Abstract: Device for reducing the risk of fire or delaying the ignition of flames in preferably large open or roofed storage tanks for combustible liquid media covered by floats, such as crude oil or the like, comprising a fixed cylindrical cavity as a tank for receiving the liquid, which tank is provided with a further protective barrier surrounding it at a certain distance and serving as a collecting chamber in case of leakage. The device is characterized in that the tank, if applicable the collecting chamber, contains floating cover bodies made of rolled-up stretched material that rest in a fined-up manner floating on the surface of the liquid, whereby polyurethane foam is inserted into the interior of the cover bodies, serving as a floating agent.

Abstract: Gas container and method for filling a container with gas. The method includes inserting an electrically conducting stretched material into the container before inserting gas into the container, electrically connecting to an electrical ground and at least one of the electrically conducting stretched material and an area in a vicinity of an outlet opening of a filling pipe for inserting the gas into the container, and inserting gas into the container under compression.

Abstract: The invention relates to a method for filling a container with gas, gas being inserted into the container under compression. In order to be able to fill the container with a larger amount of gas than before and to reduce gas pressure peaks during filling, it is proposed according to the invention that electrically conducting stretched material is inserted into the container before it is filled with gas. Furthermore, the invention relates to a gas container (1), in particular a high-pressure gas cylinder, for storing gases under pressures exceeding 50 bar, in particular exceeding 200 bar, which contains electrically conducting stretched material (11). With gas containers (1) according to the invention, a higher filling level is achieved than before with a given pressure. Containers with a small wall thickness can be used without a safety risk because of a reduction of gas pressure peaks in the interior of containers.

Abstract: A device is proposed for producing expanded flat material, comprising a cutting and expanding device and a coiling device, the starting material for which is a foil web, the expanding device having toothed belt pairs or the like conveyor means guided over partially driven deflection rollers, which conveyor means hold the foil web at the edges and makes it advance and gives the expanded strip a uniform structure over the entire width. This is characterized in that the expanding device on both sides of the foil web has respectively one toothed belt pair that guides the foil web vertically upwards with one lateral edge, starting from the horizontal plane, via hinged, optionally rigid, sliding blocks arranged in the interior area of the toothed belts, while the other lateral edge of the foil web is guided vertically downwards in the same manner, i.e., forming a scissor movement, and an expansion of the foil web is formed across the resulting diagonal.

Abstract: A structural element for use as a carrier body in a catalytic process, condenser body or filter is formed by unwinding a foil from a roll, forming staggered cuts in the foil, and stretching the foil transversely to convert the cuts into hexagonal apertures interconnected by webs which become twisted to provide the sheet with a depth dimension. The sheet can be cut to length and layered with other like sheets in a flat or rolled form.

Abstract: A method of and an apparatus for the performance of the method for the fabrication of dimensionally stable, cylindrical filler bodies for increasing the surface area in receptacles, e.g. for the protection against explosive combustions, consisting of foil-like, preferably corrosion resistant material strips, especially consisting of metal, paper, paper board, synthetic material or a combination by coating, which allows a continous fabrication without requiring oscillating masses in the machine parts. The aim is reached by a foil strip which receives perforated cutting spots, staggered transverse to the conveying direction, the cutting spots stretched to the breadth and folded, lopped in pieces, cylindrically bent so as to be round, twisted at the ends and continously rolled into cylindrical bodies.
