Abstract: A separable loadbreak connector cuff venting tool having a handle formed of an electrical insulator material. An electrically insulating head is fixed on the handle's forward end. Two or more wedges, sized and shaped for slidable insertion within the cuff, are formed on the head. A rearwardly directed force applied along the handle's longitudinal axis gradually slides the wedges within the cuff, thereby venting partial vacua from within the cuff to the surrounding atmosphere and reducing the likelihood of flashover. Optionally, a clamp may be provided on a rearward portion of the handle for use in clamping the tool's handle to a hotstick handle. As another option, a pivot fulcrum may be provided on the rearward portion of the tool's handle for use in pivotally levering the tool's handle away from the hotstick handle. The tool's head, clamp and pivot fulcrum extend transversely away from the cuff venting tool, in the same direction.

Title: Neutral amino acid transporter and gene thereof
Inventor: KANAI YOSHIKATSU
IPC: A61K48/00
Filed: 1999-09-03
Abstract: A novel amino acid transporter molecule mediating transportation of amino acids, which are nutrients essentially required in the survival and proliferation of various normal cells constituting a living body and various pathology-associated abnormal cells such as tumor cells, into cells and being expressed specifically in tumor cells compared with normal cells; and drugs for treating various pathogenic conditions such as tumor (cancer) which are obtained by identifying and isolating the above amino acid transporter molecule and identifying a substance capable of inhibiting the biological activity and/or expression of this molecule. Intensive studies were made to identify a tumor cell membrane surface molecule associating or interacting with a cell membrane surface 4F2hc molecule seemingly playing an important role in the activation of an unknown amino acid transporter. As a result, a gene encoding the novel amino acid transporter molecule, which mediates the incorporation of various neutral amino acids, various drugs or physiological substances into cells, has been found out and a substance capable of inhibiting the incorporation of amino acids via this molecule and thus inhibiting the proliferation of tumor cells has been also found out.

Title: High power density combined cycle power plant system and method
Inventor: ROLLINS WILLIAM SCOTT III
IPC: F01K23/10
Filed: 1999-08-24
Abstract: A process is disclosed for increasing the specific output of a combined cycle power plant and providing flexibility in the power plant rating, both without a commensurate increase in the plant heat rate. Thermal efficiencies of combined cycles may be upgraded through the strategic use of additional fuel and/or heat input. In particular, gas turbines that exhaust into heat recovery steam generators, can be supplementally fired to obtain much higher steam turbine outputs and greater overall plant ratings, but without a significant penalty on efficiency.
Patent CA-2344564-A1 (CA)
Inventor: SNOPEK DAVID A
IPC: H02K3/04
Filed: 2001-05-03
Abstract: There is disclosed a groundwall insulation system for use in dynamoelectric machines carrying voltages above 4 kV and preferably in the order of 13.8 kV, or higher. The groundwall insulation comprises two layers of insulation wound onto the conductors of the high voltage winding. The first layer of insulation has a first permittivity that is greater then the permittivity of the second layer of insulation wound onto the first layer of insulation. As a consequence, at the juncture between the first and second layers there is a sharp increase in the electric field profile as seen through the groundwall insulation. This step increase in the electric field profile results in the electric field adjacent the conductor having a maximum magnitude that is less than that normally experienced by insulation systems in the past. By reducing the maximum magnitude of the local electric field profile within the groundwall insulation the life of the insulation and hence the electrical conductor is improved while at the same time permitting a reduction in the thickness of the groundwall insulation.
Patent CA-2345845-A1 (CA)
Title: Bitline precharge
Inventor: MA PETER P
IPC: G11C7/18
Filed: 2001-04-30
Abstract: An architecture and method for fast precharge of bitlines in a densely packed, dynamic content addressable memory is disclosed. The dynamic content addressable memory cells are arranged according to an open bitline architecture to obtain high packing density. The bitlines are precharged through equalization between every two adjacent open bitline pairs. More specifically, a bitline and its adjacent neighbouring bitline on the same side of the bitline sense amplifiers are equalized at several locations along the bitlines such that they are equalized at high speed, which is typically not available in open bitline architectures. Hence the adjacent bitlines are precharged in a manner similar to a folded bitline architecture. Additional equalization circuits are connected between the complementary bitlines of each open bitline pair, therefore during the precharge phase, all four bitlines of the two open bitline pairs are equalized with each other. To ensure that all four bitlines equalize to the midpoint voltage level, complementary logic levels are written to the bitlines prior to equalization.

Abstract: A mid and high frequency transducer having a compact magnet system. A first seat has an annular wall that retains a first disk shaped magnet therein and an annular channel is defined therebetween. A second scat rests on top of the first magnet and first seat and is connected thereto but does not occlude the annular opening.

Title: Method for displaying information on multiple display devices
Inventor: BISKEY BRUCE L
IPC: G09G5/12
Filed: 1998-09-01
Abstract: Video adapter hardware and software permitting the display of computer information and television signals across several display devices. The video adapter hardware includes two graphics user interface accelerators, two television tuners, one or more video decoders, and one or more video multiplexes. Each accelerator is coupled to a memory unit for access to graphics data. One television tuner accepts input from an outside television source, such as a cable television company or a video cassette recorder. In addition, the video multiplexers accept input from other external video sources. Video data is output from the graphics accelerators to multiple screens. Video adapter software displays a toot window allowing the user to select first input for the first display device and a second input for the second display device. The software displays the results of the two inputs on the respective display devices. If the inputs are identical, however, the information may be displayed across both display devices.

Filed: 1999-11-12
Abstract: Cette invention a trait à un capteur pourvu d'une substance active de détection soumise à la substance à détecter et une substance active de référence protégée de la substance à détecter. Le dispositif comporte des thermocouples possédant un ensemble de jonctions à proximité de la substance active de détection ainsi qu'un autre ensemble de jonctions à proximité de la substance active de référence, ces thermocouples étant destinés à la mesure des températures de ces substances respectives. Ces jonctions, qui sont connectées de manière différentielle, permettent de mesurer une différence entre deux températures. Un générateur de chaleur, commun aux deux substances, se trouve à proximité de celles-ci. Il est possible d'appliquer des vagues thermiques à ces substances par le biais du générateur de chaleur, les températures résultantes étant ensuite mesurées. Si des facteurs environnementaux ou certaines substances exercent une influence sur la substance active de détection, la réponse thermique de celle-ci sera différente de celle de la substance active de référence et une indication différentielle du type impulsion sera détectée. Cette indication présentera certaines caractéristiques d'amplitude, de forme et de durée, ce qui permet une identification du type de la substance détectée par le capteur et de sa concentration.
