Title: Improved machine for cutting artificial staple fibre
IPC: D01G1/04
Filed: 1945-07-04
Abstract: 595,108. Controlling variable-speed gearing. COMPTOIR DES TEXTILES ARTIFICIELS SOC. A.R.L. July 4, 1945, No. 17088. Convention date, June 29, 1944. [Class 80(ii)] [Also in Group IX] Variable-speed gearing associated with the drive of a machine for cutting artificial staple fibre (see Group IX) comprises an expanding pulley, the diameter of which is controlled by movement of a feeler or other device sensitive to the slackness or tension of a bundle of filaments to be cut. As shown, a feeler 20 rests on a bundle of filaments A, and is sensitive to variations of slackness therein. Movement of feeler 20 causes connecting rod 26 to move plate 28 about shaft 29, so that one of two projections 34, 35 on a plate 28 raises a corresponding pawl 36 or 37 attached to a lever 40 continuously oscillated about shaft 29 by the engagement of roller 41 with cam groove 42. The pawls 36, 37 co-operate with ratchet wheels 30, 31 fast on shaft 29 which is thus rotated intermittently in one direction or the other according to the position of feeler 20. Movement of shaft 29 rotates a threaded shaft 19 controlling the diameter of a conical-cage expanding pulley transmitting drive from a motor to the rotary knives 6 and feed rollers 3, 4 of the cutting machine. Movement of the conical cage in each direction beyond a certain limit may be arranged to operate an automatic cut-out to stop the motor. Feeler 20 may be replaced by a photo-electric device, or by a device sensitive to variations in tension of bundle A, for example a dynamometric feeler comprising two fixed rollers and one movable roller, the latter being spring-loaded.

Title: Method and apparatus for the final moulding of inflated articles
IPC: B29C35/00
Filed: 1958-05-30
Abstract: 877,170. Moulding inflated articles such as tennis balls. DUNLOP RUBBER CO. Ltd. May 30, 1958 [June 14, 1957], No. 17269/58. Class 87(2). Inflated articles made from rubber or like elastomeric material, such as tennis balls, are moulded in a two-part cavity mould 12, 13 by placing the pre-formed articles 10 in the cavities 11 of mould part 12, applying fluid pressure to the exterior of the articles to compress them, closing the mould, releasing the exterior fluid pressure and heating the mould to moulding temperature. As shown in Fig. 2, the space 19 between the two mould parts 12, 13 is sealed by a flange 17 attached to part 13 and including an inflatable gasket 18 which engages the periphery of the part 12. The upper mould part 13 has a conduit 23 to admit air under pressure to the space 19 when enclosed, thus compressing the pre-formed balls 10 and preventing them from being trapped between the mould parts to form projecting flange on the finished articles. When the pressure is released, the air escapes from the cavities 14 in mould part 13 by means of passages 24 in the surface 21 communicating with the cavities and with the edge of the mould and the conduit 23. Alternatively, instead of simply releasing the pressure, the conduit 23 may be connected to a vacuum for exhausting the mould. Automatic means may be incorporated to halt the closing of the mould parts when the flange 17 of part 13 engages part 12 whilst the gasket 18 is inflated and compressed air applied to the conduit 23.

Title: Improvements in and relating to electric circuit interrupters with arc quenching by arc generated gas
IPC: H01H33/76
Filed: 1938-06-13
Abstract: 515,943. High - tension switches. BRITISH THOMSON-HOUSTON CO., Ltd. June 13, 1938, No. 17530. Convention date, June 29, 1937. [Class 38 (v)] A circuit-interrupter of the type comprising a switch chamber having a solid wall of a material which emits an extinguishing-gas under the action of the arc, has a wall constructed of urea (or other) artificial resin to which the same artificial resin or an artificial resin, such as that known under the Registered Trade Mark " Glyptal," having a similar gas-emitting capacity is added in an already-solid form as a filling to increase the mechanical strength of the wall without impairing its gas-emitting capacity. Condensed artificial resin may be added to the foundation resin in granular or ground form, and gas-evolving materials such as oxamide and magnesium peroxide may be added with the filling material. The latter may be sulphur-free urea resin and the foundation material may be sulphur-containing urea resin. The artificial-resin filling may be incorporated in the foundation resin in the form of solid but flexible threads obtainable, for example, by pressing a plastic resin mass through a nozzle into a refining bath of hot paraffin and subjecting the threads to a preliminary hardening prior to incorporation. The threads may be added as small pieces or as long spun threads or fabric, the spun threads lying concentrically with the tube-axis. For mechanical strength, the threadcontent is increased as much as possible, as by adding the minimum possible amount of foundation resin thereto. It is pointed out that the thread-material must be of such character that it does not liquefy when the surrounding resin is being hardened, but this difficulty does not arise when Glyptal resin is added to urea resin. The Specification as open to inspection under Sect. 91 refers to tubes and pins and to added filling materials other than those of a resinous character. This matter does not appear in the Specification as accepted.

Title: Improved process and apparatus for the manufacture of sulphur dioxide
IPC: C01B17/50
Filed: 1962-05-08
Abstract: <PICT:0994902/C1/1> Pure sulphur dioxide is produced by introducing molten elemental sulphur into a reactor containing oleum maintained at a temperature such that the sulphur does not solidify while subjecting the reaction medium to agitation. The sulphur may be introduced at between 125 DEG  and 155 DEG  C. and the oleum maintained at <PICT:0994902/C1/2> about 120 DEG  C.  Preferably the reaction is carried out continuously, part of the oleum forming the reaction medium being withdrawn from the reactor, and passed into a decanter fitted with an overflow to discharge the oleum whilst the sulphur is returned to the reactor.  Solid sulphur may be deposited on a cooled surface, e.g. in a cooler upstream from the overflow of the decanter, and the sulphur removed by a hot fluid at intervals. The decanter may be maintained at a temperature below that of the reactor but high enough to prevent the sulphur solidifying.  In Figs. 1 and 2, a reactor 1 is fitted with a heating jacket 2 and a stirring device comprising a central cone 3 and impeller screw 4. Oleum and liquid sulphur enter via pipes 5 and 6 and SO2 escapes via pipe 7.  A tube 12 closed at the reactor and extends into decanter 11, fitted with heating jacket 17. A ring of apertures 15 in tube 12 provide communication between the reactor and decanter, the latter being connected with the interior of side tube 8, the opening of which from reactor 1 is only partially closed by plate 13.  The sulphur is solidified on the turns of coil 18. Overflow 21 maintains the liquid level at the desired height in the decanter.  In a modification the reactor and decanter are contained in a single double-walled vessel and separated by a cylinder which is coaxial with the vessel.
