Abstract: ABSTRACT OF THE DISCLOSURE In making a lead electrode for a lead-acid accumulator or the like, a supporting body of titanium is pickled in a boiling solution of oxalic acid and then adsorptively coated with a titanium (IV) layer in a treatment bath.  This treatment is followed by the anodic coating of the titanium body with PbO2 in an electrolyte containing the lens of lead (II), in the presence of a lead (II) nitrate or a lead (II) salt of an amido. imido, nitride or fluoro sulfate or phosphate.  The treatment bath may be an aqueous solution of an organic titanium salt, the pickling solution, or the electrolyte.  If the pickling solution is used for this purpose, the titanium body is anodically connected or the solution is oxygenated.  If the electrolyte is utilized, Ti(IV) ions are introduced into that liquid in which the titanium body is immersed for an extended period before closure of the anodizing circuit.

Abstract: CONTROLLED TORQUE AIR MOTOR            Abstract of the Disclosure A power operated wrench having a clutch means dis-posed to effect relative rotation between the drive means and the output spindle.  The clutch means cooperates with the gear reduction system to allow the drive means to continue rotating thereby allowing repeated application of the maximum torque output of the drive means.  The clutch means further effects a reduction of the system inertia which must be absorbed by a fastener after high speed run down and thereby prevents overtorque.

Abstract: Abstract of the Disclosure:  A method of removing a catalyst-poisoning contaminant, such as arsenic or selenium, from a hydrocarbonaceous fluid, such as a synthetic crude, characterized by a multi-step process as follows.  First, at least two guard beds are prepared from a plurality of particles of material that is either iron, cobalt, nickel, oxides, or sulfides of these metals or mixtures thereof.  Next, the syn-thetic crude oil is admixed with hydrogen at a superatmospheric pressure of at least 500 pounds per square inch gauge (psig) and flowed past the particles serially through the guard beds, contacting the particles in the first bed at a temperature in the range of from about 300 to about 550°F and contacting the particles in the second and subsequent guard beds at a tempera-ture greater than said first bed and greater than 550 and up to about 850°F.  Some reduction in the concentration of the con-taminant is effected in the first, low temperature guard bed.          A generalized distribution of the contaminant over a major part of the low temperature guard bed is effected, instead of a high concentration in the first part of the bed to be contacted.          Surprisingly, the low temperature bed effects a more general deposition of the contaminant on the second, high temperature bed, and  prevents flow-blocking concentration in the first part of the high temperature guard bed.  Also disclosed are specific process details, including a preferred type of material.

Abstract: Abstract of the Disclosure A sealing system for a rotary rock bit acts as a barrier to the pulverized cuttings and other materials in the borehole and prevents the materials from entering the bearing area through the cone mouth opening of the cone cutter.  The bearing rollers are substantially captured in a groove machined into the cone cutter.  This allows a seal unit to be located at a substantial distance from the hostile drilling environment and-increases seal life.  The shirttail portion of the bit body and the base  of the cone cutter cooperate to retard materials in the borehole from contacting the seal unit.  The sealing system is provided without reducing the bearing capacity of the bit's bearing system.

Abstract: A RECURSIVE DETECTOR-OSCILLATOR CIRCUIT Abstract of the Disclosure Disclosed is a recursive circuit capable of serving as a signal detector or as a signal generator. The circuit comprises a shift register capable of storing multilevel signals, and a feedback network responsive to an input signal and to the output signals of selected stages of the shift register. In the feedback network, the output signals of the selected stages are each multipled by prechosen integers, and then added with the input signal to form a sum signal which is applied to the first stage of the shift register. The sum signal is developed by nonmodulo addition, and the multiplying integers are prechosen to cause the characteristic function of the circuit to be a cyclotomic polynomial. Detection of the presence in the input signal of a signal having a chosen frequency is accomplished by the sum signal excluding a predetermined threshold level. Signal generation is accomplished by presetting the register to a nonzero state and allowing the output signal to develop in accordance with the characteristic function of the circuit.

Abstract: ADJUSTABLE ROW SPACING FORAGE HEAD               ABSTRACT OF THE DISCLOSURE            Individual row units on the harvester, each including a crop transfer trough, cutting means at the forward end of the trough, and cooperating conveyors along the trough, are inda-pendently swingable relative to one another for changing the space between the troughs at their forward ends in accordance with the row spacing encountered in a particular field. The spacing at the rear ends of the troughs remains unchanged in all positions of swingable movement of the units so that the dimensions of the discharge zone into which the crops are de-livered by the units may remain constant.  Individual sets of disc cutters serve as the cutting means for the row units and are driven by the same mechanism that operates the conveyors, eliminating any reciprocating structure across the front of the units which would otherwise inhibit adjustable swinging thereof.  Intermeshing gears of the drive walk around one another without disengagement during adjustable swinging of the units, and a hood between the units expands and contracts during swinging to present a continuous closed surface between the units regardless of their relative angular positions.

Abstract: APPLICATION FOR LETTERS PATENT FOR              A PRESS           ABSTRACT OF THE DISCLOSURE         The invention is directed to a press having a crown member and a base member with support and tiedown means for maintaining the crown member at an operative predetermined work station relative to the base member, and operative press ram means operating between the crown and base means in direct or offset loading position on a workpiece, characterized in that the support and tiedown means comprises hollow columns characterized by greater resistance to the bending forces induced by offset loading than support and tiedown means comprised of solid columns composed of the same kind and amount of material as the hollow columns.  These columns furthermore may comprise pressure fluid-actuated cylinders having cooperating pistons and piston rods.  By rigidly affixing the base of these cylinders to one of the crown and base members and the free ends of the piston rods to the other, actuation of the piston rods to the outward throw or extended position moves the crown member away from the base member, and actuation to the inward throw or retracted position causes it to move toward the base member and, when so fully actuated, holds the crown member immovably at the predetermined work station.  The hollow cylinders should optimally have a relatively large length to breadth ratio and a relatively large bore.
