Abstract
Abstract HERBERT H. BECK DONALD G. ROBINSON METHOD FOR IMPROVING PIPELINE TRANSMISSION CHARACTERISTICS OF AQUEOUS SLURRIES OF NON-ARGILLACEOUS MINERALS ABSTRACT OF THE DISCLOSURE Aqueous slurries of non-argillaceous minerals can be more efficiently transmitted through pipelines by adding directly to such slurries while they are being pumped through pipelines water-in-oil emulsions of water-soluble vinyl addition polymers.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
63 words
A method for improving the pipeline transmission characteristics of aqueous slurries of non-argillaceous minerals which comprise adding directly to said slurries while they are being transported in pipelines a water-in-oil emulsion which contains distributed therein a finely divided water-soluble vinyl addition polymer in an amount sufficient to provide at least 0.001% by weight of said polymers based on the weight of said slurries.
Claim 2
Independent Claim
63 words
A method for improving the pipeline transmission characteristics of aqueous slurries of non-argillaceous minerals which comprise adding directly to said slurries while they are being transported in pipelines a water-in-oil emulsion which contains distributed therein a finely divided water-soluble vinyl addition polymer in an amount sufficient to provide at least 0.001% by weight of said polymers based on the weight of said slurries.
Claim 3
Dependent Claim
15 words
The method of Claim 1 where the water-soluble vinyl addition polymer is an acrylamide polymer.
Claim 4
Dependent Claim
17 words
The method of Claim 2 where the acrylamide polymer is a copolymer of acrylamide and acrylic acid.
