Abstract: The entire right, title and interest in and to this application and all subject matter disclosed and/or claimed therein, including any and all divisions, continuations, reissues, etc., thereof are, effective as of the date of execution of this application, assigned, transferred, sold and set over by the applicant(s) named herein to Deere & Company, a Delaware corporation having offices at Moline, Ill. 61265, U.S.A., together with all rights to file, and to claim priorities in connection with, corresponding patent applications in any and all foreign countries in/the name of Deere & Company or otherwise.

Abstract: An aerosol propellant for sealing punctures in tires comprises a methylene chloride-in-water emulsion comprising water, methylene chloride, a curable acrylonitrile-butadiene-styrene (ABS) polymer latex and a surfactant, the emulsion having been blended with a fibrous plugging/matting agent, a carbon dioxide containing propellant or propellant blend in an amount sufficient to at least partially inflate a tire, and a corrosion inhibitor. The tire inflator/sealer provides an ozone friendly product.

Abstract: An engine cleaner composition and method for removing carbonaceous deposits from engine fuel-system components such as mechanical and electronic fuel injectors, intake valve seats, valves, combustion cylinders, spark plugs, and oxygen sensors may be used on both gasoline and diesel engines. Preferred compositions comprise a synergistic solution of a heterocyclic ring compound in an azeotrope of acetonitrile and water, together with selected surfactants and aromatics. Preferred compositions of the invention may be placed in an aerosol pressurized unit utilizing a compressed gas, such as nitrogen or nitrous oxide, or compressed liquid gas, such as a hydrocarbon or fluorohydrocarbon. Preferred engine cleaning compositions of the invention are substantially non-ozone depleting, are low in global warming, and have a low order of human toxicity. Preferred compositions have a moderate pH and are essentially compatible with metals and elastomers conventionally used in engine fuel-system components.

Abstract: An aerosol propellant comprises a methylene-chloride-in-water water/out emulsion comprising water, methylene chloride and a surfactant and a propellant gas soluble in methylene chloride. A puncture sealing and inflating composition for pneumatic tires includes a methylene-chloride-in-water water/out emulsion comprising water, methylene chloride, and a surfactant; a nonflammable propellant gas soluble in methylene chloride; a curable latex emulsion; and a fibrous plugging/matting agent.

Abstract: A composition is disclosed which cleans baked-on, carbonized sludges and varnish deposits from the internal surfaces of automobile, motorcycle and truck engines. The product comprises a mutually synergistic solution of selected cyclic compounds, aliphatic amines and water, preferably dissolved in a hydrocarbon or hydrocarbon and aliphatic lower alcohol fuel base. The solution or base product may be placed in a pressure resistant (aerosol) dispenser, and pressurized. When injected into an engine over a period of time, significant removal of deposited contaminants occurs, resulting in smooth and efficient engine operation and lower levels of unburned hydrocarbon fuel, carbon monoxide, and other air pollutants.

Abstract: A trash handling apparatus for a self-cleaning rotary screen comprising two cutterbars that extend across the diameter of a circular screen and a comb having a castellated edge is secured to the leading edge of a vacuum chamber. The two cutterbars are provided with outwardly extending ribs that act in concert with notches formed in castellated edge of the comb to scissor large crop material trapped on the rotary screen as it passes the stationary vacuum chamber.

Abstract: A formulated composition is disclosed which is designed to clean baked-on, carbonized sludges and varnish deposits from the upper cylinder surfaces of automobile, motorcycle and truck engines. The product is comprised of a mutually synergistic solution of selected cyclic compounds, aliphatic amines and water, preferably dissolved in a hydrocarbon or hydrocarbon and aliphatic lower alcohol fuel base, to which minor materials may optionally be added. The solution or base product may be placed in a pressure resistant (aerosol) container pressurized with a compressed gas, such as nitrogen gas. A preferred embodiment of the invention utilizes a synergistic solution of N-methyl-2-pyrrolidone, n.butylamine and de-ionized water, with these ingredients present at certain ratios. This solution is dissolved in either mixed iso-(C.sub.7, C.sub.8)-hydrocarbons or a combination of such hydrocarbons with a minor amount of isopropanol, to which up to about 10% by weight of other optional ingredients may be added.

Abstract: An apparatus for cleaning the fuel injectors and combustion chambers of an internal combustion engine. The apparatus can safely be used "under the hood" of the engine and features a safety fitting which is designed to mate only with a compatible container of cleaning mixture.
