Patent GB-494738-A (GB)
Title: New heterocyclic compounds
IPC: C09B47/04
Filed: 1937-04-30
Abstract: Tetrabenztriazaporphins are manufactured by reacting an o-dinitrile of the benzene or naphthalene series with a methylenephthalimidine or a phthalimidylacetic acid or a metal salt thereof, e.g. the copper salt, or an o-acetylbenzamide, and a substance consisting of or containing a metal.  The products may be used as pigments.  They may be converted by the action of strong sulphonating agents into sulphonic acids, the alkali metal salts of which dye cotton, wool and acetate artificial silk green shades whilst the barium and other lakes thereof may be used, with or without admixture of white pigment, e.g. blanc fixe, in the surface colouring of paper.  The tetrabenztriazaporphins may also be halogenated, e.g. by dissolving or suspending them in a solvent or diluent, e.g. nitrobenzene or molten phthalic anhydride, at an elevated temperature and passing in chlorine gas or adding bromine or a solution thereof, e.g. in nitrobenzene, the reaction being advantageously effected in the presence of a halogen carrier, e.g. antimony trisulphide.  In some cases the halogenation is conducted in two stages, the first in the presence of a solvent or diluent and the second in a sealed pressure vessel.  In examples: (1) methylenephthalimidine (prepared by heating phthalimidylacetic acid with water) is heated with phthalodinitrile and cupric chloride; the product colours paints, lacquers and printing inks green shades; (2) a mixture of phthalimidylacetic acid, phthalodinitrile and magnesium turnings is heated in a -chloronaphthalene; by dissolving the product, which contains combined magnesium, in sulphuric acid and pouring the solution into hot water, there is obtained a metal-free compound, which may be incorporated in paints or lacquers; (3) phthalimidylacetic acid or 4-chlorophthalimidylacetic acid is heated with phthalodinitrile and cuprous chloride in a -chloronaphthalene; (4) phthalimidylacetic acid, phthalodinitrile and litharge are heated in a -chloronaphthalene; (5) stannous chloride is used in place of litharge in (4), yielding dichlorostannic tetrabenztriazaporphin; (6) phthalimidylacetic acid, 4-chlorophthalodinitrile and cuprous chloride are heated in a -chloronaphthalene; (7) 3 : 6-dichlorophthalonitrile or 4-amino- or 4-nitrophthalodinitrile is employed in the process of (6); (8) copper tetrabenztriazaporphin is heated with oleum and the resulting sulphonic acid is isolated in the form of its ammonium salt; the sulphonic acid dyes cotton, wool, acetate artificial silk and paper, and may be converted into a barium lake; (9) metal-free tetrabenztriazaporphin is treated with chlorine in molten phthalic anhydride, advantageously in the presence of antimony trisulphide; (10) copper tetrabenztriazaporphin is similarly treated; (11) metal-free tetrabenztriazaporphin is heated with bromine in nitrobenzene; (12) copper tetrabenztriazaporphin is treated as in (11); (13) the product of (12) is further heated with bromine in a pressure vessel.

Title: Improvements relating to arrangements in automatic telephone networks for the establishment of connections
IPC: H04Q3/00
Filed: 1946-04-25
Abstract: 625,025. Automatic exchange systems. RIGERT, E. April 25, 1946, No. 12569. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 26, 1946.] [Class 40 (iv)] In a system having exchanges A, B, C, D, when a subscriber of exchange D dials the prefix for exchange A which is only accessible through C, the first group selector IGWD is set onto a line L3 to C and an impulse sender ZGD is set according to the setting of the group selector and repeats the prefix over L3 to next exchange to set the incoming selector FGW2  onto a line L4 to exchange A. In any decade direct outlets are connected to the earlier contacts and indirect outlets to the later contacts. Thus, if selector FGW2 finds all direct outlets busy it proceeds to later contacts wired to outlets to exchange B, and impulse sender ZGC is set with the A exchange prefix and the call is thus passed through B to A. The impulse senders may be wired for translating the exchange prefix and may incorporate digit switches for registering the called subscriber's number for retransmission after the exchange-designating signals have been sent. The senders may be set by a hunting switch testing for potential placed on a decade test wire by the first group selector.
