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
29 words
A method as set forth in claim 1 wherein said silicon tetrachloride, emulsifier, and ammonia are combined by forcibly mixing them after expelling them from nozzles into the atmosphere.
Claim 4
Dependent Claim
20 words
A method as set forth in claim 2 wherein said ammonia is in the form of an aqueous ammonia solution.
Claim 5
Dependent Claim
33 words
A method as set forth in claim 1 wherein said silicon tetrachloride and said emulsifier are premixed for ejection from a first nozzle and wherein said ammonia is ejected from a second nozzle.
Claim 6
Dependent Claim
17 words
A method as set forth in claim 4 wherein said forcible combining is effected by a turbofan.
Claim 7
Dependent Claim
20 words
A method as set forth in claim 4 wherein said ammonia is in the form of an aqueous ammonia solution.
Claim 8
Dependent Claim
51 words

Dependent Claim
51 words
A method as set forth in claim 10 wherein said ammonia is in the form of an aqueous solution and is combined with said silicon tetrachloride-emulsion in an amount of between about one part silicon tetrachloride-emulsion by volume to 2-3 parts of aqueous ammonia of a concentration of 28% by weight.
Claim 13
Dependent Claim
20 words
A method as set forth in claim 10 wherein said ammonia is in the form of an aqueous ammonia solution.
Claim 14
Dependent Claim
20 words
A method as set forth in claim 1 wherein said ammonia is in the form of an aqueous ammonia solution.
Claim 15
Dependent Claim
23 words

Claim 17
Dependent Claim
17 words
A method as set forth in claim 1 wherein said forcible combining is effected by a turbofan.
Claim 18
Dependent Claim
50 words
A method as set forth in claim 1 wherein said silicon tetrachloride is present relative to said emulsion in an amount of between about 20% and 45% by weight and wherein said emulsifier relative to said silicon tetrachloride is present in an amount of between 80% and 55% by weight.
