Abstract
1984. Herzfeld, J. Jan. 24. Siphons.-Relates to double-bend siphons and consists in the provision of a pressure-compensation pipe r to prevent the escape of the seal in the vent-pipe h. When several siphons are used in one tank, a single vent pipe is connected through valves with each siphon, and each pipe i, provided to carry off the water in the bend d after each discharge, is connected to the other similar pipes.
