Title: Process for the preparation of substances consisting of components which are poorly miscible with one another, in particular metallic substances
Inventor: FUCHS ERIK DIPL ING DR
IPC: C22C1/02
Filed: 1982-10-08
Abstract: In industry there is a need for substances (also for the production of sliding bearings) whose components are usually immiscible or only poorly miscible with one another. Particularly in the case of components which have only a limited miscibility with one another even in the molten state and large differences with regard to the density and the melting point, the necessary fine distribution and the uniform composition cannot be achieved by the known methods. According to the invention, a melt which is at least partially homogeneous is prepared from the components, this melt is cooled to a temperature below the solidification temperature at a cooling rate which is greater than the critical cooling rate, auxiliaries are optionally added to the material, the material is then compacted mechanically and/or thermally and, if desired, its properties are further modified - in particular by plastic deformation or heat treatment. The process according to the invention permits the preparation of microscopically homogeneous intermediates from substances which are so poorly miscible with one another that even their melts tend to exhibit phase separation.

Patent DE-3247110-A1 (DE)
Title: Ship's drive
Inventor: KUEHN WILLY
IPC: B63H11/08
Filed: 1982-12-20
Abstract: The invention is based on the fact that the water resistance of a ship is removed in front of the bow, is passed through the ship and thrust out in an accelerated fashion at the stern, where it pushes against the massive wall of water behind the ship. The ship can thus achieve a higher speed with a lower driving power. The external shapes can to a large extent be adapted to take account of the fact that there is only a small amount of water resistance to be overcome. A dimensionally more favourable shape can thus be obtained. The necessary compression of the water to be thrust out at the stern is influenced not only by the engine power but also by the diameter of the tubes. In order to avoid too large fluctuations in the water through-flow speed, which are caused for instance by the direction of movement of the seawater surrounding the ship, a means for regulating the inflow of water at the bow can be installed, with automatic actuation if required , which means is controlled by the speed at which the water is flowing through just ahead of the acceleration system for the water. If part or the entire amount of the water picked up at the front is not thrust out of the stern but rather at one side, the direction of movement of the ship can be much more quickly changed. By thrusting out the water forwards, the ship can be brought to a standstill much more quickly. Thus even large ships can be berthed and cast off in the harbour without using external aid, and collisions in open sea can also be more easily avoided.

Title: Two-stage or multi-stage water-level control for steam generators
Inventor: FRICKE KARL HEINZ DIPL ING
IPC: F22D5/26
Filed: 1983-04-14
Abstract: In order to achieve, in steam generators with two-stage or multi-stage control of the water level, a simultaneous throughflow of feed water and flue gas in the feed-water preheater, the feed pump is only switched on when the furnace is working, and the highest water level is not reached, or when the lowest water level is reached. Furthermore, the feed-water flow or the furnace capacity is limited in such a manner that the feed-water flow corresponds to a great extent to the quantity of steam generated at the respective furnace capacity. The limitation of the feed-water flow can take place by means of a throttle with bypass lines, which can be connected in a stepped manner, in the feed-water line, by means of a speed control of the feed pump or other means.
