Abstract: 386,678. Systems depending on static transformers. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) July 20, 1931, No. 20742. Convention date, July 21, 1930. [Class 38 (iv).] In a system in which an alternating potential is impressed upon the direct current potential applied to an,arc lamp, cathode glow lamp or the like to cause light fluctuations corresponding to the form of the impressed potential wave, and in which magnetization of a transformer by the flow of direct current in its primary winding is suppressed, magnetization by the direct current potential applied to the lamp is prevented by including in the circuit of the secondary winding a compensating voltage. As shown in Fig. 1, a source 14 is opposed to the source 22 supplying the lamp 1. In the modification shown in Fig. 2, the secondary winding 26 is connected across equipotential points of a resistance bridge one limb of which contains the lamp 1. One or more of the resistances may be continuously variable to provide for accurate suppression of the preliminary magnetization of the transformer. Specification 287,560, [Class 39 (i), Electric lamps, Arc &c.], is referred to. The Specification as open to inspection under Sect. 91, describes also a condenser and oscillation damping resistance connected between the lamp and transformer secondary and an arrangement in which the magnetization of the transformer by direct currents in the primary and secondary windings are balanced by correctly relating the numbers of turns and the sense of the respective transformer windings.

Abstract: Styrene and benzene are prepared by compressing and heating a mixture of acetylene and monovinyl acetylene in a solvent using triphenyl phosphine nickel-bicarbonyl as a catalyst. Alternatively acetylene alone may be compressed and heated in a solvent with a co-catalyst, which dimerises it to monovinyl acetylene, in addition to the above catalyst.  Suitable co-catalysts are the complex compounds of copper or mercury halides with trialkyl- or triaryl-phosphine, or the complex compounds of copper halides with ammonium halides or with amine hydrogen halides.  The amount of the main catalyst is preferably about 3-10 per cent by weight of the solvent and the amount of the co-catalyst is 0.15 to 1.0 per cent.  The components of each complex compound may be added.  Benzene, acetonitrile or tetrahydrofuran are preferred as solvents.  Preferably a mixture of a solvent, nitrogen, acetylene and monovinyl acetylene are treated in a pressure-tight vessel in the presence of the catalyst at a pressure in the range 70 to 700 lbs./sq. inch and a temperature in the range 40 DEG  to 150 DEG  C.  A small amount of polymerization inhibitor, such as hydroquinone or pyrogallol may be added to the mixture.
