Abstract:
A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant is described. Oil filter is a chemical filter that includes filtration media (24) which includes particles(30) including an internal pores (32) formed within individual particles and interstitial pores (34) formed between adjacent particles (30) wherein the internal pores (32) and the interstitial pores (34) collectively define filtration media pores and a strong base material is associated with at least some of the internal pores (32). The filtration media (24) has a surface area greater than or equal to 25 square meters per gram that is derived from filtration media pores that are large enough to receive a combustion acid-weak base complex contained within oil flowing through the chemical filter.
Abstract:
The present invention provides a water based friction control composition comprising a binder a rheological control agent, and optionally a lubricant. The liquid friction control composition may also comprise other components such as a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing lateral force, reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the composition to metal surface, for example a top of rail or wheel, is also provided. The composition may be sprayed onto the rail surface.

Abstract:
A rolling bearing which has a satisfactory life at a low cost even under such service conditions that water is incorporated into a lubricant either externally or due to dew condensation, or that vibration has an influence, and is particularly suitable for electrical equipment and accessories of automobile engines, such as alternators. The hydrogen ion index pH of a grease sealed in the interior of the bearing is adjusted to 7 to 13. For attaining similar effects, the pH of the grease is adjusted to 5 to 13 when an organic metal salt or ADTC has been added in a predetermined amount to the grease, when an inorganic compound having an average particle diameter of not more than 2 mu m has been added in a predetermined amount to the grease, or when a diurea compound containing an aromatic amine or a mixture of diurea compounds has been added as a thickening agent to the grease.

The disclosure relates to temporary corrosion resistant coatings and films upon metal substrates, e.g., metal tools and dies. The temporary coatings and films will not adversely chemically alter the surface of the underlying substrate. The coatings/films comprise a mixture of at least one of an acrylic, water, an oil, silica, at least one silicate, surfactants and optionally one or more buffering materials and waxes.
Abstract:
The invention relates to a method for the production of a cooling lubricant emulsion mixed with water, used for metal cutting, whereby a) 2-15 parts by weight of a water-miscible concentrate of a coolling lubricant emulsion are mixed with 98-85 parts by weight of water, so as to obtain a mixture comprising 100 parts by weight, and then b) one disperses 1-14 parts by weight of a non water-miscible native-based cutting oil are dispersed, with strong shearing action into mixture a). The cutting oil is preferably chosen from oxidation-stabilized fatty acid glycerides in the form of triesters with three fatty acids with 14-22 C-atoms per fatty acid, and oxidation-stabilized diesters with two fatty acids with 12-22 C-atoms per fatty acid. The invention further concerns a cooling lubricant emulsion that can be produced by this method, and its use for metal cutting.
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:
The invention concerns a friction-reducing additive for water-miscible or non-water-miscible cooling lubricants which contains: a) bismuth compounds of organic acids; and b) sulphurous organic compounds, in a mixture ratio such that the sulphur content of the additive ranges from 2 to 30 wt % and the bismuth content ranges from 1 to 25 wt %. The invention further concerns the use of this additive in the minimal lubricating technique and as a friction-reducing additive for non-water-miscible cooling lubricants and water-mixed cooling lubricants and their concentrates.
Abstract:
This invention relates to novel water soluble metal working fluid compositions, their use to work metal, a process for working metal using such compositions and the metal worked article of manufacture. More particularly, this invention relates to fluid compositions useful in cutting, grinding, shaping and other metal working operations which require a lubricant. The terms "first Group A" and "second Group B" are used herein to denote different groups and not to indicate any sequence of use or selection as any possible combination or sequence of use of a component(s) is envisioned without limit of any kind. The disclosed fluid compositions are also anticorrosive and environmentally more acceptable than current oil based fluids. There has now been discovered an essentially odorless, substantially non-oil misting, water-soluble metal working fluid comprising at least one component selected from a first Group A herein and optionally one or more components selected from a second Group B herein preferably with the balance of the composition being water and other (optional) minor ingredients. When a component is employed from Group A and a component is employed from Group B the action of the combination generally enhances performance of the resulting combination with contain moieties from both Group A and Group B.
