Abstract: Abstract of the Disclosure In an adaptive equalizer of the decision feedback type for reducing intersymbol interference in subsriber loops of a telephone system, the corrected digital signal is applied to a device for detecting the occurrence in the signal of a zero state following a non-zero state.  When that occurs, a correlator samples the signal during the "zero" bit period and applies the sample to an integrator.          The integrator output varies the coefficients of the feedback signal applied to the input means for addition to the incoming digital signal to provide the corrected signal. The equalizer may have several stages, each for detecting a "zero" state in a different bit period following the original pulse.  Also the circuitry may be duplicated for each polarity if the input signal is bipolar.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE     A firearm comprises a barrel having a bore and a receiver forming an ignition chamber.  A bolt is slidable in the ignition chamber and includes a striker projection for igniting a primer of the projectile.  A bolt advancing mechanism comprises an arm having a first end mounted on the bolt such that a second end of the arm is movable laterally relative to the fore-aft axis.  A boss is carried at the second end of the arm.  An actuator member is movable in the fore-aft direction relative to the bolt and boss, and includes a first cam surface inclined relative to the fore-aft axis for urging the boss forwardly and laterally.  The boss is movable laterally along the first cam surface in response to the boss becoming aligned with a lateral groove in the receiver.  Such lateral movement of the boss is in a direction tending to displace the bolt forwardly.  The actuator member (i) pushes the boss and bolt forwardly to shift the projectile to a firing position, (ii) cams the boss into the groove to further displace the bolt forwardly and ignite the primer, and (iii) blocks movement of the boss from the groove until ignition occurs, whereupon a second cam surface displaces the boss outwardly.

Abstract: ABSTRACT.            "Method and apparatus for a phased array transducer".     A stacked phased array type of transducer has a single electroacoustic transducer element supported inter-mediately of an elongated tube having a plurality of ports and an end wall at each end thereof for transmitting and receiving acoustic waves broadside the longitudinal axis of the array tube. The element has a first vibratile surface in direct acoustical communication with the ex-ternal transmission medium and a second vibratile surface in direct acoustical communication with the tube internal transmission medium. The tube is provided with at least one annular port spaced longitudinally from each end of the element for providing acoustic coupling between the intern-al and external transmission mediums with the tube interior providing acoustic transmission paths internally of the tube communicating between the second vibratile surface and the external transmission medium at each one of the ports. The physical spacing of the ports, the aperture area of the ports, the effective acoustical wave path length internally of the tube, and the acoustical impedance of the end walls of the tube are configured to provide predetermined phase shift and acoustic transmission charact-eristics of the transmission paths between the second vibratile surface of the transducer element and the external transmission medium immediately adjacent each port to provide a maximum acoustic wave pattern broadside or per-pendicular to the longitudinal axis of the tube. Baffles are provided to phase shift control the acoustical wave internally of the tube. In an embodiment transducer elements and ports are alternately positioned along the tube length.

Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus disposed within a computer system is disclosed for sensing the existence of an error occurring within a computer system and for suspending an internal system clock when a certain number of clock pulses are generated following the occurrence of the error.  When the internal system clock is suspended, operation of the computer system stops.  In the preferred embodiment, the internal system clock is suspended when two (2) clock pulses are generated following the occurrence of the error.          As a result, it is not necessary to wait until execution of the current instruction is complete before stopping the operation of the computer system.  Therefore, other errors are not generated within the computer system as a result of the generation of the initial error.

Abstract: ABSTRACT    A torque multiplier subsea tool for setting a seal between a casing hanger and a subsea wellhead includes a mandrel having a sun gear with axial elongate teeth.  An outer barrel is disposed around the mandrel forming an annulus therebetween.  A planetary gear assembly is disposed in the annulus between the barrel and the sun gear to transmit to the barrel a torque which is higher in magnitude than that applied to the mandrel.  A connector body disposed around the mandrel, below the planetary gear assembly, includes radially movable dogs for engaging the casing hanger.          The barrel engages the sealing assembly and transmits the in-creased torque thereto to advance the sealing assembly downwards and to set the seal.  The mandrel advances downwards with the sealing assembly and releases the dogs from the casing hanger.          An emergency release mechanism is provided to advance the mandrel downwards to release the dogs in the event such downward movement is prevented during normal seal setting operation.

Abstract: NITSINITRIDE AND OXIDIZED NITSINITRIDE DIELECTRICS ON SILICON    Abstract of the Disclosure In an integrated circuit process a composite dielectric layer is formed on a monocrystalline, polycrystalline or amorphous silicon substrate by thermally growing a first silicon nitride layer from a surface layer of the silicon and then depositing a layer of amorphous or polycrystalline silicon.  A second nitride layer is thermally grown from the deposited silicon to form a nitride-silicon-nitride, termed nitsinitride, composite dielectric.          At least a top layer of the nitsinitride dielectric can be oxidized to produce an alternative composite dielectric, termed oxidized nitsinitride.  Variation of the thickness of the dielectric layers and/or repeating the layering process sequence results in composite dielectrics of different thicknesses and dielectric properties.

Abstract: Abstract "Filter arrangement."     A first resistor (R1) and a first capacitor (C1) constitute a filter arrangement having a time constant which is not very accurate due to the inaccuracy of the resistor and the capacitor values in intergrated circuits. The time constant is adjusted using a circuit comprising a reference resistor (R2) and a switched capacitor (C3). The value of the reference resistor (R2) and the equivalent resistance of the switched capacitor (C3) are compared by means of an integrator (C2, 2) from whose output (9) a control voltage is taken via a hold circuit (C4, C5), which control voltage is equal to the voltage at that point on the reference resistor where the resistance value is equal to that of the switched capacitor (C3). By means of comparator (21 to 30) and switches (S11 to S20) a percentage of the total resistance of the first resistor (R1) is short-circuited, which percentage is equal to the difference between the resistance of the reference resistor (R2) and the equivalent resistance of the switched capacitor (C3), expressed as a percentage of this equivalent resistance.
