Abstract: A method for constructing and breaking in piston engines includes applying an integral phosphate layer to the interior cylinder wall prior to the insertion of the piston into a cylinder. The invention includes the improved engine so constructed. The phosphate layer decreases oil consumption and improves piston ring seating in such an engine. The phosphatizing solution includes a zinc or manganese salt in phosphoric acid at a pH between about 2.5 and 4.

Abstract: The invention encompasses a petrolatum wax-biocidal composition and a method of preserving wood with the composition.

Abstract: Plastic polyolefins which are resistant to photodegradation are combined with polyisobutylene to improve photodegradability.

Abstract: Disclosed is a process for joining two metal surfaces together with solder in which the surfaces to be soldered are first treated with an organic phosphorus-containing liquid flux which is relatively non-corrosive and which has a high degree of lubricity.

Abstract: Wax-flux compositions for use in soldering processes comprising: (a) a major amount of a wax; and (b) an effective amount to cause fluxing, at or below the temperature of the piece to be soldered, of a wax-dispersible C.sub.12 to C.sub.28 aliphatic carboxylic acid.

Abstract: Wax-flux compositions for use in soldering processes comprising: (a) a major amount of a wax; and (b) an effective amount to cause fluxing, at or below the temperature of the piece to be soldered, of a wax-soluble, phosphorus-containing acid.

Abstract: Disclosed is a wax-flux composition and a process for making a wax-flux composition comprising a normally solid chlorinated wax having a chlorine content below about 60 weight percent.

Abstract: Wax-flux compositions for use in low-temperature soldering processes comprise (A) a major amount of a wax and (B) an effective amount to cause fluxing, at or below the soldering temperature of the piece to be soldered, of a wax-soluble alkylaryl sulfonic acid. A process for soldering electrical components to a printed circuit board comprises (A) applying a molten wax-flux composition as described above to the metal pattern side of the board, (B) allowing the wax-flux composition to solidify, (C) trimming the component leads, and (D) soldering the components to the printed circuit board.

Abstract: A lead-free candle wick composition comprising a combustible wick and a stiffening agent is disclosed. The stiffening agent comprises a substantially wax-insoluble polymer or copolymer which has a Vicat softening point at least 2.5.degree.C. higher than the melting point of the candle wax and which depolymerizes or pyrolyzes to substantially completely combustible products at a temperature above said melting point and at or below the temperature of the candle flame.
