Abstract: Sealing adapters, pressure testing systems, pressure testing system kits, and associated methods. A sealing adapter comprises an adapter body and a mounting flange extending radially away from the adapter body. The adapter body includes a first end with a first sealing surface, a second end, and a fluid passageway. The mounting flange defines a plurality of stud receivers configured to receive mounting studs of a device under test (DUT). A pressure testing system may comprise a frame, a clamp structure with at least one sealing adapter, and a pressurizing assembly for delivering a pressurized fluid to the DUT. A method of pressure testing a DUT may comprise operatively coupling the DUT to the pressure testing system and delivering the pressurized fluid to the DUT.

Abstract: Adjustable feed mechanisms, machining assemblies including the same, and associated methods. An adjustable feed mechanism includes a plurality of cam segments and a cam lifter configured to pivot each cam segment about a corresponding cam pivot point. An adjustable feed mechanism additionally includes a cam follower and a feed output assembly. The cam follower moves along the cam segments sequentially and is pivotally coupled to the feed output assembly. The cam follower pivots through a cam activation angle when moving along a given cam segment to produce the feed output. A machining assembly includes a mount assembly, a rotary element, and an adjustable feed mechanism. A method of utilizing a machining assembly to machine a work piece includes engaging the work piece with a machining assembly, positioning the tool head with respect to the work surface of the work piece, and machining the work surface.

Abstract: Methods comprise machining each of an annular planar surface and a linear planar surface of a workpiece using a combination flange facer and milling machine. Methods comprise using a machine frame of a flange facer and a rotating ring of the flange facer to mount a milling machine to a workpiece, and machining the workpiece using the milling machine when it is coupled to the rotating ring of the flange facer. Portable machining kits comprise a flange facer and a milling machine that is configured to be operatively mounted to the rotating ring of the flange facer. Portable machine tools comprise a machine frame, a rotating ring, a bridge coupled to the rotating ring, a facing tool head assembly configured to be selectively coupled to and decoupled from the bridge, and a milling tool head assembly configured to be selectively coupled to and decoupled from the bridge.

Abstract: Pressure testing systems comprise a clamp assembly for clamping a device for testing with a test fluid, and a control assembly for controlling application of a clamp pressure to the device. The control assembly comprises a clamp control structure with an activated configuration and an inactivated configuration. In the activated configuration, the clamp control structure permits the clamp pressure to be applied to the device. In the inactivated configuration, the clamp control structure permits the clamp pressure to be released from the device. The control assembly also comprises a safety structure that is actuated by the test fluid between an interlocked configuration and a disengaged configuration. In the interlocked configuration, the safety structure physically prevents the clamp control structure from reconfiguring from the activated configuration to the inactivated configuration.

Abstract: Test flange assemblies comprise a flange body and a piston. The piston is configured to translate relative to the flange body and has an outer surface facing away from the flange body and an inner surface facing toward the flange body. The outer surface defines a circular seal channel for receiving a seal structure between the piston and a flange surface of a flanged component. The outer surface radially inward from the circular seal channel has a surface area that is less than a surface area of the inner surface. Methods of testing pressure containing structures comprise operatively positioning the test flange assembly, positioning a seal structure within the circular seal channel of the piston, coupling the flange body to a flanged component, and pressurizing a volume between the piston and the flange body so that the piston compresses the seal structure between the piston and the flanged component.

Abstract: Modular machine tools, modular machine-tool beds, and systems for assembling the same are disclosed. Some machine tools and beds may be configured selectively between a cantilever configuration and a gantry configuration. Some modular beds may be assembled selectively to have a desired longitudinal length. The modular nature of the machine tools and modular beds allows users to configure a machine tool in multiple configurations depending on a particular work piece needing to be worked.

Abstract: Various embodiments herein provide a remotely adjustable feed system for remotely controlling the movement of a tool head on a machining tool along an axis of motion by means of converting reciprocal linear motion, i.e., back and forth linear motion, into rotary motion. The rate of movement of the tool head along the axis of motion may be controlled by varying the distance of linear motion in each cycle of linear reciprocal motion and/or by varying the rate of linear reciprocal motion cycles per unit time. Alternatively, or in addition, the rate of movement of the tool head along the axis of motion may be controlled by varying the amount of rotary motion that results from a given amount of reciprocal linear motion. Additionally, in some embodiments, the movement of the tool head may be controlled by directly controlling the rotary motion that drives the tool head along the axis of motion.

Abstract: Machine tools and methods for machining turbine rotor assemblies are disclosed. Some machine tools include a drill arm that pushes off of a turbine stage that is adjacent to a turbine stage to be machined. Some machine tools include a clamping arm that secures the machine tool to a turbine stage to be machined and an adjacent turbine stage. Some methods include pushing-off of a turbine stage that is adjacent to a turbine stage to be machined. Some methods include securing a machine tool to a turbine stage that is adjacent to a turbine stage to be machined. Some methods include monitoring at least one of a current delivered to a first motor and a voltage applied to the first motor and controlling a second motor in response to the monitoring. Some methods include sequentially machining a turbine stage with cutting tools having increasing lengths and/or diameters.
