    • The disclosure relates to a method for discovery of one or more devices of a group of devices to establish a direct connection between at least two devices of the group of devices over a wide area network. The wide area network contains or is connected to a discovery server system. The discovery server system is configured for identifying a group associated with the group of devices, wherein each of the devices has a corresponding device identifier associated with the group. A discovery message from a first device of the group of devices is received, the discovery message comprising a device identifier associated with the first device. The group associated with the group of devices is determined on the basis of the received device identifier of the first device. The corresponding device identifier of one or more devices of the group of devices is determined on the basis of the determined group, and discovery information is transmitted only to one or more devices of the group of devices.
    • 本公开涉及一种用于发现一组设备的一个或多个设备以在广域网上建立该组设备的至少两个设备之间的直接连接的方法。 广域网包含或连接到发现服务器系统。 发现服务器系统被配置用于识别与该组设备相关联的组,其中每个设备具有与组相关联的相应设备标识符。 接收来自该组设备的第一设备的发现消息,该发现消息包括与第一设备相关联的设备标识符。 基于所接收到的第一设备的设备标识来确定与设备组相关联的组。 基于所确定的组确定该组设备中的一个或多个设备的相应设备标识符,并且发现信息仅被发送到该组设备的一个或多个设备。

    • The invention provides a process for preparing a metal hydroxide comprising the steps of: (a) providing particles of a metal silicate; (b) mixing the particles with a mineral acid solution to obtain a slurry which comprises precipitated silica; (c) separating the precipitated silica from the slurry to obtain a remaining solution; (d) increasing the pH of the remaining solution to such an extent that a metal hydroxide is formed; (e) separating the metal hydroxide so obtained from the remaining solution; and (f) adding to the remaining solution obtained in step (e) an acid solution, thereby forming a salt containing solution, or (g) removing at least part of the base added in step (d) from the remaining solution obtained in step (e), thereby forming a salt containing solution.
    • 本发明提供一种制备金属氢氧化物的方法,包括以下步骤:(a)提供金属硅酸盐的颗粒; (b)将所述颗粒与无机酸溶液混合以获得包含沉淀二氧化硅的浆料; (c)从沉淀物中分离沉淀的二氧化硅以获得剩余的溶液; (d)将剩余溶液的pH提高到形成金属氢氧化物的程度; (e)将从所得剩余溶液中得到的金属氢氧化物分离; 和(f)向步骤(e)获得的剩余溶液中加入酸溶液,从而形成含盐溶液,或(g)从步骤(d)中获得的剩余溶液中除去步骤(d)中加入的至少一部分碱 (e),从而形成含盐溶液。
