4 Claims. (01. 183-237) This invention relates to a turbulence rectifier across the interior of the tubular member as for controlling fluid passing through a pipe or clearly shown in the drawing. the like, and while the device has been designed An obstruction 13 of ellipsoidal shape interspecifically for use with oil and gas separators, sects the vanes and is supported thereby in a 5 it will be apparent to those skilled in the art that position centrally of the tubular member 9 and 5 it has numerous other applications. about mid-way between the ends of the vanes.

While I have disclosed preferred embodiments of the invention shown in use with an oil and gas separator, it will be manifest to those skilled in the art that many other embodiments may be made and that the device may be employed wherever it has utility. It should therefore be understood that I intend to claim all inherent novelty as expressed in the appended claims.

What I claim and desire to secure by Letters Patent is:

l. A turbulence rectifier comprising a tubular member having a cylindrical bore and end portions of restricted area in comparison with said bore, an obstruction arranged in the medial portion of the tubular member and of less diameter than the internal diameter of the medial portion of the member, said obstruction having substantially hemi-spherical opposite portions, and vanes arranged in the bore extending from one end portion to the other and forming a plurality of longitudinal passageways in the tubular member which are obstructed by said obstruction, the area between the medial portion of the obstruction and the bore being equal to either of the restricted end portions of the tubular member.

2. A turbulence rectifier comprising a tubular member having a cylindrical bore and end portions of restricted area in comparison with said bore, an obstruction of substantially ellipsoidal shape arranged in the medial portion of the tubular member and of less diameter than the internal diameter of the medial portion of said member, said obstruction having a cylindrical body and hemi-spherical end portions, and vanes arranged in the medial portion oi the tubular member extending from one end portion to the other and forming a plurality of longitudinal passageways in the tubular member which are obstructed by said obstruction, the area between the medial portion of the obstruction and the bore being equal to either of the restricted end portions of the tubular member.

3. A turbulence rectifier comprising a tubular member having a cylindrical bore and end portions of restricted. area in comparison with said bore, an obstruction of substantially ellipsoidal shape arranged in the medial portion of the tubular member and of less diameter than the internal diameter of the medial portion of said member, said obstruction having a cylindrical body and hemi-spherical end portions, and vanes arranged in the medial portion of the tubular member extending from one end portion to the other and forming a plurality of longitudinal passageways in the tubular member which are obstructed by said obstruction, the area between the medial portion of the obstruction and the bore being equal to either of the restricted end portions of the tubular member, said vanes intersecting one another between-said obstruction and the restricted end portions of the tubular member.

4. The combination with an upstanding oil and gas separator tank having an upper gas outlet and a lower liquid outlet, of means for conveying a mixture of oil and gas to and through the medial portion of the wall of said tank arranged at a point between said outlets, said means comprising a horizontally disposed tubular member arranged in close proximity to but exteriorly of said tank and having a cylindrical bore and end portions of restricted area in comparison with said bore, an obstruction arranged in the medial portion of the tubular member and having a circular outer surface of less diameter than the bore and equally spaced from the surface of the latter, said obstruction having substantially hemispherical opposite portions facing the restricted end portions of the tubular member, the area between the medial portion of the obstruction and the bore being equal to either of the restricted end portions of the tubular member, and vanes arranged in the bore, extending from one of said restricted end portions to the other and forming a plurality of equal passageways in the tubular member which are obstructed by said obstructions.
