Abstract: ACETAL GROUP-CONTAINING NON-IONIC SURFACTANTS            Abstract of the Disclosure Acetal-coupled non-ionic surfactants are easily degraded into relatively environmentally inoccuous fragments having little or no surface activity.  The fragments are sufficiently low in molecular weight to be oxidized when exposed to water and atmospheric oxygen.  Surface activity can also be destroyed by lowering the alkalinity of the medium in which the non-ionic surfactant is utilized to below pH 7.

Abstract: "MULTIPLE STAGE HYDROCARBON CONVERSION WITH GRAVITY FLOWING CATALYST PARTICLES"                            ABSTRACT          A multiple stage catalytic conversion system in which a hy-drocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones, in each of which the catalyst particles are downwardly movable via gravity flow.  At least four reaction zones are utilized, with the fresh feed and hydrogen reac-tant stream being split between the first and second reaction zones. The flow of that portion introduced into the second zone is restric-ted.  The effluent stream from the first reaction zone is also re-stricted and then combined with the effluent from the second reac-tion zone.  One portion of the combined effluent streams is intro-duced into the third reaction zone, and the remaining portion is re-stricted in flow, combined with the effluent stream from said third reaction zone, and introduced into the fourth reaction zone.  This technique decreases the mass flow to the first three zones and in-creases the pressure drop experienced within the entire conversion system, thus serving to alleviate the problems associated with the occurrence of stagnant catalyst areas as a result of catalyst parti-cles being "pinned" within a reaction zone and thus unable to assume a downward, gravity flow 'pattern.  Restriction of the second zone feed and first reaction zone effluent insures a higher pressure in the first zone.

Abstract: APPARATUS FOR TESTING THE LINEARITY               OF A FREQUENCY MODULATED OSCILLATOR by Abram Froese and Josef L. Fikart Abstract of Disclosure An APC (automatic phase control) circuit is utilized to measure the linearity of an FMO (frequency modulated oscillator).  In accordance with a common APC concept a programmable divider is connected to an output of said frequency modulatable oscillator to produce a binary output signal having a predetermined pulse repetition rate.  This signal is compared with a reference signal in a phase control comparator producing a DC control signal which is applied to the control input of said frequency modulated oscillator to maintain the average oscillator frequency constant.  This DC control voltage gives an indication of average free running frequency of the oscillator. To measure linearity, the said binary signal at the programmable divider output is also further divided and processed to produce a low frequency square waveform which is applied via a manual ON/OFF switch and a modulation amplifier to the modulation input of the said FMO.  The change in the average free running frequency of the FMO, and the corresponding change in the DC control voltage resulting from alternatively switching the low frequency waveform ON and OFF, is a measure of the FMO's linearity.  This change is amplified and a zero center meter is employed to indicate the magnitude and sign of the error, and to permit adjustment to obtain a minimum error indication.

Abstract: PRODUCTION OF PHOSPHORIC ACID AND ADDITIONAL PRODUCTS FROM PHOSPHATE ORE            Abstract Phosphate rock, including low grade phosphate ore, is treated to recover phosphoric acid and other valuable products by a series of steps including contacting phosphate ore with a weak phosphoric acid to form a suspension of at least a portion of the slimes contained in the ore so that the slimes can be separated from the ore, and separating the slimes to provide a deslimed phosphate ore.  Deslimed phosphate rock is solubilized with phosphoric acid to convert at least a portion of the calcium contained in the rock and form a solution of mono-calcium phosphate and phosphoric acid.  After removal of solids, this solution can be treated with sulfuric acid in a gypsum crystallizer to form gypsum and the phosphoric acid product wherein filterable gypsum crystals are obtained by maintaining a total SO3 content of 1.5-4 wt.% in a first crystal-lizer and neutralizing the SO3 in a second crystallizer. In other aspects of the invention, at least a portion of the phosphoric acid produced may be recycled to convert additional ore and the slime suspension may be treated to recover the weak acid recovered from the suspension.  Further, wash water from the gypsum filter may be recycled to the desliming stage, the filtrate from the deslimer may be cycled to the acidulation reactor and monocalcium phosphate may be recovered as a separate product from phosphoric acid and connected to other useful products.
