Abstract: A vertical hollow tube closed at its top end has a first hole in its side wall adjacent its top end and is filled with gaseous deodorizer under pressure. A vertical hollow cylinder closed at its top end and open at its bottom end has a second hole in its side wall.

Abstract: The present pipe elbow includes at least two straight pipe sections joined together along a Y-seam, for example by welding. The Y-configuration of the seam is such, that the three limbs thereof all have the same length, whereby these limbs meet at a point off center relative to the central axis of the pipe. The elbow is formed by making a straight cut at right angles toward the longitudinal axis of the pipe and slightly through said longitudinal axis and by further cutting the straight pipe at acute angles so that second and third cuts meet the first cut at said off center point. These cuts result in wedge segments which fit exactly into the space between the arms of the Y-configuration when the pipe edges are joined along the leg of the Y-configuration. Thus, the present process does not produce any waste whatsoever.
