Abstract: An Otto-cycle engine fuel containing a small amount of an amide, amide/ammonium salt and/or ammonium salt of an aminoalkylene polycarboxylic acid and a long-chain secondary amine as additive for cleaning the carburetor and valves.

Abstract: Novel alkoxylated polyetherdiamines are useful as gasoline additives, for keeping carburetors and valves clean, and as lubricant additives.

Abstract: The invention relates to a fuel for gasoline engines and diesel engines, containing small amounts of an ester of a mono- and/or poly-carboxylic acid with an alkyl alkanolamine or alkyl aminopolyalkylene glycol of the general formula I ##STR1## in which R.sub.1 is a C.sub.6 -C.sub.30 -alkyl radical,R.sub.2 is a C.sub.6 -C.sub.30 -alkyl radical or a hydroxyalkyl radical of the general formula II ##STR2## and R.sub.3 is a hydroxylalkyl radical of formula II, in which R.sub.4 is hydrogen or a C.sub.1 -C.sub.6 -alkyl radical and m is an integer from 0 to 100.

Abstract: Highly viscous adducts of 1,2-butylene oxide with secondary or primary alcohols are prepared in the presence of an alkali as a catalyst.

Abstract: Adducts of 1,2-butylene oxide with H-azidic organic compounds are used as lubricants, and lubricants contain these adducts.

Abstract: A sample of a fuel/oil/additive mixture is metered continuously to a channel-like, inclined test element along which there is an increasing temperature profile. Under the increasing action of heat on the flowing mixture, solid residual products form on the test element after a certain flow distance. Their weight and the flow distance are evaluated in order to evaluate the additive.

Abstract: An amino group containing graft polymer comprising a main chain polymer having allyl amine grafted onto it whereby the main chain polymer is a hydrogenated olefin/diene copolymer and the total nitrogen content of the graft copolymer is from 0.001 to 0.05 weight percent.

Abstract: Grinding, lapping, and polishing compounds containing an abrasive material, a thickener, and a water-soluble alkylene oxide polymer. In addition to good applications-related characteristics, said compounds have the advantage of permitting the workpieces to be cleaned with water.

Abstract: This invention concerns a new carrier catalyst, the active mass of which contains silver, a process for its manufacture and a process for the manufacture of ethylene oxide by reacting oxygen-containing gases with ethylene by using this catalyst. This carrier catalyst comprising a carrier material and a catalyst, the active mass of which is 20 to 90 percent by weight of silver, 0.005 to 5 percent by weight of lithium, and 3 to 70 percent by weight of SiO.sub.2 in free form or in the form of silicates, is extremely well suited for the manufacture of ethylene oxide by adding oxygen to ethylene.
