Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
48 words
The process of feeding larval marine animals, comprising the step of adding to the aqueous support system of the larval marine animals water-stable, substantially homogeneous, microglobules of hydrophilic, polymeric, cross-linked, film-forming material, having oil-insoluble nutrient material dispersed therein, and having a diameter of about 1 to 1000 microns.
Claim 2
Dependent Claim
48 words
The process of feeding larval marine animals, comprising the step of adding to the aqueous support system of the larval marine animals water-stable, substantially homogeneous, microglobules of hydrophilic, polymeric, cross-linked, film-forming material, having oil-insoluble nutrient material dispersed therein, and having a diameter of about 1 to 1000 microns.
Claim 3
Dependent Claim
105 words
The process of claim 1 wherein the microglobules have been prepared by a process comprising the steps of: (A) Providing a continuous-phase vehicle material of water-immiscible liquid; (B) Providing a discontinuous phase of solid material as discrete, minute particles, dispersed in said continuous phase vehicle material, wherein said discontinuous phase material consists substantially of hydrophilic polymeric cross-linkable film-forming material having oil-insoluble nutrient material dispersed therein; (C) Subsequently adding a liquid water-soluble cross-linking agent, with agitation, to the dispersion of discontinuous phase particles and the continuous-phase vehicle to harden the discontinuous-phase particles and form stable, substantially homogenous microglobules thereof of about 1 to 1000 micron size.
Claim 4
Dependent Claim
18 words
The process of claim 2 wherein the hydrophilic polymeric material is gelatin and the cross-linking agent is glutaraldehyde.
