This invention relates to the composition of an emulsion and a method of producing a stable, wax semi-solid by aeration of the emulsion. The emulsion contains wax, water, a primary mono or secondary dialkanolamine, and an aliphatic monocarboxylic acid in the proportions of about 25 to 75 weight percent water, about 20 to 65 weight percent of a normally solid hydrocarbon wax, about 1 to 15 weight percent of the alkanolamine, and about 3.5 to 15 weight percent of the acid. The aeration can be acco...

The subject invention pertains to a continuous process for the production of aqueous paraffin emulsions. A primary emulsion is first formed by subjecting water and paraffin in admixture with an emulsifier and a portion of recycled primary emulsion to heat and turbulent flow. The stability of the primary emulsion is then improved by mixing said primary emulsion with another emulsifier and a portion of a recycled secondary emulsion and subjecting the mixture to heat and turbulent flow to produce s...

A method for making hydrophobic sand including coating sand with a wax blend so as to form a coated sand with advanced hydrophobic properties, wherein a weight ratio of the wax blend to total coated sand weight is about 0.05% 10%, and the wax blend includes a weight ratio of about 50.01% to 99.99% of a main wax, and about 49.99% to 0.01% of a secondary wax.

Herbicide safener combiantions consisting of A) an effective amount of a compound of the formula (1) or a salt thereof, in which R.sup.1 is phenyl which is unsubstituted or substituted, R.sup.2 is (C.sub.1 C.sub.6)alkyl, (C.sub.3 C.sub.6)cycloalkyl or phenyl, each of the 3 last-mentioned radicals is unsubstituted or substituted, R.sup.3 is hydrogen or a hydrocarbon radical having 1 to 18 C-atoms which is unsubstituted or substituted, and B) a herbicide selected form the group consisting of and f...

Water based waxing mixtures for protecting surfaces providing ionically neutral ingredients adhering to the surface while repelling environmental impurities, such as dirt. Surface precleaning need not precede the wax application because of an exchange, which takes place between the mixture and surface dirt. The mixture constitutes an emulsion of an organic phase in an aqueous phase. The aqueous phase amounts to 70 percent to 92 percent by weight, while the organic phase provides the remainder of...

In a device for handling sheets of media in a stack, a picker bar for engaging the edge of a media sheet covers only a portion of the width of the sheet. The picker bar is rotated to shape the edge into a curve thus stiffening the edge so that it may be removed from the stack. The sheet, so engaged, may be conveyed or disposed of as required.
