Abstract:
A laundry oil containing 0.02 to 2.0 weight percent 8hydroxyquinoline as an antibacterial agent and the process of laundering mops and other fabrics used to wipe dust with such oil. In a preferred aspect of the invention the mops, etc. are laundered directly with the oil. When copper is present in the laundering apparatus the laundry oil preferably contains 0.0001 to 0.5 weight percent benzotriazole.
Abstract:
AN IMPROVED INVESTMENT CASTING WAX COMPOSITION CONSISTING ESSENTIALLY OF ABOUT 35-65 WEIGHT PERCENT REFINED PETROLEUM WAX, SOLID CHLORINATED POLYPHENYL, CERTAIN ESTER TYPE MONTAN WAXES, FISCHER-TROPSCH WAX, AND A METAL SOAP. SAID COMPOSITION HAS THE ADVANTAGE OF LOW SHRINKAGE, LOW PENETRATION AND RAPID SETUP.

AN IMPROVED INVESTMENT CASTING WAX COMPOSITION CONSISTING ESSENTIALLY OF ABOUT 35-65 WEIGHT PERCENT REFINED PETROLEUM WAX, SOLID CHLORONATED POLYPHENYL, ACID TYPE MONTAN WAX AND STEARIC ACID. SAID COMPOSITION HAS THE ADVANTAGE OF LOW SHRINKAGE, LOW PENETRATION AND RAPID SET UP.
Abstract:
A process for forming a golden-colored aluminum-surfaced article in which an aluminum-surfaced article is contacted with gaseous hydrogen sulfide and thereby creating said golden-colored surface.
Abstract:
Hot melt adhesives comprise a major proportion by weight of atactic polypropylene having a Brookfield viscosity of 4200 to 5800 cp at 300 DEG F. and a ring and ball melting point of 115 DEG to 121 DEG C., and a minor proportion by weight of at least one material selected from tall oil, terpene resins, polyethylene, isotactic polypropylene and hydrocarbon/aldehyde resins. Specified terpene resins are polymers of a - and b -pinene. The hydrocarbon/aldehyde resins may be derived from refinery feedstocks containing 15 to 15% aromatic hydrocarbons and formaldehyde, formalin, paraldehyde, trioxane, acetaldehyde, propionaldehyde or butyraldehyde, in the presence of catalysts such as sulphuric, hydrofluoric, formic and phosphoric acids, boron trifluorides and metal chlorides, particularly sulphuric acid or boron trifluoride in the presence of acetic acid. The adhesives may be used for laminating paper, aluminium foils and polypropylene and regenerated cellulose films. Examples describe the preparation of aldehyde resins by heating catalytic gas oil with paraformaldehyde in the presence of (III) boron trifluoride/acetic acid and (IV) sulphuric acid/acetic acid catalysts, and hot melt adhesive compositions comprising atactic polypropylene, phenolic antioxidant and (I) tall oil, (III-V) hydrocarbon/aldehyde resin and/or isotactic polypropylene, (VI and VII) a -pinene polymers and/or isotactic polypropylene, (VIII) isotactic polypropylene and (IX) polyethylene.
