Title: Soluble keratin peptide
Inventor: BLANCHARD CHERYL R
IPC: A61K38/17
Filed: 2000-06-09
Abstract: 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 fo r a time and temperature sufficient to swell the keratin and oxidize some of t he 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, a nd the precipitate collected and dried to form the wound-healing agent. The wou nd- 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.

Patent CA-2382685-A1 (CA)
Inventor: LUNDBERG EGIL
IPC: C25C7/02
Filed: 2000-09-08
Abstract: The present invention concerns an improved carbon electrode and a method for  producing such a carbon electrode. In particular, the present invention relates to anodes for use in connection with electrolytic production of aluminium in accordance with the Hall-Héroult process. The anisotropy in a vibrated carbon anode results in partially significant differences in the physical properties depending on how the samples are oriented in relation to  the vibration direction, in particular with regard to electrical resistance.  For a tested, typical quality electrode, the resistance perpendicular to the  vibration direction is 8.3 % lower than in the vibration direction. If this is utilised by placing the nipple or suspension hanger holes so that the direction of electric current flow when the electrode is in use in the electrolysis is substantially 90~ to the vibration/compression direction, th is can produce a reduction of approximately 0.31 % in power consumption.</SDOAB >

Patent CA-2394911-A1 (CA)
Inventor: PIERONI KENNETH A
IPC: G01M3/22
Filed: 2002-07-24
Abstract: A method for detecting leaks in a fluid system that is located at a volatile and potentially explosive environment such as, but not limited to, the evaporative or air brake system of a motor vehicle. A smoke generating machine (1) produces a supply of smoke (30) to be delivered to the system under test (50). At least some of a mixture (8) of oil and fluorescent dye is heated and vaporized into smoke within a sealed chamber (2). The mixture is blown against a heating element (14) within the sealed chamber (2) by means of non-combustible nitrogen gas (28) so as to avoid the possibility of an explosion. The smoke (30) functions as a carrier for the dye. Some of the smoke (30) which is delivered to the system under test (30) from the chamber (2) will exit a leak (e.g. a hole 52), and the fluorescent dye carried by the smoke will leave a fluorescent trace (54) around the leak. By shining ultraviolet light (58) along the system under test (50), the fluorescent trace (54) around the leak (52) will be illuminated. Accordingly, even small leaks may be quickly, easily and reliably located for repair.
