摘要： A calender comprises a vertical stack of interlinked rollers driven individually by regulated electric motors. The regulation process acts on the distribution of the delivered power to the individual rollers such that the forces acting on the rollers in the horizontal direction and measured in the roller bearings are minimized allowing slimmer rollers to be used.

摘要： Extended-nip roll press for dewatering a material web comprises a rotating mating roll and an extended-nip press roll. The extended-nip press roll has a stationary support and a flexible roll cover which rotates about the support. A press shoe is arranged on the support, and the roll cover has end sections which are clamped firmly on rotatable end walls on the support. End wall clamping rings respond to a first actuating device and clamp a resilient spreader ring radially against an outer ring that can be connected firmly to the end walls. A sealing ring is arranged on each end wall adjacent the clamping ring and can be deformed radially against the outer ring by means of a second actuating device.

摘要： The calender disclosed comprises a vertical stack of linked rolls, which are driven individually by controlled electric motors. The control acts on the distribution of the supplied power to the individual rolls in such a way that the forces which act on the rolls in the horizontal direction, and are measured in the roll bearings, are minimized. This allows the use of slimmer rolls.

摘要： A roller has a rotary hollow cylinder through which extends a non-rotary crosshead. The hollow cylinder is supported on the crosshead by two opposite rows of hydrostatic supporting elements. When the roller is operated at particularly low linear pressures in the roll gap, a uniform linear force over the whole width of the paper web is exerted in the row of supporting elements opposite to the roll gap, causing an increase in the hydraulic pressures required in the row of supporting elements that faces the roll gap, until said pressures reach a range in which perfect operation of the supporting elements is ensured.

摘要： An improved roller apparatus for treating material webs, in which energy requirements are reduced by decreasing losses caused by fluid turbulence. The apparatus includes a cylindrical, hollow roll, supported on a shaft by hydraulic fluid under pressure. Longitudinal seals subdivide the area between the roll and the shaft into chambers. As the roll rotates, a fluid flow is established within the cylinder, in the direction of rotation. Rather than allow the fluid to establish a turbulent return flow path within each chamber, a return path isolated from the rotational flow is provided. One such return path is a group of channels formed transversely through the shaft, or alternately, recesses can be formed circumferentially in the shaft, covered to separate the return flow from the rotational flow.

摘要： When distinguishing between fat and water in acquired MR data, a modified Dixon technique includes acquiring first and second signals Ii and I2, calculating the first and second components B and S of the signals Iχ and I2, where one of the first and second components corresponds to fat and the other corresponds to water, deriving two differential phase error candidates from them, and selecting a phase error candidate based on the assumption of smoothness of the disturbing field inhomogeneity. The exact determination of the absolute values of the water and fat components is then made by solving three signal equations for two variables that respectively correspond to water and fat, and is performed using for example a least square minimization with a Newton method.

摘要： The invention relates to a projection values processing apparatus (1) for processing acquired projection values. A first image is reconstructed from acquired projection values under consideration of a reconstruction assumption by a reconstruction unit (13). A simulated projection values determining unit (14) determines simulated projection values by simulating a projection through the reconstructed first image under consideration of the reconstruction assumption, and inconsistency values are determined for the acquired projection values by an inconsistency determining unit (15), wherein an inconsistency value is indicative of a degree of inconsistency of a respective acquired projection value with the reconstruction assumption, by comparing the acquired projection values and the simulated projection values. The inconsistency values can be used for different purposes, for example, improving the quality of a reconstructed image or indicating image elements being affected by an inconsistency between reconstruction assumption and acquired projection values.
