Abstract: 529,552. Turning-gears. BOSCH GES., R. June 3, 1939, No. 16341. Convention date, June 30, 1938. [Class 7 (v)] In a starter for aircraft, motor-vehicle and other engines, in which a coupling element such as a claw 14, located in a part 10 of the starter casing which is secured to the engine, is rotated manually or by a motor through a friction clutch 41 and transmission gearing, the clutch 41 is disposed in a part of the casing which encloses the gearing and is loaded by spring discs 43 disposed within the circumference of the friction clutch discs. As shown, the claw 14 is connected to a drum 12 rotatable in the casing member 10 by splines 15 of less width than the grooves 13 in the drum, and is connected by a torsion spring 17 to a sleeve 16 having splines fitting the grooves 13. Within the sleeve 16 is a member 21 carrying friction blocks 25 engaging the sleeve and having helical slots 24 engaged by rollers 27 carried by a shaft 29. A flange 30 on the drum 12 carries a planet wheel 33 meshing with an internally toothed ring 34 and with the toothed hub 35 of a disc 36 connected by the friction clutch plates 41 to a toothed wheel 47, which engages a pinion 61 driven through transmission gearing by an electric motor 62. The wheel 47 can also be driven from a handactuated shaft 51 through gears 50, 49 and a hollow shaft 48 connected by a pin 56 to the shaft 29. On rotation of the gear 47 by means of the motor 62 or the shaft 51, axial movement of the claw 14 into engagement with the engine is effected by the interaction of the rollers 27 with the helical slots 24, and the claw is driven through the friction clutch 41, planet gear 33 and drum 12. If the claw 14 clashes with the corresponding engine member, rotation of the sleeve 16 tensions the spring 17 and this turns the claw into correct engagement. Specification 529,553 is referred to.

Title: A process for preparing fine coal from a dilute coal slurry
IPC: B01D36/00
Filed: 1960-05-09
Abstract: 912,148. Filters; gravity-separation apparatus STAMICARBON N. V. May, 9, 1960 [May, 8, 1959], No. 16345/60. Class 46. Dilute slurry (e.g. of coal) is fed into at least one settling cone 2 whence thickened slurry passes through a valve 4 regulated by a control 6 to maintain constant the level in the feed tank 5 into which the thickend slurry falls. The slurry is pumped (8) to at least one froth flotation machine 9 whence coal concentrate is passed to a collecting tank 10 from which it passes through a level-controlled valve 12 to the troughs 19 of a number of drum filters 13. When the level in tank 10 is below a, a few filters, operating at the lowest r.p.m. suffice. As the amount of concentrate increases, more filters are manually put into operation until at level a, a level-controlled (15) r.p.m. controller 14 is actuated to increase the r.p.m. of the drums. At level b, the r.p.m. is at its maximum (e.g. 2 r.p.m.) for maximum filter capacity. Thereupon a level-controlled (16) valve 17 is opened to add water to the thickened slurry in tank 5, the admission of thickened slurry from cone 2 being simultaneously reduced by valve 4. Such re-diluted slurry produces less concentrate from the plant 9, with consequent lowering of the level in collecting tank 10. The degree of opening of valve 17 depends on the rise of level above b in tank 10.
