Patent DE-3807467-A1 (DE)
Title: Eigentone sound unit
Inventor: SASSMANNSHAUSEN WERNER
IPC: G10D13/08
Filed: 1988-03-08
Abstract: A structurally simple eigentone sound unit or idiophone sound unit 1 with a sound body and a resonance body assigned to this is proposed. It is characterised in that, on a hollow body 2 which consists of a bottom 3, of a top 4 and of a casing 5, 6, 7 which is open in places, and which is assembled in a modular manner, the top 4 alone forms the sound body while the bottom 3 with the casing 5 to 7 and the top 4 is effective as the resonance body. The fine tuning of the eigentone sound unit 1 is brought about by the top 4 of the hollow body 2 being provided with tuning depressions, e.g. channels, grooves, slots, blind holes, holes or the like, which reduce its wall thickness at least in places. <IMAGE>

Title: Method for removing metal impurities on semiconductor crystal surfaces
Inventor: SCHAEFER HELWIG DIPL CHEM DR
IPC: H01L21/306
Filed: 1988-07-01
Abstract: In a method for removing metal impurities on semiconductor crystal surfaces, the precleaned basic cleaning media are systematically admixed with complexing agents whose complex formation constants are large enough to preclude, in the pH range selected, the formation of hydroxides. The cleaning effect on silicon crystal wafers is improved, compared with the known processes, with the admixture of, for example, ethylenediamine tetraacetate to a hydrogen peroxide solution, by a factor of from 10 to 100 (decrease in the impurities by a factor of from 100 to 1,000). The method is used in the fabrication of very-large-scale-integrated (VLSI) semiconductor circuits.
Patent DE-3824777-A1 (DE)
Title: Positively locking, weld-free, solder-free and beading-free O-ring/shafted sealing cone pipe connection
Inventor: KULLIK WOLFGANG
IPC: F16L19/03
Filed: 1988-07-21
Abstract: In order to reduce leakages in pipeline systems in predominantly hydraulic installations for the high-pressure and low-pressure ranges up to 320 bar, as an alternative to the known metallically sealing cutting-ring pipe connection systems, a pipe connection system has been invented which, just as the weld-on cone pipe connection system which is generally recognised as being reliable, uses a sealing cone with elastic O-ring sealing. The problem with the connection between shafted sealing cone and the pipe which is to be connected has been solved in that a pipe is equipped with an associated conical union nut, a fitting deformation wedge ring and a shafted sealing cone which fits, with the shaft, accurately into the internal diameter of the pipe and exhibits a recess behind the shoulder of the sealing cone and a sealing ring at the beginning of the shaft. By screw-connecting said pipe, which is fitted out in this manner, to a screw-connection body in accordance with DIN 2353 or ISO 8434, while maintaining a minimum tightening moment, the positively locking connection of the shafted sealing cone to the pipe takes place. The leaktightness of this connection is ensured by the sealing ring on the shaft and a metal adhesive with which the shaft is additionally provided. By sinking the pipe wall into the recess of the shafted sealing cone, a metallic sealing, furthermore, results.

Title: Method for laying an optical cable
Inventor: GROEGL FERDINAND
IPC: G02B6/44
Filed: 1988-09-20
Abstract: A method for laying an optical cable as well as empty cables and optical cable elements for use in this method are described. The laying is carried out essentially in two steps, the first step being the laying of the empty cable in a manner known per se, and the second step being the drawing in of optical cable elements into the empty cable. The optical cable thus produced is longitudinally waterproof, provided the empty cable contains a material which results in longitudinal waterproofness, preferably ex factory. <IMAGE>
Patent DE-3835809-A1 (DE)
Title: Noise capsule for an internal combustion engine
IPC: F02B77/13
Filed: 1988-10-21
Abstract: The invention proceeds from the usual single-shell sound-insulating encapsulation for the drive assemblies or internal combustion engines of motor vehicles. The disadvantage of the known solutions is that sound-insulating materials known to be particularly effective have had to be avoided owing to their deficient heat resistance or the distance from the sound-radiating surface had to be made correspondingly large. The invention solves the problem by means of a two-shell encapsulation, in which the inner capsule, in addition to the sound insulation which it also produces, is responsible for the thermal shielding, whilst the lacuna can now be made from especially suitable material without regard to the thermal load capacity of the materials used.

Title: Apparatus for the manufacture of dowels, preferably wooden dowels
Inventor: FISCHER WALTER
IPC: B27M3/28
Filed: 1988-11-17
Abstract: With the apparatus intended for the manufacture of wooden dowels, it is possible to manufacture, in a cost-effective manner, dimensionally accurate dowels which, in addition, can be inserted considerably more easily into the cylindrical bores of the parts to be joined. The dowel rods provided for the manufacture of the dowels are individually notched over the intended dowel length in a notching station arranged above a revolving conveying device and are cut at the deepest point of the notches. For this purpose, the notching strips of the notching station are arranged inclined in the conveying direction, there being arranged, at the end of the notching strips, in each case a knife which is guided beyond the lower boundary of the notching strips and has a conically extending cutting edge. The through-passage of the dowel rods takes place by means of frictional engagement with the conveyor belts. By cutting the dowel rods, no material losses occur. After the cutting, the dowels have a bevel at their ends owing to the notches which have been made.
