Abstract: A valve cover assembly for a pump. In an embodiment, the valve cover assembly comprises a first cylindrical member having a central axis and a first throughbore. In addition, the valve cover assembly comprises a second cylindrical member coaxially disposed within the first throughbore and rotatable relative to the first cylindrical member about the central axis between a first position and a second position. In the first position, the second cylindrical member is axially translatable relative to the first cylindrical member. In the second position, the second cylindrical member is axially fixed relative to the first cylindrical member.

Abstract: A system and a method are disclosed herein that relate to powering a pumping system within a downhole tool. The system may include a turbine having a shaft extending therefrom, in which the turbine is configured to convert energy from a fluid received therein into rotational energy for the shaft. The system may further include a pumping system coupled to the shaft of the turbine, in which the pumping system includes one or more driving devices coupled to one or more displacement units. The displacement units may have a cavity formed therein, in which the cavity is configured to receive a fluid therein. The driving devices may then be configured to drive the displacement units such that the fluid is received within the cavity of the displacement units.

Abstract: A method of generating compressive residual stresses through a thickness of a metal component comprising the steps: receiving a metal base component (10), which in use is subjected to applied pressure and applying by thermal deposition cladding (16) to one or more surfaces (14) of the base component. The cladding (16) comprises one or more layers of metal or metal alloy. The method also includes, subsequent to the cladding step, applying autofrettage to the clad component thereby generating compressive residual stresses through the one or more layers of metal or metal alloy (16) and at least part way through the base component.

Abstract: A method for forming peristaltic pump cassettes includes cutting tubing segments to different lengths based on the physical properties of the individual tubing segments. The size variations compensate for the physical parameters of the tube and improve accuracy in a peristaltic pump using the cassettes.

Abstract: An assembly system (68) for assembling a gas turbine engine including a support beam (70) defining a horizontal plane for assembly of engine components along a horizontal axis substantially parallel with the support beam (70). A forward arm (102) is supported on the support beam (70) for supporting a forward portion of an engine component. An aft arm (90) is supported on the support beam (70) for supporting an aft portion of the engine component. An aft mounting ring (100) is attachable to an aft end of an engine assembly. A forward mounting ring (106) is attachable to a forward end of the engine assembly. A drive (92) is mounted to the aft arm (90) engageable to the aft mounting ring (100) for rotating the engine assembly about the horizontal axis. A roller (112) is supported on the forward arm (102) and engageable to the forward mounting ring (106) to support the first end of the engine assembly during rotation about the horizontal axis.

Abstract: In a positioning apparatus (40), a fixed scroll (34) is positioned with respect to an assembly body (11) in which a compressor motor (25) has been incorporated. In positioning the fixed scroll (34), electric power is supplied to the compressor motor (25) from an inverter (81) to rotate a crank shaft (20) by the compressor motor (25), thereby shifting a movable scroll (31). In the positioning apparatus (40), the shift of the movable scroll (31) leads to calculation of an appropriate position of the fixed scroll (34). A striking unit (70) applies impact force to the fixed scroll (34) to stir the fixed scroll (34) to the appropriate position.
