Title: Improved means for the automatic regulation of the action of machines for the continuous processing of materials
IPC: F26B25/22
Filed: 1944-12-05
Abstract: 588,573. Automatic control systems. BRITISH COTTON INDUSTRY RESEARCH ASSOCIATION, and JONES, E. H. Dec. 5, 1944, No. 24251. [Class 38 (iv)] [Also in Group XXXVII] Humidity.-An apparatus for the automatic regulation of machines used in the continuous processing of materials, in which the moisture content of the material produces a change in the potential in part of an electric circuit, from which a series of electric charges are obtained, which react through a thermionic valve circuit to control the direction of rotation of a motor actuating the regulation of the machinery. In Fig. 1, current dependent on the moisture content of the material passes through potentiometer resistance 11 and the potential difference between the ends of variable portion 11a is applied to condenser C through contacts 12, 13 and 14. The voltage across plates 16a and 16b of condenser C, which discharges through resistance 19, acts between the grid and cathode of triode valve 21 to control the anode current of the latter. Valve 21 forms one arm of the Wheatstone bridge network completed by resistors 24, 25 and 26, the state of balance of which is indicated by the potential difference between 29 and 30 and is a function of the anode current of valve 21 and hence also the voltage developed across resistor 11a. The voltage between 29 and 30 is applied to grid-cathode circuit of gas-filled triode V, the plate voltage of which is supplied by transformer 36. Plate current from V is applied by switch Y to the armature 40 of a D.C. motor which may actuate the speed control device or the supply of steam to the material drying, cylinders. Switches 12, 13, 14, X and Y are of the cam-operated, rotary type mounted on a shaft geared to the machine so as to run at a speed proportional to that of the drying cylinders. With the moisture content of the material at the normal level, the Wheatstone bridge is set to balance conditions by resistor 26. A change of the moisture content produces a corresponding outof-balance voltage between 29 and 30 which causes V-to conduct when the switch Y has been correctly positioned by the cam to cause armature 40 to rotate in the direction necessary to bring about the return to datum conditions of moisture. In Fig. 3 (not shown), a further embodiment is given in which 'all voltages are derived from transformers operated from A.C. mains. Specifications 567,259 and 568,480, [Group XI], are referred to.
