Abstract: A downhole tool includes a housing; a first piston arranged within the housing such that it can move axially under the action of fluid flowing through the tool; and an indexer configured to control axial movement of the first piston between a first, second and third axial position. The indexer is configured such that the first piston can be selectively moved into the third position in accordance with a variation of a flow of fluid through the tool. A second piston is movable between a closed position in which fluid flowing through the tool is restricted from communicating with an activation chamber and an open position in which fluid flowing through the tool is permitted to communicate with the activation chamber; wherein the second piston is configured to move between the closed position and the open position in response to the first piston moving to the third axial position.

Abstract: Methods and systems for integrating multiple portions of a container are provided. The method and system are specifically designed for integrating multiple shell portions with ear lobe-shaped tabs. The method comprises: providing a first set of retention structures to be associated with a plurality of inter-connecting features formed on an edge of a first shell part, wherein the first set of retention structures comprise at least a lead-in feature and a retention feature; providing a second set of retention structures to be associated with a plurality of inter-connecting features formed on an edge of a second shell part, wherein the second set of retention structures comprise at least a deflection feature and a retention feature; and engaging the two shell parts with aid of the retention structures.

Abstract: The present disclosure relates to novel multiple trigger monomer containing 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 utilize novel monomers and mixtures of novel monomers. 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.
