Title: Improvements in or relating to electromagnetic wave modulating devices
Inventor: MORRIS ARTHUR LANGLEY
IPC: H01P1/175
Filed: 1957-03-15
Abstract: 846,288. Waveguides. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 11, 1958 [March 15, 1957], No. 8592/57. Class 40(8). [Also in Group XL(c)]  In a ferrite modulator the wall of the waveguide is formed by a helical conductor carrying the modulating current. An insulating layer 3 may externally support the guide and a foam dielectric supporting sleeve 10 may be inserted between it and the ferrite rod 9. The modulator may be terminated by flanges 4, 6, the former conductively connected to it and the latter insulated from it, the modulating current being applied between one end of the helix, through a terminal 7 in the layer 3, and the earthed flange 4. In a modification the terminal 7 is connected to two otherwise insulated abutting helices of opposite hand, each terminating in earthed flanges for connection in a waveguide. The or each modulator helix may be formed electrolytically on a mandrel as described in Specification 846,289 so that the spacing slots are narrower on the outside of the waveguide wall than on the inside, thereby minimizing radiation. High dielectric constant material may be substituted for the spacer 10, or a fluid dielectric may be contained by dielectric bulkheads in the modulator, and cooled by a circulating system having a radiator.

Title: Improvements in or relating to apparatus for controlling the mass flow of fluids
IPC: G01F1/76
Filed: 1947-03-31
Abstract: 639,135. Pressure gauges. NORMALAIR, Ltd., WIDGERY, W. M., SWAFFIELD, P. J., and FURLONG, O. D. A. C. March 31, 1947, No. 8690. [Class 106 (ii)] [Also in Group XXIX] Apparatus for controlling the mass flow of an elastic fluid such as air, i.e. the flow independent of changes in density or temperature of the fluid, comprises velocity-flow measuring means, applied to a duct traversed by the fluid, incorporating two valves disposed respectively at the entrance to and exit from a pressure cavity furnished with a pressure-sensitive element, one valve being actuated by a bi-metallic thermostat or other temperature-sensitive means; and the other by an absolute pressure capsule or the like. In the diagram shown in Fig. 1, air flowing along a duct b, say from a centrifugal blower to a pressure cabin of an aircraft, has pipes 2, 14 connected thereto at each side of an orifice a. The upstream pipe 2 is connected to a tubular cavity 3 in a metering head casing c incorporating a bimetallic strip 4, secured at its upper end and with its lower end engaging a double-ended piston valve 5, which controls the flow of air from the pipe 2 into a cavity 6. The cavity 6 is separated from an adjacent outlet cavity 13 by a flexible diaphragm 7 engaging an adjusting-screw 15 on a spring-loaded arm 16, the arm 16 being adapted to actuate a motiontransmitting unit 18 which controls electrically a mechanical device for controlling the mass flow of air through the duct b. The cavity 6 is connected by a pipe 8 to a second valve housing f wherein an absolute pressure capsule 10 operates a double piston valve 9 to control the flow of air to the outlet cavity 13 which is connected by the pipe 14 to the duct b below the orifice a. In operation, assuming the temperature of the air flowing through the duct b is constant and the density decreases, the pressure head in the pipe 2 will increase, and the deflecting of the diaphragm 7 would normally be increased to cause the transmitter 18 to record a higher mass flow than is actually passing were it not for the expansion of the capsule 10, due to the decrease in pressure in the surrounding air, operating the valve 9 to increase the flow of air from the cavity 6 to the cavity 13. If the air pressure is fixed and the temperature changes, the valve 5 is moved by the bi-metallic strip 4 to control the flow of air into the cavity 6. The invention may be applied to air control systems as described in Specification 639,119, [Group XXXV]. The motion transmitting device 18 may actuate a butterfly valve provided in the duct b, or a sleeve valve which permits escape of air through orifices in the duct.

Title: Improvements in fire-proofing agents
IPC: B27K3/52
Filed: 1934-03-20
Abstract: A fire-proofing agent for wood and other materials is made by chemically enriching an organic compound containing SO2-groups with further SO2 to form a product having a high SO2 content, part of which is lost at high temperatures to yield a compound which checks combustion.  Normal, thickened or bleached sulphite cellulose lye may be treated with sodium bisulphite or by passing SO2 through it at ordinary or raised temperatures.  The product may be made water-insoluble by acetylating and used as an emulsion in water.  The product may also be used for impregnating or coating or as an addition to linoleum, and is also a proofing agent against insects, bacteria and fungi.  In examples, normal sulphite liquor is concentrated by evaporation, 5 to 10 per cent of sodium bisulphite is added and SO2 is passed into the mixture at 50 DEG  C. under 3 atmospheres pressure.  After 1\ba1/2\be days 10 per cent by weight of SO2 has been absorbed.  Alternatively, 10 to 15 per cent of sodium bisulphite is added and SO2 passed in at 120--130 DEG  C. under 5 atmospheres pressure.ALSO:Fire-proof coating compositions for wood and other materials comprise a product made by chemically enriching an organic compound containing SO2-groups with further SO2 to form a material having a high SO2 content, part of which is lost at high temperatures to yield a compound which checks combustion.

Patent GB-1495838-A (GB)
Title: Synchronous shift register
IPC: G06F11/16
Filed: 1975-03-03
Abstract: 1495838 Shift register SIEMENS AG 3 March 1975 [27 March 1974] 8812/75 Heading G4C A shift register is responsive to a timing signal input and control signals to perform input/ shift, parallel input, and clear operations. The shift register comprises a number of storage stages SPG1-3, Fig. 6, each of which is as shown in Fig. 1, two minority logic circuits m (Fig. 4, not shown), and an inverter ND11-3. The circuit of Fig. 1 performs in terms of positive logic signal levels the Boolean function: where Q t0  is the output signal level before a clock pulse and Q t1  is the output signal after the clock pulse. The circuit of Fig. 1 operates with dynamic phase encoded data and control signals as shown in Fig. 3, the negation being because, in the time interval following a clock pulse, the signal level to represent a given logic value is the inverse of that before the clock pulse. If static, level encoded, signals are to be used it is necessary to interpose an inverter between the output of flip-flop SE and the output Q and the feedback loop to cancel the negation. The logic function performed is therefore, in terms of signal level, as given above but without the negation. To feed data serially through the shift register control input ESG (shift) is set to logic value 1, the control inputs GSG (clear), EBG (parallel input) being set to logic value 0, the data is applied to input SEG, and the timing signals to input TE1. In this way the data signal level is applied to both inputs, S and R, of the stages, the above Boolean function causing the inverse levels to appear at the outputs of the stages in the case of dynamic phase encoded signals and the same levels in the case of static signals. If the shift control input ESG signal is removed the outputs of the stages alternate with successive clock pulses in the case of dynamic signals and remain the same in the case of static signals to retain the data. For parallel input of data via lines PG1-3 all the control signals, except EBG which is set to logic value 1, are set to logic value zero so that the R input of each stage is 1 and the S input that of the associated data input. Thus the signal level of the output of each stage, which was initially 0, becomes the inverse of the input for phase encoded signals and the same as the input for static signals. To clear the register all the control inputs, except GSG which is set to logic value 1, are set to logic level 0 so that both inputs S and R are zero. The output of each stage thus becomes 1 and further inputs parallel or serial, may be made.
