摘要： ABSTRACT The invention discloses an overshot control gate (26) for use with trapezoidal irrigation channels (10). Gate (26) has a rigid rectangular section (38) adapted to, in use, be pivotally mounted to the base (12) of trapezoidal irrigation channel (10). A pair of triangular sections are pivotally mounted on opposite sides (60, 62) of the rigid rectangular section (38). Each of the triangular sections being divided into first and second triangular sections (44, 46, 52, 54) with a common apex (70, 72) at the base (12) of the trapezoidal irrigation channel (10). Each of the first triangular sections (44, 46) being rigid and adapted to, in use, be pivotally mounted (48, 50) to opposite side walls (14, 16) of trapezoidal irrigation channel (10). Each of the second triangular sections 52, 54) including the pivotal mounting on opposite sides (60, 62) of rectangular section (38) and being formed of a flexible material. Also disclosed is a pipe flow meter (210) and a duckbill valve (200).

摘要： A fluid control barrier (70) for a pipe (74) including
a bi-foldable barrier member (82, 84, 86) for controlling movement of fluid along the pipe and having a pair of plates (82, 84) with a hinge (86) along their straight edges to allow for opening and closing of said fluid control barrier; and
an actuation mechanism including
a threaded screw member (122) having a first thread (128) and a second thread (130);
a pair of threaded journals (138, 140);
a first pair of struts (142, 146) and another pair of struts (144, 148);
the pair of plates including a first plate (82) and a second plate (84);
the first thread opposing the second thread;
the pair of threaded journals including
a first threaded journal (138) threadingly engaged with the first thread and constrained from rotating;and
a second threaded journal (140) threadingly engaged with the second thread and constrained from rotating;
the first pair of struts connecting the threaded journals to the first plate, and the second pair of struts connecting the threaded journals to the second plate, such that rotating the threaded screw member opens and closes the bi-foldable barrier member.摘要翻译： 1。一种用于管道（74）的流体控制屏障（70），所述管道包括用于控制沿着所述管道的流体移动的双折叠屏障构件（82,84,86）并且具有一对具有铰链的板（82,84） 沿着它们的直边，以允许打开和关闭所述流体控制屏障; 以及包括具有第一螺纹（128）和第二螺纹（130）的螺纹螺纹构件（122）的致动机构; 一对带螺纹的轴颈（138,140）; 第一对支柱（142,146）和另一对支柱（144,148）;第二对支柱 所述一对板包括第一板（82）和第二板（84）; 第一线与第二线相对; 所述一对螺纹轴颈包括与所述第一螺纹螺纹接合并且被限制旋转的第一螺纹轴颈（138）;以及与所述第二螺纹螺纹接合并且被限制旋转的第二螺纹轴颈（140） 所述第一对支柱将所述带螺纹的轴颈连接至所述第一板，并且所述第二对支柱将所述带螺纹的轴颈连接至所述第二板，使得旋转所述带螺纹的螺钉构件打开和闭合所述双折叠屏障构件。
