Abstract: Method and apparatus for recovering glass from old glass by continuously feeding the old glass onto an open, continuously running conveyor system by segregating nonglass impurities and by mechanically crushing old glass in a breaking apparatus. To facilitate visual inspection and concentrating the size range of the shards, a sorting of the old glass into two fractions of different piece sizes is performed in a separating apparatus prior to the manual sorting and before crushing. Exclusively the old glass of the at least one coarser fraction ("coarse glass") is fed, after the segregation of at least a portion of the nonglass impurities, to the breaking apparatus. Then the old glass of this fraction, crushed to the desired shard size, is freed of remaining impurities and finally fed to a place of storage for good glass. After the segregation of at least a portion of the nonglass impurities, the old glass of the at least one finer fraction ("fine glass"), is fed without additional breaking, to a mechanical separating apparatus for the segregating of remaining metallic impurities and finally to a place of storage for good glass.

Abstract: The recording current necessary for recording a video signal is always to be optimally selected and adjusted with respect to the replay sensitivity, having regard to an audio signal already recorded on the same tracks and having regard to tolerances of the recording medium, of the heads and of the head amplifiers, by means of the novel method. For this purpose, the recording current is changed in steps during the recording of the video signal. After each change in the recording current for the video signal, a direct-voltage value is determined from the replay envelope curve of the audio signal as a measure of the replay amplitude of the audio signal. As soon as the direct-voltage value obtained from the replay envelope curve of the audio signal reaches a predetermined minimum value, the changing of the recording current for the recording of the video signal is ended and the last value of the recording current is stored for the following recording process. Recording systems in which video and audio signals are stored in tape layers of different depth. <IMAGE>

Abstract: An assembly for preventing reverse rotary rotation of shaft (4) comprises a disc (10) including openings (16) having circumferentially spaced-apart ends formed in the disc and pins (32) mounted to a stationary support (8) opposite the openings in the disc and biased towards the disc. The leading end of the opening has an abutment surface (28) perpendicular to the plane of rotation of the disc. The trailing end (30) of the opening is ramped. The outer end (38) of each pin is sized to fit within the openings and has an abutment surface (40) oriented perpendicular to the plane of rotation of the disc and configured for complementary mating engagement with the abutment surface defining the forward edge of the opening. The outer end of the pin is an angled or ramped surface (42). Forward rotation of the disc causes the two ramped surfaces (30, 42) to engage, biasing the pin away from the disc. The pin then slides along the surface of the disc until another opening is encountered at which time the process is repeated. Attempted reverse rotary rotation will cause the two abutment surfaces (28, 40) to engage which prevents any further reverse rotation of the disc.

Abstract: Optical transmitting circuits with semiconductor transmission elements, e.g. laser diodes, and optical receiving circuits with photodiodes are normally used for optical data transmission via optical fibres. According to the invention, an optical transmitting circuit with a semiconductor transmission element is also used in a second operating mode for receiving optical signals. In this process, the control of the semiconductor transmission element (L) effected by the driver (LT) is de-activated and the semiconductor transmission element (L) is operated as an optical-electrical transducer. An advantageous use of the invention involves two-way optical transmission via a single optical fibre, wherein transmission and reception are carried out alternately in both directions. Due to the dual use of the semiconductor transmission element, there is no need for the special receiving diode normally used for reception purposes nor for the further optical components when used in a two-way system for route and wavelength segregation. <IMAGE>

Abstract: In order to test aspheric surfaces or aspheric wave fronts, the collimator (8) - the generator which generates the test wave - of the interferometer is displaced relative to the test sample (12) and interferograms are electronically recorded in various positions of the collimator by means of an image sensor (5) and stored as optical path differences between the test beam and the reference beam for the individual image points of each interferogram. The relative position between the collimator (8) and the test sample (12) is also measured with great accuracy. 
<??>Subsequently, the interferometrically measured optical path differences are compared with theoretical optical path differences which are computed for the various positions of the collimator or determined by calibration, and the aspheric shape of the wave front of the test sample as a whole is computed therefrom. In this case, the measured values which are obtained for the various partial regions of the test sample and in which the test wave impinges substantially normally on the surface of the test sample are integrated over the entire surface of the test sample.
