Abstract: 1515711 Data transmission K MIYAZAWA 12 Aug 1975 [21 Aug 1974 6 Sept 1974] 33582/75 Headings H4L and H4P Digital data is transmitted on a relatively narrow band channel by dividing the data stream into successive groups of data pulses, dividing the groups into blocks and modulating each block onto a corresponding one of a series of different frequency carriers, each cycle of the carrier corresponding to one data pulse. In Fig. 9 a register 33 is filled with data bits to form a group. The contents are then transferred to three registers 35, 36 and 37 having 2, 3 and 4 stages, the number of stages corresponding to the relative frequency of three audio frequency carriers so that each cycle can be modulated by one pulse. The modulators 38 comprise a potentiometric carrier frequency path each constituted by a series resistor 38-5 etc. and a shunt transistor 38-4 etc., the latter being switched off by a data 1 pulse via a monostable circuit during the whole of or half of a carrier cycle. In the latter case the other half cycle could be inverted by a full wave rectifier (Fig. 8 not shown). By adding further transistors additional levels of modulators can be effected e.g. to correspond to dibit signals. At the receiver, amplitude sensitive circuits, associated with each carrier, set registers according to the amplitude levels and the outputs from the registers are combined in a common register to reconstitute the data train. The carrier frequencies may lie above a restricted frequency range of a speech channel.

Abstract: 880,094. Charging and discharging condensers. BARDOCZ, A. Oct. 29, 1957, No. 33772/57. Class 38 (4). [Also in Group XL (c)] Spark-generating apparatus such as that used in spectroscopic analysis comprises a condenser C charged from an alternating-current source by way of a saturable transformer T and a rectifier bridge T, the condenser C being arranged to discharge through a working spark gap F in the same half cycle of the supply as that in which it was charged. The waveform of the voltage output of the secondary winding of the transformer T is as shown in Fig. 2d, the condenser C being charged by the voltage peaks and being discharged during the periods of zero voltage. The discharge of the condenser C is initiated by a signal from a pulse generator IG which causes a valve to conduct. The condenser voltage then appears across the upper half of the control spark gap S which breaks down whereupon the condenser voltage then appears across the lower half of the control spark gap S which also breaks down. The condenser voltage then appears across the working spark gap F which breaks down to provide illumination for the spectroscopic analysis. Various other embodiments are described in which the control spark gap S is in the form of a rotating interrupter, in which the breakdown of the working spark gap F is initiated by injecting high-frequency currents into the circuit or in which the circuit is supplied at the third harmonic frequency of the supply by means of three transformers connected to a three-phase supply, the secondary windings of the transformer being connected in open delta.
