Abstract: 565,016. Fluid-pressure servomotor-control systems. NORTON, R. M. April 7, 1943, No. 5576. [Class 135] [Also in Group II] In a jig having a float operated by a relay for washing coal or other materials in which in order to ensure that the relay is operated upon the level of the refuse bed varying, whatever the amplitude of pulsation of the water, a device, e.g. a dashpot, operative at any level of the refuse bed is provided for retarding or damping the upward movement of the float without materially reducing the rate at which the float will fall. A gate 5 controlling the discharge of refuse through the opening 3 is linked to a rod 6 pivoted to a pivoted weightcontrolled lever 7, the other end of which is connected to a piston-rod 9 connected to a piston 10 in a cylinder 11. The entry of steam or air by a pipe 13 to the cylinder 10 is controlled by a pilot valve 14 rigid with a relay arm 18. A float 16 carried by parallel-linkage consisting of arms 17 and 18 and vertical arm 19 is provided to sink through the material and being stratified by the pulsation of the water until it rests on material of predetermined density so that it moves up and down as the layer of material of density equal to or greater than the value increases or decreases in depth, and the float also moving with the pulsating water. The arms 17 are rigidly connected to rod 20 carried in brackets 21 fixed to a girder 22 and arms 23 carrying weights 24 project rearwardly from the arms 17. At one end of the rod 20 a caliper rod 25 is fixed so that it rocks with the rod and is provided at its lower end with two bosses receiving screws, the relay arm 15 being moved whenever one of these screws engages it. The float is damped by a dashpot in the form of a cylinder 31, Fig. 4, in which moves a piston 32 having an opening 33 controlled by a non-return valve 34. The piston-rod 35 is connected to one end of an arm 36, the other end of which is keyed to the rod 20. A byepass valve 37, Fig. 5, controlled by a valve 38 which closes an opening 39 to a greater or less extent connects the ports of the cylinder on two sides of the piston. When the float 16 and, therefore, the piston-rod 35 moves downwardly, the liquid in the cylinder will move freely through the opening 33, but when the float moves upwards the valve 34 will shut and liquid will be forced through the byepass 39 which moves upwards ; the movement being thus damped.
