IPC: G01V1/147

Abstract: 1,233,026. Seismic energy generators. N. A. ANSTEY. 13 Sept., 1968, No. 43639/68. Heading H4D.  An extended seismic signal is generated by the impacts of a plurality of descending weights. The seismic source of Fig. 2 comprises a towed drum 1 containing weights 6 (e.g. steel balls) which go through a lifting and falling cycle as the drum rolls along. The lifting action is provided by irregularly spaced and dimensioned internal baffles or indentations in the drum surface, together with friction and centrifugal effects. The drum surface may be of a partially compliant material such as reinforced rubber or plastics. For land use two drums are mounted on a common axle and towed at a regulated speed such that the weights impact the drum surface at its line of contact with the ground. Acoustic coupling may be improved by apparatus which wets the ground in front of the drums, and by use of a wedge-shaped anvil arranged inside the drum and at the line of contact to be struck by the weights. The material of the weights, drum and anvil may be chosen to minimize the generation of energy outside the seismic frequency range of interest. A signal representing the waveform of the generated seismic energy, for transmission by radio to a remote recording station and also for use as a monitoring signal at the towing vehicle, is derived from (a) a magneticallyactuated detector disposed near the line of flight of the weights, (b) pressure-sensitive microphones placed near the weight impact region, (c) a continuous detector laid on the ground near the line of traverse of the source, or (d) a piezo-electric spark-generator in the anvil and actuated each time an impact occurs. Randomness of the generated seismic energy is aided by the irregularity of the drum baffles and by using different sizes or masses for the weights. Any non-randomness may be detected by computing auto-correlation functions of the generated signal so that non-random signals may be discarded in later processing. For marine use a pair of drums are supported by a towed float 32 (Fig. 6) and are rotated by an electric motor or by paddles 33. Anvil 35 is buoyant. Hydrophone 36, or a geophone in anvil 35, provides a signal representing the generated seismic energy. If the drums are sealed the source may be used totally immersed. In a modification, four or more drums may be supported by lifting apparatus from the sides of a ship.
