Title: Improvements in or relating to drafting frames
IPC: D02J1/22
Filed: 1963-05-09
Abstract: 1,004,410. Synthetic filaments; drawing frames. G. TONOLO. May 9, 1963, No. 18448/63. Heading B5B. A drawing frame or apparatus for stretching synthetic filaments comprises a group of feed rolls and one or more groups of draw rolls. As shown in Fig. 1, a group of rolls indicated generally by the reference numeral 1 is mounted on the front face of a casing 2 having a front wall 19 (Fig. 2, which is a cross-section taken along the line II-II of Fig. 1) and a rear wall 4 formed with a central circular aperture 5 closed by a convex circular plate 6 provided with a bearing 7, 15, 16 in which is rotatably mounted a shaft 17 on one end 18 of which a pulley 20 is fixedly mounted. Keyed to the shaft 17 is a large-diameter externally toothed gear-wheel 25 engaging four equally spaced gear-wheels, one of which is shown at 14 keyed to a shaft 12 rotatably mounted in a bearing 10, 11 on the rear wall 4 of the casing and a bearing 27, 28 in the front wall 19 of the casing. A large diameter roll is keyed to the portion 29 of the shaft 12 projecting from the casing wall 19. The front end 24 of the shaft 17 is rotatably mounted in the bearing 22, 23 provided in the casing wall 19. An internally toothed gear ring 31 rigidly secured to the gearwheel 25 engages four equally spaced pinions of which one is shown at 37 keyed to the end 36 of a shaft 35 journalled in bearings 33 and 34 carried by the casing wall 19. A small diameter roll 39 is keyed to the outer end 38 of the shaft 35. As shown in Fig. 1, there are four large rolls 30A to 30D disposed symmetrically and radially around the periphery of the gear-wheel 25 and driven thereby and four small rolls 39A to 39D disposed symmetrically and radially around the internally toothed ring 31 and driven thereby but offset by 45 degrees from the large rolls 30A to 30D. The speed ratios of the gear-wheels is devised so that all the rolls run at the same peripheral speeds, a filament F enters the group of rolls 1 by engaging the roll 30A and then passes over and in contact with the inward facing surface of the roll 39A. Thereafter it passes over and in contact with the outward facing surface of the roll 30B and so on in a sinuous path over the remaining rolls. After leaving the roll 39D the filament F passes round a guide roll 43 driven by two gear-wheels 41, 42 and travels the group of feed rolls 1 to an identical group of rolls which are draw rolls and are driven at a peripheral speed which is higher than that of the group 1, e.g. 2 to 10 times the peripheral speed of group 1. There may be a series of two or more groups of feed rolls driven at peripheral speeds increasing throughout the series, so that the drawing of the filaments is effected in two or more stages. The gear-wheels attached to the outer rolls may be driven by individual back gearing in engagement with the internally toothed gear ring instead of by the single large diameter externally toothed gear-wheel 25.

Title: Improvements relating to the production of dichlorostyrene copolymers
IPC: C08F22/28
Filed: 1947-07-11
Abstract: Copolymers ranging from soft and rubbery to hard materials are produced by copolymerizing one or more nuclear substituted dichlorostyrenes and one or more esters of olefin polycarboxylic acids, each having an esterifying radical containing an ethylenic double bond and an esterifying radical free from ethylenic bonds. Suitable acids are maleic, fumaric, itaconic, mesaconic, citraconic, chlormaleic and aconitic acids and the ethylenic esterifying radical may be vinyl, allyl, methallyl, crotyl and furyl.  Examples of radicals free from ethylenic linkages are substituted or unsubstituted straight or branched aliphatic radicals, aryl, alkaryl, alicyclic or saturated heterocyclic ring radicals.  Specified esters are methyl allyl maleate and fumarate, iso-butyl allyl, sec.-octyl allyl, n-hexyl methallyl, benzyl allyl, tetrahydrofurfural vinyl and allyl, ethyl crotyl maleates, cyclohexyl methallyl, o-chlorobenzyl methallyl fumarates, lauryl allyl citraconate, octadecyl allyl itaconate, undecyl allyl vinyl, heptyl benzyl methallyl, lauryl vinyl monocarboxy aconitates. Minor amounts of other copolymerizable compounds, e.g. methyl methacrylate, may be present in the mixture. Polymerization may be effected in mass using, for example, benzoyl or lauryl peroxide as catalyst, or in aqueous emulsion using, e.g., hydrogen peroxide, urea peroxide or ammonium persulphate as catalyst. Suitable emulsifying agents are ammonium oleate, sodium rosinate and quaternary ammonium compounds.  Alternatively a "pearl" polymerization process may be used in which the monomers are suspended in water by agitation in the absence of an emulsifying agent but in the presence of an oil base peroxidic catalyst and a stabilizer, e.g. calcium phosphate and kaolin.  The resins are particularly useful in the manufacture of dental prosthesis which are moulded from a dough of the resin and monomeric material. Moulded and cast articles, e.g. ash trays, insulators and ornaments, may also be formed.  Pigments, e.g. zinc phosphate, cadmium red and titania, and hard materials, e.g. opal and quartz, may be incorporated.  The examples describe the polymerization of 2,4- and 2,5-dichlorostyrenes and also mixtures of all six of the isomers with iso-amyl allyl fumarate, octyl methallyl maleate, n-butyl allyl citraconate, n-hexyl allyl maleate, butyl allyl maleate, sec.-octyl allyl maleate, benzyl allyl maleate, tetrahydrofurfuryl allyl maleate and methyl methallyl itaconate.

Title: Improvements in or connected with Processes for Making Lighter from Heavier Petroleum Oils.
Filed: 1917-12-15
Abstract: 121,356. Ellis, C., Foster, N. L., and Ellis-Foster Co. Dec. 15, 1917. Hydrocarbons, cracking. - Heavy petroleum oils are treated for the production of gasolene &c. by passing their vapours through a zone of progressively increasing temperature, and then subjecting the cracked products to a progressively decreasing temperature until the secondary reactions due to the unsaturated nature of the products of the cracking operation have attained a stage of equilibrium. The apparatus consists of a stack of pipes 4, 11 heated at its base by products of combustion &c. The oil, together, it may be, with water or a solution of a substance such as ammonium nitrate or a catalytic body, e.g. copper or nickel nitrate, is admitted by a pipe G to the upper end of the pipe 4 and travels downwards through successively hotter zones. The products of the cracking operation then travel upwards through the pipe 11, undergoing a gradual reduction of temperature. The products are led through atmospheric condensers 13, 21 and a cooling-coil 22. The heavier condensates are returned by pipes 14, 18 to the cracking-pipe 4; the gasolene emerges by a pipe 24. The cracked products derived from the pipe 4 may also be subjected to decreasing temperatures by passage through a prolonged path constituted by insulated chambers 32. The pipes 4, 11 may be filled with catalytic materials such as nickel, copper, and cobalt. The heating may be rendered more efficient by packing the tubes 4, 11 with nickel, iron, or steel balls, disks, &c., or by using gilled tubes. The temperatures vary between a minimum of 150‹ C. at the top of the heating- chamber and a maximum of 800‹ C. at the base of the heating-chamber, lower temperatures being employed when treating kerosene than are used in treating heavier fractions.
