Alternatively, marks capable of identifying the direction of the diameter line joining the hit points are set on the lead points.

Abstract: Running sole structuring for a ski, especially for a cross-country ski.The object of the invention is to provide a new profiling which combines optimum gliding and climbing characteristics. Therefore, it is the object of the invention, to provide a suitable shaping of the profiling which fully considers the special requirements under different snow conditions as well as the special loadings of the ski during the push-off and gliding phases, as well as the process of sticking and gliding friction and the transitional phases associated therewith directly.This object is solved according to the invention by the provision of exclusively straight, vertical and parallel arranged profile edges with respect to the direction of the run which are also two-dimensional in the plane of contact with the snow and are statistically arranged and, wherein the adjacent pairs of climbing edge rows lying behind each other lie on a gliding arc. It is preferred when the mean edge length (b.sub.

Abstract: A weld inspection process and an associated system for the determination and assessment of weld seams by first producing a flawless weld seam on a test specimen, making a point by point inspection of the test specimen using a pair of alternately pulsed X-ray or gamma ray sources, while generating signals which may be simultaneously displayed and stored, to form a permanent record of the test specimen weld seam, on a target plate. A point by point comparison of is made of a new, similar weld and the recorded image is instantaneously compared with the previously recorded, stored image of the flawless test weld. In the event of identical images, that point of the weld is deemed flawless, while a lack of identity indicates a flaw, in which event, the defective position is marked for subsequent repair, removal or total rejection.
