摘要： A flow sub for use with a drill string includes: a tubular housing having a longitudinal bore formed therethrough and a flow port formed through a wall thereof; a bore valve operable between an open position and a closed position, wherein the bore valve allows free passage through the bore in the open position and isolates an upper portion of the bore from a lower portion of the bore in the closed position; and a sleeve disposed in the housing and movable between an open position where the flow port is exposed to the bore and a closed position where a wall of the sleeve is disposed between the flow port and the bore; and a bore valve actuator operably coupling the sleeve and the bore valve such that opening the sleeve closes the bore valve and closing the sleeve opens the bore valve.

摘要： There is disclosed a liquid confinement structure to control the depth of water contained by earthen levees in a rice field or the like and to allow excess water to flow through a gate therein to prevent overflow and washout of the levees. The structure includes a horizontally elongated panel of rigid sheet aluminum for placement in a gap in an earthen water containment levee. The panel has a central cutaway portion closed by a rigid gate about eight inches high by about four feet wide articulated by a flexible strip joining the bottom of the gate to the horizontal edge of the cutaway portion. When the gate is tilted downward to permit water flow to lower the level of the water, the water is prevented from flowing around the ends of the gate by flaps forming seals between the edges of the gate and the edges of the opening in the panel. The gate element is held at a desired angle for controlling water level by a restraining chain at each end of the gate, the links of which may be captured in a slot in the top of the panel adjacent the cutaway portion. Openings at the extremities of the panel provide hand holds or means for engagement of hooks to facilitate installing, handling, or removing the structures.

摘要翻译： 公开了一种液体限制结构，用于控制稻田等中的土堤所含的水的深度，并允许多余的水流过其中的浇口以防止堤坝的溢流和冲洗。 该结构包括一个水平伸长的刚性片状铝板，用于放置在一个土壤防水堤中的间隙中。 面板具有由刚性门约8英寸高至约4英尺宽的中心切口部分，该刚性门通过将栅极底部连接到切口部分的水平边缘的柔性带铰接。 当门向下倾斜以允许水流降低水位时，通过在门的边缘和面板中的开口的边缘之间形成密封的翼片防止水流过门的端部。 门元件被保持在期望的角度，以通过限制链在门的每个端部处控制水位，其链节可以被捕获在邻近切割部分的面板的顶部中的狭槽中。 面板四肢的开口提供手柄或钩子接合装置，以方便安装，搬运或拆卸结构。
