Lubricating compositions, particularly useful for manufacturing multigrade oils, hydraulic fluids, oils for industrial gears and cutting oils, comprising 5 - 95 percent by weight of a hydrocarbon oil produced according to a conventional process and 5-95 percent by weight of a compound selected from the group consisting of the esters of polyalkyleneglycol ethers complying with the general formula: ##SPC1## Wherein R.sub.1 is a divalent hydrocarbon radical having from one to 34 carbon atoms, R.sub...

Lubricating oil compositions for internal combustion engines having unexpectedly wide temperature operating characteristics, contain a combination of 2-block copolymer comprising a first polymer block of an alkenyl arene, e.g., styrene and a second essentially completely hydrogenated polymer block of isoprene and certain pour point depressants in a lubricant base stock having a viscosity index of at least 85. The compositions have excellent shear stability and can be formulated to pass a number ...

In a process of the preparation of a diarylide pigment composition by coupling a tetrazotized pigment benzidine with a pigment coupling agent and incorporating in the pigment a watersoluble dyestuff, preferably diarylide dyestuff, the step of subjecting the obtained pigment composition to a conventional solvent treatment, of additionally incorporating in the pigment composition a fatty alcohol, diol or polyol containing from eight to 22 carbon atoms or an aliphatic amine, amine salt or amine oxi...

A method of reducing intake valve deposits formed in a spark ignition gasoline-fueled internal combustion engine is disclosed. The method features the use of gasoline containing a deposit reducing amount of a high molecular weight alkyl aromatic hydrocarbon or mixture of alkyl aromatic hydrocarbons. The gasoline compositions and gasoline additive concentrates are also disclosed.

In concrete compositions based on hydraulic cement, improved properties in respect of workability, especially mouldability, capacity for being impelled along a pipe as by pumping, and frost resistance in the concrete, are obtained by incorporating in the composition a minor proportion of dispersed cellulose fibres such as paper making fibres.

The gelling tendency of lubricating oil solutions containing selectively hydrogenated random styrene/butadiene copolymers is minimized by the presence of a polyester of an olefinically unsaturated acid.

Stable dispersions or suspensions of solid metal or metal hydride particles or powders in liquid hydrocarbons in mobile thixotropic suspensions are prepared by mixing metals and their hydrides into hydrocarbon slurries with a gellant of a monoester of a C4-18 hydrocarbyl mercapto methyl phosphonic acid.

Adhesion of thermoplastic elastomers, such as unvulcanized styrene-butadiene rubber, to a solid substrate is obtained by using a primer containing a tackifier component, such as hydrogenated rosin or a coumarone-indene resin, and an amino-functional trihydrolyzable silane, partial condensates and hydrochloride salts thereof in which the amino-functionality is in the form of a primary or secondary amine.

Compounds having the formula: ##SPC1## Wherein X is halogen and the non-toxic, pharmaceutically-acceptable inorganic and organic salts thereof. Antiinflammatory compositions consisting essentially of at least one of said compounds in admixture with a non-toxic, pharmaceutically-acceptable carrier. A method for reducing inflammation of the tissues in mammals comprising administering a therapeutically effective concentration of at least one of said compounds, preferably in admixture with a non-tox...
