摘要:
In a device for conveying and positioning structural elements at a conveying track, a structural element is brought into pending state at the conveying track and the conveying track is tilted in conveying direction so that the structural element slides downwards to approach a target point. The position of the structural element is detected. The device further includes a control unit wherein the position of the structural element is detected within a predetermined range of the target point to be reached, and a time, at which the conveying track is tilted and re-tilted at a predetermined angular speed by a predetermined angle, is determined by using a calculation and control algorithm, so that the structural element is intercepted.

A device for generating a floating state of an object by sound waves includes a rigid support structure having a top surface for absorbing forces generated by the gravitation or acceleration of the levitating object and perpendicularly acting on the top surface. A thin oscillatory element is arranged in parallel to the top surface. Further provided is a vibration generator for making the thin oscillatory element vibrating and levitating above the top surface so that the object is levitating above the thin oscillatory element without contacting it.
