Title: Improvements in or relating to electro/acoustic transducer arrangements
IPC: H04R19/04
Filed: 1946-07-22
Abstract: 622,830. Valve amplifying circuits. AIRMEC LABORATORIES, Ltd., (formerly P.R.T. LABORATORIES, Ltd.), SOLLEY, B. J., and ROBERTS, P. W. July 22, 1946, No. 21865. [Class 40 (vi)] [Also in Group XXXIX] An electro-vibratory transducer such as a capacity microphone is coupled to a cathode follower amplifier between the control grid and the common input and output terminal of the stage, the polarizing potential for the microphone being provided by a grid-leak resistor connected between the grid connected terminal of the microphone and a point at a suitable difference of potential from that of its other terminal. In this way increased sensitivity and an improved frequency response are obtained. The Figure shows a capacity microphone 16 coupled to a cathode-follower pentode amplifier stage, the grid-leak resistor 19 being connected to a tapping point on the cathode load resistor so that correct biassing is obtained for the valve and the voltage across the cathode resistor 15 supplies the necessary polarizing potential to the microphone. Under these conditions the effective input resistance of the stage is very high and the effective input capacity very low. In a modification, Fig. 2 (not shown) the terminal of the microphone which is not connected to grid is connected to the positive high-tension supply terminal. In a further modification, Fig. 3 (not shown), the microphone is connected between the control grid of the valve and the earthy end of the cathode load resistor and the grid-leak resistor is returned to the positive high-tension supply. The apparatus may be used for measuring the average roughness of a surface, one electrode of the transducer being fixed and the other moved by a feeler or stylus in engagement with the surface under examination. A high slope H.F. pentode may be used in the cathode follower stage.

Title: High frequency electric wave apparatus
IPC: H03B9/01
Filed: 1935-08-02
Abstract: 450,280. Tuned circuits ; wireless transmitting and receiving apparatus; thermionic valves. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Potter, R. K. ; 5, Pine Avenue, Madison, Morris, New Jersey, U.S.A.) Aug. 2, 1935, No. 21954. Convention date, Oct. 4, 1934. [Classes 39 (i), 40 (iii), and 40 (v)] The tuned circuit of a short-wave generator or amplifier consists of a tank-like structure formed as a re-entrant surface of revolution, e.g. a toroid, which is broken to form a circular gap with adjacent opposed flanges constituting capacity elements. A modified form of tank structure completely encloses the amplifying or generating valve. Fig. 5a shows two tanks A, B arranged as grid and plate circuits respectively of a generator, back-coupling being provided by a condenser connected between plate and grid. When used in a Colpitts oscillator circuit, the tank has a third insulated plate d, Fig. 6a, interposed between the capacity elements a, b, the three elements being connected to plate, grid, and cathode respectively. For a Hartley oscillator, the filament connection is taken to an intermediate point M, Fig. 7a, of the inductive part of the circuit by radial wires or by a disc. The tank may be entirely disconnected from the valve, and may be coupled to the grid and plate circuits by wire loops extending through the gap into the tank interior, Fig. 8a (not shown). The valve may be housed within the tank, Fig. 9a (not shown). In Fig. 9c, the tank is of cylindrical form with tubular axial openings X1, X2 through which leads are taken from the bias and plate batteries to the valve which is housed within the tank. The cathode is connected to the tank and its leads are taken through a tubular opening X3 in the curved wall. The tuning-condenser C3 is also within the tank and is connected between the axial tubes X1, X2. The circuit shown is of the Hartley type, but may be of Colpitts or other type, Fig. 9b (not shown). In Fig. 11a, the tank is divided by a partition x parallel to its end-plates, and its central portion G forms the grid of the valve. The cathode F and anode P arc connected to axial rods which carry the supply current and project into the tubular openings X1, X2 in the tank walls. The electrodes are enclosed in a glass envelope E. One half of the tank forms a tuned grid circuit, and the other a tuned circuit between anode and grid, and tuning is effected by making the tank of telescopic form, or by sliding adjustment of hemispherical shells S1, S2. The circuit may be employed as an amplifier with concentric conductor transmission lines TL1, TL2 used as input and output circuits. The grid and anode may be of cylindrical form. When the arrangement of Fig. 11a is used as an oscillator, back coupling may be effected by providing apertures a, a<1>, Fig. 13b, in the partition X and by mounting the grid in a disc I which is adjustable relatively to the partition X to afford variation in capacity back-coupling.
