摘要:
A drill rig for drilling access holes in drill resistant materials, such as those used to construct safes or other secure containers. The drill rig includes a drill bit holding and advancing mechanism having enclosed threaded members for allowing incremental, even pressure to be applied during a drilling operation while preventing burrs and chips from becoming lodged within the threads. A sliding connection is provided between stationary frame structure of the rig and the drill bit holding and advancing mechanism. The connection includes a spring loaded, quick-release mechanism for allowing quick detachment of the drill bit holding and advancing mechanism from the frame structure at the end of a drilling operation or as needed to replace the drill bit.
摘要:
A hemispheric moving focus power plant (10) has a hemispheric solar reflector (12) for reflecting solar energy. A receiver (14) for receiving reflected solar energy and producing power therefrom is movably connected to the hemispheric solar reflector (12). The receiver (14) includes a frame with a top (24), to which a plurality of photovoltaic cells are connected, and a support (26). Further, a power conditioner (16) is connected to the receiver (14) for receiving power from the receiver (14) and conditioning the power for use.
摘要:
An inertial reference unit (IRU) is described which includes a processor programmed to provide inertial data from received inertial signals, a primary sensor unit providing the inertial signals to the processor, and an input/output (I/O) unit communicatively coupled to the processor. The I/O unit provides signals, including inertial data, to an external interface of the IRU and routes signals to and from the processor. The inertial reference unit also includes a secondary sensor unit separate from the primary sensor unit which provides inertial data independent of the inertial data provided by the processor.
