In a stator winding machine, each formerwound coil is held in a gap in one of a number of similar mandrels rotating about a common axis, and the stator is then moved to a suitable position for insertion of the coil. Unwound stators are taken from a conveyer belt by a transfer device (Fig. 8, not shown) and clamped in a support 11, Fig. 2, the fully wound stator being returned to the conveyer belt. The winding machine consists of a six-mandrel circular indexing table 3 and a winding device 8 powered by motor 10. Each of the six mandrels consists of a fixed outer casing 80, Fig. 4, secured to the rotatable indexing table 3 (Fig. 3, not shown). Casing 80 contains a slidable shoe 83 connected to a slide 85 through a slot in the casing. The slide 85 is actuated by a roller bearing 86 in a cam groove of cam 35. The coil former 6 is carried on a splined shaft 88 passing through slide 85 and actuated by another roller follower 89 in another cam groove of cam 35. The former 6 (shown in the winding position) consists of a block 90, a movable wedge 91 attached to shaft 88, and a pad 92. A device for winding single layer or multi-layer coils on former 6, Fig. 6, has the winding wire fed down through hollow spindle 103 to the flyer 8 and then on to the former. The vertical movement of the flyer 8 is controlled from cam 27 via lever 26, the rotational movement being supplied by motor 10, Fig. 2, driving pulley 124, which can rotate freely on the shaft and can be engaged by clutch 24. This clutch is controlled from cylinder 25 by lever 125, to engage the drive pulley 124 or apply a brake 126. When the coil is wound, the machine moves out of the winding station and the winding is moved downwards so that the right-hand part of the coil is moved into gap 95, Fig. 4. The former and the slide 82 continue to move downwards and the wedge 91 is withdrawn from the former and the coil is left freely suspended with an end in gap 95. With the mandrel in the coil-insertion station the stator is lowered to insert the coil. The coil formers may be of different size so that coils of different pitch may be wound, and the actuating cylinders may be operated by compressed gas or hydraulic means, or electrical devices may be used.

Title: Improvements in or relating to the recovery of glycerol from fermented liquors
IPC: C11D19/00
Filed: 1940-09-18
Abstract: 578.260. Glycerine. WALMESLEY, R. A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 18, 1940, Nos. 14328 and 18242. [Class 91] Glycerine is extracted from the concentrated still residues of carbohydrate fermentation by rendering them neutral or alkaline and adding a mixture of a water immiscible nitrogen base such as aniline and a non-acid volatile watersoluble solvent for glycerine such as alcohols with less than five carbon atoms in the molecule, or esters, ethers, ketones, or bases capable of being evaporated from the water immiscible base. The mixture may contain from 30 to 70 per cent. of the alcohol &c. with 70 to 30 per cent. of the nitrogen base. The extract is separated from the residue, evaporated to remove the solvent and the water, and the remaining solution of glycerine in the nitrogen base is extracted with water to remove the glycerine, which is obtained as 85 per cent. glycerine after concentration. This product is finally steam distilled at reduced pressure, oxidised, and again steam distilled to give dynamite glycerine. Glycerine solvents mentioned are methyl, ethyl, and isopropyl alcohols, ethoxy ethyl alcohol, acetone, pyridine, triethylamine and methoxyethyl acetate. In an example, the neutralized residue is extracted three times with thrice its weight of a mixture of 34 per cent. aniline and 66 per cent. isopropyl alcohol. The extractions are carried out below 40‹C. and the extracts are then run into a low pressure steam heated still. The first distillates, boiling at about 85‹C., consist of isopropyl alcohol and water while the final distillate, boiling at about 98‹C., consists of aniline and steam. The aniline solution remaining in the still is separated from the deposit, cooled, and washed in counter current with water or glycerol washings of previous batches, producing a 20-25 per cent, glycerine solution which is then concentrated to 75 per cent. strength. On steam distillation at reduced pressure refined glycerine is obtained. To produce dynamite quality glycerine, this product is diluted to 50 per cent. strength and oxidised with sodium peroxide solution, reconcentrated, and redistilled. The distillate is again diluted to 50 per cent. strength, filtered hot through activated charcoal, and finally concentrated. Specification 515,831 is referred to.
