    • This invention relates to valve assemblies and particularly to valve assemblies adapted to prevent backflow which also incorporate an atmospheric vacuum breaker. The most basic arrangement involves a vacuum breaker device (16, 28) which comprises an integral non-return valve located upstream of a user operable valve control means (21) wherein the non-return valve of the vacuum breaker device is biased to close against the flow of fluid from the supply (Fig. 14). The second of these variations shows a vacuum breaker device comprising an integral non-return valve located upstream of the valve assembly outlet wherein the non-return valve is biased closed but which is limited in its movement to allow flow of fluid through the valve assembly by a user operable valve control means (Fig. 7). The third of these variations comprises the addition of a second non-return valve (17) upstream of the vacuum breaker device (Fig. 13). The fourth of these arrangements is conceptually identical to the third arrangement but offers an alternative construction (Fig. 12). The fifth of these arrangements shows a vacuum breaker device upstream of the valve assembly outlet and a second non-return valve further downstream wherein the second non-return valve is biased closed to allow flow through the valve assembly by a user operable valve control means (Fig. 16). Other arrangements for a ball valve (Fig. 22) and various bib-cocks (Figs. 23-34) are also described.
    • 本发明涉及阀组件,特别涉及适于防止也包括大气真空断路器的回流的阀组件。 最基本的布置包括真空断路器装置(16,28),其包括位于用户可操作的阀控制装置(21)的上游的整体止回阀,其中真空断路器装置的止回阀被偏压以抵靠 来自电源的流体流动(图14)。 这些变型中的第二个示出了真空断路器装置,其包括位于阀组件出口上游的整体止回阀,其中止回阀被偏压关闭,但是其运动受到限制,以允许流体通过阀组件流过阀组件 用户可操作的阀控制装置(图7)。 这些变化中的第三个包括在真空断路器装置上游添加第二止回阀(17)(图13)。 这些布置中的第四种在概念上与第三种布置相同,但是提供了另一种构造(图12)。 这些布置中的第五个示出了在阀组件出口上游的真空断路器装置和进一步下游的第二止回阀,其中第二止回阀被偏压关闭以允许通过用户可操作的阀控制装置 图16)。 还描述了球阀(图22)和各种双头旋塞(图23-34)的其它布置。

    • A video sequence control system 100 is described that includes a switching component 102 coupled to a video source and a switch control signal 108. The video source 110 produces analog video signals representative of a sequence of input image video frames. The switching component 102 switches between analog video signals representative of at least input image video frames and crosstalk reduction frames. Switching from an input image video frame type to a crosstalk reduction frame type requires switching the voltage values of the analog video signals representative of the input image video frame to a voltage signal representative of the crosstalk reduction frame type. A video frame sequence control component 104 provides video frame output sequence information including timing information and sequence information of the video frame to be output by the switching component 102.
