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 comprising a fluoroalkyl ester and an organic carrier. The compositions herein disclosed have been found to be most effective as preservatives for coating sundry substrates, especially gramophone or phonograph record surfaces whereby there is effected a reduction of record groove wear while substantially reducing the friction between the stylus and the record groove. A preferred composition herein contemplated and disclosed is one comprising a perfluoroalkyl ester of stearic acid and a halogenated hydrocarbon carrier.

The present invention relates to materials, methods and apparatuses for performing imprint lithography using amorphous metallic materials. The amorphous metallic materials can be employed as imprint media and thermoplastic forming processes are applied during the pattern transfer procedure to produce micron scale and nanoscale patterns in the amorphous metallic layer. The pattern transfer is in the form of direct mask embossing or through a serial nano-indentation process. A rewriting process is also disclosed, which involves an erasing mechanism that is accomplished by means of a second thermoplastic forming process. The amorphous metallic materials may also be used directly as an embossing mold in imprint lithography to allow high volume imprint nano-manufacturing. This invention also comprises of a method of smoothening surfaces under the action of the surface tension alone.
摘要:
A player for a multi-aroma cartridge constituted by a planar array of like frame assemblies held within a multi-section framework, each assembly being formed by a pad of absorbent material sandwiched between a pair of frames whose margins are joined together to define a central zone exposing the pad. The pad of each assembly is impregnated with a liquid fragrance that differs from those of the others. When the cartridge is inserted in a slot in the player case, it lies over a complementary honeycomb, each of whose cells is then in registration with a respective assembly. The cells are provided with individual electric heaters such that when a selected cell heater is energized, it heats the air in the cell to produce a positive pressure therein that acts to force the heated air through the zone to volatilize the liquid fragrance, the resultant aromatic vapor being discharged into the atmosphere through vents in the case. The selection of aromas to be played may be effected manually or it may be synchronized to follow the scenes of a video tape or movie film presentation.
摘要:
Phonograph record molding compositions having polystyrene as the major constituent are formulated to have wear resistance properties superior to other polystyrene injection molded compositions while generally retaining the transparency of unmodified polystryene. Ethylene-bis-stearamide or a homolog or analog thereof is dissolved within styrene monomer and then the monomer is polymerized to obtain a polystryene matrix having a molecular distribution of ethylene-bis-stearamide or the like within and throughout the matrix. Preferably, the ethylene-bis-stearamide or the like is combined with a wax such as an olefin-based wax or a microcrystalline wax.

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 twenty carbon atoms.
摘要:
A record disc containing grooves whose walls undulate to constitute a spatial representation of the time variation of a signal to be reproduced by means of a pressure responsive playback head carrying a stylus which engages in the groove and elastically deforms the groove walls to a substantial degree, the resulting elastic restoring force being sensed by the head, the disc having a modulus of elasticity of no more than 10,000 Kgf/cm2.
