Abstract: A method for processing seismic data is provided, in the method a new attribute indicating rock fabric properties of a subterranean section of the earth is processed from reflection seismic data obtained from the subterranean section of the earth. The processed rock fabric attribute may be used to determine properties of and/or generate an image of the subterranean section of the earth.

Abstract: The invention relates to a cold gas generator with a pressure tank (1), which can be filled with compressed gas and comprises a closed base at one end and a tank opening at the other end, wherein an electrically drivable closure device can be inserted into the tank opening, which closure device is energized in a working position and opens an outlet opening of the closure device.

Abstract: The invention relates to a closure apparatus for a pressure container (14), which can be filled with compressed gas, of a cold gas generator (11), wherein the pressure container (14) comprises a closed base at one end and a container opening (16) at the other end, on which container opening (16) the closure apparatus (12) can be arranged for forming a cold gas generator (11), having a valve body (48, 71) which, in a rest position, closes an ejection opening (18) which communicates with the surroundings, and which valve body (48, 71) can be transferred into a working position by way of a drive apparatus (31) for opening the ejection opening (18), wherein a device (33) which reduces the closing force to be applied and actuates the at least one valve body (48, 71) between a rest position and a working position is provided between at least one valve seat (51) of the ejection opening (18) and the drive apparatus (31).

Abstract: The invention relates to a closure device for a pressure reservoir (14) of a gas-refrigeration generator (11), which pressure reservoir can be filled with a compressed gas. The valve body (21) is arranged so as to be displaceable inside a valve box (18). The valve body (21) has an effective compressive surface facing the main chamber (15) and an effective compressive surface facing the prechamber (52), both surfaces having identical size and being impingeable with the filling pressure of the main chamber (15). The valve body (21) is retained in a closed position by an outer effective compressive surface (64) which is subject to an atmospheric pressure in the direction of closure and by an energy storing element (47).
