Title: Improvements in or relating to tubes
Inventor: DAVIES JARED MARSHALL
IPC: C22F1/00
Filed: 1965-03-01
Abstract: The structure of a butt welded metal tube is homogenized by cold reducing the wall of the tube by planetary ball swaging, and heat-treating the tube to recrystallize the structure.  In an example, an 18/8 Ti stabilized stainless steel tube, produced by butt welding flat strip, is swaged to reduce the tube wall thickness by 14-32%, the tube annealed at 1050 DEG C. for 15 minutes and then oil quenched.  The resulting structure includes uniform equaxial austenite grains with a distribution of ferrite. A total reduction of 55-65% followed by heating at 800 DEG -950 DEG C. for 5 hours reduces the grain size from about 30m  to less than 7m .  In another example, a 20% Cr, 25% Ni, Nb stabilized stainless steel tube is heat-treated in argon at 1050 DEG C. and oil quenched.  In a further example, a tube of zircalloy 2, of composition 1.38% Sn, 0.084% Cr, 0.043% Ni, 0.071% Fe, balance Zr, is produced by electron beam welding, any longitudinal welds being cold reduced by 45-55% and circumferential welds by 35-40%. After heat-treatment at 820-860 DEG C. in a protective environment such as vacuum or He or Ar for 1 hour the physical properties of the tube are constant throughout.  The invention is also applicable to Ni-Fe alloys, and alloys of Nb, Ti and Ta.

Title: Manufacture of sulphonamido-derivatives
IPC: D21H17/09
Filed: 1942-06-26
Abstract: Sulphonamido derivatives which may be used as assistants in the textile leather or paper industries or for combatting pests are prepared by treating a sulphonamide which contains at least one hydrogen atom attached to the nitrogen atom of a sulphonamido group and is free from primary carboxylic acid amide groups and from primary or secondary amino groups with an aldehyde- or ketone-bisulphite compound in the absence of solvents and, if desired, in the presence of a small quantity of a secondary amine as a reaction accelerator.  Sulphonamides mentioned include aliphatic, cycloaliphatic or aromatic sulphonamides such as hexyl-, octyl-, dodecyl-, hexadecyl-, or octadecyl sulphonamides and derivatives of these compounds which are mono-substituted such as acylated or alkylated in the sulphonamido group.  Such substituted compounds include N-stearyl-p-toluene sulphonamide, cymene sulphonamides monosubstituted in the sulphonamide group by the residue of coconut fatty acid.  The preferred bisulphite compounds are water-soluble formaldehyde-bisulphite compounds, although acetaldehyde- or acetone bisulphite compounds may also be used.  In examples.  (1) sodium formaldehyde-bisulphite is reacted with paratoluenesulphonamide at 160-165 DEG  C.; (2) cymene sulphonamide is reacted with sodium formaldehyde bisulphite in the presence of a small amount of diamylamine at 160 DEG  C.: (3) N-stearyl para-toluenesulphonamide is reacted with sodium formaldehyde bisulphite in the presence of diamylamine at 140-190 DEG  C. in stages; (4) technical tetra-hydronaphthalene sulphonamide, sodium formaldehyde bisulphite are reacted in the presence of diamylamine at 160-165 DEG  C., (5) a cotton fabric is printed with a printing paste which contains inter alia the product of example (1).  The compounds of the invention which contain an aliphatic or cycloaliphatic residue of high molecular weight posses surface activity and may accordingly be used as wetting, washing, foaming, emulsifying, levelling or softening agents.  The Specification as open to inspection under Sect. 91 includes also compounds prepared from sulphonamides which may contain a primary or secondary amino group.  As examples of such compounds, there are mentioned paraacetylamino-benzene sulphonamide and 2-(paraacetylamino - benzenesulphonamido) - thiazole.  This subject-matter does not appear in the Specification as accepted.
