  • Patent number: 6472850
    Abstract: A method for dynamically determining tap position in a step voltage regulator is disclosed. A present tap position is determined and the value of an applied voltage across a tap changing mechanism is measured. Based upon the value of the applied voltage, a directional change in the tap position is detected. A trigger signal is also generated which is responsive to a detected change in tap position. Finally, a new tap position is calculated based upon the present tap position and the directional change in the tap position, when the trigger signal indicates that a change in tap position has taken place.

  • Publication number: 20020145517
    Abstract: A circuit monitoring system for performing synchronized waveform capture. A waveform capture trigger communication network interconnects a plurality of monitoring devices. The system provides direct device to device trigger communication between monitoring devices in a synchronized group. Power system waveform data is stored in the monitoring device memory of all members of the synchronized group in response to a trigger event initiated by any monitoring device in the synchronized group. High speed trigger communication results in substantially simultaneous waveform capture among the members of the synchronized group.

  • Patent number: 6262346
    Abstract: A method of modifying ethylene biosynthesis in a plant comprises inserting into the genome of the said plant a DNA sequence such as SEQ-ID-NO-1 (encoding 1-aminocyclopropane-1-carboxylic acid synthase (ACS)) and/or sequence SEQ-ID-NO-2 (encoding an ethylene-forming enzyme (EFE)) which modifies the activity of at least one of ACS or EFE. The method may be used to modify fruit ripening characteristics, especially in bananas.

  • Publication number: 20010000355
    Abstract: A trip unit is provided with non-volatile memory, such as EEPROM (Electrically Erasable Programmable Read Only Memory) or Flash memory, for storing the firmware, including initializing parameters, boot code, and operational parameters. This configuration enables one to change the trip unit's firmware after it is manufactured. The present invention provides thus increased functionality to trip units by enabling upgrades and servicing of the trip unit by downloading replacement firmware to it. This would include remotely downloading firmware when the electronic trip unit is connected to a host controller, such as a multi-purpose computer either directly, over the telephone lines, LAN or any other suitable connection such as the Internet.

  • Patent number: 6127654
    Abstract: A heating apparatus and method of making such apparatus has a deposited heating element of oxidized metal powder. The metal powder is oxidized more than forty percent and preferably between sixty and ninety-five percent. The oxidation is the deposited metal powder is increased by either modifying the powder or the modifying the deposition process. The powder is modified by preoxidation, reducing the size of particles, removing oxidation inhibitors, adding oxidation catalysts and enhancers and increasing the surface area of the particles. The process of deposition is modified by using more oxygen and using a high velocity oxy-fuel plasma deposition process.

  • Patent number: 6058978
    Abstract: A method and apparatus for relining, repairing or reconstructing existing infrastructure pipeline systems that are new, structurally deficient or experiencing an excessive amount of exfiltration or infiltration, or converting new or damaged pipelines into dual-containment pipelines. A plurality of stock, high density polyethylene lining pipes having a cylindrical cross-section with a diameter up to 36 inches and lengths of 40-50 feet are joined together to a job specific length. The lining pipe is then heated to its flex temperature and gradually deformed to a reduced diameter. At the job site, the deformed lining pipe is inserted into the existing pipe and a controlled, pressurized environment is created therein for a period of time dependent on the pipe's length. Pressurized steam is first inserted to provide heat and internal pressure to expand the pipe. Then, compressed air is inserted to cool the pipe while maintaining the internal pressure to complete the expansion and set the pipe.

  • Patent number: 5891698
    Abstract: The invention relates to humanized milk. The milk is produced by a non-human transgenic mammal wherein the genome of said transgenic non-human mammal contains at least one heterologous gene encoding for a human catalytic entity and wherein the catalytic entity produces oligosaccharides and glycoconjugates that are present in the milk of said transgenic non-human mammal. An especially useful catalytic entity is human glycosyltransferases which produce oligosaccharides and glyconjugates. Specifically exemplified, is the production of 2'-fucosyl-lactose in the milk of transgenic mice which contain and express a transgene encoding .alpha.-1,2-fucosyltransferase operatively linked to a mammary gland specific promoter. A method of obtaining humanized milk is disclosed.

  • Patent number: 5892070
    Abstract: The invention relates to transgenic non-human mammals characterized in that the genome of said mammals contain at least one heterologous gene encoding for the production of heterologous catalytic entity selected from the group consisting of enzymes and antibodies, and wherein said catalytic entity produces a second heterologous product in the milk of said mammal. Especially useful in the practice of the invention are human glycosyltransferases and transgenic sheep, goats and cows. The heterologous product includes oligosaccharides and glycoconjugates. Specifically exemplified, is the production of 2'-fucosyl-lactose in the milk of transgenic mice which contain and express a transgene encoding .alpha.-1,2-fucosyltransferase operatively linked to a mammary gland specific promoter.

  • Patent number: 5750176
    Abstract: The invention relates to the milk of a transgenic non-human mammal. The milk is characterized in that it contains heterologous components produced as the secondary gene products of a heterologous gene contained in the genome of the transgenic non-human mammal. The heterologous gene encodes a heterologous catalytic entity such as a human enzyme selected from the group consisting of glycosyltransferases, phosphorylases, hydroxylases, peptidases and sulfotransferases. Especially useful in the practice of the invention are human glycosyltransferases. The desired heterologous components include oligosaccahrides, glycoconjugates. Specifically exemplified, is the production of 2'-fucosyl-lactose in the milk of transgenic mice which contain and express a transgene encoding .alpha.-1,2-fucosyltransferase operatively linked to a mammary gland specific promoter.

  • Patent number: 5087428
    Abstract: A closed container has openings at an input end for drawing air into the container and openings at the output end for passing air out of the container. An ozone generator is disposed inside the container adjacent the input end and a corona generator is disposed in the container adjacent the output end. The corona generator includes a dielectric made of a material having a dielectric constant of 1000 or greater. Impure air which is drawn in at the input end passes over the ozone generator whereby the ozone reacts with the impurities of the impure air to provide purified air. The purified air with remaining ozone is passed over the corona generator means to destroy the remaining ozone.
