Publication number: 20230399718Abstract: A method and system for recovering a high yield of low carbon ferrochrome metal from chromite ore and low carbon ferrochrome metal produced by the method. A thermochemistry calculated mixture of feed materials including aluminum granules, burnt limestone, and chromite ore are provided into a DC plasma arc furnace. The aluminum granules are produced from aluminum scrap. The feed materials are heated upon entering the furnace free board through a feed mix injection system, whereupon the aluminum in the aluminum granules produces an exothermic reaction reducing the chromium oxide and iron oxides in the chromite ore to produce molten low carbon ferrochrome metal with molten slag floating thereon. The molten low carbon ferrochrome metal is extracted, solidified into ingots, crushed into coarse pieces or fines of low carbon ferrochrome metal product. The molten slag is extracted, quenched and solidified into slag particles product.Type: ApplicationFiled: August 2, 2023Publication date: December 14, 2023Inventors: Daniel Shaw, Adriaan Jacobus Van Der Merwe, Ottmar Aloys Lange

Patent number: 10757173Abstract: A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor.Type: GrantFiled: October 5, 2017Date of Patent: August 25, 2020Assignee: AT&T Intellectual Property I, L.P.Inventors: Jacobus Van der Merwe, Seungjoon Lee, Oliver Spatscheck

Patent number: 10069799Abstract: Methods and apparatus to configure virtual private mobile networks are disclosed. Example methods include provisioning a virtual private mobile network within a wireless network, and, after provisioning the virtual private mobile network, determining whether a first communication from a user equipment matches a security event profile. When the first communication matches the profile, the example methods include transmitting, from the wireless network via a first base transceiver station, an instruction to cause the user equipment to be communicatively coupled to the virtual private mobile network. The example methods further include instructing the user equipment to transmit a second communication through a second base transceiver station that is physically separate from the first base transceiver station and through the virtual private mobile network. In the example methods, the virtual private mobile network is isolated in a wireless spectrum from other portions of the network.Type: GrantFiled: June 27, 2016Date of Patent: September 4, 2018Assignee: AT&T Intellectual Property I, L.P.Inventors: Arati Baliga, Xu Chen, Baris Coskun, Gustavo de los Reyes, Seungjoon Lee, Suhas Mathur, Jacobus Van der Merwe, Gang Xu
