Title: Improvements in the purification of tungsten ores and residues containing oxide of tungsten
IPC: C22B34/36
Filed: 1920-10-28
Abstract: Tungsten ores such as wolframite or scheelite are submitted to the action of a halogen or gaseous halogen acid, e.g. chlorine or hydrochloric acid, or a mixture thereof, with or without the addition of hydrogen, at such a temperature as to convert some of the constituents of the ore into volatile halogen derivatives.

Title: Combing machine for wool and like textile fibres
IPC: D01G19/02
Filed: 1950-12-18
Abstract: 685,589. Combing machines. MILLER, L. P. Dec. 18, 1950 [Dec. 30, 1949]. No. 30787/50. Class 120 (i). In a circular combing machine for wool and like textile fibres, a large outer combing circle is maintained stationary and an inner combing circle tangent to the outer circle is rotated in a planetary motion along the inner circumference thereof. This permits the feeding of slivers from cans or from larger balls than usual. As shown, a machine comprises a stationary outer circle 15 and three inner circles 17, which are rotated on their own axes and are supported on a rotary plate 20. Electric or steam heaters are located below the inner and outer circles. Sliver is fed to the machine through feed boxes 12 from balls 10 in stationary racks 11 or from individual stationary cans. As plate 20 rotates, circles 17 are rotated on their own axes through planetary gearing so as to effect a rolling motion around the inside of circle 15. A dabbing brush 21 located above the point of tangency of each circle 17 with circle 15, and rotating with circle 15, is reciprocated rapidly up and down by an electric motor. Drawing-off rolls 22, 24, and aprons 25 for the outer circle, drawing- off rolls 30, 31, and aprons 32 for each inner circle, and star wheels 29 for orienting the fibres on the inner circles towards the rolls 30, 31, are carried by plate 20 ; each star wheel may be driven by the motor driving the adjacent dabbing brush. Combed slivers from the outer and inner circles are doubled at each pair of rolls 30, 31, into a common end, the three common ends so formed being combined in passing upwards through a rapidly rotating falsetwist trumpet 35; the combined sliver then passes through a second false-twist trumpet revolving in the opposite direction, and finally through a third false-twist trumpet, which removes the false twist, to a coiler can or ball winder. A noil brush 36 and a noil shoot 37 are provided for each circle 17. Feed boxes 12 are rocked by cams 39 rotating with plate 20, so as to feed an increment of uncombed sliver to the outer circle between each pair of drawing-off rolls 22, 24, and the point of tangency of the following inner circle 17; the balls 10 are rotated slightly, to give the necessary slack, by a ratchet feed operated by another cam rotating with plate 20. Aprons 25, 32, together with drawing-off rolls 22, 24, 30, 31, are slowly reciprocated vertically to equalise wear, the drawing-off and idler rolls being carried on a plate which rotates with plate 20, but is reciprocated vertically by an electric motor supported by plate 20. The drawing-off rolls, the first and second false-twist trumpets, and a coiler can for the combed sliver are, in addition to the inner circles 17, driven by gearing from the drive to plate 20, which may be an electric motor fixed to the plate, or an outside drive.
