Abstract: Cette invention concerne des procédés d'analyse de banques de modulateurs candidats de voies de transmission de signalisation intracellulaire. Ces procédés permettent d'évaluer l'aptitude des candidats contenus dans la banque à inhiber la liaison de peptides constituant des participants dans les processus de signalisation, soit en qualité de protéine génératrice de signaux, soit en qualité de son partenaire correspondant de liaison à un site non catalytique. Des peptides spécifiques pouvant être utilisés à cette fin ont été identifiés. Dans une application, les modulateurs du système immunitaire peuvent être identifiés en déterminant l'aptitude de substances candidates à modifier l'interaction entre une protéine-kinase C-thêta (PKC-thêta), ou l'un de ses fragments, et son élément correspondant. Cette interaction peut être mesurée en utilisant la liaison de l'élément correspondant comme un indice, ou encore, en s'appuyant sur une réponse physiologique.

Abstract: The invention describes a process for the preparation of a natural fiber and thermoplastic composite and the resulting products therefrom. The process includes the steps of mixing the natural fiber and the thermoplastic in a blender with a porosity aid and an interfacial agent to form a mixture; adding the mixture to a heated extruder; compressing the mixture with an extruder screw having a plurality of flight sections, at least one of the flight sections serving as a compression flight section which compresses the mixture by having its flight spaced closer together than other adjacent flight sections, and at least one other vent flight section which allows gaseous reaction products to be removed from the extruder through a vent in the extruder by having its flight spaced farther apart than the compression section, the vent flight section being positioned after the compression flight section; extruding the mixture through an extrusion die as a composite; and shaping the composite in a vacuum calibration device to a desired profile. The process further includes the step of co-extruding a second thermoplastic onto the natural fiber/thermoplastic composite for some applications (e.g., windows, doors and siding).

Inventor: BENSON DAVID K
IPC: G02B6/42
Filed: 1997-02-20
Abstract: A fiber-optic device (10) for sensing the presence of a gas in an environment is provided. The device (10) comprises a light source (14) for directing a light beam (36) to a layer system having a first surface (46) and a second surface (54) opposite to the first surface.  The first surface (46) is exposable to the light beam (36) and the second surface is exposable to the environment. A first light portion (50) encounters and reflects from the first surface (46) at an angle of incidence free from optical wave guide resonance phenomenon and the second light portion (52) encounters and reflects from the first surface (46) at an angle of incidence enabling an optical wave guide resonance phenomenon. The layer system is selected to reversibly react with the gas to be detected. The reaction between the gas and the material changes the material's optical properties and the wavelength at which the optical wave guide resonance occurs. Furthermore, a mechanism (24, 26, 28) for measuring the intensity of the reflected first light portion (50) relative to the reflected second light portion (52) is provided with the ratio of the first and second light portions indicating the concentration of the gas presence in the environment.

Title: Magnetic particle damper apparatus
Inventor: AGNIHOTRI ASHOK K
IPC: F16F7/00
Filed: 1998-11-24
Abstract: A magnetic particle damper apparatus is provided for damping motion between two relatively movable members.      The damper apparatus comprises first and second conductor members each attachable to one of the relatively movable members. The conductor members are disposed with confronting surfaces having a gap therebetween filled with a quantity of magnetic particles. A magnetic element is attached to one of the conductor members, producing magnetic flux which is substantially confined to a magnetic flux path defined by relatively magnetically permeable regions and relatively magnetically non-permeable regions of the conductor members to flow across the gap and through the magnetic particles. The magnetic field causes the magnetic particles along the flux path to adhere to one another and to the confronting surfaces of the conductor members producing a force opposing relative motion between said movable members and dissipating energy when the conductor members move relative to one another.
Patent CA-2254770-A1 (CA)
Title: Downhole tool
Inventor: LENN CHRISTOPHER PETER
IPC: E21B47/10
Filed: 1997-05-20
Abstract: When an oil well has been completed it is necessary to monitor downhole the rate at which the well's products are flowing along the borehole and up to the surface. One type of method and apparatus previously proposed for this purpose in wells with a horizontal borehole section, where the fluid is stratified into distinct component layers, involves the use of tracer or maker materials; employing an injector/detector tool a suitable material is injected into the fluid, and its arrival time at a downstream detector station is noted, giving the flow velocity by a distance-over-time type calculation. The problem, however, is to get the tracer/marker material, in the form of a suitably soluble (or miscible) composition, into the well fluid in such a way that it ends up in the desired component layer; unfortunately, merely introducing the composition randomly into the fluid somewhere across the borehole is not satisfactory, for if injected into the "wrong" layer it is in practice difficult for the tracer composition to migrate to its intended target. The invention seeks to solve this problem by proposing the use of an injection apparatus that comprises a plurality of spaced ejection ports (221p, 22r) (from which the relevant tracer composition can be ejected so as to be injected directly into the relevant chosen component layer), together with orientation means (15) whereby in use the orientation of the tool can be so adjusted that the ports are so disposed as concurrently to lie each within the appropriate layer. Each port is connectable to a source of the relevant tracer composition; most conveniently the source is the combination of a reservoir (131, 13r) and a syringe-like device (121, 12r) which can draw a suitable amount of the composition from the reservoir and then drive it to, and eject it from, the associated port into the chosen layer.

Abstract: A turning-aid nozzle mounted in the region of the outlet of a watercraft's propulsion system comprises a starboard inner surface and a port inner surface protruding radially inwardly from the nozzle in such a manner as to obstruct the flow of water from the watercraft's propulsion system.  When turning to port, the starboard inner surface obstructs a portion of the water jet exiting the propulsion system, thereby producing an additional turning  moment  that  aids  the  nozzle  in  turning  to  port.          Similarly, when turning to starboard,  the port inner surface obstructs a portion of the water jet exiting the propulsion system, thereby producing an additional turning moment that aids the nozzle in turning to starboard.

IPC: B29L9/00
Filed: 1998-12-29
Abstract: A  process  which  allows  elastomeric  materials  of different   colors,   durometers   and/or   other  material characteristics to chemically bond to one another so as to eliminate  any possibility of  delamination.   Latex-based liquid  elastomer  solutions  having  different  material characteristics are applied sequentially to a heated mold to form a series of layers making up the article,  with rapid partial curing taking place between each application; the partial curing forms a skin coat over each layer which prevents intermixing of the different solutions, but which still permits a chemical bond to form during full curing of the  materials.    The  process  applies  equally  to  dip (immersion) molded and flat molded goods.   An example of the invention as it relates to flat-molded goods is an athletic shoe sole, and an example as it relates to dip-molded goods is a resilient,  one piece watersports boot which can be fitted over a human foot without a zipper.
