Title: Improvements in or relating to the production of electrodes for electric cells and batteries
IPC: H01M4/72
Filed: 1964-07-13
Abstract: 1,039,194. Electric cells. YARDNEY INTERNATIONAL CORPORATION. July 13, 1964 [July 17, 1963], No. 28796/64. Heading H1B. A pasted electrode is made by mixing a powdered substance, which is thermally decomposable into active material, with a liquid to form a paste, disposing a planar support grid on a flat sheet of refractory non- absorbent material, depositing the paste within the interstices of the grid, exposing the flat sheet, and pasted grid to an elevated temperature sufficient to drive off most of the liquid, to decompose the powdered substance and to cause the powdered substance to adhere to the grid, and finally to remove the grid and paste which now form a plate from the sheet of refractory material. The refractory material is preferably aluminium since this normally has an oxide coating which will not adhere to the active material. As shown, a grid 16, e.g. of silver or copper, is fed from a supply roll 14 on to a refractory foil 13 which passes over a pasting table 12. Active paste, e.g. silver oxide + water, is fed on to the grid from a hopper 17 and is levelled into the grid by a doctor blade 18. The foil 13, grid 16 and paste then pass through a sintering furnace 22 where it is exposed to a temperature of 900‹ to 1200‹ F. for two minutes. The silver oxide decomposes into silver, the particles of which are sintered together and bonded to the grid. The grid carrying the active material is then removed from the foil 13 and is cut to size on a cutting table 26.

Patent GB-846869-A (GB)
Title: Preparation of tetrahalomethanes
IPC: A62D1/00
Filed: 1955-10-12
Abstract: The invention comprises a method for making tetrahalomethanes by reacting a carbonyl halide of general formula : <FORM:0846869/IV(b)/1> where X is fluorine, chlorine or bromine, and Y is chlorine or bromine with a fluorocarbonyl compound of general formula : <FORM:0846869/IV(b)/2> The fluorocarbonyl compound used as starting material may be formed in situ, by the reaction between COY2 and hydrogen fluoride, also when phosgene is used as a starting material, this may be formed in situ by reaction between carbon monoxide and chlorine.  The process of the invention may also therefore be carried out by reacting together carbon monoxide, chlorine and hydrogen fluoride.  The reactions may be carried out under batch or flow conditions at temperatures between about 250 DEG C. and 1400 DEG C.  Suitable pressures are those from atmospheric up to about 7500 p.s.i.g., preferably between about 700 and 4500 p.s.i.g.  In some cases it is preferable to add from about 0,1 to about 3 moles per mole of the phosgene or carbonyl bromide of chlorine or bromine to the reaction mixtures, or the disproportionation products CF3Y, CF4, CY3F, and CY4 may be added when CF2Y2 is the desired product.  When two different carbonyl halides are used as starting materials their molar ratio is preferably between 10:1 and 1:10, but when the carbonyl halides are the same, approximately stoichiometric proportions or excess of one carbonyl halide may be used, depending upon the reaction.  A catalyst, such as activated carbon which may or may not be impregnated with the halide of e.g. iron, vanadium, cobalt, nickel or aluminium, may be used, or mixtures thereof, e.g. ferric chloride on activated carbon.  Reactions specified are: COCl2+COF2=CF2Cl2+CO2 2 COFCl=CF2Cl2+CO2 COBr2+COF2=CF2Br2+CO2 2 COFBr=CF2Br2+CO2 COBr2+COFCl=CFClBr2+CO2 Other tetrahalorethanes specified are CF3Cl, CFCl3, CF3Br, CF4, CFBr3, CCl4 and CBr4. Examples are given.
