Title: Apparatus for regulating fluid flow
IPC: G05D11/13
Filed: 1966-12-13
Abstract: 1,130,790. Automatic flow control. CROWN CORK & SEAL CO., Inc. Dec. 13, 1966 [Dec. 17, 1965], No. 55857/66. Heading G3R. The difference between electrical analogue signals corresponding to two rates of fluid flow is integrated electronically and utilised to restore the rates of flow to a desired ratio automatically. In Fig. 1, water and syrup are respectively applied through conduits 10 and 12 and mixed together in a cooling tank 14 associated with a soft drink bottling plant (not shown). The flow of water is maintained substantially constant by a regulator 18. Electrical signals corresponding to the rates of flow are obtained from turbine water flowmeter 22, producing pulses and an electromagnetic syrup flowmeter 40, producing AC. After linearising if necessary, and converting to DC. analogue form, the signals are compared at 32 and a potentiometer 48 set so that they are equal when the rates of flow are in a desired ratio. Any deviation then produces a difference which is applied to an adjustable integrating amplifier 52 controlling a pneumatically operated valve 38 in the syrup conduit to restore the flow ratio. If the control signal becomes excessive an alarm 60 is operated, and, if the level in tank 14 rises to a predetermined value, a detector 64 closes valves 20, 38 to cut off the fluid supplies and a relay 68 is operated to disable the input to amplifier 52 and discharge the intergrating capacitor in amplifier 52.

The brake is normally held by springs and is adapted to be released by hydraulie means to permit free fall of the load. Alternatively, the drive input may be by way of the planet carrier, and the sun gear may constitute the braked member. An hydraulic fluid circuit for releasing the brake comprises a supply pump 3, a flow regulating and pressure release unit 4, a manually operable control valve 5 and an actuator 2 to which hydraulic pressure is applied in order to release the brake. The degree of closure of the control valve 5 adjusts the speed of free fall by varying the pressure at the brake actuator 2. A metering pump 7 is coupled to the planet carrier and this produces a negative feedback which maintains the winch speed substantially constant at a value depending on the setting of the control valve 5. For emergency free fall, a manually operable selector valve 8 is provided.
