its reduced density, a subsonic or supersonic flow mode. The gas-liquid flow is then slowed down by a pressure jump. This invention also relates to a device for realising this method, wherein said device essentially consists in an apparatus which comprises a supersonic-flow conversion chamber.  The chamber has its inlet connected to the outlet of an ejector, while its outlet is connected to a separator. The supersonic-flow conversion chamber is made in the shape of a profiled channel widening step by step in the flow direction. This operation method and the above-mentioned characteristics provide for a more reliable operation of the pumping-ejection apparatus.

Title: Foam coated convoluted tubing
Inventor: FATATO FRANCIS B
IPC: F16L57/00
Filed: 1998-05-29
Abstract: Convoluted tubing (10) for automotive wiring harnesses and other elongated substrates is provided with sound dampening qualities by filling the valleys (20) between convolutions (18, 20) with a flexible, resilient foamed composition, such as silicone rubber, and foaming the composition to cause expansion of the foam so that ribs (22) of foam project radially from the valleys. In a preferred embodiment, spaced apertures (26) are formed in the valleys (20) to allow the expanding foam to form radially inwardly projecting fingers (24) which contact the wiring harness and act to dampen vibrations.  The corrugated tubing may be axially slit (16) and the slit allowed to be filled with the foamed composition which, when foamed, eliminates noises caused by movement of the edge surfaces of the slit when torsional forces are applied to opposite ends of the tube (14).

Title: Electric plug and socket assembly
Inventor: TLUCZYKONT STEFAN
IPC: H01R13/506
Filed: 1998-09-04
Abstract: In order to reliably lock an electric plug and socket assembly comprising an outer part and an inner part which can be coupled to the outer part, the inner part is provided with a recess into which, when the two parts are coupled, a snap-on hook means is engaged and maintained so as to act as a spring. When the plug and socket assembly is in a locked position, the snap-on hook means or each snap-on hook means is locked against radial excursion since it rests on a bushing which is axially displaceable on the outer part. In the unlocked position, the backward pulled bush releases the snap-on hook means thereby allowing for disengagement of the outer and inner parts. In order to enable the plugging of the parts when the bushing is in the locked position, the snap-on hook means is provided with two spring legs whose end cam and an inner contour running into the recess of the inner part form a guide for the two leg snap-on hook means.

Title: An advanced technology pollution free, highly efficient industrial power generation system
Inventor: BEICHEL RUDI
IPC: F02C3/30
Filed: 1998-10-27
Abstract: A low pollution gas generator includes a source of a mixture of oxygen rich gas and fuel, the oxygen rich gas having less nitrogen than air and more oxygen than air. The mixture is passed into a combustion chamber where it is ignited. The premixing of the oxygen and fuel prior to entering the combustion chamber allows for more efficient combustion. Water is used as a heat absorbing agent. The mainstream gases from the combustion chamber expand through a primary turbine and then are reheated before expanding through a secondary turbine. Heat from the mainstream gases is transferred to an auxiliary flow of water which becomes steam and is expanded through an auxiliary turbine. The system of the present invention may obtain efficiencies of 65 % or even higher. Furthermore, this system provides little or no pollution and is compact compared to industrial power generation systems of similar power output.
Patent CA-2307944-A1 (CA)
Title: Anti-rattle trailer hitch
Inventor: YOUNG DAVID A
IPC: B60D1/14
Filed: 2000-05-08
Abstract: A hitch assembly generally includes a hitch receiver that retains an insert by a pin.    The pin is preferably hook-shaped and includes a primary pin segment and an engagement terminus. The primary pin segment defines a primary axis transverse to the common longitudinal axis of the hitch assembly. When assembled, the primary segment passes through an aperture located in a first wall of the hitch receiver, the insert aperture of the insert and another aperture in the second wall of the hitch receiver.  As a fastener is threadably engaged with a threaded portion of the pin, the fastener pulls the primary pin segment through the hitch receiver and drives the engagement terminus through the second aperture against the insert. The fastener thereby introduces tension in the pin to restrict movement of the insert relative to the hitch receiver and minimize free-play therebetween. In one embodiment, a tamper resistant secondary retainer provides a lock which engages a conical end of the pin.
