Title: Bromination process
Inventor: ADAM JOHN HUNTER
Filed: 1968-10-25
Abstract: 1291225 Preparation of 4-bromo-1-aminoanthraquinone-2-sulphonic acid IMPERIAL CHEMICAL INDUSTRIES Ltd 7 Jan 1970 [25 Oct 1968] 50789/68 Heading C4P 4 - Bromo - 1 - aminoanthraquinone - 2 - sulphonic acid is prepared by treating an aqueous solution of 1-amino-anthraquinone-2-sulphonic acid simultaneously with bromine and chlorine, thereby avoiding progressive increase in the aqueous concentration of bromide ion while bromination proceeds. The bromide ion concentration is 0À002 to 0À004 gram ions per litre. The bromine is preferably introduced into the aqueous solution in vapour form diluted with an inert gas, e.g. air, and optionally mixed with chlorine. In the example given the rate of introduction of chlorine is controlled according to a predetermined programme by a voltage signal from a silver/silver bromide electrode which is responsive to the bromide ion concentration. The end point of the reaction is determined by an electrode measuring the redox potential Br 2  + 2e#2Br.

Abstract: 1367825 Measuring colour photo-electrically GRETAG A G 3 Nov 1972 [3 Nov 1971] 50877/72 Heading G1A To measure the colour density of printing inks applied to a moving web of material to print multi-coloured matter thereon, a plurality of colorimetric scales 6, Fig.2 (not shown) are printed on the web in the direction of travel for monitoring by a photo-electric reading head, each scale comprising a plurality of different coloured zones M, N, C, Y, each of which comprises at least three different tones T, X, L of the zone colour, and a group of synchronizing marks S1, S2. A white reference level, which may be the background paper or a reference background 23, is provided. On each scale 6, each of the four complementary colours cyan (C), magenta (M), yellow (Y) and black (N) is divided into deep (T), medium (X) and light (L) tones. The colours are preferably applied to the zones M, N, C, Y in the same sequence as they are applied to the web in the colour printing process. As the scale 6 moves past a photo-electric reading head 24 the colour signals corresponding to the different tones are stored 18, 19, ... and are subtracted in turn at 21 from the reference white signal. The colour density values of the different tones are printed out at 22. A wheel 5 containing a plurality of different filters may be employed, rotated under control of the reference pulses, to furnish further spectral information. Automatic focusing is achieved by sensing the photo-cell output at 25 and moving the head 24 so as to maintain this output constant.

An actuating member 40 pivotally connected at 42 on the underside of body 10a has a latching shoulder 44 which engages a latching lip 38 on the signal member 24 to hold it in its storage position. On the opposite end 406 of the actuating member which directly communicates with guide groove segment 16a, there is a pair of walls 46a and 46b disposed in opposing angular directions to the longitudinal axis of the guide groove, so that regardless of which direction the vehicle 18 is travelling along guide groove 16a the depending guide 22 will strike either the wall 46a or 46b and as a result actuate the actuating member 40 through its unlatching stroke S about pivot 42. When this happens the unlatching shoulder 44 is moved free of engagement with the latching lip 38 so that the signal member 24, under the urgency of spring 36 is moved from its storage position into its raised position. Also the extension 48 of actuating member 40 held at its free end by stop 50 from moving is slightly bent and thus functions as a spring to produce an urgency biasing the member 40 to return back into its normal at-rest position. Channel 16b is continuous except at the point where it is intersected by actuating member section 40b. The discontinuation is preferably bridged by a connecting section 16c accommodating thereunder section 40b.

The tape 20 has a plurality of conductor elements 52 which are embedded in the insulating material of the tape. The tape 20 and a paper strip or sheet 51 are sandwiched between a backing member 41 and a printing head 42. The printing head has a plurality of electrodes 55 whose tips are distributed in the surface of the head in contact with the tape 20. A selection circuit 56 selects among the electrodes 55 a number of pairs whose tips define a set of lines each of which constitute one portion of the outline to be printed. One electrode of each pair is connected to the positive pole of an electric supply 58, the other to the negative pole, so that a current passes through the conductive ink between the tips of the selected pair of electroducers. In this way the ink is melted and transferred to the paper. Individual character printing with the head moving, line printing and whole page printing are possible depending upon the size of the printing head 42. In (Fig. 5), the endless tape 20 is passed continuously through a bath of molten ink (30). However, at the printing stage, the tape is advanced intermittently in synchronism with the paper tape 51, character by character. The difference between the continuous and intermittent movement of the tape 20 is accommodated with two tensioning rollers (25, 28) forming loops (61, 62).
