Title: Improvements in or relating to the emulsion polymerisation and copolymerisation of methyl alpha-chloroacrylate
IPC: C08F20/22
Filed: 1943-01-13
Abstract: Methyl alpha-chloroacrylate is polymerized in emulsion at a temperature between the freezing point of the emulsion and 80 DEG  C. The aqueous medium contains a dissolved salt of perdisulphuric acid and an "acid-stable" dispersing agent comprising a long chain acyclic hydrocarbon substituted with only one radical which is either -SO2OX or -OSO2OX where X is an alkali metal.  "Acid-stable" refers to agents whose activity is unaffected in media of pH 3 to 5, e.g. excludes soaps.  The process is equally applicable to the copolymerization of methyl a -chloroacrylate with one or more other polymerizable compounds which contain a single ethylenic linkage.  As dispersing agents a list of long chain alkyl acid sulphates and sulphonates is given. The polymerization system may also contain inorganic salts, long chain primary alcohols, carbohydrate derivatives and polyvinyl alcohol.  Polymerizable materials include esters of acrylic and methacrylic acids, (list); acrylo- and methacrylamides or mono-alkyl substitution products thereof; unsaturated ketones, e.g. methyl vinyl, phenyl vinyl and methyl isopropenyl ketones; and vinyl carboxylates, e.g. vinyl acetate, propionate and stearate.  In examples the catalyst is ammonium perdisulphate and the dispersing agent sodium cetyl sulphate or the sodium salt of sulphonated paraffin oil, and the polymerization is described of methyl a -chloroacrylate alone or together with (1) methyl acrylate, (2) butyl methacrylate, (3) vinyl acetate, (4) diethyl itaconate, (5) furylethylene, and (6) unsymmetrical dichlorethylene.

Title: Improvements in control systems
Filed: 1941-01-17
Abstract: 544,756. Fluid-pressure servomotor-control systems. FOTHERGILL, H. Jan. 17, 1941, No. 695. [Class 135] A gimbal-mounted platform stabilized by a gyroscope acting through fluid pressure servomotors has the power devices supplied with compressed air through restricted passages and exhausted through leak-off devices and coupled to the gyroscope. In the arrangement shown in Figs. 1 and 2 a bomb sight 20 is supported on a table pivoted on an axis 22 in a gimbal 23 pivoted at 24 in a stand 25. The table is tilted relatively to the ring by a double-acting power cylinder 15a supported by the ring 23 and the ring is tilted by a power cylinder 15 supported by the frame. A gyroscope rotor 26 mounted in gimbal rings 27, 28 is carried by a bracket 29 secured to the table which bracket also carries leak-off valves 4, 4a, connected by links to the outer and inner gimbal rings respectively. The two ends of both cylinders are supplied through chokes 50 with compressed air from a single source 9. In the form shown the leak-off valves comprise a tubular member adapted to cooperate with two series of ports 5 leading to annular chambers connected by pipes 10, 10a to the opposite ends of the cylinder. By using a series of ports a film of gas exists between the valve and its seating so reducing friction. A blade movable between opposed leak-off orifices may replace the tubular sleeve. Where the object to be moved is unbalanced chokes of different size may be used or different operating pressures may be used. The bomb sight is stabilized in azimuth by a gyroscope 26a the outer gimbal 28a of which is linked to a leakoff valve 4b controlling a power cylinder 39 supplied with compressed air through chokes. The leak-off valve casing is carried by a gear wheel turning on the same axis as the gimbal ring 28a and connected through an idler pinion 42 with a gear wheel carried by the bombsight. Specifications 546,081 and 546,087 are referred to.

Title: Improvements in or relating to packing machinery
IPC: B65B19/20
Filed: 1931-01-09
Abstract: 367,111. Packeting cigarettes. MOLINS, W. E., CHALMERS, J. W., JACKSON, D., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Jan. 9, 1931, No. 790. [Class 94 (i).] A machine which automatically packs at least two batches of cigarettes arranged side by side with adjacent batches each separated by a partition, into a box, comprises means for feeding adjacent batches of cigarettes to opposite sides of a partition automatically fed into the path of the cigarettes, and means operable to insert the separated batches of cigarettes, together with the partition, into a box. Foil feeding apparatus 13 cuts a rectangular blank of foil from a web and applies the blank, by rotary suckers, to a pocket 11, attached to and moved by an intermittently moving chain conveyer. The pockets are formed with central slots to accommodate a longitudinally blunt-topped knife 19, about which a descending tucker creases the foil. The edges of the foil are guided by guides 22, and the conveyer moves the creased foil beneath mechanism which sharply defines the creases. This consists of cam operated arms 23, 24 pivoted at 25, 26 with end plates 31 the foil being put under considerable tension by two depending spring plates carried by the arms 23, 24. The foil 18 is now as shown in Fig. 9, a central upstanding ridge 18a having been formed. The cigarettes are fed on to it, from opposite sides, from hoppers 33 fitted with vanes 34, by pushers 36 moved by chains 35. After the bottom layers have been fed-in at position A, a mechanism, fitted in duplicate, may be employed to deliver two strips of paper &c. on to the upper surface of each layer to act as separating strips. These strips may be cut from webs and moved into position by two contacting belts. The upper layers of cigarettes are fed in at position B, and on further movement of the pocket 11, the edges 18b of the foil are folded over by folders 39, 40 to present a partially wrapped assembly, Fig. 12. Cam-operated presser plates, not shown, may be employed at the cigarette filling station to ensure that the cigarettes are pressed truly into the foil-lined pocket. A plunger 47 ejects the partially-wrapped assembly into a pocket 48 of a rotary turntable 49 from which it is ejected by a plunger 62, operatively connected to the plunger 47, on to a plate 60, which carries a blank of foil 64, Fig. 13, cut from a web and applied to the plate by a suction roller. Closed boxes 51, contained in a magazine 52, are fed along by an intermittently moving chain to a suction device 55, 56 which turns back the lid of the box, ready to receive the charge, which is pressed through an aperture 61, in the plate 60, by a cam-operated presser 65. As the box is again moved forward the edge of the plate 60 folds back the edge 64a, Fig. 14, on to the assembly, the other edge 64b being folded back into the lid. The box is now moved by a conveyer 72 past a folder 73 which closes the lid, the completed box being discharged on to a table. Specification 359,088 is referred to.
