Abstract: The present invention relates to a method for separating products from a mixture by reversed phase high performance liquid chromatography using a column packed with a stationary phase which is hydrophobic and a mobile phase, wherein the loading step, during which the products to be separated are introduced in the column, is carried out with an aqueous phase while applying an overpressure of at least about 0.3 MPa.

Abstract: Targeted messaging, for example advertisements, may be provided to a user terminal connectable to a service node in a communications network, said network comprising a library node connected to the service node and comprising messages, such as advertisements, in different formats for different access types, by the following steps: requesting the delivery of at least one message from the library node to the service node for distribution to the user terminal, while specifying in the request the access type used by the user terminal, and providing from the library node to the service node the appropriate version of the at least one message in dependence of the access type used by the user terminal. One or more parameters, such as demographic data, may be specified for how to select a message from the library node.

Abstract: A laminate for lining a passage, which is entirely or partially surrounded by walls, above or under the ground, which laminate comprises at least one layer of a reinforcement (4) of continuous fibre, a curable resin (5) and a plastic sheet or plastic film (3) which is on the inside of the laminate when the laminate is inserted into the passage (10) which shall be lined. In order to give the laminates corrosion durability and flexibility which stand on a par with the strength of the laminate so that not anyone of these parameters will determine the life length of the lining, there is arranged a mat (8) of fibres between the inner film (3) and the reinforcement (4) which mat on its side which is turned to the inner film (3) has cut fibres (13), and which together with its cut fibres can absorb resin for concentration of curable resin to the inner surface of the cured laminate.

Abstract: The present invention concerns a particulate agent for chemical and/or physical treatment of a fluid, such as a gas containing NO.sub.x and SO.sub.x, contains at least two particle types of different activity, the particle weight and/or particle size of each type lying within separate ranges. The agent may also contain catalyst particles for reducing NO.sub.x, and particles for absorbing SO.sub.x.The invention also concerns a method and a plant for treating a fluid with the inventive particulate agent.

Abstract: The invention relates to a catalyst for the reduction of nitrogen oxides and comprises oxides of transition metals on a particulate carrier material, the catalyst comprising:1) a carrier material consisting of small grains of an inorganic oxide,2) a catalytic layer thereon containing TiO.sub.2 and V.sub.2 O.sub.5, and obtained by a separate or simultaneous coating of the components on the carrier material,the catalyst particles being in the order of 10-200 .mu.m and the catalyst being intended to operate at temperatures of 150.degree.-220.degree. C.The invention also relates to a method for the preparation of the catalyst, and the use thereof for the reduction of nitrogen oxides in gases at low temperatures.

Abstract: A rotation ring barker comprises a stator and a rotor which has an opening for lengthwise feeding of a log and which is associated with a number of working tools, each of which is actuated by a spring mechanism normally striving to maintain the tool yieldingly urged against a log passing through the rotor for removing the bark from the log. If necessary, the individual tools are jointly movable in a direction outwardly from the log against the action of said spring mechanism. Positioned between the rotor and stator is a ring element which is rotatably mounted on said rotor and, during normal operation, follows the rotor. The ring element is connected, via a transmission, with the drive shaft of a pump mounted on and constantly following the rotor.
