Abstract: A section mill (10) for the rolling of steel sections is disclosed. The section mill includes a universal mill stand (12) and an edger mill stand (14) for rolling a workpiece (18) in a plurality of back-and-forth passes into a steel section having a web and one or more flanges. The section mill further includes a cooling arrangement (16) for cooling the workpiece while it undergoes rolling during one or more of the passes. The cooling arrangement includes a cooling box (20) having a spray head (21) with spray openings (22) for spraying jets of pressurized cooling liquid against the workpiece. The cooling arrangement further includes an actuator (38, 34) configured to move the cooling box relative to the stand frame (58) of the universal mill stand and/or of the edger mill stand for adjusting a distance between the spray openings and the workpiece.

Abstract: The current transformer includes a magnetic circuit made of magnetic material that is intended to be placed around a primary conductor, and a secondary winding that is wound onto a portion of the magnetic circuit in order to deliver a secondary current to processing circuits. In this current transformer the magnetic circuit includes at least one device for varying the magnetization of a portion of the magnetic circuit according to the temperature in order to limit or to decrease the magnetic flux in the magnetic circuit when the temperature of the magnetic circuit increases. The protection device and the electrical circuit breaker include such a transformer.

Abstract: The present invention refers to a data management unit for supporting health control comprising a display (162), a processor (140) adapted to receive a user-selectable group of measurement values of a plurality of measurement values of a physiological parameter, for example a blood glucose level, to calculate at least one derived value (501a, 503a, 506a) from the group of measurement values and to determine for each derived value (501a, 503a, 506a) a corresponding rating value and/or a corresponding trend value, a trend indicator (164), wherein the trend indicator is adapted to indicate different trend categories on the display (162), for example an increasing trend, a steady trend and a decreasing trend, as a respective graphical picture (503d), a color indicator (166), wherein the color indicator is adapted to indicate an area (501b, 503b, 506b) with at least one of two different colors on the display (162), for example a red color and a green color, wherein the display (162) is adapted to display the at le

Abstract: Described are embodiments for allowing the negotiation of a continuous presence layout. Specifically, in embodiments, an offer is generated by a client that includes attributes for displaying continuous presence video information. The attributes include, in some embodiments, one or more window identifiers, one or more bandwidth limit identifiers, one or more group numbers, and/or one or more ranks. The offer is sent to a server which transmits an answer to the offer. Once the attributes for the continuous presence layout has been negotiated, the server uses the attributes to format video content sent to the client.
