Specification of Letters Patent.
Patented Mar. 23, infill Original application filed November 18, 1916, Serial No. 132,027. Divided and this application filed July 23,
Lane, iilperton. in the county of Middlesex,
England. now residing at lVestoe. Stanlev avenue. Al ierton in the countv oi Mlddies-ex, England, have invented certain new i and use ful improvements in and Relating to Liquid l'l ave 'liransmission, of which the following is a specification.
The present invention relates to wave transmission through liquids, that is, transmission of energy by a series of periodic variations of pressure and volume traveling along a liquid column or columns as described in the specification tierial No. (33762, filed 27th November, 1915. I
The object of the invention is to provide means whereby the line can he fed with trcsh liquid without interfering with the wave motion, or with the operation oi generators and receivers on the line.
The invention consists in feeding a wave transmission line by means of a pump, pumping into a capacity, which communi= cates with the line through a pipe whose length is a quarter of the wave length of the waves in the tansmission line at the periodicity used.
The invention also consists in connecting the feeding quarter Wave length pipe to the line at a point, at which the pressures vary from maximum to minimum values.
The invention also consists in the improved means for feeding a Wave transmission line hereinafter described.
Referring to the accompanying drawings:
The figure is a diagrammatic drawing showing the application of the invention to a single phase Wave transnnssion lmo.
In carrying the invention into effect as shown in the figure, a single phase generator a produces a series of periodic variations of pressure and volumewhich travel along the transmission line I) and actuate single phase motors or other apparatus one of which is shown at 0. Fresh liquid'is pumped into the strong vessel d by a suitable pump,'the
vessel d being connected to the main trans- Serial No. 246,396.
mission line b by a pipe a which is of such length that the phase ditl'erence between its Elucha pipe is termed a quarter wave length pipe. From the analogy of sound waves passing along a hotly of liquid it will be understood that a phase ditierence ol' All is a phase difference of 90, that is to say, a quarter of 360 which is the full wave length.
According to one example, as applied for instance to a high trequency line in w ich the wave length. is of about 2 meters, We provide a pump pumping-oil into a capacity of say 10 liters, "from any suitable supp The capacity is connected through a pipe which may be oi any diameter, with the transmission line, connecting with this tine at a point close to the generator. of pipe in the case considered will be half a meter. In order with this arrangement to supply additional oil to the line, it is merely necessar to keep the pump Working, pumping into t e capacity which is in com munlcation with the line. If it is desired to feed the line at points remotevirom the generator, all that is necessary is to connect a pump, capacity and quarter, Wave length pipe to the line, at points at which the pre sure in the line rises to the maximum and falls to the minimum values.
The points at which the pressure rises to a maximum and falls to a minimum are points situated at distances equal to the wave length and all multiples of the Wave length from the generator. The wave length is detern'iined when the elasticity of the liquid employed and the period oi the impulses are known, the transmission of energy being ing of the oil into the capacity, and the passing of this oil from the capacityto the line will take place under a constant pressure The length.

Having now described my invention, What I claim as new and desire to secure by Letters Patent is 1 Apparatus for feeding a wave trans- 5 mission line comprising in combination a capacity or strong vessel filled with liquid, means for introducing liquidinto said capacity, and a pipe connecting said capacity to said Wave transmission line, the length 10 of the pipe being such that with respect to the wave in the transmission line the phase difference between its ends is g as setforth.
capacity or strong vessel filled with liquid, means for introducing liquid into said capacity, and a pipe connecting said capacity to said wave transmission line, the length of the pipe being such that with respect to the Wave in the transmission line the phase difference between its ends is 5' said pipe being connected to said Wave transmission line at a point at which the pressures vary from maximum to minimum values, as set forth.
In testimony whereof I have signed my name to this specification.
