Abstract: A device for slowing down and disintegrating a plug of liquid plunging forward in a duct includes a container having a bottom and an opposite inlet, which is connectable to the duct and through which the plug of liquid can be directed into a central, axial trajectory in the container. Inside the container is an inner tube, open towards the bottom, which separates an inner hollow space from an outer, cross-section-wise ring-shaped hollow space, a distributor body being arranged in the trajectory of the entering plug of liquid for splitting and disintegrating the plug of liquid as well as throwing out the disintegrated constituent parts of liquid in the direction outwards from the center. The bottom includes a concavely curved guide surface for diverting the liquid from one of the hollow spaces to the other to reverse the direction of motion of the liquid. A corresponding method is also provided.

Abstract: A method for storing or streaming images, wherein the images can be further processed after the storing or during the streaming includes the steps of choosing a span of the initially captured data, this span being adapted to be shown as an image to a user storing or streaming this chosen span of the data as an image in a file format or onto a stream to which additional information can be attached and which file format or steam could be processed by at least one standard application storing or streaming all or a part of the initially captured data as additional information to this file format or stream, and storing or streaming parameters needed for the processing of the image as further additional information to the file or stream.

Abstract: An IR camera comprises an IR Focal Plane Array having a number of detector elements as sensor devices, an optical system focusing an object onto the Focal Plane Array, and a signal processing system connected to the Focal Plane Array. The camera also has a modular structure comprising a camera housing provided with the Focal Plane Array and the signal processing system, an absorbent/emitting shielding device connected to the camera housing, and an optical focusing system removably mounted to the shielding device.

Abstract: A device for the separation of solid objects (9) from fluid flowing in a conduit tube (2) includes a housing that includes a tubular outer wall (3) and a tubular inner wall (4). Between these is delimited a collecting space (8). Concentrically relative to the inner wall (4) is provided a rotation-symmetrical central body (12) which at opposing ends cooperates with flow converting devices (15, 16), which transform incoming flow to a rotative motion and outgoing flow to an axial motion. In the inner wall (4) are recessed tangentially separated holes (20) of elongated shape, through which the scrap objects may pass and be collected in a collecting space (8). In the collecting space (8) a calm flow operation is obtained which guarantees that collected scrap objects are not carried away and returned to the main fluid flow through the separation device.

Abstract: The invention relates to a steam blowing tube for nuclear power plants of the kind which has a lower end immersed in a water pool, the purpose of tube being to permit, if required, the blow down of steam into the water of the pool with the purpose of condensing the same so as to counteract the build-up of damaging steam overpressure in the containment of the reactor. A number of through holes are recessed in the wall (11) of the individual blow down tube (10) which each one is delimited by upper and lower edges (13, 14) of which at least one constitutes part of a portion (15) bent in relation to the tube wall (14). The lower hole edge (14) forms a steam flow cutting edge which, when the steam rushes down through the tube, divides a part flow from the main steam flow and brings said part flow out into the surrounding water of the pool before the main flow reaches the bottom opening (12) of the tube.

Abstract: There is disclosed a bridge or like pillar (1) erected in a moving body of water in which the water may periodically flow in strata in one as well as the other of two opposite main flow directions. The pillar is provided with a flow compensation device including a motor-driven stream generator (9) which functions to set part of the water in motion thus compensating for the flow resistance exerted by the pillar in the water body.

Abstract: A device for filtering water to at least one emergency cooling system in a nuclear power plant of the type comprising a reactor arranged in a containment which substantially consists of an upright, suitably cylindrical container whose bottom part forms a pool for collecting water formed by condensation of steam present in the containment, the condensation pool including a number of back-flushable containers filter water which is taken from the pool and, if required, is supplied to nozzles in the emergency cooling system in order to cool the reactor core in the event of an inadmissible temperature rise therein, each strainer having a shape of a housing with at least one, suitably cylindrical, apertured strainer wall through which the water can flow from the outside and into the housing, and being connected, by a first conduit passing through the container wall, to a suction pump disposed outside the container wall, as well as connected to a secondary conduit for supplying wash water to the interior of the hous

Abstract: A strainer device for filtering water to an emergency cooling system in a nuclear power plant includes a housing or tube having a perforated or apertured strainer wall through which water may flow from the outside and into the interior of the housing in connection with the regular filtration of water taken in. A water-receiving accumulator tank is connected to the cavity of the strainer housing and a source of pressurized gas is connected to the tank in order, if required, to feed pressurized gas into the tank so as to momentarily force water out therefrom and into the cavity of the strainer housing while backflushing the same.

Abstract: A device for mixing two fluids having different temperatures comprises a connecting branch (6) extending into a main pipe (1) from a secondary pipe (2), said connecting branch having at its end positioned in the main pipe a distribution casing (7) with double annular walls, of which an inner wall (9) defines a channel (10) extending axially and centrally in the main pipe (1), and having apertures which allow a fluid (B) to be conducted into and mixed with the fluid (A) passing through the main pipe. The apertures consist of a plurality of small apertures (11) which are formed in the inner wall (9) of the distribution casing (7) and provide intermixing of the two fluids directly in the channel (10) positioned centrally in the main pipe (1).

Abstract: A strainer device for filtering water to an emergency cooling system in a nuclear power plant containment area having a lower part which forms a pool in which the strainer device is mounted. The device includes a strainer housing with separate strainer walls between which a flexible strainer means operates. The unit is arranged to be kept in a first position when water is drawn through one of the strainer walls, in which position it interrupts the connection between the other strainer wall and a suction conduit. By inherent flexibility, a shield means is automatically switched over to a second position which opens the connection between the second strainer wall and the suction conduit, as soon as the first strainer wall is clogged by impurities to such an extent that a low-pressure arises in the space between the first strainer wall and the shield means unit, which low-pressure brings about the switching-over by its suction effect.
