Abstract:
Acid cheese curd is manufactured by acidifying milk at a temperature of 15*-30*C so that the pH is reduced to about 4.955.35 without precipitation of casein. Acidogen and proteolytic enzyme are then added to form the curd, which is then further processed to make various cheeses.
Abstract:
A composition consisting essentially of 3,3,4,4tetrachlorotetrahydrothiophene-1,1-dioxide and bis(trichloromethyl)sulfone exhibits a synergistic effect in the inhibition of growth of microorganisms in aqueous systems.
Abstract:
The preparation of the various isometric tetrachlorinated phthalonitriles involves the liquid phase chlorination of the corresponding tetrachlorinated xylylenediamine to the N,N,N'',N''octachloroxylylenediamine intermediate followed by dehydrochlorination to the desired tetrachlorophthalonitrile. Typical is the production of tetrachloroisophthalonitrile from tetrachloro-m-xylylenediamine, the product being a valuable fungicide.
Abstract:
A process for oxidizing and disinfecting waste water comprises providing an alkali metal chloride-containing waste water to a first container wherein it is agitated and macerated and electrolyzing at least a portion of said waste water to produce chlorine therein, followed by transfer to a second container wherein it is further agitated and, optionally, electrolyzed, prior to discharge. An apparatus suited to conducting the process is described.
Abstract:
Brine coming to the earth''s surface can contain substances other than salt in water; occasionally of particular interest is gas contained in the brine, especially natural gas or methane or ethane. As the brine reaches the surface of the earth, the presence of this gas is visibly apparent and gives the brine a cloudy appearance. This gas is typically well dispersed through the brine initially as very minute incipient gas bubbles that will accumulate and separate from the brine, given sufficient time. A method is herein provided for quickly and efficiently clarifying the brine by passing the cloudy brine through a filter zone providing a pressure drop across the zone of greater than about 20 p.s.i.g.
Abstract:
Coating compositions, for application to metal substrates prior to painting of the substrate, are formulated with special particulate zinc which is very finely divided, e.g., containing virtually no particles having size greater than microns. Such pre-paint compositions on metal substrates offer excellent coating adhesion to subsequently applied paint.
Abstract:
1. A PROCESS FOR THE PRODUCTION OF A CHLORINATED PHTHALONITRILE WHICH PROCESS COMPRISES: (A) INTRODUCING GASEOUS CI2 AND A MOLTEN, ATOMIZED PHTHALONITRILE INTO A FLUIDIZED BED OF ACTIVATED CARBON PARTICLES MAINTAINED AT A TEMPERATURE WITHIN THE RANGE OF 300* TO 400* C., AT LEAST THE MAJORITY OF THE CHLORINE BEING SEPARATELY INTRODUCED TO THE BOTTOM OF, AND SERVING TO FLUIDIZE, THE BED, THE PHTHALONITRILE, TO GETHER WITH ANY REMAINING CI2, BEING INTRODUCED TO THE BED ABOVE THE POINT OF INTRODUCTION OFF SAID MAJORITY OF CI2; (B) REACTING SAID CI2 AND PHTHALONITRILE THEREIN TO THE DESIRED CHLORINATED PHTHALONITRILE; (C) SEPARATING AND RECOVERING THE RESULTANT CHLORINATED PHTHALONITRILE; AND (D) RECOVERING SOLIDIFIED, PARTICULATE, CHLORINATED PHTHALONITRILE.
Abstract:
Cathodes of an electrolytic cell wherein a number of anodes and cathodes are positioned in spaced parallel relation in an electrolyte solution are maintained free of deposits which tend to form during electrolysis of the solution by contacting at least one anode of said cell prior to contacting a cathode during the introduction of electrolyte solution to the cell and contacting at least one anode with the electrolyte solution subsequent to contacting the other electrodes just prior to removal of the solution from said cell.
Abstract:
Gastropods, including the vectors of parasitic flukes that afflict man and animals, are controlled by exposing such gastropods or their eggs to an amount of a polychlorothiopheneoxide sufficient to kill the gastropods or to prevent the eggs from hatching.
Abstract:
A COLORED THERMOPLASTIC RESIN IS APPLIED IN FILM FORM OR AS POWDER ONTO THE SURFACE OF AN UNCURED FORMULATED LOW PROFILE POLYESTER SHEET AND IS THEN BONDED THERETO WITH HEAT, FORMING A LAMINATE OF THE CURED POLYESTER WITH CONTINUOUS, ADHERENT OVERLAYERS OF THE COLORED THERMOPLASTIC RESIN. A METHOD FOR COLORING POLYESTER SURFACES AFTER MOLDING WITH PIGMENTED THERMOPLASTIC RESIN POWDER IS ALSO DESCRIBED.
