Patent number: 7597016Abstract: A method of using an exhaust flow simulation system to test the effects of exhaust system conditions on various materials. A typical exhaust flow simulator is a burner-based system, in which exhaust from burner combustion is exhausted through an exhaust line. A “test coupon” of the material may be placed at an appropriate location in the flow line, and tested to determine how it is affected by the exhaust resulting from various fuels and additives.Type: GrantFiled: November 3, 2006Date of Patent: October 6, 2009Assignee: Southwest Research InstituteInventors: Suzanne A. Timmons, Scott F. Timmons

Patent number: 6849092Abstract: A keratin hydrogel-filled implantable prosthetic device. One device is a breast implant for augmenting or reconstructing a human breast including an envelope containing a keratin hydrogel. One keratin hydrogel is formed from a solid precursor which forms a keratin hydrogel upon addition of water. One source of keratin is human hair. In one method, an envelope suitable for implantation and a solid keratin hydrogel precursor are provided. The solid can be in fibrous or powder form. The solid precursor can be inserted into the envelope interior. A small incision near the breast can be made and the envelope inserted into the incision. After insertion, water can be injected into the envelope interior, preferably through the incision and through a self-sealing port in the envelope. In one method, the implant is provided as a kit, with the envelope and keratin hydrogel provided. The hydrogel can be injected into the envelope either before or after insertion into the breast area.Type: GrantFiled: March 8, 2001Date of Patent: February 1, 2005Assignee: Keraplast Technologies, Ltd.Inventors: Mark E.

Publication number: 20040076599Abstract: A hydratable, highly absorbent keratin solid fiber or powder capable of absorbing a large weight excess of water may be produced by partially oxidizing hair keratin disulfide bonds to sulfonic acid residues and reacting the sulfonic acid residues with a cation. The neutralized suspension can be filtered, washed, and dried, leaving keratin solid which can be shredded into fibers and further ground into powder. Addition of water to the solid produces a hydrogel. The powder or hydrogel may be useful as an absorbent material, as a therapeutic for skin, or as an excipient.

Publication number: 20030035820Abstract: Methods for producing thin keratin films, sheets, and bulk materials, and products formed using these methods. One method includes providing hair, reducing the hair such that the disulfide linkages are broken and free cysteine thiol groups formed, separating out a more soluble keratin fraction in solution, forming a thin layer from the more soluble fraction, and air drying the keratin fraction in the presence of oxygen, thereby forming new disulfide bonds imparting strength to the resulting thin keratin film. One method includes reducing hair by heating the hair under nitrogen in an ammonium hydroxide and ammonium thioglycolate solution followed by centrifuging and collecting the supernatant containing the more soluble keratin fraction. The more soluble keratin in this method is precipitated using HCI, removed, and resuspended in ammonium hydroxide. The keratin solution thus formed is poured onto a flat surface and allowed to air dry into a thin keratin film.Type: ApplicationFiled: August 13, 2002Publication date: February 20, 2003Applicant: Southwest Research Institute and Keraplast Technologies, Ltd.Inventors: Scott F.

Patent number: 6379690Abstract: A keratin hydrogel which can be used as a wound dressing and cell scaffolding. The keratin hydrogel is formed from clean, washed hair by partially oxidizing a significant percentage of disulfide linkages to form cysteic acid groups, while some disulfide linkages remain intact. The partially oxidized hair is treated with a reducing agent, thereby reducing most of the remaining disulfide linkages to cysteine-thioglycollate disulfide and cysteine groups. A soluble fraction of hair is collected and oxidized, such that the reduced sulfur groups are allowed to reform disulfide linkages, thereby binding the keratin together. The cysteic acid groups remain, providing hydrophilic sites within the hydrogel. A higher degree of partial oxidation results in a greater abundance of hydrophilic cysteic acid groups in the hydrogel.Type: GrantFiled: December 12, 2000Date of Patent: April 30, 2002Assignee: Keraplast Technologies, Ltd.Inventors: Cheryl R.

Publication number: 20010047082Abstract: A peptide derived from keratin, which can be used as a wound-healing agent. In one method for making the peptide, a keratin source such as human hair is washed, dried, and treated with an oxidizing agent such as peracetic acid for a time and temperature sufficient to swell the keratin and oxidize some of the disulfide bonds to form sulfonic acid groups. The oxidation is believed to form a series of water-soluble peptides. The oxidized hair can be filtered, and the filtrate collected and concentrated under vacuum distillation to a viscous syrup, which can be neutralized with base. The concentrate can be mixed with an excess of a water-miscible organic solvent such as methanol, and the precipitate collected and dried to form the wound-healing agent. The wound-healing agent is believed to include peptides having a molecular weight centered around 850 daltons and having at least one ionizeable group such as sulfonic acid.Type: ApplicationFiled: July 2, 2001Publication date: November 29, 2001Inventors: Mark E.
