Portable Welding Apparatus.—Inorder to facilitate womens work in the repair shops of theOrleans Railway at Paris, a practical portable oxy-acetylenewelding apparatus has been introduced. It consists of theusual cylinder of oxygen, filled under a pressure of 10 kilos,and the acetylene reservoir, these being mounted on a two-wheel wagon which can be easily moved from place to placeeven by a young girl. Flexible tubes several yards long con-nect the gases with the blowpipe, which is provided with thecustomary safety arrangement. It has been found that withthis apparatus a woman worker is able to do a multitude ofsmall soldering jobs with great rapidity and a minimum offatigue.—Srieiilifir . riintn Colyright by Vvdcrzvooil ■*r LUtdcrwood, N.
