Abstract: A vitreous bonded abrasive article, more particularly a grinding wheel, having improved grinding performance is provided wherein the open pores of the abrasive article contain an impregnant which comprises at least one water insoluble, sulfur bearing organic substance having at least one carbon to sulfur bond, at least about 5% by weight sulfur and a melting point of at least about 30° C. said melting point being at least 10° C. below the decomposition temperature of the substance and selected from the group consisting of substituted and unsubstituted aliphatic, aromatic, cycloaliphatic, alkenyl, alkynyl, alkylaryl, arylalkyl and substituted heterocyclic sulfur bearing organic substances or a mixture of said substances grinding aid. The impregnant is free of a medium, other than the water insoluble, sulfur bearing substance, in which the substance or a mixture of such substances is dissolved or dispersed.

Abstract: An aqueous machining fluid composition having improved resistance to microorganisms is provided. The fluid composition comprises in admixture: a) water, b) a water insoluble organic lubricant, c) a surface active agent selected from the group consisting of nonionic, anionic having up to and including 12 carbon atoms, and cationic surfactants and mixtures thereof and d) a water soluble polyquaternary cationic biocide. Machining processes comprising the step of supplying said aqueous machining fluid to the interface between the tool and the workpiece are also provided.

Abstract: An aqueous functional fluid composition free of formaldehyde and formaldehyde producing agents, more especially an aqueous metalworking fluid composition, having improved resistance to attack by microorganisms is provided. This fluid comprises a) water, b) a water soluble or dispersible functioning agent (e.g. water soluble or dispersible organic lubricant) and c) an antimicrobial effective amount of the combination of d) a water soluble or dispersible nitrogen bearing organic compound (e.g. monoethanolamine) and e) a water soluble or dispersible haloalkynylalkyl carbamate (e.g. 1-iodo-3-propynylbutyl carbamate).

Abstract: Aqueous machining fluid compositions, especially aqueous metalworking fluid compositions, are provided that exhibit improved reduction of friction and forces in the mechanical shaping and working of metallic and solid non-metallic workpieces. These compositions comprise a) water, b) a sulfurized organic material selected from the group consisting of sulfurized unsaturated aliphatic carboxylic acids having from 6 to 22 carbon atoms and salts thereof, sulfurized unsaturated esters of aliphatic carboxylic acids having 1 to 22 carbon atoms, sulfurized polymerized unsaturated fatty acids and salts and esters thereof, and mixtures thereof, c) a sulfurized hydrocarbon and d) an aliphatic ester of a dialkyldithiocarbamic acid.
