Title: Improvements in radio direction finding apparatus
IPC: G01S1/02
Filed: 1940-07-17
Abstract: 542,584. Indicating-apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and MOON, J. H. July 17, 1940, No. 11820. [Class 106 (iv)] [Also in Group XL] The scale of a direction-finder comprises two relatively movable circular members I, L, the upper one I having alternate transparent and opaque sections and the lower one L having two " systems of numeration ", the numerals of one system 210, 220, 230 &c., alternating with those of the other complementary system 30, 40 &c., and being spaced apart so that one system is visible through the transparent sections of the upper member in one position and the other system in the other position. The member L is linked to the sense switch so that the scale reading is changed at the same time as the sense of the finder is changed, whereby a direct reading corrected for sense is obtained. A third transparent scale member U above the member I bears a curve C for correcting site error (e.g. quadrantal) the correct reading being given at the point where the reading edge E of the pointer P intersects the curve. When the finder is to be used at a fixed station, the members L, I are linked by a pin and slot p, s which permits the necessary relative movement, in such a way that they can be preset to take corrected true bearings, the member U being fixed relatively to the N and S of the station. The member L may engage click-pins Cl, C2 whereby correction may be made for the magnetic variation of the site. When the finder is used on a navigable craft, the member U is fixed relatively to the fore and aft line of the craft, and the member I mechanically linked through gearing with the driving mechanism of a gyro-compass, so that direct bearing readings may be obtained. Specification 509,842 is referred to.

Title: Improvements in electron multipliers
IPC: H01J43/18
Filed: 1938-04-20
Abstract: 501,316. Electron multipliers. FARNSWORTH TELEVISION, Inc. April 20, 1938, No. 11835. Convention date, April 30, 1937. [Class 39 (i)] In order to avoid interferences with emission by space-charge, the electron stream emitted by the first secondary-emission electrode is divided into two portions, which strike separate further secondary-emission electrodes and are finally received, if desired after further multplication, on separate anodes electrically connected. In the arrangement shown, an indirectly heated cathode 3 and control and screen grids 5, 6 are enclosed in a cylinder 9, the inner surface of which is coated with secondarily-emissive material. The resulting stream of secondary electrons is drawn out at both ends of the cylinder 9 by permeable accelerating electrodes 14, and strikes further secondary emission electrodes 15, the electrons being finally collected by the electrodes 14. A scheme of connections for the electrodes is shown.

Title: Improvements in or relating to control units, particularly for internal combustion engine installations
IPC: B63H21/22
Filed: 1947-05-02
Abstract: 628,296. Controlling reversing-gearing ; locking levers. THORNYCROFT & CO., Ltd., J. I., and CLARKE, F. M. May 2, 1947, No. 11877. [Classes 80 (ii) and 80 (iii)] A control lever 1 actuates both the gear change operating arm 5 of a marine, rail-car or like forward-reverse transmision and the output regulator of a driving I.C. or other engine. The lever 1 is rotatable on a shaft 2, to which the lever 5 is clamped, and carries a pawl 6. During initial movement of the lever 1 in either direction from a central neutral position, the pawl 6 is held in a recess 4a in a plate 4 on the shaft 2 by engagement of a roller 6b on the pawl with a cam edge 3a on a fixed support plate 3, and the lever 1 thus entrains the arm 5 to cause gear engagement. The end of a second arm 1b on the lever has a pin and slot pivotal connection to a rod (not shown) which is aligned with the arm 1b when the lever 1 is in the neutral position. The remote end of this rod is connected to the engine output regulator lever which is allowed by the lost motion in the slotted connection to remain in the closed position, to which it is spring-urged, during movement of the lever 1 to effect gear engagement. On further movement of the lever 1 in either direction the roller 6b leaves the raised part of the cam edge 3a and releases the pawl 6 to free the arm 5 from the lever which then controls the engine regulator only. A stop 3b on the plate 3 co-acts with the ends 4b of a cut-out on the plate 4 positively to prevent further movement of the arm 5. The regulator may be operated by the lever 1 through cam means instead of linkwork. Locking levers. The arm 5 is locked in the gear-engaged position during regulator-controlling movement of the lever 1 by a ball 12 of greater width than the plate 4 and housed in a bore 4c therein. The proud portion of the ball 12 is located in a recess 1d in the lever 1 during the gear-engaging stroke of the latter but passes into one or other of two recesses 3c on the plate 3 to lock the plate 4 thereto when the lever begins its regulator-controlling movement.

Title: Improvements relating to receivers for angle-modulated carrier waves
IPC: H03G3/28
Filed: 1946-04-26
Abstract: 612,536. Frequency modulation. RADIO CORPORATION OF AMERICA. April 26, 1946, No. 12597. Convention date, April 26, 1945. [Class 40 (v)] A receiver for F.M. carrier waves is muted when inaccurately tuned by control voltages derived from a balanced discriminator-detector, the load resistances of which are so arranged that the differential voltage is fed to the audioamplifier, and the additive voltage is applied to a control valve to reduce the gain of the amplifier. in Fig. 3, the discriminator 20 feeds a balanced pair of diode rectifiers 26, 28, each shunted by a divided resistor 52, 53; 54, 55. The audio signal is taken off across the resistors 53, 55 and is applied to the grid of the audio-amplifier 38. The D.C. voltage across the resistors 53, 55, which represents in magnitude and sign the degree and direction of mis-tuning, is also applied to the grid of the amplifier 38. If the D.C. voltage is negative, it reduces the amplification directly, and if positive it causes grid current drop in the resistor 36 and again reduces amplification. An additional or alternative control is provided by a muting-valve 57 connected in parallel with the audio-amplifier 38 with its grid 59 connected through a smoother 71 to the outer end of the resistor 52 so that the grid receives a proportion of the sum of the negative voltages across resistors 52, 55. If the set is mis-tuned, this voltage becomes less negative, the valve 57 takes current and cuts down the audio output by reducing the anode voltage of the amplifier and by diminishing the output impedance. In a modification, Fig. 6 (not shown), the valves 38, 57 are associated by a common cathode resistor instead of a common anode resistor 43. The Specification also describes a further arrangement in which each diode is shunted by an undivided resistor, and a series circuit is formed by the two resistors and the inductance 27 of the discriminator, the voltage across this series circuit being applied to the grid of the audio-amplifier 38.
