Abstract: A method and means for application of anode covering material (ACM) in an electrolysis cell for aluminium production where the cell being of Hall-Héroult type with prebaked anodes. The cell contains a cathode pot with a rectangular footprint and a superstructure with a gas collecting hood that lays onto the top of the cathode pot. A floor construction at least substantially surrounds the cell at a level below the top of the cathode pot and ventilation openings provided with grates are arranged in the floor in the close vicinity to the cell. The superstructure's hood is provided with removable lids that are removed for giving access to the cell's anodes through openings. ACM is applied via a feed tube to cover the anodes and the deposit of ACM is supported by a shuttering.

Abstract: A method of packaging safety and rescue equipment (1) as well as a package for packaging it, formed by a light-impermeable vacuum package, in whose surface an inspection window (13) is optionally provided as well as a moisture indicator (14) behind this inspection window and a drying means inside the package. The safety and rescue equipment is used in tall structures in particular, such as in windmills, on drilling platforms and in antenna masts. According to the invention, the safety and rescue equipment is protected against the weather, UV light and mechanical impacts that may occur between the line of the safety and rescue equipment and the metal parts to which the line is secured, which means that it is just necessary to inspect it in intervals of about 6 years as against normally 1 year.

Abstract: A method and system are provided for use in marine seismic data surveys to increase fold and offset without increasing streamer length or drag on the streamer boat. Generally the method comprises the use of a second source boat positioned in the steamer path and firing the second source at a time before the recording of information from the first source is finished. By positioning the second source about one streamer length in front of the closest hydrophone, the fold is increased by two for the same length streamer.

Abstract: This invention relates generally to a method and system for synchronizing the timing of events between and among vessels using a common timing reference.

Abstract: An inflated balloon (5) implanted in a patient (3) is provided with a high-frequency receiver system (7) wherein an electric current is induced upon the generation of a high-frequency, electromagnetic field outside the patient which electric current activates a puncturing device, such as an electric resistor element (11), in the balloon (5).
