A method for relieving residual stresses in a part includes increasing the rotation speed, which includes measuring, at a first given instant, values representative of the rotation speed and the radial enlargement; measuring, at a second given instant after the first instant, values representative of the rotation speed and the radial enlargement; determining a leading coefficient of a first affine function from the preceding values; determining a target radial enlargement value as a function of a value representative of the rotation speed, in the form of a second affine function, the origin of which is the value of a desired final residual enlargement and the leading coefficient of which is the leading coefficient of the first affine function; stopping the increase in rotation speed of the part from the moment that the actual enlargement of the rotating part corresponds to the target relative radial enlargement value that has been determined.

A stalk-diameter sensing system comprises a first stalk feeler, a second stalk feeler, a first sensor, a second sensor, a first damper, and a second damper. The first and second stalk feelers are deflectably mounted on opposite sides of a stalk-receiving gap that receives a stalk. The first and second stalk feelers are yieldably biased into the stalk-receiving gap for deflection upon contact with an outer surface of the stalk. The first sensor is coupled to the first stalk feeler to sense deflection of the first stalk feeler and generate a first signal. The second sensor is coupled to the second stalk feeler to sense deflection of the second stalk feeler and generate a second signal. The first damper is positioned to dampen deflection of the first stalk feeler. The second damper is positioned to dampen deflection of the second stalk feeler.

An arrangement for automatically contactlessly detecting elongate objects (W), such as cables, wires or profiles, has a quasi-coaxially arranged group of a first optical measuring system (D) for determining the external diameter and a second optical measuring system (C) for determining the color using a different measurement principle. The functional and local separation of the two measuring systems (C, D) is achieved by using different wavelength ranges and by a long-pass filter (C3). A third, virtual measuring system (P) may be provided for the purpose of determining the cable location and is used to weight measured values of the color measurement and measured values of an optional eddy current sensor. The optical measuring systems (D, C, P) for determining the diameter, the color and the position have a common optical disc-shaped measuring volume (DCPv) which is preferably arranged centrally in the guide device (4a, 4b) for the elongate object (W).

An operator controlled wire rope maintenance apparatus for remotely discerning and locating wire rope wear problems.

A system and method for characterizing surfaces includes using a measuring device to take size measurements of a manufactured product. The raw measurement data is transformed from a time-based domain to a frequency-based domain using a mathematical algorithm. The transformed size measurement data is then compared to predetermined limits within comparable frequency bands to characterize the surface of the manufactured product.

An assembly for automatically detecting contactlessly elongate objects (W). The assembly comprises an inductive measuring system (E) and a first optical measuring system (D) for the object (W) within a housing (2). The inductive measuring system (E) is an eddy current sensor for determining an electromagnetic characteristic of the object (W) and has half coils (E1a, E1b) which wind around the object (W) and forms an inductive cylindrical measurement volume (Ev). The half coils (E1a, E1b), together with a capacitor (E2), form a parallel oscillating circuit (E6), which is connected to an electronic evaluating circuit (E5). The first optical measuring system (D) determines the outside diameter (Wdo) of the object (W) and an optical disk-shaped measurement volume (DCPv) is formed between the two half coils (E1a, E1b). Optionally, the assembly, by a second optical measuring system (C), determines the color and the position by a third virtual measuring system (P).
