Patent GB-963525-A (GB)
Title: Synthetic fibres
IPC: D01F6/16
Filed: 1962-08-07
Abstract: Synthetic fibres are made which consist of a water-insoluble polymer or copolymer containing 40 to 100% by weight of cyclic imide groups of the formula: <FORM:0963525/C3/1> in which R represents hydrogen or a lower alkyl group. The polymers may be made by heating at 110-250 DEG C. in the presence of water a copolymer of acrylamide (or an N-alkyl derivative thereof) and an alkyl methacrylate, or copolymer of methacrylamide (or an N-alkyl derivative) and an alkyl methacrylate. Other monomers may be present in the copolymers, e.g. methacrylonitrile, esters of itaconic, fumaric and maleic acids, vinylidene chloride and styrene. Alternatively, when it is desired to effect the production of cylic imide groups in a preformed fibre, a copolymer of methacrylonitrile and acrylic acid in fibre is isomerized by heating at 150-250 DEG C. The polymers are soluble in formamide, dimethyl formamide, dimethyl sulphoxide and formic acid, and may be plasticized with glycol or polyethylene glycol. The polymers may be spun into fibres by wet spinning or melt spinning techniques.

Patent GB-391234-A (GB)
Title: An animal trapping machine
IPC: A01M23/04
Filed: 1931-11-03
Abstract: 391,234. Animal traps. LILLY, E. T., Broughton Cottage, Alma Grove, and SEYMOUR, A. W., 45, Bemerton Street, both in Islington, London. Nov. 3, 1931, No. 30376. [Class 5 (i).] A self-setting animal trap comprises, in the entrance chamber, a sliding and tilting platform which is freed by the entry of an animal into the trap so that, if a second animal should attempt to enter the trap, before the first animal has passed into the receiving chamber, the said platform may tilt and so prevent such entry. An animal entering the trap at 56 depresses the shutter 7, causing the axle 20 to move towards the front of the trap in which position it is looked by means of the locking arm 43, so freeing the platform 18 from engagement with the member 19 so that if a second animal should attempt to enter the trap the platform 18 may pivot about the axle 20 so preventing such entry. The animal passes from the entrance chamber 51 through an aperture in the member 4 on to the platform 3 and proceeds along such platform until its weight counterbalances the action of the springs 40, 40A and clip 6, whereupon the platform tilts about the axle 5. Tilting of the platform 3 rotates the levers 37, 41 causing the sliding carriage 25, and so the pivoted screen 15 to move rearwardly. Further, rotation of the cam lever 37 causes the cam lever 38 and so the axle 14 and crank 13, to rotate bringing the crank 13 into engagement with the tail-piece 12 and raising the shutter 7. Engagement of the members 12, 13 closes the primary circuit of an induction coil mounted in the slidable box 52, the secondary of such coil being connected to the platform 3 and either to the tail-piece 12 or crank 13, a shock being thus imparted to the animal standing on the platform 3 by engagement of the rising shutter 7 with the animal's tail. The shock impels the animal forwardly, whereupon it jumps off the platform 3 to the spring-controlled platform 28 and passes through the non-return door 31 into the removable receiving container 33. Under the action of the springs, the platform 3 returns to its normal position, the electric circuit is broken and the axle 20 is released from locking arm 43 by engagement of the stud 53 on the arm 46 secured to the lever 41 and the projection 54 on the member 44 pivoted on the locking arm 43, the trap thus becoming re-set. If, however, the first animal, after passing over the shutter 7 and operating the locking arm 43, decides to withdraw, its weight on the platform 18 will cause such platform to tilt, so releasing, by means of the arm 45, the locking arm 43. The trap is wholly enclosed, except at 56, and may be surrounded with a mesh construction to facilitate access of the animals to the aperture 56. A bait box is slidably mounted in the outer casing of the trap behind the partition 15. According to the Provisional Specification, the bait box swings with the screen 15.

Abstract: 352,345. Embossing - presses. MASCHINENFABRIK WINKLER FALLERT & CO., AKT.-GES., 36, Wylerring- strasse, Berne, Switzerland, Oct. 13, 1930, No. 30591. Convention date, Oct. 13, 1929. [Class 100 (ii).] In a press for moulding stereotype matrices and the like, having its pressing surface moved by toggle levers, non-circular toothed discs are provided in the gearing between the source of power and the crank by which the toggles are moved, and move the pressing surface with greatest gear at the moment of maximum pressure. An electric motor a drives, through a clutch b, worm c, wormwheel d, and spur-wheels e, f, g, a large spur-wheel h which is keyed on a shaft i. On the shaft i is mounted a toothed elliptical wheel k which drives' a second elliptical wheel m on a shaft l by which toggle levers n, o are moved by means of a crank p and connecting-rod q. The lower toggle lever o is seated in side-plates r which carry the press-head s and move it up and down. The elliptical gears k, m describe the same number of revolutions as the spur-wheel h but alter their relative gear proportion during each revolution in such a way that the press-head s is moved quickly during its idle stroke, but moves gradually slower towards the end of its downward stroke. At the moment of maximum pressure the shortest radius of the elliptical wheel k is opposite the longest radius of the elliptical wheel m, so that the press-head will exercise a correspondingly increased pressure.

Abstract: 1392391 Boring earth etc; wells &c PHILLIPS PETROLEUM CO 30 June 1972 [1 July 1971 9 Feb 1972 (2)] 30822/72 Heading E1F '[Also in Division C3] Aqueous gels for use as drilling fluids, fracturing fluids or plugging fluids or for use in fluid drive processes for secondary recovery of mineral oil consist of (a) a water soluble cellulose ether, preferably carboxymethyl cellulose, (b) a water soluble compound, preferably Na 2 Cr 2 O 7 , of a polyvalent metal capable of being reduced to a lower polyvalent state and (c) a water soluble agent, preferably Ma 2 S 2 O 4 , able to reduce at least a portion of the metal of (b) to its lower state. Depending on the intended use the components may be added in various orders, but (b) and (c) are never together in solution without (a). When used as a fracturing fluid (see examples 12-18) in the fracturing of a porous formation penetrated by a well, a basic fluid of (a) plus (b) or (c) in solution is made and pumped down the well under a pressure sufficient to fracture the formation and, during the pumping adding whichever of (b) or (c) was absent from the base fluid. If the formation is susceptible to acid then a slug of acid may be pumped down after the gel. The viscosity of the gel rises after addition of the final component but after a while declines. This facilitates removal of the gel after fracturing. The gels may also be used to plug fractures (see examples 19 and 20) and so prevent loss of drive fluid in fluid drive processes. These gels are formed as above, one of (b) and (c) being withheld until the pumping stage. Examples 8-10 illustrate the suitability of the gels as drive fluids. Example 11 illustrates its use as a drilling fluid.
