Abstract: 1,239,538. Gyratory crushers. ALLISCHALMERS MFG. CO. 19 May, 1970 [26 May, 1969], No. 24177/70. Heading B2A. The concave ring 11 of a gyratory crusher is provided with a ridged-and-grooved profile which equalizes rotor between the wider gap upper end and the smaller gap, fine-grinding lower end permitting more accurate crushing gap setting by a known piston/cylinder arrangement 19. The concave ring has a conical concave inner surface having an apex end of smaller diameter than a base end and forming an outer wall of the crushing chamber 17, the inner surface of the concave ring having an annular stepped configuration along its axial length, comprising a series of alternately arranged annular crushing surface 20 and annular connecting surface 21. Each annular crushing surface 20 is angularly disposed relative to an adjacent connecting surface 21 and relative to a central axis A-B of the concave ring. The conical concave inner surface of the concave ring also has a corrugated configuration, the corrugations comprising ridges 25 and grooves 26 extending from apex to base in a plane parallel to the central axis of the concave ring. The corrugations terminate at one of the annular crushing surfaces 20' which is spaced, in the axial length of the inner surface of the ring from the annular crushing surface 20" adjacent the base end. The ridges of the corrugations are curved surfaces.

Abstract: 1,251,661. Gold separation of gas mixtures. BRITISH OXYGEN CO. Ltd. 24 April, 1969. [25 April, 1968], No. 19766/68. Heading F4P. Separation of ammonia synthesis purge gas into a gaseous hydrogen-nitrogen gas mixture, liquid argon and liquid methane is effected by cooling compressed feed gas mixture in heat exchangers 2, 3, 4 separating in a column 5 into the gaseous hydrogen -nitrogen mixture and into a mixture of liquid nitrogen, argon and methane, expanding the latter at a valve 10 into the high pressure stage 12 of a double column 12, 13, withdrawing separated liquid methane through a valve 18, and expanding separated liquid argon-nitrogen mixture at a valve 14 into column 13, withdrawing product liquid argon from the base of low pressure column 13 and withdrawing overhead gaseous nitrogen and using at least a portion thereof in a nitrogen refrigeration cycle to provide the cold requirements of the process. The withdrawn low pressure nitrogen is warmed in heat exchangers 15A, 22 a portion thereof is warmed to ambient temperature at 23, 24 compressed at 20, a portion thereof is expanded at 21 and added to the low pressure nitrogen withdrawn from column 13 and assists in cooling exchangers 15A, 22. The remainder of the compressed nitrogen after being cooled at 23, 22 heats the reboiler 9A, 9 of columns 12, 5 after which the so liquified nitrogen is in part fed through a line 7 as reflux to column 5 and the remainder is valve-expanded and passed through condenser 8 of column 5 and added to the low pressure nitrogen overhead from column 13.

Abstract: 1,259,289. Change speed gear control. SUNDSTRAND CORP. 23 Dec., 1968 [27 Dec., 1967], No. 61210/68. Heading F2D. The gearing disclosed is the same as in Specification 1,221,857 but the control is different, having a similar governor controlled valve 65, a modified forward/reverse valve 130, the shift, zero pressure control, and neutral governor valves of Specification 1,221,857 being replaced by different valves 132, 134, 136, 137, 138. A variable speed gear between an input and an output shaft (14, 21), Fig. 1 (not shown), includes two hydrostatic units 23, 35 connected by conduits 112, 113 and a two ratio gear, each ratio being engaged by a separate clutch 53, 55, and when changing ratio one clutch is engaged before the other is disengaged. This is preferably done by the sequence valve 136, which receives fluid pressure for the clutches via lines 156 ... 158 except when the valve 130 is in its central (neutral) position. When this valve 136 receives a pressure signal series via a line 175 from the shift valve 132 the clutch 55 is then actuated via lines 170, 165 before the sequence valve moves to connect the clutch 53 to drain via lines 163, 171, 174, 358. Movement of the valve 136 changes over the connections 178, 179 for varying the displacement of the swash plate 115 to their supply lines 176, 177 via the governor controlled valve 65 and the valve 130. To reduce the pressure difference between the conduits 112, 113 either when the engine is idling, or to a value selected by manually positioning a slide 281 in the valve 137, the swash plate 115 is adjusted by piston 116 in response to the pressure difference between lines 112, 113, valve 137 connecting lines 292, 293 when the difference is sufficient, and the spool 312 of valve 138, positioned by the pressures in conduits 112, 113 via lines 301, 302, to give the right direction to movement of the swashplate. For operation of the shift valve 138 see the abridgment of Specification 1,259,290 of identical disclosure.

[Also in Division C1] Float glass 20 advancing in ribbon form along a bath of molten metal 1 over which a protective atmosphere is maintained is surface treated by maintaining adjacent the upper surface of the glass a body 34 of material for coating the glass, regulating the temperature at which vapour is released from said body, and thermally conditioning the glass so that its surface is below the temperature of the released vapour and is receptive to a coating of said material. Molten glass 9 from 12 is poured as a ribbon 20 on to the surface of molten tin or tin alloy 1 whose temperature is regulated by means 22, and chamber 17 is heated by heaters 23 and supplied with a nitrogen, helium or argon atmosphere through ducts 24. Three types of vapour source are described: (1) a beam 30, extending across the width of the glass, of refractory material (e.g. W or Mo) having side walls 32 and porous floor 33, which serves as a container for coating metal 34 which on electrical heating melts and passes through floor 33, giving rise to vapour of the metal immediately adjacent the glass surface; (2) a narrow A.C. heated refractory metal bar from which molten coating metal hangs by surface tension near to, or in non-wetting contact with, the glass surface, giving rise to vapour immediately adjacent thereto, and (3) a crucible holding coating material and having a hood defining vapour channels through which vapour is downwardly deflected on to the glass. The coating may be Au, Ag, Cu, Sn, Bi, Zn, or Al or an oxide of Bi, Si, Ti, Fe, or Sb, and a SnO 2  coating may be formed by depositing Sn and subsequently oxidizing. Coatings of Co, Ni, Mn, or Cr may be applied, oxidized, and the oxide diffused into the glass surface to give coloured glass. Mixed metal coatings may be applied, and two successive vapour sources may be used.
