    Abstract: A modular vertical pump assembly has a motor, a coupling, a pump, a frame, and a base. The frame installs on the base around the pump, and supports of the frame hold a mount for the motor. The shaft from the motor extends through the mount, and the coupling installs between the motor shaft and a pump shaft. Preferably, the coupling uses an adapter and a stuffing box. Three supports fixedly attach to the mount and base, while one support is removable. To remove the pump for repair or replacement, the removable support detaches from the frame, and the pump detaches from the base and lifts from the frame's free side. Like the pump, the motor can be removed independently from the mount. In both cases, the coupling allows the pump's shaft to freely separate from the motor's shaft.

    Abstract translation: 模块化立式泵组件具有马达，联轴器，泵，框架和基座。 框架安装在泵周围的基座上，并且框架的支撑架保持电机的安装座。 来自电动机的轴延伸穿过安装座，并且联轴器安装在电动机轴和泵轴之间。 优选地，联接器使用适配器和填料函。 三个支架固定连接到安装座和底座上，而一个支架可移动。 为了拆卸泵进行维修或更换，可拆卸的支架与框架分离，泵从基座上脱离，并从框架的自由侧抬起。 像泵一样，马达可以独立于安装座拆下。 在这两种情况下，联轴器允许泵的轴与电机的轴自由分离。

    Abstract: Radiation shields include an outer composite wall, an inner composite wall, and an enclosed fuel chamber disposed between the inner and outer composite walls. A fuel may be contained within the enclosed fuel chamber. Spacecraft include one or more such radiation shields, and may further include a fuel cell and a conduit providing fluid communication between the fuel chamber of the radiation shield and the fuel cell. Methods of forming a radiation shield system include forming an enclosed fuel chamber between an outer composite wall and an inner composite wall of a radiation shield, and providing fuel within the enclosed fuel chamber.

    Abstract: Communication devices and communication network techniques are employed to meet safety-critical, operational requirements for train location and control in railroad and public transit applications. On-board and trackside communication radios participate in a synchronous, time-slotted communication network, providing contentionless and highly responsive access to all participants. Encrypted, validated, and error protected communication links provide reliable and redundant transfer of information among the train, trackside, and control station radios. Spread spectrum communication techniques enable range measurements between all participants. These wireless communication links relay train range measurements to control or processing stations and relay control information (principally speed commands) from the processing stations to the trains. High resolution position location is determined along elevated, at-grade, and in-tunnel tracks using wireless methods and sparse device placement.
