A device for automatically supplying weft bobbins 5, Fig. 1, to a feed hopper 32 of a loom comprises a suction mouthpiece 9 supported on a lever 6 which is moved up and down by a twoarmed lever 22 having an abutment 21 and operated from a moving part of the loom. As the lever 6 moves, linkwork 12,13 and 14 thereon connected to the mouthpiece 9 is actuated by a bellcrank 34 co-operating with cams 17, 18 and a pawl 19 to move the mouthpiece backwards and forwards as it is moved up and down so that bobbins are lifted up one-by-one from a storage box 4 and dropped into the feed hopper 32, the vacuum through a flexible pipe 10 being cut off at the right moment by a pump 11 being stopped. From the hopper 32 the bobbins are fed by a transfer hammer 1 to the shuttle or alternatively to a drum-type magazine as shown in Fig. 2. The weft ends of the bobbins are also adapted to be captured automatically is shown in Figs. 2 and 4 by an arm 38 which is swung in an oblique plane for a gripper 37 to engage the end of a bobbin 5 in the feed hopper 32 and to withdraw the weft end to a position indicated in broken lines where it is released to be held by a suction device 44. This thread capturing device is arranged to operate twice for each bobbin so that a second attempt is made in case the weft end is missed on the first attempt.

Filed: 1963-11-27
Abstract: In the manufacture of iron or steel in an electric are furnace, the reaction between carbon and oxygen (from the ore fed into the furnace in solid or liquid form with or without added fluxing material) is controlled by one or more jets of oxygen-containing gas having a pressure of at least 8 p.s.i. introduced tangentially into the furnace, either in the upper part of the slag layer or above and preferably at an angle to the horizontal of not more than 60 degrees so that the combined effect of the jet or jets, the blowing action of the arcs and the dynamic force of the gases from the reaction gives a rotary movement to the slag and furnace atmosphere around the furnace electrodes, which counteracts the tendency to build up gradients of temperature or chemical composition in the slag layer.  Fine grained charge material, e.g. ore and lime or other fluxes, may be introduced in the gas jet or jets. A reducing agent such as coal or coke may be added to the oxidizing slag to generate CO.
