Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
80 words
A PAN RELEASE PRODUCT COMPRISING A MECHANICAL ATOMIZER CONTAINING AN AQUEOUS SUSPENSION OF AN ACYLATED, HYDROXYLATED LECITHIN, ALL OF SAID LECITHIN BEING BOTH ACYLATED AND HYDROXYLATED, SAID ACYLATION BEING CARRIED OUT TO REDUCE THE FREE AMINO NITROGEN VALUE FROM ABOUT 10% TO ABOUT 90% RELATIVE TO CRUDE LECITHIN, SAID HYDROXYLATION BEING CARRIED OUT WITH AT LEAST 1% HYDROGEN PEROXIDE BY WEIGHT OF THE UNMODIFIED LECITHIN TO REDUCE THE IODINE VALUE FROM ABOUT 5% TO ABOUT 20% RELATIVE TO CRUDE LECITHIN.
Claim 2
Dependent Claim
80 words
A PAN RELEASE PRODUCT COMPRISING A MECHANICAL ATOMIZER CONTAINING AN AQUEOUS SUSPENSION OF AN ACYLATED, HYDROXYLATED LECITHIN, ALL OF SAID LECITHIN BEING BOTH ACYLATED AND HYDROXYLATED, SAID ACYLATION BEING CARRIED OUT TO REDUCE THE FREE AMINO NITROGEN VALUE FROM ABOUT 10% TO ABOUT 90% RELATIVE TO CRUDE LECITHIN, SAID HYDROXYLATION BEING CARRIED OUT WITH AT LEAST 1% HYDROGEN PEROXIDE BY WEIGHT OF THE UNMODIFIED LECITHIN TO REDUCE THE IODINE VALUE FROM ABOUT 5% TO ABOUT 20% RELATIVE TO CRUDE LECITHIN.
Claim 3
Dependent Claim
21 words
The product of claim 1 in which the proportion of lecithin in the aqueous suspension is in the range of 1%-25%.
Claim 4
Dependent Claim
14 words
The product of claim 2 in which the range is between 10 and 12%.
Claim 5
Independent Claim
46 words
A method of coating a vessel with a release coating comprising the steps of dispersing from about 10 to 25% of an acylated, hydroxylated, neutralized lecithin having mechanically atomizing the dispersion thus achieved onto a warmed cooking surface to flash evaporate the water in said dispersion.
Claim 6
Independent Claim
46 words
A method of coating a vessel with a release coating comprising the steps of dispersing from about 10 to 25% of an acylated, hydroxylated, neutralized lecithin having mechanically atomizing the dispersion thus achieved onto a warmed cooking surface to flash evaporate the water in said dispersion.
Claim 7
Dependent Claim
16 words
The method of claim 4 in which the concentration of lecithin is between 10 and 12%.
