Title: Arc-extinguishing chamber
Inventor: GREEFE KLAUS DIPL ING
IPC: H01H73/18
Filed: 1982-12-23
Abstract: An arc-extinguishing chamber comprises an extinguishing- or cooling-plate arrangement (56, 14) which is dedicated to the contact point (26, 28; 48, 50) of a switch (10, 14), a switching arc, produced at the contact point, passing into this arrangement, where it is cooled and extinguished. To improve the extinguishing or cooling properties, each plate (14, 56) is coated, at least on one side and at least in part, with a material which gives off gas or vapour and which, under the influence of the arc, evaporates and affects the arc. In this arrangement, a coating-free area (66, 68, 70) is advantageously left free. The material used can be zinc or an insulating material. If zinc is used, the optimum solution is to coat only a subregion (72) situated downstream. <IMAGE>

Patent DE-3315056-A1 (DE)
Title: Electrohydraulic directional control valve
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F15B13/043
Filed: 1983-04-26
Abstract: An electrohydraulic, pilot-controlled directional control valve (10) having a spool (27) with variable overlap is proposed which in the normal regulating operation works with zero overlap of its control edges (35 to 38) and for a safety function in an emergency safely shuts off an inflow chamber (16) by positive overlap of the allocated control edges (36, 37) and relieves two motor chambers (17, 18) to the return. The spool (27), lying in a position-control circuit (13), consists of two parts (28, 29), the outer piston-like sections (31, 34) of which can be acted upon at the end face by a control pressure. Their inner piston-like sections (32, 33) abut coaxially in the inflow chamber (16), have one pressure face (55, 56) each, and together carry a sleeve (52) which seals off a parting line (41) with a hollow space (43) which is relieved to the tank (26) and in which a second stop (48) lies which limits the stroke distance when the spool parts (28, 29) are spread apart. If the pilot control (12) fails, the pressure in the inflow chamber (16) presses both spool parts (28, 29) apart by the stroke distance as a result of the control chambers (22, 23) now relieved of the control pressure, so that the inflow chamber (16) is now safely shut off by control edges (36, 37) with positive overlap and the motor chambers (17, 18) are relieved. <IMAGE>

Patent DE-3342847-A1 (DE)
Title: Chemical heat storage installation
Inventor: ARRAS GEORG
IPC: F28D20/00
Filed: 1983-11-26
Abstract: The basic concept of the chemical heat storage installation is the carbon cycle in nature, starting from the carbon or the wood that is burnt in a stove. Carbon and oxygen combine while giving off the solar energy they have stored - exothermally - to give carbon dioxide. Said carbon dioxide is stored intermediately in the atmosphere, until it is once more dissociated into oxygen and carbon, endothermally, in the biochemical process under the influence of sunlight and chlorophyll, the carbon being stored intermediately in the plant - coal -, and the oxygen being stored in the atmosphere. Upon combustion of the wood or the coal the cycle recommences. This carbon cycle, because of the dissociation of carbon dioxide, is, however, extremely difficult to implement. It is easier, for example, to break down water into hydrogen and oxygen, or aqueous ammonium hydroxide into water and ammonia - endothermally. By using a high-temperature solar installation - solar grill - P3342846.8, it becomes possible to store the solar energy without limitations.
Patent DE-3403677-A1 (DE)
Inventor: GORSKI WERNER
IPC: G05B19/4069
Filed: 1984-02-03
Abstract: A process for generating a data structure of a computer model of a processed workpiece. The contours of the workpiece and the cross section of the tool, as well as the path movement of the tool, are analyzed in a grid such as is presented by a raster picture screen and associated image point memory of a microprocessor controlled graphic control unit of a numerically controlled machine tool. At each point of the coordinated grids the height of the workpiece is linked with the programmed processing depth of the tool and in this way the altered data structure of the workpiece is determined. The altered data structure can serve for the representation of the computer model thus determined on a picture screen. The linkage of the data from grid point to grid point is thus reduced to a number comparison for the Z coordinate, thereby maintaining both computer and apparatus capital expenses at a low level.

Patent DE-3414821-A1 (DE)
Title: Seal arrangement
Inventor: BECK HUBERT
IPC: F16J15/56
Filed: 1984-04-19
Abstract: The intention is to design a seal arrangement for providing sealing between two cylindrical parts movable relative to one another in such a way that less expensive, more reliable, and simple shaping as well as simple installation of the seal are possible. To solve this problem, at least two seals provided with different outside diameters are arranged in such a way in an undercut-free location hole open towards the interior space that the seal with the largest outside diameter faces the interior space and the next-smallest seal adjoins it towards the outside. A disc serving to provide support is arranged between respective pairs of adjacent seals. The advantage here is that additional sealing between the individual seals can be dispensed with, as can production of the difficult individual grooves serving to accommodate the seal.
