Title: Improvements in apparatus for the automatic control of a variable condition
IPC: G05B11/01
Filed: 1934-12-06
Abstract: 453,545. Automatic control systems. KENT, Ltd., G., 199, High Holborn, London, and IVANOFF, A., and HOWARD, G. P. E., Biscot Road Works, Luton, Bedfordshire. Dec. 6, 1934, No. 28147/35. Divided out of 433,369, [Group XXIX]. [Class 38 (iv)] Temperature &c.-In. maintaining a variable condition at a predetermined value two electric motors 7, 8 are coupled through differential mechanism 31, to a device 32, controlling the variable, e.g. a steam valve in a temperature control system and contact mechanism is operated at regularly recurring intervals wherebv one or other motor is subjected to an impulse for a duration according with the duration of the condition from the predetermined value and also to an impulse in accordance with the second differential of the deviation ; the motor actuated depends upon the sense of the deviation, or of the second differential respectively. According to the invention the contact mechanism comprises a member 2 actuated in response to changes in the variable by a cam 11 and a member 23 which is caused to occupy a position, with reference to a datum, corresponding with the second differential of the deviations. With these two members, which carry contacts electrically connected to a source of voltage 9, co-operate respectively pairs of contact arms 3, 4 and 27, 28 which are connected through the respective motors 7, 8 to the source. In order to obtain the desired movement of the member 23 a further member 15 is connected through a friction clutch 14 and an arm 13 to the member 2 and through a second friction clutch 22 and arm 21 to the member 23. Brakes 19, 30 are adapted to hold the arms 13, 21 stationary when arms 16, 17 and 27, 28 are operating. At the end of each period, during which the members 2, 15, 23 have been free to move together in accordance with changes in the variable, the following sequence of operations takes place : (1) Cams 11 are moved to permit springs to close the arms 3, 4 on to contact member 2 ; the first impulse is thus given to the motors and the cams open the arms 3, 4 again ; (2) The brake 30 is applied ; cams 29 cause the arms 27, 28 to move member 23 to its datum position, and the second impulse is given to the motors; (3) The brake 30 is released, the brake 19 applied and cams 18 cause the arms 16, 17 to bring the member 15 to its datum position and so give arm 23 a deflection equal and opposite to that the arm 15 ; (4) Brake 19 is released. Succeeding deflections of the arm 23 at the time the impulse is given to the motors will represent the difference between the changes occurring in the variable in two successive periods and hence the impulse duration corresponds to the rate of the rate of change, the rate of change being indicated by deflections of the member 15.
