Title: Measuring weld resistance/voltage drop
Inventor: DENNING ROBERT EDWIN ARTHUR
IPC: B23K11/25
Filed: 1982-09-20
Abstract: In electric spot welding wherein sensor leads are attached to the main welding current conductors to detect the weld nugget voltage drop for welding control purposes, inductive coupling between the main welding current conductors and the sensor leads is avoided by attaching the sensor leads at positions remote from the welding electrodes. The sensor lead signal waveform (10) is shifted vertically by summing with it a d.c. voltage, so that the waveform becomes asymmetrical (22) about its base or zero voltage level, and the signal required for welding control is derived by detecting the peaks of only the half cycles of the waveform that are thereby reduced in amplitude. <IMAGE>

Patent GB-2144289-A (GB)
Title: Drift compensation
Inventor: BROWN JAMES CALLAN
IPC: H03K5/08
Filed: 1984-07-23
Abstract: A drift compensating circuit consists of a summing amplifier 35, a high gain amplifier 34 and an integrator 36, 37. The input signal 31 is converted into a train of constant amplitude rectangular pulses of alternating sign. As the mean level of the input signal 31 rises and falls relative to zero the durations of the pulses will increase and decrease in dependence thereon and the output E from the integrator 36 and 37 will depend on the relative durations of the positive and negative components. A proportion of the integrator output E, which is opposite in sign to the drift of the input signal 31, is fed back to the summing amplifier 35 and so forms a control loop 32 to keep the mean of the output close to zero. The circuit is used in a strain recorder in which recordings can be made of total strain, with and without zero correction; quasi-static wave loading components; and, if required, the slam component of wave induced strains. <IMAGE>
