Title: Electrode clamping assembly and method for assembly and use thereof
Inventor: CALVISI MICHAEL L
IPC: H05H1/46
Filed: 1996-05-17
Abstract: An electrode clamping assembly for a plasma reaction chamber wherein processing of a single wafer can be carried out. The electrode assembly includes a support member (32), an electrode (30) such as a silicon showerhead electrode in the form of a disk having uniform thickness and a clamping ring (34) which provides a resilient clamping force pressing against the showerhead electrode. The clamping member can be ring of elastically deformable material and the clamping member can be tightened by a plurality of elastic spacedapart bolts (35) such that the clamping member is compressed and provides the resilient clamping force throughout temperature cycling of the electrode assembly during wafer processing. Heat conduction between the showerhead electrode and the support member can be improved by supplying pressurized process gas to a gap therebetween. The clamping member also provides plasma confinement in an area between the electrode and the wafer being processed.
Patent CA-2223758-A1 (CA)
Title: Touch-readable product and associated process
Inventor: YIM JOAN MARILYN
IPC: B41M3/16
Filed: 1996-06-06
Abstract: The economic production of raised printed characters such as Braille is achieved by a "screen printing" process, using a rotational printing machine in combination with high viscosity, "U/V" inks that make possible the depth of deposition and character solidity necessary for achieving the required tactile effect in order to be "readable" by touch.      The high body ink of the thus formed characters is cured comparatively rapidly by exposure to U/V light, so that the high drying rate thus obtained enables the achievement of economically effective rates of production. It is found that raised patterns of significantly lesser prominence than for embossed Braille, as produced by the printing process, are readable on a short-term basis, even by trainee "readers".
Patent CA-2225440-A1 (CA)
Title: A stiffening member to increase fluid flow within a medical device
Inventor: BLEY ROBERT
IPC: A61M25/01
Filed: 1997-12-22
Abstract: The present invention relates to a stiffening member, which is a stylet, that helps increase the fluid flow area within a catheter. In a preferred embodiment, the stylet is made of a single piece of flat rectangular stock that can be twisted to provide equal rigidity in all directions. A cross-section of the stylet reveals that the substantially flat rectangular shape of the stylet permits maximum fluid flow between the stylet and the catheter. This results in increased ease in manipulating and removing the stylet from the catheter. In addition, because the preferred embodiment of the stylet comprises a single element, it is easier to manufacture and should result in lower manufacturing costs. Moreover, the use of the present invention should also result in lower overall health-care costs.

Inventor: PETTIBONE DONALD W
IPC: H05B3/00
Filed: 1996-08-22
Abstract: An apparatus and method for regulating the cooking time for a given recipe for cooking a given food in a lightwave oven is disclosed wherein a microprocessor receives a signal representing the temperature elevation of the oven and the power to the lamps is reduced, either by reducing the intensity of the lamps or turning the lamps off.

Patent CA-2244656-A1 (CA)
Inventor: WAGNER ALBERT L
IPC: C09K8/508
Filed: 1998-08-05
Abstract: The present invention provides a method for reducing the amount of water produced from a subterranean formation as a result of stimulation of the subterranean formation. The method comprises the introduction of a first and second reactive polymer which leak-off into the formation and which are capable of subsequently reacting together to form a reaction product which selectively reduces the permeability of the formation to water flow through the formation. The reactive polymers react in situ to form a reaction product that binds to the formation in such a manner that the flow of water is selectively retarded through the matrix while the flow of oil is substantially unaffected.

Abstract: Un écran d'affichage d'images vidéo est fixé sur un composant chirurgical endoscopique vidéo tel qu'un endoscope vidéo, un instrument chirurgical endoscopique, un support pour coupler l'endoscope et l'instrument, ou une canule au travers de laquelle l'endoscope ou l'instrument passe dans une partie du corps du patient. La fixation se fait au moyen d'un mécanisme d'attache qui peut être ajusté pour permettre de faire varier la position de représentation de l'image vidéo par rapport au composant auquel il est fixé. Selon un autre mode de réalisation, un support sous la forme d'un tube allongé est utilisé pour combiner les mouvements de l'endoscope et de l'instrument endochirurgical qui, au moyen du support, peut être inséré conjointement dans une partie du corps du patient soit directement soit au travers d'une canule, afin de permettre au chirurgien d'actionner tant l'endoscope que l'instrument à l'aide d'une seule main. Un affichage vidéo fixé à l'endoscope ou au support et positionné à proximité de la poignée d'actionnement de l'instrument donne au chirurgien une perspective visuelle similaire à celle qu'il a en chirurgie ouverte.

Title: Temperature activated diversion valve
Inventor: RAY JENNIFER L
IPC: F16K11/04
Filed: 1999-02-08
Abstract: A temperature activated diversion valve for supplying a first inflow fluid as an outflow fluid and for switching to supply a second inflow fluid as the outflow fluid if the first inflow fluid reaches a specified temperature. The temperature activated diversion valve includes a first inflow conduit for carrying the first inflow fluid, a second inflow conduit for carrying the second inflow fluid, an outflow conduit and a valve member. The valve member is moveable between a first position and a second position and establishes fluid communication between the first inflow conduit and the outflow conduit in the first position, while blocking fluid communication between the second inflow conduit and the outflow conduit in the first position. Additionally, the valve member establishes fluid communication between the second inflow conduit and the outflow conduit in the second position, while blocking fluid communication between the first inflow conduit and the outflow conduit in the second position. A biasing element is provided which exerts a biasing force urging the valve member toward the second position and a bonding element restrains the valve member in the first position against the biasing force exerted by the biasing element. The bonding element is thermosensitive to release the restraining of the valve member in the first position upon the bonding element attaining the specified temperature.

Filed: 1999-03-10
Abstract: High viscosity elastomers are often difficult to utilize in rubber compositions without first creating a pre-blend of the high viscosity elastomer and a rubber processing oil to reduce their overall viscosity. This invention relates to utilization of a specialized pre-blend of high viscosity and low viscosity elastomers for use in rubber compositions and to the resulting rubber composition. The use of such resulting rubber composition may be for component(s) of tires, particularly including tire treads. The specialized pre-blend of high and low viscosity elastomers is required to be created by blending individual latices or, alternatively, by blending individual polymerizates of elastomers with diverse viscosities.

Title: Printing and cutting a continuously moving supply of material
Inventor: KEARNEY DAVID A
IPC: B65H20/30
Filed: 1997-09-11
Abstract: Improvements are provided to improve an apparatus and method for processing a substantially constant velocity flow of a web (24) of material, including a cutting mechanism (19) and a web accumulator (19) upstream of the cutter. The improvements include stopping the web by a side surface (38) of the movable blade (164) and configuring the accumulator dimensions and cutting speed to cause an appropriate level of force between the upstream severed end (40) of the web and the blade. Several features achieve a low cutting time and modify cutting force to cut web regions with different characteristics. A low inertia rotary solenoid (Fig. 10) accelerates a blade through the web and against a resilient stop (176, 178). The blade bounces off of the stop (176) to its spring-biased home position. A permanent magnet (180) or electromagnet (182) holds the blade in the home position as solenoid current develops. The result is reduced noise and shorter cutting time.
