Title: Improvements in or relating to pulse transmission systems
Inventor: HARRIS LIONEL ROY FRANK
IPC: H04B14/02
Filed: 1953-08-28
Abstract: 824,481. Automatic exchange systems. POSTMASTER GENERAL. Oct. 19, 1955 [Aug. 28, 1953], No. 23887/53. Class 40 (4). [Also in Group XIX] A closed circulating circuit capable of storing pulses of comparatively short duration is caused to store longer pulses from more than one source by generating shorter pulses therefrom and staggering them before feeding them into the delay line. In the same way if the pulses to be stored are too short to be transmitted in a delay line of prescribed type the pulses are distributed successively to different paths, lengthened and fed to a plurality of delay circuits one for each path, a common recirculating path being provided. In an example of the first embodiment, Fig. 2, pulses from two sources TP5, TP6 are slightly staggered by the inclusion of a short delay line DL2 in the path of the latter. They are then fed to gates PCG3, PCG4 which are opened by short interlaced clock pulses K11, K12, respectively. The pulses are then lengthened at PLM3 to be of duration suitable for transmission over the mercury delay line DLU3, the duration being determined by an inhibiting clock pulse K2. After passing through the delay line the pulses are sorted out by gates PCG5, PCG6 opened again by the clock pulses K11, K12, restored to their original length by lengtheners PLM4, PLM5 and fed to output leads TP7, TP8. A short delay line DL1 restores the original phase relationship between the pulses on the two paths. Each path is back coupled over leads L3, L4 to maintain the circulation. In an example of the second embodiment, Fig. 4, short pulses received over lead TP9 are given a slight delay at DL3 and then fed alternately to paths TP10, TP11 by gates PCG7, PCG8 fed by interlaced clock pulses K11, K12. The pulses are then lengthened at PLM6, PLM7 to have durations suitable for transmission over delay lines DLU4, DLU5. The pulses emerging therefrom are gated at PCG9, PCG10 respectively by the interlaced clock pulses K11, K12, combined and fed to a lengthener PLM8 which restores them to their original duration. A re-circulating path L13 is provided. Application of first embodiment to a time division multiplex system. In such a system the pulse required to connect a particular one of a plurality of outlets to a common highway may be derived by inserting the required pulse into three out of a possible nine circulating systems a pulse derived through coincidence of the outputs from these three systems being that used to effect the connection. Each outlet corresponds a different combination of delay lines. By utilizing the first embodiment of the invention a set of nine delay lines may be shared by two multiplex switches so halving the number of delay lines required. The delay lines may be replaced by other circulating systems, e.g. magnetic drums.

Abstract: 1303482 Printed circuits CARBORUNDUM CO 18 May 1970 [28 May 1969] 23911/70 Heading H1R A printed circuit comprises at least one conductor on a substrate of an oxybenzoyl polyester. Suitable oxybenzoyl polyesters may be those of recurring units of I, or II. Another class of oxybenzoyl polyesters which may be used are the copolyesters of recurring units of I, III and IV in proportions p, q and r, where X is -O-, or -SO 2 -, m is 0 or 1, n is 0 or 1, q : r = 10 : 15 to 15 : 10, p : q is 1 : 100 to 100 : 1, p+q+r is 3 to 600, and preferably 20 to 200. The polyesters can also be chemically modified by various means such as by inclusion in the polyester of monofunctional reactants such as benzoic acid or tri- or higher functional reactants such as trimesic acid or cyanuric chloride. The benzene rings in these polyesters are preferably unsubstituted, but can be substituted with non- interfering substituents. The oxybenzoyl polyesters have low dissipation factors, high melting points, and high resistance to thermal degradation, thus making them suitable for use with high-frequency circuits.

Abstract: 1,168,916. Squaring circuit. PHILCOFORD CORP. 24 May, 1967 [24 May, 1966], No. 24165/67. Heading G4G. [Also in Division H3] In a voltage squaring circuit utilizable, e.g. for conversion of a sawtooth waveform to a parabolic waveform applicable to dynamic focusing of a C.R. tube or for untuned voltage doubling, three transistors 40, 42, 44 have the collectors of 40, 44 connected to a negative source over resistor 14 across which output voltage Eout is developed, while the collector of 42 is connected thereto over variable resistor 46 # 10X resistor 14. The bases are connected to source 16 over common constant current resistor 48  the transistor base/emitter impedances, so that the base currents divide as inverse functions of collector/emitter voltage. Transistor 42 remains conductive and forwardly biases transistors 40, 44 over resistors 47, 49, while the latter transistors respectively increase and decrease in conductivity on positive and negative input voltage excursions, and similarly the output voltage represents the square of the input, as shown by mathematics, (Fig. 2, not shown). The input 20 is connected to the emitter of 40 direct, and the emitter of 44 is earthed over resistor 50, while the emitter of 42 is connected to the slider of a tapped balancing resistor 52 in a symmetrical resistance network interconnecting the emitters of 40, 44. Resistor 32 may be in series with the yoke current of a CRT deflection circuit, and the parabolic output may provide dynamic focus voltage. In a further modification (Fig. 3, not shown) the two transistors utilizing a common collector load resistor operate in saturated mode and supply forward bias to the third transistor which squares both polarities of the input, and supplies an output transistor. A balancing circuit provides symmetry of output waveform, and HF transients may be capacitance filtered. The transistors may be PNP or NPN, and the circuit may operate to square random and a periodic signals.
