  • Publication number: 20080105033
    Abstract: A gas chromatography system comprising a sample introduction device, an oven coupled to the sample introduction device and a detector coupled to the oven is disclosed. In certain examples, the oven may be configured to receive a chromatography column in a space in the oven. In some examples, the oven may be constructed and arranged to provide a substantially constant temperature to the space during an analysis stage of the gas chromatography system.

  • Publication number: 20070065172
    Abstract: In a xerographic printing apparatus, a charge device is used to apply a charge to a photoreceptor. The charge device includes a wire. A shuttle moves along the charge device, and includes a brush wherein the sides of the bristles contact the wire. When the brush moves along the wire, an accumulation of stray particles on the wire is made relatively smooth.

  • Publication number: 20070065173
    Abstract: In a xerographic printing apparatus, a charge device is used to apply a charge to a photoreceptor. The shuttle includes a wiper that cleans a sidewall of the charge device. A tab is disposed adjacent the sidewall to retain toner or dirt accumulated by the scraper. The tab is electrically insulative, and effectively covers the accumulated toner or dirt, to lower the possibility of arcing within the charge device.

  • Publication number: 20060180466
    Abstract: The invention relates to an electrochemical sensor and method for providing the sensor having an insulator, an electrode deposited on the insulator, an electrolytic material in contact with the electrode for providing an electrical connection, and a cooling and heating element in contact with the insulator and spaced apart from the electrode for adjusting a temperature of the sensor.

  • Publication number: 20050053397
    Abstract: A charging system for uniform charging of charge retentive surfaces such as photoreceptors in imaging systems. The charging system includes corona producing elements and grid elements such as scorotron screens wherein the grid elements are arranged generally parallel to each other and have differentiated grid feature patterns. The differentiated grid feature patterns enable more uniform charging.

  • Publication number: 20040206285
    Abstract: An electromechanically actuated outrigger assembly includes a main body having a bearing point. An outrigger support is to be connected to an outrigger boom. The support is pivotally connected to the main body at the bearing point. An electrical actuator is connected to the main body and has a movable piston. A lever assembly operatively connects the outrigger support to the piston to pivot the outrigger support about the bearing point when the piston moves. The lever assembly has a piston connection point offset vertically and laterally from the bearing point and is connected to the piston at the piston connection point, preferably, in a pivotal connection.

  • Publication number: 20040096539
    Abstract: An apparatus for molding an optical lens from a molten thermoplastic resin material using an injection molding machine, and including means for forming a mold cavity defined by a pair of opposed, spaced apart inserts shaped and configured to define opposite faces of said optical lens and having a plurality of overflow wells surrounding the mold cavity means for injecting a predetermined optimum volume of resin material into said mold cavity; means for controllably moving at least one insert relative to the other insert, wherein such relative insert motion is driven by a power cylinder capable of providing a variable compression stroke during molding and is initiated prior to completion of said injection; means for controlling the velocity and/or compressive force of the compression stroke of said power cylinder such that said compression is conducted at a first selected relatively high velocity, thus urging excess resin from said cavity into said overflow wells after which the compression force is varied to a

  • Patent number: 5835346
    Abstract: A low profile personal computer includes an enclosure having a bottom wall. A riser card including functional circuitry extends vertically from the bottom wall and partitions the enclosure into first and second regions. A motherboard is positioned within the first region of the enclosure along the bottom wall and adjacent to the riser card for interfacing with the riser card. A series of horizontal option card interfaces are located above each other on the riser card within the first region of the enclosure each for interfacing with a corresponding option card and to position the option cards horizontally over the motherboard. The horizontal option card interfaces are capable of interfacing with a maximum of three option cards at the same time. The functional circuitry on the riser card minimizes the number of option cards which enables the overall height of the enclosure to be minimized.

  • Patent number: 5820171
    Abstract: A filler plate for filling an option card slot in a computer enclosure includes a cover plate portion for substantially covering the option card slot. The cover plate portion has a first end and a second end opposite to the first end. A tongue extends from the first end of the cover plate portion for insertion into a capture slot located in the enclosure adjacent to the option card slot to secure the first end of the cover plate portion to the enclosure. First and second retaining tabs extend substantially perpendicularly from the cover plate for engaging first and second edges of the option card slot to hold the filler plate in position relative to the option card slot.

  • Patent number: 5781417
    Abstract: A circuit board retainer for use within an enclosure for guiding and securing a circuit board within the enclosure includes a guide portion having an upper rail and a lower rail extending along an edge of the circuit board retainer forming a slot therebetween for guiding a side of the circuit board. A latching portion positioned adjacent to the guide portion engages an ejector lever pivotably connected to the circuit board. The ejector lever is capable of locking the circuit board in place relative to the circuit board retainer.
