Abstract: In a peer-to-peer (P2P) system, in each individual transmitting peer (10), the incoming data stream is divided logically and with regard to time into different parts, which are buffered in a volatile memory (13) and are transmitted to the receiving peers (20, 30) on different paths by means of a peer-to-peer transmission mechanism (40). In a receiving peer (20), the received parts of the subdivided data stream are buffered in a volatile memory (21) and are reassembled into a complete data stream. Further, in the receiving peer (20), the parts of the subdivided data stream, buffered by the volatile memory (21), are copied into a persistent memory (22), from where they are copied back into the volatile memory (21) at a later point in time if necessary. A fraction of the received data is excluded from persistent storing by selecting parts of the subdivided data stream.

Abstract: An electrical switch (4), in particular for electric hand tools (1), such as electric drills, hammer drills, electric screwdrivers or the like, has an actuating member (5) that can be moved from an initial position into an operating position. In the operating position, the actuation member (5) acts, for example, to switch a contact system or to adjust a potentiometer. In addition, the switch (4) has a movable actuating element (13) which, when it is moved, acts to actuate a first device the actuating element (13) is arranged in the immediate vicinity of the actuating member (5). Furthermore, in addition, a further, second device can be actuated by means of the actuating element (13).

Abstract: Apparatus and method for reducing nitrogen oxides in flue gas within a flue gas duct includes a number of distributor tubes for the injection of a reducing agent into the flue gas within the duct. Each distributor tube includes a control valve to be able to set an appropriate injection of the reducing agent to respond to different concentrations of the nitrogen oxides within the flue gas over the cross section of the flue gas duct. Each distributor tube comprises at least two parallel distributor tube segments which extend from opposite sides of the flue gas duct to the center of the flue gas duct. The two parallel distribution tube segments include a plurality of openings along the lengths thereof to supply the reducing agent generally evenly throughout their aligned portions of the cross section.

Abstract: This invention relates to a process for the manufacture of catalysts for the reduction of oxides of nitrogen from exhaust gases and in chemical air cleaning processes in which a catalytically active material containing iron ores, chromium ores and/or zeolite is placed in contact with a carrier means having a series of openings; e.g., wire mesh, expanded or perforated metal or any type of grid-like structure to form a catalytic member. The carrier means is etched with an acid etchant before forming the catalytic member or, instead, the catalytic member is etched with an acid etchant. The catalytic member is bonded by a thermal treatment; e.g., drying, tempering and/or fixing. This invention also relates to catalytic members or products produced by the process. This invention proposes the use of pressure bonding to obtain a catalytic member product which has significantly improved catalytic activity, greater mechanical strength and higher resistance to chipping.

Abstract: The invention relates to a process for the manufacture of a catalyst for the reduction of nitrogen oxides in exhaust gases. The catalyst contains a metal oxide. The catalyst is preferably used for catalytic reduction with ammonia. The process comprises screening a natural goethite iron ore to the required grain size and then treating the ore with sulfuric acid. Subsequently, the goethite iron ore is heated to a temperature which approximately equals the temperature at which it will be used in the catalytic reaction.

Abstract: In a process for the manufacture of catalyst moldings a natural raw material containing Fe.sub.2 O.sub.3, Cr.sub.2 O.sub.3 or another such catalyst component such as TiO.sub.2, NbO.sub.2, WO.sub.3, V.sub.2 O.sub.5 or MoO.sub.3 is screened to a grain size equal to or less than approximately 0.25 mm. This screened base mixture is thoroughly blended, and then preferably a concentrated sulphuric acid is added. This mixture of material is then pressed into a molding in a hydraulic press with a pressure of approximately 500 bar to produce the molding.
