Abstract: To facilitate the construction of a very high structural member for use in a body of water such as at an offshore location with the structural member extending from the floor of the body of water to above its surface, tensioning members are inserted into relatively narrow tensioning ducts accessible only from the top of the structural member. The tensioning members, such as steel rods, steel wires, or steel wire strands, are provided with members for effecting a positive locking engagement in a hardenable material forming an anchored length of the tension member at the lower end of the tensioning ducts. Initially, the tension members are lowered into the lower ends of the ducts and then are grouted in the ducts by a hardenable material. After the hardenable material has set over an anchored length, the tension members are tensioned within the ducts. Next, the tensioned length of the tension members in the ducts is grouted with a hardenable material to provide a composite action with the structural member.

Abstract: A microphone arrangement comprising at least two individual microphones arranged closely next to each other, whose individual microphones depending on the recording angle desired for the sound recording are a pressure- and/or a pressure gradient receiver and/or a directional line microphone, is characterized by the wind pressure being continuously measured during the sound recording by means of a microphone (Mw) with downstream switched electronic circuit (5, 11, 12) and depending on the respectively prevailing wind pressure always that microphone (M1, M2, Mn) remains switched to the amplifier 9 assigned to it by an instantaneously controlled switch (6, 7, 8), which in its conversion principle, frequency course and its directional effect is least sensitive to wind noises for the prevailing wind intensity.

Abstract: An explosive powder charge operated fastening element setting tool includes an interceptor (14) for intercepting or cushioning a driving piston (8) in the event excess energy is supplied to the piston in driving a fastening element into a receiving material. The driving piston (8) has a shoulder (12a) displaceable when excess energy is present into the axially extending region of a deformable stopper (27) in contact with a bolt guide (4). If the interceptor (14) for the driving piston (8) does not afford an adequate braking, the shoulder (12a) runs up against the stopper (27) and the stopper is deformed and tightly clamps or jams the driving piston (8) so that it can not be freely displaced. When such jamming action takes place, the tool operator is signaled that a buffer (23) between the interceptor and the bolt guide and possibly the stopper (27) need to be replaced.
