Title: Improvements in or relating to the drying and treatment of finely divided carbonaceous matter
IPC: C10F5/00
Filed: 1921-11-29
Abstract: 193,947. Broadbridge, W., Edser, E., Stenning, W. W., and Minerals Separation, Ltd. Nov. 29, 1921. Flotation processes.-A modification of the process described in Specification 155,875 for treating finely divided coal or other carbonaceous material associated with water consists in suspending the material in sufficient water to make a mobile pulp and subjecting it to vigorous agitation, preferably with aeration, with a flocculating agent such as an anthracene oil, coal tar, or other hydrocarbon liquid, which does not act as a binding medium, in quantity insufficient to form an amalgam but sufficient to coat the particles and flocculate them, after which the flocculated particles are separated from the water and rendered substantially dry by draining or filtration with or without the assistance of pressure but without the production of durable briquettes, the process being preferably carried out at atmospheric temperature. The concentrates may then be coked in a retort, the tarry residue from which may be utilized as the flocculating agent in treating further quantities of the material. When treating coal that has not been previously separated from gangue, the gangue particles are not coated with the flocculating agent and remain suspended in the water with which they are separated from the masses of flocculated coal by draining. Froth flotation treatment may be carried out in a similar manner by using a flocculating agent which contains a small proportion of frothing agents. In this case the coal is floated in the froth and the uncoated gangue remains in the water. Specifications 6863/04, 10475/05, and 151,236 are referred to.

Title: Improvements in apparatus for removing bricks from a press
IPC: B28B13/02
Filed: 1957-10-14
Abstract: 823,651. Removing bricks from presses. RIVERSIDE TOOL & DIE CO. Oct. 14, 1957 [March 4, 1957], No. 31983/57. Class 87(2). Relates to known brick pressing machines in which the product of the compression moulding operation is ejected upwards from the mould and then pushed out to make way for the next charge of material. A charger 18 holding the brick material has forwardly projecting side bars 26, 27 which are spanned by a front padded gripper bar 28 held between trunnions 29, 30 which are eccentric to the shaft of a pinion 32. A rear padded gripper bar 39 has rods 40 which project from it into recesses in a member 25 at the front of the charger 18, where they are spring- loaded. When a brick has been pressed and ejected, ready for removal, a member 44 on a bracket 43 carried by the operating shaft of the brick press operates a micro-switch 46 which operates a soldenoid valve 52 and admits com-  pressed air through a pipe 37 to one end of a cylinder 35, whereupon its piston moves to cause a rack 33 to rotate the pinion 32 counterclockwise so that the gripper bar 28 moves from the position shown in Fig. 4 to that shown in Fig. 5, continuing a short way beyond the bottom of its rotation and thus raising the front of the brick 56. The forwardly moving member 25 causes the rear gripper bar 39 to engage the back of the brick and there is then slight rearward movement of the bar in an upwardly sloping position by reason of the inclined guide rods 40. The brick is thus lifted slightly and is carried to the delivery table held between the gripper bars and without danger of its bottom being scored. At the end of the forward travel of the charger 18 a switch operating member 45 initiates a reverse operation of the piston in the cylinder 35, rocking the bar 28 away from the brick and into a position where it clears the brick on the retraction of the charger. The operation may be fully electrical.
