    • In a fluid mixing device calibration and complementary gases are supplied to constant flow devices (10, 12). The flows through devices (10, 12) are adjusted to be equal. The two gas flows are connected to switching valves (14, 16), which allow the gas flows to be either vented or fed to the frequency multiplier (18). The two valves (14, 16) are coupled to switch simultaneously but in opposite positions. Thus, the flow rate into the frequency multiplier (18) is constant but may be switched to comprise either calibration or complementary gas. The frequency multiplier divides the input stream into a number of equal streams which, after different time delays have been introduced, are recombined to produce a single stream of reduced concentration ripple and periodicity. The output from the frequency multiplier (18) fed to a series of chambers (20-24) where each chamber produces an attenuation of the concentration ripple and a time response to a change in concentration. As the attenuations of the chambers (20-24) are multiplicative and the time responses are additive, multiple chambers give a higher ratio of ripple attenuation to time response than does a single chamber. Better and faster production of substantially homogenised fluid mixtures is possible.
    • 在流体混合装置中,校准和补充气体被供应到恒流装置(10,12)。 流过设备(10,12)的流量被调整为相等。 两个气流连接到切换阀(14,16),这允许气流被排出或馈送到倍频器(18)。 两个阀(14,16)被联接以同时切换但在相对的位置。 因此,进入倍频器(18)的流量是恒定的,但可以被切换成包括校准或补充气体。 倍频器将输入流分成多个相等的流,其在引入不同的时间延迟之后被重新组合以产生降低的浓度波动和周期性的单个流。 来自倍增器(18)的输出被馈送到一系列室(20-24),其中每个室产生浓度波动的衰减和对浓度变化的时间响应。 由于室(20-24)的衰减是乘法的并且时间响应是相加的,所以多个室给出比单个室更高的纹波衰减与时间响应的比率。 更好和更快地生产基本均匀的流体混合物是可能的。

    • The tank-ventilating valve proposed has a housing (10) with inlet and outlet pipes (11, 12) between which an electromagnetically operated seat valve (31), biased in the valve-closure direction by a closure spring (49), is located. To ensure a simple valve design, the valve aperture is designed as a ring-gap nozzle (34) located in the magnet yoke (27) of the electromagnet (13), and the double valve seat (32) which acts together with the valve element (37) and surrounds the ring-gap nozzle (34), is located on the inlet-pipe (11) side of the magnet yoke (27). The hollow cylindrical core magnet (15) in the magnet housing (14) can be displaced by rotating a threaded adjustment element (19, 20) in the magnet housing (14), thus adjusting the stroke of the valve element (37). Resting against the core magnet (14) is a valve-closure spring (49) which biases the valve element (37), formed by the armature of the electromagnet (13), in the closure direction.
