摘要： To heat the glow plug for an internal combustion engine, a spiral band or ribbon is wound in an essentially co-planar spiral about a central bolt secured to the bottom of the glow plug, the outer terminal of the spiral being connected to a lead-in with highly positive temperature coefficient of resistance to provide for self-limiting current flow upon heating of the glow plug. All free spaces in the glow plug are filled with a highly heat-conductive insulating material, for example magnesium oxide.

摘要： A housing of the device has a passage formed with two spaced open ends and with an inner circumferential shoulder. A tubular member of ion-conducting solid electrolyte material has a first closed-ended portion projecting from one of the open ends, and a second portion extending through the passage and being formed with an outer circumferential flange an axial end face of which faces the one open end and is supported by the shoulder. The interior of the tubular member is in communication with the ambient atmosphere, and an electron-conductive inner electrode is provided on an inner surface of the tubular member and conductively connected with an outside terminal portion. An electron-conductive outer electrode is provided on an outer surface of the tubular member and conductively connected with the housing. A compensating arrangement is provided on the housing fixed with reference thereto and engages the second portion of the tubular member in such a way as to compensate for differential coefficience of thermal expansion and contraction of the material of the housing and of the tubular member, respectively. This prevents relative movements of the housing and tubular member when such differential expansion or contraction occurs.

摘要： To provide for insulation between the conductors of a solid electrolyte ion-conductive oxygen measuring tube and a steel housing thereof, for introduction into the exhaust system of an automotive vehicle, the housing is formed with a shoulder against which a ceramic ring is seated, the tube passing through the ring, and likewise being formed with a shoulder seating against the ring. The outer conductor along the tube extends beyond the ring. A resilient electrically conductive mass such as graphite is packed around the tube, and spaced from the inner walls of the housing by a resilient mass of an insulating powder, such as talcum. The tube is held in position by a second insulating ring, the aperture of which is lined with a metallic sleeve contacting the electrically conductive powder and providing a contact connection to a terminal located in an end insulator secured to the housing; the interior of the tube is likewise connected to another terminal located in the insulator.

摘要： To improve operation and output voltage, particularly at 400.degree. C. and less, an oxygen sensor, especially adapted to determine oxygen content of automotive exhaust gases, is constructed by utilizing two electrodes applied on a body of stabilized zirconium dioxide, for example a closed tube, by making an electrode exposed to the exhaust gases in form of a mixture of finely dispersed ceramic material and a platinum-rhodium alloy, the ceramic material being present at about 40% (by volume) and 60% (by volume) platinum-rhodium alloy of 50-94% platinum and 50-6% rhodium (by weight). The second electrode, exposed to a reference gas comprises an alloy of palladium and another noble metal in a ratio of about 19-90% (by weight) Pd and 81-10% (by weight) noble metal. This electrode may also contain up to 40% (by volume) finely dispersed ceramic material. The electrode exposed to the exhaust gases is covered with a porous coating. The electrodes can be applied as aqueous or organic solutions of soluble noble metal compounds or suspensions, colloidal suspensions, with organic solvents, and the like, and subsequent sintering.
