Abstract:
The extreme pressure properties of ferrous metals can be increased by coating the metal with iron sulfide or chloride or mixtures thereof then heat treating the coated metal at a temperature in the range of 900*-2,000* F. for 1/2 to 24 hours. When metal Falex pins and jaws are treated in the above fashion they have longer running times, i.e., up to 11 times, than untreated pins and jaws under the same conditions in a standard Falex testing apparatus.
Abstract:
A PETROLEUM WAX COATING, WHICH COVERS THE ENTIRE AREA OF A VINYLIDENE RESIN COATED SUBSTRATUM AS AN OUTER LAYER OF UNIFORM THICKNESS, IS OBTAINED BY THE ADDITION OF A SMALL AMOUNT OF AN ESTER OR MIXTURE OF ESTERS OF A FATTY ACID AND A POLYHYDRIC ALCOHOL TO THE WAX BEFORE APPLICATION.
Abstract:
The rate at which a porous paper product absorbs paraffin waxes having a melting point of at least 136* F. (AMP) at an impregnation temperature less than 17* F. greater than the melting point of said wax is substantially increased by the addition of a small amount of an ester or mixture of esters of a fatty acid and a polyhydric alcohol to the wax before application.
