Abstract: ABSTRACT         Producing a fracture network in deep rock, e.g., in an ore body, by detonating explosive charges sequentially in separate cavities therein, the detonations producing a cluster of overlapping fracture zones and each detonation occurring after liquid has entered the fracture zones pro-duced by previous adjacent detonations.  High permeability is maintained in an explosively fractured segment of rock by flushing the fractured rock with liquid, i.e., by sweep-ing liquid through the fracture zones with high-pressure gas, between sequential detonations therein so as to entrain and remove fines therefrom.  Ore bodies prepared by the blast/flush process with the blasting carried out in sub-stantially vertical, optionally chambered, drilled shot holes can be leached in situ via a number of holes previously used as injection holes in the flushing procedure and a number of holes which are preserved upper portions of the shot holes used in the detonation process.  In the leaching of ore, fines are removed from fractures therein by inter-mittent or continuous flushing of the ore with lixiviant and high-pressure gas, e.g., air, using in the case of the in situ leaching of an explosively fractured ore body, a lateral and upward flow of lixiviant from zones that have been less severely, to others that have been most severely, worked by multiple detonations in the ore body.

Abstract: TITLE: TILT MOUNT FOR MOUNTING AN OUTBOARD MOTOR        ON THE SIDE OF A CANOE             ABSTRACT OF THE DISCLOSURE      A tilt mount for mounting an outboard motor on the side of a canoe including a U-shaped bracket formed of a flange which terminates at its upper end in a right angularly disposed cross bar portion.  The bar portion terminates in a right angularly disposed base portion parallely disposed to and spaced from the flange which forms a U-shaped member adapted to fit over the gunwale of a canoe.  A pair of clamp members are mounted on the flange adapted to engage a gunwale between the clamps and the base portion.  A motor mount mem-ber is pivotally mounted on the cross bar adapted to pivot in either direction from the vertical and a stop member is connected to and extends from the lower end of the base against which the shaft of the outboard member normally abuts in a vertical position.  If the lower end of the motor shaft or propeller thereon strikes an underwater object, the motor tilts up on the mount.

Abstract: 12                  49,656 ABSTRACT OF THE DISCLOSURE    A  cryogenic  liquid  coolant  transfer  device enhances flow of a liquified gas in the inboard direction by the incorporation of a threaded insert in the rotating inlet pipe of a superconducting rotor.  The threads of the device also facilitate the reverse flow of liquid helium back into a stationary supply tube during fault condi-tions.  The objective of the insert,  during both normal and abnormal conditions, is to inhibit the flow of liquid coolant into the clearance gap that exists between rotat-ing and stationary parts of the liquified gas transfer system.

Abstract: SYSTEM FOR SORTING SEISMIC DATA IN MARINE SURVEYS.    Abstract of the Disclosure A system for sorting data from seismic surveys at sea.          The data are acquired by signal transmission/receiving by streamer cables, which streamers are equipped with position-defining instruments.  For the sorting, the area to be surveyed is subdivided into squares of defined size and position.  The data provided through the measurements is sorted, and accepted data is pro-cessed further and transferred to the individual squares in the grid pattern.  On the basis of the data, the configuration and position of the streamer is also computed, and information regarding this is displayed on a screen.  On the basis of these results, the coverage of the measurement area may be determined, and an adjustment of the vessel's steering can be carried out to allow one to obtain the best coverage of the area.  The acquired data is stored for later treatment.

Abstract: Method and apparatus for the production of liquid iron from iron oxide ABSTRACT OF THE DISCLOSURE     Method and apparatus for producing liquid iron from iron oxide, wherein the iron oxide is substantially converted to sponge iron by passing reducing gas through it in a reduction column and is then melted in a melt vessel which is in open communication with the reduction column by heat generated by reaction of oxygen-containing gas and carbonaceous material which reaction provides said reducing gas.  To improve control of the process, the oxygen-containing gas and the carbonaceous material are respectively substantially pure oxygen and coal powder which are delivered separately into the melt vessel, and the liquid iron bath in the melt vessel is stirred so as at least partly to be kept in motion.  By separate control of the oxygen and coal supplies, e.g. the level and/or direction of delivery, and by control of stirring, it is possible to control the ratio of CO and CO2 in the reducing gas and also the heat output in the melt vessel.

Abstract: ABSTRACT OF THE DISCLOSURE        OPTICAL GUIDED WAVE SIGNAL PROCESSOR FOR MATRIX-VECTOR MULTIPLICATION AND FILTERING          An array of fiber optic couplers coupling an input and an output waveguide.  The output waveguide is routed among the couplers of the array such that either backward or foward coupling exists.  With backward coupling, energy coupled into the output waveguide in a coupler of the array is guided back to the preceding coupler for coupling back into the input waveguide.  The backward coupling allows recirculations to occur between couplers to create poles and zeroes in the transfer function of the array which transfer function can be programmed or tailored somewhat to have specific characteristics.  Further, the backward coupling allows the array to be used for matrix-vector multiplication.
