Patent number: 10843451Abstract: A nozzle system and method of manufacturing a nozzle system for use in an additive manufacturing system for fabricating an object is disclosed. The nozzle system includes a monolithic nozzle head designed such that the thermal locking member, neck member, and nozzle member of the nozzle head are manufactured into one component. The nozzle head is made of a material that has a high specific heat capacity but low thermal heat conductivity. The result is a nozzle system design that virtually eliminates heat migration from the nozzle head to the heat sink, and thereby improves the overall quality of polymer filament deposition during printing.Type: GrantFiled: March 30, 2020Date of Patent: November 24, 2020Assignee: Cosine Additive Inc.Inventors: Jason Miller, Andrew McCalip

Patent number: 10836086Abstract: An injection molding apparatus includes a first upstream mold having a first gate opening into which a first molding material flows, a second upstream mold having a second gate opening into which a second molding material flows, a first injection unit injecting the first material through the first gate opening, a second injection unit injecting the second material through the second gate opening, and a downstream mold clampable with each of the first and second upstream molds. The second material is injected by the second injection unit after the first material is injected by the first injection unit. The second gate opening is separated further from the downstream mold than the first gate opening, and a volume of a second cavity partitioned by the second upstream mold and the downstream mold is larger than that of a first cavity partitioned by the first upstream mold and the downstream mold.Type: GrantFiled: August 19, 2019Date of Patent: November 17, 2020Inventors: Yusuke Watanabe, Kenta Anegawa, Seiichiro Yamashita, Kei Yokota, Yuichi Sasage, Kakeru Sasagawa

Patent number: 10837704Abstract: A method for repairing a refractory lining of a metallurgical vessel in the hot state. This repair takes place using a supplying apparatus. In addition, recording of at least the worn regions and monitoring of the repair are carried out by a monitoring device. Before, during and/or after the supplying of material, at least a partial region of the areas of the refractory lining of the vessel or the gunning jet is recorded photographically with visualization of the temperature ranges. This results in an evaluation with regard to different parameters such as properties, layer thickness and/or distribution of the supplied material. It has been demonstrated that visualization of the temperature ranges of the areas to be repaired and of the refractory material during supplying of material enables different parameters to be established very accurately, and as a result, optimal coating of the wall lining can be achieved.Type: GrantFiled: May 13, 2016Date of Patent: November 17, 2020Assignee: Refractory Intellectual Property GmbH & Co. KGInventors: Gregor Lammer, Alexander Cepak
