Abstract: A rolling apparatus for rolling angle profiles from rolling stock has upper and lower horizontal profile rolls rotatable about respective parallel upper and lower axes and together defining an open or closed roll gap that lies in a rolling plane perpendicular to a travel direction of the rolling stock. At least one pair of nonhorizontal edging rolls laterally compress the rolling stock and define a rolling plane extending perpendicular to the travel direction of the rolling stock. The rolling plane defined by the profile rolls and the rolling plane defined by the pair of edging rolls are not coplanar with each other. This rolling stand can do angle rolling in reversing and also continuous operating mode.

Abstract: Oblique spaced antenna method and system for measuring atmospheric wind fields within a predetermined volume, whereina pulsed beam of high frequency radar waves is transmitted in predetermined transmitting directions into the volume of the atmosphere to be investigated,parts of the radar waves which return from the volume to be investigated are received from predetermined receiving directions at a plurality of spaced receiving locations, andthe received waves are processed to derive information about the wind velocity within the volume to be investigated, to allow direct determination of parameters of the wind field, such as divergence, vorticity etc.The transmitting and receiving directions are oblique with respect to the vertical direction.
