Title: Automatic radio direction finders
IPC: G01S3/42
Filed: 1972-03-06
Abstract: 1368466 Radio direction-finders; aerials MARCONI CO Ltd 6 March 1972 [7 April 1971] 8944/71 Headings H4D and H4A An automatic radio direction finder comprises an aerial system of orientable directivity, an open aerial, means for combining signals from said aerial system and said open aerial, and means for employing said combined signals to orientate the directivity of said aerial system. There are also provided means for subjecting the signals from the orientable directivity aerial system to automatic gain control before combining them with the signals from the open aerial, and an additional member, with directivity substantially perpendicular to that of said aerial system, for supplying communication signals to a separate channel. As described, a streamlined housing 1 of insulating material, which is suitable for fitting to an aircraft, contains two mutually perpendicular loop aerials 2, 3 with ferrite cores. An open aerial is provided by a thin metal plate 4 fitted on an outside face of the housing 1. The two aerials 2, 3 are fixed, and are connected to respective stator coils 8, 9 of a radio-goniometer by leads 5, 6. The rotor of the goniometer has two mutually perpendicular coils 10, 11 and is rotatable by a two-phase motor 12 (alternatively, the loop aerials 2, 3 could be arranged to be rotatable). The coil 10 is coupled through an amplifier 13 to a balanced modulator 14. A switching oscillator 15 supplies one phase of the motor 12 and also the balanced modulator 14, output from the latter being combined with signals from the aerial 4 in a coupling amplifier 16. A mixing stage 17, with which is associated a local oscillator 18, follows the amplifier 16 and produces an I.F. signal which is fed via an amplifier 19 to an automatic direction finder detector 20 and passed to an output amplifier 21 to supply the other phase of the motor 12. Output from the detector 20 is also fed to an automatic gain control detector 22, which is coupled to the amplifier 13. Output from the goniometer rotor coil 11 is fed via an amplifier 23 to a mixing stage 24, which is also associated with the local oscillator 18. The resulting I.F. signal is fed via an amplifier 25 to a detector 26, the output of which is taken to headphones 27. In operation, the motor 12 turns the goniometer rotor so that the coil 10 is in a null position, when the gain of the amplifier 13, and the output of the coil 11 have their maximum values.

March 24, 1931, No. 9044. Convention date, March 24, 1930. Void [Published under Sect. 91 of the Acts]. [Class 110 (iii).] The buckets 6 of elastic-fluid turbines are formed with axially extending skirts 8, 9 to shield the the main fluid flow from interference by the radial flow set up in the fluid which has leaked into the interdiaphragm space. The bucket bases are formed with through passages 10 whereby the leakage currents can pass to the nozzle inlets of the next diaphragm 11 which are curved as at 12 to permit easy entrance of the leakage fluid which is directed by the skirt 9 on the outlet side of the buckets in a direction parallel with the main flow. Alternatively, the inlet skirt 8 may be provided by a strip 18, set in the diaphragm, as shown in Fig. 3, which further shows the disc rotor 20 as integral with the shaft 21.

Abstract: 891,159. Reducing pressure fluctuations. HOLMES & CO. Ltd., W. C., and THOMPSON, R. J. S. March 19, 1958 [March 20, 1957], No. 9071/57. Class 99(2). Pressure fluctuations, in a compresser system of the type wherein gas is delivered into delivery pipe means in a series of discrete volumes, are reduced by causing in a region a pressure loss in the gas stream which is devoted wholly to increasing the gas velocity to a value not less than 200 ft./sec. which pressure loss is subsequently recovered downstream of the region. In an embodiment a series of tubes 14, Fig. 1, each containing a Venturi 15, are -mounted between end plates 11, 12, inserted in a duct, the entrance and exit of which 16, 17, may be conical. In a further embodiment, Fig. 6, a number of rectangular Venturis may be mounted within a circular pipe or mounted together to form a rectangular nest. In further embodiments the Venturi may be formed within a tear-drop or conical shaped solid element, fixed or slidably mounted within a parallel, conical or Venturi shaped duct.

Patent GB-827471-A (GB)
Title: Treating titanium oxide ore
Inventor: COOPER HUGH SPENCER
IPC: C22B34/12
Filed: 1956-04-03
Abstract: <PICT:0827471/III/1> Titanium oxide ore containing iron as oxide or metal is treated with an anhydrous chloridizing gas to form and remove gaseous iron chloride and leave a titanium oxide concentrate, and the iron chloride is condensed to form anhydrous powder which is electrolysed in a fused alkali metal chloride bath through which hydrogen gas is diffused, thereby depositing iron powder and releasing chlorine for reaction in the bath with the hydrogen to form anhydrous hydrogen chloride which is withdrawn and recycled to the chlorination reactor.  The titanium ore may be ilmenite or rutile or synthetic materials containing titanium dioxide or lower oxides and in particular the ore derivative described in Specification 827,470 where the iron has been reduced to metallic form.  The chloridizing gas may be anhydrous chlorine, hydrogen chloride or mixtures thereof and temperatures of 600 DEG  to 1000 DEG  C. may be employed.  The iron chloride is condensed at 350 DEG  to 650 DEG  C. if ferrous chloride is formed or at 250 DEG  to 300 DEG  C. if ferric chloride is in question.  As shown in the Figure, titanium ore preferably pre-reduced in a furnace 1 is fed to a reactor 2 where it is treated with hydrogen chloride from vessel 23 or chlorine from vessel 22 with or without hydrogen from vessel 16, the hydrogen reacting with the chlorine in a concentric nozzle device 27 prior to entering the reactor.  Iron chlorides are removed through line 4 and are condensed in condenser 5 and passed to an electrolytic cell 7.  The latter consists of a cathode in the form of a nickel chromium iron alloy pot provided with a top 25 and a refractory annulus 10.  The anode is hollow tube 15, preferably graphite, through which a stream of hydrogen is passed from vessel 16.  The cell contains a fused mass of alkali metal chloride at 800 DEG  to 900 DEG  C. and on the addition of incremental amounts of 2 to 5% by weight of the bath of iron chloride a voltage of about 6 volts is applied.  Iron is deposited in finely granular form at the walls whilst the chlorine is converted to hydrogen chloride in the bath but out of contact with the metal walls 8.  The hydrogen chloride together with excess hydrogen is withdrawn at 18 and recycled through line 3 to the reactor, if desired with chlorine fed from vessel 22 which reacts in the nozzle 27 to form further hydrogen chloride with the excess hydrogen.  The iron free titanium oxide concentrate in the reactor 2 may be further chlorinated with phosgene, for example to produce titanium tetrachloride or it may be mixed with further carbon in amounts necessary to reduce the titanium dioxide to one of the lower oxides and heated in a hydrogen atmosphere at 1300 DEG  to 1600 DEG  C.  The reduced residue may be further chlorinated or dissolved in sulphonic acid.

Title: Manufacture of solutions of resinous condensation products
IPC: C08G12/42
Filed: 1941-07-25
Abstract: Solutions of resinous condensation products are prepared by heating together urea, melamine, aqueous formaldehyde and an aliphatic monohydric alcohol with 4 or 5 carbon atoms, in the presence of sufficient alkaline condensation agent to raise the pH of the mixture to not less than 7.5, at least until a primary condensation product has been formed, adding a sufficiency of an acid or acidic material to lower the pH to not more than 6.0, and continuing the heating until and under conditions whereby substantially all of the water present and formed during the condensation is removed by distillation.  Specified aliphatic monohydric alcohols are butanol, isobutanol and the technically available mixtures of amyl alcohols. Specified alkaline condensation agents are caustic soda, caustic potash and ammonia. Specified acid materials are phthalic acid or anhydride, maleic acid or anhydride, citric, formic and phosphoric acids.  In the second stage of the heating, removal of water may be assisted by the addition of an inert volatile organic liquid, such as toluene, xylene or white spirit, to act as an entraining agent for the water.  Examples are given.  Specifications 486,519, 486,577 and 535,408 are referred to.
