Abstract: Disclosed is a method of processing documents by moving them from an input hopper to a destination site at a controlled rate, including driving each document into a feed path from the input hopper at an adjustable time period after a previous document had been fed; thensensing the distance separating that document from a following document, and adjusting the time period between driving of succeeding documents to achieve a desired relationship between the document feed rate and inter-document gap.

Abstract: A computer machine module with one, or several, coupling-faces thereof adapted for selective coupling to another like computer machine module, these modules to be coupled to one another by a planar coupling "bridge-structure" to be inserted between opposed faces of the modules, this coupling "bride-structure" having on each side an array of catches formed to engage an array of hooks on each coupling face when the modules are juxtaposed and when the coupling "bridge-structure" is inserted downwardly between the modules and shifted horizontally, with mating electrical connectors on the opposed module faces also being intercoupled by such juxtaposition.

Abstract: A check Sorter-Imager-Processor with two (or more) imaging sites, each lit by a beam through a fibre-optic array, with a lens focusing the beam on each array such that a shift in lens-focus reduces output light from the array,--the two sites being thus "matched" in light-intensity by merely focus-adjusting these lenses.

Abstract: A set of track gauges for use in aligning, focussing and normalizing an imaging system of a high speed document processor have been provided. Each of the gauges fit within a track (14) in front of the imaging system (10 or 12). The depth gauge (70) is used to align the secondary light beam (26) with the primary light beam (22) so that all documents passing through the track (14) will be evenly illuminated from two points symmetrically offset from a line normal to the track (14). In addition, the depth gauge (70) is used to align a normally reflected beam (32) with a photodetector array (56). Two different trunnion mirrors (54 and 28) are adjusted in the two different alignment operations. The focussing gauge (80) includes a set of black 87 and white 88 stripes positioned on a middle region 86. The white reference gauge (90) has a reflective white coating in its middle region 96.

Abstract: A document processing arrangement transporting checks or like financial documents at a prescribed nominal speed along a track, terminated by sort-pockets, each with an associated diverter plus a guide assembly for guiding anddriving a so-diverted document into its pocket, the guide comprising an inject roll to accelerate the document, plus an arm-assembly coupled to rotate with the roll and including an arm for guiding a so-injected document toward its position in the pocket-stack; this roll and arm assembly being arranged to rotate the arm away from its stack each time a document is entering, and also to be spring-driven to return the arm toward its stack.

Abstract: A method for differentiating and separating multiple overlapped like documents from single like items, transported along track means, comprising: subjecting the documents to opposed vacuum forces from suction means to separate them at a separation-station; then determining whether the documents are single or multiple, by measuring and analyzing the resulting pressure differentials within the suction system; using a cyclonic filter for removing and storing dust and debris entrained within the suction-conducting airflow, the cyclonic filter and suction system being designed and adapted to provide a relatively constant vacuum-generating airflow regardless of the nature or quantity of debris removed; plus a pressure sensor for indicating whether one or several documents are passing.

Abstract: Computer apparatus with modular disk drive memory packages adapted to be used/replaced in a common memory stage where each module is to be inserted/renewed in a compartment (bay) thereof.

Abstract: A check Sorter-Imager-Processor with two (or more) imaging sites, each lit by a beam through a fiber-optic array, with a lens focusing the beam on each array such that a shift in lens-focus reduces output light from the array--the two sites being thus "matched" in light-intensity by merely focus-adjusting these lenses.

Abstract: Disclosed is a combined fluid-stream misdirection detector and fluid-level flow detector on a single printed circuit board; each detector comprising a pair of parallel printed circuit segments adapted to be "shorted" by interposition of conductive liquid and coupled to register this event in an associated detect-logic stage.

Abstract: Systems allowing smooth, trouble-free, "transparent" switchover from a "Primary clock" to a "Secondary clock", with no loss of clock or essential pulse-width, and where the "Secondary clock" may be completely separate from, and independent of, the "Primary clock.

Abstract: Described is a multi-module storage array including cabinets, each with a number of identical bays for receiving any of a set of replaceable, modular push-in/pull-out articles, each to be inserted into any bay, each including a carry-handle having an outer bar joining a pair of arms pivoted from opposite sides of the article so that the arm ends can be swung against a first stop to pry-in the article (into its bay) and can also be swung oppositely against a second stop to pry it out, with the handle also adapted to be automatically "kicked-out" horizontal (to indicate readiness for removal) and being held horizontal unit reset.

Abstract: Document-imager for imaging documents (e.g. checks that are transported past an imaging-site, where the site is illuminated by one (or two) pairs of lamps symmetrically disposed about the site, with image-reflection sent back between lamps to be captured.

Abstract: An arrangement for lifting images of check documents at one or more check-imaging stations; each station being illuminated and providing an image-lift optical pathway to an electronic camera, this image pathway including photopic filter means adapted to shift the received spectrum in the direction of optimal human-eye response; the camera being selected and operated to exhibit a spectral response close to that of the human eye.

Abstract: Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means.

Abstract: Salient embodiments comprise magnetic recording sliders whose record-confronting face is characterized by two or three rails wherein stiction forces are counter-acted by provision of a "boss" on one or several rails, or therebetween; and also characterized by provision of a "back-bar" and associated a purge channel; and methods for rendering such are also described.

Abstract: The invention utilizes a single, high-intensity, well cooled source and mounting the light source with associated optical components on a single base under a document transfer track in order to obtain better thermal isolation.

Abstract: A document feed array comprising a pinch-roll mounted to rotate about its center to engage documents, being mounted on a cantilever-arm pivoted at a point distal from said roll-center and including an elastomeric sleeve which, alone, couples the arm to its pivot point (in operation), the sleeve comprising high-damping, durable elastomeric material adapted to accommodate thickness anomalies in said documents, yet to maximize driving contact therewith.
