Abstract
Abstract A method for producing a fog to extract freezable moisture from plants and to increase the ambient humidity and temperature surrounding plants comprising the steps of providing a mixture of silicon tetrachloride and an emulsifier in the proportion of between about 20% to 90% of silicon tetrachloride and between about 80% and 10% of emulsifier, combining the silicon tetrachloride-emulsifier mixture with an aqueous ammonia solution containing between 28% and 33% of ammonia in an amount of between about 1 part of the silicon tetrachloride-emulsifier solution to between about 2.5 and 3 parts of the ammonia solution to produce a fog containing ammonium chloride which removes moisture from the plants and increases the ambient humidity surrounding the plants to thereby raise the ambient temperature.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
108 words
A method for producing a fog to absorb moisture from plants and increase the ambient humidity surrounding the plants to prevent frost damage comprising the steps of providing in relatively sufficient amounts, silicon tetrachloride, an emulsifier, and ammonia, and forcibly combining said silicon tetrachloride, emulsifier and ammonia, said silicon tetrachloride and said ammonia and said emulsifier combining to form an atmospheric fog containing ammonium chloride and silicone dioxide and emulsifier to absorb moisture from plants and raise the ambient humidity surrounding the plants, to thereby aid in avoiding the rupture of the cells of said plants as a result of the freezing of said moisture in said cells.
Claim 2
Independent Claim
108 words
A method for producing a fog to absorb moisture from plants and increase the ambient humidity surrounding the plants to prevent frost damage comprising the steps of providing in relatively sufficient amounts, silicon tetrachloride, an emulsifier, and ammonia, and forcibly combining said silicon tetrachloride, emulsifier and ammonia, said silicon tetrachloride and said ammonia and said emulsifier combining to form an atmospheric fog containing ammonium chloride and silicone dioxide and emulsifier to absorb moisture from plants and raise the ambient humidity surrounding the plants, to thereby aid in avoiding the rupture of the cells of said plants as a result of the freezing of said moisture in said cells.
Claim 3
Dependent Claim
