Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method for distinguishing full energy absorption peaks from background energy in a gamma ray prospecting system.  Photopeaks in the received energy spectrum are determined, and boundaries to the peaks are located.  The energy within the boundaries assuming a predetermined curve between the boundaries is integrated.  The filtered energy within the actual photopeak curve is also integrated, and the two integrated signals are subtracted to provide a signal representative of the net photopeak area or amplitude.  This peak area (or amplitude) is directly proportional to intensity of gamma radiation due to uranium, thorium and potassium in the ground.  This signal is displayed and continuously updated on a cathode ray tube as a function of time.  The assumption of constant Compton background energy level of the prior art is avoided and a more accurate energy spectrum obtained.

Abstract: ABSTRACT          An improved exhaust gas sensor for use in sensing the partial pressure of oxygen in the exhaust gases from an internal combustion engine.  The sensor has a titania ceramic element in which two electrodes are embedded.  The electrodes in the past have been made from pure platinum, this precious metal being required to enable the sensor electrodes to survive at temperatures up to about 900°C. in the hostile gaseous environment.  Even with the use of this platinum electrode material, electrode failures have occurred.  These now have been found to be caused by the formation of platinum carbide from the chemical reaction of the platinum electrode material with exhaust gas constituents.  Also, Pt loss has occurred from oxidation thereof and vaporization of the oxide.  It has been found that deterioriation of sensor electrodes may be prevented by forming these electrodes from an alloy consisting essen-tially of platinum and another material having a lower vapor pressure and lower surface tension than platinum.  Specifi-cally, an alloy from consisting of platinum and another metal selected from the group consisting of gold and rhodium may be used.  An alloy of platinum and gold is preferred. Annealing the titania element electrodes functions, as does the alloy formation, as a means for increasing the magnitude of the energy required for reaction of the Pt with carbon or oxygen.

Abstract: ABSTRACT OF THE DISCLOSURE A process for making a high solids content Zeolite A-alkylbenzene sulfonate detergent composition suitable for use in making spray dried deter-gent compositions includes manufacturing Zeolite A by a hydrogel, clay con-version, natural silica or equivalent process so that the Zeolite A is pres-ent in an aqueous medium containing alkali metal hydroxide in solution there-in, separating a substantial proportion of the aqueous medium from the Zeolite A so as to produce Zeolite A particles, usually in cake form, containing ex-cess alkali metal hydroxide solution on particle surfaces and occluded by such particles, and at least partially neutralizing said excess alkali metal hydroxide with a high concentration aqueous alkylbenzene sulfonic detergent acid, such as a sulfonic detergent acid resulting from oleum sulfonation or sulfur trioxide sulfonation of a linear higher alkylbenzene.  Included within the invention and preferred are processes in which, when the alkali metal hydroxide solution of the particle surfaces is neutralized with the detergent sulfonic acid, a sufficient excess of such hydroxide is present so that the detergent acid is neutralized and enough hydroxide or alkaline neutralization products are left so that the product is of a pH in the range of 7 to 11. The neutralization reaction may be carried out step-wise and such is often preferable.  Also, the products of such reactions may be spray dried directly for use as is or for addition to other detergent composition components or they may be crutched with other such components, e.g., inorganic builder and filler salts, and then spray dried.  By utilizing the present method washing or "rinsing" of the zeolite may be avoided, crutcher moisture contents before spray drying may be kept desirably low and a product of excellent physical and washing properties, which does not objectionably deposit on washed mate-rials, may be made and dried by an energy conserving process.
