Abstract: ABSTRACT OF THE DISCLOSURE         Nitroaralkyl cyanides are prepared by reacting a nitroaromatic compound with an alpha,alpha-disubstituted acetonitrile in a substantially anhydrous aprotic solvent and in the presence of a base so that the nitrile undergoes a nucleophilic substitution on an unsubstituted ring carbon of the halonitroaromatic compound during which an alpha-substituent functions as a leaving group.  The nitroaralkyl cyanides formed by the process can be readily converted into derivatives, such as pharmaceuticals.

Abstract: DIGITAL SPEECH CODER       Abstract A sequential pattern processing arrangement is operative to form an efficiently coded signal representative of the pattern.  A sequential pattern, e.g., a speech pattern, is partitioned into successive time intervals. In each interval, a signal representative of the sequential pattern and a signal representative of an artificial sequential pattern for the frame are generated.          Responsive to the sequential pattern representative and artificial pattern representative signals, a coded signal is formed that is adapted to minimize the difference between the sequential pattern representative and artificial pattern representative signals.  The coded signal is utilized to construct a replica of the interval sequential pattern.

Abstract: ABSTRACT OF THE DISCLOSURE            A truck for use on a railway vehicle has 3 axles, one located at each end of the truck and a third located generally centrally between the other two axles.      The two outboard axles are pivotable about respective vertical axes so as to be free to move to a radial alignment when the truck is travelling on curved track.          The axle located generally centrally between the other two axles is free to move laterally but is constrained to eliminate movement about a substantially vertical axis.  Interconnecting means are provided so that the lateral movement of the central axle is used to guide the outboard axles to the radial alignment.

Abstract: Abstract  of the Disclosure A log debarker of the hollow-head type having a rotor journaled in a stator for rotation about a longitudinal axis of the rotor.  A plurality of debarking tools are attached to the rotor for debarking a log being moved axially through the rotating rotor.  Three independently and hydraulically-powered infeed spiked rollers are positioned on the infeed end of the stator for feeding logs into the rotor and three independently and hydraulically-powered outfeed spiked rollers are positioned on the outfeed end.  The rollers are powered at differing rotational speeds to accommodate logs of uneven surfaces.  An air-operated tensioning system including a quick release valve adjusts the position of the infeed and the out-feed rollers urging them towards the longitudinal axis and automatically jogs the rollers open when they are unable to mount a log.  A lubricating system having lubricant filtering and flow control capabilities lubricate and flushes the bearings for the rotating rotor.

Abstract: Abstract:   The disclosure relates to an apparatus for the production of reinforcing non-woven net fabric which is provided with selvage nipping devices for nipping selvages of a weft sheet or loop end portion of weft thread reaches at both sides and advancing the weft sheet with the thread reaches laterally tensioned.  An adhesive applying device coats thermoplastic adhesive onto the weft sheet being nipped by the selvage nipping devices, except at the sel-vage portion of the weft sheet.  A heating device dries and melts the adhesive on the weft sheet and a sheet pressing device presses and bonds together the weft sheet with the melted adhesive thereon and a preheated warp sheet.  Accordingly, during the application of the adhesive, the thread reaches can be maintained exactly straight and in parallel and spaced relationship, and no adhesive is applied to the warp thread, other than at the intersecting points with the weft sheet.  Further, a sheet press device has its peripheral surfaces controlled to keep the temperature lower than the softening point of the ad-hesive, whereby the composite of weft and warp sheets can be easily and rapidly released from the sheet pressing device.

Abstract: ABSTRACT A laser amplifier buffer arrangement for selec-tively switching laser energy in a double pass laser amplifier.  The buffer arrangement comprises a wedge of birefringent material which angularly separates incident laser energy into polarized components, and an electro-optic polarization switch which may be selectively controlled to circularly polarize the polarization components of light passing therethrough. A plane mirror is employed to reflect the polarized components back through the switch and wedge.  The wedge and switch are aligned in a manner such that an arbitrarily polarized input beam is separated into two orthogonally polarizated components that traverse separate paths through the buffer.  The polarized components are reflected back through the switch and wedge by the mirror which is aligned with the normal bisecting the polarization component separation angle. When the switch voltage is off, both polarization components are misaligned with the incident beam energy when transmitted by the buffer, therefore preventing the laser amplifier from superradiant lasing.  With the switch voltage on, the polarizations of both polar-ized components are rotated by 90° in the double pass through the switch, therefore re-entering the wedge with opposite polarizations.  Also, both polarized beams will exit the wedge parallel to the incident beam, thus permitting laser amplifier operation.  A second embodiment is also disclosed which further incorporates a second birefringent wedge and 90° rotator in conjunction with the first wedge in order to produce a wider beam deflection angle and straighten the beam path.  The buffer may also be employed as a Q-switch in a laser oscillator to produce an unpolarized output beam.

Abstract: SCANNING TEMPERATURE DISPLAY SYSTEM            Abstract of the Disclosure A scanning display system for providing a sequential display of a number of temperature signal inputs.  The inputs are coupled through a multiplexer to sequentially produce single output signals, which are in turn scaled and displayed in a digital display.  Some of the inputs to the multiplexer may not be used, leaving certain unused inputs which are sequentially coupled to the output of the multiplexer.  The multiplexer normally advances through the inputs at a particu-lar clocking rate, as determined by a first clocking signal, at a selected frequency.  The scanning display system recognizes the coupling of an unused input to the multiplexer output and advances the multiplexer using a second, higher frequency, clocking signal until the next used input is reached. In this way, only temperature inputs for used channels are displayed in the digital temperature display.  A manually operated switch is also provided to advance the multiplexer through the sequence of input temperature signals.
