Application filed January 5, 1916, Serial No. 70,552. Renewed June 14, 1919. serialno. 304,277.

To all whom it may concern:

Be it known that I, Goeu CONSTAN- TINESCO, a subject of the King of Roumania, and residing at The Haddon Engineering Works, Honeypot Lane, Alperton, Middlesex, England, have invented certain new and useful Improvements in and Relating to Fluid Wave Transmission, of which the followin is a specification.

In fdrltish Patents Nos. 9029 of 1%38 of 1914, a method and apparatus are described for transmitting energy by wave.

connecting the generator with the receiver,

or working apparatus should contain different kinds of fluid at different parts. If the leakage from the pipe is zero, the ordinary diaphragm, or even the surface of the two liquids, may be sufiicient to secure the separation of the two fluids; but if leakages have to be taken into account, it will be seen that this method will not be suflicient.

The object of the present invention is, in a system of wave transmission of energy, to utilize different fluids in different parts of the system, and to provide means for separating the fluid columns at any given point, so that for instance oil may be used in the generator, and water inthe pipes between the generator and the receiver or receivers.

The invention consists in the use of a separator comprising a floating piston or diaphragm, controlling the supply of the liquid to the columns on its two sides, in such a way that when the leakage is greater on one side than the other, causing the pressure on one side to be greater than on the other, the movement of the piston or diaphragm toward the side on which the pressure is lower diminishes the oil supply, and eventually cuts it off, while if the leakage occurs on the oil side, the movement of the piston toward this side controls and ultimately cutsofi' the water supply.

In the accompanying diagrammatic drawing, which represents a separator, used on a wave transmission line intended to operate rock drills, in which there is considerable leakage of water, for the purpose of flushing 1913 and outthe hole, the water line is connectedto the separator at a, and the oil line at b, the 011 line being connected to a wave generator working with oil, and having a leaky piston.

The water is supplied through the pipe/0,

and the oil is supplied through thepipe d,

from constant pressure devices. As the pulsations in the wave transmission line vary I from a minimum to a maximum, each time the pressure drops below a certain value on account of leakage, the check valves 6, 7",

open inward, and some water or oil woulc enter the line, making up the leak. I y The oil and water are constantly separated by the floating piston g,'which is fixed to a central rod. it, having at itsends ma-' chined surfaces is, Z, movingxin'the ends of the chamber of the separator. Apertures m, a, are provided, connecting the central portion of the, chamber on each side with the end spaces.

The operation of the above described device is as follows :Assuming that the leakage on the waterside is excessive, compared with the leakage on the oil side, the natural tendency of the floating piston 9 will be to move toward'the water side, that is, to the left. During this movement, the piston valve [Will gradually cut 05 the oil supply from the check valve f, to the right hand chamber of the separator. The oil supply through the valve f is thus gradually stopped, and the mean position of the piston is prevented from moving farther in the direction of the Water line. The constant leakage on the oil side has a tendency to bring the piston back, as the mean pressureon the oil side would decrease.

The apertures m, "It, are provided In order ,to secure a permanent communication be tween the separator chambers and the end spaces, and so avoid pressures whichmight occur in these end spaces, due to leakage.

around the pistons 70,1. The piston valves 70, Z, should be so proportioned that the normal stroke of the floating piston about its mean position, due to the pulsations in the pipe line, is still secured, even when the piston g is in the position in which the check valves 0 or f are completelyclosed,

The outlet from the separator may be in any required direction, and the main piston ma if desired be provided with leather cups its or other packing, in order to prevent filtration of water to the oil, or vice versa.

It Will be seen that in certain conditions it may occur that the .water leakage is always in excess of the leakage of oil, and in such cases it is possible to dispense with one end of the controlling piston. In this case, how- 7 ever, care must be taken that the separator is fitted with the right ends toward the oil and water, respectively.

If the Water line is connected to other generators workin parallel, it is necessary that both piston va ves should be provided in order to prevent the piston reaching the end of the casting.

If desired, the inertia effects of the oscillating piston may be annulled by balancing it by'means of springs. The separator will thus perform the functions of a condenser.

If, however, the section of the piston g is- I claim as new and desire to secure by Let ters Patent is 1. In a fluid wave transmission system a separator comprising in combination a chamber, a piston in said chamber, connections to a fluid wave transmission line at each end of said chamber, a passage for the supply of fluid at one end of said chamber, a valve controlling said passage, an axial extension on said piston having a cylindrical valve also controlling said supply passage, said cylindrical valve being adapted to close said supply assage when the piston is at the end of t e chamber remote from said passage, as set forth.

2. In a fluid Wave transmission system a .separator comprising in combination a chamber, a piston in said chamber, connections to a fluid Wave transmission line at each end of said chamber, passages for supply of fluid opening into each end of said chamber, valves controlling said passages, axial extensions from said piston, cylindrical valves 011 said extensions controlling said supply passages and adapted to close one of said passages when the piston is toward the other end of said chamber, as set forth.

In testimony whereof I have signed my name to this specification.
