Title: Improvements in or relating to tubulous walls formed from finned tubes
IPC: B21D53/06
Filed: 1962-10-10
Abstract: 986,858. Making tubulous walls. BABCOCK & WILCOX Ltd. Oct. 10, 1962 [Oct. 11, 1961], No. 38337/62. Heading B3A. [Also in Division F4] A method of forming a tubulous wall from a plurality of finned tubes comprises arranging the tubes side by side with their fins in contact and welding together the pairs of fins by progressively moving fusion welding means longitudinally of the fins whilst heating means are traversed before or after the welding means to soften at least the metal of the fins. A wall comprises four tubes 1 having a pair of diametrically opposed longitudinally extending fins 2 arranged side by side and fusion welded together along the fins using a plurality of weld heads. The assembly is preheated completely or locally along the fins by a traversing heating means or subsequent to welding is stress relieved by heating in a similar manner. As an alternative or in addition to the heating process the fins may be hammered to increase their length to compensate for the shortening caused by the welding between dies when in the hot condition prior to or immediately after welding. After welding the hammering may be carried out after reheating, following the welding, or with the fins cold before or after the welding process. Further heat treatment may be carried out to relieve any hardening or stress resulting from the post weld hammering. The fins may, alternatively, be hammered or pressed to form corrugations 3 along their length before or after welding when in the hot or cold state. Corrugations formed before welding will tend to straighten during welding whilst those which remain or are formed after welding will tend to stiffen the wall member.

Patent GB-1013975-A (GB)
Title: Improved process for preparing benzoic acid
IPC: C07C51/265
Filed: 1962-10-10
Abstract: In the manufacture of purified benzoic acid from raw materials obtained by the oxidation of toluene, the raw material is treated with water in more than a sufficient amount to form an azeotrope mmixture with all the unreacted toluene, and the azeotrope and some of the excess water are then distilled off, preferably at a temperature above the boiling point of the azeotrope, e.g. at 90-95 DEG  C. Preferably, the amount of water added is such that an aqueous solution of benzoic acid of 3-5% concentration is obtained after the toluene-water azeotrope and excess water have been distilled off, and the benzoic acid solution is then freed from resinous impurities by decantation, which may be repeated. Finally, the benzoic acid is crystallized and centrifuged.  The mother liquor from the crystallization is used to scrub the toluene-water azeotrope, and the azeotrope is then passed to a separator from which toluene is returned to the oxidation vessel and the aqueous layer is returned to the still in which the azeotropic distillation is effected.  The process is particularly applicable to the products obtained by oxidizing toluene with air at a raised temperature, e.g. 145 DEG  C., in the presence of an oxidation catalyst, e.g. cobalt enanthate.
