Abstract: 1,056,311. Valves. CLEAR HOOTERS Ltd. Feb. 1, 1965 [Feb. 4, 1964], No. 4616/64. Heading F2V. [Also in Division G2] A control valve for varying the degree of vacuum applied to a servomotor comprises a bracket 10 carrying a housing 11 having a hollow spigot 29 connected at 27 to a source of vacuum and a port 33 connected to a servomotor. A diaphragm 15 is mounted at 14 in a recess the housing and has a central sleeve 16 surrounding the spigot, the top of the sleeve providing a seat for the head 24 of a closure member 21 adapted to obturate the end of the spigot, the closure member being carried on a light leaf spring 22 which urges it towards the closed position. A beam spring 18 supports the diaphragm by means of a flange 20 provided on the latter, the spring being fixed at its righthand end (not shown) and engaging a face cam 35 at its other end, the cam being pivoted at 36 and rotatable by a lever 42. In operation, air is withdrawn from the servomotor via pipe 32, chamber 31 and passage 28 until the pressure difference across the diaphragm balances the load applied thereto by the beam spring. To increase the vacuum applied to the servomotor, handle 42 is rotated to increase the load on the diaphragm and thereby unseat member 21 from the spigot. The vacuum in chamber 31 then increases until the pressure difference across the diaphragm again balances the load of the beam spring. To reduce the vacuum, the load of the beam spring is reduced and thus the diaphragm moves away from the head 24 to admit air at atmospheric pressure until balance is restored. The port 27 may connect with the induction manifold of an engine and the servomotor may control a valve or flap in a heating system.

Filed: 1920-02-23
Abstract: 161,781. Hewens, C. J. Feb. 23, 1920. Automatic-feed weighers.-In an automatic liquid-weigher, an electromagnetic operating means for the feed valve is placed in and out of circuit by primary and secondary switches at the commencement and completion respectively of the weighing operation, and a tertiary switch operated by the electromagnetic means maintains this means operative until the secondary switch functions. On depressing the primary switch 11, of the push button type, a solenoid 6 is energized from the mams 9, 10. The core of the solenoid raises the feed valve 1 and also throws over and thus closes the tertiary switch 12 so that the current through the solenoid is maintained when the button 11 is released. When the requisite weight has been delivered through the feed valve 1 to a receptacle on the weighing platform (not shown), the steelyard or other moving part of the weighing machine breaks the circuit through the secondary switch 13, preferably of the mercury type, thus de-energizing the solenoid 6 and allowing the valve 1 to fall and cut off the feed. The core of the solenoid 6 is connected to the tertiary switch 12 through a loose spring-pressed sleeve 14 to allow the core greater upward movement than would otherwise be permitted by the throw of the switch.
