Abstract: 735.063 GKP     S P E C I F I C A T I O N     METHOD AND APPARATUS FOR GENERATING SEISMIC IMPULSES USING HIGH PRESSURE WATER PUMP AS THE ENERGIZING SOURCE     INVENTOR:  STEPHEN V. CHELMINSKI     ABSTRACT OF THE DISCLOSURE     A powerful seismic impulse is generated in a body of water by a slug of water propelled from a seismic source by expanding pressurized gas, but the gas is retained in the source for use in subsequent firings.  The seismic energy source, which is called a "hydro gun", is recharged by pumping an incompressible liquid, preferably, water, at high pressure into the gun to compress the retained pres-surized gas.  The hydro gun includes a firing cylinder, and a piston follower in the firing cylinder divides it into a liquid-charge chamber and a gas-propulsion chamber.  The liquid-charge chamber is closed from liquid discharge ports by a shuttle which is held closed by the high pressure of gas in an operating chamber.  By pumping an incompressible liquid into the liquid-charge chamber, the follower is forced to compress the pressurized gas which is trapped in the gas-propulsion chamber.  Then, to trigger the source, the gas pressure in the operating chamber acting on a front surface of an operating piston of the shuttle is suddenly applied to the reverse surface of the operating piston.          With the shuttle thus released, the compressed pressurized gas in the gas-propulsion chamber expands against the follower to propel the liquid in the liquid-charge chamber through the liquid discharge ports into the surrounding body of water for generating a powerful seismic impulse in the water.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved hydraulic crane comprising at least one lifting cylinder to pivot the crane arm in a vertical plane relative to the crane post. A pressure--fluid line associated with the cylinder is connected to a movement-damping accumulator. In addition, a non-return valve is inserted between the cylinder and the accumulator to allow flow of pressurized liquid in one direction only away from the cylinder.          A drainage line is connected to the accumulator, said drainage line incorporating a pressure-limiting valve.          Owing to this arrangement, any added loads that arise as a result of sudden, shock-like pressures may be absorbed upon pressure relief in the accumulator without imparting jerky return movements to the crane arms.

An individual distribution line is connected to the input of each of the delay lines as well as to the output of each of the auxiliary delay lines. Digital input signal components occurring with a period T are applied to the input of the first digital delay line and each auxiliary delay line contains q of these components. These two delay lines are coupled to one another by means of a sequence reversing device which comprises a store having a capacity of q signal components. This reversing device applies, in the next control interval, q input signal components, produced in a given control interval, of length qT by the first delay line 9 in reversed order to the second delay line. Every two distribution lines which are arranged symmetrically relative to a symmetry line being connected to inputs of an adder device the output of which is connec-ted to an input of an accumulation device via a multi-plying device. A sequence of filter coefficients being applied to the multiplying device. The accumulation device now produces the sum of all products formed in a control interval.

Abstract: Abstract An in situ self-diagnostic automotive alternator battery charging system is disclosed.  Included are:  a battery; voltage regulator sensing battery voltage and generating an excitation signal; and an alternator driven by a vehicle engine provide a rectified electrical signal to charge the battery in response to the excitation signal.  Electronic circuit status detectors, variously coupled to the battery, voltage regulator and alternator, maintain a first logic state when a corresponding signal characteristic is within a predetermined range and a second logic state when the corresponding characteristic is outside the predetermined range.  Combinatorial logic means respond to a logic state sequence from the detec-tors to identify predetermined sequences of the logic states resulting in the identification of faults in the charging system.  The logic means also provides a warning to the operator of detection of a fault and a display of the location of the fault as occurring in one of the major components of the charging system.
