Abstract: A COUPLING JOINT FOR TELESCOPING TUBULAR MEMBERS     ABSTRACT OF THE DISCLOSURE           A coupling joint for releasably coupling two telescoping tubular members in sealing relationship to one another, one of the tubular members being continuously urged inwardly relative to the other tubular member whereby a seal between said members may be maintained at all times.  The coupling joint, which may be utilized in a valve or the like with the valve body representing one of the tubular members and a bushing representing the other of the tubular members inserted into the open end of the valve body, includes the use of a resilient ring such an an O-ring for retaining the two tubular members together, the ring being positioned in opposed grooves in the telescoped portion of the tubular members.  One of the grooves on one of the tubular members is a retaining ring groove  or retaining the resilient ring during assembly of the two tubular members, and the other of the grooves on the other of the tubular members is a groove having a camming surface thereon so oriented that when the grooves are opposed to one another with the resilient ring therebetween, the compressive forces in the resilient ring seeking to expand the same exert resultant forces on the tubular members to cause said tubular members to be urged toward one another.

Abstract: ABSTRACT OF THE DISCLOSURE            An electrode for use in the electrolysis of aqueous solutions of ionizable compounds is produced by a method which comprises affixing filaments to a support fabric to form a network of filaments.  An electroconductive metal is deposted on the filaments to form metal coated filaments.  During the metal deposition, interfilament bonding takes place at contact sites between adjacent filaments.  Removing the support fabric from the metal coated filament network produces a reticulate electrode having a porosity of at least about 80 percent.  The three dimensional electrodes are highly conductive, have high internal surface area, and are mechanically strong.

Abstract: ABSTRACT         The present invention provides an improved auger for use in drilling holes in the earth.  The auger has a helical flight which is wound in a direction opposite to the normal dir-ection of rotation of the auger.  Thus an auger which is to be rotated in a clockwise manner has its flight directed in a counterclockwise manner.  As the auger enters the earth with its clockwise rotation the tailings created thereby encounter a downhole force created by the reverse flight and they are forced outwardly from the auger so that they enter natural fissures or porous zones of the earth along the wall of the hole.          No tailings reach the surface of the earch to create environmen-tal problems.  When water is used, as in drilling deeper as for seismic exploration, the water and tailings enter the wall of the hole and create a form of cement which prevents wall collapse.  Drilling is faster and more economical, with fewer breakdowns, than with conventional augers.

Abstract: ABSTRACT OF THE DISCLOSURE           A carbamic acid ester corresponding to the formula R1-NH-CO-OR2 is thermally cleaved to form iso-cyanate R1-NCO and alcohol R2-OH fractions.  This cleavage is accomplished by boiling the carbamic acid ester, condensing the vapor given off in a first frac-tionation column, and condensing the vapor from the first fractionation column in a second fractionation column.  The boiling of the carbamic acid ester is carried out in a manner such that the average dwell time in the reaction vessel is from 1 to 20 hours, the temperature is from 160 to 260°C and the pressure is from 0.001 to 2 bar.  The isocyanate fraction obtained by this cleavage process may be used as a starting material for a transurethanation reaction in which a lower boiling isocyante R3-NCO is pro-duced.  The radicals R1, R2, and R3 are defined herein.

Abstract: Abstract of the Disclosure Method and apparatus for concurrently and interactively displaying a selected plurality of measurable properties of geophysical data to empirically derive the best combined pre-sentation of the selected attribute properties for interpretation.          The technique of the present invention allows the interpreter to more easily comprehend simultaneous variation of several geophysical data attributes and to relate the effects to a specific end result for the geophysical indicators of interest.    In accordance with the method, the one or more geophysical attri-bute variables are quantified and then rasterized so that the data is represented as a gridded variable area display wherein color intensity of the grid units is some function of the instan-taneous variable.  The resulting data is then loaded into digital refresh memory of an image processing computer whereupon it is interactively mixed for analysis in accordance with operator selected colors and color intensity weighting.

The circuit (5) converts an input signal (ui) between the bases of the two transistors (51,52) into two opposite phase output currents, which are distributed by the first (1) and third (3) current distri-bution circuits. The interconnected emitters of the second (2) and fourth current distribution circuits are connected to the outputs of a second converter circuit (6) comprising two transistors (61,62) whose emitters are coupled together by means of a second impedance element (60).  The outputs of the first () and second (2) current distribution cir-cuits on which output currents appear which are influenced in an opposed manner by the control voltage (ust) are con-nected to a first resistor (8) and the outputs of the third (3) and fourth (4) current distribution circuits on which output currents appear which are influenced in an opposed manner by the control voltage (ust) are connected to a second resistor (9).  The voltages across the first (8) and second (9) resistors are applied to a differential ampli-fier (7), whose output voltage (uo) is applied to the in-puts of the second converter circuit (6).  The output volt-age (uo) also forms the output voltage of the gain control arrangement.  This output voltage (uo) is related to the control voltage (ust) in accordance with an exponential function over a wide range of control voltages without show-ing even harmonics.
