Abstract: A transferred type plasma torch comprises a body containing and rigidly interconnecting; a bushing having an internal constricted surface, a collet attachment mounted in the bushing, an electrode mounted in the collet attachment, a nozzle tip disposed coaxially of the electrode at the tip, and a centrally bored end cap screwed in the end of the bushing and having an internal countersunk surface. The collet attachment is composed of a cylindrical collet having a spherical flanged portion and a collet chuck having a spherical flanged end portion and mounted in the collet, the spherical flanged portion of the collet being received in the internal constricted surface of the bushing, the spherical flanged end portion of the collet chuck being received in the internal countersunk surface of the end cap. The spherical flanged portion of the collet and the spherical flanged end portion of the collet chuck are so designed that they have the same center of curvature.

Abstract: A 2'-halopenicillin compound is prepared from a penicillin-1-oxide compound by the action of an acid halide in the presence of a base. The product on heating rearranges to a 3-halo-3-methylcepham compound which itself gives a 3-methyl-3-cephem compound on further heating. A 2'-halopenicillin compound gives a 3-methyl-3-cephem compound on heating. The 2'-halopenicillin compounds, 3-halo-3-methylcepham compound and 3-methyl-3-cephem compounds are antibacterials which are also useful as intermediates for the synthesis of other penicillins and cephalosporins.
