Abstract: 774,475. High-frequency supply systems for space discharge apparatus. TOUVET, G. Jan. 12, 1951, No. 6512/53. Divided out of 774,471. Drawings to Specification. Class 38 (4). [Also in Group XL (a)] Apparatus for producing optical radiation (infra-red to ultra-violet) comprises a gas (particularly xenon) or vapour-filled coiled or folded discharge tube excited by electric current of radio-frequency (or by radio-frequency components of current pulses) between two identically similar electrodes, the frequency, waveform and strength of the exciting current, the composition and pressure of the gas or vapour filling and the shape and dimensions of the tube being so chosen in combination that one or more lines in the spectrum of the filling are split into a multiplicity of lines by the magnetic field set up by the current flowing through the tube and that the intensity of the resulting radiation is enhanced in one or more regions of the spectrum by increasing the amplitude of particular spectral components or by broadening a line spectrum into a band. A coiled tube has a higher self-inductance than a folded tube and is suitable for use at lower radio-frequencies. The radio-frequency of the exciting current may be above 50 Mc/sec. and can be between 60 and 100 Mc/sec. In a particular example described a xenon-filled discharge tube consisting of two coaxial coils is excited by current at 100 kc/sec. Currents of about 1 ampere and 100 amperes per sq. cm. are referred to. Small changes in the frequency of the exciting current cause small shifts along the spectrum of the enhanced bands of the radiation and large changes cause the enhancing of the spectral lines to occur at a different part of the spectrum. The tube can have a sinusoidal input or can be operated in Class B or Class C or by very short D.C. impulses, of the order of 1 microsecond, containing radio-frequency transients. Circuits for exciting the tube are described in Specifications 774,471, 774,474 and 774,477. The tube may form part of the inductance of a tank circuit or may generate oscillations through possessing negative resistance as referred to in Specification 774,471. Applications to television, lowaltitude altimetry, range-finding, radar and remote control are referred to. Specification 386,492 also is referred to.

Information represented by the spacing of adjacent pulses in a train is detected by a system comprising a first storage unit and one or more second storage units corresponding in number to the number of possible intervals between pulses, a value corresponding to the spacing of a pulse pair being transferred from the first unit to the second units which are then allowed to charge their stored value linearly over the following interval between pulses so that for an interval other than the shortest possible interval, one of the second units reaches a reference level. In one embodiment. Fig. 1, pulses B, C, D are derived sequentially from each input pulse so that for each pulse, bi-stable 32 is reset if it is not receiving an input from comparator 28, the voltage on first capacitor 16 is transferred to second capacitors 22 via switches 20, and capacitor 16 is discharged via switch 14. In the interval before arrival of the next pulse, capacitor 16 charges linearly from constant current source 18 and capacitors 22 discharge linearly through the associated constant current transistor 26. If a capacitor 22 fully discharges before the next pulse arrives, the associated bi-stable 32 is set to identify the occurrence of the corresponding interval between pulses, and the current drawn by the transistor 26 in the next pulse interval is modified so that, although a higher voltage is transferred from capacitor 16, the time to discharge to the reference level is the same as for the voltage corresponding to the shortest possible interval.  A functionally similar arrangement using counters advanced by clock pulses instead of capacitors is also described, Fig. 4 (not shown).
