摘要： An attachment is disclosed that is mountable to a scraper blade carried on a powered vehicle such as a log skidder. The attachment is easily mounted and removed from the scraper blade to enable a log skidder to clear roadways of snow and other loose materials. The attachment includes a carrying frame that is releasably mountable directly to the scraper blade. A plow blade is pivotably mounted to the carrying frame. The plow blade is selectively pivotal at its center about a vertical axis to alternate positions forming acute angles with respect to the scraper blade. Therefore, loose material may be plowed to either side of the path desired to be cleared by the blade. Struts are provided that are interchangeable at opposite ends of the blade to enable selective angular positioning of the plow blade.

摘要： A foam-filled cap sealing ink-ejecting nozzles of an inkjet printhead in a printing mechanism has a two-layer structure, with an outer skin layer of an elastomer, and a second foam core layer inside the skin. The skin defines a sealing lip that surrounds the nozzles when the cap is in a sealing position to avoid unnecessary drying of the ink. The skin has an interior surface that defines a cavity under the sealing lip. The foam core, located within the cavity, may be formed by expanding a foam preform or by injecting raw foam into the cavity. An insert may be molded into the cap structure for use in mounting the cap in the printing mechanism. An optional backing layer molded to the structure is used to attach a vent basin to the cap. A method of constructing this cap, and a printing mechanism having this cap, are also described.

摘要： An indicator device for use as a time indicator or a time-temperature indicator. A container is provided for housing a frangible capsule and a porous carrier. A vapor generating chemical is enclosed in the capsule. A mixture, including a second chemical, a pH change responsive indicator, and a gel forming agent are impregnated in the porous carrier. The pH of the vapor is different from the second chemical. A gel is formed from the mixture and provides uniform dispersion of the second chemical and the indicator throughout the porous carrier, as well as provides an impedance to the vapor as it moves through the porous carrier. The device is thus useful as an elapsed time indicator for certain temperature ranges as well as a time-temperature indicator for wider temperature ranges.

摘要： A high-durability flexible bladder designed for placement within in an ink containment vessel. When inflated and deflated, the bladder maintains proper pressure levels in the ink containment vessel which improves the operating efficiency of the entire printing system. The bladder has a specially-constructed side wall that prevents air and ink materials from passing therethrough and is characterized by a high degree of structural integrity and longevity. The side wall is produced from polyethylene naphthalate which provides the benefits listed above. Either a single material layer produced in whole or in part from polyethylene naphthalate may be used or a plurality of material layers can be employed in combination to manufacture the side wall, with at least one layer containing in whole or in part polyethylene naphthalate. As a result, problems involving premature bladder deterioration, leakage, and the like are avoided.

摘要： A free-ink inkjet pen is adapted to be fluidically coupled to a positive pressure, off-axis ink reservoir. The pen includes a pressure regulator mechanism in an ink accumulation chamber fluidically coupled to a print head mechanism maintained at a predetermined back pressure by the pressure regulator. A flexible bag is maintained at atmospheric pressure within the accumulator and acts as an actuator against a pressure regulator bias. In the preferred embodiment, the pressure regulator mechanism includes an actuation lever and a pressure regulation lever biased toward each other. The flexible bag is mounted between the levers where by expanding and contracting both levers are actuated appropriately. A variety of bag fabrication configurations, bag materials, and valve seat materials are disclosed.
