Title: Improvements in or relating to automatic frequency control systems for oscillation generators
Inventor: MARCH ROY COLLINS
IPC: H04N5/12
Filed: 1959-11-10
Abstract: 877,754. Automatic frequency and phase control systems. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. May 30, 1960 [Nov. 10, 1959], No. 38055/59. Class 40(5) An oscillator O after subdivision in frequency at DM (e.g. by 405) synchronizes a pulse generator W3, W4 normally producing broad pulses which are applied to a phase detector CM6 together with a reference wave, e.g. mains frequency, from a switch M, whose output, after amplifying at CM12, phase locks and stabilizes the oscillator O with respect .to the reference frequency from M. But, near to stabilization being established, a transistor switch W5 is rendered conductive by the reference wave M to introduce a circuit element W7 into the pulse generator circuit and generate narrow pulses, producing a fine control of the phase insensitive to temporary disturbances. To this end a phase advance circuit CM2, W14-16 is used such that when pulses concide with a unidirectional sloping and control flank of the reference wave M at the phase detector CM6, the transistor switch W5 is then conductive due to M being negative. Further, a rectifier W11 and capacitor W10 rectify the reference wave M to counteract a normal blocking (positive) bias on the base of the transistor W5 and delay the generation of narrow pulses for a period after switching on the control system, the rectified bias being limited to a maximum value by a rectifier W17. As shown, the phase detector CM6 ceases to short circuit the input wave M and passes current to an output circuit CM7 only when positive pulses render transistor CM6 non-conductive. Variable resistor CM8 adjusts the free running frequency of oscillator O, and diode CM14 compensates for temperature changes. The voltage output of CM12 controls the frequency and phase of oscillator O by varying the collector (base capacity of oscillator O). The oscillator O may be part of a television transmitter, and run at twice line repetition frequency. It may alternatively be stabilized relative to synchronizing line pulses applied at L by applying it, subdivided in frequency by 2 at DL, to a phase detector CL6 with output free from short-circuiting only when line pulses are applied to the base, and after amplifying at CL12 applied to vary the base bias and base/collector capacity of oscillator O. Resistor CL3 adjusts the free-running frequency of oscillator O and stabilized phase, and inductor CL5 increases the frequency range of locking.

Abstract: 303,371. Dubilier Condenser Co. (1925), Ltd., (Assignees of Linke, J.). Dec. 31, 1927, [Convention date]. Vacuum tubes.-Valves for wireless receivers employ a discharge through an ionized gas without the use of any heated electrode. The main anode of an amplifying valve I is connected to a second anode Y through a condenser Z and through the secondary of a transformer 3 of which the primary is in the grid circuit of the valve; this arrangement is stated to improve the amplification. The Specification as open to inspection under Sect. 91 (3) (a) includes also the following subject-matter : The gas filling may consist of neon or a mixture of neon or other inert gas with calcium, and the discharge through it is obtained solely from the usual H.T. sources of about 100 volts. The cathode may comprise a flat plate C, Figs. 1, 2 and 5 (Cancelled), which may have a projection of another metal as shown in Fig. 1 (Cancelled), or a smooth or corrugated cylinder C, Fig. 3 (Cancelled), and the anode may comprise a flat plate B, Fig. 2 (Cancelled), or a metal or carbon rod B, Figs. 1, 3, and 5 (Cancelled). Control grids may be arranged in the usual manner, as at D, Fig. 1 (Cancelled), or two smooth or corrugated grids may be arranged concentrically, as shown at D, Fig. 3 (Cancelled), or they may be placed end to end. A two-stage valve is shown in Fig. 4 (Cancelled), the grids D enclosing the anodes B and the cathode C separating the grid and anode of one stage from those of the other. In the construction shown in Fig. 5 (Cancelled), the glow discharge is produced between an anode B and the cathode C, and a second anode E is arranged as closely as possible to the glass to prevent ionization of the glass and so to increase the efficiency of the grid D.

Particulate solid material to be separated, such as coal, is passed to a thermal drier 10 and then to a dry separator 14, the finer and lighter particles being removed from both the drier and separator by gas entrainment. As shown, the coal is fed by a screw conveyor 11 on to a fluidized bed of the drier which is provided with a furnace 18 supplied with fuel through a pipe 19; the particles become fluidized and dried by means of hot gases which pass through a perforated bed plate 12. The fluidizing medium may by the products of combustion or air. The particles then pass down an outlet 13 to one or more separators 14 each provided with one or more perforated vibratory tables 15; if desired the particles may be screened before entering the separators. In the separator shown, separation is made by means of the vibratory motion of the bed plate and an upward current of air which causes the particles to be fluidized. A fan 16 is used to introduce air into both the drier and separator, the finer and lighter particles being led from the drier and separator to a cyclone 17. Fine coal is withdrawn from the bottom of the cyclone and the clean fraction through an outlet 24. If desired, separate fans and cyclones may be employed and, instead of air, an inert gas may be employed in a closed circuit. Control dampers 22, 23 and 13a regulate the air flow. In alternative forms of the invention, the dry separator may be spiral, utilize jump plates or employ beds of marbles, sand or magnetite.
