Title: Improvements in and relating to regulating mechanism for prime movers
IPC: G05D13/00
Filed: 1932-12-23
Abstract: 399,682. Speed governors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Standerwick, R. G. ; 17, Brookhouse Drive, Marblehead, Massachusetts, U.S.A.) Dec. 23, 1932, No. 36478. Convention date, Dec. 26, 1931. [Class 57.] A speed governor 29 actuates through the fluid relay 28 the pilot valve 19 of a fluid relay 12 actuating the throttle valve 2 of a turbine 1. Movement of the valve 2 is transmitted through links 58, 57 to a pilot valve 52 which causes a piston 46 to operate to alter the position of the fulcrum 23 to counteract the movement caused by the speed governor so that the valve 2 returns to its original position, i.e. the load output of the turbine returns to substantially its original value. The faces 63 of the pilot valve 52 are shaped to retard the flow of pressure fluid causing the alteration of the fulcrum 23 to be delayed. Stops 64, 65 are provided to limit the movement of the fulcrum so that outside this range the speed governor acts upon the valve 2 in the normal manner. The system may be applied to the machines carrying the base load in a power plant so that for small changes in speed the plant returns to its normal load output and the variation in load on the plant is taken by the peak load machines.

Title: Improvements in or relating to electron velocity modulation tubes
Inventor: LAMBERT DONOVAN ERNEST CHARLES
IPC: H01J25/06
Filed: 1958-11-14
Abstract: 861,009. Velocity-modulated tubes. STANDARD TELEPHONES & CABLES Ltd. Nov. 14, 1958, No. 36704/58. Class 39(1). In an electron velocity modulation oscillator a ribbon-shaped beam of electrons is projected across a resonant length of hollow rectangular waveguide with the width of the ribbon normal to the direction of propagation of TE waves in the guide. A drift tube is arranged to surround the electron beam within the guide and to provide an interaction gap at each end. The drift tube 5, Fig. 3, may be supported from the side walls of the guide, or may be insulated therefrom and used to impart frequency modulation. As shown, fins 8 project from the wall of the guide to provide interaction gaps of an optimum length. The resonant length of waveguide communicates through reactive diaphragms 10, 11 with an adjustably tuned resonator as described in Specification 861,008 at one end and an output waveguide 91 fitted with a capacitative impedance-matching slug 95 at the other, the central waveguide portion being hermetically sealed by waveguide windows 14, 14<SP>1</SP>. In assembly of the device the resonant length of waveguide together with cathode 3, grid 4 and collector electrode 7 are mounted on valve base 17, Fig. 4, and inserted in an elongated envelope 19 of rectangular crosssection. Mica windows 14 and cups 15 are sealed to each other and to envelope 19 as described in Specification 859,887. Waveguide flanges 12, 13, spaced by struts 16, are secured to cups 15 and a magnet 20 is clamped therebetween in such manner that it can be moved parallel to the flanges or tilted by means of adjustment screws. A metal cooling block 40, Fig. 12, is secured to the waveguide and sealed to one end of the envelope. To maintain the interaction gaps constant despite thermal changes, fins 8 are of a copper-nickel alloy while drift tube 5 is a laminated construction of sheet molybdenum, gold, fused together. The drift tube is so dimensioned as to minimize the excitation of TEM coaxial modes in the resonator, and is provided with a partition 64 to prevent radiation from the structure. Wave damping is applied to the electrically open end of the coaxial line formed by the drift tube and resonator by means of insulator 62, Fig. 13, of high loss ceramic material. The end 71 of the drift tube 5 is clamped between cooling block 40 and metal plate 61 between insulating strips. The plate 61 and block 40 form a quarter wave openended strip line which rejects power at the operating frequency. The drift tube potential lead 79 is connected to the tube within this line and is led through an insulating bushing 81 traversing the cooling block, the lead and block thus forming a coaxial line.

Title: Improvements in electric relays
IPC: H01H50/36
Filed: 1929-12-12
Abstract: 350,487. Light current relays. REGNAULD DE BELLESCIZE, H. J. J. M. DE, 47, Boulevard de la Seine, Neuilly-sur-Seine, France. Dec. 12, 1929, No. 38099. Con. vention date, Dec. 12, 1928. [Class 38 (v).] A sensitive relay is provided with adjusting means of the airgap, return spring, contacts, polepieces, &c., such that the curves representing the relationship between the electromagnetic controlling force and the resilient opposing force are tangential at a point representing the neutral position of the armature. The relay may be constructed as shown in Fig. 1, in which a U-shaped core 1, 2, 3 carries a winding 6 moving an armature 4 between adjustable contacts 13, 14 controlling circuits containing resistances 10, 11. A second polarizing winding (not shown) may be provided. In an alternative arrangement (Fig. 2, not shown), the armature is pivoted upon a knife-edge formed on one of the limbs of the U-shaped core, and is acted upon by a return spring. The operating and controlling forces are made adjustable so that the armature may be retained in a neutral position between the contacts, adjustment being effected by means of the control spring or by means of an adjustable polepiece 17. This adjustment is such that if the curves showing the relationship between the electromagnetic force acting on the armature and the resilient force opposing it (ordinates) with the displacement of the armature (abscissae), the two curves 22, 32, Fig. 3, are tangential at a point 33 representing the neutral position of the armature corresponding with a current I through the relay winding. This condition is obtained by adjusting the electromagnetic force or adjusting the resilient force or both. The travel of the armature on each side of this neutral position is varied by adjustment of the contacts. To obviate irregularities caused by hysteresis in the metal the core is formed partially or wholly of an iron alloy of high nickel content.
