Abstract: In TV receivers line flicker occurs at horizontal transition or separation lines between a light and a dark picture area as reproduced in successive half pictures in respective positions mutually vertically displaced by one line width, whereby the separation line is jumping up and down. This is counteracted by a detector (18) continually detecting the distribution of the intensity of the video signal in an area vertically above and underneath the picture spot and producing a correction signal whenever a significant difference of intensity is detected. This signal is fed to or generated in a control unit (20) which affects the vertical deflector system (6) in a manner such that in one or both of the half pictures the line under reproduction will be displaced to such an extent that the said separation line in both of the half pictures will be reproduced in entirely or approximately the same geometrical height position on the screen, whereby the said jumping is eliminated or reduced.

Abstract: The winding mandrel comprises a cylindrical winding drum or body which has two circumferential web members on its inner side. Each web member lies substantially in a plane which lies outside the center of gravity of the winding mandrel together with the coil or wound package. The winding mandrel bears upon two driven and tandemly arranged support wheels with one of its web members. A support roll is arranged beneath these support wheels. A lateral support surface of the web member bears against this support roll. The support wheels are constructed as friction drive wheels and, in addition to supporting the winding mandrel, serve to drive the winding mandrel. Due to the overturning or tipping moment induced by the eccentricity of the bearing points of the winding mandrel upon the support wheels in relation to the center of gravity, the winding mandrel is pressed against the support roll. This has the effect that the winding mandrel maintains the desired position during its rotation. This position is partly determined by the support roll constituting a contact roll arranged to be immovable in the direction of the longitudinal axis of the winding mandrel.

Abstract: A vascular graft is used to supply blood to one or more coronary artery branches. The vascular graft has an elongated U-shaped tubular body providing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver. One or more openings in the body allow blood to flow into the coronary artery branches. The flow and pressure of the blood in the passage is controlled by a restriction providing a Venturi passage located remote from the inlet end of the tubular body. The restriction is reinforced with an annular sleeve to maintain a desired cross sectional area and length of the Venturi passage. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the body passage and provides a continual supply of blood for the coronary artery branches.
