Abstract: This invention relates to a wave energy conversion apparatus comprising at least a base, a reciprocating panel, supporting legs and a pivot shaft for the reciprocating panel, and a power-take-off machinery equipped with a generator comprising a rotor, in which apparatus the panel is hinged at its lower edge onto the stationary supporting legs to make a reciprocating motion in response to kinetic energy of waves or tidal currents. The apparatus comprises an actuating mechanism to convert the power of the circumferential speed of the reciprocating panel at a distance point being situated at the area of the upper half of the panel mechanically to a rotational movement of the rotor of the generator of the power-take-off machinery.

Abstract: An assembly for guiding different types of inspection and machining apparatuses around permanently installed pipes and shafts in power plants and similar locations. Such assemblies are used for guiding equipment employed in the inspection and machining of elongated objects with a circular cross section around said objects. According to the invention the assembly is mounted around the object by a belt which is tightened between two belt pulleys so as to embrace the object. The belt pulleys are mounted on a body part to both sides of a drive motor that drives both belt pulleys synchronously via gear wheels. The mounting of the assembly on the object to be inspected is extremely rapid.
