    • Devices and methods are provided to enhance magnetic field communication. One aspect of the present subject matter relates to a method for transmitting and receiving signals using an antenna element electrically connected to a driver and an amplifier. According to various embodiments of the method, a first signal is transmitted from the antenna element and a second signal that was induced in the antenna element is received. Transmitting the first signal includes driving the first signal through the antenna element using the driver, and monitoring the first signal through an input impedance of the amplifier. Receiving the second signal includes reducing the input impedance of the amplifier, and receiving the second signal at the amplifier through the reduced input impedance. Various embodiments shield the antenna element from electric and electromagnetic fields. Other aspects are provided herein.

    • A process for the production of a uranium oxide in which UF.sub.6 is converted by reaction with steam into UO.sub.2 F.sub.2 in a first step and by further reaction of UO.sub.2 F.sub.2 with steam and/or hydrogen in a second step to produce an oxide of uranium, the process being carried out in an apparatus comprising a single kiln vessel having a first region, having UF.sub.6 and steam inlets, wherein the fast step may be carried out, and a second region wherein the said second step may be carried out, which process includes the further steps of analysing the oxide of uranium produced to determine the mount of fluoride present and the oxygen to uranium (O/U) ratio therein, and, where the level of fluoride present is unacceptably high, recycling the oxide of uranium to the said second region to produce an oxide of uranium having a lower fluoride content and oxygen to uranium ratio and wherein the said oxide of uranium having the unacceptably high fluoride content is fed into the first region of the vessel, in the absence of any feeding of UF.sub.6 or steam thereto, and conveyed by conveying means directly into the second region of the vessel.

    • A system and humidity control method is provided for a multi-stage cooling system having two or more refrigerant circuits that balances humidity control and cooling demand. Each refrigerant circuit includes a compressor, a vessel and an evaporator. A hot gas reheat circuit having a heat exchange coil is connected to one of the refrigerant circuits and is placed in fluid communication with the output airflow from the evaporator of that refrigerant circuit to provide additional dehumidification to the air when humidity control is requested. The hot gas reheat circuit bypasses the vessel of the refrigerant circuit during humidity control. Humidity control is performed during cooling operations and ventilation operations. During a first stage cooling operation using only one refrigerant circuit and having a low cooling demand, the request for humidity control activates the hot gas reheat circuit for dehumidification and activates a second refrigerant circuit to provide cooling capacity. The hot gas reheat circuit is sized to match the cooling provided by the evaporator so that air cooled by passing through the evaporator can be reheated. Excess refrigerant is passed into the inactive cooling circuit so that proper pressure and temperature can be maintained in the active reheat circuit and so that high head pressure that can damage the compressor can be avoided. During a second stage cooling operation using two or more refrigerant circuit and having a high cooling demand, the request for humidity control is suspended and is initiated only upon the completion of the second stage cooling demand.
    • 为具有平衡湿度控制和冷却需求的两个或多个制冷剂回路的多级冷却系统提供一种系统和湿度控制方法。 每个制冷剂回路包括压缩机,容器和蒸发器。 具有热交换线圈的热气体再热回路连接到一个制冷剂回路,并且与来自该制冷剂回路的蒸发器的输出气流流体连通,以便在要求湿度控制时向空气提供额外的除湿。 湿气再热回路在湿度控制期间绕过制冷剂回路的容器。 在冷却操作和通风操作期间进行湿度控制。 在仅使用一个制冷剂回路并且具有低冷却需求的第一阶段制冷操作期间,对湿度控制的请求激活用于除湿的热气再热回路,并且启动第二制冷剂回路以提供冷却能力。 热气体再热回路的尺寸与蒸发器所提供的冷却相匹配,使得通过蒸发器冷却的空气可被再加热。 过量制冷剂进入惰性冷却回路,从而可以在主动再热回路中保持适当的压力和温度,从而可以避免可能损坏压缩机的高压头。 在使用两个或更多个制冷剂回路并具有高冷却需求的第二阶段制冷操作期间,停止对湿度控制的请求,并且仅在第二阶段冷却需求完成时启动。
