Title: Improvements in or relating to speed governing systems
Inventor: MITCHELL JOHN MACKENZIE
IPC: G05D13/00
Filed: 1957-07-08
Abstract: 851,539. Fluid-pressure servomotor-control systems. GENERAL ELECTRIC CO. Ltd. July 4, 1958 [July 8, 1957], No. 21588/57. Class 135. To avoid static friction effects of the spool 5 in the sleeve 8 of a pilot valve of a speed governing system, the spool is connected so as to be continuously rotated by the governor. As shown, an increase of speed of the machine driving the flyweight governor 1 will cause the valve spool 5 to move upwardly to allow pressure oil to pass from a sleeve inlet port 16 through a sleeve control port 11 to the underside of a spring-biased singleacting power piston 9, integral with the sleeve and both will move to follow up the valve spool until a lapped condition (shown) is attained. A reduction of speed would cause the valve spool 5 to move downwardly and uncover the sleeve control port 11 to allow pressure oil to exhaust from the underside of the power piston through a sleeve exhaust port 20 and an exhaust port 21 in the power cylinder 10 until the power piston 9 follows up the motion of the valve spool under the action of its loading spring and the sleeve attains a lapped condition. A spring 12 arranged between the end of the valve spool and the sleeve provides a damping effect to increase the stability of the system.

Abstract: 1,214,716. Automatic pressure control. ALEXANDER CONTROLS Ltd. Aug.7, 1969 [May 7, 1968], No.21647/68. Heading G3R. [Also in Division H2] An electrical switch responsive to the pressure on the outlet side of an electrically-operated fuel gas valve controls the setting of the valve through a solid-state relay to maintain the outlet pressure within a desired range. The pressure at the outlet of a fuel gas burner valve 12, Fig.2, is applied through a passage 40, Fig.4, to a flexible diaphragm 37 operating a two-way switch 49 against a spring 57 so that if the gas pressure rises or falls to a predetermined extent above or below a predetermined value, switch 49 closes its contacts to trigger a silicon controlled rectifier to energize a single-phase induction motor 23 which, through a rack and pinion 19, increases or decreases the opening of a valve 14 as necessary to restore the pressure between the limits which are adjustable by screws 55, 56. Operation of the motor in the appropriate direction is ensured by a change-over switch (not shown) operated by a member 59 when switch 49 passes an intermediate position between its contacts. A limit switch (not shown) cuts off tfie electrical supply when the valve is fully open. If the electrical supply fails, an electromagnetic clutch 24 between motor 23 and rack and pinion 19 is de-energized so that valve 14 is closed by springs 15.

Abstract: 1434912 Automatic voltage control LUCAS ELECTRICAL CO Ltd 27 April 1973 [10 May 1972] 21689/72 Heading G3R A road vehicle battery charging system, using a switching transistor in series with the field winding of an alternator to regulate the charging voltage, includes a voltage sensing arrangement such that the alternator is normally regulated in accordance with the battery voltage, but disconnection of the alternator output lead results in regulation at a higher voltage in accordance with the alternator output. As shown, a battery 15 is charged from an alternator 11 over an output line 13. A voltage sensing lead 21 is connected to earth through a diode 22 and potential divider 23, 24 which is also connected to a Zener diode 26, the breakdown of which controls the switching of transistors 29, 31 in series with the field winding 32. If the output line 13 breaks, rising alternator voltage causes conduction of diode 20 connected through auxiliary rectifiers 16, and diode 22 is blocked. Regulation thus takes place at a higher level because of the potential drop across resistor 25. If the sensing lead 21 breaks, transistors 29, 31 receive no base bias and the alternator remains off.
