Abstract: One embodiment discloses a method and apparatus whereby each time a tape is wound upon a prescribed reel, the winding pattern may be assumed to leave the array of tape edges in a unique "edge profile" represented by the position of each winding edge as viewed from one side of the reel along a radial direction--this "profile" being interpreted as a "winding signature"; the signature may be detected and recorded in a convenient encoded fashion for possible use in uniquely identifying and documenting each unspooling/rewind sequence to thereby monitor tape use.

Abstract: This disclosure relates to a flexible mounting support for a wafer scale integrated circuit system which is adapted not only to support the wafer for maximum cooling exposure but also to contain the necessary driver circuits for the transmission of signals and power between the wafer and the outside world. The mounting support is formed of a plurality of layers with apertures to receive the wafer, which layers are laminated together with certain of the layers being provided with various portions of the lead circuitry required for signal and power transmission between the wafer and the driver circuits and between the driver circuits and the outside world. In particular, this laminated layer mounting support is provided with a mounting layer of a very thin, flexible material and a slightly smaller aperture so that the wafer may be seated thereon and also make electrical contact as may be required for reverse biasing and the like.

Abstract: A four way selector switch for a five port module as a node in an asynchronous speed independent network of concurrent processors, each port of the module including an input selector switch and an output selector switch such that each selector switch has a plurality of output channels one for each of the output arbiter switches (except the arbiter switch associated with its own port). Each selector switch is adapted to select a particular output channel (arbiter switch) according to the initial bits received in the asynchronous speed independent message. In this manner, the module of the present invention can accommodate up to five simultaneous asynchronous message transmissions without nodal blocking although the average number of simultaneous messages that can be accommodated will be less.

Abstract: A digital computer executes a first instruction set in an interleaved fashion with second and third instruction sets, the latter two of which are executed at the same time. The first, second, and third instruction sets together represent an assignment statement of a high level programming language, such as ALGOL and COBOL, and by executing the first, second, and third instruction sets as recited above, a substantial improvement in the execution time of the corresponding assignment statement is attained. A second embodiment executes the first instruction set in an interleaved fashion with only the second instruction set to also achieve an improvement in execution time of the corresponding assignment statement.

Abstract: The disclosed memory cell is comprised of a charge storage region and an adjacent charge transfer channel. A deep dopant layer extends throughout the charge storage region, and a shallow dopant layer extends throughout the charge storage region plus part-way through the charge transfer channel. Overlying the charge storage region is a first conductor that is completely covered by a thick insulating layer. This thick insulating layer also extends into the charge transfer channel part-way over the shallow dopant layer. A thin insulating layer covers the remaining portion of the channel. Lying on this thin insulating layer and extending onto the thick insulating layer is a second conductor.

Abstract: A five port module as a node in an asynchronous speed independent network of concurrent processors, each port of the module including an input selector switch and an output selector switch such that each selector switch has a plurality of output channels one for each of the output arbiter switches (except the arbiter switch associated with its own port). Each selector switch is adapted to select a particular output channel (arbiter switch) according to the initial bits received in the asynchronous speed independent message.

Abstract: Disclosed is an arbiter comprised of two input ports and one output port; each input port has N input data lines, and the one output port has N output data lines; one circuit in the arbiter selects only one of the two input ports at a time; and another circuit in the arbiter passes characters from the selected input port to the output port. Each of the characters is represented by active logic signals on M-out-of-N data lines on the selected input port, with M being at least two and N being greater than M and greater than three.

Abstract: A pivotal feed head for feeding non-rigid paper sheets individually from a feed hopper to a photo-optical utilization station at high speed without interruption, overlap or collision between sheets including oppositely disposed members for applying a normal force between an enlarged resilient tired feed wheel adapted for unidirectional rotation and a conjointly movable, engageable retard roller. The feed head is mounted for pivotal movement about an outboard drive member. A frictional brake for the retard roller is adjustable to provide a preset load at the nip between the feed wheel and the retard roller while a solenoid-actuated one-way clutch operably engages the feed wheel mounting shaft for incremental signal controlled paper feed. A vertical, signal-controlled latching member locks the feed head in a vertical pivoted position at the end of the vertical upward movement of the paper stack platform as the paper is fed into the nip between the feed wheel and the retard roller.

Abstract: Molded optical waveguide switching apparatus wherein a flat, planar light transmissive plastic member of a refractive index N.sub.2 is premolded with orthogonally arranged obverse and reverse grooves or channels and wherein each such channel or groove is filled-in or molded with a light transmissive plastic of a refractive index N.sub.1 (where N.sub.1 >N.sub.2) effectively forming front and back light conducting channels or waveguides at right angles to one another on the flat planar member. A gently curved tap is molded into the intersecting area of each row and column waveguide with a through opening or aperture formed adjacent each intersection. The taps of the obverse side are curved downwardly to meet the upwardly curved taps of the reverse side of the planar member. Light blocking and unblocking members are operably disposed in respective apertures to interrupt light from light generating to light receiving receptors.

Abstract: A multi-plane optical membrane switch for use for example in a keyboard matrix is formed by two flat, planar, clear, plastic members disposed in parallel, separated relationship and each having individual light conducting guides or channels thereon. The channels of the lower plane are disposed at right angles to the channels of the upper plane. The upper set of light guides includes integral, gently curving coupler taps disposed at the intersection of the upper and lower guides for coupling the light from the lower planar guide channels into the upper guide channels when the two channel intersections are pressed together by the key top effectively switching the light from the lower to the upper channels.

Abstract: A servomechanism avoids load-damaging conditions by being shut down whenever a power-amplifier saturation detector fails to detect a change in the saturation state of the power amplifier in response to the periodic and momentary replacement of the demand signal by one or other of two test signals, which of the two test signals is selected being dependent upon the expected direction of possible saturation of the power amplifier and the polarity of both test signals being the same as the polarity of the applied demand signal.

Abstract: Continuous sheet item delaminating apparatus for electrographic drum printing/copying devices including a relatively flat horizontal coupler member having an upstanding vertical attachment portion and a u-shaped portion normal thereto. A plurality of curved, knife edged item picker fingers are mounted between the parallel legs of the u-shaped portion. The vertical attachment portion is pivotally secured to a rotatable crank rotated by a pulley driven from an associated synchronizer. A rocker-idler arm is fixedly pivoted at one end and is coupled at the opposite end to the coupler member such that rotation of the crank causes the picker fingers to follow a four bar coupler curve toward and away from the sheet item effective to lift the forward edge of the item off the drum and permit the item to fall by gravity onto a safe area for further handling.
