Abstract: A system and a method for measuring and determining flatness of a strip (1) of rolled material. Said system is comprising a measuring roll (2) having a cylindrical central structure (41) having a number of measuring devices for force/pressure registration. Said devicesis generating measurement output signals (Upi) depending on the contact between the strip and the measuring roll (2), wherein said measurement output signal (Upi) comprises a force component signal (UFi). Said system also comprises a Flatness Determination Unit (56), said unit being arranged for calculating the flatness (&Dgr;&sgr;1) of the strip based exclusively on signals derived from measurement output signal (Upi) values generated by said measuring devices and information about the values of the width and thickness of the strip (1). The system is continuously determining the Wrap Angle (&agr;) from at least one measurement output signal (Upi) and automatically compensating for a changing Wrap Angle (&agr;).

Abstract: A method for controlling flatness of a strip (1) of rolled material rolled to a first flatness target and coiled and that is subsequently uncoiled, and a system which employs the method. Measurements of the flatness of the strip (1) during rolling are compared to both the first flatness target and to a second flatness target, a Mill Flatness Target 2. A flatness target for each of one or more subsequent processes, a Post Rolling Flatness Target (PRFT) and a measured flatness error is used to adapt a control signal for a mill stand (5) to control and regulate the flatness of subsequent production of rolled material of the same specification. The adaption may be made using different statistical techniques including fuzzy logic and neuro-fuzzy logic control methods. In the preferred embodiment, flatness measurements after decoiling are also fed forward to at least one subsequent process 12 and used to adapt control signals to regulate flatness of the current strip in the subsequent process 12.

Abstract: An active filter device provided for compensating harmonic distortion in a supply line by injecting for each harmonic (fk) to be considered a compensation current. The compensation current being determined by injecting a monitoring current on the supply line at a first (f1) and second (f2) frequency value, offset respectively on either side of the considered harmonic, and measuring response currents generated by the supply line upon injection of said monitoring currents.

Abstract: An electric coupling device for connecting, disconnecting or limiting the current in an electric circuit. The electric coupling device includes a variable resistor. This resistance is variable between a very low value corresponding to a conducting state and a very high value corresponding to a substantially insulating state. Switching between the states takes place continually and in a very short time. The invention relates to an electric circuit provided with such an electric coupling device and a method performed in accordance with the function of the electric coupling device.

Abstract: A method and system are described for improving memory access. The invention will improve memory access in systems where program code and data stored in memory have low locality. The invention builds on that the access to at least some addresses of the memory will take longer time than the access to other addresses, such as, for example, page type memory.

Abstract: An opening arrangement for packaging containers which is manufactured from a flexible packaging laminate and includes a prefabricated outlet opening which is covered by a tear-off strip or pull-tab. To facilitate pouring of the contents and permit reclosure of the packaging container, the container also displays a prefabricated pouring device surrounding the outlet opening, the pouring device being applied on the outside of the packaging container and comprising a reclosable lid. In order to ensure satisfactory function and facilitate application of the pouring device onto the packaging container, the pull-tab extends, according to the present invention, in beneath the pouring edge of the pouring device and is fixedly sealed between the pouring device and the upper side of the packaging container.

Abstract: A device for measuring birefringence in an optical data carrier has a laser light source with a polarization modifier, a beamsplitter, a polarizer, a photodetector, and a controller operatively connected to the photodetector. The laser light source illuminates various spots on the optical data carrier by means of a laser beam. The photodetector receives a reflected laser beam, converts it into an electric signal and supplies this signal to the controller, which determines a value for the birefringence in the illuminated spot on the optical data carrier. Furthermore, the device is provided with a transparent reference element with known birefringence properties, a mirror, and for directing the laser beam towards the reference element in a first calibration position; directly towards the mirror in a second calibration position; and towards the optical data carrier during non-calibration time.

Abstract: This invention relates to the use of felodipine or a pharmaceutically acceptable salt thereof for the treatment of cerebral dysfunction due to solvent exposure.

Abstract: Loops in program code are avoided by generating instructions for controlling a processor. A first template instruction is stored, and a predetermined number of instructions may be generated, wherein each generated instruction is based on the first template instruction. The processor may be alternatively supplied with the generated instructions or with instructions received from an alternative instruction source. A substitute address field may be stored, and the step of generating each instruction may include substituting the substitute address field in place of an address field in the first template instruction. The stored substitute address field may be adjusted after generating each instruction. The step substituting the substitute address field in place of an address field in the first template instruction may be performed only if a substitution control signal is asserted.

Abstract: A head which is intended to be mounted on a ladle, is provided inside with refractory material. At least one burner for liquid or gaseous fuel and oxygen gas for heating the melt in the ladle is disposed in the head. The head is provided with retainer means for the burner, by the intermediary of which the burner is axially shiftably disposed in relation to the surface of the melt bath and is rotatably disposed in relation to the vertical line of the burner to the surface of the melt bath. Depending upon the burner output, the burner is adjustable so as to emit the best possible heat transfer from the burner flame to the melt bath and, at the same time, to cause the slightest possible chemical action on the melt bath.

Abstract: A fiber-optic sensor for sensing dynamic acceleration is arranged so that the acceleration gives rise to changes in angle between at least one body and the optical axis of at least one lens of graded index type (GRIN lens). At least one optical fiber is arranged to transmit optical energy to and from one end surface of the lens. The optical energy reflected back into the fiber is dependent on the angle and essentially independent of the distance between the body and the lens, and the sensor comprises at least one photoluminescent material so that a part of the optical output signal from the sensor includes a photoluminescent signal.
