A system including a combined plug and valve device that may be precisely delivered to and inserted into an uncontrolled undersea oil well. Once positioned in the well, the device is operated in graduated fashion to anchor the plug to the well and gradually stanch the flow of oil from the well.

New solid state pH and sodium ion sensitive metal-oxide-type compositions, sensors and methods are disclosed. Performance thereof was demonstrated at ambient temperature with single crystals of several molybdenum bronzes (i.e. Na.sub.0.9 Mo.sub.6 O.sub.17, Li.sub.0.9 Mo.sub.6 O.sub.17, Li.sub.0.33 MoO.sub.3 and K.sub.0.3 MoO.sub.3) The pH sensors with Na-molybdenum-oxide bronzes show near ideal Nernstian behavior in the pH range 3-9. The response is not affected by the direction of the pH change.

Ion selective sensors based on molybdenum bronzes

A humidity sensing device comprising a solid electrolyte evidencing proton conductivity includes HZr.sub.2 P.sub.3 O.sub.12 or a composite comprising HZr.sub.2 P.sub.3 O.sub.12 /ZrP.sub.2 O.sub.7. The humidity sensing device is operative over a temperature range from 25.degree. C.-600.degree. C. The humidity sensor is operated by an impedance-type cell.
