Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
73 words
A COMPOSITION FOR PROTECTING STORED PLANT FEED-STUFFS AGAINST ATTACK BY MICRO-ORGANISMS WHICH COMPOSITION COMPRISES ABOUT 5 TO 80 PERCENT BY WEIGHT OF A HYDROCARBON MINERAL OIL WHICH HAS A DENSITY OF 15*C. OF 0.830 TO 1.025, A KINEMATIC VISCOSITY AT 50*C. OF 8 TO 600 CENTISTOKES, A PENSKY FLASH POINT OF 180* TO 300*C. AND AN ANILINE POINT OF -5* TO +120*C., AND ABOUT 95 TO 20 PERCENT BY WEIGHT OF PROPIONIC ACID.
Claim 2
Dependent Claim
73 words
A COMPOSITION FOR PROTECTING STORED PLANT FEED-STUFFS AGAINST ATTACK BY MICRO-ORGANISMS WHICH COMPOSITION COMPRISES ABOUT 5 TO 80 PERCENT BY WEIGHT OF A HYDROCARBON MINERAL OIL WHICH HAS A DENSITY OF 15*C. OF 0.830 TO 1.025, A KINEMATIC VISCOSITY AT 50*C. OF 8 TO 600 CENTISTOKES, A PENSKY FLASH POINT OF 180* TO 300*C. AND AN ANILINE POINT OF -5* TO +120*C., AND ABOUT 95 TO 20 PERCENT BY WEIGHT OF PROPIONIC ACID.
Claim 3
Dependent Claim
37 words
A composition as claimed in claim 1 in which the said composition consists essentially of 30 to 60 percent by weight of the said hydrocarbon mineral oil and 70 to 40 percent by weight of propionic acid.
Claim 4
Independent Claim
96 words
A method for treating plant feed-stuffs against attack by micro-organisms which method comprises spraying the plant feed-stuffs with an amount of 0.1 to 10 percent by weight based on the dry weight of the feed-stuffs of a composition comprising about 5 to 80 percent by weight of a hydrocarbon mineral oil which has a density at 15*C. of 0.830 to 1.025, a Kinematic Viscosity at 50*C. of 8 to 600 centistokes, a Pensky Flash Point of 180* to 300*C. and an aniline point of -5* to +120*C., and about 95 to 20 percent of propionic acid.
Claim 5
Independent Claim
96 words
A method for treating plant feed-stuffs against attack by micro-organisms which method comprises spraying the plant feed-stuffs with an amount of 0.1 to 10 percent by weight based on the dry weight of the feed-stuffs of a composition comprising about 5 to 80 percent by weight of a hydrocarbon mineral oil which has a density at 15*C. of 0.830 to 1.025, a Kinematic Viscosity at 50*C. of 8 to 600 centistokes, a Pensky Flash Point of 180* to 300*C. and an aniline point of -5* to +120*C., and about 95 to 20 percent of propionic acid.
Claim 6
Dependent Claim
33 words
A method as claimed in claim 3 in which the plant feed-stuffs are sprayed with 1 to 5 percent by weight, based on the dried weight of the feed-stuffs of the said composition.
