Title: Improvements in or relating to Switching Networks.
IPC: H04Q3/00
Filed: 1966-10-21
Abstract: 1,151,850. Telephone switching arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 21 Oct., 1966 [26 Oct., 1965], No. 47171/66. Heading H4K. In a switching arrangement comprising a plurality of stages of cross-point switching, control of the cross-points which may each have a plurality of sealed contacts is effected by a circuit in response to the marking of relevant starting and end points, which circuit includes matrices of contact operating elements interconnected by networks of conductors corresponding at those in the speech paths, each conductor including holding contacts which are closed or open to indicate whether the relevant intermediate lines are free or busy and a coupling element which may be a transistor connected to permit a flow of current from an output to an input. In the four-stage arrangement shown in Fig. 3 the coil matrice outputs and inputs and the bases of the coupling transistors of two of the stages B.C. are connected to coupling control circuits DSB 1-m , DSC 1-m  corresponding to the switch groups via multipled intermediate cable points, and the multipled outputs from stage D are directly connected to the multipled coupling of the bases of the transistors TCD preceding that stage. The contact operating elements, e.g. coils RD npmq , RC nm1p , RB 1m1n  and RA 11/m  are sequentially energized as the current from the marked output traverses the connecting circuit and establishes the emitter-collector paths of the successive coupling transistors TCD nmp , TBC 1mn , and TAB 11m . Cut-off circuits BS, CS, connected to the coupling control circuits ensure that only one coupling member of a group is activated at any one time, and are described in conjunction with transistor control circuitry for the coupling members in Fig. 4, wherein a marked output cuts-off a normally conducting transistor 1 to create a change of potential across a resistor 7, and thus supply a current to the base of the coupling transistor. The current flowing to the control circuit through the third multiple point 2PB1 increases with the increased conductivity of the coupling transistor to increase its conductivity still more and provide a cumulative build-up to the coil operating point. The input potential to the control circuit, i.e. at 1PB 1  falls as a result of the increased connecting path conductivity and the control circuit and coupling devices return to their rest condition. The - 48 v. power supply may be distributed successively to different transistors 1 in order to avoid repeated operation of the most sensitive circuit.

Title: High frequency electric signal conversion
IPC: H01P5/10
Filed: 1965-11-08
Abstract: 1,092,407. Transforming impedances. A. ALFORD. Nov. 8. 1965, No. 47253/65. Heading H1W. An unbalanced terminal-pair is connected to a balanced terminal-pair by means of a numbeof transmission lines and a single extra conducr tor. As shown, the transmission lines comprise three coaxial lines X 1 , X 2 , X 3  and the extra conductor is in the form of an outer conductor 32 of the same length as the transmission lines (although it may be shorter). At the unbalanced end the outer conductors are connected together by bridges 34, 35, 36 and the bridges are connected to the reference (e.g. ground) conductor 26 of the unbalanced terminals. The signal conductor 24 is connected to each of the inner conductors of X 1 , X 2 , X 3 . At the balanced end the inner conductor of the first transmission line is connected to the outer of the second, and so on throughout the series, the inner conductor of the last 'transmission line being connected to the extra conductor. The balanced terminals are connected to the outer of the first transmission line and to the extra conductor. If n is the number of transmission lines, the transformer presents an impedance at its balanced end n<SP>2</SP> times that presented at its unbalanced end, the selected characteristic impedance of the balancing lines being n times that of the unbalanced input. The lines are preferably one quarter wavelength long at the centre of the operating band. Various modifications may be made to prevent transmission of unbalanced modes, e.g. the linking conductors 50, 54 &c. at the balanced end may be shielded by short sections 46, 62 &c. of outer conductor. A shield 66, which may be extended to surround the balancing lines, may be arranged at the unbalanced end of the transformer. Modifications are described in which the transmission lines and the extra conductor are separately coiled around magnetic cores and these cores may be of such a form as to totally enclose the coils in closed magnetic circuits. A detailed constructional example of a transformer using such cores is described (Fig. 9, not shown). The couplings at the balanced end may be reactive instead of conductive, e.g. the conductors 50, 54 may extend a short distance into the lines X 2 , X 3  &c. without making contact thereby affording a capacitative coupling.

Abstract: 1,061,491. Comparing digital data. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Nov. 29, 1963 [Oct. 1, 1962], No. 47323/63. Divided out of 1,026,171. Heading G4M. [Also in Division H3] Apparatus for comparing the magnitude of two binary numbers A, B comprises digital inputs a k , a k-1  ... and b k , b k-1  ... connected to a network operated by a high-frequency A.C. voltage 11 and including for each input pair a i , b i  a path with one of diodes d1 k - conducting when A=B and paths with one of diodes d2 k -, d3 k - conducting when A>B, A<B respectively. In the illustrated embodiment the reverse resistances of the diodes d1 k - balance one another although two asymmetrical diodes (Fig. 1, not shown) employing two capacitances connected across the terminals of bk may be used. A voltage dividing arrangement r 1 , r 1 1 and r 2 , r 2 <SP>1</SP> compensates for disturbance caused by the internal resistances of the ak inputs. The D.C. control inputs preferably enter at a central neutral point of the A.C. voltage. When using germanium diodes instead of silicon diodes the associated potential differences of equal digits are staggered relative to the different inputs a k , bk; obtained by the input a k  simultaneously delivering two offset voltages and the bk input delivering two voltages lying between those of ak. In this case the windings of the 1: 1 transformers are split to receive the two voltages and a double pair of asymmetrical diodes is used at d 1 k (Fig. 3, not shown).
