Title: Azo pigments
IPC: C09B67/22
Filed: 1946-12-11
Abstract: Polyvinyl chloride or other synthetic resin, e.g. polythene, is pigmented by incorporating therein a mixture of azo pigments obtained from tetrazotized 3:31-dichlorbenzidine and tetrazotized o-dianisidine, each coupled with 1-p-tolyl-3-methyl-pyrazolone; the tetrazotized o-dianisidine forms 5-20 per cent molecular proportion of the total tetrazotized amine used.  The pigmented resin is stated to be fast to processing.ALSO:A dry yellow-red pigment powder is manufactured by isolating and drying the pigment obtained by coupling, in acid medium, two molecular proportions of 1-p-tolyl-3-methyl-5-pyrazolone with a total of one molecular proportion of tetrazotized o-dianisidine and 3 : 31-dichlorobenzidine, in which the molecular proportion of the former constitutes 5-20 (preferably 10) per cent of the total.  The coupling may be brought about by adding an alkaline solution of the coupling component to an acid solution of the tetrazotized diamines, or one of the diamines may be first tetrazotized and coupled and the second tetrazotized amine then added, or the diamines may be tetrazotized and coupled separately and the pigment suspensions mixed.  The product, which may be ground to a fine powder, may be incorporated into rubber, synthetic resins (e.g. polyvinyl chloride or polythene) or cellulose acetate.  In examples: (1) a mixture of 0.9 mol. of 3 : 31-dichlorobenzidine and 0.1 mol. of o-dianisidine is tetrazotized and an alkaline solution of 2.3 mols. of 1-p-tolyl - 3 - methyl - 5 - pyrazolone is added; (2) tetrazo solutions from 0.92 mol. of 0.08 mol. of the two diamines are mixed and a solution of the coupling component as in (1) is added; (3) an alkaline solution of 2.02 mols. of 1-p-tolyl-3-methyl-5-pyrazolone is added to a tetrazo solution from 0.88 mol. of 3 : 31-dichlorobenzidine, followed by a tetrazo solution from 0.12 mol. of o-dianisidine and an alkaline solution of a further 0.27 mol. of coupling component; (4) an alkaline solution of 0.35 mol. of 1-p-tolyl-3-methyl-5-pyrazolone is added to a tetrazo solution from 0.15 mol. of o-dianisidine, followed by a tetrazo solution from 0.85 mol. of 3 : 31-dichlorobenzidine and an alkaline solution of a further 1.9 mols. of coupling component. In each case the suspension is subsequently heated and filtered and the pigment paste washed with cold water and dried at 110 DEG  C. Specifications 441,091 and 517,456 are referred to.ALSO:Rubber is coloured in non-migrating shades fast to vulcanisation and light by incorporating therein a mixture of azo pigments obtained from tetrazotised 3:31-dichlorbenzidine and tetrazotised o-dianisidine, each coupled with 1-p-tolyl-3-methyl-pyrazolone; the tetrazotised o-dianisidine forms 5 - 20 per cent molecular proportion of the total tetrazotised amine used.

Title: Improvements relating to extrusion
Inventor: SKINNER STANLEY JOHN
IPC: B29C48/92
Filed: 1959-10-28
Abstract: 902,099. Extrusion machines. MONSANTO CHEMICALS Ltd. Sept. 20, 1960 [Oct. 28, 1959], No. 36672/59. Class 87(2). The back-pressure in a machine for extruding thermoplastic synthetic resins can be varied by changing the length of an orifice of annular cross-section situated between the screw and the die, the cross-section being uniform along the length. In the machine illustrated, resin fed from the screw 3 to the die 5 has to pass through the orifice 9 formed between that part of the passage 4 through the manifold 1 which is of reduced diameter and that part of a plunger 7 which is of increased diameter. The length of the orifice 9 is altered by screwing the plunger 7 in or out by means of the hand-wheel 11 so as to adjust the back-pressure to the minimum value which will achieve the desired degree of refining or nixing of the resin, thus minimising the power required for the extrusion operation. The plunger need not be at right angles to the screw and may, for example, be placed in line with it, or it can be integral with the end of the screw itself, The movement of the plunger may be controlled by the back-pressure through a suitable servo-mechanism. The plunger may be capable of rotation relative to the mainifold at speeds of up to 5,000 r.p.m.

Abstract: 998,846. Bending wood; wood interlays; laminates. H. F. W. LAMPE. Oct. 31, 1961 [Oct. 17, 1960], No. 36814/61. Headings B5L and B5N. [Also in Division B6] A core of a veneer or plywood surfaced laminated door or building panel comprises a number of members bent from strips of veneer, fibreboard, cardboard or plastic into a form such as is shown in Fig. 5. The strips are fed into a channel between guides 2, 3 and moved down the channel by a reciprocating plunger 4. Water is supplied to the parts of the strips where the bending lines will be by outlets from a tank 6 and, after the strips have been incised by spaced knives 5, the opposite sides of the strips are wetted at these points by knurled rollers 7 which draw water from a tank 6a. Saws 8 then trim the strips to length and they move down between a former 16 fixed to the guide 2 and a spring-loaded pressure plate 14 on a slide 11. The plate 14 presses the strip against the front of the former and then the rollers 15 on the slide turn the strip round the sides of the former and rollers 26, 27 turn it round the rear faces the former. Finally a vertical slide 28 operating in unison with the plunger 4 pushes the shaped strip down a heated tunnel formed by guides 29, 30 and the flange of the guide 30 is inclined inwardly so that it turns the free end 32 of the strip inwardly until it pushes the other free end 33 inwardly, thus ensuring that the strip retains its shape when it leaves the tunnel.

Abstract: 868,709. Space charge wave tubes. SIEMENS & HALSKE A. G. Dec. 5, 1957 [Dec. 7, 1956], No. 37926/57. Class 39(1). A space charge wave amplifier or oscillator tube comprises means for generating two electron beams in opposite directions, the paths of the electron beams converging and diverging periodically relatively to each other and the two beams interact in such a manner that a spatial harmonic component of a slow or fast space charge wave associated with one of the electron beams is coupled to a wave component (fundamental or spatial harmonic) of a fast or slow space charge wave associated with the other electron beam and travelling in the same direction as the first mentioned wave component. Thus the first space charge wave is a forward or backward wave and the second a backward or forward wave. The electron beams interact at convergent or divergent parts of their paths and energy can be extracted from either beam. The two beams may be coupled through the spaces between rods 11, Fig. 3, in a slalom electrostatic field, or by apertures in grid 17, Fig. 4, the slalom field being supplemented by a magnetic field into the plane of the paper to make the two electron beams take cycloidal paths. By reversing the direction of the magnetic field the interaction between the beams can be made to take place at the looped parts instead of at the broad curved parts of the electron paths. One of the plates 16 of Fig. 5 (not shown) can be omitted, the adjacent electron beam taking a straight path. The backward wave must be a spatial harmonic while the forward wave can be a fundamental or a spatial harmonic, examples and theory being given, e.g. first, second or third backward space harmonics in one beam and fundamental in first, second or third space harmonics in the other beam. Output can be taken from a blystron catcher resonator.
