A machine for stacking or unstacking boxes &c. comprises an elevator for raising a stack past retaining means and lowering the lowermost case on to discharge means in unstacking, and for raising individual cases past retaining means in stacking, the support on release of the boxes being controlled by the elevator whether it carries a box or not. The machine comprises identical frameworks on opposite sides of a through conveyer 22 the framework supporting guide rods 96, 98, 100, 102 on which are vertically slideable carriages 116 having depending members 104, 106 bearing lifting fingers 118, 118a,. 120, 120a. Horizontally slidable stops 74, 76 and retaining dogs 86, 86a, 88, 88a are mounted adjacent the - conveyer and above single box height respectively.  In stacking, boxes advance in the direction S, Fig. 1, and operate switches causing a stop 66 to check following boxes and a time delay device to function. Each box is stopped by the members 74, 76 and the time delay device initiates raising of the carriages 116 so that the fingers 118, 118a, 120, 120a, lift the crate past the dogs which then project to retain the box while the carriages descend. The carriages operate switches to permit entry of the next box and the cycle is repeated, each box raising that above it and the dogs being withdrawn just prior to a rising box reaching them. Finally the uppermost box operates a switch causing withdrawal of the dogs 86, 86a, 88, 88a, and descent of the stack on to the conveyer for discharge. In unstacking the conveyer direction is reversed and an incoming stack is stopped by angles 150, 152, the members 74, 76 being withdrawn. Following stacks are checked by a stop 66a and the carriages raise the entire stack above the dogs. Horizontally slideable opposed bars 166, 168, grip the box above the lowermost and the latter is lowered on to the conveyer by the carriages for discharge. The dogs advance to support the stack and the bars 166, 168 withdraw. The carriages again rise to engage the lowermost case, lower the stack one box height, and the cycle repeats.

Abstract: 692,402. Fluid-pressure servomotor control systems. VENNING & CO., Ltd., J. Sept. 26, 1951, No. 22543/51. Class 135. In a hydraulic system for operating machines, e.g. presses for synthetic plastics, and comprising a threethrow H.P. pump 6, Fig. 1, in series with an L.P. centrifugal pump 7, both pumps being disposed in an oil tank 3 and driven by an electric motor 1 mounted on the outside of the tank, the spring-loaded inlet valves 32, Fig. 2, of the H.P. pump are opened through spring-loaded tappets 27 when the discharge pressure of the H.P. pump reaches a predetermined value. The tappets are raised by plungers 36 the supply of pressure oil to the undersides of which is controlled by relays 14 secured to the wall of the tank and connected by pipes 16 to the H.P. pump discharge and having outlets to the plunger cylinders and the tank. Each relay comprises a spring-loaded piston 39, Fig. 3, formed with bands 51 controlling the flow of pressure oil through grooves 53, 54, 55 in the piston blocks 52 and connected respectively with the plunger cylinder, the tank and through passages 56, 57 with the high pressure inlet 38 to which the pipe 16 is connected. When the discharge pressure reaches a certain value, dependent on the loading of the spring 40, the piston moves to the left and permits the flow of pressure oil through the grooves 55, 53 to the plunger cylinder so as to raise the plunger and its tappet 27 to open the inlet valve 32. When the discharge pressure falls, the piston moves to the right and oil returns from the plunger cylinder through the grooves 53 and 54 back to the tank. In a modification, the spring 40 is replaced by a lighter spring and the piston is loaded additionally by a plunger subject to the discharge pressure of the L.P. pump. In a further arrangement, the spring load is varied by a piston 63. Fig. 5, the pressure upon which can be varied from a remote position by a grease gun controlled by the machine operator.

Title: Improvements in flotation of fine refuse coal
IPC: B03D1/02
Filed: 1937-08-17
Abstract: Fine refuse coal, e.g. anthracite culm, of 3/32 inch or less, is cleaned by subjecting it to froth flotation in froth flotation cells under conditions which will produce a concentrate having a high percentage recovery of the low ash coal but of relatively low grade, and subjecting the concentrate to classification, e.g. by screening, and rejecting the finer material.  The concentrate may be classified into two or more sizes, the finest size being rejected and the intermediates, if desired, cleaned by flotation.  In the preferred method of treatment the coal is floated in a series of cells with progressive addition of reagents, and only the concentrates from the later cells are classified.  For example, anthracite culm after conditioning with sodium silicate is floated first with a frother consisting of a mixture of paraffin alcohols having 7-10 carbon atoms and hydrocarbons, as described in Specification 446,418, and then in later cells with additions of kerosene or kerosene and frother.  The concentrates from the first three cells are not further treated and may be kept separate or mixed, that from the fourth cell is sized into two or three grades, the finest being rejected and the intermediate, in the case of three grades, cleaned by flotation, and the concentrate from the fifth cell is screened into two grades and the finer rejected.  Specification 446,418 is referred to.
