    摘要: A method of checking the presence or absence of an X-ray sheet film in a cassette inserted into an automatic film unloading or loading apparatus, utilizes a proximity sensor arranged in the apparatus to sense position changes of a sheet film supporting foil which is arranged for a limited movement in the cassette. The proximity sensor is connected to an electronic control device which controls the operational sequence of the unloading and loading apparatus. When the gripping member preferably in the form of a suction cup seizes a sheet film on the supporting means in the cassette, the supporting means remain in its rest position after the sheet film is removed. However, if no film is present on the supporting means, the suction cup seizes the supporting means and displaces the same from its rest position. This change is sensed by the sensor and a signal is delivered to the electronic control circuit which modifies the operational sequence accordingly.

    摘要: A reaction product is formed from a tertiary amine and an acid mixture of (i) boric acid and (ii) a carboxylic acid. The reaction components are generally used in quantities such that the molar ratio of tertiary amine to acid mixture is from 1:0.1 to 1:10. The molar ratio of the boric acid to the carboxylic acid in the acid mixture is generally from 1:100 to 1:0.01. These reaction products are particularly useful as catalysts in the production of isocyanate addition products.

    摘要: An X-ray film cassette has on its top a triangular bar code field readable by a bar code reader of an automatic film sheet charging and discharging apparatus. The bar code field is in the form of an isosceles right triangle whose hypothenuse faces a reference corner and whose legs extend parallel to edges of the cassettes. The bars of the code extend parallel to the hypothenuse. An optical axis of the bar code reader, when the cassette is in its end position in the apparatus, intersects a vertex area formed by the legs of the triangle. This arrangement guarantees that its bar codes on cassettes of small format, even if misaligned in the feeding direction, are reliably read by the reader.

    摘要: The flow of direct current and/or ringing alternating current in a telephone line subscriber loop is detected by means of current flow detectors. The output signals produced by the current flow detectors are applied to an evaluation circuit, the zero-crossings of the ringing alternating current being used to determine whether a ringing alternating current has been superimposed on the loop direct current.In order to increase the reliability of the evaluation and to detect noise voltages coupled into the subscriber-loop, the durations of positive and negative half-waves of the loop current are measured and the evaluation is effected by comparing the sum and the ratios of the measured values relative to a presettable threshold.

    摘要: Method for producing workpieces having polygonal outer and/or inner contours, preferably by machining, wherein the workpiece to be machined rotates at a constant speed about a stationary axis, while the tool is guided on a closed, curved path, with the rate of rotation of the workpiece and the speed at which the tool revolves on its curved path being dependent upon one another and wherein further the tool engages at the workpiece during the entire revolution. The traveling speed of the tool during one revolution is varied according to a law of motion which is defined by the stationary rotation of the workpiece, the path of movement of the tool and the desired polygonal contour. The tool is guided, preferably translatorily, on a circularly cylindrical path.
