Title: Process for colouring organic products with pigment dyestuffs
IPC: C08K5/00
Filed: 1958-10-02
Abstract: Organic products such as plastics, synthetic resin lacquers, nitro-cellulose lacquers and spinning solutions for the production of spun-dyed artificial filaments are coloured with anthraquinone dyestuffs of the general formula <FORM:0880575/IV (a)/1> in which X represents a sulphur atom or an - NH-group.  In an example, 5 parts of diisothiazole-anthrone is ground with 95 parts of dioctyl phthalate, 0,8 part of the resulting paste is mixed with 13 parts of polyvinyl chloride, 7 parts of dioctyl phthalate, 0,1 part of cadmium stearate and 1 part of titanium dioxide, and the mixture is rolled on a two-roller mill at 140 DEG  C. to form a yellow sheet.  In a second example, 40 parts of a nitrocellulose lacquer, 2,4 parts of titanium dioxide and 0,125 part of dipyrazoleanthrone are ground for 16 hours in a rod mill to form a yellow lacquer.  In a third example, 0,25 part of the dyestuff used in the first example is ground for 24 hours in a rod mill with 40 parts of an alkyd-melamine bakeable lacquer containing 50% solids, and 4,75 parts titanium dioxide. In a fourth example, 4,8 parts of the dyestuff used in the second example are ground with 4,8 parts of dinaphthylmethane disulphonic acid and 22,1 parts water and the mixture is added to a viscose spinning solution. German Specifications 255,641 and 343,065 are referred to.ALSO:In an example of a process for colouring organic products with pigment dyestuffs of the formula <FORM:0880575/IV (c)/1> where X is sulphur or a group-NH-, a cotton fabric is entered in the dry state at room temperature into a dyebath containing, in 1,000 parts of water, 15 parts of a copolymer of 85.8 parts of isobutyl-acrylate, 9.6 parts of acrylonitrile and 4.6 parts of acrylic acid, 15 parts of an emulsion of 70% strength of a methylolmelamine alkyl ether modified with soya bean fatty acid and emulsified with turkey-red oil, 50 parts of a water-soluble methyl ether of a urea-formaldehyde condensation product, in which more than 2 mols of formaldehyde have been condensed per mol of urea, 5 parts of a yellow pigment suspension prepared by grinding 4.8 parts of dipyrazoleanthrone with 4.8 parts of dinaphthyl-methane disulphonic acid and 22.1 parts of water, and 20 parts of 10% strength formic acid.  The fabric is then squeezed on a foulard to a weight increase of 65%-80%, dried, and finally hardened at 145 DEG C-150 DEG C for 5 minutes.  In another example, 10,000 parts of a paper pulp containing 4 parts of cellulose per 100 parts of water are treated in a hollander for about 2 hours. During this period 4 parts of resin glue are added every 1/4 -hour, then 30 parts of the pigment dispersion described above and subsequently 5 parts of aluminium sulphate.

Acoustic vibrations are said to be amplified by, and a static charge produced on the surface of, a foamed thermo-plastic material mounted in contact with the cone of a loud-speaker, the cone having a depth to diameter ratio less than or equal to 0À138. The loud-speaker may be mounted with the edge of the cone in contact with the foamed material, Figs. 3, 4 (not shown), and Fig. 6. The centre of the cone may be connected to the foamed material, Figs. 1 and 2 (not shown); or the cone may be coated with foamed material, Fig. 5 (not shown). In the embodiment of Fig. 6 parts 7 and 18 are of foamed polystyrene while 17 is a sheet of acrylonitrile-styrene copolymer. An electric charge is built up when the loud-speaker is fed with a signal and this causes dust particles to accumulate on sheet 17 so allowing the loud-speaker to be used as a dusting device.

Abstract: 392,533. Thermionic valves ; generating and modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Hansell, C. W. ; Rocky Point, Long Island, New York, U.S.A.) Nov. 14, 1931, No. 31588. Convention date, Dec. 4th, 1930. [Classes 39 (i) and 40 (v).] Generators for very highfrequency oscillations comprise a valve E having two electrodes only with such a potential applied between them that electrons from the cathode F are drawn towards the grid-like anode A and some electrons pass through the anode and are drawn back as indicated at B. Oscillations of electrons through the anode A result in corresponding oscillations or interruptions of the anode current, and a circuit tuned to the frequency of these oscillations is connected between the electrodes A, F. The anode A may be planar, as shown, or cylindrical and concentric with the cathode F and bulb E. The anode A has perforations of area large compared with its own area and may be a perforated plate, a helix, or parallel or intersecting wires. The oscillations are strengthened if the anode becomes heated during operation to incandescence so that it emits electrons. The bulb E may be of glass or metal. The amplitude and frequency of the oscillations is modulated by varying the anode potential and the frequency only is modulated by a small condenser coupled to the tuned circuit, one plate of the condenser being the diaphragm of a telephone receiver carrying the modulating current. The two effects may be combined to produce amplitude modulation only.

Abstract: In the production of bent toughened glass by heating the glass and allowing it to sag on to a mould and then quenching the bent glass, a vision zone of less highly tempered glass is produced by having, during both the bending and quenching operations, an apertured sheet underneath the glass, the mass of the sheet and the spacing from the glass being such that the desired heating pattern of the glass is not <PICT:0963393/C1/1> <PICT:0963393/C1/2> <PICT:0963393/C1/3> <PICT:0963393/C1/4> affected but the quenching medium is obstructed so as to modify the degree of toughening in the zone opposed to the sheet.  The bending mould comprises a centre section 4 hinged at 3 to end sections 5 and supported in known manner on a frame 1.  The apertured sheet 7 is supported below the sheet of glass 6 on cross-bars 8 suitably shaped to allow downward movement of the centre rails 4 and welded to the frame 1. Alternatively, flat bars 8 may be secured direct to the rails 4. The sheet 7 is formed from wafer-thin heat-resisting steel and is, as shown, of oval form with a continuous outer rim 10 and spaced holes 11. In order to prevent the quenching medium passing round the edges to between the glass 6 and the sheet 7, an upstanding flange may be provided or the flange 12 may be angled as shown in Fig. 11 or a backward flange 13 may be provided, or both together. An outer fence 14 may be provided to form a channel 15 to direct the quenching medium away from the zone of the sheet and may be combined with the flanges 12, 13 alone or together, or as in Fig. 13, may have a flange 18 parallel with the flange 13, with or without the flange 12.  More than one apertured sheet 7 may be provided for more than one vision zone or they may be combined.
