Abstract: Apparatus for storing documents includes a rectangular housing having first and second openings on a front wall and first and second spaced manifolds mounted on the back wall in horizontal alignment with the openings. A vertically movable rectangular rack is mounted in the housing, the rack having a plurality of pockets whose entrance may be aligned with the openings. Also, each pocket communicates with one of a plurality of sets of holes in the rack, each set being alignable with the manifolds. With vacuum pressure supplied to the first manifold fluid flows through the first opening, through a pocket, and through a corresponding set of holes. Thus, a document inserted into the first opening is drawn into a pocket of the rack. The rack may be stepped along and all of its pockets may be filled with documents. With pressure applied to the second manifold fluid is injected through a set of holes into a pocket and the fluid flows out through the second opening.

Abstract: A stacker includes a rectangular housing within which there is located a vertically movable platform. A vertical wall of the housing includes, along an upper region, an orifice through which sheets may be fed into the housing, and each of the other three vertical walls includes a series of fluid outlet ports, at the same level as the orifice, each series of ports being coupled to a vacuum source. The top of the housing includes an array of fluid inlet ports which are coupled to a fluid source. The fluid source cooperates with outlet ports and vacuum sources to create a fluid stream in the housing which biases a sheet entering through the orifice, selectively, against one of two corners in the housing. Sheets in the housing are also biased towards the platform by movable spring members extending into the housing through the orifice. The spring members are moved out of the way of a sheet entering the housing through the orifice by a detector which controls a solenoid yoked to the spring members.

Abstract: Embodiments of apparatus for fluidically registering or posing documents in copying systems are disclosed. Each embodiment includes: a document feeder; and fluidic means for registering documents at a station and for discharging documents from the station. Discharged documents are collected in a tray.

Abstract: Apparatus for registering a pair of rectangular sheets includes a rectangular sleeve whose width is variable, and a retractable gate located at one end of the sleeve. In a first embodiment, fluid injected into the other end of the sleeve provides first and second fluid streams which register one of the sheets with the gate and one of the narrow walls of the sleeve, and register the other of the sheets with the gate and the other narrow wall of the sleeve. In a second embodiment, the sheets are registered against a centrally disposed vented manifold and the gate. In a third embodiment, fluid drawn into the sleeve provides first and second fluid streams which register one of the sheets with the gate and one of the narrow walls, and register the other of the sheets with the gate and the other of the narrow walls.

Abstract: Xerographic apparatus for reproducing information on selected one of periodically presented documents includes: means for providing print signals time associated with the selected documents; a paper web; toner; and means for providing toner images, corresponding to information on selected documents, on successive sections of the web. The web passes through a fuser assembly whose temperature is sensed and controlled. Control is accomplished with: (1) means responsive to said print signals, for turning the fuser on for periods of time related to intervals of time occurring between successive print signals, each of said periods of time occurring during an interval immediately prior to the presentation of a toner image, related to the first of successive signals, to the fuser; (2) means for turning the fuser on upon presentation of a toner image to the fuser; and (3) means responsive to the temperature in the fuser for inhibiting means (1) and (2) to turn the fuser off after specific timer periods.

Abstract: Apparatus for transporting and cooling toner bearing sheets discharged from a fuser includes a structure having a pair of superposed sheet passageways, the entrance to the passageways being located at one end of the structure. The structure is moved so that successive sheets from the fuser are alternately fed to the passageways and fluidic means move the sheets through the passageways and out of the structure, the directions in which a sheet travels in entering and leaving the structure being, generally, orthogonal.
