Abstract: An isolation circuit, which draws essentially zero current in a normal or stand-by state, uses a normally closed relay in combination with a storage element. A capacitor can be used as the storage element to energize the relay, using previously stored energy, in the event that a communication line to which the isolator is coupled exhibits a short circuit or low voltage condition. In this instance, the prestored energy on the capacitor activates the relay for a predetermined period of time, thereby open circuiting the communication line. When voltage is reapplied to one side of the isolator circuit, the relay is continuously energized and maintained in its open circuit condition until the low voltage or short circuit has been remedied.

Abstract: The invention provides a method for removing metal oxides and colloidal material from high-resistivity water streams at a relatively high removal efficiency. The method includes hydrating a highly ionized dual morphology ion exchange resin in a macroreticular, desiccated morphology to produce a macroreticular, hydrated morphology. A water stream which is brought into contact with the resin is purified. The water stream may, optionally, also be contacted with both a cation exchange resin and an anion exchange resin.The invention additionally provides a method for selecting ion exchange resins which are particularly suited for use in removing metal oxides from a condensate stream. The method serves to narrow the field of candidates for pilot-scale resin testing with industrial water streams.
