Title: Method of producing an ozonide of an unsaturated fatty acid
Inventor: THORP CLARK E
IPC: C07C51/34
Filed: 1958-07-17
Abstract: An ozonide of an unsaturated fatty acid is made by reacting such an acid in the vapour phase with ozone at subatmospheric pressure and at a temperature not exceeding 360 DEG C.  The reaction may be effected by heating the unsaturated fatty acid to the temperature necessary to cause it to vaporize subsequently and then introducing the heated acid and ozone into a zone maintained at subatmospheric pressure. When the acid is oleic acid, the subatmospheric pressure at which the reaction takes place is preferably between 1 mm and 760 mm of mercury, the temperature correspondingly being between 176.5 DEG C. and 360 DEG C.  The oleic acid may be heated by feeding it through a coil disposed around the ozonizer so that the acid cools the ozonizer and the latter heats the acid.  The ratio of oleic acid to zone introduced into the reactor should be at least 5.88 to 1.  The ozonide is collected in a condenser and may be hydrolyzed with hot water to form azelaic and pelargonic acids.  The water-soluble azelaic acid is removed in solution from which it is crystallized and the unreacted oleic acid and pelargonic acid are separated by fractional distillation under reduced pressure.  The oleic acid is recycled to the ozonizing step.  The oxygen remaining after condensation of the ozonides is cooled and recycled to the ozonizer.

Abstract: 924,719. Folding fabrics. THOMAS BROADBENT & SONS Ltd. June 8,1961 [July 4, 1960], No. 23238/60. Class 42 (2). [Also in Group XVII] In the process of folding laundry, e.g. an apron, the apron is turned over completely after a fold but before a cross fold. The leading edge of an apron a is folded on top of the neckband b and tapes c and then the apron is completely turned over; so that after the next fold, Fig. 8, the neckband and tapes are inside. The apron is then cross folded. The turnover mechanism which is also described in Specification 838,554, operates by the apron e moving, fold first, along a conveyer belt d and coming in contact with a feeler f which operates a valve mechanism h so that compressed air passes through the pipe j into the upper end of the cylinder k having a fixed piston m, thus raising it. The apron e moves into contact with the feeler g which causes raising of the piston p and thus of the arm 8. The arm elevates the folded edge of the apron and holds it between a gripper t and a pad u. The conveyer d carries the apron forward until the arm f is free of the apron and this, after a predetermined delay, permits the cylinder k to drop and the article is then released. The Provisional Specification states that the turn-over mechanism may be as described in Specifications 793,438. and 793,439
