07/10/2014 > 2 patent applications in 2 patent subcategories.

20140193286 - Method and treatment element blank for the production of a treatment element for a screw machine: In a method for the production of a treatment element for a screw machine, a treatment element core of a first metal material is arranged in an inner space of a capsule of a hot isostatic pressing installation so that a contoured annular space is formed between a capsule wall... Agent:

20140193287 - Method of producing a shaped part: A shaped part that is particularly suited as an interconnector or an end plate for a fuel cell stack, is produced by pressing and sintering a pulverulent starting material. The shaped part has a basic body with a multiplicity of knob-like and/or ridge-like elevations with a height h. Each elevation... Agent:

07/03/2014 > 1 patent applications in 1 patent subcategories.

20140186205 - Method and apparatus for reconditioning oxidized powder: A metal powder reconditioning apparatus and method recondition contaminated residual powder from an additive manufacturing device. The apparatus and method include a reducing chamber that receives contaminated residual powder resulting from an additive manufacturing process and remove oxygen from the contaminated residual powder to produce reconditioned powder. The reconditioned powder... Agent: United Technologies Corporation

06/26/2014 > 2 patent applications in 2 patent subcategories.

20140178240 - Bearing forming method: A bearing forming method in which different properties of powder materials are compressed and molded in batches and then the materials are together sintered to form an integrated porous bearing. By means of the bearing forming method, the necessary material properties of a part of the bearing are enhanced. Moreover,... Agent: Asia Vital Components Co., Ltd.

20140178241 - Absorbed impurities reduction in additive manufacturing systems: A pulverant material supply system has an outer shell, an inner shell, and a plurality of openings to a passage within the inner shell to allow a reducing fluid into the pulverant material contained therein. The liner is made from a non-evaporable getter alloy.... Agent: United Technologies Corporation

06/19/2014 > 3 patent applications in 3 patent subcategories.

20140170012 - Additive manufacturing using partially sintered layers: The invention relates to an additive manufacturing apparatus and method. According to the invention, an additive manufacturing apparatus includes a material supply system. The material supply system delivers layers of partially sintered pulverant material to an additive manufacturing device.... Agent: United Technologies Corporation

20140170013 - In-situ combustion synthesis of titanium carbide (tic) reinforced aluminum matrix composite: An in-situ process for making aluminum titanium carbide composite materials include the steps of mixing powdered aluminum, titanium and calcium carbonate, compacting the mixture and heating by a high frequency induction heater up to a temperature at which titanium carbide is formed at about 800° C.-1,000° C. The compact are... Agent: King Saud University

20140170014 - Method for producing magnetic powder and magnet: Disclosed is a method for producing a magnetic powder comprising: a first step of producing a R—Fe—B-based rare earth isotropic magnetic powder using a scrap rare earth magnet through a HDDR process; and a second step of mixing the R—Fe—B-based rare earth isotropic magnetic powder with an anisotropic magnetic powder,... Agent: Hyundai Motor Company
