    Abstract: 1,125,241. Treating gases with electric discharges. WESTINGHOUSE ELECTRIC CORP. 12 Jan., 1967 [16 Feb., 1966], No. 1679/67. Heading H5H. [Also in Division C5] An arc heater for converting a process gas, such as methane, to a' product such as acetylene comprises annular electrodes 11, 12 adapted to be connected to a source of potential 153 to produce and sustain an arc 13 between electrodes 11, 12, means 14, 15 for generating a magnetic field which continuously moves the arc in a closed path, fluid cooled walls for the arc chamber including cylindrical fluid cooled heat shields 81, 82 having portions which shield the supporting portions of electrodes 11, 12, exhaust nozzle 86, and conduits: for introducing the process gas at at least one annular region where the gas flows across the arc path to reach the nozzle. Electrodes 11, 12 and nozzle 86 are fluid cooled. The chamber includes end plug 84, rings 51, 52 separating the electrodes and optional heat shield 80, all fluid cooled. End plug 84, heat shield 82, electrode 12, ring assembly 51, 52 electrode 11, heat shield 81, heat shield 80 and exhaust nozzle 86 are all electrically insulated from each other and a process gas, auxiliary gas or quenching gas can be introduced between them and also through passageways 136, 137 in shield 80 which may also be used for seeding or sampling. Tables and graphs show the results of three test runs where CH 4 is the process gas and three test runs where C 3 H 6 is the process gas, the composition of the product gas being analysed with respect to the three different flow rates and three different input powers and the product values obtained being shown with percent reference to the production of total carbon.
