Title: Formulated lubricant oils containing high-performance base oils derived from highly paraffinic hydrocarbons
Inventor: BAILLARGEON DAVID J
IPC: C10M143/06
Filed: 2001-01-26
Granted: 2010-04-13
Abstract: The present invention relates to formulated lubricant oils derived from a highly paraffinic basestock. The formulated lubricant oils of the present invention comprise a wax isomerate paraffinic hydrocarbon basestock component in which the extent of branching, as measured by the percentage of methyl hydrogens (BI), and the proximity of branching, as measured by the percentage of recurring methylene carbons which are four or more carbons removed from an end group or branch (CH2 > 4), are such that: (a) BI - 0.5(CH2 > 4)15; and (b) BI + 0.85(CH2 <<45; as measured over the hydrocarbon basestock as a whole. Preferably, the wax isomerate basestocks to be used in the lubricating oils of the present invention have a biodegradability value of at least 50 % under OECD 301 B test. In addition, these basestock components have pour points of about -25 °C or lower. They are also characterized by unexpectedly good low-temperature and high-temperature viscosities, with CCS viscosity at -15 ° more than about 3 500 cP, and with a kinematic viscosity at 100 °C of about 5 cSt or greater. Desirable multigraded oils obtained using these basestocks may include OW-, 5W-, 10W-, and 15W-XX grades (XX=20-60).

Abstract: A method and system for commanding and controlling diverse home devices. A first home device capable of displaying user interface data is connected to a home network. A second home device stores user interface data that defines a user interface for commanding and controlling the second home device, also connected to the home network. The first device receives the user interface data from the second device over the network. The first device then displays the user interface as defined by the data. The user interacts with the user interface displayed on the first device by a control device. User input is accepted from the user responsive to the interaction. Control and command information is sent from the first home device to the second home device in order to control the second device according to the user input. Since the user interface can be displayed from any device, a single control device may control a plurality of different devices without requiring any change in the mode of operation of the control device.

Title: Resilient cutting blades and cutting devices
Inventor: DETORRE ROBERT P
IPC: B26D7/26
Filed: 2002-09-16
Granted: 2009-06-02
Abstract: Steel reinforced tire fabrics are cut with long rigid bar blades, circular disc blades sand disc and anvil blades. All of these blades may have an open relatively deep slot spaced close to the cutting edge that creates a resilient cantilevered spring element that includes the cutting edge. In response to cutting forces, the spring element will deflect and form a concave crossover area that improves cutting. A supporting material, particularly a precompressed supporting material, such as a precompressed or stretched polyurethane strip may be inserted into the slot. The supporting material limits or reduces the deflection of the spring element so that the yield strength of the spring element is not exceeded and it returns to its original position when the forces are removed. A precompressed supporting material exerts an outward force on the spring element. A polyurethane strip may be precompressed by stretching it before it is inserted into the slot. Two overlapping blades are used to cut the tire fabric, one or both can have the resilient spring features. More than one slot may be provided in a blade so there is more than one spring element in one blade. The blades can be used to cut other materials.

Title: Method and apparatus for reducing a copy protection process by a relative increase in composite sync amplitude
Inventor: QUAN RONALD
IPC: H04N5/913
Filed: 1994-05-09
Granted: 2005-08-02
Abstract: Enhancements to a video anticopying process that causes an abnormal low amplitude video signal to be recorded on an illegal copy. The enhancements in one version introduce into the overscan portion of the television picture, just prior to the horizontal or vertical sync signals but in active video, a negative going waveform that appears to the television receiver or video tape recorder to be a sync signal, thereby causing an early horizontal or vertical retrace. One version provides (in the right overscan portion of the picture), a checker pattern of alternating gray and black areas which causes the TV set on which the illegal copy is played to horizontally retrace earlier than normal in selected lines with a consequential horizontal shift of the picture information on those lines. This substantially degrades picture viewability. In another version a gray pattern at the bottom overscan portion of the picture causes vertical picture instability. In another version selected horizontal sync signals are narrowed, causing irregular vertical retraces.      Also provided is apparatus for removing or attenuating these enhancements from the video signal, to allow copying.

Abstract: La présente invention se rapporte à des techniques de chirurgie effractive minimale. Elle concerne un procédé de fabrication d'une antenne à micro-ondes pour applications percutanées d'hyperthermie aiguë, du type coaxial monopôle ou dipôle, comprenant un piège, généralement appelé étranglement, destiné à bloquer la propagation de l'onde de retour vers le générateur. La miniaturisation du dispositif permet de l'utiliser pour des applications effractives minimales d'hyperthermie interstitielle en médecine et en chirurgie, en particulier pour l'oncologie. Selon le procédé de fabrication de cette antenne, une aiguille métallique (1) permet l'introduction de l'antenne (2, 3, 4) dans le tissu cible. Sur le conducteur externe (4) de l'antenne (2), une bague métallique (6) est connectée dans une position prédéterminée ; une gaine (5) en matière plastique est appliquée pour recouvrir le conducteur externe (2) dans la partie entre l'alimentation (7) et la bague (6) ; la paroi interne de l'aiguille métallique (1) dans laquelle l'antenne est insérée sert ensuite à contenir et guider la bague (6) et la gaine (5), en particulier, la bague (6) étant en contact électrique avec la paroi interne de l'aiguille métallique (1). On obtient ainsi une antenne à étranglement de longueur variable et de diamètre miniaturisé. Un thermocouple peut être introduit à travers l'étranglement qui fait saillie directement dans la zone d'alimentation.
