Patent GB-398394-A (GB)
Title: Improvements in and relating to electrostatic precipitation apparatus
IPC: B03C3/40
Filed: 1933-01-28
Abstract: Electrostatic precipitation apparatus has a collecting electrode in the form of a flat or undulated plate having at least four lateral projections attached to it, the ends of which lie substantially on the circumference of a single circle having a discharge electrode in the form of a wire as its centre but which does not touch or cut the face of the collecting electrode.  In the case of an undulated plate, the concave <PICT:0398394/III/1> portions are circular arcs having a discharge electrode as centre. Fig. 1 shows a series of such collecting electrodes b<1>, b<2>, having projections c<1>, c<2>, c<3> co-acting with a series of discharge electrodes a<1>..a<5>.  The projections are preferably rounded or bulbous at their ends, e.g. having a diameter 10 times as great as that of the discharge electrodes.  The gas flow may be parallel to the axes of the discharge electrodes or parallel to the collecting electrodes, and the speed of flow and also the intensity of the field is reduced near the walls of the collecting electrodes, thus facilitating removal of and collection of the separated dust particles.

Abstract: 289,947. Godward, E. R. Feb. 3, 1927. Vaporizers, external.-The vaporizer is of the type disclosed in Specifications 197,984 and 258,222, and comprises a casing 1 having an inlet 10 for a mixture of fuel and air, and a cover 2 provided with mixture outlets 6. The casing is divided by a sloping wall 7 into a vaporizing chamber 8 and a heating chamber 9. The heating chamber has inlet and outlet passages 13, 14 for a heating medium such as exhaust gases and contains annular baffle plates 15 depending from the wall 7 the heating effect of which they tend to increase. The vaporizing chamber 8 contains a large number of relatively short and radially disposed plates 17 forming a number of passages for the mixture of gradually increasing area from the inlet space 10. These plates are fitted at their inner ends into slits in a central core 18 and at their outer ends are bent as at 17<b>, Fig. 4, to produce spacing means. The lower end 19 of the core 18 is of substantially conical form to assist in directing the mixture into the spaces between the plates 17 and also on to the hot wall 7. The nest of plates is secured to the cores 18 by a cover plate 20 and screw 21 an annular outlet passage 22 being left between the cover plate and the casing. The outer edges of the plates may terminate short of the casing so as to leave an annular collecting space. In a modification, the central core 18 is replaced by a rod surrounded by a sleeve into slits in which some only of the plates 16 are fitted. Instead of being straight, the plates may be simply curved, reverse curved or corrugated. In any of the forms the plates, after being secured tu the central core by the cover plate 20, are dropped as a unit into the casing 1.

Abstract: 1,263,684. Phthalocyanine pigments. CIBAGEIGY (U.K.) Ltd. 19 Jan., 1971 [23 Jan., 1970], No. 3330/70. Heading C4P. A metal phthalocyanine pigment is treated by contacting it in dry pigmentary form with a polar aliphatic solvent which is at least partially water-miscible and separating the solvent from'the treated pigment, a minor proportion of a copper phthalocyanine derivative of formula being added to the metal phthalocyanine blue pigment either before it is contacted with the solvent, during contacting or after it has been separated from the solvent. In the above formula, CuPc is a copper phthalocyanine residue, which may be chlorinated; R is a cyclic or acyclic alkyl radical having 1-20 carbon atoms or an aryl group; and R 1  is H or a cyclic or acyclic alkyl radical having 1-20 carbon atoms or an aryl group, the alkyl or aryl groups being optionally substituted, x and y are 1, 2 or 3, x + y being 2, 3 or 4. Suitable solvents include alkanols having 1-4 carbon atoms, alkyl monocarboxylates, dialkyl ketones, alkoxy alkanols and alkylene glycols. The solvent is used in an amount preferably from 5-10 parts by weight of solvent per part of pigment. The treatment is advantageously carried out at atmospheric pressure at a temperature range of 50‹ C. to the boiling point of the solvent. The copper phthalocyanine derivative of Formula I is incorporated in an amount of up to 20% by weight of the untreated pigment. The metal phthalocyanine pigment may be converted into pigmentary form by grinding it with an alkali or alkaline earth metal salt of an organic or inorganic acid, the average particle size of the resulting pigment being 0À02-1À0 micron. In one embodiment of the process, a mixture of the α and # forms of phthalocyanine blue is used, which during the process is all converted to the # form.

Title: Method of manufacturing shaped propellants
IPC: C06B21/00
Filed: 1956-02-03
Abstract: 803,275. Propellants. WOLFF & CO., KOMMANDIT - GISELLSCHAFT AUF AKTIEN. Feb. 3, 1956 [Feb. 5, 1955], No. 3518/56. Class 9(2) A method for the manufacture of shaped propellants comprises introducing a mixture, containing at least 18 per cent of water and prepared at below 18‹C., of nitrocellulose and a nitrated polyhydric alcohol into a molten organic nitro-compound or nitrate, evaporating the water by the heat of solution of the mixture in the nitrocompound or nitrate, shaping the propellant from the molten mass and solidifying the shaped propellant. 20-23 per cent water is preferred, and the nitrocellulose should have an N 2  content below 12.4 per cent and have its viscosity reduced by boiling in an autoclave. The nitro-compound or nitrate may be di- or tri-nitrotoluene, di- or tri-nitrobenzene, di- or tri-nitro phenol, trinitroglycol ether, di- or tri-nitrophenylglycol ether nitrate, tri- or tetra-nitromethyl aniline, mono- or tri-nitronaphthalene, dinitro-oxytoluene, pentanitrodiphenylamine, trinitrophenyl glycine, trinitrophenylethanolamine, dinitrodiethanol nitrate oxamide, tetra-nitropentaerythrite, dioxyethylsulphodinitrate, or mixtures thereof. The nitrated polyhydric alcohol may be nitroglycerine or diglycoldinitrate, and part may be replaced by a nitrocellulose plasticizer, e.g. dibutyl phthalate, or a urethane. The proportion of nitro-compound or nitrate to mixture of nitrocellulose and nitrated polyhydric alcohol may be 1 : 1 to 3 : 2. An emulsion of nitro-cellulose and the nitrated polyhydric alcohol is freed from excess moisture by centrifuge, comminuted, and stirred into the nitro-compound or nitrate melt at 10-20‹C. above the melting point of such compound. Water is removed from the resultant melt by applying vacuum and at such a rate that the nitrocellulose is dissolved completely. After water removal the melt temperature may be raised, e.g. 10‹C. The melt is cast and may be cooled in the mould by maintaining such a temperature, e.g. 25‹C., that gelatinized nitrocellulose having the nitrocompound or nitrate finely distributed therethrough is obtained. To reduce the setting time of the shaped product, the melt may be supercooled to below the setting temperature, when it is still plastic, and shaped just before setting, and the shaped products may be left at room temperature for a short time.
