Patent EP-0232766-A2 (EP)
Inventor: SCHROEDTER KLAUS
IPC: C22B13/08
Filed: 1987-01-22
Abstract: Mineral acids are freed from heavy metals, especially copper, arsenic, antimony and lead by precipitating the metals in sulfide form. To this end, the mineral acid is reacted with hydrogen sulfide or an alkali metal sulfide solution under pressure and with thorough agitation, and formed solid matter is subsequently separated from the mineral acid under the pressure selected. The mineral acid may conveniently by admixed initially with a filter aid and then treated with hydrogen sulfide or the alkali metal sulfide solution.

Abstract: A closure for a pressurized container, such as a coolant radiator, provides overflow protection by means of a tube connecting the highest point of the container with the filler neck. The end of the tube in the filler neck is closed by a cap having a high pressure relief valve. The closure cap also contains a low pressure relief valve connected to the tube which, together with the high pressure relief valve, maintains a pressure balance in the container without substantial change in the amount of fluid therein. Both valves are connected directly to a bleed line to atmosphere or a reservoir. The tube and filler neck together serve to regulate the pressure in the container and to provide a maximum fluid level within the container.

Abstract: A hydro-ball in-core instrumentation system for a nuclear reactor (48, 50, 52) for measuring the core reactivity, employs detector strings (40) having radiation sensitive balls (84) spaced, threaded and fixed on each string; the opposite tip ends of each string are transportable by fluid drag for transport­ing the detector strings (40) from stored positions in an exterior chamber to inserted positions within the instru­mentation thimbles (150, 352) of the fuel rod assemblies of a pressure vessel (50) from the bottom or top, and for return. The coolant pressure within the detector passageways is the same as that within the vessel (50).

Abstract: New car bodies are coated with an external preserving agent, in particular wax, as a temporary transportation protection, the windows being included in the coating process and thus becoming nontransparent. However, in order to transfer the motor vehicle from the production belt to the storage place or loading railway station, the required view must be ensured for the driver. Therefore, a device is provided, by which means it is possible to remove the layer of preserving agent from the windows in a manner which is economical, automatable and capable of integration into the production process. The device consists of a robot arm which can be moved in a controlled fashion at least in one direction perpendicular to the movement of the vehicle body, a wiper strip whose length is essentially the same as the height or length of a vehicle body window, and a wash tank whose length exceeds the length of the wiper strip and of the washing liquid inlets and has on its lower side a washing liquid outlet, the wiper strip being movable and/or swivellable by the robot arm between a position in the wash tank and a position on the vehicle body window. <IMAGE>

Abstract: A section (10) permitting securing to walls, which serves to form a shadow gap (24) and/or a lighting groove (40) and also to receive the edges of lining panels or plaster bases. The section (10) has a first section part (12), which is to be attached to the wall, and a second section part (14), which extends at right angles thereto and receives the edges of lining panels or plaster bases. Projecting downwards from the second section part is a first rib (18, 18', 46), thereby forming, between it and the wall plaster, the shadow gap (24) or lighting groove (40). The edges of the lining panels or plaster bases are fastened to the second section part (14) outside the first rib (18, 18') (seen from the wall). The shadow gap (24) can also be provided between the first rib (46) and the outer edge of a wooden ceiling (30). The section can have, between the first rib and the side bearing on the wall, a further rib (35, 35') of greater height, which specifies the thickness of a plaster layer in relation to the wall. The section (10) can have a transition portion (63) which leaves open a space and permits the section parts to move relative to one another, thereby preventing the formation of cracks in the plaster. <IMAGE>

Abstract: A method and apparatus is disclosed for leak testing a fluid containing chamber wherein the chamber is pressurized with a gas and is submerged in liquid. The bubbles of gas rising from the submerged chamber are directed past a predetermined location which is adjacent to a photoelectric detector. The electrical signals from the photoelectric detectors are counted and when the number bubbles exceeds a predetermined number a fault signal is activated indicating a leaking container. By grouping a number of adjacent photocells into a predetermined set, the apparatus can discriminate between random bubbles rising from the chamber as it is submerged, and a number of bubbles all originating from a given location.
