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: An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.

Abstract: In a check processing apparatus, a technique for separating multiple checks from single like items, these transported along a track wherein the checks are first subjected to twin opposed vacuums to separate them; their state (whether single or multiple) is then determined by measuring and analyzing the resulting pressure differentials within the vacuum-generating system; which is, in turn, provided with a cyclonic filter/suction pump for removing and storing dust and debris entrained within the vacuum-forming air flow, this cyclonic pump providing a constant vacuum-airflow regardless of the nature or quantity of debris removed and collected; the system being also provided with pressure sensor(s) to indicate whether (single or multiple checks are passing, plus a fail-safe unit to warn of vacuum failure. A pressure sensing unit is further provided with a variable damping stage to mask-out minor, insignificant pressure fluctuations.

Abstract: A method for on-the-fly detection and separation of multiple checks or like documents transported in a track, wherein the documents are first subjected to twin opposed vacuum forces from a suction source, to separate multiple documents; then a measuring and analysis of the resulting pressure differentials is taken within the vacuum-forming system; the system being provided with a cyclonic filter-separator upstream of the suction source, for removing and storing dust and debris entrained within the vacuum-forming air flow; the cyclonic filter-separator being designed to provide constant vacuum-forming airflow regardless of the nature or quantity of debris removed and collected; the system also being provided with a pressure sensor to give clear indication of the separated/unseparated state of the passing documents, and to exhibit a variable damping accessory.

Abstract: A computer unit with identical compartments for receiving associated identical memory modules, these modules housing memory means adapted to be removably inserted into a receiving compartment which includes an electrical connector and engagement pin, each module also including an electrical connector for mating with the compartment connector; each module further including its own lever to engage this pin and so draw the module into the compartment, while mating the connectors, or to be reverse-activated to disengage the connectors and help eject the module from the compartment.

Abstract: In a disk drive control stage, data written by a microprocessor to a register (or read by a microprocessor from a register) is automatically "imaged" in a RAM location reserved for that register.

Abstract: A lamp projecting a high-intensity optical beam of spectral radiation, with an IR-extracting (cooling) array including an IR-dissipating "black-box" arranged to receive IR and convert it to box-heat, plus an IR-diverting "hot-mirror" interposed along the beam to divert (only) the IR to this "black-box".

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 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 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 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.
