Applicant has disclosed a chamfer gage with interchangeable anvil assemblies which can measure the diameter of chamfered holes and the chamfer angle (up to 135°). In the preferred embodiment, the chamfer gage comprises: an indicator housing; a compression fitting, attached to the housing, for securing an indicator spindle for movement inside the housing; and an interchangeable anvil assembly, having an anvil body with a depressible anvil or plunger inside, which can be detachably connected to the indicator housing by a threaded thumb ring rotatably mounted on the housing. Another interchangeable anvil assembly can be swapped within thirty seconds to measure the chamfer of a different hole size.

A plug gauge includes a housing defining an internal volume and a longitudinal axis AH. The housing includes an opening into the internal volume. The plug gauge also includes a contact element at least partially received in the opening. The plug gauge further includes a plunger at least partially received in the internal volume. The plunger is biased into engagement with the contact element to urge the contact element radially outward from the housing through the opening. The plug gauge additionally includes a sealing member between the contact element and the housing.

A gauge apparatus includes a body member, one or more gauge arms biased outwardly from the body member for engagement with a wall of the elongated space, and one or more deformable regions. The gauge apparatus is configured so that a variation in an outward extension of each gauge arm from the body member induces a change in strain in a corresponding one of the one or more deformable regions. A gauge system includes the gauge apparatus and an optical fiber attached to the gauge apparatus so that a strain in each deformable region of the gauge apparatus is transferred to a corresponding sensor portion of the optical fiber. The gauge system may be used for making real-time measurements of a geometry of an elongated space such as a wellbore of an oil and gas well.

A spacer tool for assembling a glass panel on a frame is provided. The spacer tool includes a body defining a central axis and a width along the central axis. The spacer tool includes a bore disposed within the body and axially aligned along the central axis. The bore is adapted to receive an alignment pin disposed on the frame. The spacer tool also includes a plurality of lands disposed on the body. Each of the plurality of lands is disposed substantially parallel to and spaced apart from the central axis, each of the plurality of lands is adapted to selectively contact an edge of the glass panel. Each of the plurality of lands is disposed at a distance relative to the central axis different from one another.

A downhole borehole imaging tool and methods for determining a borehole size includes a magnetoresistive system and a hub moveably coupled to a fixed tool string. The hub includes a magnet. The magnetoresistive system includes magnetoresistive sensors disposed within the fixed tool string and segregated from the magnet. During operation, a routine scan of all sensors measures, for example, the output voltage V, angle θ of magnetic field, and temperature. Measurements from each sensor may then be characterized to account for temperature and input voltages variation of the sensors. The most accurate measurement can be used to derive the position of the hub 44 using the previous baseline parameters stored in the tool.

A right angle touch gauge of the present application includes a fixing block, a floating column, a spring, a measuring column, a measuring sleeve and the like. In use, round head of top end of the floating column is in contact with bottom surface of work piece. The floating column is compressed downward when it touches high surface of the bottom surface of the work piece, the measuring column is compressed to right by matching lower cone of the floating column and left cone of the measuring column, and it may be found whether height difference between high surface and low surface of the bottom surface of the work piece is qualified by observing whether end edge of the right cylinder of the measuring column is placed between steps of right end surface of the measuring sleeve.
