Abstract: A method for cutting a hollow extruded profile section into lengths in a press flow, wherein the extruded profile section is bent upon exit from the press either simultaneously with or directly after the forming extrusion process by a force acting thereon in a transversal manner in relation to the direction of the extruding press, and a force component acts as a traction of pressure force during the forming extrusion process on the cross-sectional area of the hollow-profile walls thus arising. The bent extruded profile section is cut in the press flow by the mechanical action of a saw, whereby force exerted on the extruded profile section during cutting is compensated by a supporting device arranged adjacent to the extruded profile section, so that deformation of the bent extruded profile section is prevented.

Abstract: A cleaning apparatus (10) for a radiation source assembly (35) in a fluid treatment system is described. The cleaning apparatus comprise cleaning chamber (20) and a second chamber (25, 30) independent of the cleaning chamber which defines a fluid (typically water) buffer layer to obviate or mitigate cleaning fluid from the cleaning chamber leaking into the fluid being treated. The fluid treatment system is particularly useful for us in clean water applications in which ultraviolet radiation is used to treat the water while having the advantages of in situ cleaning of the radiation source when it becomes fouled.

Abstract: Disclosed is a method of controlling direction of radio-wave emission of a base-station transmitter which emits radio waves upon providing the radio waves with directivity in the direction of a receiver. Two antennas of a base station that are disposed at different positions transmit first and second signals that have been spread by mutually orthogonal spreading codes. A mobile station has a phase detector for receiving the first and second signals transmitted from respective ones of the antennas and obtaining a phase difference between these signals, and a direction estimator for calculating the direction of the mobile station, as seen from the base station, based upon the phase difference and for feeding back a signal representing the calculated direction from the mobile station to the base station. The transmitter of the base station transmits data toward the receiver in the calculated direction using a directional antenna.
