摘要： A switching assembly for a hydraulic pump jack has a non-magnetic cylinder and a piston that is reciprocally movable within the interior bore of the cylinder. The piston has circumferential sealing means to engage the interior surface of the cylinder, and carries a magnetic element. A fluid source supplies a working fluid to the cylinder to move the piston within the cylinder. At least one magnetic sensor having a unique sensor value is externally mounted adjacent to the non-magnetic cylinder and senses at least a top of a piston stroke and the bottom of the piston stroke. A controller receives signals from the magnetically-actuated sensors as the magnetic element carried by the piston comes in proximity with and influences the at least one magnetic sensor. The controller controls piston positioning by selectively controlling the flow of working fluid to the cylinder.

摘要： In a method for manufacturing a plastic-lined metal tank, a permanent fitting having a flow passage is secured within an opening in the tank wall. A lower portion of the fitting has fitting anchorage means and protrudes into the tank interior. A temporary plug is disposed within the fitting's flow passage. A plastic material is introduced into the tank, which is then multi-axially rotated by a rotational molding apparatus while introducing heat to melt the plastic material. The molten plastic is deposited to form a liner over the inner surface of the tank shell and over exposed surfaces of the fitting and temporary plug. After the plastic liner has cooled and solidified, the temporary plug is removed from the fitting, and the liner is trimmed as required to allow fluid flow through the fitting's flow passage.

摘要： A magnetic safety valve for installation through a tank wall incorporates a piston movable within a valve body. The valve is held normally-closed by two opposite-pole magnets, one in the inner end of the piston, and one in the valve body. A vacuum produced by a pump connected to the valve will act upon the outer end of the piston, producing a force tending to move the piston outward. When the vacuum-induced outward force on the piston exceeds the attractive force between the two magnets, it pulls the piston outward and away from the valve body magnet, unseating the inner end of the piston from the valve body, and allowing outward fluid flow through the valve. A second valve seat may be provided for engagement with an outer portion of the piston to prevent uncontrolled fluid flow out of the tank in the event of valve damage.
摘要翻译：用于通过罐壁安装的磁性安全阀包括可在阀体内移动的活塞。阀门由两个相反极的磁体保持常闭，一个位于活塞的内端，一个位于阀体中。连接到阀的泵所产生的真空将作用于活塞的外端，产生趋向活塞向外移动的力。当活塞上的真空引起的向外力超过两个磁体之间的吸引力时，其将活塞向外拉动并远离阀体磁体，将活塞的内端从阀体上移开，并允许向外的流体流过阀门。可以设置第二阀座以与活塞的外部部分接合，以防止在阀损坏的情况下不受控制的流体流出罐。
