Abstract
<PICT:0441435/III/1> <PICT:0441435/III/2> In a still comprising a cylindrical shell 5 and a domed-shaped bottom 3, the peripheral edge 4 of the latter is secured to the lower edge of the still wall by welding 7 in the acute angled annular channel afforded between the edges or parts on the inside of the still. The lower edge of the wall may be chamfered to suit the curvature of the bottom. In a modification, the bottom is provided with a narrow flat lip 4, Fig. 3, outward from its centre and at right angles to the plane of the wall, welding being effected along the line of contact between the upper face of the lip and lower edge of the wall. The dome-shaped top of the still is also directly welded to the still wall.
