摘要: This invention relates to a method for producing chromates, especially for producing alkali metal chromates. The method comprises following steps: the obtaining of a mixture of alkali metal hydroxide, alkali metal chromate, and ferrous residue after the reaction of chromite ore with an oxidant in the reactor in the presence of molten salt or in aqueous solution of alkali metal hydroxide, the obtaining of a leaching slurry by leaching the reaction products with aqueous solution of alkali metal hydroxide, the separating of the primary chromate product from the leaching slurry, the obtaining of pure chromate crystal by purifying the primary chromate product. Both the primary chromate product and the pure chromate crystal can be used as the raw materials to manufacture other chromium compounds. Compared with the currently-used roasting method, the method has the advantages of decreasing the reaction temperature by about 700° C., of improving the chromium recovery rate up to nearly 100%, of minimizing the amount of the ferrous residue by not adding calcium-containing auxiliaries, and of completely eliminating the disposal problem of the chromium-containing residue and the environmental pollution due to the addition of calcium-containing auxiliaries, by using ferrous residue as the raw materials for other industries after extraction of magnesium.

摘要: System and techniques for base station assisted Information Centric Network (ICN) are described herein. A mobile network base station receives an ICN packet from a user equipment (UE). The mobile network base station identifies an aggregate packet data unit (PDU) session with a user plane function (UPF) ICN gateway (ICN-GW) hosted in a mobile network core network (CN) for the ICN packet. Then, the mobile network base station transmits the ICN packet via the aggregate PDU session.

摘要: This disclosure describes systems, methods, and devices related to latency reduction. The device may set up a plurality of links between an access point (AP) multi-link device (MLD) and a non-AP MLD. The device may encode a frame for transmission on a first link of the plurality of links between a first AP of the AP MLD and a first STA of the non-AP MLD. The device may identify an indication received at a second STA of the non-AP MLD using an interference mitigation signal. The device may cause to stop the transmission of the frame on the first link based on the indication. The device may identify a second frame on the first link received from the first AP. The device may cause to resume the transmission of the first frame on the first link.

摘要: An antenna includes a metal tube, a coaxial cable disposed along a central axis of the metal tube, and a variable-impedance transmission wire structure. A dielectric body and a metal part are arranged along an axial direction of the cable. The antenna makes the resulting structure stable and reliable, achieves miniaturization of a multi-band antenna and provides a sufficiently wide bandwidth for each frequency band. The antenna also realizes easy control of the radiation pattern and is convenient for practical applications.

摘要: Systems and techniques for mission critical (MC) push notification mechanism in a high-reliability (HR) information centric network (ICN) are described herein. For example, a node may test network links to other nodes to classify the other nodes into proximate nodes and non-proximate nodes based on a reception metric. The node may then elect a set of leader nodes from the proximate nodes. Here, the set of leader nodes are selected based on link quality between respective leader nodes and non-proximate nodes. The node may detect an MC event and create an ICN data packet that contains data from the MC event. The node may then transmit the ICN data packet to the set of leader nodes that then relay the ICN data packet to the non-proximate nodes.

摘要: Methods and apparatuses for controlling a handover of a device communicating via coexisting radios separated in time. It is determined whether to continue the communications via the coexisting radios during the handover and information is signaled to the device regarding communications via the coexisting radios based on the determination. The determination can include negotiations between a source and a target station. The source and/or the target station may determine whether to continue the communications via the coexisting radios during the handover, and selectively signaling information regarding communications during the handover via the coexisting radios based on the determination. The device, upon receiving signaling containing information whether to continue the communications via the coexisting radios during handover, processes the handover and selectively communicates via at least one of the coexisting radios during the handover based on the information.
