Abstract: A device for stabilizing of working rollers and back-up rollers of a mill stand that has, for each bending block, first hydraulic pressing units being arranged upstream of the working roller, each first hydraulic pressing unit having a piston with a piston rod and a pressure plate, the piston and the piston rod being integrated in the bending block and the pressure plate being pressable against a working roller chock, and for each stand column, at least one second hydraulic pressing unit, the second hydraulic pressing unit being arranged downstream of the back-up roller and having a piston with a piston rod and a pressure plate, the piston and the piston rod being integrated in the stand column and the pressure plate being pressable against the back-up roller chock, and a first hydraulic pressing unit containing a first oscillation absorber.

Abstract: The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.

Abstract: The present invention relates to an integrated electronic device for digital signal processing, which includes a reference clock input for receiving a reference clock, a phase locked loop (PLL), a phase interpolator (PI) coupled to the phase locked loop (PLL) for shifting a phase of an output clock signal of the PLL in a stepwise manner so as to generate a shifted output clock signal (PHI_out), a logic stage for determining the state of the reference clock signal (REF_CLK) multiple times during an edge of the shifted output clock for each phase shift, a storing means for storing information whether or not the determined state of the reference clock signal (REF_CLK) is stable for a phase of the shifted output clock signal (PHI_out), and an interface configured to read out the stored information for determining the jitter of the shifted output clock signal (PHI_OUT).

Abstract: The invention relates to an integrated electronic device for digital signal processing, which includes a phase locked loop for generating an output clock signal based on a reference clock input signal, multiple outputs for providing multiple representatives of the output clock signal, a stage for generating a phase shifted output clock signal having multiple phases spanning one clock period of the output clock signal, a register having multiple units each coupled by a data input to a representative of the output clock signal, and to the phase shifted output clock signal for storing single bit values in response to an edge of the shifted output clock signal, wherein the stage for generating the phase shifted output clock is controlled to selectively shift the phase of the output clock and circuitry for reading out the stored single bit values from the register is provided in order to determine the output skew of the output clock signals based on the read out single bit value.

Abstract: The fore and aft sections of a folding boat frame each have a post located in the longitudinal median plane of the section, and two sets of elongated stringers extending away from the post on respective sides of the median plane. Each stringer has a first portion attached to the frame and a second portion hinged to the first for folding the two portions on each other. Each set includes a bottom stringer having a major longitudinal face. The first stringer portions are pivotally connected to a rib frame which may be folded about an axis in the median plane toward and away from the plane. The bottom stringers are fastened to the rib frame in such a manner that they move angularly relative to each other from a position in which their major faces converge toward the median plane at an obtuse angle to a position in which the angle is much smaller and acute when the rib frame is folded.
