Abstract:
Agent for the pickling of and as an antioxidant for workpieces made of iron and steel in the case of when they are subjected to non-cutting, hot transformation. The agent is used in dry form. The agent contains: (a) 20 to 80 percent by weight of a pickling-effective compound, such as, sodium metaborate; (b) 1 to 80 percent by weight of a component, such as, graphite; and (c) zero to 79 percent by weight of at least one substance selected from group (d), (e) and/or (f). Zero to 35 percent by weight of group (d), such as, coke, can be used as substance (c) and, for example, act as antioxidants. Zero to 50 percent by weight of group (e), such as, sodium chloride, can be used as substance (c), and control the physical characteristics. Zero to 5 percent by weight of group (f), such as, ammonium chloride, can be used as substance (c) and, for example, act on the reduction of the oxides of group (a).
Abstract:

Abstract:
A method of extending the lubricant life in an internal combustion engine which has a crankcase connected to a source of gaseous ammonia, comprises feeding ammonia gas to the crankcase at a rate proportional to the level of acidic species in the compressed working fluid prior to combustion.
Abstract:
The present invention relates to a method of lubricating a conveyor belt wherein a lubricant concentrate containing at least one fatty acid is employed in a dry lubrication process at a pH- value of 5 is applied to the surface of the conveyor belt on which the lubricant concentrate has been applied earlier.
Abstract:
A composition comprises a sulphur free reaction product of: (a)(i) a hydrocarbyl substituted aromatic compound containing an acidic group selected from the group consisting of a carboxylic group, a hydroxyl group and mixtures thereof; and (a)(ii) an organic nitrogen-containing base reacted with the acidic group. The composition is obtained by a preparatory process and is useful in a method for lubricating an internal combustion engine to include where the lubricant has reduced levels of sulphur, phosphorus and sulphated ash.
Abstract:
According to the invention there is provided a method of reducing wear of one or both of two steel elements having surfaces in sliding or sliding-rolling contact. The method involves applying an HPF friction control composition to one, or more than one contacting surface of one or both of the two steel elements. In a particular example, the HPF friction control composition comprises a rheological control agent, a lubricant, a friction modifier, and one, or more than one of a retentivity agent, an antioxidant, a consistency modifier, and a freezing point depressant.
