Abstract: A downhole valve device (1) in a drill string (14) in a petroleum well (2) and method for maintaining optimal annular fluid velocity and wellbore pressure. The device comprises a valve housing (20) connected between adjacent segments (12, 13) of the drill string. The valve housing is further provided with at least one valve (23) arranged to open and close to the flow of drilling fluid based on measured values of downhole physical parameters or on signals from the surface in order to permit the through-flow of a sufficient volume of drilling fluid necessary to adjust and maintain the annular fluid velocity of the drilling fluid and the wellbore pressure within optimal operating conditions.

Abstract: An apparatus and method for declustering cherries, including a plurality of oscillating cutting modules (36), each having a power driven shaft (40) with a plurality of circular blades (42) fixed along its length. The modules further comprise cutting ramps (46) having a tail section (48) extending under the blades, such that the clusters are suspended from their nodes at the moment of cutting. The height of tail sections (48) may be adjusted to accommodate cherry varieties having different stem lengths.

Abstract: A cutter for a tunnel boring machine is equipped with a cutter body (1) with a slanting surface (2), a cylindrical contact surface (12) and a preferably tapered threaded portion with specially designed threads (6), a clamping ring (4) with threads adapted to the cutter body's threads with a slanting surface (5) with a groove (13) with a spring (14). The cutter has an undivided (3) or divided cutter ring (with segments 3a, 3b) with a cross section with slanting lateral surfaces (7, 8) in the foot and a cylindrical contact surface (11). The diameter of the cutter ring's cylindrical contact surface (11) has a clearance tolerance relative to the diameter of the cylindrical contact surface (12) of the cutter body.

Abstract: This invention relates to a method and device for measuring the penetration of gases through a package material. More specific, it relates to a method for predicting the transmission rate of the gaseous substance through the walls of a package as a function of time from a limited number of measured concentrations of the gaseous substance within the package. Even more specific, it relates to a method and device for testing the oxygen transmission rates into packages employed for instance for food or pharmaceutical products under realistic storing conditions.

Abstract: A theft-proof bicycle comprising a frame structure consisting of three frame parts (1, 2, 3), which are connected so as to form a triangle, where the rod for the front wheel's supporting fork (4) is attached to the triangle's front corner (6), while the rear wheel's supporting fork structures are attached to the frame structure in the areas of the two other corners (7, 8) of the triangle. One of the frame parts (1) forming the triangle's front corner is designed with a holding sleeve for the rod for the front wheel's supporting fork (4). The sleeve is equipped with an extension and an aperture for passing through a locking pin. The second frame part in the area of this corner (6) is designed as a fork, one prong of which is passed on each side of the front wheel fork's rod. The supporting frame (1, 2, 3) is equipped in a corner (7) with a pivot joint in order to permit a relative movement of the supporting parts in the supporting fram's plane, between an operating or cycling position and a locked position.

Abstract: The invention relates to a system for utilization of a sinusoidal pattern of movement for propulsion or energy recovery. The system comprises a plurality of rigid hull elements, completely or partly submerged, arranged in a row, rotatably attached to one another for rotation about parallel axes of rotation across the longitudinal dimension of the row of hull elements. The system further comprises movement devices for rotating the hull elements relative to one another or movement devices for recovery of energy as a result of rotating the hull elements relative to one another.

Abstract: A skin preparation is described for protection against sunlight, containing UVA and UVB-absorbent agents, an ALA derivative and conventional supplementary substances, together with the use of the preparation.

Abstract: In a method for providing a portable flood barrier (1), flood barrier sections (2, 3, 4) comprising two parallel, spaced apart, inflatable, elongated tubes (5,6 or 5,7) which are joined by a waterproof web (8) are placed on the ground (9) with the side of one of the tubes (6 or 7) facing the flooded area (10), and the other tube (5) facing away from the flooded area (10). Both tubes (5,6 or 5,7) are inflated, and ballast water (13) is filled on the web (8), whereupon, when floodwater (14) rises, the tube (6 or 7) facing the flooded area (10) floats in the floodwater (14) and due to its buoyancy rises, thereby forming a flood barrier (1).

Abstract: The main problem area this invention is solving, is concerning reservoirs containing gas with to low well-head pressure. It is therefore desirable to increase the well-head pressure by applying downhole pumps, however this is not possible if gas is present. The core idea in this present invention, is to place a pump (5) in a “bath” of oil (14), in which oil “bath” (14) makes a gas seal (11), assuring the pump only to be imposed to oil without gas. Oil and gas from the reservoir (1) flows trough perforations (2), into a ring-space (3). This creates a significantly pressure drop of the mixture, in which creates turbulence so the gas content will separate from the oil. The pressure drop is regulated by the gas pressure valve (4).

Abstract: A method and apparatus for removing marine fouling from underwater substrates such as ships' hulls (10). The method is characterized by the steps of first subjecting marine organisms such as barnacles to an electrical field of sufficent intensity to degrade the adhesive properties of the organisms to the substrate, and thereafter physically removing said organisms with the help of rotating brushes (16) or similar abrasive removal means. The apparatus is characterized in that it includes a remotely operated submarine (12) or other suitable transport means, such as a vehicle with a magnetized caterpillar track, having a forwardly mounted electrode (14) for imparting an electric field to the organisms together with abrasive removal means (16) mounted behind the electrode for removal of the organisms. A power source (18) is provided, having one pole (20) connected to substrate (10) and a second pole connected to electrode (14).

Abstract: The invention relates to a method and a device for utilizing the heat of flue gases from combustion apparatus while simultaneously removing condensable elements from the flue gases and reducing the corrosivity of the flue gases. The method is applicable to all types of combustion apparatus where a combustion zone generates hot flue gases that are cooled in one or more heat exchangers that transfer the utilizable heat to a liquid or a gas. The method is also suitable for apparatus with considerable load fluctuations, where the fuel supply must be adjusted to the heat load. This is achieved by separating the flue gases from the heat exchangers by cooling the flue gases by means of a particulate material (2, 13) which absorbs the condensable substances, and by circulating the particulate material between the flue gases and heat exchangers (10) that transfer heat to the hot liquid or gas.

Abstract: A method and device for drawing off humidity, such as condensation fluid, from an insulation layer around apparatuses, such as pipe lines and the like. The method is characterized in that a hollow body, such as a sleeve is arranged in a passage in the insulation material, and where a number of openings in the wall portion of the hollow body or the sleeve communicates with the surroundings outside the insulation layer, whereby condensation fluid can be drawn off from the insulation layer to the surroundings via the hollow body in the form of the sleeve.
