Abstract: 1,133,015. Sodium phosphite from sludges. STICKSTOFFWERK PIESTERITZ VEB. 12 Aug., 1966, No. 36222/66. Heading C1A. Phosphorus sludges may be worked up by stirring the sludge with NaOH, the sodium to yellow phosphorus ratio being 1.5: 1, under an inert atmosphere at less than 100‹ C. When the reaction is complete the solution of sodium phosphite is freed from solid impurities, adjusted to a density of 1À40-1À45 g./ml. and cooled. Disodium hydrogen phosphite is crystallized out and the mother liquors are concentrated to a density of 1À35-1À40 g./ml. and cooled to crystallize out more Na 2 HPO 3 . The mother liquors remaining after repeated crystallization are recycled by adding to a fresh batch of sludge after the treatment with NaOH but before the filtration. Phosphine formed during the reaction is led off and burnt to form phosphoric acid in the known way.

A valve, which is adapted particularly for use in a centralized liquid fuel distribution system, comprises inlet and outlet chambers 10 and 11 respectively, which chambers are separated by a centrally apertured wall 9, a float 2 having a stem 12 depending therefrom, the stem carrying a valve member 3 designed to co-operate with the wall aperture and a magnetized plate 4 arranged to co-operate with a magnet 13, a bellows 5 into which the stem extends and which communicates with the outlet chamber via port 15, and a flow supply control 1. In operation, upon the level in the inlet chamber 10 falling, as due the outflow exceeding the inflow or the formation of an abnormal pressure, the float falls, valve member 3 engages the wall aperture, and plate 4 engages the magnet 13, the arrangement being such that the attraction between members 4 and 13 is greater than the float buoyancy and so re-opening of the valve can only be achieved upon the application of an upwardly directed force to the underside of the bellows 5. In a modification, the magnet may be replaced by a suction device adapted to retain the stem in its lowermost, or valve closed, position.

Abstract: 836,265. Charge pumps; regulating. MILLER, R. Nov. 29, 1957 [Nov. 29, 1956], No. 37372/57. Classes 7(2) and 7(6) [Also in Group XXIX] A gas engine, Fig. 1, having an exhaust turbine 50 driving a compressor 30 supplying charge air as via a cooler 36 to the engine cylinder 12 at a rate and pressure which varies directly with load, and which uses reduced cylinder charges at full load by appropriate valve timing, i.e. early or late closing of the air inlet valve or valves 42 and/or partial charge rejection through the exhaust valve or valves 48 being held open on compression, has these valve timings temporarily altered in response to rapid load increase to compensate for temporary lag of the compressor output and thus prevent stalling due to an over-rich mixture. As shown in Fig. 2 applied to a four-stroke engine the air inlet valve cam follower 62 (and/or the exhaust valve follower) is moved by a piston 74 monitored by a valve 1'22 which is under the joint control of the governor 70 for the gas supplied via the valve 46, Fig. 1, and of the compressor delivery pressure acting via a tube 146. Movement of the governor 70 on sudden load increase depresses the parts 128, 130, 122 as a unit and connects a high-pressure oil supply 134 via a duct 116 to a chamber 88 to depress an annular piston 86 sufficiently to connect another high-pressure oil supply 118 via ducts 100, 104, 106 with the space between a partition 82 and the piston 74 to move the latter to vary the valve timing sufficiently to preserve the cylinder gas/air ratio. As the compressor output lag disappears, increased pressure through the pipe 146 lifts the piston 122 and allows the piston 174 to return the valve timing an amount which may be the same as or greater or less than the previous variation according as the delivery pressure of the compressor 30 varies at the same rate as the load or at a greater or lesser rate, to preserve the cylinder gas/air ratio. Timing diagrams for the various valve arrangements mentioned above are given. Instead of compressor delivery pressure a factor indicative of compressor speed may control timing return. With a two-stroke engine, having piston controlled inlet and exhaust ports 154, 156, Fig. 13, the timing of a supplementary exhaust valve 162 may be varied as above, or, as shown, its lift may be altered to give analogous results, using a swinging valve rod 168 connected by linkage 176, 180, 184 with the piston 74, Fig. 2.

Abstract: 1,190,008. Pulse radar. MARCONI CO. Ltd. 25 May, 1967 [23 Aug., 1966], No. 37840/66. Heading H4D. The Specification describes an arrangement wherein the video signals producing a PPI radar display are used to determine, in the case of an airborne radar, the speed of the aircraft, and in the case of a ground radar, the speed of a selected target. In an airborne radar as shown, comprising an antenna 1 scanning in azimuth, the video echo signals arising from one transmitted pulse along a beam making an angle # with the dead ahead direction of the aircraft are extracted from the radar receiver 3 and fed to a switching or gating device 10. The angular space around the aircraft is divided into four sectors, that with 45 degrees > # > - 45 degrees is used to give the forward spread of the aircraft, that with 135 degrees > # > 45 degrees is used to give left drift, that with 225 degrees > # > 135 degrees is used to give backward speed, and that with 315 degrees > # > 225 degrees is used to give right drift. The rotating shaft of the antenna is coupled to a variable capacitor 13 forming part of the tuning circuit of a local oscillator. The capacitor is varied during each sector according to the relation C = Co (1 + tan<SP>2</SP> #), the overall variation being as shown in box X. This causes a corresponding repeated variation of the oscillator frequency f = # 0  Cos #, # 0  being the frequency (approx. 1 mc/s.) when the beam is pointing dead ahead. The sinusoidal output of the oscillator is converted to the square wave shown in box Y. Thus if the aircraft is stationary over homogeneous terrain, consecutive video returns from # = 0, α, 2α ... nα when gated by square waves fo, fo Cos α,#0 Cos 2α ... fo Cos nα give rise to similar signals having no low frequency variation from return to return. Movement of the aircraft however causes the gated signals to differ from consecutive returns with a low frequency variation proportional to the aircraft's speed. If the width of the transmitted pulses Z is made equal to ¢#o, the maximum possible variation will be obtained. To eliminate signals from stationary targets the gated signal portions are switched alternately by switch 10, to two channels comprising low pass filters 17 and 18 feeding a differential amplifier 19. The output of the amplifier, representing the forward or backward speed of the aircraft, or its drift is fed to an appropriate forward speed indication 23 or a drift indicator 24, under the control of a switch 20 which switches over when the antenna sweeps from one sector to another.
