Title: Through-scavenging engine with rotary valve, and separate scavenging and charging
Inventor: EICKMANN KARL
IPC: F01L7/02
Filed: 1988-06-27
Abstract: In the two-stroke engine of the main patent P3817529.0 two rotary valves are according to the invention assigned to the cylinder head close to the upper end of the cylinder. From an air feed unit, for example the inside of the crankcase or a fan or supercharger, scavenging air is fed to one of the said valves, which serve as inlet valves for the cylinder. From a second supercharger supplying at supercharging pressure, charge air or fuel-air mixture is fed to the second of the inlet valves. The inlet valves open and close successively so that the cylinder is first scavenged after completion of the exhaust and the cylinder is then charged at supercharging pressure after closure of the outlets. The inlet valves are designed as rotary valves, which may also be valves swivelling or rotating about their axis. In another embodiment, nested lifting valves with large flow cross-sections are used. The advantages of the invention over the prior art are described with reference to an example of a known two-stroke engine cylinder and the rotating mass and the kinetic energy of the flywheel mass of the crankshaft are calculated in a mathematical geometry figure. Through the invention the engine achieves through-scavenging, scavenging and charging with clean operation as in a four-stroke engine and the engine power for a given weight and size is increased.

Patent DE-3829837-A1 (DE)
Title: Modular construction system for concrete cellars and silos and similar structures
Inventor: KLASEN ANTON
IPC: E04B1/00
Filed: 1988-09-02
Abstract: The present system is made up of a row of precast concrete parts which vary in their form. Common to all the parts, however, is the type of screw-connection and, consequently, the construction of the edges, which are configured in the form of steps. The corresponding parts thus fit accurately one inside the other. These parts are screwed on one another by using a corresponding seal and screw-connection. The screw-connection has been dealt with in detail in another application. Screw-connecting the parts has considerable advantages with respect to other processes of concrete construction work. By virtue of immediate screw-connection, the structural parts are more stable and accidents due to parts falling over are avoided. Furthermore, the parts connected in this manner are flexible and absolutely leak-tight. In addition, the structures can be taken apart again and reused. It is just as simple to build onto such prefabricated structures and to enlarge the same. The erected structures can be used immediately, there are no longer any delays in construction.

Patent DE-3832626-A1 (DE)
Title: Special disposal unit with active asphalt seal
IPC: B09B1/00
Filed: 1988-09-26
Abstract: Special waste of any type can be stored for the long term safely separated from its environment in a special disposal unit in the form of a large concrete container which is effective for a virtually unlimited period on account of the sealing compounds used. Subsequent repair of defects, which hitherto could only be achieved in a technically unsatisfactory manner, is dispensed with. It is possible to check the effectiveness of the seal at any time by observing the asphalt level or it is even possible to subsequently recover the stored waste. To this end, hollow bodies placed one inside the other and separated from one another by a gap filled with sealing compound are let into the subsoil. The hollow bodies are made one after the other. Asphalt is then poured as sealing compound into the annular gap between both hollow bodies so that the stored special waste is safely separated from the environment. The liquid sealing system of asphalt provides a completely tight and permanent seal. In addition, the self-healing effect of the asphalt, which penetrates into any cracks in the subsoil or concrete and thereby always guarantees the sealing, should be emphasized. <IMAGE>

Title: Intermediate support for support arrangements having large temperature differences
Inventor: HAACK THEODOR
IPC: F16L59/135
Filed: 1988-10-31
Abstract: Objects having high temperature differences can be stored reliably and without danger for the respective process or the heat balance with respect to the undersurface by arranging an insulating-material layer, stabilised by means of a supporting framework, between the object and the support. The thickness of the insulating-material layer is adjusted so as to correspond to the insulation resistance to be achieved, whilst the forces are taken over and transmitted, first of all, by this layer, preferably correspondingly thickly constructed mineral wool, and by the metal sheet which mostly forms the side walls of the corresponding insulating-material block. With the aid of such an intermediate support, temperature losses can be avoided by up to around 90%, so that in the respective object, an impairment of the process does not occur, at the same time, however, reliable and uniform supporting of the entire object by the intermediate support is ensured. <IMAGE>
