Abstract: A mask fixture for etching an item includes: a top fixture disposed over the item, including a reservoir centered within the top fixture for containing an etchant; a bottom fixture underneath the item to be etched including a recessed surface area centered within the bottom fixture; and an etch-resistant window for holding the item to be etched, the etch-resistant window disposed entirely within the recessed surface area. In addition, a small via centered within and intersecting both the top and bottom fixtures acts as a path for a high intensity light beam.

Abstract: A method is provided for allowing a single threaded filter in a print driver to execute feature commands in a parallel mode, thereby creating a pseudo-multithreaded infrastructure which decreases overall processing latency for a print job. The method includes getting and parsing a document sequence print ticket for a document sequence for the print job; creating a feature command list of document sequence scoped feature commands based on the document sequence print ticket; getting a document part and parsing a document print ticket for the document part; inserting document scoped feature commands, based on the document print ticket, in the front of the feature command list; getting a page part and parsing a page print ticket for the page part; inserting page scoped feature commands, based on the page print ticket, in the front of the feature command list; and sequentially executing the feature commands in the feature command list.

The cover support element has two ends, each of which is joined at the upper end of a pair of variable length pivot arms which are pivotable about a lower end thereof at a point intermediate two ends of the container and adjacent the bottom of the container, between a first position in which the cover support element is adjacent a first end of the container and a second position in which the cover support element is adjacent a second end of the container.

Abstract: The present invention relates to a container cover. In particular it relates to a cover for a truck having a material carrying container, such as a roll-on/roll-off truck, skip lorry, or tipper truck. There is described a cover assembly for the container of a vehicle; the container having first and second ends and the cover assembly comprising a variable height tower assembly having a retractable cover with a first end attached to the tower assembly and a second end attached to a cover support element, the tower assembly being movable in height by way of the combined lifting forces of at least one pneumatic cylinder and at least one gas spring, between a first position adjacent the top edge of the container at the first end thereof, and a second position that is more greatly spaced above the top of the container.

Abstract: A cover assembly for a container of a vehicle, wherein the container has a first end and a second end. The cover assembly comprises a retractable cover having a first end attached to a roller assembly and a second end attached to a cover support element, and rolling means adapted to roll the cover upon the roller assembly. The cover support element is supported by at least one pivot arm at an upper end thereof. The pivot arm is pivotable about a lower end thereof at a point intermediate the two ends of the container and adjacent the bottom of the container, between a first position in which the cover support element is adjacent the first end of the container and a second position in which the cover support element is adjacent the second end of the container. The roller assembly is mounted for movement between a lower position.

Abstract: The present invention relates to a truck cover. In particular, it relates to a cover for a truck having a material carrying container, such as a tipper truck or roll-on/roll-off truck. There is described a cover assembly for the container of a vehicle; the container having first and second ends and the cover assembly comprising a retractable cover having a first end attached to a roller assembly and a second end attached to a cover support element; said cover support element having two ends, each of which is joined at the upper end of a pair of pivot arms, said pivot arms being pivotable about a lower end thereof at a point intermediate the two ends of the container and adjacent the bottom of the container, between a first position in which the cover support element is adjacent the first end of the container and a second position in which the cover support element is adjacent the second end of the container; and wherein the union between the pivot arms and cover support element is a flexible joint.

Abstract: A method and apparatus for depositing a uniform coating on a large area, planar surface using an array of multiple plasma sources and a common reactant gas injector. The apparatus includes at least one array of a plurality of plasma sources, wherein each of the plurality of plasma sources includes a cathode, an anode, and an inlet for a non-reactive plasma source gas disposed in a plasma chamber, and a common reactant gas injector disposed in a deposition chamber that contains the substrate. The common reactant gas injector provides a uniform flow of at least one reactant gas to each of the multiple plasmas generated the multiple plasma sources through a single delivery system. The at least one reactant gas reacts with the plurality of plasmas to form a uniform coating on a substrate.

Abstract: The present invention relates to a truck cover. In particular, it relates to a cover for a truck having a material carrying container, such as a tipper truck. A first embodiment includes a cover assembly for the container of a vehicle; the container having first and second ends and the cover assembly comprising a retractable cover having a first end attached to a roller assembly and a second end attached to a cover support element, the cover assembly comprising rolling means adapted to roll the cover upon the roller assembly. The cover element is supported by at least one pivot arm at an upper end thereof, said pivot arm being pivotable about a lower end thereof at a point intermediate the two ends of the container and adjacent the bottom of the container, between a first position in which the cover support element is adjacent the first end of the container and a second position in which the cover support element is adjacent the second end of the container.

Abstract: The present invention is directed to a method of producing a waterborne isocyanate-modified acrylic polymer. The method provides for reacting a compound having at least two-isocyanate functionalities with an isocyanate-reactive polymer to produce the isocyanate-modified acrylic polymer of the present invention having extended shelf stability and solvent resistance.

Abstract: Radiation-curable latex compositions having a secondary curing mechanism are disclosed. In these compositions, an anionically stabilized, water-borne dispersion of one or more radiation-curable resins is combined with a low molecular weight compound having at least two reactive functional groups, wherein one reactive functional group comprises an epoxy and the other reactive functional group comprises either an epoxy or a functionality capable of self-condensation after film formation. Also disclosed is a method for providing a cross-linked protective coating on a substrate, wherein a coating of the composition of the present invention is applied to the substrate, the coated substrate is exposed to actinic radiation to effect curing, and then the unexposed or underexposed portions of the coated substrate are allowed to cure at room temperature or greater.

Abstract: A sanitary dust cap unit is molded of flexible plastics material and includes a cup-shaped cap portion which snap-fits onto a dispensing check valve projecting from a portable metal tank adapted to contain a beverage. The unit also includes an annular retaining loop portion which surrounds the base of the valve and is integrally connected to the cap portion by a thin card-like tag portion having a width greater than the width of the cap portion. The tag portion is printed with information identifying the beverage and/or beverage producer and is flexible to permit the cap portion to be attached to the valve while the retaining portion surrounds the base of the valve.

Abstract: This specification describes means that permit the variation of circuits, particularly latch circuits, used in programmable logic array chips (PLAs). The latch circuits are changeable to enable the selection of one of three different latch configurations to be used or in combination on the same PLA chip. The differences in the circuit configurations of the different types of latches occur only in metallization pattern of the chip so that chips with different latch configurations can be manufactured with a minimum of different processing steps.
