Abstract: 1504897 Data transmission L M ERICSSON PTY Ltd 4 Aug 1975 [9 Aug 1974] 32583/75 Heading H4P In a digital data switching system, e.g. a digital telephone system, where it is required to establish a connection between a desired input and a desired output of a digital data switch, a checking procedure to indicate a faulty or a correct connection includes the steps of (a) introducing incorrect parity into one or more words in a digital bit stream applied to said input, and (b) checking the outputs of the switch for said incorrect parity by means of a control unit. As shown, a time-spacetime digital switch 1, 2, 3 of known type receives analogue speech signals at 4. These signals are converted at 5 into corresponding PCM signals and applied to a serial-parallel converter and parity generator 7, the resulting signal passing through the various stages of the switch to a PCM terminal 29 which converts the digital information into analogue form for onward transmission on trunks 30. The input stage 1 and the output stage 3 of the switch are each provided with additional circuitry in the form of a comparator 36 or 43 and a bi-stable register 37 to effect the required introduction of incorrect parity, the registers 37 44 being read by a control unit 31 to effect the checking procedure.

Title: Improvements in or relating to the production of refractory metals
Inventor: JR CHARLES HENRY WINTER
IPC: C22B34/12
Filed: 1956-11-02
Abstract: A refractory metal is produced by reducing its halide under an inert atmosphere by a reducing metal at an elevated temperature, drawing off the resultant reducing metal halide, distilling off the impurities and condensing them in a second reaction vessel containing a new charge of reducing metal to reduce more refractory metal halide, the purified refractory metal being withdrawn from the first vessel.  The reaction mass in the second vessel is now treated as the initial mass, the impurities condensing in the first vessel so that the process is cyclical. The refractory metals are:-Be, Nb, Cr, Hf, Mo, W, Ti, U, V, and Zr.  The reduction is preferably effected at 750-1100 DEG C. and the distillation at 1000 DEG C.

Abstract: 1,241,497. Light scanners. NIPPON SELFOC CO. Ltd. 3 July, 1969 [6 July, 1968], No. 33598/69. Heading H1C. [Also in Divisions G2 and H4] A light scanner comprises a fibrous converging light guide of transparent material having a transverse refractive index variation with the index greatest at the axis of the guide and decreasing with the square of the radial distance from the axis. The guide is fixed at a point 52 and the longer portion 51 is made to oscillate in a transverse plane by the forces between a small attached ferromagnetic body 511 and exciting coils 55, 56, whilst the shorter part 512 is fixed to receive light from a laser 58, the lenses 501, 502 being adjusted to produce the desired spot size and divergence. The light received at a screen 503 may be modulated by a modulator 59 and a two-dimensional picture transmitting system may be formed if a second deflection system is also arranged in an orthogonal transverse plane. In a modification (Fig. 4, not shown), a part of the guide is sandwiched between two electrostrictive elements (44, 45) and the application of an A.C. voltage from a power source (46) causes one element to expand and the other to contract and so sets up the desired oscillations in the guide. In a second modification, Fig. 6, the guide is arranged with a light-pumped laser crystal 68 between a plane mirror 602 and a curved semi-reflecting mirror 603 so that if the crystal is excited and the guide vibrated then the coherent light beam leaving the curved mirror is deflected in unison with the guide vibrations. In all cases described electrostatic deflection forces may be used to drive the guide.
