Filed: 1946-05-17
Abstract: 630,132. Valve amplifying circuits. JOHNSON, L. R. J., HOLLOWAY, D. G., and WHITE, E. L. C. May 17, 1946, No. 14911. [Class 40 (vi)] The distributed shunt capacity of an impedance in the negative feedback path of an amplifier is neutralized by applying an additional feedback voltage to a screen surrounding the impedance or to one or more different points on the impedance. The screen may be a resistance winding or a semi-conducting member. As shown, the output of a television transmitting tube 6 is fed to a four-stage amplifier 7, 8, 9, 10 across resistances R3, R4 which have distributed shunt capacity 2. Part of the output derived from the cathode follower 10 is fed back from a tapping on the load resistor 35 to the low potential end of resistance R4, while a portion of the feedback derived from potentiometer 38, 39 is applied via condenser 5 to the junction of resistances R3, R4. The resistance 39 may be shunted by a condenser 40 to compensate for phase shift in the feedback loop. The additional feedback may be applied to a screen surrounding the feedback impedance from one end to a point of substantially zero signal potential, at which point the screen is earthed, Fig. 1 (not shown).

Class 98(1) In a shutter having an axially movable release button and a locking device for said button, a groove or grooves corresponding to the rest, or rest and release, positions of the button is or are engageable by a lever which is resilient transversely of the button and is adapted to be moved towards and away from the button by an actuating element which is rotatable concentrically of the button. As shown the shutter button 1 is retained in the shutter housing 3 by a collar 4 engaging a rotatable sleeve Z which itself is retained by a collar 6, and is prevented from falling into the housing by shutter operating mechanism engaged by the fork 5. One arm 13 of a hairpin spring on a fixed pin 14 bears against the outer surface of the sleeve by engaging in a groove 11 therein while the other spring arm 12 passes through a segmental recess 15 (Fig. 2 not shown) to lodge in one or other of the grooves 16, 17 in the button to latch it. On rotating anticlockwise a knob 8 freely mounted on the sleeve by a screwedon bush 9, the movement being limited by a projection 20 on the casing engaged in a recess 19 in the knob, a spring clip 18 located in a recess in the knob and having a projection 24 engaging in a notch in the sleeve drives the sleeve to cam the spring arm outwardly to free the button. To retain the knob in this position, freeing the button, the sleeve may be provided with a pair of vertically spaced notches in either of which the turned over end of the spring 13 engages.
