Title: Improvements in or relating to gas discharge apparatus
Inventor: CARRUTHERS ROBERT
IPC: H05H1/20
Filed: 1959-03-26
Abstract: 876,891. Thermonuclear apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 23, 1960 [March 26, 1959], No. 10501/59. Class 39(4). In gas discharge apparatus comprising means for inducing a pinched ring discharge in gas in a toroidal vessel, the means is adapted to produce a relatively fast initial rise of discharge current followed by a relatively slow rise to the final value. The means may comprise a relatively low-energy bank of "fast" (i.e. low inductance) capacitors which are discharged through a low-inductance primary winding of the transformer producing the ring discharge, and a cheaper form of energy store, such as a "slow" capacitor bank or an inductor, for supplying the remaining energy to a separate high-inductance primary winding. The initial fast rise improves stability and reduces contamination due to material evaporated from the walls; the subsequent slow rise is an advantage if the apparatus includes a toroidal vessel provided with a conducting liner as losses in the liner are reduced. Specifications 830,252 and 843,615 are referred to.

Title: Improvements in or relating to the electrical transmission of pictures, moving objects or the like
IPC: H04N5/202
Filed: 1930-04-03
Abstract: 352,029. Television. STANDARD TELEPHONES & CABLES, Ltd. and BOSS, S. H., Columbia House, Aldwych, London. April 3. 1930, No. 10569. [Classes 40 (iii) and 40 (v).] In a television or copying-telegraph transmitter, vibrating or oscillating means 5, Fig. 1, is in a continuously vibrating or oscillating condition for a predetermined tone value of the object 1 and in a changed condition for a departure from that tone value, and the output of the vibrating means is applied to a transmission line L or is used to modulate a carrier wave. The currents from a photoelectric cell 3 are passed through an amplifier 4, which consists of two thermionic valves in parallel circuits, one with a large negative grid bias and the other with a large positive grid bias, so that the resultant characteristic has a flat central portion, Figs, 2, 3, and 4 (not shown). The amplified currents control a Gulstad relay 5, so that it vibrates for picture tones corresponding to the flattened portion of the amplifier characteristic, and remains on its marking or spacing contacts for darker or lighter tones to transmit continuous positive or negative current from a battery 6 to a line L. The speed of vibration is controlled by a revolving scanning disc 2, and is used for synchronization. Contact in the picture can be modified by adjustment of the amplifier 4. Carrier-current transmission may be used, Figs. 6, 7, and 8 (not shown). The Gulstad relay may be replaced by the thermionic valve circuit shown in Fig. 9. This circuit has two states of equilibrium, namely, when no current is passing through valve 8, and when no current is passing through valve 7. An alternating photoelectric current, produced by a serrated edge on the scanning disc, is impressed on resistance R3 to swing the circuit from one state to the other. Picture currents are impressed on resistance R4, and, beyond a critical value, inhibit the change. Thus, above this value, the plate potential of the valve 8 remains constant, and below, the plate potential has square-topped alternations.
