Title: Improvements in the manufacture and production of nitrogenous condensation products
IPC: C07D221/18
Filed: 1932-12-28
Abstract: Pyrbenzanthrones are prepared by reacting acrolein, its homologues or substitution products or compounds capable of reacting as acrolein in an acid medium with compounds of the general formula <PICT:0412586/IV/1> wherein a further benzene nucleus is condensed with the benzene nucleus shown in two vicinal positions marked X, wherein Y stands for --OH or = O and n for 1 or 2, and if desired, halogenating, nitrating or sulphonating the products.  Compounds capable of reacting as acrolein are glycerine or its esters, or epichlorhydrin, and suitable pyridinonaphthalenes are 3 - oxy - 1(N),2 - pyridinonaphthalene, 1(N),2 - naphthoquinoline - 3,4 - quinone (from 1 - naphthoquinoline by oxidation with chromic acid), pyranthraquinone and derivatives thereof containing alkoxy, alkyl, aryl, nitro, cyano groups or halogen, such as 3-oxy-Py2-methyl-1(N),2-pyridinonaphthalene (prepared by melting 1-naphthoquinaldine-3-sulphonic acid with caustic alkali); a sulphuric acid medium is preferred with temperatures of 100--160 DEG C.  In examples: (1) 3-oxy-1(N),2-pyridinonaphthalene is reacted with glycerine in sulphuric acid solution and in presence of sodium nitrobenzene-sulphonate to give 8(N)-1,9-pyrbenzanthrone; similar treatment of 3-oxy-Py2-methyl-1(N),2-pyridinonaphthalene yields a methyl-8(N)-1,9-pyrbenzanthrone, and pyranthraquinone yields an isomeric pyrbenzanthrone to the above (using aluminium or iron powder in place of nitrobenzenesulphonate), 3,8 - dioxy - 1(N),2-pyridinonaphthalene (prepared by a Skraup's synthesis on 8-oxynaphthylamine - 3 - sulphonic acid followed by fusion with caustic alkali) yields 8(N) - Bz3 - oxy - 1 - 9 - pyrbenzanthrone, 3-oxy - Py2-oxy - 1(N),2 - pyridinonaphthalene (prepared by melting 1-naphthoquinoline-3-sulphonic acid with caustic potash at 280--300 DEG  C.) yields 7-oxy-8(N) - 1,9 - pyrbenzanthrone, 3 - 6 - dihydroxy - 2 - naphthoquinoline (prepared by fusing 2-naphthoquinoline-3,6-disulphonic acid with caustic potash at 250--270 DEG  C.) yields Bz1-oxy-5(N)-1,9-pyrbenzanthrone; (2) 8(N)-1,9-pyrbenzanthrone is brominated in presence of iodine and iron to give a monobromo derivative and the isomeric pyrbenzanthrone and methyl derivative of 8(N) - 1,9 - pyrbenzanthrone referred to above may be similarly brominated; using higher temperatures (170--180 DEG C.) a dibromo derivative is obtained; chlorinating in trichlorbenzene in presence of iodine yields a di- and trichloro derivative, while bromination and chlorination in either order yields chlorbromo derivatives; an iodo derivative is prepared by iodination in concentrated sulphuric acid; (3) 8(N) - 1,9 - pyrbenzanthrone on nitration in nitrobenzene yields a mononitro derivative probably a Bz 2-nitro derivative converted by aqueous sodium sulphide to an amino body; (4) 8(N) - 1,9 - pyrbenzanthrone is sulphonated with fuming sulphuric acid at 90--100 DEG  C.

Patent GB-1589843-A (GB)
Title: Sound-reducing structural element
IPC: E04B1/82
Filed: 1977-09-02
Abstract: The section of a sound-insulating, wall-like component (20), as may be used, for example, for air-intake lines of internal-combustion engines, comprises a base plate (22) on which there are arranged, in the conventional manner, cuboids (24) and (25) of different dimensions, but of the same height. This construction is based on the knowledge that sound insulation of a rigid wall is always low when the track wavelength of an incident planar wave and the bending wave velocity in the wall coincide. A wall-forming component of this type ensures, by virtue of this design of the wall cross-section, a considerably improved airborne-sound insulation. This component is suitable, in particular, for producing air-intake tubes and other engine components which are intended to shield areas with a high degree of airborne sound from the exterior. <IMAGE>

Abstract: 346,456. Copying telegraphy. EHRENHAFT, F., 2, Nassauischestrasse, Wilmersdorf, Berlin. Oct. 29, 1929, No. 36945/30. Divided application. [Class 40 (iii).] Combined sound and picture records are transmitted to a distance by scanning the sound and picture records separately at a speed less than the speed of television and separately recording the sound and picture signals at the receiver. Fig. 3 shows a known receiver wherein both the sound and picture signals received at 20 modify, through a Kerr cell, light from the source 21 which records on the film 27 by a single rotating scanning device 23 with mirrors 22, 24 and lens 25, the film moving to supply the other component of scanning. The film enters developing and fixing tanks 32 and 33 and may pass to a projector 34. This apparatus is modified in Fig. 6 by the addition of a separate scanning device spaced from the other and recording only the sound signals. The rotating device 83 records the pictures, while light from the source 90 is modified by the sound signals to simultaneously record the sound. The film and the scanning device are driven by a motor 93. The movement of the film provides the scanning movement for the sound recorder. The apparatus at the transmitter is substantially the same. The sound record is preferably more finely scanned than the picture. The sound record scanning device may also rotate like the picture scanning device and the sound may be recorded on a separate carrier.

Title: Improvements in or relating to the separation of zirconium and hafnium compounds
IPC: C01G25/04
Filed: 1957-11-28
Abstract: <PICT:0833103/III/1> Zirconium and hafnium tetrachlorides are separated from mixtures thereof by subjecting the mixture to fractional distillation in a fractionating zone, in which the temperature of the hot end of the zone is in the range 455 DEG  to 520 DEG  C., and the absolute pressure is not less than 97% or more than 103% of that indicated by the equation: <FORM:0833103/III/1> where Pmm Hg is the pressure in millimetres of mercury, and TK DEG is the absolute temperature of the hot end of the zone. The pressures corresponding to this formula range from 5.69 X 104 mm. Hg to 2.23 X 104 mm. Hg.  Zirconium tetrachloride of reduced hafnium content is removed from the hot end, and enriched hafnium tetrachloride from the low temperature end.  The process may be carried out in a column of at least 30 theoretical plates.  The temperature at the hot end being between 460 DEG  C. and 512 DEG  C. and the still head above the column being cooled to not below 440 DEG  C. to provide a liquid reflux, pure hafnium tetrachloride being recovered from the top of the column and pure zirconium tetrachloride from a lower part.  In an example (illustrated by Fig. 2), an impure zirconium tetrachloride, containing 1.6% hafnium tetrachloride, was introduced into the boiler 24 in an argon atmosphere, and then argon was introduced into the whole system to a pressure of about 19,400 mm. Hg.  The whole system was then heated, and the column 17 and boiler 29 were filled with halide vapour and some liquid, the argon being removed via valve 7. The pressure in the system was maintained at 28,180-28,440 mm. Hg by heating the boiler 29 by means of heater 33.  The top of the column is maintained at about 440 DEG  C., and a continuous separation may be achieved, pure zirconium tetrachloride being withdrawn either as liquid through 26 or as vapour through 30, and a fraction rich in hafnium collected in 14a or withdrawn via 14b.  The condenser 8 provides a reflux liquid for the column, and the hafnium fraction is condensed by condenser 9.  The whole apparatus is jacketed so that suitable temperature controlling liquids, such as molten salts, may be circulated.

Filed: 1956-12-14
Abstract: 839,576. Combined sound and picture apparatus. RITTER, E. Dec. 14, 1956 [Dec. 16, 1955; Dec. 4, 1956], No. 38297/56. Class 40 (2). [Also in Groups XV and XVI] In an educational appliance in which a text e.g. a foreign language is continuously fed across a field of view, a phonograph is coupled thereto so that sound corresponding to the text may be heard and control means are provided for interrupting the feed for independent repetition of a selected portion of the text. The phonograph comprises a lower section 42 of the appliance which has a front opening slot 43 for slipping in a record. When the record is positioned, a key on the front of the apparatus is operated and a rotatable plate 44, Fig. 9, lifts the record, which is centred by a cone 160, to a drive plate 159 rotated by a friction plate 78 to which, at adjustable radii, is a motor-driven wheel 75. The pick-up arm 45 of the phonograph may be accurately positioned for starting and automatically lifted clear of the record for returning to starting position by the mechanism shown in Fig. 10 and Fig. 2. To raise the pick-up arm 45, a slide 95 associated with the educational appliance, is shifted and a bent portion 180, Fig. 10, engages an axis 172 whereupon a sector plate 173 depresses an end 46 of the pick-up and the stylus 151 is lifted clear of the record 150. At the same time the slide 95, by means of a pin 182, rocks a lever 185, rotates the axis 172 and a notched end 174, now in lowered position, rotates the arm back to starting position. This may be determined by an arm 193, Fig. 2, having a rocking lever 189 coacting in set position with a latch 188 which during playing of a record is raised clear of the lever 189. The record may be ejected by a key-operated lever which acts on the edge of the record.
