Abstract: ABSTRACT       A method and an apparatus for collecting oil and gas flowing uncontrolled into a body of water beneath the water surface, especially in a blow-out from a point at the sea bed.          The oil and gas discharged from the blow-out location is caught and ascends towards the surface within a tubular shell body and the gas is collected in a floating gas bell provided at the upper end portion of the shell body which bell forms a gas or liquid trap against the surrounding water in that it has an outer wall projecting downwards and surrounding an upper portion of the  shell body.  The gas is thus automatically placed under a controllable positive pressure in that the displacement of the gas bell in the medium within the shell body can be varied by ballast means.   The apparatus includes an upper member con-stituting the gas-collecting bell, and a lower member constituted by the shell body.  The upper member comprises a shell-body-enclosing outer wall and an inner wall enclosed by the shell body, which walls are mutually sealingly connected at the top thereof so as to form an annular compartment which is open at the bottom and into which a top part of the shell body projects.          The inner wall has a bottom part which encloses a central space defined by the inner wall.  Ballast tanks are provided for adjusting the displacement of the upper member-in the medium within the shell body.

Abstract: ABSTRACT OF THE INVENTION   A machine or process for comparing fingerprints based on the correspondence between fingerpring minutiae.     The pattern of minutiae in an unknown or search fingerprint is rotated and translated to obtain approximate registration with the pattern of minutiae in a known on file fingerprint.  Following rotation and translation, only those search and file fingerprints that exhibit a sufficient number of mating minutiae between the fingerprints are compared further.     For each pair of mating search and file minutiae, the neighboring mating minutiae are compared and an individual minutia "match score" is determined based on the degree of correspondence between the other mating pairs of minutiae within a specified neighborhood of the individual pair of mating search and file minutiae.  The individual "match scores" for each of the mating minutiae are summed to yield a total score that is indicative of the correspondence between the search and the file finger-prints.

Abstract: ABSTRACT In a method for the dewatering of naturally moist, coarse lump peat or of a similar material, the material is continuously fractured into particles to approximately 2-3 cm diameter and is dispersed onto a lower screen belt. With the leading in of a provided upper screen belt the material is conveyed between the two screen belts through a preliminary dewatering zone, where at a pressure which is only given through the tension of the screen belts in a loop on at least one pair of rolls, a homogeneous filter cake is produced.  The latter is pressed in a subsequent dewatering zone of a number of pairs of nip rolls at a pressure increasing along the zone between screen belts.  Between the screen belt and the nip roll a pressure belt, equal in width to the screen belt, is carried long, consisting of an elastic watertight material, but which is designed to receive and carry away the water and to stabilize the material which is to be pressed.  After the dewatering zone, the material arrives into a high pressure zone, where it is treated between screen belts between at least one pair of press rolls at a greater pressure than on the last pair of rolls of the dewatering zone.
