Title: Production of sulphate cellulose
Inventor: OMAN ERIK
IPC: D21C1/06
Filed: 1963-03-01
Abstract: In a modification of the sulphate process for separating cellulose from wood-pulp and the like, sodium hydroxide free from sulphide is obtained from a "melt-soda" comprising sodium carbonate and sulphide. The "melt-soda" is treated with a quantity of water sufficient to dissolve all the sodium sulphide, but leave more than half the sodium carbonate undissolved.  This dissolving process can be carried out continuously by the countercurrent method.  The undissolved sodium carbonate can then be dissolved in and recrystallized from a further quantity of water, and then redissolved and causticized.ALSO:In the treatment of cellulosic fibrous material by the sulphate process, the formation of malodourous substances such as methyl mercaptan, methyl sulphide and methyl disulphide is prevented by a pretreatment of the material with an alkaline liquor before the digestion with the sulphate liquor.  The alkali used may be sodium hydroxide or a black liquor from a previous sulphate digestion. The pretreatment liquor may be wholly or partially separated from the fibrous material before the sulphate liquor is added.  The pretreatment may be carried out in the digestion vessel or in a separate vessel.

In order to overcome oscillation of the brake disc in a caliper-type disc brake due to excessive deflection of the axle shaft during cornering, the brake disc 6 is mounted on a bearing 15 on a non-rotatable member 14, which also has secured thereto a non-rotatable brake housing 5, the disc being provided with means interengaging with a wheel 1 whereby it is rotatable therewith. The vehicle wheel 1 is mounted on a flange 7 formed integral with a central boss 8 splined to drive shaft 2 enclosed in an axle housing 3. The caliper housing 5 is mounted on the axle casing 3 and the brake disc is adapted to be driven by the wheel mounting flange 7 keyed to the shaft 2 by means of teeth 18 on a keep plate 17 bolted to the disc. The teeth 18 interengage with teeth 11 on the boss 8 of flange 7 and when the disc is frictionally engaged by friction pads 5a the speed of the wheel 1 is reduced through the keep plate 17, the teeth 18 and 11 and the flange 7. Should the wheel 1 oscillate due to bending of the shaft 2 the oscillations will not be transmitted to the disc because the teeth 11 are permitted to slide on teeth 18. Any oscillation effecting the axle casing 3 will be transmitted to both the brake housing 5 and the disc so that there is no relative angular movement between the disc and the housing.

[Class 80 (ii)] In a variable speed gear for aircraft compressors, the drive is transmitted through one or the other of two hydraulicallyoperated friction disc clutches contained within a common body 18, and having their pistons rigidly connected together to prevent simultaneous engagement. Drive from the engine is transmitted by splined shaft 9 to the hollow spindle 14 of the clutch body 18. The hubs of gears 27, 28 are mounted on spindle 14 and driven from the body 18 through friction disc clutches 21, 23 and 22, 24 operated by pistons 29, 30. The two pistons are rigidly connected by bolts 31 and distance pieces 32 so that movement of piston 29 to the left to engage clutch 21, 23 caused by fluid pressure in recess 16 results in piston 30 moving in the same direction and freeing clutch 22, 24. Similarly, movement of piston 30 to the right by fluid pressure in recess 17 results in the freeing of clutch 21, 23. Fluid pressure to the pistons 29, 30 is supplied through passages 39, 40 leading from passages 36, 37 respectively in a sleeve 38 in the bore of spindle 14. A distributing cock 43 allows pressure fluid to pass to either passage 36 or 37. Fluid from the recess 16 or 17 of the inoperative clutch escapes by centrifugal action through metering orifices 34, 30 respectively. For direct drive, power is transmitted through clutch 21, 23 to the hub of gear 27 which is connected by splined sleeve 47 and member 49 to the compressor shaft 4.
