Patent FR-2229494-A1 (FR)
Title: Tandem submerged-arc welding using plasma-arc preheating - giving increased welding speeds combined with increased penetration
IPC: B23K9/18
Filed: 1974-05-02
Abstract: Although the use of electrodes in tandem increases the speed of seam-welding by submerged-arc, the increase is restricted by inadequate penetration. To overcome this problem, a plasma burner is located on an adjustable mounting ahead of the first electrode at a distance of 30-300mm (pref. 100mm); the current supplied to the plasma burner is pref. 70-800A degrees. The pref. arrangement consists of mounting the plasma burner and e.g. three electrodes in tandem on a combined holder which moves along the seam being welded, the plasma-arc being used to heat a zone narrower than the width of the seam to a temp. between 1000 degrees C and the m. pt. of the metal being welded. Instead of the plasma-arc, a tungsten inert-gas arc can be used. In an example with no preheating, three electrodes in tandem with total current of 2800A and welding speed 1.8 m/min. gave a penetration of 8mm.

Title: Differential drive for gas turbine locomotives - uses oil pump effect to prevent reverse rotation using three meshed pinion pairs
IPC: B61C9/30
Filed: 1974-07-16
Abstract: The differential gear employs sun and planet pinions of relatively small dia. which under high torque can cause reversal of rotation of one of the shafts, in differentials of this type. This is obviated by the supply of oil through a hole in the central shaft which is fed to the space between meshing planet gears. When relative motion occurs between these pairs the oil supplied from the central shaft is pumped across the gears creating a pressure load on the gear teeth and preventing reverse rotation of either shaft.
