Abstract: The invention relates to a process and apparatus to establish contact between liquid and vapour or gas on tray used in distillation and/or absorption columns. According to the process the liquid is accelerated upon arriving on the tray (1) perforated with holes (6) to such extent, that its velocity exceeds the velocity of the vapour or gas bubbles ascending from the liquid upon the buoyant effect. Then this accelerated flow rate is impacted with the downflow weir (9) and/or with the induction of vapour and/or gas jets having a component, oriented towards the interior of the tray (1), and a lubricant flow rate of greater layer thickness (h.sub.2) slowed down below the earlier mentioned limit velocity is produced. No bubbles separate from the accelerated flow in the accelerating zone (1) of the tray, because they are entained by the liquid. On the other hand, the vapour or gas bubbles delivered and passing through the holes of the tray (1), leave the degasifying zone 11, where the flow is turbulent.

Abstract: A method for producing workpieces with surfaces of non-circular but regular cross-sections with a working tool, wherein the workpiece is rotated about its own axis and the axis of the workpiece is rotated around an axis being eccentric to the axis of the workpiece and the two rotations being brought into a certain relationship according to the surface to be generated. According to the invention the axis of the workpiece is rotated mechanically independently from the eccentric axis and the relationship between the two rotations is established and maintained by an electrical control into which parameters of the surface to be produced are fed and with which the rotations of the axis are monitored and, in dependency of the fed-in and monitored factors, into rotational drives of the axes is interfered, respectively.
