Title: Improvements in or relating to aircraft having tunnel-shaped wings
IPC: B64C39/06
Filed: 1957-03-15
Abstract: 819,226. Aircraft. ZBOROWSKI, H. P. G. A. R. VON. March 15, 1957 [March 16, 1956], No. 8554/57. Class 4. [Also in Group XXV] An aircraft has a tunnel shaped wing and propulsion means comprising an airscrew within the wing and a power plant mounted outside the wing by quick release fastenings, the drive from the power plant to the airscrew incorporating an easily disconnected coupling, so that the power plant may easily be separated from the aircraft. The aircraft shown has a cylindrical annular wing 1 with control surfaces 4, spaced from a concentric fuselage 2 by struts 3. Each of two diametrically opposite gas-turbines 6 is enclosed in a nacelle 7 secured to the exterior of the wing by two quick release fastenings 16 (see Group XXV), interconnected so that both operate together. The power take-off shaft 8 of each turbine drives through bevel gears 10, 11, and countershaft 13 having a universal joint 13a near the nacelle and a universal joint 13b near the gear box 9 driving contro-rotating propellers 5. Each countershaft is formed in splined telescopic sections, so that when the fastenings 16 are released, the nacelle together with the engine and gears 10, 11 can be withdrawn. Specification 730,069 is referred to.

Title: Process for the manufacture of 5-iodo-2-amino-pyridine
IPC: C07D213/73
Filed: 1928-03-21
Abstract: 288,571. Schering-Kahlbaum Akt.- Ges., April 12, 1927, [Convention date]. 5-Iodo-2-aminopyridine is prepared by treating 2-aminopyridine successively with quantities of an iodizing agent which separately are insufficient to effect complete conversion into the addition compound and decomposing the said compound with alkali after each addition. According to the examples, 2-aminopyridine is treated with a small quantity of iodine or iodine chloride and the resulting iodide or chloriodo compound decomposed with caustic potash; after acidification, further quantities of iodine or iodine chloride are added and the product again decomposed with alkali a third treatment produces 5-iodo-2-aminopyridine. Specifications 246,501, 246,842, 264,508 and 283,576 are referred to.

Filed: 1975-03-06
Abstract: 1476700 Ventilators H G BAUS 6 March 1975 [8 March 1974] 9449/75 Heading F4V [Also in Divisions E2 and F1] A ventilator comprises an octagonal casing formed by a fixed casing part 2 disposed in a wall 26 hingedly connected to a closure member 4. An air guide casing 200 having two radial walls 77, 83, two support walls 79, 81 and two air flow nozzles 96, is positioned in the casing 2 and is shaped to match the inner surface of the casing 2. The air guide casing houses two  blowers 50, 54 located on either side of a motor block 56. The blowers suck air in axially through apertures 76, 78 in the casing walls and blow it out radially. The casing 200 also includes a holding strip 84 which is snap-fitted into a groove 90 in the casing part 2. A lower rear inclined surface 16 of the casing part 2 includes openings (30, Fig. 8), 32 directly adjacent the nozzles 96. Upon installation of the ventilator, when the air guide casing 200 is fitted into the housing part 2, electrical contacts 108, 110 of the motor 56 engage in current conductor grooves 100, 102 and with the respective conductors 104, 106. Stiffening rods (116, Fig. 13) may be inserted in corresponding grooves 118, 120 in the casing part 2. The grooves also hold an assembly plate 122 for a pull-actuating device 64 for the closure member 4. In operation of the ventilator for exhausting room air, the blowers 50, 54 suck air from the room through openings 76, 78 and eject the air radially through the nozzles 96 and the corresponding openings 30 and 32. In operation of the ventilator for the introduction of fresh air into the room (Fig. 12, not shown), the ventilator is modified in that the nozzles 96 (97, Fig. 12) close off the openings 30, 32, external air being drawn in through openings axially displaced from the openings 30, 32 en route to the impellers 50, 54. The air guide casing 200 is also provided with air outlet openings (123) facing the closure member opening 92 and with air guides (134, 136, Fig. 12) (138, Fig. 13) which prevent the air from the room from being sucked into the impellers 50, 54.

Patent GB-803158-A (GB)
Title: Extraction process for hydrocarbons
IPC: C07C7/11
Filed: 1957-03-22
Abstract: Olefines are separated from other hydrocarbons by selective solution in an aqueous-alcoholic ammoniacal cuprous salt solution, the alcohol being methanol or ethanol or mixtures thereof.  The process is particularly suitable for the separation of butadiene from other C4 hydrocarbons containing 10-95 per cent by weight butadiene or for the purification of butadiene.  Suitable cuprous salts are the sulphate, acetate, lactate, tartrate, formate, nitrate, carbonate, chloride, fluoride, glycollate, benzoate, salicylate, benzene sulphonate, orthophosphate, cyanide, thiocyanate and maleate.  The solutions may be prepared by digesting copper shot with the aqueous-alcoholic ammonium salt with added oxygen or air or the cuprous salt with aqueous-alcoholic ammonia.  A trace of cupric salt is preferably present.  Countercurrent extraction or a multi-stage mixer-settler train can be used.  The absorbed olefine is regenerated by heating the solution under reduced pressure.  Suitable methanol-acetate solutions contain 30 per cent by weight methanol, 2.5-3.5 mols. cuprous copper, 0.15-0.4 mol. cupric copper, 3-6 mols. acetic acid and 9-14 mols. ammonia per litte of solution, while a methanol-cuprous formate solution may contain up to 40 per cent by weight methanol, 2.5-6 mols. cuprous copper, 0.15-0.4 mol. cupric copper, 3-8 mols. formic acid and 9-18 mols. ammonia per litre.

Title: Improvements in the purification or production of titanium
Inventor: ROSTRON DOUGLAS WALTER
IPC: C22B34/12
Filed: 1955-04-01
Abstract: Partially oxidized titanium and/or titanium scrap metal is purified by mixing it with calcium particles of a size passing through a 4 mesh screen and in amount at least 100 per cent in excess of that required to remove oxygen and optionally with up to 150 per cent by weight of calcium chloride, heating the mixture in an inert atmosphere to at least 1000 DEG C to remove oxygen and separating the superficially adhering scale from the resulting mass by abrasion or by acid or molten salt treatment or by a combination of these means. The scale may be removed by leaching in hydrochloric acid at a temperature not exceeding 25 DEG C., grinding the mass in water, separating the purified metal and agitating in dilute hydrochloric acid at a temperature not over 25 DEG C.  Any hyrogen absorbed in the metal may be removed by crushing the metal to powder, compacting and then sintering.  The partially oxidized titanium may be that produced by reduction of titanium dioxide with magnesium particles of a size passing through a 4 mesh screen and in an amount at least 100 per cent of that required to reduce the dioxide and mixed with particles of magnesium chloride in amount not less than 40 per cent by weight of the dioxide, the mixture being heated to a temperature not less than 1000 DEG C. to give a product containing at least 90 per cent titanium.  Preferably the reaction mixture is covered with dry lime before heating.  The product may be separated and crushed and leached in hydrochloric acid before the purification reaction with calcium.

As illustrated in Fig. 2 the microphone 18 is supported in a casing 12 which may be secured by bosses 14 to the window of a shop or to a wall adjacent the window. Coins inserted in a slot 17 operate a suitable coin-freed mechanism controlling the circuits of a recording .apparatus and timing means to which the apparatus within the casing is connected by a conduit 21. An indicator, such as a lamp, carried by the casing indicates whether the device is available.
