Title: An improved superheterodyne radio receiver
IPC: H03J7/04
Filed: 1937-10-19
Abstract: 503,876. Thermionic valves; valve circuits for wireless reception. COLE, Ltd., E. K., and BRADFIELD, G. Oct. 19, 1937, No. 28420. [Classes 39 (i) and 40 (v)] In a superheterodyne radio receiver utilizing a local oscillator and mixer valve the valve is caused to provide one or more electron beams, which together constitute an electron stream, and the valve has grids and electrodes so situated with respect to the beams that the output to different electrodes may be varied by controlling the bias on certain other electrodes while maintaining the stream substantially constant in intensity, and potentials applied to grid for deflecting the electron beams are used for effecting automatic frequency control of the local oscillator circuit. Input is fed to the grid g11. Electrons from the cathode k are focused by grids g1, g2, which are at high and low potentials respectively, pass through g3 at a low fixed potential, and are deflected by the grid g4, to which automatic frequency control voltage is applied, so as to be affected by either g6 or g7, after having been accelerated by g5. The grid g9, acting as the anode of a local oscillator circuit L1, is coupled at L2 to a circuit R, C, C1, C2, to which the grids g6 and g7 are connected in such a manner that g6 and g7 are in phase quadrature, and g7 is in phase opposition to g9. Thus as the voltage on g4 is varied the reactance of the valve and the tuning of the oscillator vary. A further accelerating grid g8, is provided, and grids g10 and g11 which respectively accelerate and retard the electrode so as to provide a virtual cathode, the current from which is modulated by g11 passes through screen grid g12 before it reaches the anode. The valve thus acts both as oscillator and mixer. An automatic volume control potential may be applied to the grid g11. The grids g3 and g5 may be omitted.

Title: Improvements relating to automatically varying series resistances for use with alternating current
IPC: H02H1/00
Filed: 1929-09-23
Abstract: 337,907. Ferranti, Ltd., and Porter, G. L. Sept. 23, 1929. Current and pressure meters; frequency meters ; contacting -solid resistances; sets of resistances.-In order to increase or decrease, as required, the response of an alternating-current instrument to small changes of voltage, there is connected in series with the winding c, Fig. 1, of the instrument or relay a resistance comprising two oppositely connected metal rectifiers a, b, as described in Specification 309,514, the value of which resistance rapidly falls with increase of current. In a modification, Fig. 2, an instrument or relay has two oppositely-connected windings d, e, the current in the winding c being controlled by a constant resistance f and that in the winding d being controlled by a variable resistance a, b as described above. The resultant flux follows a curve as shown in Fig. 3, having a maximum value in one direction at the point m at which the ampere-turns of the windings d, e are increasing at the same rate. By choosing optimum values of resistance and turns, this portion of the curve can be made approximately horizontal for a range of voltage corresponding to that occurring on a supply system. An instrument of the induction type, or other type sensitive both to frequency and current, will therefore act as a frequency indicator. If an element operating on the decreasing portion of the curve shown in Fig. 3 is mechanically opposed to one having a rising characteristic as shown in Fig. 1, the resultant torque varies very rapidly with change of voltage, passing through a zero value at the voltage at which the opposed torques are equal. Such an arrangement is suitable for a relay for maintaining constant the voltage of a system. In another modification a double winding as described above forms one of the windings of a dynamometer, which in consequence has no torque at the critical voltage and torques of opposite sign for voltages above and below this value. A similar result may be obtained by connecting two of the above-described variable resistances in opposite arms of a Wheatstone bridge connection, the other two arms being constant resistances. One pair of opposite points are connected to the supply and the other pair to the winding of a dynamometer.

Abstract: 897,242. Variable-speed gearing. GRUBB PARSONS & CO. Ltd., HOWARD. July 22, 1960 [Aug. 27, 1959], No. 29341/59. Class 80 (2). [Also in Groups XIX, XXXV and XL (b)] A spectrometer for recording infra-red and other spectra against a linear wave-number scale on a moving chart comprises means to traverse the spectrum across a slit so that radiation of wavelength # emergent from the slit is incident upon an electric detector whose output signals are recorded on the chart and means for driving the chart in non-linear correspondence with the traversing means according   to the law 1/#<SP>2</SP>. d#/dt, where d#/dt is the rate of change of wavelength. When d#/dt is constant, the non- linear speed correspondence of 1/#<SP>2</SP> may be achieved by a gear and friction-drive train driven at constant speed to produce an output 1 speed proportional to -, where S is a varying S<SP>2</SP> distance in the train made proportional to #. A synchronous motor 15, operating in correspondence with the traversing means, rotates via gears a screw-threaded shaft 14a through a threaded bore in a stationary member 20. Fixed to the shaft is a driving-wheel 21 which drives by friction a disc 20 (the distance along a radius of disc 20 between its centre and the point of contact with wheel 21 being S) whose rotation is transmitted to a cylinder 28. This is in frictional contact with another wheel 22, situated a fixed distance along the shaft from wheel 21 and free to rotate on the shaft which transmits the drive to another disc 29 directly coupled to the drum 31. The distance along a radius of disc 29 traversed by the point of contact with wheel 22 is also S and all axes of the frictional elements are coplanar. The disc 29 thus rotates at a speed proportional to 1/S<SP>2</SP> as   does the recording drum 31 coupled to it. An electrical control system for achieving the non- linear speed correspondence is also described (see Group XXXV).
