Abstract: ABSTRACT      According to the present invention the microporous surface of a corrodible metal body is protected against corrosive agents of the atmosphere and even such severely corrosive agents as those found in marine environments, by an impregnation in the pores of an inner protective material, preferably oil, that is substantially impervious to corrosive agents, and a covering of outer protective material, preferably resin, that is intimately bonded to the outer surface of the metal and bridges over the impregnated pores. After the impregnation, any of the inner protective material such as oil that may remain on the outer surface of the metal is selectively removed, while the inner protective material in the pores is selectively retained, whereby a secure, intimate bond of the covering to the metal is assured to protect the metal from corrosion initiating from the outside, while the inner protective material remains operatively disposed in the pores to protect the covering from corrosive undermining.

Granted: 1982-12-14
Abstract: ABSTRACT OF THE DISCLOSURE MEANS FOR ADJUSTING THE ZERO POINT         SETTING OF A METER                 Adjustment of the zero point of an instrument is achieved by rotation of a rotary element extending through the casing of the instrument.  The rotary motion of the rotary element is translated into a lateral motion of an intermediated adjustment element.  The lateral motion is a side to side motion within the instrument relative to the sides of the instrument casing.  The lateral motion of the intermediate element is in turn translated into a pivot motion of a suspension element of the instrument.  The pivoting of the suspension element causes deflection and adjusting of the indicating element of the instrument from which readings of the instrument mechanism are taken.

Abstract: ABSTRACT OF THE DISCLOSURE         An image data handling system to automatically detect and segregate from a stream of image pixels high frequency half-tone image input, continuous tone image input, low fre-quency half-tone image input, and line image input which may be present in the pixel stream.  The image pixels are first autocorrelated in accordance with a predetermined algorithm to detect if high frequency half-tone image data is present.       Data of this type found is processed by first descreening and then rescreening at a lower frequency to provide binary level pixels.  The pixel stream is analyzed for the presence of con-tinuous tone image data.  Where found, such data is processed by a template screening process to provide binary level pixels.         Remaining pixels comprising low frequency half-tone and line copy image data are thresholded to provide binary level pixels.

Abstract: ABSTRACT OF THE DISCLOSURE A water-in-air emulsion or suspension containing a dispensible material is formed by stabilization of small droplets of aqueous liquid with an interfacial barrier of very fine, hydro-phobic metal oxide particles such as silane modified silica. As the droplets are subjected to shear such as during passage through an orifice, and/or on the surface of the target, the shear forces experienced at least partially destabilize the barrier allowing the droplets to coalsesce to form particles of controlled density and increased size and eventually can be totally destabilized into an elegant cream or lotion. At least 10% of the droplets may coalesce into particles after leaving the orifice. Active ingred-ients such as antiperspirants may be added to either the aqueous liquid phase or to the powder phase as long as they do not de-stabilize the suspension. A non-pressurized system comprises a container suitable for dispensing the suspension having a compart-ment receiving the suspension, a valve means having an outlet ori-fice of a dimension adapted to impart a preselected shear and de-stabilization to the suspension and the container being adapted to enable the suspension to be propelled through the outlet orifice. A shaker-top container can also be used as a dispenser.

Abstract: ABSTRACT An improved method of producing potassium sulfate from langbeinite.  The improved method employs a "salting out" step to remove additional KCl from the mother liquor resulting from K2SO4 crystallization.  NaCl is added to the mother liquor to cause precipitation of KCl crystals. The amount of NaCl added is controlled to an amount below the saturation point for NaCl in the solution to avoid contaminating the KCl with solid NaCl.  The KCl crystals are recycled back to the K2SO4 reactors as a source of KCl. The "salting out" step eliminates an energy-intensive sub-merged combustion evaporation step from the K2SO4 recovery process and consequently reduces atmospheric emissions.          In certain material balance situations, excess end liquor resulting from the above "salting out" operation can be subjected to evaporation (solar evaporation being preferred) to recover the remaining sodium and potassium values, and to produce a concentrated magnesium chloride solution which is useful in the primary langbeinite/sylvin-ite ore refining cycle to inhibit undesirable glaserite formation.  The sodium and potassium salts obtained from evaporation can be recycled to the "salting out" step.
