Title: Improvements in or relating to the separation of coal from waste by flotation
IPC: B03D1/24
Filed: 1922-10-28
Abstract: 191,383. Diehl, L. H. Jan. 7, 1922, [Convention date]. Flotation processes and apparatus. - An improvement in the process for recovering coal from waste by means of flotation carried out in a vacuum as described in Specification 188,325, consists in so introducing the coal-water mixture, to which the requisite floating agents have been added, into the apparatus that a rotary movement is imparted to the mixture. Apparatus for carrying the improved process into effect comprises a double conical vessel 1 into which the mixture is supplied by the pipes 4, 5 in a tangential and slightly upward direction so that the mixture assumes a swirling movement inside the vessel. The separation is enhanced by a regular pulsation of the liquid surface brought about by periodically operating the tailings discharge valve 17. This forces the clean floated coal over the rim of the discharge pipe 10, from which it passes through the valve 21 into the launder 23. The tailings sink in the discharge pipe 7 and pass through the valve 17 into the launder 22.

Abstract: 795,019. Change-speed gear. AUTO TRANSMISSIONS, Ltd. Dec. 4, 1956 [Jan. 6, 1956], No. 515/56. Addition to 739,126. Class 80 (2). The overdrive planetary gearing for motorcars of the parent Specification comprises a driving shaft a and carrier e with planet gears f meshing an internally toothed driven annulus n and a reaction sun gear d on a sleeve c carrying a clutch-brake member i, a free-wheel h connecting the driving shaft and driven annulus. The reaction sun gear d and its associated sleeve c are slidable axially on the driving shaft a by the reaction of the gearing to the transmission of torque through its gear wheels, which are helically toothed. Engagement of the clutchbrake member i with a surrounding casing m or the annulus n by hydraulic pressure &c. is thus assisted. This construction is modified by splining the clutch-brake member i to the reaction sun gear sleeve c, so that the sleeve can slide leftwards in the Figure with respect both to the clutch-brake member i and the driving shaft a. A collar p prevents the reaction sun sleeve c moving rightwards with respect to the clutchbrake member i. The interaction of the helically toothed gears is now effective only to increase the grip of the clutch-brake member i with the annulus n, when the car is driven in reverse or during forward overrunning.

In a machine for rolling metal discs 14, Fig. 2, indexed between radially reciprocating rolls 13 backed by platens 15, relatively movable co-operating wedges 34, 35 are provided to effect automatic adjustment of the roll gap. The platens 15 are mounted on a carriage 12 comprising two parts pivoted together and reciprocating over guides 11 of the machine frame 10 under the action of an oscillating beam lever 16 which is pivoted at 17 to the machine frame. The rolls 13 are carried by pivotally connected levers 24, one of which is coupled to the beam 16 at a mid-point so that the rolls 13 move at half the speed of the carriage 12. Adjustment of the platens 15 is provided by four bolts 29, Fig. 3, which are mounted for axial adjustment by worm-driven nuts 43 actuated from hand wheels 46 and acting against the pressure of springs 38 which urge the platens 15 apart. Automatic pass release for the return stroke of the rolls is provided by toothed plates 32, 33 which normally have the flat crowns of their teeth in engagement during pass setting. Both plates reciprocate with the carriage but one plate 32 has limited movement and is engaged by a fixed stop 47 at the end of each stroke to bring the teeth into engagement and release the bolts 29 so that the springs 38 are free to separate the platens. The pass setting is restored at the end of the return stroke by a similar fixed stop 48 which moves the plate 32 back to its original position. The automatic pass adjustment is obtained as required by the relative movement of a pair of wedges 34, 35, one of which 35 has limited movement on the carriage 12. When the pass is to be reduced a stop 51 is moved into the path of the wedge 35 by means of a pneumatic cylinder 54 so that the wedges act to compress the springs 38 and bring the platens 15 and rolls 13 closer together. The indexing and clamping mechanism for the work is described in Specification 771,804.
