Abstract: Case 4307 CHEMICAL PROCESS                 Abstract of the Disclosure It is disclosed that the production and recovery of water soluble carboxymethyloxy succinic acid salt from zinc or alkaline earth metal carboxymethyloxy succinic acid salt is enhanced by adding the zinc  or alkaline earth metal salt to a carbonate which forms therewith a water soluble carboxy-methyloxy  succinic acid salt.  The treating process, performed in an aqueous system, produces a zinc or alkaline earth metal carbonate precipitate which is readily and quickly filtered providing a significant improvement in filterability over that experienced when the starting carbonate is added to the alkaline earth metal carboxymethyloxy succinate.  Preferably the addition is progressive; that is, the zinc or alkaline earth metal carboxymethyloxy succinate is added to the carbonate gradually so that for the most part the carbonate is present in excess over the other reactant.

Abstract: ABSTRACT         A selectively rotatable cylinder for a lock has a cylinder housing with a bore extending along an axis.  A cylinder plug having a keyway wherein is rotatable in the bore about the axis.  The plug is connected to a driving means for actuating any connected lock mechanism.  In the cylinder body and cylinder plug are pin tumblers adapted to be positioned by a key in the keyway.  An upper tumbler pin in the cylinder body is spring-pressed toward the keyway.  A portion of the cylinder plug in the transverse plane of the upper tumbler pin is cut away to provide a substantially chordal cam surface or ramp extending from the periphery of the plug to a radially inward intersection with the keyway.  The upper tumbler pin follows the ramp and moves toward the axis as the plug is turned by a key in the keyway.  The side of the key encounters the lowered upper tumbler pin after a predetermined amount of rotation about the axis, thus preventing further rotation of the cylinder plug.  A special key with a cut-out slot when located in the keyway and turned passes or clears the lowered upper tumbler pin and affords additional plug rotation about the axis.

Abstract: METHOD AND APPARATUS FOR MEASURING IN  SITU DENSITY AND FABRIC OF SOILS     Abstract of the Disclosure A method and implementing apparatus for measuring in situ the electrical capacitance and resistance of soils and determining therefrom the density and fabric thereof. The apparatus includes a self-contained probe adapted to be driven into the soil to be measured.  The probe has a soil sensor element and a measuring circuit such as a capacitance and resistance bridge.  The measuring circuit employs radio-frequency current to enable direct measurement at the probe of the resistance and capacitance of the soil sample and of the pore liquid.  A remote indicator and control unit in communi-cation with the probe is provided with indicators such as meters or displays which provide direct readout of measured resistance and capacitance, and which may also enable the bridge in the probe to become balanced.  Alternatively, the probe may include a computer for automatically balancing the bridge and calculating critical soil properties.  The apparatus can automatically register such engineering properties as density, porosity, friction angle, elastic and secant modulus, coefficient of dynamic settlement, stress ratio required to cause lique-faction, and permeability coefficient.  The probe and measuring equipment can, alternatively, be manually balanced and the engineering properties and related properties can be hand calculated.  The concept outlined and apparatus can be extended or modified for a wide variety of other uses also.
