Title: Improvements in or relating to acceleration-limiting devices for aircraft
IPC: B64C13/24
Filed: 1953-11-17
Abstract: 752,089. Controlling aircraft. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Nov. 17, 1953 [Aug. 14, 1953], No. 31892/53. Class 4. In an acceleration limiting device for aircraft the control column 1 is associated with a piston and cylinder arrangement 18, 17, one side of which is connected by pipe 21 to a reservoir B and the other side, by a pipe 16, to a chamber 11 in an accleration-responsive unit. The chamber 11 is connected on one side to a pump P through a restricted orifice 13, a further chamber 12 and a pipe 14 and on the other side to a chamber 6 in communication with the reservoir B through a pipe 15. The chamber 6 surrounds a body 3, which encloses an axially movable weight 4, supported by a spring 5, and is formed with a needle valve 8 associated with an orifice 9 in the wall 10 between chambers 6 and 11. The interior of the body 3 communicates with the chamber 6 and the reservoir B through orifices 7. In un-acclerated flight with pump P operating, the pressure on both sides of piston 18 is the same but if, in the arrangement shown, a vertical acceleration causes the weight 4 to fall by overcoming the spring 5, the valve 8 will close orifice 9 so that the supply of liquid from the pump will be diverted through pipe 16 to one side of the piston 18 in a sense to move the control column 1 in a direction to reduce the vertical acceleration. In a further embodiment (Fig. 3, not shown), a spring-loaded valve is interposed between the chamber 11 and the pipe 16 so that when the valve 8 closes the diverted liquid from the pump does not have to pass through the restriction 13.

IPC: H04N5/14
Filed: 1948-12-14
Abstract: 677,993. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 14, 1949 [Dec. 14, 1948], No. 32244/48. Class 40 (iii). Modulating potentials derived from signals containing a D.C. component are applied to the cathode and control electrode of a cathode-ray tube, e.g. in a television receiver, through coupling circuits each of which passes a different ratio of D.C./A.C., and at least one of which is capable of passing the whole or part of the D.C. component. In one arrangement, Fig. 2, phase-opposed outputs from the anode and cathode of an amplifying valve 1 (to the input circuit 2 of which television signals including the D.C. component are applied) are fed respectively to the control grid 5 and cathode 6 of a picture reproducing cathode-ray tube 7 by means of separate coupling circuits the former of which includes a condenser 10 so that only the A.C. component of the signals is passed whilst the latter coupling passes both the D.C. and A.C. components. To increase the D.C./A.C. ratio in the latter coupling a portion 11 of the cathode resistance is by-passed for A.C. by means of a condenser 12. Modifications of this arrangement are described with reference to Figs. 3, 4 and 5 (not shown). In a further arrangement, Fig. 6, the D.C./A.C. ratio is controlled by means of a degeneration network comprising resistances 16, 17 and 18, and condenser 19 connected in the cathode circuit of valve 1. In another arrangement, Fig. 8, particularly suitable for providing a D.C./A.C. ratio greater than unity, the cathode of tube 7 is D.C. coupled to the anode of valve 1 and the A.C. component is supplied to the control grid 5 from an amplifying stage comprising valve 22, the input to which is derived from the cathode resistor 15 of tube 7. In the arrangement shown in Fig. 9, in which the modulating signals are applied in the same phase to the cathode and control grid of tube 7, only a proportion of the D.C. component, determined by the ratio of resistances 31 and 33, is fed to the control grid 5 and by varying this proportion, which effects cancellation of a proportion of the D.C. component applied to the cathode 6, the D.C./A.C. ratio of the two couplings may be varied. An arrangement in which the control grid and cathode couplings of Fig. 9 are reversed is described with reference to Fig. 10 (not shown). Specification 505,899 is referred to in the Provisional Specification.

Abstract: 310,823. Nance, C. W. Dec. 1, 1927. Treating hides with liquids.-Hides to be treated with liquors for soaking, liming, deliming, and tanning are subjected to a high vacuum in an autoclave containing the liquors and provided with pipes for circulating the liquors on the application of heat. The apparatus consists of a number of autoclaves 1 each provided with a false bottom 13 and with a number of circumferential pipes 12 connected to a perforated pipe 11 arranged near the top of the autoclave. The lower open ends of the pipes 12 extend below the bottom 13 into the liquid, and, on the application of heat and vacuum to the autoclave, conduct the liquid to the pipe 11 from which it is sprayed on the hides. The autoclaves are connected to a foam-trap 8 wherein vertical spiral and horizontal perforated plates separate any liquid drawn out of the autoclave. The foam-trap can be discharged, and the autoclave 2 connected by valve-controlled pipes 3 to the autoclaves 1. Connected to the autoclaves is a cylinder provided with a screw-operated ram 21 for applying increased pressure. The hides are hung in an autoclave and first subjected to a high vacuum to remove any moisture or gas held therein. Water containing a small amount of sodium sulphide is drawn into the autoclave until the hides are covered, and the whole subjected to a high vacuum and a temperature of 90‹ F. The water is then run off, and the hides then subjected to a similar treatment with lime liquor. The hides are removed, unhaired, fleshed, and scudded, and then replaced in the autoclave and treated under similar conditions with boric acid solution and water. The hides are subjected to a high vacuum to remove any air and then to three different tanning-solutions of increasing density and at temperatures of 90' F., 100' F., and 130‹-140‹ F. respectively, the solutions being drawn into the autoclave through chambers in which the gases are withdrawn. During the tanning, the hides and liquors are first subjected to a high vacuum and then to an increased pressure applied by the ram 21. The hides are washed, and dried at a temperature of 120‹ to 140‹ F., and, if desired, impregnated with a waterproofing substance.
