Patent DE-3823965-A1 (DE)
Title: Optical waveguide (LWL) line for conveying (mining) equipment
Inventor: DINZEN HELMUT DIPL ING
IPC: G02B6/44
Filed: 1988-07-15
Abstract: Optical waveguide lines are known which have the following construction: in the core, a plurality of optical waveguides (2) is stranded with or around a strand of reinforcing fibres (1) of an aramid or glass, the interfaces are filled with a water-proofing filler (3), and around it there is a sheath (4) of an elastomer-polymer. An optical waveguide line of this kind shall be designed for use in strip-mining conveying equipment. The solution essentially consists in that a) two further sheaths (7 and 9) of crosslinked elastomers are applied around the line sheath (4) and a tension and torsion relief lining (8) is embedded in the outer sheath (9), b) at least one layer (5) of yarn of high tensile strength is arranged between the line sheath and the intermediate sheath (4 and 7, respectively), leaving play for the optical waveguide line, and c) a heat-insulating wrapping (6) is applied over it. In short: the optical waveguide line is arranged with its sheath (4) so as to float and in a heat-insulating manner in the two outer sheaths (7 and 9). An optical waveguide line of this kind is preferably used for conveying equipment in strip mining, such as spreaders and diggers (excavators). <IMAGE>

Title: Process for producing complicated components of silicon-infiltrated silicon carbide
Inventor: YARAHMADI MOHAMED DR ING
IPC: C04B37/00
Filed: 1988-09-19
Abstract: To be able to omit the expensive subsequent processing (final machining) of individual SiSiC parts which are to be accurately fitted together to give a larger component, e.g. a tube heat exchanger, it is proposed to assemble the individual parts in the "green" state, to fill the gaps between them with a slurry of silicon carbide and only then to impregnate the assembled component (1-3) with silicon and to fire it. The component thus produced can, if required, be connected without difficulty to further individual parts (4) of finished SiSiC. <IMAGE>

Patent DE-3841611-A1 (DE)
Inventor: DIETZ HERMANN DR DIPL CHEM
IPC: G01N27/416
Filed: 1988-12-10
Abstract: The description relates to a sensor element for boundary flow sensors to determine the lambda value of gas mixtures, especially the exhaust gases from internal combustion engines, with outer and inner pump electrodes arranged on a ceramic support, where the inner pump electrode is accessible to the measuring gas fed in via a diffusion layer acting as a diffusion barrier, a gastight covering layer over the diffusion layer and conductive tracks for the pump electrodes, where the diffusion layer can be equalised to calibrate the sensor element. The equalising capacity is advantageously achieved in that the side of the diffusion layer facing the measuring gas inlet takes the form of a crenellated equalising region from which parts may be separated mechanically or by laser-cutting. The invention facilitates the calibration of sensor elements.

Patent DE-3842158-A1 (DE)
Title: Elastomer clamping assembly with a valve piston
Inventor: MENKHOFF KARLHEINZ
IPC: F16F9/30
Filed: 1988-12-15
Abstract: The elastomer clamping assembly with a valve piston has the advantage over the known double-chamber system that the valve is installed directly in the piston and therefore does not require the double chamber. Due to the valve piston, three forces counteract the entry of the piston rod into the cylinder space.     1. The prestressing force of the compressible elastomer.   2. The prestressed spring. 3. The dynamic pressure on the surface of the valve piston, which is dependent on the speed of the retracting piston rod.   On completion of the working stroke of the piston rod, the compressible elastomer expands and extends the piston rod again.

Patent DE-3904287-A1 (DE)
Title: Arrangement for cutting with laser beams
Inventor: SCHIRMER KURT DR
IPC: B23K26/402
Filed: 1989-02-14
Abstract: During cutting with a laser beam, material changes occur at its point of impingement which affect the repeated use and efficiency of the laser beam. According to the invention, provision is made to transmit a thermal laser beam and a photodisruptive laser beam via a common optical axis and to combine them to make an output beam in which a photodisruptive laser beam and a thermal laser beam occur alternately. The different laser beams produce different effects at the point of impingement, as a result of which a high energy output is obtained at the cutting point. Cuts are made in materials containing liquid.

Title: Trickle (drip, cascading) panel made from plastic trickle walls stacked one on another
Inventor: HEWING BERND
IPC: F28F21/06
Filed: 1989-02-24
Abstract: The invention relates to a trickle panel for cooling towers and the like, consisting of at least two trickle walls which are fastened one on another and are manufactured from stiff thermoplastic synthetic foil which is equipped with stand-up fastening elements distributed in the manner of a matrix (grid). In the case of the trickle walls, which are situated one above another, fastening elements are constructed in the form of small hollow columns or hollow cones or the like, over which the corresponding fastening elements of the adjacent trickle wall slip in the manner of a thimble or push button and are aligned in a straight line. In order by comparison with the prior art to improve welding of the individual trickle walls to one another with the aid of welding devices, and to avoid defective points and to simplify the configuration of trickle walls, the invention proposes that the trickle walls are configured as corrugated surfaces having crest and trough regions extending parallel to one another. The said compatible fastening elements are arranged both in the crest regions and in the trough regions. The invention also proposes that the two trickle walls respectively fastened to one another are arranged relative to one another in such a way that the alignments of the crest and trough regions form an angle relative to one another.

Title: Hot flue for treating continuous flexible strip - compensates for friction of roller support bearings by sprocket shape on non-bearing rollers, driven by endless chain
Inventor: PAULUS HELMUT
IPC: F26B13/08
Filed: 1989-09-06
Abstract: A continuous strip of flat flexible material is subjected to heat treatment by passing it in zig-zag fashion around rollers, arranged inside a hot flue (3). The rollers are arranged in two  parallel groups (5,8) with the end roller (9) being driven. The other rollers are free to rotate in their ball bearings. Each non driven roller has an axially projecting shaft on which a sprocket is mounted on a ball bearing so that the sprocket is free to rotate relative to the shaft. All these sprockets are driven by an endless chain so that a low torque equal to the bearing friction is applied to each roller.  This torque balances the friction torque of the bearings which support the rollers, so that no tension is imposed on the strip of material being heat treated. USE - Heat treatment of flat flexible material.
