摘要： A drill bit for drilling a wellbore, the drill bit having a body and at least one bearing. A rotary cone is rotatably attached to the bit body at the bearing. A lubricant reservoir is located in an inner portion of the bit body and is in fluid communication with the bearing. A communication port leads from the inner portion of the bit body to the exterior of the bit body. A fiber reinforced elastomeric pressure compensator diaphragm separates lubricant in the lubricant reservoir from the communication port.

摘要： An assembly controls the liquid level in a vessel in which a submersible pump is disposed. The assembly has a switch housing and a float housing, arranged proximate to each other. A switch in the switch housing selectively energizes a motor associated with the pump. When a float disposed in the float housing moves in response to a change in the liquid level of the vessel, the movement is coupled to the switch by a pair of magnets arranged in attractive relationship to each other. One of the magnets is in the switch housing and the other is in the float housing. The magnets interact by providing force fields that acts through a wall that separates the switch housing and the float housing. A lever on which the switch housing magnet is positioned tilts the magnets away from alignment as they approach each other, reducing the increase in attractive force therebetween.
摘要翻译：组件控制在其中设置潜水泵的容器中的液面。组件具有彼此靠近设置的开关壳体和浮动壳体。开关壳体中的开关选择性地激励与泵相关联的电动机。当设置在浮动壳体中的浮子响应于容器的液面的变化而移动时，通过以彼此有吸引力的关系布置的一对磁体将运动耦合到开关。磁体中的一个位于开关壳体中，另一个位于浮动壳体中。磁体通过提供通过分隔开关壳体和浮动壳体的壁而作用的力场相互作用。开关壳体磁体定位在其上的杠杆使它们彼此接近时使其远离对准倾斜，从而减小了它们之间的吸引力的增加。

摘要： An earth boring bit has rotating cones with two lubricant passages to increase bearing capacity and cause lubricant circulation. A lubricant reservoir in the body supplies lubricant to passages between the cone and bearing pin. A pressure compensator equalizes lubricant pressure to the exterior of the bit. A first passage leads from the reservoir to the upper side of the bearing pin. A second passage leads from the reservoir to the bearing pin at a point from 185 degrees to 225 degrees as seen from an inner end of the bearing pin. This point is located in a diverging region 51d of an annular clearance surrounding the bearing pin.
