IPC: H04L27/18
Filed: 1970-04-23
Abstract: 1289222 Digital transmission systems LICENTIA PATENT-VERWALTUNGS GmbH 23 April 1970 [30 April 1969] 19590/70 Heading H4P In an arrangement for detecting phase difference in a quaternary shift system, wherein recovery of relative phase angles is effected by comparison of the components of successive signal pulses as well as comparison of components of the same pulse, the components X, Y are applied to the inputs of elements S1, S2 each having preliminary stores JK which transfer information each clock pulse A on terminal cl to a bi-stable trigger stage having outputs Q, Q which is transferred on the next clock pulse to similar elements S3, S4. The incoming signal is demodulated in a manner not described and components X, Y are applied to inputs J directly and K indirectly through inverters VI, V2. Elements S1-S4 are connected to NOR circuits 1-4 each comprising two AND gates U1, U2 connected to an inverting OR circuit O1 NOR1, NOR2 detect coincidence between S1, S3 and S3, S4 respectively and NOR3 coincidence between S3, S4; NOR4 detects non-coincidence. In the event of coincidence between input and output of an element e.g. S3 a "1" appears at the output of the relevant inverting OR circuit and a "0" in the opposite case which is applied to one input of an AND circuit U3, and similarly on coincidence across S4 a signal is applied to U4. On coincidence between the information at the outputs of S3, S4, NOR3 responds and with non- coincidence, NOR4 responds, outputs being applied to AND circuits N3, N4 which also receive clock pulses (C, Fig. 2, not shown) time displaced from clock pulses A. The output of N3, N4 is applied to an element S5 receiving clock pulses (B) giving a second input to U3, U4 and through NOR5 to output terminal Ex which has a negative voltage for a "1".

Abstract: 1296034 Radio signalling; frequency division multiplex POST OFFICE 26 Jan 1970 [4 Nov 1968] 52206/68 Headings H4L and H4R A frequency-division multiplex communication system carrying a number of speech channels groups the channels in pairs with each pair allotted to a separate frequency band, the speech frequency components of one channel of the pair being " inverted " in frequency relative to the components of the other, and the parts of the band utilized by the two channels only partially overlap so that on reception the lower frequencies of each are free of interference. Since the voice energy is largely concentrated under 1 kHz, it is stated that interference between higher frequency components can be acceptable. The Specification describes the conversion of a group of 12 speech channels each occupying approx. 3 kHz of a 4 kHz band in the range 60-108 kHz to pairs in six bands by modulation of an 84 kHz carrier, the lower sideband of 0-24 kHz being selected and converted to 84-108 kHz by further modulation and frequency filtering. A similar arrangement is used to " fold-over " a second set of twelve channels to produce a set of six bands in the range 60-84 kHz and the two sets are transmitted together. On reception after demodulation using an 84 kHz oscillator the 4 kHz bands are separately selected by frequency filters and the " erect " channels each subjected to lowpass frequency filtering (cut-off 3 kHz). The " inverted " signal of the same band is obtained by frequency inversion and similar low-pass (3 kHz) filtering.

Abstract: 1305174 Mounting semi-conductor devices STANDARD TELEPHONES & CABLES Ltd 23 March 1971 7546/71 Heading H1K A number of wire leads, of enamelled copper, are moulded into a plastics body to lie within the body and to extend therefrom. The plastics body is treated in manufacture so as to provide a mounting area for a solid state device and adjacent areas at which the ends or sides of the wire leads are exposed to provide termihal points to which and to the device electrodes flying leads may be ultrasonically bonded. Fig. 11 shows the simplest case in which the ends of the wire leads are exposed at one face of the body 31 (and extend from the opposite face) and are connected by flying leads 34 to the device 33. Fig. 4 shows another construction. Its manufacture can best be understood by imagining the structure to be inverted. The wire leads 7 (then without the body 13) are wound by conventional coil-winding machinery to form a single-layer coil. (Adequate tension may be maintained by making the mandrel as two sprung apart halves, though this is not done in the particular embodiments.) Shuttering is then applied to the mandrel so that body 13 may be cast around the wire leads. The leads are then severed along a line opposite the moulded body and the structure removed from the mandrel. Now considering the drawing with the orientation shown, the top surface between the ribs 15 is slightly ground to different extents-in the contact area it is ground down to sever the wire leads and provide the device mounting area and in the two adjacent areas it is ground down sufficiently to expose the sides of the wire leads and to remove the enamelled insulation on the exposed sides. In a variant (Fig. 5, not shown), the wire leads are severed on the mandrel at the point adjacent the moulded body so that they project from one side of the body only. The central mounting area of the body is then left as a raised platform through which the wire leads pass, their sides being exposed by grinding down areas adjacent the mounting area as before but this time the same wire is exposed twice, once on each side of the mounting area.
