Abstract: The Diels-Alder adduct of 2,3 and 6,7 poly(alloocimene) and an activated olefin such as maleic anhydride serves to inhibit the corrosion of metals. The adduct or a derived polyamine reaction product in admixture with an oil such as a petroleum oil or grease is effective to inhibit rusting of ferrous metals.

Abstract: Novel apparatus for assembling box blanks and liners are provided. The apparatus includes supports for stacks of box blanks and liners and a laminating table disposed to receive blanks and liners from the supports. Also included is shuttle apparatus disposed between the supports and the laminating table for gripping and lifting the blanks and liners and taking blanks and liners from the supports to the laminating table and placing them in proper registration. The shuttle apparatus can further include means for dropping the liner onto the blank prior to final registration. The invention is highlighted by a single pushing mechanism for aligning both the blank and liner in a single direction. The invention further includes adhesive applying apparatus which minimizes maintenance due to adhesive overspray and indexing carriers which minimize registration errors.

Abstract: A process of producing high quality extrusion coated paper for high quality printing by extruding polyethylene on a highly smoothed base sheet of paper and passing the coated base sheet through the nip of two cooperating rollers, at least one of which rollers is a low-friction gloss chill roller having a surface finish with a degree of roughness between that of a high gloss roller and a matte finished roller.

Abstract: The disclosure is of the use of chrome humate derivatives to reduce the viscosity of and/or to prevent fluid loss in water-based drilling fluids. The composition is much more effective as a drilling mud thinner, and as a fluid loss control agent than the commercially available ferrochrome lignosulfonate, chrome lignite or humate compositions.

Abstract: A device for dispensing volatile fragrances comprises a hollow body, and a liquid volatile fragrance contained within the hollow. The liquid volatile fragrance diffuses through a closure member made of a silicone rubber body, to the outer surface where it is volatilized to disperse in the surrounding atmosphere.

Abstract: Tricarboxylic acids are prepared by reacting unsaturated mono- and dicarboxylic acids of specific carbon atom content in the presence of a catalytic proportion of an unactivated clay and water. The product acids of 34, 35, 36, 38, or 40 carbon atoms are useful as corrosion inhibitors, epoxy resins curing agents, lubricants, polymeric resin plasticizers and intermediates for synthetic polymeric resins.

Abstract: The present invention comprises a water dispersible polyamide diethanolamine ester, having the following general structure: ##STR1## wherein x is an integer of 0-5; R.sup.1 is independently at each occurrence an aliphatic group of up to 40 carbon atoms or polyamide segment; R.sup.2 is independently at each occurrence ##STR2## (where B is an aliphatic group of up to 10 carbon atom) or ##STR3## where E is an aliphatic group of up to 10 carbon atoms or the residue of a cyclic carboxylic anhydride bearing at least one free carboxyl group; ##STR4## The product polyamide resin of the present invention comprises a mixture of monobasic and polybasic carboxylic acids, polyamines, DEA and cyclic carboxylic anhydrides. These resins may be used in various compositions including inks and laminates.

Abstract: The disclosure is of particular substituted ammonium humates useful as fluid loss control agents in oil-based drilling fluids. The humate bears a unique compositional make-up.

Abstract: A method is provided for the preparation of stable aqueous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamide resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquified by heating the polyamide resin to a temperature where it is at or above its melting point. The liquified polymerized fatty acid polyamide resin is then blended with a predetermined amount of water which is heated to a temperature such that the resulting blend will have a temperature above the melting point of the polyamide resin. A cationic surfactant which is the salt of the amine of the formula:R--NH--CH.sub.2).sub.n.sbsb.1 (NH--CH.sub.2).sub.n.sbsb.2).sub.n.sbsb.3 NH.sub.2wherein R represents an alkyl having 16-20 carbon atoms and n.sub.1 and n.sub.2 are the same or different and each represents a whole number from 1-3 and n.sub.3 is 0 or 1, is included in the mixture.

Abstract: Polyamide hot-melt adhesives are prepared from condensation of a mixture of polymeric fatty acids and 1,18-octadecane-dicarboxylic acid or 1,16-hexadecanedicarboxylic acid and a substantially equivalent proportion of a polyamine.

Abstract: A process is disclosed for the production of polyalkyl tetrahydronaphthalenes is disclosed wherein a cyclialkylation reaction between an olefinic compound of the general Formula ##STR1## wherein R.sup.4, R.sup.5, and R.sup.6 are independently defined and each represents a substituent which does not substantially interfere with a Friedel-Crafts type reaction and where R.sup.5 and R.sup.6 are other than H, and a substituted benzene compound is carried out in the presence of a hydride abstracting reagent, an alkyl halide or hydrogen halide, a Lewis acid, and, optionally, a phase transfer agent.
