摘要： In the particular embodiments described in the specification, a hot melt ink jet system includes a temperature-controlled platen provided with a heater and with a thermoelectric cooler electrically connected to a heat pump, and a temperature control unit for controlling the operation of the heater and the heat pump to maintain a substrate on the platen which receives the ink at a temperature which provides a desired spot size without causing print-through. In certain embodiments, the substrate temperature is from about 20.degree. C. above to about 20.degree. C. below the melting point of the ink and is determined by subtracting half the difference between the jetting temperature and the temperature at which the ink has a viscosity of about 200-300 cp from the latter temperature. The apparatus also includes a second thermoelectric cooler to solidify hot melt ink in a selected zone more rapidly to avoid offset by a pinch roll coming in contact with the surface of the substrate to which hot melt ink has been applied. An airtight enclosure surrounding the platen is connected to a vacuum pump and has slits adjacent to the platen to hold the substrate in thermal contact with the platen.

摘要： In the representative ink supply system described in the specification, continuous circulation of ink in an ink jet head is accomplished by providing two reservoirs connected to each ink jet orifice through corresponding passages so that ink flows continuously from a high-level reservoir past the orifice to a low-level reservoir. The difference between the levels of ink in the reservoirs is maintained relatively constant by inertial pumping during reciprocal motion of the ink jet head or by pressure transfer of ink from one reservoir to the other reservoir. Cross-flow purging of air or debris from the ink jet head is effected by covering the ink jet orifices and applying air pressure to one reservoir to cause ink and any trapped air or debris to flow from the head to the other reservoir. A pump responsive to reciprocal motion of the ink jet head generates a positive air pressure which is applied during purging and a negative air pressure which is applied to a deaerator for removing dissolved air from the ink.

摘要： A document printer includes sheet-feeding apparatus for sequentially presenting both faces of a print-receiving sheet to a print station. According to a preferred embodiment, such apparatus features, as part of the duplex sheet path, reversible sheet-feeding means operable in first or second active modes for selectively feeding sheets into and out of a chute, located upstream from the feeding means, to reverse the sheet's lead edge/trail edge orientation. Such sheet-feeding means is also operable in a passive mode in which it allows sheets to advance, without substantial interference, downstream therepast to a registration position. Control means are provided for switching the feeding means from one of its active modes to its passive mode after a sheet has been advanced into the reversing chute to the extent that the sheet buckles, whereupon the restoring force in the sheet propels the leading edge of the sheet past the feed means and into engagement with a registration gate located at the registration position.

摘要： In a document handling system in which an apertured vacuum belt transports the documents to the imaging station of a copier and provides a light reflective background surface, the belt vacuum apertures are only within discrete limited areas of the belt and have a convoluted surface which holds the document spaced from the vacuum apertures and provides low impedance air flow under the document from the apertures, said areas being substantially enclosed by narrow border areas of unapertured and non-imageable pneumatic weirs at positions corresponding to the edges of conventional sizes of documents, which weirs are finely convoluted to have a much higher air flow impedance.

摘要： An apparatus in which articles are stapled to one another. A staple is driven through the article so that a portion thereof protrudes therefrom. The staple legs protruding through the articles are bent into substantial contact therewith so as to clinch the staples. In the clinched position, the staple legs are closely adjacent to one another and may be overlapping. During the clinching operation, the staple legs are guided by a groove in the surface affecting bending. Initially, the stapled leg is received in the central region of the groove. The central region of the groove has a greater cross-sectional area than the end region thereof.

摘要： A method for preparing a transparency involves application of hot melt ink to a transparent substrate to form a three-dimensional pattern with subsequent heating of the hot melt image above its melting point to change the configuration of the upper surface. In the embodiment described in the specification, a hot melt ink image on a substrate is treated in a continuous manner by moving it along a platen having a heating zone to melt drops of hot melt ink and cause them to spread on the substrate. The platen has a flat central portion and curved portions at each end with curvatures sufficient to prevent formation of cockle. At the output end of the heating zone, the substrate is moved continuously into a quenching zone where a cooling platen cools the substrate by thermal contact at a rapid rate to prevent crystallization or frosting of the hot melt ink image. After the quenching zone, the substrate is moved along a surface having a reverse curvature with respect to the curved portions of the heating platen to eliminate residual curvature of the substrate resulting from the curved portions of the heating platen.

摘要： In the ink jet printing system described in the specification, a hot melt ink jet printhead having two ink reservoirs is coupled through an ink supply line to a remote hot melt ink supply and a temperature controller is arranged to control the temperatures of the ink in the remote ink supply, the supply line, the ink reservoirs in the printhead and passages leading from the reservoirs to the ink jet orifices at selected temperature levels to inhibit high-temperature degradation of the ink while permitting the ink to be jetted at the desired jetting temperature. In addition, a pressure control system controls the pressure of the ink in the printhead at one or more selected levels to permit the printhead to be used at different orientations and to permit purging of air bubbles and contaminants from the orifice passageways and to supply a relatively high vacuum to a deaerator in the printhead to extract dissolved air from the ink. A check valve in the ink supply line permits the printhead to be positioned at different elevations with respect to the remote ink supply without causing any undesired flow of ink between the reservoir and the printhead.
