ABOUT ten years ago in the United States oils of the detergent type had come into rather general use for some diesel engine operation because they permitted longer periods of satisfactory operation than could be obtained with plain mineral oils. Since that time accumulated research and field service have shown that detergent type oils could be utilized to advantage and their field of use has broadened. How then can they be defined

WE are constantly emphasising, in our columns, of lubrication to industry. There is no industry which cannot obtain some benefits and some savings in lubrication and maintenance costs, by installing a system of mechanical and positive lubrication. It is doubtful, however, if any industry can gain as much from this type of lubrication system as the steel industry. The savings that can be effected in a steel mill can run into thousands of pounds per annum.

The automotive, aircraft and diesel engine fields have maintained one common trend toward increased power output, higher compression ratios, and resultant higher engine temperatures. As a result, the breakin and scuffing problems in engine design have become of prime importance wherever ferrous metals are used as bearing surfaces.

ON the basis of the kinetic theory, molecules in a liquid, at a given temperature, are at a certain energy level. Before the molecules can undergo a transition to a higher energy level they must acquire an activation energy designated by E. The Maxwell distribution law states that the number of molecules possessing sufficient energy for transition are in relation to the expression eERT where R is the gas particularly over extended temperature ranges, a study has been made of these deviations to ascertain whether they are anomalous or whether equation la fails to apply to such cases.

The current hypothesis on the mechanism of dry and boundary friction conceives solid surfaces in contact as forming very minute welds or adhesions on the isolated areas of true contact. When sliding occurs, these welds are broken and new ones are formed. Other phenomena may also take place during sliding, but the present paper deals only with observations of the adhesion factor.
