Title: Releasable plug connector with fitting indicator
Inventor: HENLIN JEAN-MARTIN
IPC: F16L37/12
Filed: 1997-05-28
Abstract: The proposal is for a releasable plug connector with fitting indicator for connecting fluid lines comprising a tubular insert section (2) with a peripheral securing rib (3), a cylindrical socket housing (1) with a socket (5) for a separate securing component (6) with elastically sprung engagement edges (7) directed radially inwards to engage behind the securing rib (3) after the insertion of the plug component (2) and an indicating component (4) which can be positioned in front of the socket aperture (15) of the housing (1). This consists of two spaced supporting rings (8 and 9) and at least two shoulders (10) joining the supporting rings (8 and 9) together, where one supporting ring (8) can be secured to the front wall (16) of the housing and the other supporting ring (9) away from the housing wall (16) can be supported on the insert section (2) on a flange (12) behind the securing rib (3). The shoulders (10) are formed to be elastically sprung on the opposite faces of the supporting rings (8 and 9) and joined together by outwardly curved bridge shoulders (11) so that, when the insert section (1) is pushed in, the shoulders (10) are pushed outwards and the considerably bowed bridge shoulders (11) project visibly beyond the housing wall (16).

Patent CA-2268763-A1 (CA)
Inventor: GOLEC BRENT LEE
IPC: A61K49/22
Filed: 1997-10-17
Abstract: Microparticles useful for enhancing the ultrasound image of a tissue or organ consist of liquid and/or gas core material which is encapsulated by a biocompatible, tanned protein shell. These stabilized microparticles are useful as ultrasonic imaging agents, and are additionally useful in the further production of functionalized microparticles for in vivo imaging. In particular, targeting molecules such as antibodies or other ligands can be attached to the strengthened exterior surface of the stabilized microparticles to impart target-specificity to the microparticles. The targeting molecules may also provide hydrophilicity to the exterior surface, thus increasing the recirculation time of the microparticles. The targeting molecules may be attached directly to the exterior surface of the microparticles, or they may be attached via a bifunctional spacer arm, which may itself be hydrophilic.  The target-specific microparticles are injected intravenously, allowed to accumulate at the target site, and used to enhance the ultrasound image of a target tissue or organ.

Title: Inlet conveyor for tire testing systems
Inventor: QUINN CHRISTY
IPC: G01M17/02
Filed: 1998-01-22
Abstract: An inlet conveyor for conveying tires through a tire uniformity testing system includes a tire centering mechanism and a pair of conveyor belts for delivering tires to a tire testing station. A fixed conveyor having rollers on which tires can easily slide is secured to a frame that supports the centering mechanism. The conveyor belts are reeved around respective pulleys and are supported by support rails fixed to and extending away from the centering mechanism in cantilever fashion. A conveyor elevator is raised or lowered with respect to the frame unit to raise or lower the support rails and conveyor belts to either engage or disengage a tire resting on the fixed conveyor. The support rails and conveyor belts are adjustable in a lateral direction to vary the width of the space between the belts to accommodate different size tires. The conveyor belts are advanced by a rotary pneumatic actuator that precisely controls the distance the belts move to position the tire with respect to the testing station. The inlet conveyor is mechanically isolated from the testing station so that disturbances affecting the inlet conveyor are not transmitted to the testing station. The inlet conveyor is movable with respect to the testing station to reverse the direction of tire flow through the testing machine.

Patent CA-2280724-A1 (CA)
Title: Desulfurization process for removal of refractory organosulfur heterocycles from petroleum streams
Inventor: KRYCAK ROMAN
IPC: C10G45/60
Filed: 1998-02-26
Abstract: Hydrocarbon feeds are upgraded by contact of the stream under hydrodesulfurization (HDS) conditions with a catalyst system comprising a sulfided transition metal promoted tungsten/molybdenum HDS  catalyst, e.g., Ni/Co-Mo/A 12O3 and a solid acid catalyst which is effective for the isomerization/disproportionation/transalkylation of alkyl substituted, condensed ring heterocyclic sulfur compounds present in the feedstream, e.g. zeolite or a heteropolyacid compound.  Isomerization, disproportionation and transalkylation reactions convert refractory sulfur compounds such as 4- or 4,6-alkyl dibenzothiophenes into corresponding isomers or disproportionated isomers which can be more readily desulfurized by conventional HDS catalysts to H2S and other products. A hydrocarbon feed is first passed to a hydrotreating reactor (1). The effluent from the hydrotreating reactor (1) goes through a high-pressure gas-liquid separator (2) and is passed to a fractionator (3). The fractionator bottoms are passed to reactor (4) and effluent from reactor (4) is recycled to hydrotreater (1).

Patent CA-2293936-A1 (CA)
Inventor: LINDSTROM DAVID ERIC
IPC: G05D23/19
Filed: 2000-01-05
Abstract: A control system and method provide a multiple option select function in which an option select resistor acts as a selector. The control system determines the resistance value of the resistor and maps the resistance value to a data entry in an option select table. The index of the data entry is determined and used to reference option parameters in at least one option parameter table. The index allows the control system to select an option parameter from many possible option parameters in the option parameter table. Furthermore, additional option parameter tables may also be referenced to select multiple option parameters using a single select resistor. The control system is disclosed as controlling a water heater system, although such control systems may be used to control other systems, such as furnaces and hydronic heating and water systems. A calibrating circuit is used to measure a transient response of an RC circuit. The resistance of the option select resistor is determined from its transient response relative to resistors in the calibration circuit.

Title: Method of preparing a transgenic non-human animal expressing p25
Inventor: MCNEISH JOHN DOUGLAS
IPC: C12N15/12
Filed: 2000-02-03
Abstract: The invention provides transgenic, non-human animals and transgenic non-human mammalian cells harboring a transgene encoding a p25 (activator of the protein kinase cdk 5) polypeptide.   The two neuropathological lesions associated with Alzheimer's disease (AD) are amyloid plaques and neurofibrillary tangles (NFTs), composed predominantly of amyloid .beta. peptides and hyperphosphorylated tau, respectively. While animal models for plaque formation exist, there is no animal model that recapitulates the formation of NFTs. This invention provides transgenic mice that overexpress human p25, an activator of cdk5, resulting in tau that is hyperphosphorylated at AD-relevant epitopes.  Deposition of tau is detected in the amygdala, thalamus and cortex. Increased phosphorylated neurofilament, silver-positive neurons and neuronal death are also observed in these regions.  We conclude that the overexpression of p25, an activator of cdk5, is sufficient to produce hyperphosphorylation of tau and neuronal death. The p25 transgenic mouse represents the first model for tau pathology in AD.

Abstract: A toolholder (1) is provided for receiving, pressurizing, and conducting an external stream (3) of coolant to a rotating cutting tool without mechanical containment between the toolholder (1) and the coolant stream (3). The toolholder (1) includes a shank (9) attachably connectable to a rotatable drive shaft, an adapter (11), such as a collet chuck (31), for connecting a rotatable cutting tool to the shank (9), and a coolant inducer (13) mounted between the shank (9) and the adapter (11). The coolant inducer (13) is formed from an impeller assembly (15) having a plurality of uniformly spaced, coolant receiving openings (54) around its periphery for receiving an uncontained coolant stream. A passageway (16) is provided along the axis of rotation of the adapter (11) for receiving and conducting the coolant pressurized by the impeller assembly (15) to a cutting tool secured in the adapter (11). The impeller-type coolant inducer eliminates the need for fluid seals or other friction-generating mechanical interfaces between the rotating toolholder and the source of pressurized coolant.
