Patent DE-3118406-A1 (DE)
Title: Pneumatic vehicle tyre
Inventor: KUHN DIETER DR
IPC: B60C11/12
Filed: 1981-05-09
Abstract: These pneumatic tyres have in their tread wave-shaped fine indents in the profile elements which are realised, for example, as ribs or blocks. Furthermore, the invention is also based on such fine indents which terminate at their ends in an elongated fashion and end in grooves which bound the profile elements. In order to achieve an improved resistance to further tearing in the region of the ends of the fine indents which terminate in an elongated fashion, in this area of the fine indents their depth is substantially less than that at the other sections, these depths varying in a ratio of approximately 1:2. In a known manner, the depth here of the wave-shaped part also corresponds to the depth of the grooves which bound the profile elements.

Title: Plant for the recovery of energy and raw material from combustible residues
Inventor: FRANK HANS
IPC: F23G5/46
Filed: 1981-07-02
Abstract: By combining individual plant components in a certain manner, various processes for the thermal treatment of combustible residues are made possible. Provision is made in the plant for various processes required by combining the chamber, for the continuous combustion or degasification, with a distillation column and two downstream heat exchangers, connected by conduits, gates and valves. Combustion gases of the modulating burner device of the heat exchanger flow, in the heating-up phase, up to the designated operating temperature, through the chamber and are passed to a stack. Simultaneously with the first charging process of the chamber, the conduits are controlled in such a way that the hot off-gases of the burner device are in contact with the convection surfaces of the heat exchanger and, via the second heat exchanger, are passed to the chimney, optionally either directly or via an off-gas fan. By virtue of a special arrangement of the gates and valves it is possible to pass to the chamber, directly or indirectly, a branch stream of hot off-gases from the first heat exchanger or, optionally, cold or preheated combustion air or, optionally, a mixture, for the purpose of thermal treatment of the residues for each particular case.

Title: Infinitely variable mechanical intermittent-motion mechanism
Inventor: RINDFLEISCH BERNHARD
IPC: F16H29/08
Filed: 1983-03-14
Abstract: The mechanism, which is constructed with the aid of intermittently acting members, serves for infinitely variable speed or torque conversion of driving motors connected to its input side and, due to a special series connection of precisely matched pendular members, freewheel switches and a differential gear, guarantees exact synchronism of the output shaft irrespective of the transmission ratio setting. In this arrangement, the input shaft (1) drives two pendular systems (2, 3), which are of identical construction but operate with a 90 DEG phase shift relative to one another and comprise pendular members engaging positively in one another. Each of the two pendular systems converts the uniform rotary motion of the input shaft into in each case two pendular motions which are phase-shifted by 180 DEG relative to one another and obey a speed-time law having characteristic properties. The travel of the pendular systems can be adjusted synchronously and in an infinitely variable manner relative to one another. The travel adjustment (4) is constructed in such a way that the characteristic properties of the pendular motions are maintained. Each pendular system drives a pair of freewheel switches (5, 6 and 7, 8) which are arranged on a common intermediate shaft. The two coaxial intermediate shafts (9, 10) are connected to a bevel-gear differential (11), the planet carrier (12) of which is coupled rotationally to the output shaft (13). <IMAGE>

Title: Method for manufacturing roof and floor supporting frameworks from prefabricated components and a beam system for carrying out this method
Inventor: AN HAACK HERBERT
IPC: E04B5/14
Filed: 1983-05-19
Abstract: The subject-matter of the invention is preferably intended and suitable for wide-span supporting structures made of reinforced concrete for roofs and floors. Its advantages in this field lie in the comparatively small linear dimension of the prefabricated parts used and in the favourable structural conditions of the supporting frameworks manufactured therewith. The latter is due to the crosswise connection of the beams in an arrangement offset from axis to axis, which is characteristic of the system, and to the rigid connection of the beams at all points of intersection. Compared with three-dimensional supporting frameworks made of metal, an embodiment of a supporting framework according to the invention has advantages in the area of fire protection; furthermore, it is possible to dispense with rust- and corrosion-protection measures. In an embodiment of the supporting framework made of wood, steel or other materials according to the invention, the advantages of the small linear dimensions of the prefabricated parts and the favourable structural conditions are likewise obtainable. Irrespective of the choice of material, advantages in terms of efficiency with regard to construction times and costs can be expected owing to the connection devices belonging to the invention.
Patent DE-3320882-A1 (DE)
Title: Electroluminescent element
Inventor: SATO RYO
IPC: H05B33/14
Filed: 1983-06-09
Abstract: An electroluminescent element is specified whose light colours change in accordance with the r.m.s. value or the frequency of applied voltages. The electroluminescent element is provided with at least two types of luminescence centres in a matrix which in each case form dedicated local levels, and has at least two light regions, corresponding to the respective luminescence centres, the characteristics, which represent the relationship between the light intensity and the applied voltage or its frequency, of the light emitted by the luminescence centres being different from one another. These light regions are typically formed from at least two types of activators which are diffused at a respectively different concentration into a single matrix material and are microscopically mixed therewith. The respective light intensity of the light of different colour which is emitted by the respective light region changes as a function of the external voltage or its frequency. The proportion of the light-emitting diode of the respective light colour can thus be controlled by means of the applied voltage or its frequency. In this way, the colouring can be changed.
