Publication number: 20190120013Abstract: A valve for limiting differential pressure applied to a downhole tool includes a housing and a movable piston/mandrel assembly therein. In a closed position, drilling mud or other fluid may be communicated through a central bore of the valve to the tool. When the differential pressure between the central bore and the wellbore exceeds a first predetermined value, the piston/mandrel assembly moves from a first position obstructing one or more relief ports to a second position not obstructing them, thereby providing a fluid path from the central bore of the valve to the wellbore bypassing the tool and relieving the differential pressure thereacross. When the differential pressure decreases to less than another preselected value, the piston/mandrel assembly returns to its original position again obstructing the relief ports. A trigger mechanism is provided to allow more precise control and separation of the preselected differential pressure values.Type: ApplicationFiled: October 16, 2018Publication date: April 25, 2019Inventors: Michael Glenn Gay, Ann Kamel Fitzgerald, Theodore Lee Cottrell, Phillip Graham Knight

Patent number: 10095112Abstract: The present disclosure relates to novel multiple trigger negative working photoresist compositions and processes. The processes involve removing acid-labile protecting groups from crosslinking functionalities in a first step and crosslinking the crosslinking functionality with an acid sensitive crosslinker in a second step. The incorporation of a multiple trigger pathway in the resist catalytic chain increases the chemical gradient in areas receiving a low dose of irradiation, effectively acting as a built in dose depend quencher-analog and thus enhancing chemical gradient and thus resolution, resolution blur and exposure latitude. The photoresist compositions and the methods are ideal for fine pattern processing using, for example, ultraviolet radiation, beyond extreme ultraviolet radiation, extreme ultraviolet radiation, X-rays and charged particle rays.Type: GrantFiled: February 24, 2017Date of Patent: October 9, 2018Assignee: IRRESISTIBLE MATERIALS LTDInventors: Alex Phillip Graham Robinson, Alexandra McClelland, Andreas Frommhold, Dongxu Yang, John Roth
