Abstract: A downhole tool for transmitting rotation to a casing string includes a tool body having a bore extending from a first end to a second end. The downhole tool also includes a cam positioned within the tool body, the cam being axially translatable along an axis of the bore. The downhole tool further includes a recess, formed in an outer diameter of the cam. The downhole tool includes a locking mechanism, positioned at least partially within the tool body. The locking mechanism includes a tool key. The locking mechanism also includes a biasing member, the biasing member driving the tool key toward the retracted position.

Abstract: A tool assembly, a method and a system to be used in a downhole environment for downhole operations such as runs and retrieval of features are disclosed. A tool assembly include an outer tool profile, an inner matching profile, and a first interfacing surface. The inner matching profile is to be associated with an interfacing profile of a tool body and is to allow axial sliding for a first lock of the tool assembly to the tool body. A second lock is provided at a first shoulder-surface interface between the first interfacing surface and the tool body. The tool assembly is to be changeably associated with the tool body for use in the downhole operations.

Abstract: A test device (80) for testing for the presence of a substance in a sample held on a sample carrier (30) includes a holder (82) for holding a sample carrier (30) which includes one or more chambers (50,52). The test device (80) also includes an actuator for compressing or depressurizing the chamber(s) (50,52). The actuator is configured to prevent reinflation of the chamber(s) (50,52) after compression or depressurization.

Abstract: This disclosure relates to amides, aryl sulphonamides, aryl ureas, and ?,?-diketones derivatives useful as carboxylesterase esterase inhibitors. The disclosure is also directed to the use of these compounds as selective human intestinal carboxylesterase inhibitors and insect carboxylesterase inhibitors. The disclosure is also directed to pharmaceutical compositions and pesticide formulations containing these compounds, and to methods for treating or ameliorating the toxic effects following administration of drugs such as cancer therapy drugs, treating or ameliorating the effects of a drug overdose, and to the use of the compounds for increasing the effectiveness of insecticides and pesticides.
