Filed: 2000-05-10
Abstract: A repair bladder manufactured to meet the demands of small pipe rehabilitation.        The said bladder will be flexible as to navigate through clean-outs as well as 45 degree elbows and 90 degree elbows. The said bladder will still be able to stay firm enough to be able to be launched through clean-outs and pushed into place and keep its shape.      The bladder should also be of a flow-through design as to allow water to pass through. The bladder will also be made of a material that will not stick to cured resin. This bladder will also be reusable. The bladder will be made of gum rubber so as to allow the bladder to pull away from the repair.        The bladder will consist of two end caps made of aluminum or other light material. These caps will be joined by a non-stretching hose which will allow liquids to pass through. The extruded rubber sleeve is positioned over these ends and fastened. Air fittings are attached and harness receiving ends are attached.

Title: Method and apparatus for increasing the rating of a transformer
Inventor: OWEN DONALD W
IPC: H01F27/04
Filed: 2000-05-11
Abstract: The voltage class rating of a transformer is increased by increasing the rating of an off the shelf molded transformer bushing. The rating is increased by increasing the distance from the non-insulated portion of a conductor of a transformer bushing and the transformer wall is increased. A conductive extension is connected to the conductor. Insulating material in the form of mastic and heat shrink tubing is applied to the external portion of the conductor and extension. When the modified transformer bushing is installed into a transformer, an internal end of the conductor extends below the surface of the oil in the transformer. The level of the oil also covers an internal insulating shoulder of the bushing. The insulating values of the mastic and heat shrink tubbing and the insulating value of the conductor immersed in oil, combine to increase the voltage class rating of an off the shelf molded transformer bushing and thereby the transformer.

Title: Method for manufacturing ink jet recording head, ink jet recording head manufactured by such method, and laser working method
Inventor: KOIDE JUN
IPC: B23K26/06
Filed: 2000-06-29
Abstract: A method for manufacturing an ink jet recording head in which an ink discharge port for discharging an ink droplet to be adhered to a recording medium, a liquid chamber for containing ink to be supplied to the ink discharge port, an ink low path for communicating the ink discharge port with the liquid chamber, an energy generating element provided in the ink flow path and adapted to generate energy for discharging the ink and an ink supply opening for supplying the ink from exterior into the liquid chamber are formed by bonding or adhering plate members. In the method when an orifice plate in which the ink discharge port is formed is subjected to laser working, a laser light of plural pulses having very great spatial and time energy density and emitted from a laser oscillator for oscillating the laser light at a pulse emitting time smaller than 1 pico-second is used, and the laser beam is illuminated from an outer surface side of the orifice plate which is opposite to an ink supplying side thereby to form an ink discharge port working pattern on the outer surface of the orifice plate by focus projection.

Abstract: A multi-variable work assignment process is used to assign work items, such as voice calls, e-mails and other communications or tasks, to agents in a call venter. The multi-variable work assignment process determines whether values of a particular variable characterizing the work items fall within a designated range, and if so utilizes at least one additional variable for making the work assignment decision. The work assignment process may also or alternatively consider a weighted combination of multiple variables in making the work assignment decision. Examples of variables which may be used in the multi-variable assignment process include current wait time, service objectives skill preference, skill level, anticipated wait time, predicted wait time, etc. The invention may be implemented in a one-to-many work assignment process which selects one of a set of agents available for handling a particular work item, in a many-to-one work assignment process which selects one of a set of work items for handling by a particular available agent, or in a many-to-many work assignment process in which multiple agents are each considered simultaneously for handling multiple work items.

Abstract: A disclosed battery powered security monitoring system provides a security system that monitors validation signals detected by a sensor at least twice during each oscillation of the validation signal. This technique may be applied both while the main power to the gaming machine is on and while a backup power source (e.g., a battery) is on. Preferably, the security system of this invention employs a custom integrated circuit (e.g., an end-user programmed complex programmable logic device) to perform some the security functions such as supplying the validation signal to the sensor and comparing a sensor output signal to the validation signal to determine whether access to a gaming machine device has occurred.

Title: Traitement de minerais de sulfure de cuivre
Inventor: RICHMOND GEOFFREY DOUGLAS
IPC: C22B15/00
Filed: 1999-07-14
Abstract: Cette invention se rapporte à un procédé qui permet d'extraire le cuivre contenu dans une charge minérale renfermant un minerai de sulfure de cuivre (1) et qui consiste à cet effet à broyer et à mélanger la charge (2, 6, 10) puis à lessiver la charge dans un autoclave (20). Les conditions de l'autoclave sont contrôlées pour que la présence d'oxygène à une pression suratmosphérique maintienne le rapport entre les ions ferreux et les ions ferriques à un niveau propre à faciliter le lessivage du cuivre de la charge. Le lessivage est effectué en présence d'acide pouvant être lui-même généré par des conditions d'oxydation dans l'autoclave. Un lessivage ultérieur est effectué dans une série de cuves (22, 24, 26 et 28), puis les particules solides sont séparées de la solution dans une série d'étapes, tel qu'un traitement dans un hydroclassificateur (30), dans un clarificateur (32) et dans un filtre de polissage (38). Le cuivre est extrait du produit de lessivation résultant au niveau d'un poste d'extraction de cuivre (44), le produit final à base de cuivre (54) étant récupéré dans des cellules d'électroextraction (52).

Abstract: An ultrasonic probe includes a piezoelectric element for transmitting and receiving ultrasonic waves and an acoustic lens provided on an ultrasonic transmission/reception side of the piezoelectric element.   The acoustic lens is formed in an acoustic lens shape by vulcanization formation through addition of 2,5-dimethyl-2,5-di-t-butyl peroxy hexane as a vulcanizing agent to a composition prepared by addition of silica (SiO2) particles in an amount of 40 wt% to 50 wt% to silicone rubber with a dimethylpolysiloxane structure including vinyl groups. Thus, the ultrasonic transmission and reception sensitivity is improved and the degradation in frequency characteristics is diminished. Consequently, higher resolution of an ultrasonic image and higher sensitivity can be achieved.

Abstract: A group operated circuit disconnect apparatus for overhead electrical power lines includes an operator controlling a plurality of disconnect switches.  Each disconnect switch includes a vacuum circuit interrupter mounted inside an insulating bushing. Current is transferred from a terminal pad through the vacuum circuit interrupter to a vacuum terminal pad by attaching a silver-plated contact nut to a movable contact end of the vacuum circuit interrupter and using a rocker type contact assembly to connect the contact nut to the vacuum terminal pad. A rotating insulator of the disconnect switch drives a make/break mechanism that opens and closes the contacts inside the vacuum circuit interrupter. The rotating insulator turns a frame assembly so that an appropriate point in operation a trip point is reached and springs quickly rotate an actuator assembly driving the movable vacuum contacts at a high speed to the open or close position. The contact speed is approximately 7-10 milliseconds, which provides efficient circuit interruption or closure.
