Abstract:
Tropospheric volume elements enriched with vital elements and/or protective substances as well as procedures for their production and application. The term “vital elements” applies to all matter supporting the development of life within the earth's biosphere and the term “protective substances” means all those substances which contribute directly or indirectly to the prevention of harmful effects on the earth's biosphere and in particular on man. Tropospheric volume elements in the form of clouds which contain contaminants and which can escape from industrial facilities due to damage or malfunction are enriched with protective substances which prevent the organism from taking in radioactive elements and minimize the extent of the area affected by the clouds and possess additional warning and identification properties.

Abstract:
Diesel fuels, particularly low sulfur diesel fuels, contain additives which increase the lubricity in the fuel and reduce the amount of smoke in the exhaust. These additives are esters having a viscosity of 3.0 cSt to 20.0 cSt at 100.degree. C. and a smoke index of at least 75.
Abstract:
Hydrocarbonaceous fuels and additive compositions therefor which comprise: a) one or more fuel-soluble manganese carbonyl compounds; and b) one or more fuel-soluble alkali or alkaline earth metal-containing neutral or basic detergent salts. These compositions preferably contain, in addition to components a) and b) above, one or more of the following: c) one or more fuel-soluble ashless dispersants; d) at least one fuel-soluble demulsifying agent; e) at least one aliphatic or cycloaliphatic amine; and f) at least one metal deactivator. The compositions possess improved combustion characteristics (e.g., formation of less soot, smoke, carbonaceous products and/or noxious emissions), and form on combustion carbonaceous products of reduced acidity. The deposition of sludge on critical engine or burner parts or surfaces is reduced and the fuels have improved stability and demulsibility characteristics. And the fuel compositions can result in decreased fuel consumption in diesel engines.
