Title: A method and device for winding yarn
IPC: B65H51/20
Filed: 1964-08-14
Abstract: 1,031,608. Winding yarns. ELITEX SDRUZENI PODNIKU TEXTILNIHO STROJIRENSTRI. Aug. 14,1964 [Aug. 14,1963], No. 33162/64. Heading D1J. A reserve of yarn is accumulated between a knotter 8 and the bobbin 14 being wound so that on thread breakage the bobbin may continue being wound while the yarn ends are being knotted, the yarn then being fed to the reservoir at a speed greater than the winding speed to replenish the reservoir. In one example a pneumatic nozzle 9 draws yarn 1 off cop 2 through brake 4, electronic clearer 5 or mechanical clearer 6 and sensor 7, cutting mechanism 18, and gripper 19 for holding the broken yarn end, the air flow speed in the nozzle and thus the yarn speed being dependent on the extent the yarn fills the perforated vessel or wire cage 11 and thus blocks the apertures thereof. In the case of heavier yarns, the yarn may be passed around a pair of rollers rotating at a faster speed than driving drum 15 before reaching the nozzle 9, the yarn slipping on the rollers when the reservoir is full or the yarn breaks. Alternatively the yarn may be fed by two rollers into a chamber against the gravity-and/or spring-pressure of the top thereof, the rollers being stopped either on thread breakage, or on the top being pushed sufficiently far back. One knotter may serve more than one winding unit and when more than one yarn breakage occurs at the same time the winding speed is diminished to avoid emptying of the yarn reservoirs.

The container 10 is clamped to a sealing plate at the top of the base by an apertured member 24 and a nut 27 screwing on a vertical tube 14 and the open end of the container and member 24 are enclosed by a cap 29 which has a rod 30 extending through the tube 14 to a base plate 31 where it is provided with a wing nut. To prevent unautho rized removable of the container, the cap 23 has projections 35 engaging the top of the tube 14 and the wing nut is locked by the bolt of a key-operated lock. The measuring means comprises a thick disc 17 rotatable round the tube 14 and normally held by a spring 19 in a position in which a measuring aperture 18 is in registry with an aperture in the sealing plate. On insertion of a coin. the disc 17 can be rotated by a handle 20 to bring the opening 18 in registry with a discharge aperture 15 leading to a shoot 16. In an alternative construction, the disc 17 may discharge in both its limiting positions, two apertures being provided in the sealing plate and also two discharge apertures 15. The capacity of the aperture 18 may be varied by fitting one or more inserts. Coin action. In the absence of a coin, rotation of the disc 17 is prevented, after a limited movement, by the engagement of a stop 43 with the nose 42 of a spring- loaded lever 39. When a correct sized coin is inserted, it engages a cam-shaped recess 41 in the lever 39 and withdraws the nose 42 from the path of the stop 43. and is then carried along a track 44 until released through an aperture 45 into the base of the machine. A slidably adjustable coin gauge 37 either prevents the entry of too large coins or allows too small coins to fall through an aperture 38. A fixed ratchet 46 co-operates with a double-acting fullstroke pawl 47.

IPC: C01B3/46
Filed: 1928-11-16
Abstract: 323,864. Tyrer, D., and Imperial Chemical Industries, Ltd. Nov. 16, 1928. Cracking. - In the thermal decomposition of hydrocarbon vapours or gases to yield hydrogen, carbon monoxide, and carbon which is deposited such a limited amount of steam is added to the hydrocarbons that the process is thermally self supporting, the steam reacting with the carbon to form water gas. Coke oven gas containing 30 per cent of methane is mixed with from 5 to 16 per cent of steam and enters by an inlet 4 a regenerator 1, before passing through a bed of coke 3 in which the methane is decomposed. The resultant gases pass through and heat a regenerator 2 on the way to an outlet 5. Air is then preheated in the regenerator 2 and re-heats the coke bed 3 and regenerator 1, and during this blow some air may be bye-passed through a valve 6 to burn any carbon monoxide formed. To minimize the extent of carbon monoxide formed, a high blast rate should be used. The coke may be impregnated with catalysts to accelerate the reaction.
