Abstract: The invention pertains to a process and to a device for determining the internal condition of trees or wooden components, whereby a needle is inserted into the wood, with the aim of hereby obtaining measured results more precise than possible in the past. The solution proposed is to rotate the needle, whereby the diameter of the needle head is greater than the diameter of the needle shaft, and to measure the power consumption of the needle's drive mechanisms.

Abstract: A hawser hook for use in mooring ships to piers and similar mooring structures includes an anchoring element rigidly connected to a mooring structure, a hub mounted on the anchoring element for rotation thereabout, a hook frame mounted on the hub for pivoting along a plane normal to the mooring structure, a hook member mounted on the hook frame for pivoting between an engaging and a disengaging position, and an arresting arrangement for releasably arresting the hook in its engaging position in which a hawser or a similar mooring line may engage the hook member. The hook frame is supported on the hub in such a manner that it is suspended therefrom in a position in which it is immediately adjacent with spacing from the exposed surface when no external force is applied to the hook member while application of a force abuts the free end of the hook frame against the mooring structure.
