Patent DE-3835904-A1 (DE)
IPC: F16K17/38
Filed: 1988-10-21
Abstract: The safety valve has a valve body (6) which is held in its open position by melt material (8). When an excessive rise in temperature takes place, the melt material (8) liquefies and releases the valve body (6). The latter travels, under the action of a spring (7), into a valve seat (5) which is defined by an inlet opening (2) of a shut-off fitting (1) accommodating a shut-off element (4). Between the valve seat (5) and a  complementary inclined surface (14) of the valve body (6) there is produced a heat-resistant metallic seal which, as the temperature increases, is secured against its guide by a thermal prestressing of the valve body (6). <IMAGE>

Inventor: ZELLER ROLF DIPL PHYS
IPC: C23C14/22
Filed: 1989-04-26
Abstract: The apparatus has a vacuum chamber (10) with an anode (11). A loading plate (16) for the substrate (18) to be coated is arranged as a first cathode, a distance away from the anode (11). A volatilisation electrode arrangement (40) of the nonvolatile substance to be transported is arranged as a second electrode a distance away from the anode (11) and from the loading plate (16) in the vacuum chamber (10). Furthermore, the discharge voltage source (24) for generating a potential difference between the anode (11) and the first cathode (16) and a volatilisation voltage source (44) for generating a potential difference between the anode (11) and the second cathode (40) are provided. A reactive gas is passed into the vacuum chamber (10) through a reactive gas pipe (32) entering the vacuum chamber (10). A gas mixture of a reaction gas and a carrier gas can be passed into the vacuum chamber (10), through a reaction gas and carrier gas pipe (52), in such a way that the volatilisation electrode arrangement (40) is surrounded by the gas mixture of the reaction gas and the carrier gas. The transport compound, which may be dangerous, can then be synthesised within the receptacle of the vacuum chamber (10). Sufficient coating even of part surfaces of the substrate (18) which point towards the loading plate (16) is ensured by the unoriented distribution of the transport compound in the vacuum chamber (10) and the essentially omnidirectional field distribution of the electric field around the substrate (18). <IMAGE>

Date May 16, 1991.A process and a device for automatic determination of parameters for process control systems with unknown transfer behavior are useful for controlling special technical processes in which a functional relationship between process input and process output variables is unknown, at least in parts, while maintaining the properties of the output variables (target functions) within certain acceptable limits. To this end, measured values obtained by the process are subjected to statistical analysis from which control parameters such as theoretical value functions and weighting factors are derived automatically and incorporated in a universally applicable control specification. The control specification is used to determine the control parameter. Adaptation to different processes as well as suitability tests for various control parameters for process control can be carried out comparatively simply using predetermined calculation procedures, conversion factors or the like.
