Title: New dyestuffs of the anthraquinone series
Inventor: HESLOP ROBERT NORMAN
IPC: C09B62/06
Filed: 1956-01-20
Abstract: The invention comprises dyes of the formula <FORM:0803473/IV (c)/1> wherein R1 is alkyl, hydroxyalkyl or aralkyl, R2 is alkyl, cycloalkyl, aralkyl or aryl, Y is hydrogen or sulpho and X is a bridging group (e.g. phenylene), which may be substituted, provided that the dyestuff molecule contains not more than two sulpho groups. They are made by roasting cyanuric chloride with, in either order, equimolecular proportions of an anthraquinone derivative of the formula <FORM:0803473/IV (c)/2> and a hydroxy compound of the formula R2OH.  The reaction is preferably carried out in presence of an acid-binding agent, and buffers giving a pH between 5 and 8 may be added during isolation of the dye or to the dyestuff pastes or powders.  The products dye wool reddish-blue to greenish-blue shades. In examples: (1) 2,4-dichloro-6-methoxy-s-triazine is reacted with (a) the disodium salt of 1-amino-4 - (41 - methylaminoanilino) anthraquinone-2,31 - disulphonic acid; (b) the sodium salt of 1 - amino - 4 - (41 - methylamino) anilinoanthraquinone - 2 - sulphonic acid; (c) the disodium salt of 1-amino-4-(31-b -hydroxyethylamino) - anilinoanthraquinone - 2 : 5 - disulphonic acid; (2) 2,4 - dichloro - 6 - phenoxy-s-triazine is reacted with the disodium salt of 1-amino - 4 - (41 - n - butylamino) anilinoanthraquinone-2,31-disulphonic acid. Compounds of formula R2-OH which are listed are methanol, ethanol, the propanols, the butanols, cyclohexanol, benzyl alcohol, phenol, and the cresols.  The bridging group X may be -C6H4-C6H4-or -C6H4-NH-C6H4- and may contain sulpho, alkyl, alkoxy or halogen atoms.  Specification 467,815, [Group IV], is referred to.

Abstract: 1,263,091. Easy-opening cans. CEBAL G.P. 20 Jan., 1969 [22 Jan., 1968], No. 3059/69. Heading B8D. A fully opening metal can end 4 comprises a removable panel 8 defined by a peripherallyextending continuous score line 7, and a pull tab 9 riveted at 28 to the panel and having a nose portion 26 for initiating rupture of the score line extending over and beyond the score line, said tab having a generally C-shaped cut 30, 31 defining a hinge line 33 between the nose portion and the rivet. On raising of the ring end 19 of the tab, the nose wipes along the end wall across the score line to indent the panel periphery at 35, Figs. 3 and 4 (not shown), and initiates rupture of the score line. The panel bends, on pulling of the tab, about an area 37 closer to the rivet thereby further retracting the nose as indicated at 40 inwards of the panel edge. The removable panel is provided with an inner shallower anti-fracture score line 46, a recess 41, and inwardly-formed arcuately-extending grooves 46, Fig. 3, the latter facilitating removal of the panel without lifting of the flange 44, strengthening of the cam end against flexing during cooking of the contents, and preventing dip-down of the end panel when finally removed. The tab has an apertured recess 13, communicating with a channel 17 extending towards the tab end and terminates in the rounded nose 26. TheC-shaped cut is formed in the base of the recess. The ring portion 19 of the tab and the outer side edges 24 are provided with rolled strengthening edges 21, 22, 25. Outwardly pressed louvres 18 are provided in the top wall of the tab and define edges 18a perpendicular to the tab plane of symmetry to facilitate correct location of the tab on the panel prior to riveting.

Abstract: 489,717. Television transmitters. BAIRD TELEVISION, Ltd., JONES, V. A., and NUTTALL, T. C. Feb. 2, 1937, No. 3063. [Class 40 (iii)] The signals from one scanner are periodically interrupted and replaced by those from another scanner, the signals containing their directcurrent components at the point of interruption, or being replaced during their period of interruption by a signal fixedly related to picture black. The scanners may be used for scanning the foreground and background separately as described in Specification 472,762, or the mixing may be performed when producing a " rolling cut " for changing from one scene to another as described in Specification 456,582. The two signals containing their direct current components may be applied to the control grids of valves 9, 10, Fig. 2, respectively, the valves being alternatively operative by applying inverse impulses to their screen grids ; a " rolling cut " is produced by widening the impulse. When the direct current components are not present, the two signals are applied to valves 12, 13, Fig. 3, rendered operative alternately as in Fig. 2 ; two further valves 14, 15 are biassed by the direct current components produced by the diodes 16, 17 and are rendered operative alternately so that one signal and the direct current component of the other signal is delivered to the output circuit. In a modification, the two picture signals, without direct-current components, are applied to valves 18, 19, Fig. 4, whose anodes are connected to the secondary emitting electrodes of two valves 20, 21 whose grids are energized by signals corresponding to the missing direct current components ; as a result, the current in the secondary electrode circuit may be made to be equal and opposite to that in the anode circuit of valve 18 when picture black occurs ; the valves 18, 20 are rendered conducting alternately with valves 19, 21 by pulses applied in opposite phase to the cathode resistances 22, 23. The pulses may be generated by scanning a black and white screen ; e.g. a white screen 25, Fig. 5, may be masked by an opaque sheet 29, the signals in the cell 27 being the desired pulses ; or an iris diaphragm may replace the sheet 29 ; or a smoked glass plate may be cleaned in suitable steps ; or a sheet of paper may be suitably torn away. When the background and foreground are scanned separately, the pulses may be produced by scanning the background on which the silhouette of the foreground appears, Fig. 6 (not shown). More than two scanners may be employed to produce insets. The invention may also be applied to wipe out the picture, the inserted signal then being blank. Specifications 470,785 and 472,401 also are referred to.
Patent GB-424919-A (GB)
Title: A process for coating surfaces of slate, concrete or brickwork
IPC: C04B41/50
Filed: 1934-01-30
Abstract: A process for coating the surface of slats, concrete or brickwork consists in applying a sol prepared from iron hydroxide or chromium hydroxide, or a mixture of these sols, drying the sol to form a film on the surface, applying thereto an electrolyte to convert the sol into a gel, and drying the gel.  A modification of the process consists in applying to the surface a coating of concentrated acid, a concentrated alkali solution or other electrolyte in solution, which solution reacts upon the surface to form a coagulant film, drying the coating, applying the sol to the treated surface, and drying.  In this case, gel formation commences on the underneath surface of the sol film, though a solution of an electroylte may be applied to the outer surface also of the sol film, to expedite the complete conversion of the sol into a gel.  Specified electrolytes are ammonium sulphate, potassium ferrocyanide and sodium silicate. Various colour effects may be obtained by adding to the sols, substances such as red oxide of iron, green oxide of chromium, black oxide of manganese, smalt or ochre.
