Abstract: DIGITAL AUDIO SCRAMBLING SYSTEM      WITH ERROR CONDITIONING            ABSTRACT OF THE DISCLOSURE    In  the scrambling system,  an analog audio signal  is converted  into  a digital signal to provide a sequence  of digital  signal samples corresponding to the  analog  audio signal.   Each  digital signal  sample  is  compressed  to provide compressed signal samples having a sign bit,  three exponent  bits and seven mantissa bits.   Each bit of  each compressed  signal  sample is exclusive-OR'd with a  unique keystream to thereby scramble the audio signal.  A  Hamming code  generator generates code bits for correcting singular errors in a combination of the sign bit,  the exponent bits and the code bits;  and a parity bit generator generates  a parity  bit for detecting double errors in a combination of the sign bit,  the exponent bits and the code bits and  for further detecting an error in the most significant mantissa bit and/or the parity bit.   The bits from a plurality  of successive  compressed, error-encoded  signal samples  are interleaved  and serialized in order to separate  the  bits from any single sample by at least a predetermined duration associated with an FM discriminator click.  The serialized, interleaved,  error-encoded,  compressed signal samples are combined  to  provide two-bit digital words.   The  digital words are converted to digital PAM data signals which  when converted   to   an  analog  signal  by   digital-to-analog conversion,   provide  a  pulse-amplitude-modulated  signal having  a level related to the binary value of the  digital words.   The  digital PAM data signals are converted to  an analog  signal  to  provide  the  pulse-amplitude-modulated signal.   The descrambler system descrambles the  scrambled audio  signal  by  a process that is the  converse  of  the scrambling process.   Singular errors in a scrambled signal sample  are  detected  and  corrected by  a  Hamming  error corrector.   Double errors in a scrambled signal sample are detected  by  a  parity bit check and  compensated  for  by repeating the last received error tree signal sample.

Abstract: METHOD AND APPARATUS FOR MEASURING ABSOLUTE FIBER JUNCTION LOSS   Abstract of the Disclosure For use in measuring the absolute loss at a junction site between two fibers, two devices for directing light into the fiber from points upstream and downstream of the junction site are coupled to the fiber and remain in their coupled positions throughout the measurement procedure.  A detector unit is then coupled to the fiber just downstream of the junction and used to measure optical powers P21 and P22 resulting from the upstream and downstream launching units respectively.  A detector unit is then coupled to the fiber just upstream of the junction to measure powers P11 and P12, respectively, from the two launching units.  Loss at the junction is then computed from the relationship, splice loss:                     L2 = P21P12/P11P22 A two way detector compensated for bidirectional detection is used. Both the light launching and detection units can be easily coupled to the fiber to permit local, non-destructive splice loss measurement.                             - i -

Abstract: ABSTRACT        A stepping motor of the hybrid multi-phase type is disclosed which comprises a primary element such as a stator which has one winding per phase, a secondary element which can be displaced with respect to the primary element and a permanent magnet.  The pole faces of the magnet are equipped with two pole pieces the ends of which define gaps with the rest of the magnetic circuit in such a manner that for certain relative positions of the primary and secondary elements a closed magnetic circuit is achieved which comprises the permanent magnet and two closed gaps.  The motor comprises, per phase, a second permanent magnet which is also equipped on its pole faces with two pole pieces the ends of which define gaps with the ends of the pole pieces of the first permanent magnet in such a manner that one permanent magnet is in the primary element and another in the secondary element.  Each gap is thus flanked by two permanent magnets, one of which is mobile and the other one fixed, one upstream of the flux circulation and the other one downstream.  In this motor also, this second permanent magnet is oriented in such a manner that the field of the winding of the corresponding phase is perpen-dicular to the direction of its magnetization and directed towards one or the other of the ends of each of its pole pieces defining the gaps, so as to create a flux switching device.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for manufacturing multilayer board in which the pulp suspension forming a surface layer is fed from a  first headbox onto the horizontal section of a first,  inner wire to form a first layer of the web.  The pulp suspension forming an intermediate layer of the web is supplied onto the first layer in or ahead of a tapering gap constituted by the first wire and a second, outer wire. Both of the wires and the web layers between them are subsequently guided over a curved surface.  Then,  the first wire and both of the web layers are guided to converge onto a third wire having a horizontal section of which pulp suspension forming the web of the other surface layer of the board is supplied.  The  consistency of the pulp suspension forming the intermediate layer is substantially higher than that of the pulp suspensions forming the surface layer. The advance in the art is in the possibility of substantially increasing the bulk of the intermediate  layer and thus  of the board,  combined with the benefit  of  reduced  consumption  of  water,  and  no  need  for additional  chemicals,  the last two advantages  contributing to improved overall situation in effluent control associated with pulp board production.
