In a method of manufacturing positive tube plates for accumulators a mixture containing essentially Pb and Pb compounds is filled into the tubes of the tubular pockets, which contain a lead core connected to the terminal strip, from the ends of the tubes remote from the terminal strip, until the tubes are full, whereupon the filling openings of the tubes are closed. In this method lead dust is gra...

A process and apparatus is provided for the production of nitrogen with over-atmospheric pressure by two-stage rectification of air at low temperatures. Air (1) is compressed (2), pre-purified (4, 6), cooled (33) in heat exchange with products of fractionation, and fed to the rectification device. An oxygen-enriched liquid (19) from the sump of the low-pressure stage (13) is vaporized (15) in cont...
