When the cutting edge is received in the notch, and the curved portion abuts the top face of a bolt, the plurality of horizontal lines is configured to measure a vertical distance from a center of the top face to the cutting edge, and the plurality of vertical lines is configured to measure a horizontal distance from the center of the top face to the cutting edge.

The measuring jig for the rotary machine is a measuring jig for a rotary machine including a casing that extending about an axis, a rotor that is disposed in the casing and extends in an axial direction about the axis, and a plurality of bearings that are disposed at intervals in the axial direction and supports the rotor in the casing. The measuring jig includes a plurality of casing fixing portions that are respectively attachable to and detachable from bearing holding portions to which the bearings are attached in the casing; a main member that extends in the axial direction so as to connect the plurality of casing fixing portions to each other; an arm that extends from the main member in an orthogonal direction orthogonal to the axial direction; and a reference surface that is disposed at a distance from a measurement target part of the casing.

A universal tram is provided for aligning machine tools. The universal tram includes a slide rail, featuring a rail along its length, to which a clamping coupler attaches. In turn, the clamping coupler attaches to the indicator holder. The indicator holder is configured to hold an indicator. The slide rail is configured for direct attachment to horizontal and vertical milling machines, for example. Optionally, the universal tram also includes a machine adapter and adapter plate. The machine adapter serves as a base block for positioning a measurement or tramming device on a machine tool to which the slide rail does not directly attach—a horizontal or vertical lathe, for example. The adapter plate allows for the height of the machine adapter to be adjusted by an amount corresponding to the thickness of the adapter plate. Further, a method of using the universal tram is also provided.

A wireline width measuring apparatus and associated method which may be used to measure static and dynamic fracture width in fractures used for energy storage, water injection, or hydrocarbon production. In one embodiment, the method comprises determining a depth of the formation fracture, determining the depth of the bottom of the wellbore, positioning a caliper tool string comprising a caliper apparatus at the bottom of the wellbore, wherein the caliper apparatus is positioned at a depth capable of measuring movement of a window cut into a casing of the wellbore at the depth of the formation fracture, inflating the fracture by injecting a fluid into the fracture, uninflating the fracture by producing the fluid from the fracture, and measuring movement of the window cut into the wellbore while the fracture is inflated and uninflated.

According to one embodiment, an inspection system inspects equipment including a first structural object and a second structural object. The first structural object extends in a first direction. The second structural object is provided around the first structural object. The second structural object has a first surface opposing the first structural object. A first protrusion is provided in the first surface. The first protrusion extends in the first direction. The system includes a robot and a controller. The robot includes an imager. The robot moves between the first structural object and the second structural object. The imager images the first protrusion. The controller detects, from a first image acquired by the imager, a first edge portion of the first protrusion in a circumferential direction around the first direction. The controller controls a movement of the robot by using the detected first edge portion.

A measuring device for measuring a width (W) between a first edge (4) and a second edge (5) of spaced apart opposed edges (4, 5) of a slot (16) in a product (1′), comprising: a measuring part (18), with a measuring detector and a display (28), and provided with a first tab (37) configured to enter into the slot (16), and a slide (29), defining a longitudinal axis (X), being arranged so as to be adjustable relative to the measuring part (18) along the longitudinal axis (X), and provided with a second tab (46) being configured to enter into the slot (16).

The slide (29) is adjusted so that a first surface (44) of the first tab (37) contacts the first edge (4) and a second surface (49) of the second tab (46) contacts the second edge (5).

A distance (d) between the first surface (44) and the second surface (49) corresponding to the width (W) is detected by the measuring detector, and the value of the width (W) is displayed by the display (28).

The first and second tabs (37, 46) are oriented downwardly relative to the measuring part (18), perpendicular or transverse to the longitudinal axis (X) of the slide (29).

A driving device includes a frame, a screw-nut system comprising a threaded rod and a first nut helicoidally connected to the threaded rod, the threaded rod being connected to the frame by a pivot connection that allows the threaded rod to rotate with respect to the frame about a longitudinal axis of the threaded rod, a first position sensor making it possible to detect a limit position of the first nut along the longitudinal axis, the first position sensor comprising a first part and a second part, the first position sensor being sensitive to a variation in a distance between the first part and the second part of the first position sensor along the axis, the first part being fixed to the first nut and the second part being connected to the threaded rod without passing via the pivot connection and in such a way that rotation of the threaded rod about the longitudinal axis leads to a variation in the distance between the first part and the second part of the first position sensor along the longitudinal axis.
