Abstract: An inductive proximity switch includes a coil that is supplied with periodic transmitting current pulses. Signals which correspond to voltages induced in the coil after the end of a transmitting current pulse by the decaying current which previously flows in the detected body due to the voltage induced therein by the transmitting current pulse are then processed. The coil is supplied with transmitting current pulses whose direction alternates periodically. The current flow pattern is such that in the first half of a period of the current supplied to the coil, the transmitting current delivered to the coil flows in a first direction and substantially only during a first interval which is shorter than one half of the period of the transmitted pulses. The transmitted current subsequently decays during a time interval and is negligibly small during the remaining time of the first half of the period. In the second half of the period, the transmitting current delivered to the coil flows in a direction opposite to the first one and substantially only during a second interval which is shorter than one half of the period of the transmitted pulses. The transmitted current subsequently decays during a time interval, and is negligibly small during the remaining time of the second half of the period.

Abstract: The method for the differential measurement of an angle of incidence of a luminous beam uses a polarized light beam which is passed twice through a birefringent plate followed by a polarizing analyzer in order to obtain a succession of interference fringes. The orientation or the mutual spacing between the crests of said fringes, which are a direct function of the measured angle (.gamma.), are analyzed by means of a suitable detector and of an electronic analyzing circuit. The measuring device comprises a single polarizing analyzer, a birefringent plate which is followed by a mirror in order to reflect the light beam through said birefringent plate a second time, and means for detecting the variations of the luminous intensity including an electronic analyzing circuit. The use of a double passage through a birefringent plate ajusts the optical elements in one plane (V) in order to optimize the efficiency and the sensitivity while measuring in the other plane (H), thus obtaining a device which is simple and at the same time very sensitive to angular displacements, for example for the measurement of vibrations.

Abstract: The optical device comprises an emitter optic for projecting a light beam onto an object, and a receptor optic for projecting the reflected light onto a detector. The emitter optic and the receptor optic each comprise a dome disposed in such a manner that the light beam passes through the dome in a plane which is parallel to the plane surface of the dome. This allows a very compact design which is particularly suitable for reflection detectors of small dimensions.

Abstract: In an oscillator comprising a resonant circuit (L, C, R.sub.CU) and an amplifier circuit (V, R.sub.1, R.sub.2, R.sub.3) connected as a negative resistance (R.sub.n), a direct current source (I.sub.1) is connected in series with the resonant circuit (L, C, R.sub.CU). In this way, a signal (U.sub.CU) is provided being a measure for the resistance of the oscillator circuit coil (L). By using this signal (U.sub.CU), a control circuit (V.sub.1, M; V.sub.2, V.sub.3, M) controls the negative resistance (R.sub.n) inversely proportional to the resistance (R.sub.CU) of the oscillator circuit coil (L). This affords a simple stabilization of the temperature behavior of the oscillator circuit (L, C, R.sub.CU) and allows the low price manufacture of inductive proximity switches having a great switching distance which function safely in a broad temperature range.
