Abstract: 412,935. Converting. MARX, E., 3, Rankestrasse, Brunswick, Germany. Dec. 2, 1932, No. 34194. Convention date, Dec. 2, 1931. [Class 38 (ii).] In a converter of the kind in which an arc through a gaseous fluid is periodically initiated by an auxiliary arc, energy for which is stored in a capacity, the circuit arrangements are such that the voltage applied to the gap across which the auxiliary arc is formed is at least twice the absolute minimum required to break down the gap, and the value of the capacity is sufficiently large to give a stable arc. In one arrangement, Fig. 1, a D.C. circuit X is connected to an A.C. circuit through a transformer K and arc valves L, M, N. An auxiliary transformer A charges, through a rectifier B, a large condenser C which charges a condenser E through a resistance D. The condenser E is periodically discharged through the primary windings of high-frequency transformers G, H, J by the rotary spark gap F, and the voltages produced in the secondary windings of the transformers produce the auxiliary arcs in turn across the valves L, M, N. In a modification, Fig. 2 (not shown) the ignition circuit includes a number of condensers which are charged in parallel and discharged in series to produce the auxiliary arcs. Means may be provided for feeding pre-ionized gas to the path of the auxiliary arc before the arc is struck. Preionization can also be effected by inserting radium preparations in the electrodes of the valves. Specifications 400,934, 406,003, and 406,999, [all in Group XL], are referred to. Reference has been directed by the Comptroller to Specifications 21366/08, [Class 38], 5081 /09, [Class 40 (v)], and 254,746, [Class 38 (ii)].

Title: Process for the separation of hydrogen chloride from mixtures thereof with cyanogen chloride and chlorine
IPC: C01C3/00
Filed: 1969-07-09
Abstract: 1,268,673. Separating chlorine and cyanogen chloride from mixtures with hydrogen chloride. AGRIPAT S.A. 9 July, 1969 [10 July, 1968], No. 34482/69. Heading B1L. [Also in Divisions Cl and C2] Hydrogen chloride is separated from chlorine and cyanogen chloride by passing the mixture (which has originated from the catalytic production of cyanogen chloride from hydrocyanic acid and chlorine, or from the trimerization of cyanogen chloride to cyanuric chloride) by line 9 to jacketed absorber 1 where pentachloroethane is agitated in contact with the gas stream. The pentachloroethane preferably contains a small proportion of iodine to prevent undue chlorination by the chlorine in the gas stream. The bulk of the hydrogen chloride, which is not absorbed, rises through condenser 2 and leaves by line 10. Solvent containing cyanogen chloride and chlorine passes by line 3 to evaporator 4, and thence in gaseous form up through distillation column 5 to condenser 6. Solvent condensate therefrom is returned by line 13 to absorber 1, while cyanogen chloride and chlorine pass to reactor 7 which is irradiated with u.v. light. This causes any entrained solvent to be converted to hexachloroethane, which is condensed in liquid air trap 8. Residual gases pass by line 11 back to a cyanogen chloride or cyanuric chloride reactor.
