Abstract: 306,870. Marks, E. C. R., (Northern Equipment Co.). Nov. 25, 1927. Divided on 312,374. Regulation, automatic.-In apparatus for automatically actuating a boiler feed valve to maintain a fixed ratio between the water input flow and the steam output flow, flow meters 57, 58 on the feed pipe 2 and steam pipe 54 contain resistances placed in the arms of a Wheatstone bridge having fixed resistances 30, 31 in its ratio arms, and a relay switch 32 connected across the bridge controls the flow of a current through a solenoid 19 around the magnetized stem of the feed valve 3. The resistances in the meters consist of rods dipping into mercury, which changes in level in accordance with changes in the flow of the steam or water. The flow of current through the solenoid and the consequent operation of the feed valve may be further controlled by a resistance 4 placed in an arm of the bridge and varied in accordance with the boiler water level. The resistance 4 consists of rods dipping into mercury the height of which varies with that of the boiler water. A variable resistance 26 depending from the arm of the feed valve and placed in the bridge opposite the resistance 4 maintains a definite position of the feed valve corresponding to a certain height of boiler water level.

A dispenser for dispensing measured quantities of liquid comprises a measuring chamber formed within a tube 1 having inlet and delivery ports 11, 14 opened and closed by valve discs 16, 17 mounted on a spindle 15 and biased apart by a spring 18. Liquid, e.g. wine, flows through an inlet passage 12 from a barrel &c. and fills the measuring chamber. The spindle 15 is raised by moving the handle 23 against a leaf-spring 24 allowing the valve disc 16 to be pushed upwards by the spring 18 until it seats over the inlet 11. Further upward movement of the spindle allows the central bore of the valve disc 16 to be sealed by a shoulder 20, and the valve disc 17 to be lifted from its seat 13, permitting the liquid to discharge into a vessel held over an anti-splash sleeve 31. A spider 27 is provided for guiding the spindle, and may be constructed from P.T.F.E. along with the valve discs.

Abstract: 1314982 Triggering controlled rectifiers BROWN BOVERI & CO Ltd 30 July 1970 [1 Aug 1969] 36883/70 Heading H2F In a controlled rectifier system for supplying an intermittent load, or a load which produces a reverse voltage, the load voltage is compared with the instantaneous value of the alternating input voltage at an adjustable tapping on a member energized by said input voltage and is turned on so as to provide a triggering pulse or further triggering pulse for the controlled rectifiers. As described, a load such as a battery or D.C. motor produces a reverse voltage U5. This voltage is supplied to terminal B (Fig. 3) where it is compared with the alternating voltage at A obtained from the tapping of a potential divider or an ajustable secondary of a transformer connected across the supply. When the voltages at A, B have the polarity shown, the multi-vibrator 9, 10 oscillates with an amplitude proportional to the potential difference. The resulting pulses are rectified and the resulting uni-directional potential at C, D is fed to a trigger pulse generator of unspecified type so as to provide a trigger pulse at t4 which may be additional to the normal trigger pulse at t2. The rectifying system (Fig. 1, not shown) may comprise a bridge of two thyristors and two diodes or may be a conventional bridge or centretapped circuit.
