  • Publication number: 20050229872
    Abstract: A system for retrofitting an internal combustion engine to use a proportion of hydrogen gas and existing fossil fuel is disclosed. The system is comprised of a source of hydrogen gas and means for delivering hydrogen gas to the combustion chamber of the engine. The engine operating parameters are adjusted and the delivery of hydrogen is controlled to provide selective introduction of hydrogen gas throughout the engine's operating cycle. The source of hydrogen gas can comprise an onboard hydrogen reformer, or hydrogen and carbon monoxide can be reformed inside the cylinder from an on board carrier of hydrogen. A single point injector placed at the intake manifold in close proximity to the engine intake valve can be used to mix the hydrogen gas to the air/fossil fuel mixture or sequential injectors can deliver hydrogen in close proximity to each engine intake valve, or directly into each cylinder.

  • Publication number: 20050212649
    Abstract: A high power resistor includes a resistance element with first and second leads extending out from the opposite ends thereof. A heat sink of dielectric material is in heat conducting relation to the resistance element. The heat conducting relationship of the resistance element and the heat sink render the resistance element capable of operating as a resistor between the temperatures of ?65° C. to +275° C. The heat sink is adhered to the resistance element and a molding compound is molded around the resistance element.

  • Publication number: 20050113189
    Abstract: A croquet wicket lighting unit to provide illumination in the vicinity of a wicket to facilitate playing the game of croquet under conditions of low illumination. Components are attached to a mounting plate 11 that straddles the wicket. The mounting plate universally and firmly attaches to any size or style of wicket by means of retaining straps 24 and friction pads 25 in combination with universal engaging slots 12. The illumination element directs an intense beam of focused light through a hole 13 in the mounting plate and onto the playing surface immediately under the wicket to clearly reveal the passage of a ball through the wicket. The illumination scheme also casts a larger area of more diffuse light on the playing surface immediately adjacent to the focus spot to reveal croquet balls resting therein and facilitate play around the wicket.

  • Publication number: 20040225347
    Abstract: An expandable stent includes a tubular structure with an outer surface positionable adjacent to a vessel wall and an inner surface facing a lumen of a body passageway. The tubular structure further includes a plurality of expansion struts, connector struts and cells. The tubular structure has a first diameter which permits intraluminal delivery of the tubular structure into the body passageway, and a second expanded and deformed diameter which is achieved upon the application of a radially, outwardly extending force. A plurality of cavities are formed in the outer surface of the stent.

  • Patent number: 5980693
    Abstract: An extended nip press apparatus is disclosed for pressing a web of paper extending therethrough. The apparatus includes a rotatable backing roll and a press shoe having a concave surface which cooperates with the backing roll. The arrangement is such that the concave surface and the backing roll define therebetween an elongated pressing section for the passage therethrough of the web. The shoe includes an upstream portion and a device for urging the upstream portion toward the backing roll. A downstream portion extends from the upstream portion, the downstream portion being resiliently disposed relative to the upstream portion. A further device selectively urges the downstream portion toward the backing roll for controlling a pressure profile applied by the shoe to the web for inhibiting delamination of the web.

  • Patent number: 5699262
    Abstract: A method and apparatus are provided for automatically processing returned video cassettes to determine that the appropriate tape cartridges are matched with the appropriate cases, to assure that the tape cartridges are fully rewound, to check the video cassettes back into inventory and then to sort the cassettes by selected entertainment categories for reshelving. A feed chute is provided for receiving the cassettes and passing them to a size sorter for detecting the sizes of the cassettes. Cassettes of inappropriate sizes are then ejected from processing and placed in an unprocessed return staging bin. Cassettes of the appropriate size are then passed through an orientation detection and orientating section in which the video cassette cases are oriented in a particular alignment for presenting to a rewind and bar code reading system. The video cassettes are then automatically checked for an appropriate match between the tape cartridges and the cases.

  • Patent number: 5003294
    Abstract: An infra-red remote personal alarm system consists of a portable transmitter unit (10) which is intended to be worn or to be manually carried by the user, and which is operable by the user at any particular location to transmit an alarm signal in an emergency and which is to be received by a central receiving station (41) so that appropriate action can be initiated in response thereto. The transmitter unit is electrically operable and includes means (15) for transmitting pulsed infra-red alarm signals which can be picked-up by an infra-red signal receiver at the location of the user, and then retransmitted as an oscillating electrical signal via direct wiring (38, 39, 40, 42, 43) to the central receiving station (41) as a warning signal indicative at location monitoring points (43, 44) of the location from which the emergency call has been made.
