    摘要: A single television signal delay chain is interconnected with linear combination matrices for frame comb filtering and line comb filtering. Related circuits provide correction signals for controllably eliminating the frame or the line comb filtering. Detectors are provided for movement and for edges in the picture content and these detectors supply signals to a picture blending circuit for selecting the most appropriate kind of comb filtering for the current picture content. The circuits operate on a digital basis with a sampling frequency which is an integral multiple of the line scanning frequency.

    摘要: The invention concerns a rolling stand, a rolling train, and a method for rolling a stepped preprofiled metal strip. In order to guarantee that the metal strip is free of waviness in its longitudinal direction, even after individual thickness reduction of the steps, the invention proposes that the thickness reduction be carried out on a step-specific basis according to the following mathematical relationship: Δhi/hi=Δhi+1/hi+1=ε=constant, where Δhi represents the amount of the thickness reduction in the region of the i-th step, and hi represents the value of the resulting thickness of the metal strip 200 after rolling in the region of the i-th step.

    摘要: A method of preadjusting cold deforming plants, such as cold rolling trains, skin pass stands, stretcher-and-roller levelers, straightening machines, and the like, wherein the hardness of the material to be deformed is measured shortly before the cold deformation of the material and is utilized for correcting its hardening curve and the preadjustment of the cold deforming plant based on the measurement. The standard hardening curve of a material or a group of materials with corresponding standard values of hardness, yield strength, tensile strength, etc., can be corrected by an additive or multiplicative linkage with a correction member which contains at least one tensile strength determined through the measured hardness value.

    摘要: A roll, particularly a back-up roll, for rolling flat material is composed of a rotating roll shell and a unit arranged within the roll shell for influencing the bending stiffness of the roll shell. The unit for influencing the bending stiffness of the roll shell is a friction bearing in the form of a body of rotation. The body of rotation can be adjusted by rotating the body. The body of rotation is shaped in such a way that the load application surface thereof corresponding to the zone of the roll shell to which load is applied is part of the circumferential surface of a rotation-symmetrical body and the edge of this circumferential surface is shaped in such a way that along the circumference of the body of rotation the width and/or position of the load application surface vary.
