Title: Improvements in the method of and apparatus for automatic control
IPC: F01D17/26
Filed: 1924-02-28
Abstract: 234,194. British Arca Regulators, Ltd., and Lindsay, T. Feb. 28, 1924. Valves controlled by pilot or relay valves.-A controlling device particularly applicable for controlling the flow of a fluid, an electric current, the speed of machinery, humidity or temperature and of the type in which variations of the pressure of a non- compressible fluid continuously passing through a discharge aperture are used for controlling the. operation of the device, is provided with means for producing and transmitting by said non-compressible fluid a compensating impulse adapted instantaneously to check the tendency of the apparatus to over or under-regulate. The Figure shows the application of the invention to the control of pressure in a steam pipe. The main valve 3 is opened against the action of a counterweight 10 by fluid pressure acting on a piston. Pressure is admitted to or exhausted from the cylinder through pipes 13, 19 under the control of a double-seated valve 14 itself actuated bv a spring-loaded diaphragm &c. Pressure fluid is admitted to the diaphragm chamber through a. pipe 20 and needle valve 18, and is exhausted through a pipe 20 and discharge orifice 23. The rate of discharge from the orifice 23 is controlled by a cup 31 mounted on a lever 37 with knifeedge pivots 37 and actuated by steam pipe pressure acting on a bellows 34 against the action of a spring 38. The lever 37 is elastically connected to a second spring-loaded lever 40 actuated by a bellows 43 subject to the pressure in an air vessel 48. The lower part of the air vessel is connected by a conduit 46 controlled by a needle valve 47 to the power cylinder so that when the pressure is increased or decreased in the power cylinder a corresponding impulse is transmitted to the bellows 43 tending to restore the cup 31 to its original position.

Title: Improvements in or relating to sound recording systems
IPC: G11B7/00
Filed: 1941-04-24
Abstract: 548,460. Optical sound recording apparatus. RADIO CORPORATION OF AMERICA. April 24. 1941, No. 5311. Convention date, Dec. 29, 1939. [Class 40 (ii)] Sound is recorded in variable-density on a film and simultaneously therewith the width of the track and the average density are both varied in accordance with the average value of the sound. In the apparatus shown in Fig. 1, sound is picked-up by a microphone 26 connected by an amplifier 27 to a variable-gain amplifier 29 and a noise-reduction amplifier 28. The variable-gain amplifier 29 feeds the coil 32 of a mirror galvanometer 18 ; and the rectified output of the noise-reduction amplifier 28 is passed in series through the amplifier 29 to control its bias to vary its gain, through the coil 12 to control the position of shutters 10 to determine the width of the track, and through a coil 34 in the galvanometer 18 to control the average density of the recording beam. Adjustable resistances 13, 41 are provided across the coils 12, 34 and an adjusting screw 39 is fitted to the galvanometer 18 to make initial adjustments. The light beam originates from a lamp 5 and is directed by a lens 6 to a mask 7 having a rectangular slot 8 against which the shutters 10 operate, a stop 42 being provided to limit the movement of these shutters. The light then passes over a penumbra mask 15 and through a lens 16 to the galvanometer mirror 17 and thence through a slit plate 20 and a lens 22 to the track 23 of the film 24. The record produced is indicated in Fig. 2.

Abstract: 852,421. Velocity modulated tubes. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. Feb. 12, 1957 [Feb. 21, 1956], No. 5363/56. Class 39(1). A velocity modulated discharge device has an input and output resonator 5, Fig. 1, and an output feeder-a waveguide or coaxial lineextending axially from the output end of the device which has a vacuum gas seal 11 transparent to the RF energy and a collector 8 surrounded by a cup shaped X-ray shield 9 which shields the vacuum seal 11 from X-rays generated at the electron collector, the X-ray shield 9 or a casing 17 therearound and the surrounding wall of the discharge device forming a concentric line coupling for transmitting microwave energy from the output resonator 3 past the X-ray shield 9 to the output feeder. The X-ray shield 9 may, Fig. 1, or may not, Figs. 2, 3 (not shown), form one conductor of the concentric line. An additional X-ray shield 16, Fig. 1, may protect the operator. A coupling loop 13 couples the output resonator to the concentric line. The seal 11 may be of ceramic material. The klystron may have three resonators 3, 4, 5. The focusing coils 14, 15 are pushed into position over the output guide 10 and the diameter of members 1, 10, 12 can all be the same so the coils 14, 15 can be a sliding fit over them, to minimise the diameter of the coils. The collector has a cooling jacket. In a modification, Fig. 2 (not shown), the X-ray shield is surrounded by a conductive casing which forms the inner conductor of the concentric line. The collector is watercooled by giving it a jacket traversed by cooling liquid and a space is allowed between the X-ray shield and its conductive casing to allow for differential thermal expansion, a pipe from this space communicating with the exterior to remove occluded gasses during manufacture. In another form, Fig. 3 (not shown), the casing surrounding the X-ray shield again forms the inner conductor of the concentric line-coupling which is an extension of a concentric line and the collector has a cooling jacket having a partition to cause the liquid to flow from the inlet downwardly and then upwardly to the outlet.

Abstract: 540,944. Thermionic valves. BULL, C. S., and HILL, S. April 4, 1940, Nos. 6077 and 7724. [Class 39 (i)] In a thermionic valve the control electrode CG is at such a negative potential that the anode current is exponentially related to the potential of the control electrode and the electron emission which reaches the control electrode forms a high proportion of the anode current; the input power absorbed at the control electrode at high frequency is thereby reduced as relatively few electrons are returned to the cathode. In one form an additional electrode AG, Fig. 2, is inserted between the cathode and control electrode and is at a potential in the range + or - 2 volts of the cathode potential In another form the emissive surface of the cathode C, Fig. 3, is restricted to a surface bounded by the angle AB; it also need not extend the whole length of the cathode. A screen grid SG is placed with turns only on the use side of the cathode as described in Specification 534,208; the emitter is shown in Fig. 2 applied to an electron multiplier as set forth in that Specification. Sizes of one construction are given. Specification 452,372 also is referred to.
