Title: Automatic regulating and intermitting or flushing valve
IPC: F16K31/18
Filed: 1922-07-27
Abstract: 203,474. Barlow, T. July 27, 1922. Levels, regulating. - The flow of liquid from a chamber to a balancing bucket is controlled by a valve which is actuated by a float slidably mounted on a rod but with its upper and lower levels determined by adjustable stops on the rod. The outlet A from a chamber B is controlled bv a valve C on a lever system which includes a balancing bucket D. Liquid is supplied to the bucket by a pipe I attached to a float F. The float slides on a rod H having adjustable stops G and an adjustable valve plate K for the inlet opening of the pipe I. As water rises in the chamber B, the float rises to its upper position and the plate K closes the pipe I. Further rise in the water level floods the float and lowers it, so that the inlet to the pipe I is uncovered and water flows to the bucket D which when so weighted falls and raises the valve C to discharge the contents of the chamber B. When the level in this chamber falls sufficiently, the float F and bucket D discharge their contents and the valve C is closed.

Abstract: 224,604. Jenkins, A. J. Oct. 19, 1923. Drawings to Specification. Determining distances acoustically.-A wireless-transmitting main station is connected by land lines with two or more sound-emitting substations. In response to an electric current from the main station, a substation emits a detonator, bell, or like signal, which acts upon a microphone associated with a land line and so causes the emission of a wireless signal from the main station. By timing the interval between the arrival of the two signals a ship can find its distance from the substation and the operation is repeated with a second substation to enable the ship to find its position. In the case of aircraft, three or more substations, not in the same straight line, will be required.
