| 20090280408 | NOVEL THIN FILM STRUCTURES - A thin film structure, method of producing it and the use thereof. The thin film structure comprises a substrate with a thin conductive layer containing an oxidizing enzyme mixed with an electron transfer mediator. The thin layer is protected against wetting to allow for its storage in dry conditions and further being sufficiently porous to allow for immediate activation of the oxidizing enzyme when contacted with an aqueous solution. The thin film can be used as a cathode in electrochemical fuel cells. | 11-12-2009 |

| 20090325884 | Method for Detecting Autoantibodies Formed in Rheumatoid Arthritis - Autoantibodies reacting against citrullinated peptides derived from C-telopeptides of type I and type II collagens are found in patients with rheumatoid arthritis. They detect sequences —YYXA from α1 or —FYXA from α2 chain of type I collagen or —YMXA from α1 chain of type II collagen, where X is citrulline. The antibodies are different from anti-filaggrin antibodies. The peptides of the invention can be used in diagnosis of rheumatoid arthritis. Oral administration of citrullinated peptides can induce tolerance and lead to the treatment of rheumatoid arthritis. | 12-31-2009 |

| 20110295529 | CONTROL OF PROTECTION RELAY - A protection relay and a method for controlling a protection relay are provided. An input parameter value is measured for the protection relay, and a calculation parameter value is determined based on an inverse definite minimum time curve defining a relationship between the input parameter value and a predetermined threshold value of the input parameter, wherein the calculation parameter values are divided into two or more zones and restricted with zone-specific dividers. The restricted calculation parameter value is added to a cumulative sum of the calculation parameter, where the cumulative sum of the calculation parameter is usable in a calculation equation for determining an operate and/or reset condition of the protection relay. | 12-01-2011 |

| 20080230527 | Method of manufacturing an exhaust gas manifold utilizing hybrid MIG welding - A method of manufacturing an exhaust gas manifold, that includes metal exhaust pipes and metal flanges for attaching the pipe openings to corresponding internal combustion engine exhaust ports, employs a hybrid MIG welding process to reduce the occurrences of weld spatter being deposited on the pipe surfaces. Additional benefits are a reduction in applied energy, a resultant reduction in heat being applied to the work pieces, less consumption of weld wire, and improved efficiency of making the weld on the inside surface of the flange adjacent to the pipe opening. The hybrid MIG technique involves moving the head of the weld gun so that its weld wire tip is in contact with the closed path joint formed between an aperture in the flange and the pipe opening. Electrical energy is then applied between the weld wire and the work pieces (flange and pipe) for a relatively short period of time that is sufficient to cause the tip of the weld wire to become a molten drop. When the molten weld material is formed, the application of electrical energy is terminated and the weld wire is retracted or withdrawn away from contact to allow the molten wire drop to enter the joint and form the weld. The weld head is then moved with respect to its current location with respect to the work piece and the weld steps are repeated at a predetermined rate at each point along the joint to complete the weld between the pipe opening and the flange. | 09-25-2008 |
