摘要： An overfill prevention device for storage tanks includes an elongate tubular housing having a liquid flow passageway. A normally open main valve and a normally closed vapor retaining bleed valve are associated with the fluid passageway. Closure of the main valve interrupts the primary flow of liquid through the passageway and closure of the bleed valve prevents any further liquid from entering the tank and also prevents the escape of vapors from the tank. Operation of the main valve is controlled in significant part by a valve latch assembly which is carried by the housing and a relatch assembly which is carried by the main valve. The relatch assembly ensures operative engagement of the main valve with the valve latch assembly upon movement of the main valve from the intermediate position to the open position. Operation of the main valve and vapor retaining bleed valve is also controlled indirectly by a plurality of floats which are maintained in a float chamber extending adjacent the liquid passageway. Deflecting fins are also provided in the fluid passageway for preventing damage to the main valve when an elongate measuring member such as a gauge pole is inserted into the tank for measuring the level of liquid therein.
摘要翻译：用于储罐的溢出物防止装置包括具有液体流动通道的细长管状壳体。常开主阀和常闭蒸气保持放气阀与流体通道相关联。主阀的关闭中断了通过通道的液体的主要流动，并且泄放阀的关闭阻止任何进一步的液体进入油箱，并且还防止蒸汽从罐中逸出。主阀的操作通过由壳体承载的阀闩组件和由主阀承载的重合组件来主要控制。当主阀从中间位置移动到打开位置时，重合组件确保主阀与阀门闩组件的有效接合。主阀和蒸汽保持放气阀的操作也由多个浮子间接地控制，浮子保持在邻近液体通道延伸的浮子室中。流体通道中还设有偏转翅片，用于防止当诸如计量杆的细长测量构件插入罐中以测量其中的液体水平时对主阀的损坏。

摘要： A foldable wheelchair includes a pair of side frames each of which have generally horizontal upper and lower members which are connected by generally vertical front and back legs. A pair of cross arms are located between the side frames and each arm has a base portion connected to a lower side frame member. A top portion of each cross arm is connected to an upper side frame member through a positioning link. The side frames are laterally and vertically positioned with respect to each other by a pair of positioning braces each located on a base portion of a different cross brace. Each brace contacts the top portion of the remaining cross brace and thus positions the side frame. The wheelchair has a removable rigid seat to permit access to the cross braces so the wheelchair can be folded.

摘要： A fuel dispensing nozzle easily and readily convertible between two modes which meet the regulations and operational requirements of the United States and European countries, the nozzle including a body member having a fuel passageway therethrough, a main valve in the fuel passageway to control the flow of fuel through the passageway, the main valve being removably mounted in the fuel passageway and reversible when the nozzle is to be converted into a different mode, and a valve actuating mechanism for opening the main valve in one direction when the main valve is in one attitude and in the opposite direction when the valve is in its reversed attitude.
