Abstract: Peripheral devices of a microprocessor controlled system initiate service request signals which are sent to a system controller over a single dedicated request line. Such request signals are accepted by the system controller on a priority basis, with only one service request signal being honored at any given time. Once honored, the system controller addresses the peripheral device and accepts a vector request word therefrom. The vector request word is then used by the system controller to generate an index signal to select a microaddress of the microroutine to be used to service a peripheral device's request.

Abstract: A display system using the dispersive Faraday coefficient of a magnetic screen to obtain a color display from white light is disclosed. A beam of energy is directed upon a magnetic screen while concurrently an intensity modulated magnetic field is directed normal to the surface of the magnetic screen. The combination of the heating effect of the energy beam and the magnetic orienting effect of the intensity modulated magnetic field established localized areas of differing magnetic characteristics over the planar surface of the magnetic screen. Subsequently, a polarized beam of white light that floods the magnetic screen is, for each of several wave lengths, differently rotated upon passing through each of the areas of differing magnetic characteristics in the magnetic screen. The beamlets that are formed by the so-differently rotated areas of the polarized white light beam are then passed through an uncrossed analyzer, which beamlets appear as a multicolored projection upon the magnetic screen.

Abstract: A timing circuit for a track following servo system wherein an odd servo track having a series of prerecorded odd dibits thereon and an adjacent even servo track having a series of even dibits prerecorded thereon are moved with respect to a servo head to induce in the servo head signals that vary with the occurrence of the dibits and have an amplitude representative of the lateral position of the servo head with respect to the servo tracks. The servo head and its associated preamplifier produce a first signal having portions from both odd and even servo tracks and a second signal that is the inverse of the first signal. The first and second signals are processed by parallel identical circuit paths to generate a clocking signal that times the remainder of the data storage system in synchronism with the spacing of dibits on the servo tracks. Each of the parallel identical circuit paths includes a circuit for discriminating between true dibits and spurious noise signals on the servo tracks, a counter circuit for passing only those dibit pulses that occur within a given time interval after the next preceding dibit, and a circuit for producing a timing pulse at a specified time after the preceding pulse to maintain system synchronization even in the absence of a dibit on one of the tracks.

Abstract: A hydraulic control system comprising a hydraulic actuator having opposed openings adapted to alternately function as inlets and outlets for moving the element of the actuator in opposite directions and a variable displacement pump with loading sensing control for supplying fluid to said actuator. A meter-in valve is provided to which the fluid from the pump is supplied and a pilot controller alternately supplies fluid at pilot pressure to the meter-in valve for controlling the direction and displacement of movement of the meter-in valve and the direction and velocity of the actuator. A pair of lines extends from the meter-in valve to the respective openings of the actuator and a meter-out valve is associated with each line of the actuator for controlling the flow out of the actuator when that line to the actuator does not have pressure fluid from the pump applied thereto. Each meter-out valve is pilot operated by the pilot pressure from the controller.

Abstract: The invention relates to crop harvesting machines fitted with detector means for detecting the presence of undesirable objects such as metallic objects. The invention seeks to solve the problem of known machines in which some form of slipping clutch is provided which operates when drive is arrested due to the presence of an undesirable object and which may overheat, and the problem of normal drive being re-established without first ensuring the removal of the offending object. According to the invention a harvesting machine comprises crop processing means, feeder means for feeding crop material to the processing means, a drive train for driving the feeder means, and detector means for detecting undesirable objects passing through the feeder means, the detector means being operable upon the detection of an undesirable object to initiate instantaneous arrest of the drive to the feeder means and to break the drive train for the feeder means.The arrest of the drive to the feeder means may be virtually simultaneously with, or slightly after, the breaking of the feeder means drive train.

Abstract: A bale retainer finger structure located on a bale wagon along a first table thereof has a pointed tip which will embed into a bale and restrain it from being dislocated toward a bale-receiving end of the first table during the transfer of the bale to a second table on the bale wagon. The finger structure also is mounted for pivotal movement relative to the transfer path of the bale such that its tip completely withdraws from the bale before the bale is completely delivered to the second table but only after the bale has made firm contact with the surface of the second table.

Abstract: A circuit for discriminating among pulses in a series of recurring pulses based on the interval between adjacent pulses which circuit is particularly useful in extracting timing information from a series of pulses such as are induced in a servo head by movement relative thereto of a prerecorded servo track in a disc pack data storage system. The circuit includes a monostable multivibrator for producing a timing signal having a duration corresponding to the time interval between two successive pulses. The monostable multivibrator output is stored, for example in a data flip flop, so as to produce an output pulse from the flip flop if a succeeding pulse in the series occurs while the monostable multivibrator output is high. A feedback circuit connects the output pulse to the timing circuit of the monostable multivibrator to alter the duration of the timing signal produced by the monostable multivibrator in accordance with changes in frequency of the recurring pulses so as to maintain constant the width of the output pulse notwithstanding variation of the frequency of the pulse series. The feedback circuit includes an integrator which effects a reduction in band width of the feedback circuit so that noise pulses or the like that occur at random times have insignificant effect on the circuit and on the output pulses produced thereby.

The antenna system generates symmetrical, matching narrow pencil beam sensitivity patterns by using symmetrically spaced sectorial receiver horns fed energy through a hyperbolic dielectric lens, the horn array and lens residing in a TE.sub.01 mode parallel plate guide, the lens being illuminated by signals collected by a broad wall slotted wave guide array supplied with a thin, planar sheet radome mounted on the energy receiving face of the array.
