Title: Improvements in the formation of anodes in current-converting tubes
IPC: H01J9/385
Filed: 1945-10-09
Abstract: 601,870. Discharge converters. PHILIPS LAMPS, Ltd. Oct. 9, 1945, No. 26310. Convention date, July 27, 1940. Drawings to Specification. [Class 39 (i)] The anodes of converters are treated to minimise back-ignition by subjecting them to a glow discharge in a gaseous medium under constant conditions of pressure and current density, until the occurrence of back ignition as indicated by a device responsive thereto has ceased for a time sufficient to ensure that further back ignitions are not to be expected under the conditions of the treatment. The current density and voltage conditions during the forming operation are in excess of those occurring in the normal working for which the converter is rated. The gas filling may be any of the rare gases, nitrogen, hydrogen, oxygen, or mercury vapour or mixtures thereof and the pressure not less than 3 mm. of mercury. The anodes treated may be of graphite, or non-homogeneous composition such as mixtures of carbon graphite or carbides which have been sintered or baked together with binding agents such as clay or bituminous substances ; the treatment may also be applied to aluminium or carbonized nickel anodes. Alternating or direct current may be used, and the treatment may be applied in the envelope of the rectifier, or in a separate envelope. The gas pressure may be reduced by utilising a magnetic field to lengthen the path of the electrons and so increase the degree of ionisation and the intensity of the glow discharge current, as described in Specification 488,886. The glow discharge may be used simultaneously with an arc discharge. The subject-matter is identical with that of Specification 559,515.

Patent GB-661533-A (GB)
Title: Stabilized diazonium salts and process of effecting same
Filed: 1949-10-13
Abstract: Stable diazonium salts are manufactured by adding to a diazotization solution a substantial amount (e.g. 5-20 per cent of the amount of diazonium compound) of an anionic surface-active agent containing an aliphatic hydrophobic group and an aliphatically linked hydrophilic group, and (preferably subsequently) another compound capable of forming a stable salt with the diazonium compound (e.g. mercury, iron, zinc, cadmium, tin, antimony, platinum, gold, copper or arsenic chloride, naphthalene-1 : 5-disulphonic acid or fluoboric acid). Suitable surface active agents are alkali metal soaps (e.g. sodium oleate or stearate), sulphates of higher fatty acids (e.g. sulphonated castor oil), sulphonated or sulphated higher fatty alcohols (e.g. cetylsulphonic acid, sodium dodecylsulphonate or sodium lauryl sulphate), phosphated higher alcohols (e.g. (C8H17)6Na6P8O20), petroleum sulphonates, sulphosuccinic acid esters (e.g. the dibutyl or diamyl ester of sodium sulphosuccinate), acylamidoalkyl sulphonates and carboxylates (e.g. C17H33CON(CH3)C2H4SO3Na or the sodium salt of oleylsarcosine), alkylsulphonamido alkylsulphonates or acetates (e.g. CH3(CH2)13-15SO2NHCH2SO3Na or CH3 (CH2)13-15SO2NHCH2COONa), mixed fatty acid monoglyceride sulphates, alkylphenoxyalkyl sulphates (e.g. the sodium sulphuric ester of isooctyl-, dodecyl- or tetramethylbutyl-phenyl monoglycol ether), and amine soaps of fatty acids (e.g. the stearate of 2-amino-1-butanol).  The stable diazonium salt may be separated by filtration and mixed with a dehydrating agent (e.g. anhydrous sodium or magnesium sulphate or partially dehydrated aluminium sulphate).  Examples describe the use of certain of the foregoing stabilizers and the diazotization or tetrazotization products of the following amines: 4- and 5-nitro-o-anisidine, 2 : 5-dichloraniline, 4-chloro-o-toluidine, 4- and 5-chloro-o-anisidine, 2-nitro-p-anisidine, dianisidine and 41-amino-61-methyl-m-benzanisidide.  The Specification as open to inspection under Sect. 91 comprises also an example in which diazotized 41-methoxy-4-aminodiphenylamine is stabilized by means of the diamyl ester of sodium sulphosuccinate alone.  This subject-matter does not appear in the Specification as accepted.
