Title: Shaped energy transmission arrays and a process for manufacturing same
IPC: H01P3/20
Filed: 1968-06-13
Abstract: 1,218,107. Conduits. DECITRON ELECTRONICS CORP. 13 June, 1968 [29 Feb., 1968], No. 28179/68. Heading H2C. [Also in Division G2] A shaped energy transmission array having a plurality of channels (12), Fig. 1 (not shown) is made from a sheet comprised of these channels; the sheet is bent along a line 18, Fig. 2 (not shown), to form overlapping portions (19) and the portion extending normally from the edge 16 is shaped so that the edge defines the desired shape and lies in a single plane. The array is used as a light or electrical conductor. Edges 14 and 16 defining input and output edges or vice versa and the output edge may be shaped to any desired configuration such as letters of the alphabet or numbers 0-9, whilst the input edge 14 is a straight line. In another embodiment, Fig. 12 (not shown), the shaped array (30) is formed from a sheet which is bent twice along lines (34) and (36) and the portion extending normally from edge (40) is bent to any desired shape in the manner described above. The angle between line 18 and the edge 16 is 45 degrees and hence the edges 14 and 16 are in planes which are normal to each other and the edges (38) and (40), Fig. 12 (not shown), lie in parallel planes; by varying the angle the edges can be disposed in a wide range of planes. The bend 18 is gradual and arcuate in order to prevent sharp discontinuities that would effect the energy transmission characteristics of the array, and also permits the spacing of overlapping sections (19) to avoid cross-talk when the sheet is formed from electrical conductors, and means may be provided to maintain this spaced relation. The sheet 10 may be formed from a sheet of flexible circuitry, or from a plurality of filaments such as electrical conductors and fibre optical filaments. A process for manufacturing such a sheet is to helically wind a single length of filament on a mandrel (42), Fig. 7 (not shown) which may be cylindrical, and the windings are secured by an adhesive tape (46), Fig. 7, of synthetic resin. Alternatively flexible resins or silicone rubber may be used for securing the windings. The filaments are then cut along line (48) to form the required sheet 10. Various types of fibre opticalfilaments are described, Figs. 8-10 (not shown). Fig. 11 (not shown) has an array formed from electrical conductors comprised of insulated two-wire cables (66) which are secured together by tape (74). The array may be shaped by hand or through the use of mating dies of the desired shape, and then fixed by a potting material such as an epoxy or may be bracketed. Some materials may require heating to achieve sufficient flexibility before shaping.

Title: New azo dyestuffs
IPC: C09B47/08
Filed: 1945-10-30
Abstract: Green water-insoluble phthalocyanine-azo colouring matters are manufactured in substance or on the fibre by coupling the diazonium derivative of an aminophthalocyanine, carrying at least two amino groups in aryl nuclei attached either directly or through linking atoms or groups of atoms to the phthalocyanine nucleus, with an azoic coupling component which gives a yellow or orange water-insoluble dyestuff when coupled with diazotized p-nitraniline.  Advantageously there is added to the diazonium solution, especially if it has to stand for some time before use, a non-iogenic dispersing agent to obviate the tendency to form a precipitate.  In examples: (1) copper tetra - 4 - (p - aminobenzoyl) - phthalocyanine is tetrazotized and coupled with 1-phenyl-3-methyl-5-pyrazolone; (2) the coupling component in (1) is replaced by bis-acetoacet-o-tolidide; (3) cotton yarn is impregnated with an alkaline solution of bis-acetoacet-o-tolidide and developed with a solution prepared by diazotizing copper tetra-4-(p-aminobenzoyl)-phthalocyanine in the presence of the condensation product of cetyl alcohol with 17 molecular proportions of ethylene oxide, adding sodium acetate solution and diluting with water containing maleic acid; (4) the diazo component in (3) is replaced by copper tetra-4-(p-aminophenylmercapto)-phthalocyanine and the dispersing agent by the condensation product of b -naphthol with 10 molecular proportions of ethylene oxide; (5) and (6) cotton fabric is padded with an alkaline solution of bis-acetoacet-o-tolidide and printed with pastes prepared in the same way as the diazo solutions of (3) and (4) respectively except that the final dilution is effected with starch-tragacanth thickener.  A table shows the properties of further dyestuffs, the following additional components being specified: diazo components: nickel tetra-4-(p-aminobenzoyl)-phthalocyanine, copper tetra - 4 - (m - aminobenzoyl) - phthalocyanine, copper tetra-4-(p- and m-aminophenylsulphonyl) - phthalocyanine, copper 3 : 6 - dichloro - 41 : 411 : 4111 - tri - (p - aminophenylmercapto) - phthalocyanine, copper 3 : 6 : 31 : 61-tetrachloro - 411 : 4111 - di - (p - aminophenylmercapto) - phthalocyanine, copper tetra - 4 - (o - aminophenylmercapto) - phthalocyanine and copper tetra - 4 - (41 - amino - 31 - methylphenylmercapto) - phthalocyanine; coupling components: terephthaloyldiacetic - bis - 5 - chloro-2 : 4-dimethoxyanilide and -4-chloro-2-methoxy - 5 - methylanilide, 2 - acetoacetylamino - 6 - ethoxybenzthiazole, diphenyl - 4 : 41 - bis - (311-methyl-511-pyrazolone) and its 2 : 21-and 3 : 31 dimethyl derivatives, acetoacetyldehydriothio-p-toluidine and 4 : 41-bis-(acetoacetylamino)-azobenzene.
