Title: Solid electrolyte exhaust gas oxygen sensor
IPC: G01L/
Filed: 1978-07-10
Abstract: An exhaust gas oxygen sensor comprises a zirconia disc 1 having a catalytic electrode 5 on one face thereof and a non-catalytic electrode 7 on the other face and is adapted for mounting in an internal combustion engine exhaust duct 17 with both electrodes exposed to the exhaust gases. With this arrangement, the relatively small change in the partial pressure of the oxygen at the non-catalytic electrode 7 between a rich and lean mixture as compared with the relatively large change produced at the catalytic electrode 5 by the catalytic action provides a suitable reference for operation of the cell. The disc 1 is mounted on edge in a ceramic base 3 with the plane of the disc parallel to the exhaust gas flow to minimize abrasion by particle bombardment. Electrical leads 13, 15 connected to annular conductors 9, 11 in electrical contact with the electrodes 5, 7 on the respective faces of the zirconia disc 1 extend through the ceramic base 3 to form a two prong connector. <IMAGE>

Filed: 1979-05-24
Abstract: A relief image, e.g. for use as a printing plate, is formed by imagewise exposing a light-sensitive sheet material having a light-sensitive resin layer on a support, and the exposed layer is intimately contacted (e.g., by passage between pressure-applying rollers) with a carrier sheet (e.g., of paper or a polymer film) with a liquid promoter present (which may be coated on the light-sensitive layer or on the carrier sheet, prior to the contacting) which acts to selectively swell, plasticise or dissolve the exposed or unexposed areas of the layer or to reduce adhesion between the layer and its support; the carrier sheet is then separated from the sheet material, with portions of the light- sensitive layer, so as to leave a relief image on the support. The transferred portions on the carrier sheet can be used to check the quality of the image. Suitable types of the liquid promoter are organic solvents able to permeate the light-sensitive layer, surfactants, alkalis, acids and water.
