Title: Circular loom
IPC: D03D37/00
Filed: 1971-04-19
Abstract: 1349184 Circular looms GEORG FISCHER AG BRUGG 19 April 1971 [10 March 1970] 23003/71 Heading D1E Circular looms. A circular loom has two groups of warp threads, the first of which 15 is issued from individual yarn magazines 14 arranged in a circle and the second of which 13 is fed between the magazines 14, and the weft 23, 24 is inserted by rotating inserters 20, 21 which push the second group of warps to the sides of the magazines and guide the weft 23 down and around the magazines, so that it is laid inbetween the two groups of warps, alternately from one side then from the other of the warp. The weft inserters 20, 21 consist of helical tubes which extend around the magazines and through which the weft passes, and which are spaced around the loom on a rotating ring 17 and a disc 16. The wefts are beaten up by a device, Fig. 13 having dents 29 resiliently attached to a ring 28, which dents are pushed outwardly to pass between the warps by a wheel 34 on a arm 33 rotating just behind the weft inserter. Both sets of warps may be fed vertically downward, Fig. 10, or they may be fed radially inward, (Fig. 15, not shown) to increase the warp density. The magazines may be supported purely by the weft inserters which are spaced so that each magazine has at least three inserter tubes passing around it (Fig. 9, not shown) or magnetic supporting means may be provided (Fig. 5, not shown). The inner weft inserters 20 may be supplied with yarn from bobbins arranged on a central spindle 26 of the loom. Multiple fabric looms. In an alternative embodiment, Fig. 19, magazines 14 are spaced in groups 60, 61 around the circumference of the loom and corresponding groups of magazines 62, 63 or warp beams are arranged above them to supply the second group of warps. Weft yarn is supplied from bobbins 64, 65 above the second group of warp supply means and inserted by first and second inserters 68 and 69 which rotate in opposite directions around the loom on the inside 68 and outside 69 of the loom respectively. Guide rails 72, 73 around the second group of warp supply means guide the weft so that the inserter 68 first carries the weft in one direction to the gap 80 between the fabrics where the weft slips out of it and is picked up by the second inserter 69 which carries it in the opposite direction so that the weft traverses continuously from side to side of the fabric. Tensioning warps. The second group of warps may be supplied from magazines 38, Fig. 17 which are mounted on members 40 slidable radially of the loom and biassed in the outward direction and which are acted upon by a wheel 42 rotating radially in line with a weft inserter. The wheel pushes the members 40 inwardly to slacken the corresponding warps as the inserter begins to engage them. Finishing fabrics. In one embodiment (Fig. 18, not shown) the finished fabric is brushed by combing cylinders (46, 47) as it leaves the weaving area to increase the warp density.

Abstract: 316,271. Oliver United Filters, Inc., (Assignees of Weir, J. W.). July 26, 1928, [Convention date]. Paraffin and mineral waxes, extracting.-Wax is separated from a wax bearing oil by adding a wax adherent medium of a flocculent nature, e.g. fuller's earth, kieselguhr, filter cel &c. to the oil after it has been chilled and then filtering off the solidified wax. The oil contained in a reservoir tank 1 passes downwards through vessels 4 and 8 cooled by brine &c., and is forced by a pump 10 through coils 11 of a refrigerator 12, into a tank 15 where it is mixed with the wax adherent medium supplied from a vessel 13 bv a feed worm 14. The mixture, at a temperature of -20‹ to -40‹ F. passes downwards through a control box 18, to a pressure or suction filter 19 to yield the de-waxed oils, flowing out through pipe 20. The wax may be separated from the filter cake, discharged through shoot 21, by hot water or a suitable solvent. The Specification as open to inspection under Sect. 91 (3) (a) states that the fuller's earth &c. may be added before or during the chilling of the oil. This subject-matter does not appear in the Specification as accepted.
Patent GB-767851-A (GB)
Title: Production of nonionic surface active agents
Filed: 1954-08-09
Abstract: Poly-oxyethylene ethers of higher alcohols are prepared by initially reacting ethylene oxide with a primary or secondary alkanol containing 10 to 17 carbon atoms in the presence of an acidic catalyst at a temperature between 0 DEG  and 80 DEG  C. until 0.2 to 4 mol. of ethylene oxide have reacted per mol. of alkanol, neutralizing the resulting reaction mixture and recovering the mono-alkyl ethers of ethylene and polyethylene glycols therefrom, normally by fractional distillation under reduced pressure to remove all components boiling below the B.P. of the alkyl mono-ether of ethylene glycol, and thereafter reacting the said recovered ethers with additional ethylene oxide at a temperature within the range of from 80 DEG  to 200 DEG  C. in the presence of an alkaline catalyst until a 0.5 weight per cent aqueous solution of the resulting reaction product has a cloud-point within the range of 10 DEG  to 100 DEG  C.  The first stage may be effected at pressures from atmospheric to 50 p.s.i.g., using as acidic catalyst for example, sulphuric acid, phosphoric acid or a Friedel-Crafts catalyst such as a fluoride or chloride of boron, aluminium, iron, tin or titanium or a complex of such a halide with diethyl ether. The second stage is carried out under about atmospheric pressure, the preferred catalyst being an alcoholate which may be an alkali metal alcoholate of the initial alkanol or of the mono-alkyl ether of a mono-or polyethylene glycol made in the first stage. Suitably, these alcoholates are made in situ by reacting an alkali metal or its oxide, hydroxide or alcoholate formed from a lower alkanol, with the stripped product of the first stage.  The final products contain from about 4 to 20 ethenoxy units and have a narrower molecular weight range and better wetting action than are achieved when an alkaline catalyst only is used in their preparation.  The preferred products are prepared from those secondary alcohols wherein the hydroxyl group is attached to or near to the central carbon atom of the carbon chain.  Examples illustrate the two-stage preparation of the specified ethers from 2-butyl octanol, 2 : 6 : 8-trimethyl-4-nonanol, 1-dodecanol, 5-ethyl-2-nonanol, 3 : 3 - di - neopentyl - 1 - propanol, tridecanol-1, 3-ethyl-6-undecanol, 2-methyl-7-ethyl-4-undecanol, 6-dodecanol, 3 : 9-diethyl-6-undecanol and 3 : 9-diethyl-6-tridecanol and, for comparison, the single stage preparation of ethers of some of these alcohols using only either an alkaline or acid catalyst. The products obtained may be worked up by neutralization to pH about 7-9 and sometimes with a subsequent treatment with anhydrous magnesium silicate.  Water in amounts of 5-10 per cent by weight may be added to the product to prevent crystallization. 2-Methyl-7-ethyl-4-nonol and 2 : 7-dimethyl-4-decanol are other specified alcohols.

Pineapples or other soft articles to be sliced, are delivered from a belt conveyer 16 into a sleeve 7, wherein they are engaged by a pair of feed worms 11 extending through diametrically opposed slots 9 in the sleeve 7 and continuously advanced to a rotary knife 4 to be cut transversely a single slice at a time. The precored and cylindrically cut pineapples are fed via a shoot 29 from a moving belt 28 on a trimming table 2 to the belt conveyer 16 which has a cylindrically grooved outer surface 30 aligned with the feed end 15 of the sleeve 7. The belt 16 extends into a longitudinal slot 14 in the lower surface of the sleeve 7 whereby the pineapples are centred in the sleeve 7 and carried to the counter-rotating feed worms 11. The knife 4 passes through a gap 36 formed between the discharge end 10 of the sleeve 7 and the adjacent end 34 of an aligned discharge sleeve 35 having an associated belt 38 which carries away cut slices. The feed devices and knife 4 are synchronized so that the continuously moving pineapple is advanced one slice thickness for each rotation of the knife 4. A plurality of circumferentially spaced knives may be employed and these may also be spaced axially of the sleeve 7 which would be provided with further gaps 36. Normally open micro-switches 23, 27 are arranged in parallel in the drive motor 18 circuit whereby engagement of a pineapple on the belt 16 with the first switch 23 starts the motor 18 after a predetermined time delay and the passing of the last pineapple beyond the second switch 27 causes the motor 18 to stop.
