Abstract: 1467926 Carbon monoxide determination SIEMENS AG 22 Jan 1975 [23 Jan 1974 15 Nov 1974] 2869/75 Heading G1N Carbon monoxide is determined by the extent to which it inhibits an electro-chemical reaction. The reaction may be cathodic reduction of alcohol, or anodic oxidation of alcohol, preferably methanol, a glycol or glycerol. The inhibition may be determined from the change of current at constant voltage or the change of voltage at constant current. Preferably measurement of a reference gas and a CO containing gas are alternated, the reference preferably being prepared from the CO containing gas by removal of the CO; preferably by oxidation. The electrode at which the inhibition by CO is determined preferably comprises a catalyst which may be a noble metal e.g. Pt or Pd or CoP 3  or FeP 2 . The cell preferably has an acid electrolyte. As shown, the inhibition electrode comprises a body 101 provided with two bores 102, 103 for introducing and removing gas. A recess 104 forms the electrode compartment and into it are fitted a body 105 with longitudinal bores, a gold plated polypropylene cloth 108 functioning as a gas distributer, a fine carbon cloth 109 and a working catalyst layer 110 of platinum or palladium block. A gold wire 107 fed through inlet 102 and the bores 106 of body 105 makes electrical contact with the catalyst layer. A layer of asbestos paper 111, a polypropylene cloth 112 and a perforated tantalum plate 113 held in place by pressure ring 114 provide the means whereby electrolyte contacts the catalyst. Screw 117 seals bore 118. In use as shown, Fig. 5, the voltage between measuring electrode 120 and a Hg/HgSO 4 /K 2 SO 4  soln reference electrode 123 is maintained constant and the current between measuring and counter electrode 121 is measured as the voltage across resistor 129. The cell electrolyte is M H 2 SO 4  and the reference electrode is connected to the measuring electrode via porous diaphragm 122 and Luggin probe 124. Another cell construction is described and measuring and settling times between measurements for various CO concentrations are quoted.

Filed: 1920-01-30
Abstract: 156,420. Sauer, E. Jan. 30, 1920. Photo-mechanical printing-surfaces.-To make an intaglio printing-surface, a bichromated gelatine film on a thin transparent base is exposed from the front to a screen plate having transparent lines and opaque dots, and a diapositive oi the picture is printed through the transparent base from the back. After development, the screen lines printed on the gelatine film will be on the same level and the thickness of the lines will decrease in the depth of the film thereby forming intaglio hollows which are wider in the depth of the film than at the surface and forming a better holding for the ink. Also the lines or walls do not fall together when the plate is washed. To enable the gelatine film to withstand the action of the roller, it is moistened with acetic acid and coated with a film of zapon 'varnish.
