Abstract: A carburetor attachment is designed for replacing a main jet(s) found in the float chamber of a carburetor. The attachment comprises an elongated tubular member with a bore running therethrough and presenting an opening at the lower end thereof. Threads at the lower end of the tubular member fasten the attachment to the threaded socket presented by removal of the normal main jet. In place, the upper end of the attachment extends above the normal level of the fuel found in the float chamber and has a port thereat providing communication between the internal bore and the surrounding ambient air. An inclined port adjacent the lower end of the tubular member provides a conduit between the surrounding fuel and internal bore. Upon actuation of the carburetor the resulting suction presented within the bore draws the surrounding ambient air and fuel through the respective ports for admixture therein.

Abstract: Disclosed is a swivel assembly with multiple fluid bearings. The embodiment shown is a rotatable liner swivel assembly to be used, in conjunction with a liner hanger, cam dog assembly, and setting tool, for placing and cementing a liner in a well. Fluid-filled annular bearing chambers in the swivel assembly support the load of the liner pipe string, and permit the rotation of the liner pipe string with respect to the liner hanger during the cementing process. The bearing chambers are interconnected to equalize the fluid pressure and distribute the load uniformly over the bearing chambers.
