The rate of i flov'vhor head, of the Siphon depends` upon thedify ference in levelbetween the discharge `tank and the receiving tank. When the liquid `level in the `receiving tank rises to the same `height as the liquid level in the dischargetankgthe Siphon is n balanced and the iiow` ceases, `(but. the flow will be resumed again if the liquidlevel ineither tank is raised above the level inthe other tank. In
the present inventionqthe.,siphonis balanced Without raising the levelof theliquid in the re` ceivng tank to the same height `as the level oi the liquid in the discharge tank. Thisis secured byapplying a bell tube: on the dischargewend ofthe Siphon so that as the liquid level rises `in the receivingtank `and s1`1rrounds,"this` tube the Vair pressure within "the tube' `is graduallyincreased, opposing the flow of the `liquidzand reducing the rate` of flow'until ultimately it Stopped- The position, orheight,` of the liquid in thereceiving'itank` at `which 'the flow Stops depends mainly `upon the head of the Siphonand upon the length of the bell tube ,in which theair pressure is generated by, the` rising l liquid. This i position can readily be determined` so that, if `the liquid level" in the 'dischargetank is `kept `fairly constant, the level to which the liquid will rise in overflow in the receiving tank'avoided. l
`the receiving tank can be predetermined and an Whenthe flow of the liquid through the Siphon is balanced, it can be started again by increasing theheight of` the'liquid in tlie'discharge tank or by lowering the leveloi the liquidin the receiving tank So'that thesystem can be used to automatic cally replace liquid drawn oit `from the receiving tank.

` `Inthe diagram in Fig. an electropneum`atic 4 valve I I is used to control the vent ||4 at thetop of the sip-hon tube `ThisI valve, through the mounting I I2 is connected to the vent I I3 and is provided with an` armature II5, having a `stem I I6 which engages the head ||1 and depresses valve ||9 against spring A|| 8 sothat when the magnet I is energized valve I I9 is open andthe Siphon tube is vented to break the Siphon. Mag` `process is stepped up until sucient air is ex. hausted from thetube so thatupon cooling the when the liquid rises in tank 23 to reach this` bulb, through pipe |28, raises diaphragm |29 to close the circuit at |3I. 'Ihecontroller |3| `and the controller |24 are connected in series so that when both of these controllers are operated at the same time, magnet` is energized, but Vwhen either one is energized andthe other deenergized- .the magnet remains deenergized.
