Title: Improved attenuator for modulated-carrier signal receivers
IPC: H03G3/22
Filed: 1939-03-25
Abstract: 526,726. Wireless receiving systems. HAZELTINE CORPORATION. March 25, 1939, No. 9428. Convention date, April 7, 1938. [Class 40 (v)] An attenuator for use in a modulated carrier receiver comprises one coupling path producing voltage at the input of an amplifier and a second coupling path, whose gain is controlled in accordance with signal strength, which injects a voltage into the cathode circuit of the amplifier in opposed phase. Signals from the antenna 10 are passed by the tuned circuit 20, 21, to the radio frequency amplifier 13 and then on to the normal superheterodyne receiver 14 - 18. An extension 40 of inductance 20 together with condenser 41 provides neutralization of undesirable capacitive coupling through valve 13. The cathode resistance 24 is not byepassed for high frequencies but the anode circuit is returned direct to the cathode for high frequencies by condenser 27. The second coupling circuit consists of valve 25 whose grid circuit is connected across the tuned input circuit and whose load circuit consists of resistance 24 which is common to the cathode circuits of both valves, resulting in a signal voltage of opposing phase being produced in the cathode grid circuit of valve 13. In order to provide control biases for valves 25 and 13, signals from the input circuit are amplified in valve 28 and passed to diode rectifier 29. The voltage generated across load resistance 32 is applied positively over filter 34, 35, to' increase the amplification of valve 25 as the signal input increases. Simultaneously an auxiliary diode 37 in valve 28 produces a voltage which is applied negatively to reduce the gain of valve 13. The circuits following valve 13 are more selective than circuit 20, 21, so that undesired as well as desired signals are included in the input to amplifier 28. A filter, or other circuit having a resistive impedance over the band of frequencies for which the circuit is to operate, can be utilised in place of resistance 24. In a modification, Fig. 2 (not shown) the amplifier 28 is dispensed with, the bias for the valve 25 being obtained from a diode coupled to its own output, while the control bias for the valve 13 is obtained from the normal A.V.C. supply in the superheterodyne receiver. In another modification, Fig. 3 (not shown), the auxiliary valve 25. is dispensed with. The cathode resistance is provided and the screen circuit of valve 13 is not decoupled for radio frequencies. An amplifier fed from the input circuit feeds a diode which developes a controlling voltage which is fed negatively to the suppressor grid of valve 13. As this bias increases negatively it causes the amplification. of valve 13 to decrease and also due to the increased screen current causes a degenerative signal to be developed across the cathode resistance. Specification 526,725 is referred to.

Abstract: 475,769. Discharge apparatus; thermionic valve circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. April 2, 1937, No. 9456. Convention date, April 2, 1936. [Classes 39 (i) and 40 (v)] A tube comprises a set of secondaryemitting electrodes adjacent the primary cathode constituting a secondary cathode system and a further set of electrodes, both sets being located symmetrically in pairs with respect to the primary cathode. The secondary-emitting set may comprise two semi-cylindrical grids made up of longitudinal wires or radial or oblique slats joined by end bridges or of sheet material longitudinally slit, the remaining portions being twisted to serve as slats. In a modification, Fig. 5, four arcuate sheets PI, P2, P3, P4 are arranged about the cathode K of a magnetron and are secondary-emissive on their outer faces. Secondary-emitting slats W may be added. A four-part anode system Al, A2, A3, A4 surrounds the sheets. Input oscillations may be applied across a two-part inner system, the output being connected across a two-part anode system. In a frequency-multiplier, Fig. 7, the input is applied to a circuit St connected across the inner system P1, P2 and, in the form shown, doublefrequency oscillations are taken from the circuit O. A positively-biassed collecting electrode system N, to which modulation signals may be applied, is provided. The axial magnetic field coil is not shown.

Filed: 1944-05-17
Abstract: 596,366. Coating metals. DAVY & UNITED ENGINEERING CO., Ltd. (United Engineering & Foundry Co.). May 17, 1944, No. 9470. [Class 82 (ii)] [Also in Group XXXVI] In a method of flowing a metal coating on a metal strip by heating until the coating just melts and then quenching, the strip, after quenching, is reheated by passing an electric current through it prior to oiling it. As shown, the strip 1 after electrolyte deposition of the coating metal passes over a roll 6 at the top of a tower 8 and under a roll 9 immersed in a water tank 10 from which it emerges to a roll 13, an oiler 14 and is then coiled. The rolls 6 and 9 may be connected to a transformer 25 to heat the strip by resistance before quenching and rolls 9 and 13 are simlarily connected to heat the strip sufficiently to dry it after quenching. The roll 13 may be situated in advance of the oiler so that a portion only of the strip is heated. The temperature of the strip is maintained constant by a pyrometric control device 41 which may control the current supplied to the primary coil of the transformer, or the generator speed or the generator field. The atmosphere in the tower may be composed of an inert gas and any steam which may be generated during quenching is removed by a hood 38.

Abstract: 1,137,713. Making spheroidal particles. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 25 Jan., 1966 [5 March, 1965], No. 9507/65. Heading B5A. [Also in Division C1] Spheroidal particles of nuclear fuel, as required for nuclear fuel manufacturing processes, are formed by mixing a powder of an oxide, carbide or nitride of uranium with sufficient binder, e.g. 10 millilitres of furfuryl alcohol with 100 gms. uranium oxide, to form a crumbly paste which, after sieving, yields particles 10 of 300 microns which are placed within a continuous particle retaining abrasive coated channel formed circumferentially around a rotor 12 as a body of revolution about an axis 13 which is at an adjustable angle to a horizontal axis of rotation 14 whereby, when the rotor 12 is rotated about axis 14, the particles 10 are carried up towards the axis 14 by frictional contact with the abrasive coated channel and roll back under gravity towards the bottom thereof and are simultaneously given a component of oscillation along the direction of the axis 14 due to the angular displacement of axis 13 with respect to axis 14. The speed of the rotor is such that the particles are not carried above the axis of rotation 14. The spheroidal particles are sieved to 300 micron diameter and these are sintered. Powdered graphite can be mixed with the powder in the paste or introduced into the channel whereby it disperses in the furfuryl alcohol and, on subsequent heating, yields a pyrolytic carbon bound graphite coating which can be further coated with pyrolytic carbon.

Abstract: 948,698. Gas-blast switches. WESTINGHOUSE ELECTRIC CORPORATION. March 15, 1962 [March 27, 1961], No. 9930/62. Heading H2B. Arc decomposition products in a gas-blast circuit-interrupter having a substantially closed gas system are removed by a filter in a metallic exhaust chamber disposed in near proximity to the interrupter contacts. In a puffer-type circuit-breaker (Fig. 1), the arc gases pass through the fixed nozzle contact 22 and non- return valve 38 into a terminal chamber 9. This gas must pass through filtering element 8 to re-enter the main chamber 5. The element 8 may comprise fine-mesh screening and activated alumina powder.
