摘要： In accordance with the present invention, an impulse generator of high portability is provided using a pair of guillotinized, separately activated hammer/anvil sub-assemblies. Since each sub-assembly is horizontal positioned, say in contact with the earth from a position below the wheel of an exploration truck, the equivalent of the "flying blade" of a guillotine, i.e., a weighted hammer element, must be provided with horizontal movement. This is done by tensioning a plurality of springs attached between the hammer element and a rectangular main frame.During cocking and release of the hammer, the explorationist is provided with a series of visual signals in the form of deactivated and activated panel lights. These signals are automatically provided by controller means of the present invention. Release of the cocked hammer, however, is operator controlled for safety reasons say by activation of a latching means attached to the main frame of the assembly.

摘要： A pressure-controlled valve comprising an elastic-walled conductor, such as a tube, with a flow-obstructing body within the conductor. Fluid flow through the conductor is controlled by expanding the elastic wall away from the flow-obstructing body to provide fluid flow paths and by contracting the elastic-wall of the conductor toward the body to close the flow paths. Expansion and contraction of the elastic-wall of the conductor is in response to the differential pressure between the inside and the outside of the conductor.
