Title: Pulse signalling system
IPC: H04B14/02
Filed: 1945-04-06
Abstract: 594,797. Pulse modulators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 6, 1945, No. 8622. Convention date, Aug. 12, 1943. [Class 40 (v)] A pulse transmission system comprises a valve which is rendered conducting periodically by pulses applied to its control electrode, to discharge an energy storage device connected to a second electrode of the valve, and thereby energize a magnetron, connected to a third electrode, with pulses of constant amplitude. In an embodiment for producing pulses modulated in spacing at speech frequencies, peaks of oscillations from a 50 kc /s. oscillator cause a Class C amplifier to conduct and shock excite a heavily damped circuit tuned to 5 Mc /s. The first half-cycle of 5 Me/s. oscillation is differentiated and applied as a trigger pulse to a sawtooth generator V3 which delivers an output at 50 kc/s. to modulator valve V4 in the Figure. Oscillations at speech frequencies are also fed to the grid of valve V4 which is biassed to conduct only at the peaks of saw-tooth pulses occurring during positive half-cycles of speech oscillations. The output is limited in valve stage V5 and consists of a series of pulses spaced according to the amplitude of the speech component. Each pulse raises the cutoff bias of valve V6 and artificial line LC discharges completely through the valve, applying a polarizing pulse of steep rectangular waveform to magnetron 130 which generates oscillations for the constant duration of the pulse. The recharge conditions of the line are adjusted to prevent double pulsing but to allow a complete recharge between pulses. Specification 450,423 is referred to.

Title: Improvements in or relating to tubulous vapour generators
IPC: F22B37/20
Filed: 1963-03-05
Abstract: 1,014,106. Supports and casings for steam boilers. BABCOCK & WILCOX Ltd. March 5, 1963 [March 6, 1962], No. 8693/63. Heading F4A. A tubulous vapour generator includes an enclosure surrounded by a system of tube walls incorporating members for resisting tension exerted transversely of the tubes, with external insulation, and a supporting framework to support the walls against superatmospheric pressure within the enclosure, the connection between the framework and the tube wall system permitting differential thermal expansion. In Fig. 1, the vertical tube wall 11 is fixed to tension resistant members 12, the latter being slidably mounted by bracket 15 on vertical I-columns 16 supported from above, whilst girders 18 slidably link the columns 16 and an end column 22. In the corresponding vertical wall perpendicular to the first, the girder 19 slidably links the vertical columns 16 and an end column 23. The members 12, 13 are slidably linked to end columns 23, 22 by brackets 25, 24 so completing a tensionresistant encircling framework supporting an internal superatmospheric pressure. Lagging is externally fitted to the horizontal members 12, 13. Members 14 reinforce the corners of beams 12, 13. In a modification the vertical columns 16 are welded to girders 18 and the thermal coupling between the members 12 and the vertical columns 16 allows expansion in two directions, by incorporating a horizontal rod fixed to the beam passing through a vertical slot in the column. The end members 22, 23 are also replaced by a single member of cruciform section to which the brackets 25, 24 are both connected. The girders 18, 19 are also connected to this single end column by a pivoted connection. In a further modification, where adjacent vertical tubes carry fluids at two different temperatures causing differential expansion, one set of tubes 62 may be connected as in Fig. 4 to alternate horizontal members 84 whilst the other tubes are connected to the remaining members. A pin 90 fits into a hole in the lug 88 holding the tubes against member 84 whilst a shield 91 is welded to the beam 84 to prevent gas escaping across the tubes 82. As an alternative to the vertical columns extending across the full height of the walls, these columns may be replaced by struts at staggered heights linking one girder to one tension resistant member on either side of the girder, or alternatively linking four such members with two girders. Rollers and other means allow thermal expansion of the walls in two directions. In Fig. 7, the tubes 70 may be horizontal forming the enclosure walls and may be welded to vertical members 72 which are welded to horizontal tension resistant members 75.
