Abstract: The invention is directed to a composite article suitable for use in thermoelectric generators. The article comprises a thin film of titanium nitride as an electrode deposited onto solid electrolyte. The invention is also directed to the method of making same.

Abstract: A composite article comprising a porous cermet electrode on a dense solid electrolyte and method of making same. The cerment electrode comprises beta-type-alumina and refractory metal.

Abstract: A partial pressure of oxygen sensor which finds utility when inserted into an exhaust system of a hydrocarbon fuel burning device. The oxygen sensor includes a mounting body both (a) threaded on one end for securement to the exhaust system, and (b) having a cylindrical configured bore extending along a central axis thereof. A heated sensing element is also provided which includes a ceramic support, a resistance heater element, and a titania dioxide sensor element in juxtaposition to the resistance heater element. An insulator body having a cylindrical configuration receives the heated sensing element therewithin. The insulator body is mounted in the cylindrical configured bore of the mounting body in a manner that the heated sensing element projects beyond a threaded end of the mounting body.

The oxygen sensor includes a mounting body both (a) threaded on one end for securement to the exhaust system, and (b) having a cylindrical configured bore extending along a central axis thereof. A heated sensing element of cylindrical configuration is also provided which includes a ceramic support, a resistance heater element wrapped around the ceramic support, and a titania dioxide sensor element closely located to the resistance heater element. The heated sensing element is mounted in the cylindrical configured bore of the mounting body in a manner that the titania dioxide sensor thereof projects beyond a threaded end of the mounting body. A protection device is provided over the titania dioxide sensor to protect the same and to permit exhaust gases to flow thereby.

Abstract: A partial pressure of oxygen sensor which finds utility when inserted into an exhaust system of a hydrocarbon fuel burning device. The oxygen sensor includes a mounting body threaded on one end for securement to the exhaust system and having a conical configured bore extending along a central axis thereof and having its smaller end at the threaded end of the mounting body. An elongated heated sensing element is also provided which includes a ceramic support, a resistance heater element, and a titania dioxide sensor element bonded to a leading portion of the ceramic support. A plurality of electrically conductive paths are provided on the ceramic support for the elements contained thereon. An insulator body having a conical configuration sandwiches the heated sensing element therewithin. The insulator body is mounted in the conical configured bore of the mounting body in a manner that the heated sensing element projects a fixed distance beyond the threaded end of the mounting body.
