摘要:
Cathodic protection (CP) monitoring methods, systems and system components that provide regular (typically daily or more frequent) potential data collection for accurate assessment of CP systems. The methods, systems and components of the invention are used for remote monitoring of passive sacrificial anode CP systems and more particularly for monitoring of CP protection for buried storage tanks. These systems have on-site components for collection of data and transmission of data to remote databases and can employ computer-implemented and/or system operator assessed data processing and interpretation of data to assess protection status of a given structure and further to generate appropriate reports of protection status and collected and processed data.
摘要:
A process for the oligomerization of ethylene to a mixture of olefinic products having high linearity is provided, by using a catalyst comprising a reaction product of a simple divalent nickel salt; a boron hydride reducing agent; a water soluble base; a ligand selected from the group consisting of an o-dihydrocarbylphosphinobenzoic acid and alkali metal salts thereof; and a phosphite.
摘要:
A headlamp illumination source that switches from a first configuration conforming to on-road illumination standards to a second configuration that does not conform to on-road illumination standards. The switching is preferably controlled by a wireless signal but in some embodiments the switching can be controlled by a hard-wired signal or by a switch proximate the illumination source itself.
