Abstract: 762,782. Control systems for resistance welders. GENERAL ELECTRIC CO., Ltd. Jan. 28, 1955 [Jan. 28, 1954], No. 2660/54. Drawings to Specification. Class 38 (4). The periodic switching on and off of the welding current, in an A.C. welding system in which the current flows intermittently, is controlled by a multivibrator locked to the A.C. mains and preferably of the asymmetrical type so that the number of cycles, or half cycles, during which current flows may be made different from the number of cycles, or half cycles, during which the current is interrupted. In one arrangement the welding transformer, in series with an adjustable current regulating resistor, is supplied over a pair of normally non-conducting and back-to-back discharge tubes. The multivibrator, which is locked to the mains supply by a peaking transformer, causes, during one part of its cycle of oscillation, conduction of a valve arranged in shunt with a condenser supplying hold-off bias for the leading tube of the back-to-back pair. This bias is thereby removed and the pair of tubes conduct, causing energization of the welding transformer during this portion of the multivibrator cycle. Over the other part of the oscillation cycle the valve is rendered non-conducting, so that the discharge tubes are held-off and the flow of welding current interrupted.

Abstract: 632,199. Superheterodyne circuits. PHILIPS LAMPS, Ltd. Jan. 29, 1947, No. 2768. Convention date, Feb. 15, 1944. [Class 40 (v)] Improvement in the tracking of a superheterodyne receiver with ganged tuning controls is obtained by means of a parallel fed oscillator circuit with the normal series and parallel condensers, the supply voltage to the anode being fed via a resistance connected in series with a parallel combination of an inductance and a condenser. As shown in Fig. 1, the oscillatory circuit 1 is included in series with a blocking condenser 2, in the anode. circuit of a triode oscillator 3. A second oscillatory circuit constituted by the inductance 10 and condenser 11 is connected in series with the supply resistor 4. This circuit is adjusted to resonate at the oscillator frequency when the receiver is tuned to a frequency, normally in the centre of the medium waveband at which the tracking error is zero. The impedance of circuit 10, 11 is variable with frequency and by this means the deviation from the required difference frequency is reduced for the tuning range. Specification 424,714 is referred to.
