Title: Improvements in apparatus for regulating physical quantities or qualities
IPC: G05D13/00
Filed: 1923-08-22
Abstract: 227,882. Roucha, E. Aug. 22, 1923. Fluid-actuating mechanism.-In a transmission system, a servomotor is controlled by an electric relay, a variation in the interval between the impulses in one direction or the other, introducing an equivalent operation of the servomotor. The system may be employed for controlling the speed of a turbo-generator in accordance with output and intake water-level or steam pressure or the draft of a furnace in accordance with the steam consumption &c. In an arrangement for controlling a turbo-alternator 134, 136, Fig. 1, periodic flexing of a spring 34 connected to a lever 24 is effected by a cam 44 driven by a synchronous motor 48 connected to the mains 22. The lever 24 is connected at one end to a rod 12, the movement of which is controlled jointly by the dynamometer 14, 16 and a float 2 in the turbine intake, and at the other carries a contact 28 in circuit with a battery 56, electromagnet 60 and make and break contacts 50, 52. Momentary closure of the circuit disengages a detent 68 from beneath a lever 70, Fig. 2, whereby a head 82 is depressed by a spring 78, resetting being afterwards effected by a cam 73. Beneath the head 82 the triangular end 104 of a flexible arm of a bell-crank 102 is reciprocated transversely by a synchronous motor 88 in phase with the motor 48. On depression of the head 82, the member 104 engages centrally between the levers 106, 108 or alternatively on one or other of these levers, depending on the phase of the impulse over the circuit 58, whereby the piston valve 116 is moved to the right or left. Pressure. fluid is admitted to the servomotor 126, whereby the governor-controlled valve of the turbine is operated through a spring 130 to regulate the speed of the turbine 134. In operation, the moments at which the electric impulse is transmitted to the magnet 60 varies within the regular interval determined by the rotation of the cam 44. according to the balance of this dynamometer and the float against the varying tension of the spring 34. In a modification, the control bv the float 2 may be replaced by a hand-set adjustment. and the dynamometer may be connected to a longitudinally movable rod which is unlatched by the periodic excitation of the electromagnet 60. When the system is applied to the regulation of the furnace draft in accordance with steam consumption pressure differences on the opposite sides of constrictions in the steam and air supply pipes are communicated respectively to the opposite sides of two diaphragms on the rod 12, and the servomotor adjusts a damper in the flue.
