20140291151 | METHOD FOR PRODUCING SOLID OXIDE FUEL CELLS HAVING A CATHODE-ELECTROLYTE-ANODE UNIT BORNE BY A METAL SUBSTRATE, AND USE OF SAID SOLID OXIDE FUEL CELLS - The invention relates to a method of producing solid oxide fuel cells (SOFC) having a cathode-electrolyte-anode unit supported by a metal substrate. It is the object of the invention in this respect to provide solid oxide fuel cells which achieve an increased strength, improved temperature change resistance, a secure bonding of films forming the cathode-electrolyte-anode unit and can be produced free of distortion and reproducibly. In the method in accordance with the invention, a film forming the anode is first wet chemically applied to a surface of a porous metallic substrate as a carrier of the cathode-electrolyte-anode unit. An element which has already been sintered gas tight in advance and which forms the electrolyte is then placed on or applied a really to this film forming the anode and at a first thermal treatment up to a maximum temperature of 1250° C. the organic components contained in the film forming the anode are expelled, this film is sintered and in so doing a connection with material continuity is established between the substrate and the electrolyte. Subsequent to this, a further film forming the cathode is wet chemically applied to the electrolyte and is sintered in a further thermal treatment at temperatures beneath 1000° C. and the cathode is connected with material continuity to the electrolyte. | 10-02-2014 |
20150258533 | COMPONENT FOR HIGH-TEMPERATURE APPLICATIONS, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF - The invention relates to a component for high-temperature applications, to a method for the production thereof and to a use thereof. In this respect, an electrical conductivity and a catalytic effect should be achievable with a simultaneous chemical and thermal resistance under different conditions and also at temperatures above 700° C. The component in accordance with the invention is formed from a body which is formed from Ce1-x-yLnxMeyO2. In this respect, Ln is a rare earth metal and Me is a transition metal, where x=0.01 to 0.25 and y=0.05 to 0.2. Particles having a mean particle size in the range from 5 nm to 500 nm, preferably in the range from 10 nm to 300 nm, and formed using transition metal, are present in a distributed arrangement on at least one surface. | 09-17-2015 |

20160102456 | TRUSS ASSEMBLY - A metal truss assembly comprises a plurality of C-shape structural members including at least one chord member and two or more adjacent web members, each structural member having a base and two opposing flanges. The at least one C-shape chord member has flanges extending from each side of the base with one flange having cutouts to receive two C-shape web members with a part of said flange of said chord member in place between said cutouts. Each said C-shape web member is placed into one of the cutouts in said flange to intersect the at least one chord member with the bases of the two C-shape web members adjacent the base of the at least one chord member. | 04-14-2016 |

20140365469 | USER ADDRESS BOOK DATA MANAGEMENT SYSTEM - One or more techniques or systems are disclosed for allowing a first user to control what information is available to other users in the first user's address book on an address book system. A first user can import user contacts from one or more devices into the first user's address book in an address book system. The first user can enter additional contact information data into the first user's address book and edit preferences for other users to view selected portions of the entered contact information. The first user may subsequently identify a second user of the address book system and make a connection with the second user. The first user can edit access preferences for the second user, with regards to the second user accessing the first user's contact information. | 12-11-2014 |

20100294192 | BUOYANCY SYSTEM FOR AN UNDERWATER DEVICE AND ASSOCIATED METHODS FOR OPERATING THE SAME - A buoyancy system includes a chamber having a volume associated therewith, and bladders within the volume of the chamber. Each bladder contains a clathrate mixture in a liquid state. The chamber includes an opening to allow surrounding water to circulate within the volume and contact the bladders. As the chamber is submerged in the surrounding water, the bladders expand based on the clathrate mixture changing from the liquid state to a solid state. This changes buoyancy by allowing less water to circulate within the volume of the chamber. | 11-25-2010 |
20120015567 | OCEAN THERMAL BUOYANCY AND PROPULSION SYSTEM - A water navigable vessel or glider can transport cargo across oceans and other bodies of water without the use of fossil or nuclear fuels. The vessel includes a housing, a cargo or payload area within the housing, one or more control fins attached to the housing, a ballast within the housing, an expandable and contractible container configured to receive a clathrate and maintain a minimum amount of pressure on the clathrate within the housing in proximity to the ballast, and an intake valve coupled to the ballast. The clathrate changes state, thereby changing the buoyancy of the glider, and causing the glider to move through the body of water. | 01-19-2012 |
