Filed: 1948-09-27
Abstract: 651,612. Electric welding. BRITISH FEDERAL WELDER & MACHINE CO., Ltd., and TRIBE, T. F. Sept. 27, 1948, No. 25116. [Class 83 (iv)] In a welding-machine, particularly a roller seam machine, the electrodes 30, 31 and transformer 16 are supported by a common mobile framework 15 which is itself supported from a fixed framework 11 by a spring-loaded pressure pad. The framework 15 includes a platform 19 in the underside of which are housed a nest of springs 20 which bear on the lower member 21 of the pad, and in the upper side of the platform 19 are housed springs 22 which engage the upper member 23 of the pad. The pad members 21, 23 are connected by a central rod 24 and are suspended by an adjusting screw 12. A pressure reading is given by a pointer 42 which is connected by rod 40 and linkwork 41 to the pad member 23. Guide rollers 17 engage vertical posts to ensure accurate movement of the machine. In operation the weight of the machine is carried by the pad member 21 through the springs 20 and when the electrodes 30, 31 initially engage the work they exert no pressure until the screw 12 is actuated to depress the pad member 21, thus increasing the pressure on the work up to the dead weight of the machine. Further depression causes the pad member 23 to engage the springs 22 and exert an additional resilient pressure on the work which latter may be a tube to be seam welded.

Title: Improvements in and relating to phase balancing systems
IPC: H02J3/26
Filed: 1953-09-16
Abstract: 738,453. Phase-changing. GENERAL ELECTRIC CO. Sept. 16,1953 [Sept. 17, 1952], No. 25636/53. Class 38 (2). In a 3-phase to single-phase converting system in which the 3-phase supply is balanced by connection of a capacitor and an inductor respectively across the remaining phases, the values of these reactances are automatically controlled in accordance with the current and/or voltage in the loaded phase. The load is connected across phases 2 and 3, and a saturable reactor R across phases 1 and 2. The reactor has a constant bias winding 12 opposing a control winding 11 which is connected across one diagonal of a full-wave connected bridge of grid-controlled vapour-filled rectifiers 5, 6, 7, 8. The rectifiers are controlled in accordance with the magnitude of the current in the single-phase supply line, measured by transformer 15, plus the voltage of the loaded phase measured by transformer 17. An increase in line current, or a drop in phase voltage due to increased loading, reduces the output of the rectifiers 5 ... 8 and the bias winding 12 causes the effective saturation to increase so that the reactor R increases its lagging current. The capacitor C is effectively shunted by reactors 9, 10 and the rectifiers 5 ... 8, so that reduced current through the rectifiers increases the leading current due to the capacitor. In a modification, Fig. 2 (not shown), separate sets of rectifiers control the saturable reactor and the capacitor. In a second embodiment, Fig. 3 (not shown), the reactor and capacitor are connected to the three-phase system by a step-down transformer, and the load (an electric train) by a Scott-connected transformer. The load may be supplied from either of two phases of the supply and a relay automatically changes over the positions of the balancing reactor and capacitor.
