Filed: 1923-05-30
Abstract: 200,797. Reliance Co., (Assignees of Bradley, H. L.). July 13, 1922, [Convention date]. Contacting-solid resistances; potentiometers.- A variable resistance comprises a number of contacting electrodes within a casing, in the cover of which is mounted a spring-pressed plunger engaged by an axially movable adjusting member. Two sets of electrodes may be provided, with a cam actuator arranged so that the resistance of one set increases while that of the other decreases, the total resistance remaining approximately constant. The contacting electrodes may comprise flat discs 4, Fig. 1, of graphite or other suitable material, arranged in sets 1. 2 in spaced pockets within a casing 6 of porcelain or other insulating material and mounted with the plane of the discs vertical. The cover 13 of the casing carries bushings 18 containing slidable plungers 16 which are recessed to receive coil springs 17 with their inner ends bearing against the outer end discs 5. The end discs 5 are thicker than the intermediate ones and may be made of metal with a silverplated surface. A spindle 12, rotatably mounted within a shouldered sleeve 14 supported by the casing and its cover 13, carries the cam disc 10 with its cam faces 15 bearing upon the plungers 16 and exerting pressure upon the springs 17. The cam disc is thinnest at the point 21, Fig. 3, and its thickness increases gradually to a point 22 diametrically opposite. Shoulders 19 are provided midway between the points 21, 22 and cooperate with a stop upon the cover 13, limiting the rotary movement of the cam to 180‹. To ensure that the cam remains in anv adjusted position, the inner end of the spindle 12 is provided with a bowed spring 40 held against the casing 'by an adjustable nut 41 and look nut 42. The initial pressure between the electrodes can be adjusted by screws 9 which pass through internally threaded rivets 7 holding the terminals 8 to the casing and engage the inner end discs 5. The screws can be locked in position by lock nuts 9<1>. In addition to the two terminals 8 an intermediate terminal is provided to enable connection to be made at a point between the two resistors. The cover of the casing may serve as this intermediate terminal. The rheostat may be used as a voltage divider or potentiometer.

Filed: 1924-06-17
Abstract: 218,276. Huth Ges., Dr. E. F. June 27, 1923, [Convention date]. Thermionic valve circuits; calling apparatus.- In an electric discharge device operating as described in Specification 217,230, in which a part of the discharge path is bridged by a resistance, a variation of this resistance is caused to effect a sudden and permanent reduction in the resistance of the discharge path. Fig. 5 shows the application to a receiving circuit in which the resistance in parallel with the part a, g of the discharge path a. k comprises a fixed resistance o in series with the inner resistance path n, t of a thermionic valve. Incoming signals affect the potential of the grid i and vary the resistance of the valve, and, by adjustment of the voltage applied to the anode a or of the heating of the filament k, or of the resistance of the path n, t e.g. by potentiometer control applied to the grid i, may be arranged to cause a sudden drop in the resistance of the path a, k which remains stationary until the filament or plate voltage is reduced. This arrangement may be employed to actuate distant apparatus to give a call which will operate continuouslv until filament or anode batteries are disconnected. The anode supply may be alternating or pulsating or oscillatory. In the latter case a circuit l, p may be connected across the anode filament path a, k through suitable chokes d, and the resistance of the path a, k will be restored to normal on the cessation of a signal owing to the fluctuation of the anode potential, and the anode current will be controlled in rhythm with the incoming signals. These ar. rangements may be used for telegraphic or telephonic reception or for the remote control of apparatus. Fig. 6 shows the application to a telephone transmitter in which the oscillations in the anode circuit are microphonically modulated through a control valve inserted as a variable resistance in the shunt path of the discharge device. The application to a high frequency receiver in which a rectifying or detecting device of a known kind is used is also described.
