  • Patent number: 8459778
    Abstract: Improved output quality of a printer used in UV curable ink jet printing is achieved by minimizing or eliminating a print artifact referred to as gloss banding or tire tracking. A same or a similar number of nozzles as used in conventional printers is used to achieve a desired throughput, but the nozzles are arranged so that any given square inch of substrate to which ink is being applied receives a lower amount of ink. A longer effective print head is provided by arranging the print heads into a longer array, where the print heads are butted substantially end-to-end. As a result, the net throughput of the printer is the same as that of a conventional printer because the printer uses the same number of print heads, but the amount of ink that is applied to any given square inch is less on a pass.

  • Publication number: 20130127936
    Abstract: Systems and methods of automatically bleeding air from a primary ink delivery system, so little or no air is mixed with the ink once it reaches a secondary ink system containing print heads. An air bleeder return assembly with a flow restrictor orifice that is configured to remove air from ink pumped to the carriage of print heads, thereby minimizing jet dropouts. Additionally, this setup provides the added advantage of the ability to run the bulk bags dry without ingesting large quantities of air to the ink delivery system.

  • Publication number: 20130050368
    Abstract: Gloss is controlled in UV ink jet printing within a printing system. Controlled pinning energy is used to adjust the amount of ink interaction between drops, substrate, and ink layers, resulting in virtual elimination of gloss banding and control of the finished gloss level from a gloss level of approximately 85 to a gloss level of approximately 5.

  • Patent number: 8237366
    Abstract: An output window for a vacuum electron device comprises an output waveguide, an intermediate layer of dielectric material joined to the interior of the output waveguide with a vacuum-tight seal, and upper and lower layers of dielectric material spaced apart from the intermediate layer and arranged above and below, respectively, the intermediate layer in a vertical orientation of the output waveguide. The upper and lower layers including openings. Supports extend inwardly into the output waveguide and support the upper and lower layers. Pillars extend through the openings in the lower layer and support the intermediate layer. The openings in the upper and lower layers permit a venting of a region between the upper layer and the intermediate layer and a region between the lower layer and the intermediate layer during the sealing of the intermediate layer while the intermediate layer is supported by the pillars.

  • Patent number: 8142731
    Abstract: A device for providing a relatively constant rate of dissolution of a solid article (2) within it has one or more opening (22) to allow the passage of water. There is a flow pathway between said one or more openings and the solid article, which flow pathway is obturated by a water-permeable packing (26), through which water must pass, in entering or leaving the device.

  • Publication number: 20110041882
    Abstract: A device for cleaning a surface comprises a pressurised container containing a cleaning composition; a nozzle through which the composition is arranged to be dispensed, in use, upon an actuation of a valve; a shroud attached to the container and surrounding the nozzle. The shroud has a hollow generally cylindrical portion adjacent to the nozzle for guiding the dispensed product in the direction in which it leaves the nozzle, and a flared portion at the end of the cylindrical portion furthest from the nozzle forming a spreading plate for guiding the dispensed product laterally when in contact, in use, with a surface to be cleaned. The nozzle is arranged to be actuated by movement of the container towards the shroud. The device comprises a reservoir. The nozzle and shroud are configured so that, in use, the cleaning composition is directed across the surface to be cleaned and into the reservoir.
