Title: Data driving circuit for lcd display
Inventor: LEE SYWE NENG
IPC: H04N5/66
Filed: 1993-10-25
Granted: 2002-12-31
Abstract: A data driver circuit and system driving scheme that can be integrated directly onto an LCD display substrate to eliminate the cost of the peripheral integrated circuits and the hybrid assembly needed by unscanned active matrix liquid crystal displays to con-nect them to the array. A demultiplexer circuit is deposited on the display for demultiplexing a group of Y columns of multiplexed video data input signals to X groups of Y pixel capacitors that are also deposited on the substrate in Z rows. In addition, a precharg-ing circuit is deposited on the substrate to precharge the pixel capa-citors to a first voltage level such that the video data input signals coupled thereto in a demultiplexed fashion causes the pixels to dis-charge to a second predetermined voltage level to provide a video display as the rows of pixels are sequentially scanned.

Title: A system for taking backup in a data base
Inventor: LARSSON BO ERIK STEFAN
IPC: G06F11/14
Filed: 1993-12-03
Granted: 2001-10-16
Abstract: For backing up in a distributed real time data base on primary memory in operation, all data in the data base are structured as belonging to one of several logic data bases, a logic data base being able to, but need not extend over several processors. A backup function of a certain logic data base is activated by sending a message to a central backup handler, which has information regarding processors, over which the current backup system extends, and synchronizes the backup function over processor borders. The synchronization includes that local data base handlers are informed that backup will be started and that a new transaction log is being created, in which all transactions having not attained commit state and which shall therefore not be included in the backup are logged. The backup will thereafter only contain changes of transactions in the old transaction log.

Title: Switching type electrical receptacles having selectively orientable plug-receiving contact carriers
Inventor: SCHLESSINGER MARC A
IPC: H01R25/00
Filed: 1995-11-29
Granted: 1999-05-18
Abstract: An electrical receptacle includes a nonconductive con-tact carrier that mounts a set of female electrical contacts that are configured to receive and conductively engage plural conduc-tive prongs of a male plug.  The carrier has a generally cylin-drical outer wall that is received within a generally cylindrical chamber that is defined by a nonconductive housing.  The housing mounts the carrier for rotation about a center axis that extends centrally through the chamber.  When the carrier is rotated about the center axis relative to the housing to an "on" position (that resides within a relatively wide angular range of  "on" posi-tions), housing-carried electrical contacts that extend through housing-defined passages engage carrier-carried electrical con-tacts that extend through carrier-defined passages.   When the carrier is rotated about the center axis relative to the housing to an "off" position, electrical connection is interrupted be-tween selected pairs of the housing-carried and carrier-carried contacts.  A detent preferably is interposed between the carrier and the housing for releasably retaining the rotatable carrier in its "off" position.  The rotatability of the carrier while remai-ning within its range of "on" positions permits a male electrical plug (and an appliance cord or other form of electrical wire that is attached to the plug) to be oriented as desired relative to the receptacle for such purposes as minimizing wear and tear, and/or to accommodate the positioning of furniture at locations near where the receptacle is installed.

Title: Power steering fluid reservoir
Inventor: MANCELL MICHAEL G
IPC: B01D35/027
Filed: 1996-04-03
Granted: 2001-07-10
Abstract: This invention relates to an improved reservoir for power steering fluid which is particularly suitable for use on large vehicles, such as trucks. The improved reservoir of this invention comprises a well to contain a surplus of power steering fluid. The well has an inlet to permit the introduction of fluid from a power steering mechanism into the well, and an outlet to permit the fluid to flow out of the well to the power steering mechanism. The well also has a filter attached over the inlet. The filter comprises a container having a lower chamber, a side chamber, a filter medium and a relief valve. Fluid received in the lower chamber from the inlet pipe flows to the side chamber and through the filter medium from the outside surface to the inside surface, and then out through a centre orifice to the well. Fluid at or above a predetermined pressure flows through the pressure relief valve and out through the centre orifice to the well.

Abstract: Procédés et compositions permettant de mesurer la longueur d'un télomère, trouvant une application dans des techniques médicales diagnostiques, pronostiques et thérapeutiques. Ces procédés de mesure incluent des procédés basés sur l'extension d'amorces et des procédés basés sur des sondes. Les premiers impliquent l'élongation d'amorces télomèriques, de liaison et/ou subtélomèriques dans des conditions telles que le télomère serve de matrice à l'extension de l'amorce et que les produits de l'extension de l'amorce ainsi obtenus puissent être comparés à des étalons de longueur connue pour donner une mesure de la longueur du télomère. Les procédés basés sur des sondes permettent de mesurer la longueur d'un télomère à l'aide d'ADN provenant de cellules lysées ou entières, et consistent à hybrider une partie excédentaire de sonde avec toutes les séquences de répétition télomériques présentes dans le télomère, à mesurer la quantité de sonde liée et à corréler ladite quantité de sonde liée mesurée avec la longueur du télomère.

Title: Method and apparatus for steam pasteurization of meat
Inventor: O'CONNOR JERRY
IPC: A23B4/00
Filed: 1995-11-06
Granted: 2001-01-09
Abstract: An apparatus for destroying pathogens on meat includes a dewatering station (18), a steam heating chamber (32), and a cooling chamber (40). The meat is treated as it is moved along by a conveyor (25). The dewatering chamber includes an air blower with nozzles for blowing air at the surface of the meat to remove surface water from the meat. The steam heating chamber is disposed adjacent the dewatering chamber and includes a steam heating chamber enclosure that is sealed for maintaining a positive pressure in the steam heating chamber relative to the dewatering chamber. In one embodiment the steam chamber moves along with the meat on the conveyor. The cooling chamber is disposed adjacent the steam chamber opposite from the dewatering station. The cooling chamber has nozzles for spraying chilled water onto the surface of the meat for rapidly cooling the meat after it is passed through the steam heating chamber. The meat conveyor extends through the dewatering chamber, the steam chamber, and the chilled water chamber. The meat conveyor supports the meat and transfers it from chamber to chamber. A method for destroying pathogens on meat is also disclosed that includes the steps of removing surface water from the meat, passing the meat through a steam chamber having a positive pressure relative to the outside of the steam chamber, and rapidly chilling the surface of the meat.

Abstract: A multiple trepan boring device (D, D') for producing substantially large cu ts (C) in large works (W), such as concrete dams, comprises a drilling shaft (2 4) adapted to be translationally displaced along its longitudinal axis and carrying a series of spaced apart cylindrical rotatable trepans (30) each having a peripheral cutting surface (32) and an annular cutting surface (34, 69), the latter extending in plane perpendicular to the axis of the drilling shaft (24) and radially between the shaft (24) and the peripheral cutting surface (32). Weights (40) apply continuous downwards forces on the shaft (2 4) and thus on the trepans (30). With the trepans (30) resting on the top of th e work (W) to be cut, the trepans (30) are rotated in place, and under the aforementioned forces the peripheral cutting surface (32) of each trepan (30 ) bores a hole until the drilling shaft (24) rests on the top of the work (W). Then the shaft (24) is displaced translationally while the trepans (30) continue to rotate thereby causing the annular cutting surfaces (34, 69) to remove a layer of the work (W) extending between the shaft (24) and the peripheral cutting surface (32). This procedure is repeated so as to produce a cut (C) of a width corresponding to the outside diameter of the trepans (30) by successive removal of crescent-shaped layers from the work (W). After the removal of each layer, the shaft (24) is lowered along a distance corresponding to the difference in radii between the drilling shaft (24) and the trepans (30).
