Abstract: Stable easily pourable aqueous fabric softening compositions based on water-dispersible lecithin are provided. The softening component comprises from about 1-20% by weight of the composition. Methods for making the composition are also described. Softening performance is comparable to that obtained by using quaternary ammonium compound softeners. The softener compositions are primarily intended for use in the rinse cycle of an automatic washing machine.

Abstract: Stable aqueous fabric softening compositions based on water-dispersible cationic fabric softeners such as the di-long chain, di-short chain quaternary ammonium salts are provided using synergistic proportions of fatty alcohols to enhance the softening performance. Both concentrated and ready-for-use formulations can be prepared. The active ingredients concentration in the concentrated formula is generally in the range of 11 to 20% by weight while for the ready-for-use formulations, concentration of the active ingredients may range from about 3 to about 8% by weight. In either case, the weight ratio of cationic softening agent to fatty alcohol being in the range of from about 4.5:1 to 3.5:1. These compositions have low viscosity and are easily dispersible in cold water and are storage stable. Water soluble electrolytes can further reduce viscosity and ethoxylated amines can further increase stability. Methods for making the compositions are also disclosed.

Abstract: Stable concentrated aqueous fabric softening compositions based on water-dispersible di-longchain, di-short chain quaternary ammonium salts are provided utilizing ethoxylated amine salts and water-soluble electrolyte. The softening quaternary component comprises from about 12-20% by weight of the composition; the amine salt from about 0.5 to about 10% preferably about 1 to 7% by weight and the electrolyte from about 0.1 to 1.5% by weight. Ratios of quaternary compound to amine salt may vary from about 40:1 to 2:1 and preferably from about 10:1 to 5:1. Methods for making the composition are also described.

Abstract: A synchronous electrical machine including a fixed superconducting field winding to provide D.C. magnetic field when a D.C. current circulates through the winding. A fixed normally conducting armature is provided with a plurality of spaced-apart disks. Each disk is made from insulating material and is provided with flat windings for circulation of A.C. currents. A plurality of rotor disks is axially interleaved with the disks of the armature. Each rotor disk produces A.C. electromagnetic forces in the flat windings upon rotation of the rotor.

Abstract: The improvement in a light duty detergent composition containing anionic sulfonated surfactants or mixtures of anionic sulfonate and nonionic surfactants is disclosed which comprises the inclusion therein of an effective amount of a low molecular weight organic diamine diacid salt selected from the range wherein the mole ratio of mono-anionic detergent to organic diamine diacid salt is from 0.8:1 to 9:1 and sufficient to improve soft water foaming and degreasing properties. These compositions are especially suitable for dishwashing.

Abstract: A clear, single phase, liquid cleaning composition particularly suitable for cleaning hard surfaces which leaves a low residue on unrinsed, cleaned surfaces consisting essentially of, by weight, 2-8% of an amine salt of an anionic sulfated or sulfonated detergent containing an alkyl radical of 8 to 22 carbon atoms in the molecule, 1-4% of water-soluble, ethyleneoxylated nonionic detergent, 2-15% of an amine salt of C.sub.1 -C.sub.3 monocarboxylic acid builder, 0.1%-4% of amine, 0-2% of an amine salt of a C.sub.8 -C.sub.18 carboxylic acid, 0-8% of urea and water, the weight ratio of builder to total detergent being in the range of 1:6 to 5:1 and said amine being selected from the group consisting of mono-, di- and tri-ethanol amine and etheylene diamine. Preferred compositions contain either the diethanolamine salts or the 2-aminoethylammonium salts.
