Title: Improvements in and relating to Means for Sychronizing the Firing of a Gun with the Rotation of a Propeller upon Aeroplanes.
IPC: F41A19/05
Filed: 1917-07-14
Abstract: 128,283. Sopwith Aviation Co., and Kauper, H. A. July 14, 1917. Addition to 126,392. Fire between aircraft propeller blades, controlling and synchronizing.-Relates to devices of the kind comprising a cam rotated by the propelling engine and a spring for firing the gun when the cam permits, as described in the parent Specification. According to the invention, means are provided for holding the firing spring out of action when compressed. In the form shown, the firing spring a is secured at its ends to two parts b, b<1> of a spindle provided with slots h and lugs f respectively, which, when in alinement, allow the gun to fire and, when out of alinement, prevent firing. The part b is connected by linkwork to the firing lever w and to the tappet y of the controlling cam x. The part b<1> is free to rotate and slide in a bearing c, and is provided with a crank d actuated from a distance by a Bowden wire e and with teeth d' adapted normally to snap into recesses c<1> in the bearing c and to hold the part b<1> in the position where firing is prevented. The part b<1> is. urged into that position by the torsion of the spring a as soon as the slots h release the lugs f during its actuation by the cam x. This rotation of the part b<1> is limited by shoulders m on the part b. The spring s holds the tappet y away from the cam while the gun is thus put out of action. To fire the gun, the part b is rotated by a pull on the Bowden wire until the lugs f are opposite the slots h, and to cease fire, the pull on the Bowden wire is released, allowing the torsion of the spring a to restore the part b<1> to its normal position.

Filed: 1975-05-23
Abstract: 1489081 Cigarette making machines MOLINS Ltd 23 May 1975 [7 March 1974] 10349/74 Heading A2C In a cigarette making machine the quantity of tobacco in a tobacco stream is regulated by depositing varying amounts of tobacco on the tobbacco stream from an electrostatic conveyor. As shown tobacco 10 that has been removed from the stream by a trimmer 6 is charged by the plates 12, 14 of an electrostatic generator. The electrostatic conveyor 16 is charged in the opposite sense by a plate 18 so that it attracts the charged tobacco. An internal earthed plate 20 leaks away charge from the conveyor so that tobacco may be deposited on the tobacco stream 4. The charges on the plates 12, 14 and 18 are varied in response to a signal obtained from an air cell 22.

Title: Method of extraction of vanadium from bauxites and manufacture of ferro-vanadium
IPC: C22B34/22
Filed: 1945-05-01
Abstract: Relates to the extraction of vanadium from salts crystallizing from Bayer liquors consisting of sodium fluo-vanadate, fluo-phosphate and fluo-arsenate.  The salts are dissolved in hot water, sulphuric or phosphoric acid is added for partial or complete neutralisation employing phenol-phthalein, and crystals of disodium phosphate, disodium arsenate and in some cases, sodium sulphate allowed to separate.  The filtrate is treated by one of three methods: (1) Ammonium chloride or sulphate is added to precipitate ammonium metavanadate which is calcined in a closed vessel to produce V2O4 and V2O3; (2) Gaseous ammonia is introduced to precipitate all sodium salts other than the vanadate.  The ammoniacal filtrate is thereupon (a) partially degassed by heating, and sulphuric or hydrochloric acid added to precipitate pure ammonium metavanadate, or (b) completely degassed, and sulphuric acid added to precipitate a sodium salt of hexametavanadic acid on heating to 100 DEG  C. for some hours; (3) An aluminium salt is added in the presence of sulphuric acid to remove the fluorine as cryolite; calcium sulphate is added to the filtrate to precipitate calcium phosphate, on removal of which, sulphuric acid and sodium chlorate are added.  After some hours at 100 DEG  C. disodium hexametavanade precipitates.  The calcium phosphate may be converted to phosphoric acid for use at the commencement of the process.  The various sodium salts crystallizing in the above processes may be neutralized with sulphuric or phosphoric acid, disodium phosphate crystallizing from the cooled liquor.  The mother liquors from recrystallizations of the phosphate, when rich enough in arsenic, are treated with caustic soda, trisodium fluoarsenate, for use in the manufacture of insecticides, crystallizing.  The solution is then treated for the recovery of the vanadium as described. Ferrovanadium is obtained from the vanadium oxides, &c., produced (see Group II).  The slags from this process are roasted at 700 DEG C., with the addition of sodium carbonate when necessary, to produce sodium vanadate, convertible if desired, to ammonium metavanadate.ALSO:Ferrovanadium containing say 50-60 per cent V and less than 0.1 per cent Al is produced by the reduction with powdered aluminium in the presence of iron of the lower oxides of vanadium. Thus there may be employed V2O4 containing up to 10 per cent V2O3 obtained by calcining ammonium metavanadate in a closed vessel. Disodium vanadate, partly reduced by coal, sawdust, &c. at 800-1,000 degrees C. may also be reduced by aluminium in the presence of iron.
