Patent number: 6239183Abstract: A method for controlling the rheology of aqueous systems, particularly for those intended for underground use, includes injecting an aqueous fluid containing a surfactant gelling agent into the system. The surfactant gelling agents are, for example, fatty aliphatic amidoamine oxides, salts of an alkoxylated monoamine with an aromatic dicarboxylic acid, and salts of an alkyldiamine with an aromatic dicarboxylic acid. The surfactant gelling agents can be adsorbed onto particulate supports to facilitate delivery of the gelling agent. The additives may be incorporated in the viscoelastic fluid to tailor its use in hydraulic fluids, drilling muds, fracture fluids, and in applications such as permeability modification, gravel packing, cementing, and the like.Type: GrantFiled: December 19, 1997Date of Patent: May 29, 2001Assignee: Akzo Nobel NVInventors: Robert F. Farmer, Andress K. Doyle, Glenda Del Carmen Vale, James F. Gadberry, Michael D. Hoey, Randy E. Dobson

Patent number: 5089160Abstract: A packaged aerosol preparation is provided for use in removing lint, hair and other particulate matter from fabrics. The sprayable liquid composition is packaged in a valve-equipped aerosol container. The composition includes an acrylic polymer or copolymer resin, a tackifier or plasticizer, and a liquified propellant consisting of either dimethyl ether or a mixture of dimethyl ether with a hydrocarbon propellant. The composition can be applied to absorbent substrates such as paper towels to provide an effective, disposable removal device.Type: GrantFiled: October 16, 1989Date of Patent: February 18, 1992Assignee: Alberto-Culver CompanyInventors: Thomas J.

Patent number: 4990192Abstract: A novel method is provided for removing lint, hair, and other particulate matter from fabric articles such as clothing, upholstery, or draperies. A sprayable aerosol adhesive composition is applied to flexible sheet material, such as a paper towel, so as to splatter the surface of the sheet with tacky adherent globules of a tackified or plasticized resin without forming a continuous coating on the surface. The sprayed surface of the sheet is ready within 60 seconds for contacting with the fabric from which the particulate matter is to be removed.Type: GrantFiled: October 16, 1989Date of Patent: February 5, 1991Assignee: Alberto-Culver CompanyInventors: Thomas J.

Patent number: 4049608Abstract: Novel copolymerizable esters of cinnamic acid or an .omega.-alkenoic acid of from 4 to 18 carbon atoms, such as undecylenic acid, with certain hydroxyalkane sulfonic acids, such as isethionic acid, are described together with processes of making them and copolymers thereof.
