Abstract: A valve housing has a first flapper moveable from an open position in the housing in which two-way flow is allowed to a closed position in which only one-way flow is permitted. A first collet sleeve is moveable from a first position to a second position in the valve housing. The first collet sleeve in the first position retains the flapper valve in the open position. The collet sleeve is moveable from a first position to a second position which allows the flapper to move to a closed position.

Abstract: Provided is an inner sleeve, a downhole tool, and a method for cementing. The inner sleeve, in at least one aspect, includes a tubular having an inside tubular surface and an outside tubular surface. The inner sleeve, according to this aspect, further includes a collet including two or more collet fingers coupled to one end of the tubular, the collet having an inside collet surface and an outside collet surface, and further wherein the inside collet surface flares outward from the inside tubular surface by an angle (?0) when the collet is in its natural state.

Abstract: A method of anchoring a housing to an inner diameter of a tubing string can include: installing an anchoring assembly at an end of the tubing string, the anchoring assembly comprising: a body; the housing; an installation sleeve; a rotating sleeve in threaded connection with the housing and the installation sleeve; and a plurality of anchoring buttons located within a plurality of cutouts on the housing; causing movement of the body along a longitudinal axis of the tubing string towards the end of the tubing string that causes the plurality of anchoring buttons to circumvolve around a pin and an edge of the anchoring buttons lockingly engages with the ID of the tubing string after circumvolving; releasing both of the installation sleeve and the rotating sleeve from engagement with the tubing string, the body, and the housing; and removing the installation sleeve and the rotating sleeve from the anchoring assembly.

Abstract: Mounting apparatuses for turbine airfoils of turbine systems are disclosed. The mounting apparatuses may include a body portion configured to be at least partially positioned between a first airfoil and a second airfoil of the turbine system, and an adjustable, first retention component formed on a first side of the body portion. The adjustable, first retention component may be configured to contact a portion of a suction side of the first airfoil of the turbine system. The mounting apparatuses may also include a second retention component formed on a second side of the body portion, opposite the first side. The second retention component may be configured to contact a portion of a pressure side of the second airfoil of the turbine system.
