Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
36 words
A coated legume seed in which the coating comprises an adhesive and viable rhizobia bacteria, wherein the adhesive contains a man-made caseinate salt formed by reaction of casein with a salt forming alkaline agent in solution.
Claim 2
Dependent Claim
36 words
A coated legume seed in which the coating comprises an adhesive and viable rhizobia bacteria, wherein the adhesive contains a man-made caseinate salt formed by reaction of casein with a salt forming alkaline agent in solution.
Claim 3
Dependent Claim
30 words
A coated legume seed as claimed in claim 1 in which the caseinate salt is a salt with an alkali metal, an alkaline earth metal, ammonia or an organic amine.
Claim 4
Dependent Claim
19 words
A coated legume seed as claimed in claim 1 wherein the salt is a salt with an alkali metal.
Claim 5
Dependent Claim
15 words
A coated legume seed as claimed in claim 3 wherein the alkali metal is potassium.
Claim 6
Dependent Claim
38 words
A coated legume seed as claimed in claim 1 wherein the caseinate salt is formed by reaction of casein with a salt forming alkaline agent in solution, and this solution is employed in the coating on the seed.
Claim 7
Dependent Claim
36 words
A coated legume seed in which the coating contains viable rhizobia bacteria and, as an adhesive, a material containing a man-made caseinate salt formed by reaction of casein with a salt forming alkaline agent in solution.
Claim 8
Dependent Claim
36 words
A coated legume seed in which the coating contains viable rhizobia bacteria and, as an adhesive, a material containing a man-made caseinate salt formed by reaction of casein with a salt forming alkaline agent in solution.
Claim 9
Dependent Claim
27 words
A coated seed as claimed in claim 6 wherein the caseinate salt is formed from an alkali metal, an alkaline earth metal, ammonia, or an organic amine.
Claim 10
Dependent Claim
17 words
A coated seed as claimed in claim 7 wherein the salt is formed from an alkali metal.
Claim 11
Dependent Claim
14 words
A coated seed as claimed in claim 8 wherein the alkali metal is potassium.
Claim 12
Dependent Claim
33 words
A coated seed as claimed in claim 6 wherein the caseinate salt is prepared as a solution having a caseinate salt concentration of from 10 to 20 percent by weight of the solution.
Claim 13
Dependent Claim
45 words
A coated seed as claimed in claim 10 wherein the caseinate salt solution is prepared by reacting casein with a salt forming agent in solution and adjusting the pH of the solution to between 6.5 and 7, and the solution is employed as the adhesive.
Claim 14
Dependent Claim
21 words
A coated seed as claimed in claim 5 wherein, after coating the seeds with the solution, the coated seeds are dried.
Claim 15
Dependent Claim
22 words
A coated seed as claimed in claim 11 wherein additional materials desired in the coating are incorporated in the caseinate salt solution.
Claim 16
Dependent Claim
19 words
A coated seed as claimed in claim 13 wherein a rhizobia inoculant is added to the caseinate salt solution.
Claim 17
Dependent Claim
21 words
A coated seed as claimed in claim 11 wherein, after coating the seeds with the solution, the coated seeds are dried.
Claim 18
Dependent Claim
21 words
A coated legume seed comprising a coating of rhizobia bacteria and lime bonded to the seed with an alkali metal caseinate.
Claim 19
Dependent Claim
21 words
A coated legume seed comprising a coating of rhizobia bacteria and lime bonded to the seed with an alkali metal caseinate.
