An electrospray nozzle system is disclosed. The electrospray portion of the device comprises a substrate defining a channel between an entrance orifice on an injection surface and an exit orifice on an ejection surface, a nozzle defined by a portion recessed from the ejection surface surrounding the exit orifice, and an electrode for application of an electric potential to the substrate to optimize and generate an electrospray; and, optionally, additional electrode(s) to further modify the electrospray. The nozzle system may be utilized alone or as part of a liquid chromatography system.

A Utility Pole and Tower Safety and Protection Device includes a utility pole with a crossbar to support utility conductors. The crossbar is attached to the pole with a release mechanism. A pressure transducer is attached to the release mechanism and automatically controls the release and descent of the crossbar at a predetermined load limit. A shear pin may also be used if a mechanical system is desired. An alarm system is attached to the pole and linked to a relay station announces when the system is activated. Power and continuity to the utility conductors is terminated when the system is activated, virtually eliminating the risks of a downed utility conductor. The device protects power and utility lines from breakage due to external forces, such as weather or trees. When the external force is removed, the device is reset by winching the crossbar into position and resetting the release mechanism.
