摘要: An article of manufacture and a method are disclosed herein for improving lubricity and wear resistance of a given substrate by applying thereto a solution consisting essentially of a dialkanolamine and a halogenated hydrocarbon carrier. The composition herein disclosed has been found to be most effective as preservatives for coating sundry substrates, especially gramophone or phonograph record surfaces whereby there is effected a marked reduction of record groove wear while substantially minimizing noise and harmonic distortion. The preferred composition herein contemplated and disclosed is one consisting essentially of a N-alkyl-substituted N,N-dialkanolamine and a halogenated hydrocarbon carrier, said dialkanolamine having the formula:(HOR.sub.1).sub.2 N--R.sub.2wherein R.sub.1 is alkylene selected from the group consisting of ethylene, isopropylene and propylene and R.sub.2 is alkyl having four to 20 carbon atoms.

摘要: A method of conditioning a phonograph record comprises applying a very thin film thereto of a quaternary ammonium salt having at least one long hydrocarbon chain. Preferred compositions have the formula ##STR1## wherein R.sub.1 is a hydrocarbon radical having from 8 to 22 carbon atoms, R.sub.2 is a hydrocarbon radical having 8 to 22 carbons, C.sub.1 -C.sub.4 alkyl, quaternary ammonium alkylene, or benzyl, and R.sub.3 and R.sub.4 are C.sub.1 -C.sub.4 alkyl or -(CH.sub.2 CH.sub.2 O).sub.n H, wherein n is an integer from 1 to 20, and X is a water-soluble salt-forming anion. Especially preferred compounds are quaternary ammonium compounds having at least one tallow radical. The compound is applied by spraying small quantities of a solution containing a minor amount of the salt dissolved in a solvent on a soft applicator, and pressing the applicator against the record while the surface is moving relative to the applicator.

摘要: A gramophone record includes a main body and a cladding layer. The main body is made of a polymeric material, and has a base surface and an extending surface which extends downward from the base surface. The extending surface defines a continuous spiral groove in the main body. The cladding layer is formed on the extending surface, and has a Hardness Rockwell C (HRC) of not less than 37.
