Patent DE-3327242-A1 (DE)
Inventor: SOBINGER DIETRICH E
IPC: B63B38/00
Filed: 1983-07-28
Abstract: Installation for towing with the boat an enveloped iceberg respectively a resultant water-bag (1). The water-bag (1) has at least at one towing end a tow-bar (9) which is transversal with respect to the towing direction. On the tow-bar (9) are attached rolls (a, b ...) of loops (4) next to each other and used as flexible traction mechanisms. Tow neighbouring loops (4) of a row of loops are connected by another loop in order to form the following row of loops which comprises consequently one loop less until, after forming an acute-angled towing net (5), only one loop or more loops remain to attach the water-bag to a tow-boat. Thereby a uniform distribution of the traction force and a reduction of specific stress in the loop areas are obtained so that the problems of towing the water-bag are eliminated thereby making the towing operation possible with a reduced slide friction coefficient.

Title: Self locking hydraulics for the movement of jig-and-fixture and machine parts
Inventor: OERTEL RUDOLF DIPL ING
IPC: F15B15/26
Filed: 1983-09-01
Abstract: In order to achieve a "self locking" of a hydraulic piston (1), which is intended to move machine jig-and-fixture parts, in the hydraulic cylinder (3), without in so doing having to use an additional, separately controlled pressure medium, it is proposed to arrange tangential pairs of spring steel tapered sleeves (6 - 7) and (8 - 9) at both ends of the hydraulic piston, the inner rings (6) and (8) each being firmly shrunk onto the piston, and the outer rings (7) and (9) being pressed by springs (12), which are supported in the piston, in the direction of the piston end onto the wall of the hydraulic cylinder. By alternating admission of pressure medium to the end faces of the piston, the outer sleeves are moved against the spring force, thereby releasing the braking grip on the cylinder wall, on that facing the pressure medium by means of the medium itself, on that remote from the pressure medium by the friction force on the cylinder or alternatively also by means of the pressure medium, in that the inner sleeves are mounted on sliding bushes (20) guided in the piston, which bushes are braced with one another by pushrods (22), which run through corresponding bores in the piston. <IMAGE>

Title: Process and apparatus for secondary clarification of mechanically prepurified waste water
Inventor: BECHTEL HANS
IPC: C02F1/00
Filed: 1984-09-18
Abstract: A process of this type operates by the principle of the immersion percolating filter. It is characterised in that the clarifying substance support used is a particulate packing material in the form of an immovable filling and in that the incoming, prepurified waste water is elevated from a minimum level essentially exposing the packing to the atmosphere to a maximum level surrounding the entire packing with waste water. During the elevation of the water level and because of the immersion of the packing in the waste water effected as a result, the secondary clarification is effected. After the upper level is attained, the waste water treated by secondary clarification is relatively rapidly discharged, whereupon the procedures are repeated. A corresponding apparatus for carrying out the process contains in a chamber the particulate packing material as an immovable filling and is furnished with an outlet device such that when the upper level is attained, it is automatically operated.

Title: Method and apparatus for the production of a multi-groove driving pulley made of sheet metal
Inventor: FRIEDRICHS GERD
IPC: B21D53/26
Filed: 1984-12-17
Abstract: The invention provides a method for the production of a multi-groove V-belt pulley made of sheet metal, which has a circular base 3 which merges into a cup-shaped groove part 5, 6, 7. During this process, an essentially cup-shaped preform with a uniform thickness corresponding to the thickness of the circular base 3 is first of all produced. A conical form widening outwards away from the circular base 3 is imparted to a section 6 of the preform in the cup-shaped groove part. The preform is clamped fast in a chuck, the mandrel 8 used for the deforming process having a conical contact surface 11 and being arranged opposite a smoothing roller 15. By pressing this smoothing roller 15 against the mandrel 8, the section 6 is deformed in such a way that the cross-section situated at the base 3 is thickened and the cross-section decreases in a constant fashion towards the outside. Flanges corresponding to sections 4, 5 and 7 are formed integrally on both sides of the groove part corresponding to section 6. <IMAGE>

Patent DE-3500870-A1 (DE)
Title: Bracket-type support for shelf plates
Inventor: KALINNA JUN ERWIN
IPC: A47B96/06
Filed: 1985-01-12
Abstract: A bracket-type support for a glass plate 1 consists of a light metal extruded profile with a vertical baseplate 2 from which two horizontal arms 4, 5 extend which receive the glass plate 1 between them. The lower arm 4, seen in cross-section, is far longer than the upper arm 5, but less than half as wide as the glass plate, such that the centre of gravity S of the glass plate lies before the outer edge 6 of the lower arm 4. Near to this outer edge 6, the surface of the lower arm 4 is provided with a longitudinal groove 8 in which a rubber cord 9 is inserted. Due to its own weight, the glass plate 1 is pressed so firmly, on the one hand, against the underside 10 of the upper arm 5 and, on the other hand, against the rubber cord 9 that a surprisingly firm, non-positive fastening of the glass plate 1 is produced. To facilitate the introduction of the glass plate 1 between the arms 4, 5, the spacing a between the arms 4, 5 on the baseplate 2 is so large that the glass plate can be pushed obliquely upwards between the arms 4, 5 without coming into contact with the rubber cord 9. <IMAGE>
