摘要： In combination with a pump, a valve for operation at the interface between underlying heavier liquid and overlying lighter liquid is disclosed. The valve includes an inlet within the heavier liquid communicated from a valve seat to a conduit which typically is connected to the inlet of a pump. A valve disc opens and closes the valve seat to admit the heavier liquid to flow to the pump. The pump is preferably pneumatic and of the type which when flooded with liquid, automatically undertakes pumping and when empty of liquid ceases pumping. A buoyant member having a specific density between that of the lighter liquid and the heavier liquid is buoyantly supported at the interface and moves with the interface. This buoyant member is connected to an assembly which actuates the valve. Where lighter liquid is predominantly present, the float sinks and closes the valve preventing pumping. Where heavier liquid is predominantly present, the float rises, opens the pump inlet to permit pumping. Specific mechanisms are present for valve operation including a surrounding casing for protecting the valve from debris and a rocker arm arrangement for valve operation.
摘要翻译：结合泵，公开了一种用于在下层较重液体和上层较浅液体之间的界面处操作的阀。该阀包括在较重液体中的入口，该入口从阀座连接到通常连接到泵的入口的导管。阀盘打开和关闭阀座，以允许较重的液体流入泵。泵优选是气动的，并且是当液体充满液体时自动进行泵送，并且当空的液体停止泵送时。在较浅的液体和较重的液体之间具有特定密度的浮力部件在界面处被浮力地支撑并与界面一起移动。该浮力构件连接到致动阀的组件。当主要存在较浅的液体时，浮子沉没并关闭阀门以防止泵送。当主要存在较重的液体时，浮子上升，打开泵入口以允许泵送。存在用于阀操作的具体机构，包括用于保护阀免于碎屑的周围壳体和用于阀操作的摇臂装置。

摘要： The integrated universal tool is a novel combination tool which provides these functions: A locking knife blade, a locking saw blade, a locking Phillips bladed screwdriver, a locking small flat bladed screw driver, a locking large flat bladed screwdriver, a crescent wrench, graduated calipers for measuring inside and outside dimensions, left and right-handed shears, a nibbler, a wire stripper, and an electrical terminal crimping tool. This combination of tools is allowed by the use of the integrated universal. The universal is a universal joint located at the end opposite the crescent wrench. The blades of the tool are fastened to this universal joint and can be rotated into the extended or retracted positions about its two axes. This allows three extended blade positions and one closed position. The integration is the integrating slide.
摘要翻译：集成通用工具是提供这些功能的新型组合工具：锁定刀片，锁定锯片，锁定十字刀片螺丝刀，锁定小型扁平螺丝刀，锁定大型平头螺丝刀，新月形扳手，渐变用于测量内部和外部尺寸的卡尺，左右剪刀，冲头，剥线器和电气端子压接工具。这种组合工具可以通过使用集成通用的方式来实现。通用型是位于新月形扳手相对端的通用接头。工具的刀片固定在这个万向接头上，可以绕其两个轴线旋转到延伸或缩回的位置。这允许三个扩展刀片位置和一个关闭位置。整合是整合幻灯片。
