Abstract: Apparatus for sensing test values at test samples which uses an elastically supported mechanical sensor (3) moving relative to test samples (4) and at least one test value transmitter (11) with counter (9) detecting the relative motion between the sensor (3) and the test samples. At the instant of impact between sensor (3) and the test samples (4), a signal is generated which is used to store the test value present at the test value transmitter (11) at the instant of impact between the sensor (3) and the test samples (4) into a memory (13a,13b). The sensor consists of one part (2') which is fixed to the housing and other part (2") which is movable with respect to the fixed one. An oscillation or acceleration pickup (10) is mounted externally to the moving part (3) and generates the signal required to store the test value.A circuit (14) is provided to the oscillation or acceleration pickup (10) to distinguish between actual sensing signals and spurious ones.

Abstract: Instrumentation for sensing the test values at test samples, using a mechanical sensor moving relative to the test sample and consisting of a housing fixed part and of a movable, articulating multi ball and socket part connected to the housing fixed part and at least one test value transmitter. A trigger signal is generated in the instrumentation at the instant of impact between sensor and test sample and is stored to record the test value present at the time of impact at the test value transmitter.At least one force or acceleration pickup (12,23,24,30) is provided which is mounted on the housing fixed part (2) of the sensor (5) and delivers the trigger signal.

Abstract: Method and apparatus for automatically evaluating an indentation produced in a material according to the Vickers hardness testing method. A diaphragm apertured in two coordinate directions is guided over an image of the indentation, while a photoelectric receiver system produces an electrical signal representing the luminous flux passing through the diaphragm. The electrical signal is differentiated, and changes in the differentiated signal exceeding predetermined thresholds are used to indicate detection of edges of the indentation. The respective positions of the diaphragm when the indentation edges are detected, and a known dimension of the diaphragm, are used to calculate the length of a diagonal of the indentation.

Abstract: Disclosed is a linear micrometer which comprises a cylindrically shaped housing, a tube-shaped sleeve displaceably mounted along the longitudinal axis of the housing and extending from one end of the housing, a measurement scale fixedly mounted along the longitudinal axis of the housing and slidingly supported inside the spindle sleeve, and a measurement readout means couple to the spindle sleeve for reading and displaying the relative position of the spindle sleeve to the scale. A rapid adjusting means and fine adjusting means are also provided.

Abstract: A process of and an apparatus for the automatic measuring of a workpiece. The workpiece is carried on a coordinate table which is mounted for movement relative to a scanning head in two mutually orthogonal directions. A control device moves the workpiece relative to the scanning head at a constant rate in one direction and at a rate in the other direction so as to maintain a constant pressure of the scanner head on said workpiece. The rates of movement in both directions are periodically compared and when equality is reached reversal occurs wherein control of the constant rate is switched to the scanning head and control from the scanning head is switched to a constant rate. This reversal permits uninterrupted measuring in an automatic mode.

Abstract: The angular position of a workpiece relative to a reference direction is determined by means of an optical correlator including an imaging system and an optical grating. The workpiece is imaged on the grating and means are provided for effecting a relative lateral displacement between the image and the grating. Photoelectric receiver means are positioned behind the grating in the direction of light flux for generating electrical signals of which the value depends on the angular position of the workpiece relative to the grating. The correlator is rotatable about its optical axis and the electrical signals are of an extreme value when the workpiece and the grooves of the grating are in alignment. Detecting means are connected to the receiver means for sensing this extreme value.

Abstract: A sensor for calipering workpieces having one spring parallelogram for Apr. motion in each coordinate axis wherein additional spring means vary the spring constant in at least one of the spring parallelograms. The spring means include two coil springs acting in opposition to one another having between the opposed ends intermediate spring bolts, ball stops between the heads of the bolts and a bending rod with a ball at the end thereof acting on the heads of the bolts to compress the coil springs while being held without play by the ball stops.
