Abstract: 1348344 Image reproduction AGFAGEVAERT AG 19 April 1971 [21 March 1970] 24880/71 Addition to 1290511 Heading G2J Apparatus, for the simultaneous but spatially separate reproduction of two or more images selected from a larger number of images recorded in superposition on a carrier 4 as diffraction gratings have different grating constants and/or azimuthal angles, comprises means for supporting the image carrier 4 means 1 for illuminating the carrier from one side with any two or more of a plurality of different beams of light, diaphragm means 3 having one or more apertures arranged to pass only first order diffracted beams, means 8-11 for selecting two or more images for spatially separate but simultaneous reproductions. The illuminating means 1 may comprise two circles of light sources whose centres are offset relative to each other and the optical axis of the apparatus. The diaphragm may have two apertures 3a, 3b. When diametrically opposed pairs of lights from circle 1a Fig.2 (not shown) illuminate carrier 4 the diffraction spectra full on aperture 3b. When opposed pairs of lights from circle are used the diffraction spectra fall on aperture 3a. Mirror system 8-11, directs the images from the apertures to separate areas of, for Example, a television camera tube 6. In a second embodiment the light sources may be arranged in two semi-circles. The diaphragm 17 Fig.3 has only one aperture 17a. The light sources in each semi-circle are each associated with a spectral filter or polarizer of that semicircle so that desired images are reproduced from carrier 16. To separate the images passing. the single aperture 17a a dichroic filter 21 is used. If desired the apparatus can be used for the reproduction of line originals having essentially two degrees of gradation. In this case a T.V. pick-up is provided with a signal amplifier to amplify all signals above a given value to the same maximum value, and to suppress all signals below a given value. Electronic image reversal may be provided. The light sources may be luminescence diodes or glow discharge lamps.

Title: Improvements in magneto electric ignition apparatus
IPC: H02K21/32
Filed: 1920-08-30
Abstract: 151,003. Bosch Akt.-Ges., R. Aug. 30, 1919, [Convention date]. Inductor machines; magneto-electric machines. -A magneto ignition machine has an armature with two or more pole-pieces so disposed at its ends that the flux traverses the whole core length in alternate directions as the armature rotates, and the pole-shoes of the bipolar magnet are so arranged that the flux traverses at least two of the armature poles at both ends of the armature simultaneously. In the form shown, the armature a, Fig. 1, has two three-limbed, preferably laminated, pole-pieces 1, 2, 3 and 4, 5, 6, one at each end, the coils w being mounted between them either stationarily or so as to rotate. The magnet pole-shoes consist of strips N', N<2>, S<3>, S<4>, having the same angular displacement as the armature poles and joined by magnetic bridgepieces t, Fig. 5, the length of which is not greater than the axial distance between the inner faces of the armature poles. These strips extend axially along the whole length of the armature. In the position shown in Fig. 1, flux enters from the pole N through the strips N<1>, N<2> into the armature poles 1, 2 and emerges at the other end at the poles 4, 6, whence it passes through the strips S<4>, S<3> to the pole S. When the pole 1 arrives under the strip S<4>, the flux reverses through the armature and there are six such reversals during a revolution. By employing armatures with more poles and providing additional magnet pole strips, the number of sparks per revolution may be increased. The field pole-pieces may be loosely mounted on the supports e and connected to the cam casing of the interrupter or the like for timing.

Abstract: Anthraquinone-acridone dyestuffs.--A polyhalogenanthraquinone-2.1 (N)-benzacridone containing at least two halogen atoms in the anthraquinone nucleus and in which the acridone ring may likewise be substituted by halogen, is condensed with two mols. of an aminoanthraquinone or a substitution product thereof.  Or an aminoanthraquinone-2.1 (N)-benzacridone containing two amino groups in the anthraquinone nucleus is condensed with two mols. of a halogenanthraquinone or a substitution product thereof.  The products, which are dyestuffs, may be carbazolized by treatment with an acid condensing agent.  Thus carbazolization may be effected by means of aluminium chloride in conjunction with sodium chloride or with pyridine, or by means of concentrated sulphuric acid or chlorsulphonic acid.  The polyhalogenanthraquinone-2.1-benzacridones may be prepared by causing a halogenanthraquinone-2.1-benzacridone containing at least one halogen atom in the 5-, 6-, 7- or 8-position to react in the known manner with chlorine or with chlorinating agents.  In examples: (1) 4.8 : Bz 2.4-tetrachloranthraquinone-2.1-benzacridone (prepared by condensing 1 mol. of anthranilic acid with 1 mol. of 1.8-dichloranthraquinone, heating the reaction product with strong sulphuric acid, and chlorinating the resulting acridone in nitrobenzene in the presence of iodine) is condensed with 2 mols. of 1-aminoanthraquinone, and the product heated in pyridine with aluminium chloride; it dyes yellowish-olive shades : (2) 4.5 : Bz 2.4-tetrachloranthraquinone-2.1-benzacridone (prepared by chlorinating 5-chloranthraquinone-2.1-benzacridone in nitrobenzene and in presence of iodine) is treated as in (1) above; the product dyes a reddish-olive shade; if the 1-aminoanthraquinone is replaced by 1-amino-4-benzoylaminoanthraquinone a product dyeing blueish-grey shades is obtained, and which, on carbazolizing by means of (i) concentrated sulphuric acid (whereby only one carbazole ring is formed), yields a violet-brown dye, and (ii) aluminium chloride in pyridine (whereby two carbazole rings are formed), yields a blackish-brown dye: (3) 4.6 : Bz 2.4-tetrachloranthraquinone-2-1 (N)-benzacridone (prepared by condensing 1.6-dichloranthraquinone with anthranilic acid, treating the reaction product with strong sulphuric and chlorinating in nitrobenzene in presence of iodine) is condensed with 2 mols. of 1-benzoylamino-4-aminoanthraquinone; the product dyes grey shades: (4) 4 : 8-diaminoanthraquinone - 2.1 - benzacridone (prepared from anthranilic acid and 1-chloro-4.8-diaminoanthraquinone) is condensed with 2 mols. of 1-chloranthraquinone and the product treated in pyridine with aluminium chloride.

Title: Method and apparatus for fractional sublimation
IPC: B01D7/00
Filed: 1965-06-15
Abstract: 1,081,579. Purification of sublimable solid substances; gas filters. MOBIL OIL CORPORATION. June 15, 1965 [July 10, 1964], No. 25277/65. Headings B1B and BIT. A sublimable solid substance is purified by vaporizing it, contacting the vapours with a cooling medium to condense the substance in the form of purified solid particles, and separating the particles from the vapours of the impurity material, in the presence of an additional coolant in gaseous form. The process may be used for separating terephthalic acid (TPA) from p-carboxybenzaldehyde, isophthalic acid or dimethyl terephthalate. The process is carried out in a tower comprising a condensing zone 28, a disengaging zone 30 provided with porous metal cartridge filters 32, and a collection zone 34, each zone being provided with a heating jacket. Crude powdered TPA, containing p-carboxybenzaldehyde and p-toluic acid as impurities, is picked up from the bottom of hopper 4 by superheated steam at 288‹C., and is conveyed through conduit 16 to coil 18 in furnace 10, where all the solid is vaporized. The vapour stream flows through filter 22 and line 24 into zone 28 at an inlet temperature of 343‹C., and is contacted with fine sprays of water at 38‹C., supplied through nozzles 52 and 54, whereupon TPA is condensed in the form of solid particles while the water droplets evaporate. Most of the p-carboxybenzaldehyde and other impurities remain in the vapour state. The walls of zone 28 are maintained at about 349‹C., by passing hot flue gas through jacket 38, in order to prevent condensation on the walls. The mixture of solids and steam descends into zone 30 where it is met by an upflowing current of cold inert gas, e.g. nitrogen or carbon dioxide, introduced into the lower part of zone 34 through pipes 72, 74, 76, 78 and 80. The gaseous phase of the suspension (i.e. a mixture of steam, gas and impurities) is withdrawn from zone 30 through filters 32 and conduits 55, 56 and 60 (conduit 56 is heated to about 280‹C. by heating-fluid in passage 58 or electrically). Filters 32 are periodically cleaned by reverse flow of inert gas from line 62. The purified TPA particles descending through zone 34 are cooled to about 93‹C., and are received in receiver 36 from which they are withdrawn from the system through valve 84. The condenser is preferably operated at pressures between 12 and 18 psia. In order to obtain a more highly purified TPA, it may be resublimed in a second stage. The gases withdrawn through conduit 60 may be passed to a secondary condenser for recovery of residual TPA. Other cooling media, which may be used instead of water in zone 28, are acetic acid, p-xylene, nitrogen, carbon dioxide, low temperature steam, and recycled purified TPA particles. Liquids or solid carbon dioxide may be introduced into zone 34 where it vaporizes to form the additional coolant.
