Patent number: 4627907Abstract: An oxygen sensor having increased stability in its sensitivity is provided. The oxygen sensor includes a sensing electrode spaced from a cadmium counter electrode. An alkaline electrolyte extends between the electrodes and permits the formation of cadmium hydroxide in the counter electrode as the cell is used. An electrical circuit connects the counter electrode and sensing electrode externally of the cell. The circuit includes a resistor and thermistor network and a voltmeter. Readings on the voltmeter can be calibrated to show the concentration of ambient oxygen diffusing a polymer membrane to the sensor electrode.Type: GrantFiled: November 2, 1984Date of Patent: December 9, 1986Assignee: General Electric CompanyInventors: Leonard W. Niedrach, Fritz G. Will

Patent number: 4347429Abstract: An electrode boiler containing an aqueous electrolyte is provided with a pair of spaced electrodes immersed in the electrolyte and connected to an AC power source. Each electrode comprises an electrically conductive metal substrate having adhered to one face thereof a microporous electrochemically active mass comprising a reversible electrode couple covering essentially the entire face and being present in such quantity that at least some of each member of the electrode couple is present at all times during use. The electrodes are arranged with the active masses facing each other and in contact with the electrolyte. The electrode couple consists essentially of a material which is electrochemically reversibly oxidized and reduced in response to alternating current flow therethrough from one electrode to the other; thereby allowing high current density use without promoting corrosion or erosion of the electrodes.Type: GrantFiled: June 28, 1979Date of Patent: August 31, 1982Assignee: General Electric CompanyInventor: Fritz G.

Patent number: 4288683Abstract: An electrode boiler has a pair of boiler electrodes defining a volume therebetween to be filled with electrolyte to be heated by electrical current passage between the electrodes through the electrolyte. A porous insulating matrix is confined by a pair of porous insulating support walls between but spaced apart from said electrodes in the volume occupied by said electrolyte. The space between said walls is filled with a plurality of insulating members, thereby providing paths exhibiting increased resistance to electrical current flow relative to the electrical resistance of the electrolyte located between said electrodes and said support walls in the direction perpendicular to said support walls. The insulating members may comprise spheres, pellets or cylindrical rods or tubes made of glass, polymeric material, ceramics or the like.Type: GrantFiled: April 30, 1979Date of Patent: September 8, 1981Assignee: General Electric CompanyInventor: Fritz G. Will

Patent number: 4260874Abstract: A pair of boiler electrodes defines a volume therebetween to be filled with electrolyte to be heated by electrical current passage between the electrodes through the electrolyte. A microporous insulating barrier permeable to the electrolyte is disposed between the electrodes to limit current flow in the electrical current path between the electrodes to a level within the maximum allowable range of the electrode material, the barrier being spaced from the surface of the electrodes at least sufficiently to prevent concentration of current on the electrode surfaces. The barrier includes channels in the vertical direction to accommodate steam removal from the electrolyte.Type: GrantFiled: August 23, 1979Date of Patent: April 7, 1981Assignee: General Electric CompanyInventor: Fritz G.
