Patent DE-3333134-A1 (DE)
Title: Device for measuring the attenuation of a surface acoustic wave, having an analog frequency output
Inventor: FORKE KLAUS DR ING
IPC: G01N29/02
Filed: 1983-09-14
Abstract: The field of application is the measurement of the change in transmission loss of delay lines with surface acoustic waves, which can be influenced by non-electric quantities such as moisture, gas concentration and others. It is the aim of the invention to create a measuring device which achieves high resolution and decisively reduces the complexity of the electronic section. According to the invention, the object is achieved by the fact that a three-transducer arrangement is applied to a piezo-electric substrate, the outer transducers of which are connected electrically in parallel as input transducers and the centre transducer of which is used as output transducer, the transit distances of the delay lines thus produced differing by at least one quarter of the wavelength of the SAW, the arrangement being located in the feedback branch of an amplifier and being connected together with it to form an oscillator. In one of the delay lines, means for damping the SAW in dependence on non-electric quantities are arranged. The device converts changes in the transmission loss of one of the delay lines into a change in the oscillator frequency.

Title: Method and device for producing ultra-short excimer laser pulses
Inventor: SZATMARI SANDOR DIPL PHYS DR
IPC: H01S3/20
Filed: 1983-09-16
Abstract: In the case of the present invention, a single, short laser radiation pulse is produced according to the teaching of the Main Patent P 3317065.7, by means of a laser medium which is common to two resonators of which the first has a relatively small optical length and low quality and the second has a relatively large optical length and high quality. The individual short laser radiation pulse is in this case extracted from the first resonator by means of a first relaxation process and, subsequently, the inversion in the common laser medium is held under the threshold value of the first resonator by means of a relaxation process which forms in the second resonator. The individual short laser radiation pulse produced in this manner is supplied as a pumping pulse to a laser which operates using distributed feedback (DFB), at such an intensity with respect to the laser threshold value of the DFB laser medium that the DFB laser emits at least one, separate, ultra-short radiation pulse.

Title: Process for drying goods cleaned by means of a liquid solvent
Inventor: ERBEL HORST
IPC: F26B25/00
Filed: 1983-11-02
Abstract: Hot air is supplied to the treatment chamber in which the goods are situated, is cooled after being sucked out of the treatment chamber, and then heated and supplied again to the treatment chamber. The air sucked out of the treatment chamber contains water and solvent vapours. The cooling of the air takes place in two stages, so that the air is as free as possible from solvent vapours at the end of the drying process. In the first stage it is cooled to about 0 DEG C, and a water/solvent mixture condenses, while in the second stage it is cooled to the solidification point of the solvent, which leads to a condensation or solidification of the solvent still present in the air.

Title: System for radiation cross-linking
Inventor: BAEUERLEIN RUDOLF DIPL PHYS
IPC: B29C35/08
Filed: 1984-04-02
Abstract: The system for radiation cross-linking a tubular body consisting of a cross-linkable material, such as, for example, a cable strand, by means of high-energy radiation has devices with deflection devices for passing the tubular body a number of times through the sector-shaped ray bundle of two radiation sources which are arranged offset with respect to one another by a predetermined angle. In order to make the all-round cross-linking of the tubular body even more homogeneous, the invention provides that each deflection device (6 to 8) has allocated to it at least one rotation device (10 to 12) by means of which the tubular body (2) is, between each of the individual passes through the two ray beams (ray fields 3 and 4), to be rotated about a predetermined angle (j) with respect to its circumferential direction. With each pass through the two ray beams (3, 4), each ray beam is to be at least largely aligned with a part-region of the circumference of the tubular body (2) which has not yet been irradiated. <IMAGE>
Patent DE-3418993-A1 (DE)
Title: Internal clamping set
Inventor: STUEWE HARTWIG
IPC: F16D1/093
Filed: 1984-05-22
Abstract: The known internal clamping sets for fixing hubs on shafts, which consist of an inner pressure ring and an outer pressure ring with tapered run-up faces and at least one clamping ring which can be inserted between the pressure rings and has pressure faces matched to the run-up faces, have the same taper angle as regards the pressure faces and the run-up faces. Since, in general, the hub to be clamped is stretched more than the shaft is compressed, it is frequently not possible for the full clamping force of the screws to be used for conversion into radial pressure because the clamping rings are stretched or compressed. According to the invention, the taper angles of the outer pressure ring 8 are larger than the taper angles of the inner pressure ring 4. The taper angles of the clamping rings 11, 12 are configured accordingly. In this way, it is possible to ensure that the clamping rings 11, 12 are neither stretched nor compressed during the clamping of the clamping set 3. The clamping force of the screws 15 can be used fully for conversion into radial pressure. <IMAGE>
