US Patent:

55115900, Apr 30, 1996
Filed:

Jul 27, 1993
Appl. No.:

8/097479
Inventors:

David E. Turcotte - Woodhaven MI
John J. Conville - Canton MI
Stephen M. Zeld - Wyandotte MI
Daniel E. Coker - Grosseville MI
James T. Lyon - Novi MI
Assignee:

BASF Corporation - Parsippany NJ
International Classification:

B65B 1300
US Classification:

141 7
Abstract:

In an automotive cooling system made up of a radiator, overflow bottle, engine and heater core members, a method of removing spent antifreeze therefrom involves applying air pressure at the highest vertical point of the cooling system members, and draining the antifreeze via the lowest vertical point thereof. A method of refill via the radiator or pressurized overflow bottle involves utilization of a refill element with vacuum and coolant prongs. Simultaneous vacuum and refill of coolant is achieved with the refill element.

International Classification:

C10L 1/232
US Classification:

44347
Abstract:

A fuel additive composition includes a polyalkenylsuccinimide, a mono or polyfunctional polyisobutene amine, and a carrier oil selected from the group of mineral oils, polyethers, polyetheramines, esters, and combinations thereof. The polyalkenylsuccinimide includes the reaction product of a hydrocarbyl dicarboxylic acid producing reaction intermediate and a nucleophilic reactant. The hydrocarbyl dicarboxylic acid producing reaction intermediate includes the reaction product of a polyolefin comprising Cto Colefin units and having a number average molecular weight (M) of about 500 to 5,000 g/mol and a Cto Cmonounsaturated acid reactant. The hydrocarbyl dicarboxylic acid producing reaction intermediate includes from 0.5 to 10 dicarboxylic acid producing moieties per molecule of the polyolefin. The nucleophilic reactant is selected from the group of amines, alcohols, amino alcohols, and combinations thereof.
