Title: Arrangements for controlling ram jet units
Inventor: RICHTER GERHARD
IPC: F02K7/10
Filed: 1954-06-22
Abstract: 769,101. Jet -- propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. June 22, 1954 [July 10, 1953], No. 18305/54. Class 110 (3). [Also in Group XXXV] A ram jet unit having means for controlling the position of the inlet shock wave when the unit is moving at supersonic speeds has the fuel supply to the combustion chamber or chambers decreased when the shock wave moves upstream of its prescribed position and increased when the wave moves downstream of this position. A ram-jet, Fig. 3, has three sources of static pressure A, B, C arranged in line along the path of the air passing into the inlet diffuser 1. These static pressures act through a control device 7, shown in detail in Fig. 4, on a valve 8 controlling the fuel supply to the burners 9. The static pressure point A is connected to a chamber 11 containing a capsule 12 connected to the point B, and to a capsule 13 housed in a chamber 14 connected to the point C. When the inlet shock wave is located between the points A and B the pressure in the chamber 11 and capsule 13 is less than that in the capsule 12 and the chamber 14. The capsule 12 is then expanded and the capsule 13 contracted. Switch 17 is as a result closed and switch 21 opened. This causes the electric motor 22 to close the fuel valve 27. The reduction of the fuel supply causes the shock wave to move rearwardly until it arrives at a point between B and C. When this occurs, the pressure in capsule 12 becomes about the same as that in chamber 11 and opens the switch 17. The pressure in chamber 14 remains greater than that in capsule 13 so that the switch 21 remains open. If the shock wave passes to the rear of point C the pressure in the chamber 14 becomes the same as that in the capsule 13 so that it expands and closes the switch 21. This causes the motor 22 to increase the fuel supply. In some cases it is not possible to arrange the points A and B so that the pressure difference between them is zero when the shock wave is to the rear of point B. In these cases the action of the capsule 12 is modified by a capsule 19 responsive to the dynamic pressure on the aircraft acting through a lever 18. The point A may be connected to a pressure detecting device which projects forward of the intake opening and the points B and C connected to other pressure detecting devices or may be mounted on the internal wall of the diffuser 1. In another arrangement the point B is arranged on the external wall of the engine casing. The pressure at this point may be compared with the pressure on the top surface of the wing. When the point C is in the internal wall of the diffuser, the pressure at this point may be compared with the pressure on the exterior of the rear end of the cowling instead of the pressure at the point A. In this arrangement the capsule 13 would be connected to the point B. Specifications 603,155, [Group XXXV], and 710,412 is referred to.

Abstract: 534,208. Electron multipliers. BULL, C. S., and HILL, S. June 26, 1939, No. 18498. [Class 39 (i)] Electron multipliers comprise a series of secondary emissive electrodes 1...4 shaped as described in Specification 520,117, a thermionic cathode C which is the source of the electrons, disposed at the crown of a horse-shoe shaped electrode S, and an apertured electrode E of the same shape as the secondary emissive electrodes. The electrodes E, S are maintained at cathode potential whereby the trajectories of the electrons between the electrode e and the first multiplying electrode are the same as between the successive multiplying electrodes. End effects are reduced by an electrode El welded to the electrode and shaped to coincide with the zero equipotential surface, and by the anode A which is shaped to coincide with the output equipotential surface. The cathode is surrounded by a control grid G and screen grid SG. Part of the latter is removed to prevent escape of electrons from the face F<SP>1</SP> of the cathode. Vaporous or other undesired emission from the cathode is prevented from reaching the secondary emissive electrodes, by disposing the electrodes so that no rectilinear path is provided between them. Specification 507,448 also is referred to. The Provisional Specification describes a circuit comprising an electric discharge device which is so operated that the potentials of the electrodes are such that the cathode current is maintained below the value at which space-charge becomes effective to reduce the ratio of the slope of the characteristic of the device to the cathode current, and in which the spacing between successive windings on the grid are less than, and preferably less than half of, the spacing between the cathode and grid.

Filed: 1928-11-09
Abstract: 321,385. Williams, W. E. Nov. 9, 1928. Divided on 317,301. Directive signalling.-Two or more aerials A, B, Fig. 1, of the three-dimensional or elevatedcapacity type, such as are used for long-wave working, are arranged at such distance apart that any given point a on one aerial is a fixed distance of the order of one-quarter of a wavelength away from the corresponding point b on the other aerial, the separation being in the direction of maximum radiation. The aerials are excited by currents which are out of phase by any angle between 45‹ and 90‹ plus any odd multiple of 90‹. For a quarter wavelength separation and current excitation with 90‹ phase dicerence the polar diagram is as shown in Fig. 2. By reducing the phase-difference to 45‹, the polar diagram is flattened into the form shown in Fig. 3, and is suitable for a broadcasting installation situated near the sea. The direction of maximum radiation is reversed bv changing the sign of the phase difference between the aerials. Polar distribution of any desired pattern, for broadcasting over special areas, can also be obtained by varying the individual directional characteristic of each aerial unit A, B, and by increasing or decreasing their distance apart.
