The head assembly 66 is intermittently driven clockwise through mutilated gears 19, 20 (see Division F2) so that each label passes quartz infra-red radiators 91, 92 to activate adhesive on the labels. Each label is then applied to a package 27 on a conveyer 93, the head being released to its extended position at the application station by a projection 14 engaging the latch 23. Depression and release of the head operate a sleeve valve controlling the application of suction to the head surface, Fig. 4 (not shown). Each operating cycle is initiated by detection of a package 27 either of two parallel arms 67 (one shown) operating microswitches or by photo-electric means. Each label is rolled on by a foam rubber roller 52, or by a roller comprising a number of discs loosely mounted on a spindle, the outer discs being brass and the inner one plastics. The label stack is pressed against retaining lips 31 on the magazine by a pusher 33, which operates a microswitch to warn an operator when there is room in the magazine to accept another bundle of labels. The operator then moves the pusher to the end of the magazine, which operates another microswitch which results in release of a bundle of labels held in reserve above the magazine (Figs. 5 and 6, not shown), to drop into the magazine, exposed whereupon the pusher 33 can be released. To prevent the adhesive face of the end label of this bundle from sticking to its container and to provide a clean drop, a jet of air from the suction plant is directed against the face.

Title: Process for separating acrylonitrile and hydrocyanic acid from mixtures by distillation
IPC: C01C3/04
Filed: 1963-12-17
Abstract: 1,038,070. Purifying acrylonitrile by distillation. KNAPSACK A.G. Dec. 17,1963 [Jan. 16,1963], No.49758/63. Heading B1B. Crude acrylonitrile which contains hydrocyanic acid, acrolein, acrolein-cyanohydrin and water, is purified by stabilizing it with phenothiazine and phosphoric acid and submitting it to fractionation at atmospheric pressure in column 2 to remove HCN, cooling the liquid withdrawn from the sump of the column so that the liquid separates into an aqueous phase and an acrylonitrile phase, fractionating the latter under reduced pressure in column 6 to distil over acrylonitrile and water, cooling the distillate so that it separates into two liquid phases, returning the acrylonitrile phase to the top of column 6, removing a vapour-liquid mixture from the lowest tray of column 6 and fractionating it, under reduced pressure, in column 7 whereby purified acrylonitrile is obtained as distillate. The temperature in the sump of column 6 is preferably maintained at about 75C., and that in the sump of column 7 at about 65C. The acrylonitrile may be prepared by passing propylene, ammonia and air over a catalyst. The resultant reaction gas is neutralized with dilute sulphuric acid, and washed with water. The aqueous solution so obtained is distilled in a stripping column whereby crude acrylonitrile is obtained as distillate. The crude acrylonitrile is stabilized with phenothiazine (1 part per 1000 parts of crude) and introduced through line 1 into column 2. Phosphoric acid (1.4 parts per 1000 parts of crude) is added to the distillate in cooler 3, and part of the distillate is refluxed to the top of column 2. An additional minor amount of phosphoric acid is added to the lower section of column 6. The liquid withdrawn from the sump of column 7 is introduced through line 8 into column 6. The liquid withdrawn from the sump of column 6 contains a high proportion, e.g. 45%, of acrolein-cyanohydrin; this liquid is conveyed through line 13 to filmevaporator 9 where it is separated, at a pressure of 200 mm Hg, into acrylonitrile vapours and liquid acrolein-cyanohydrin. The former are passed to column 6, and the latter is introduced into the reactor fed with propylene, ammonia and air. The aqueous phases withdrawn from separators 5 and 10 are introduced into the top of the stripping column.
