  • Patent number: 8967178
    Abstract: A valve assembly configured to close off the flow of fluid within a fluid injection assembly includes a fluid column having a first open end and a second open end. A fluid flow path is defined between the first and second open ends of the fluid column, and a saturation valve portion is disposed within the fluid flow path. The saturation valve portion is a first configuration when no fluid is flowing through the fluid flow path, and the saturation valve portion transitions to a second configuration when fluid is flowing through the fluid flow path.

  • Publication number: 20110294350
    Abstract: A connector or similar apparatus for connecting or terminating at least one cable or cable section is provided. The connector includes at least one stepped cavity for receiving a cooperatingly sized and configured stepped conductor end of the cable or cable section. The stepped cavity includes two or more adjoining cavity sections of decreasing diameter. After insertion of the stepped conductor end of the cable or cable section into the stepped cavity, the cable or cable section may be affixed to the connector via crimping or other suitable coupling techniques. Prior to insertion, the stepped conductor end is cleaned so as to remove oxidation, dirt and debris, and/or strand fill, etc.
