Abstract: 732,462. Valve circuits. SIEMENS-REINIGER-WERKE AKT.-GES. Oct. 31, 1952, [Nov. 2, 1951], No. 27497/52. Class 40 (6). [Also in Group VI] Apparatus for applying ultrasonic oscillations to a workpiece (e.g. to a human body for medical purposes) comprises an oscillation generator, a transducer and alarm means which responds when the amplitude of the oscillations applied to the transducer rises above a predetermined level thus indicating that the coupling between the transducer and the workpiece has fallen below a desired minimum value. The output from the oscillator valve V1 is applied through an automatic gain-controlling stage V2 to the parallel-connected power amplifiers V3, V4, the output from which is applied through a transformer coupling to the transducer S. A portion of the energy applied to the transducer is tapped off by the capacitative potential divider Sp and rectified by diode V6, the resultant negativepotential being applied to the valve V7. If the potential applied to the valve V7 rises above a predetermined level the relay RS is actuated and an alarm (e.g. a lamp or a buzzer) is operated. To maintain the amplitude of the oscillations developed by the power amplifier V3, V4 constant, A.G.C. is provided. The oscillatory potential across the condenser C1 in the cathode circuit of the power amplifier is applied through a voltage step-up arrangement comprising a series-tuned circuit to the diode V5, the rectified output from which is applied to the grid of the gain-controlling valve V2. In order that the output level of the apparatus may be varied the potentiometers P and switch R are provided. The potentiometers shown in the left-hand side of the figure are used to provide three different possible bias potentials for the A.G.C. diode V5 thus enabling the output from the generator to be varied. The remaining potentiometers apply corresponding bias potentials to the diode V6 to cause the oscillation amplitude at which the alarm system responds to be correspondingly varied. Stabilization of the H.T. supply for valve V1, screen-grid potential of valve V2, grid-bias potentials of valves V3, V4 and of the potentiometer supplies are provided by means of the voltage stabilizer ST.

Abstract: 271,731. Br³ckner, G. Nov. 3, 1926. Mercury switches. - " Left " and " Right " indicators for vehicles, which are raised into position by energization of an electromagnet g or h., are adapted to be automatically returned to their original positions in consequence of the steering wheel movement operating a tiltable mercury switch. As shown in Fig. 1 the rearwardly inclined steering wheel a carries two tubes b, c containing mercury. Rotation of the wheel a in one direction or the other causes the mercury in one of the tubes b, c to bridge contacts in a circuit to a coil d or e which thereupon attracts a latch i or k and allows the corresponding indicator to fall. In a modification, Fig. 4, the tubes b, c take the form of figure eights. In this case the circuit to the coil d or e is only completed as the steering wheel a is being returned into its straight ahead " position. In further modifications, the tubes b, c are joined so as to form one tube, and the arrangement may also be such that the movement of the wheel a causes a circuit to be broken instead of to be made. The tubes b, c may be mounted on a carrier rotated by means of a chain &c. from the steering wheel, and may also be mounted in one unit with the switches for operating the magnets g, h.
