  • Patent number: 11990626
    Abstract: Catalyst comprising an Ir layer having an outer layer with a layer comprising Pt directly thereon, wherein the Ir layer has an average thickness in a range from 0.04 to 30 nanometers, wherein the layer comprising Pt has an average thickness in a range from 0.04 to 50 nanometers, and wherein the Pt and Ir are present in an atomic ratio in a range from 0.01:1 to 10:1. Catalysts described herein are useful, for example, in fuel cell membrane electrode assemblies.

  • Patent number: 10683714
    Abstract: A mud screen manifold in which a saver sub chamber, a screen chamber and a mud inlet chamber are formed in a body. A hollow saver sub is provided, suitable for insertion into the saver sub chamber after connection to a screen cage. When a shaped flange on the saver sub is received into a correspondingly shaped recess formed in the saver sub chamber, a mud flow inlet is in fluid flow communication with a cutout in the saver sub via the mud inlet chamber, and the saver sub is in fluid flow communication with the screen chamber via fluid flow through the screen cage. Contact seals prevent fluid flow from leaking around the screen cage. The mud inlet chamber, the saver sub and the saver sub cutout preferably cooperate to form a smooth-walled passageway for fluid flow communication between the mud inlet chamber and the screen cage.

  • Publication number: 20140090667
    Abstract: A method and apparatus for cleaning, treating and inspecting tubular goods including, without limitation, continuous tubing. Tubing is fed through a box-like housing having an inner chamber. As the tubing proceeds through the housing, the exterior surface of the tubing passes through an initial squeegee wiper to remove moisture, debris and environmental contaminants. Thereafter, the external surface of the pipe is washed using a high pressure liquid spray followed by another wiper squeegee and gas (typically air) dry station. After the pipe is sufficiently dry, liquid rust inhibitor and/or other treating fluid can be applied to the outer surface of the pipe before the pipe exits the housing.
