Descriptions by Initials THE mania in France for the Mania J. employing a forest of Passing 1 initials when describing companies or institutions, which. .started in the early nineteen-thirties, seems to have reaChed its peak. For instance, the L.0 F I.C.A L.C.O.F is simply the distributing branch of the French Food Ministry. Mergers in the motor industry are, nevertheless, reducing the forest by equations. In the Paris public-transport world, the Soci61.6 des Transports en Commun dans A26 la Region Parisienne, having merged With the Cornpagnie du Metropolitan de Paris. does not call itself the S.T.C.R.P.C.M P., but the Regie Autonorne des Transports Parisiens.

MILD steel, aluminium and stainless steel parts made from the sheet metal can be welded freely by a new process using a gun-shaped tool. A spot weld is produced by heat from an electric arc between a tungsten electrode rInd one surface of two lapped pieces of metal; it is nicknamed "poke welding." The weld differs from resistance spot welding in that it is caused by fusion only, whereas a resistance spot weld is a result of high current and pressure applied to the electrode. The welding action is controlled by current input to the arc and the length of time that the arc impinges on the surface of the material being welded. Inert-gas shielding of the region of the weld is used, as in conventional methods.
