Abstract: 380,138. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. and APPLETON, W. A., 189, Wembley Hill Road, Wembley, Middlesex. June 12, 1931, No. 17167. [Class 40 (v).] In order to eliminate parasitic oscillations in a thermionic oscillator of the type in which.the tuned circuit is effectively connected between plate and grid, phasing inductances are included in the lead or hads to the oscillatory circuit tuning condenser so that the oscillatory potentials at the condenser at any instant are in the same phase as the oscillatory potentials between the anode and grid. In the known arrangement of Fig. 1, parasitic oscillations occur having a frequency determined by the anode-grid capacity of V, the capacity of the tuned circuit C, B and the inductance of the leads connecting anode and grid to C, B. These are eliminated in the circuit of the invention of Fig. 2 by the use of phasing chokes H1, H2 on each side the condenser C; one choke only is effective, but two are preferred. D and E are blocking condensers F is a high frequency choke and G is the grid leak. In a modification, Fig. 4 (not shown), two tuning condensers in series are employed, their common terminal is connected to the cathode and the anode feed is from the mid-point of inductance B ; the same arrangement of phasing chokes is provided. Fig. 3 shows a push-pull oscillator V1, V2 in which the oscillatory circuit B, C is connected across the plate and grid circuits through large condensers D1, D2, E1, E2. The same arrangement of phasing chokes H1, H2 is employed.

Abstract: 1333794 Measuring the speed of bubbles EUROPEAN ATOMIC ENERGY COMMUNITY 26 May 1971 [29 May 1970] 17312/71 Heading G1A In an apparatus for determining the speed of bubbles entrained by a fluid flowing along a tube 1, two separate beams 12 and 13 formed from a laser 9 by a polarizing plate 10 and a prism 11 are passed through the tube 1 at two fixed positions and are received by two separate photo-transistors 7 and 6 as shown. The photo-transistors outputs are fed to a "multi-channel time analyser" to cross-correlate the trains of pulses formed by the bubbles and provide an average time for the bubbles to pass from one radiation path to another. Thus as the distance between the paths are unknown the average velocity can be calculated. In further embodiment the outputs from the photocells are fed to pulse shapers and differentiators and only the positive pulses corresponding to the leading edges of the pulses are fed to the multichannel analyzer. The apparatus can be used to determine the mean size of the bubbles by providing the multichannel time analyzer with pulses of opposite polarity in particular those derived from the same photo-cell output pulse train.

Inking apparatus. -Relates to inking- apparatus for postmarking-machines of the kind described in Specification 170,058. The printing-wheel, 38, Fig. 2, is inked by means such as a pad or roller 123 mounted on a support 124 which can swing about a pivot 23 to move the inker into or out of contact with the printing - wheel. The inker is held in operative position by a latch 125. The meter 31, which supports the printing-wheel, carries a pin 320 which prevents the inker from being turned into operative position until the meter is fully inserted into the machine, and also prevents removal of the meter until the inker is moved into inoperative position. A spring catch 250. engaging a notch in the inker-support, holds the inker in inoperative position, and is dis- - engaged by the pin 320 when the meter is pushed into the machine. The inking-roller is mounted on a slide 127 in the support 124 so that the roller can be adjusted to contact with the printing-wheel bv means of a fixed gauge-pin 25, as heretofore. To prevent the inker from backing away from the printing-wheel, a rack on the slide 127 is engaged by a multiple-toothed pawl 300, Fig. 4, which is held against the rack bv a spring-pressed lever 304. The lever is normally locked by the latch 125, but; when the latch is disengaged, the pawl 300 can be withdrawn from the rack by operation of the lever.

The motor G comprises a casing 84 divided into chambers 88, 90 by diaphragm 92 having a central plate 94 connected to the wedge member 74, and being normally in the broken line position in Fig. 2, due to vacuum in chamber 86 from the engine manifold 30; a central diaphragm portion surrounded by annular abutment plate 110, held away from plate 94 by spring 112, closes an atmospheric port 108, the wedge 74 being retracted and the pedal in the lower position. When insufficient vacuum is recreated by manifold 30 spring 104 will move the diaphragm 92 away from the port 108 and atmospheric pressure entering this port will aid spring 104 in snapping the wedge and brake pedal to the higher position. Atmospheric pressure in chamber 90 will bleed via connection 102, pipes 34 to chamber 32 of booster E to equalize this chamber with chamber 36 which will be connected to atmosphere on brake application to prevent piston 26 moving to close port 68.

When there is more than one dye-forming unit these may be separated by alkaline solution permeable barrier layers to retain the soluble silver ion complexes in their respective dye-forming units. The alkaline processing composition may be contained in a rupturable container. The #- disulphane may be present in the photo-sensitive element before processing, a process sheet or a rupturable container retaining the alkaline processing composition. The alkaline processing composition may have a #H of 11  0.5. The #-disulphone may have the formula:- wherein R 1  and R 2  are each optionally substituted 1-4C alky and R 3  is H or optionally substituted 1-4C alkyl.
