Abstract: A method of making a sealed alkaline storage battery including a positive paste nickel electrode containing cobalt and/or cobalt oxide and a negative electrode stacked upon the positive electrode with a separator interposed therebetween in a battery container which is sealed within about one hour after pouring an alkaline electrolyte into the container. An initial charging of the sealed battery is provided within about 10 hours after the completion of the pouring of the electrolyte to provide an initial ampere-hour charge to the battery of about 5% or more of the battery's rated capacity. This method avoids formation of HCoO.sub.2.sup.- ions which cause short-circuiting of the battery.

Abstract: Organosilicone materials that are "density-matched" to the hydrocarbon medium also act as defoamers in hydrocarbon fuel, specifically as described herein for diesel fuel. Specifically these new defoamers can be described as alkylmethylsiloxanes. They have the characteristics of being slightly soluble or insoluble in water and hydrocarbon fuels. By changing the solvent and the method of dispersion, different particle size distributions are obtained.
