摘要: A marginal oil extraction system having an upper extraction unit, an extraction container, and a lower valve assembly. The marginal oil extraction system uses at least some of these components to cheaply extract oil from a stripper oil well. In some cases the system is capable of separating the oil from the water in the well with a solid barrier and can cheaply remove the oil from above the solid barrier. The system is cheap to install, easy to maintain and provides efficient access to what would otherwise be an inaccessible asset.

摘要: A method and apparatus for monitoring the flue gases of a furnace combustion process is disclosed. A by-pass circuit that communicates a sample of flue gases to be monitored from a furnace, through a measurement chamber and back to the furnace or furnace exhaust duct is provided. The by-pass circuit has a gas sampling probe with a fume inlet opening, the probe being positioned for withdrawing the sample to be monitored and transmitting it through the by-pass circuit. A measurement device is positioned in the measurement chamber and comprises an in situ optical device which provides real-time measurement of targeted flue gas species concentrations.

摘要: A method of providing secure multicast over a local access network by means of a network access unit having a channel request vetting function and a permitted channel list. Channel requests from a subscriber are vetted with respect to the permitted channel list and forwarded only if permitted. The permitted list may be dynamically updated under headend control to allow users to subscribe to, and unsubscribe from, services upon request.
