  • Patent number: 8611793
    Abstract: Apparatus for electrically reconditioning a rotatable photoreceptor in an electrophotographic (EP) printer includes a charger, an exposure subsystem, a transfer station, and an erase lamp arranged in that order around the photoreceptor in the direction of rotation thereof. A first corona electrode is disposed within 3 cm of the surface of the photoreceptor, but not in contact therewith, between the transfer station and the erase lamp. The transfer station and the erase lamp are at most 1 cm apart. A second corona electrode is disposed within 3 cm of the surface of the photoreceptor, but not in contact therewith, after the erase lamp in the direction of rotation of the photoreceptor. The erase lamp and the second corona electrode are less than 1 cm apart.

  • Patent number: 8606148
    Abstract: An electrophotographic photoreceptor is prepared for charging. Corona electrodes before and after the erase lamp apply respective biases to provide the correct sign of charge for cleaning, and to discharged trapped charges in the photoreceptor. Toner is then cleaned off the photoreceptor. This leaves the photoreceptor electrically and mechanically reconditioned and ready for its next printing cycle.

  • Publication number: 20130281170
    Abstract: A wagering game is played on processor-based gaming apparatus including: providing a gaming apparatus of processor, video display and gaming input system; after a wager, the processor executes code to play a first wagering game and display images associated with the first wagering game on the video display; when the processor recognizes a predefined trigger outcome, bonus play of a second game different from the first wagering game begins; the processor identifies bonus points accumulated during bonus play distinct from any wagering credits; the processor displays at least two distinct bonus events of a first bonus event played on the first wagering game and a second bonus event played on the first wagering game. The first bonus event and the second bonus event being activated by the processor diminishing accumulated bonus points. An amount of bonus points needed to activate the first bonus event is different from an amount of points needed to activate the second bonus event.

  • Patent number: 8020585
    Abstract: A leak detection system for detecting a leak within a duplex valve assembly is disclosed. The duplex valve assembly includes a first valve, a second valve and an intermediate fluid flow passageway fluidly interconnecting the first valve to the second valve. The leak detection system includes a means for indicating whether the first valve is maintained in a closed position or an open position, a means for indicating whether the second valve is maintained in a closed position or an open position, and a pressure change detector within the intermediate fluid flow passageway. The pressure change sensing means is at least partially positioned within the intermediate fluid flow passageway for detecting a pressure change within the intermediate fluid flow passageway.

  • Publication number: 20100174351
    Abstract: Biocompatible materials for use in vascular applications or for implantation have been engineered, combining human recombinant tropoelastin with other synthetic or natural biomaterials to form protoelastin. The materials can be in the form of elastin films on metal or polymer substrates, laminates of alternating polymer and elastin, blends of polymer and elastin, or elastin crosslinked with or tethered to polymer or metal. These are mechanically stable, elastic, strong and biocompatible (i.e., not thrombogenic and promoting adhesion of cells, especially human endothelial cells), not eliciting a foreign body response. Plasma polymerization of substrate is shown to enhance biocompatibility, especially when used to bind elastin or other protein to the substrate.

  • Patent number: 7700126
    Abstract: Biocompatible materials suitable for use in vascular applications have been engineered, combining human recombinant tropoelastin with other synthetic or natural biomaterials to form protoelastin. The materials can be in the form of elastin films on metal, bone, ceramic or polymer substrates, laminates of alternating polymer and elastin, blends of polymer and elastin, or elastin crosslinked with or tethered to polymer. The flexibility in engineering and design makes protoelastin biomaterials suited not only to the production of conduits but any number of other vascular applications that require blood contacting surfaces. Tropoelastin and the subsequently engineered biomaterial protoelastin provide the opportunity to satisfy a large unmet need for a biocompatible material adaptable enough to meet a range of diverse vascular uses. These are mechanically stable, elastic, strong and biocompatible (i.e., not thrombogenic and promoting adhesion of cells, especially human endothelial cells.

  • Patent number: 7621302
    Abstract: In a system including a gas source, a target cylinder for receiving gas, a conduit for carrying gas, and a valve for controlling the flow of gas, a method of dosing the target cylinder with gas is disclosed. The method comprises the step of calculating a mass flow rate for dosing the conduit and the target cylinder. The valve is biased to an open position to permit gas to flow through the conduit and into the target cylinder. The mass flow rate and the cumulative mass of gas flowing through the conduit are measured using a mass flow meter. The valve is biased to maintain the measured mass flow rate of gas flowing through the conduit substantially equivalent to the calculated mass flow rate. The valve is biased to a closed position once the measured cumulative mass of gas is substantially equivalent to the pre-determined mass of gas.

  • Publication number: 20070157517
    Abstract: Hydrogen generating method and apparatus. The apparatus comprises a mixed phase protonic-electron conducting cermet membrane (2), wherein said membrane is coated with porous metal or composite catalyst (1) effective to decompose hydro-carbon and water reactants into a hydrogen-rich syngas at elevated temperature and pressure. The hydrogen ions are continuously withdrawn in situ by diffusing them through the mixed phase conducting cermet membrane (2) to the second membrane side where the hydrogen ions can be reconstituted into molecular hydrogen with a supply of electrons. The method favorably shifts the equilibrium of steam reforming and water gas shift reaction by use a single stage, high efficiency and high purity membrane reactor.
