Title: Improvements in or relating to null balance electrical measuring systems
IPC: G01R17/02
Filed: 1954-10-22
Abstract: 760,455. Transformers. LINK AVIATION, Inc. Oct. 22,1954 [Oct. 23, 1953], No. 30493/54. Class 38 (2). [Also in Group XXXVI] In a null response circuit of an A.C. balancing system, the unbalance voltage is coupled to the null indicator over a transformer wherein the primary is shielded from the secondary by a metallic electrostatic shield and the secondary is shielded from all other transformer elements by a similar earthed shield, a terminal of the primary winding being connected to the primary shield through a cathode follower circuit of unity gain and high impedance; whereby stray capacitance couplings occasioning false nulls are minimised. Fig. 1 shows two identical potentiometers 10, 20 forming opposite arms of a bridge and energized between earth and an A.C. source E. The sliders 11, 21 are interconnected by the primary of a toroidal transformer (Fig. 2) wherein a ferromagnetic torus 34 is wound with primary 31 covered by an electrostatic shield 35 wound of copper strip whose ends are insulated from each other and by an insulating layer 40 over which is wound a similar shield 37 and the secondary winding 32, which is connected across a null indicator M. Shield 37 is earthed, and shield 35 is connected to the output of a unity gain cathode follower amplifier 15 energized from terminal 12 of the primary winding connected to slider 11 so that the difference of potential between primary 31 and shield 35 is substantially zeroized and no appreciable stray capacitance current will flow therebetween. Similarly, shield 37 ensures that no appreciable stray capacitance current flows between secondary 32 and electrostatic shield 35. The only voltage appearing in secondary 32 is thus that magnetically induced from primary 31, so that a sharp null is obtained at balance. The device is applicable to any A.C. null determining system, e.g. for servomotor control, and inductance, capacitance, resistance, or frequency bridges, while the cathode follower may be replaced by two feedback amplifiers in tandem.

Abstract: 1,002,657. Control systems for resistance welding. SQUARE D. CO. Aug. 6, 1963 [Aug. 6, 1962], No. 30953/63. Heading H2H. Operation of resistance welding apparatus is controlled by a voltage signal which is representative of the changes which occur in the interface resistance between the members being welded thereby ensuring a . uniformly high quality of the weld. A welding timer 20 is arranged to provide a signal to a controller 22 which in turn provides suitable signals to a pair of reversely connected ignitions 24, 26 which control the welding current supplied to welding electrodes 12, 14. The timer 20 also supplies certain signals A, B, C, L, M, R to a detector 10 which also receives signals D, E, F, G, H, J, the detector 10 supplying an output K to the welding timer 20 which thereby controls the welding process. The signals A-R from the timer 20 control the squeeze, hold, weld and OFF periods of the welding process whereas the signals D-J are used to control the apparatus during the welding period. A signal representative the voltage across the electrodes 12, 14 is supplied to the detector 10 at terminals D, E, whereas terminals F, G receive a signal from a transformer 42 which signal is indicative of variations in the welding current flowing between the electrodes 12, 14. A further signal dependent upon the flow of welding current is fed to terminals H, J of detector 10 from a transformer 54. The detector 10 comprises a plurality of transistors and NOR circuits (Fig. 2, not shown) wherein the signal A is delayed so that the operationof the detector 10 is not influenced by transient voltages. The signal D, E from the electrodes 12, 14 is modified by the signal F, G thereby providing a signal compensated for changes in welding current and thus to be more nearly representative of changes in the interface resistance. The signal H, J from the transformer 54 is arranged to energize a pulse generator so as to provide an output pulse during the periods of maximum welding current flow, the compensated signal representing the interface resistance and the output pulse together controlling the NOR circuits of Fig. 2 (not shown) to provide the output signal K which controls the welding process.
