Title: Liquid fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1974-07-19
Abstract: 1511851 Fluid-pressure servomotor systems CAV Ltd 14 July 1975 [19 July 1974] 32018/74 Heading G3P In a fuel injection pumping apparatus, a feedpump 26 supplying a pressure in accordance with engine speed is connected to the distributer 10 through a valve 43 and a centrifugally actuated valve 32 and is also connected through a constant pressure regulator 47 and the valve 32 to a piston 63 applying a spring-load to a valve 58 regulating injection timing through a servopiston 53. The valve 43 has a loading piston 45 to reduce its output pressure. A further pressure varying with the square of the engine speed is supplied through a conduit 59 to the valve 58 and to the upper end of a spring-loaded plunger 72 which varies the distributer output through a cam surface 71 and a shuttle 19. An annular rib on the plunger 72 ensures an adequate fuel supply is maintained for starting after a manually operable stop 75 has been withdrawn. The pump 26 is also connected to the servopiston 53 and to a valve 66 which unloads the piston 63 at low speeds to cause injection to be advanced. An operator adjustable member 36 varies the load applied to a closure member 33 which acts against the forces applied to the valve 32 by centrifugal weights 38 driven by gearing from the fuel distributer. The valve 66 may be modified to connect a line leading from the centrifugal valve to the space above the piston 63 as the speed rises or it may be dispensed with  altogether and the application of pressure to the piston 63 may be controlled by a modified  plunger 72.

Title: A method of radio transmission on ultra-short waves
IPC: H04J1/00
Filed: 1931-11-23
Abstract: 370,351. Wireless transmitting systems. ARDENNE, M. VON, 19, Jungfernstieg, Lichterfelde, Berlin. Nov. 23, 1931, No. 32358. Convention date, Nov. 22, 1930. [Class 40 (v).] In order to provide an ultra-short-wave broadcasting service over a comparatively large district, a plurality of spaced transmitters is employed, each transmitter operating on a different wave-length (corresponding say to frequencies s1, s2, s3) and each modulated by a series of high frequencies (l1 .. l9) carrying the respective programmes. Thus if there are three programmes, the first is modulated on the waves l1, l2, l3, the second on l4, l5, l6 and the third on l7, l8, l9, assuming l1, . . l9 to be arranged in ascending or descending order of frequency. The ultra-short wave of frequency s1 is then modulated by l1, l4, and l7, that of frequency s2 by l2, l5, and l8, and that of frequency s3 by l3, l6, and l9. The frequencies l1 . . l9 should all lie within a single octave, and the frequencies s1, s2, s3 should be so chosen that their differences do not lie within this octave. At the receiver, programme selection is effected by tuning an ordinary broadcast receiver to the frequencies l1 .. l9, which should lie within the broadcasting band. The short-wave adapter interposed between the aerial and the receiving set may then be untuned.

Title: Improvements in mechanism for measuring and marking warps in sizing machines
IPC: D06B3/04
Filed: 1919-12-29
Abstract: 160,915. Blackburn Loom &. Weaving Machinery Making Co., Ltd., and Watson, R. Dec. 29, 1919. Yarns, marking and measuring. - Relates to warp-sizing machines having automatic means for measuring the warps and marking them in shawl lengths, and consists in special means for marking them to indicate to the weaver the cuts, tab ends, and the " gauled-up " lengths between adjacent tab ends. At the end of each cut of shawl lengths, the usual motion is thrown out of gear and the measuring-roller causes a rack carrying adjustable hammer-operating means to be traversed to effect the marking of the tab ends &c. At the end of the cut, a projection 21, on the hammer-lever 20 engages an inclined projection 19a of a lever 19 to turn a shaft 18 having a lever 17 connected by a link 16 to a weighted lever 13, which normally supports the tapered end of a lever 5 on the shaft 3 of the measuring-roller 2. A gear-wheel 8 carried by the lever 5 and in gear with the measuring- roller is thus allowed to fall and mesh with a slidable rack 9 to traverse it to the left. While the wheel 8 is falling, the gear-wheel 12 of the usual motion is thrown out of gear with the measuring-roller by a projection 5a of the lever 5 adjustably linked to the usual gear-lever 10 carrying a wheel 12a, which is normally driven from the measuring-roller and drives the gear-wheel 12. When the rack is traversed, an adjustable inclined block 28 on the rack engages a striking-plate 30 to operate a tab-marking hammer, and a similar inclined block 29 engages a projection 38 to operate another marking-hammer. At the end of the traverse of the rack, an adjustable block 22 on the rack engages a flange 8a of the wheel 8 to move it out of gear with the rack and to turn the lever 5 to restore the lever 13 into the position shown, and to bring the gear-wheel 12 of the usual motion into gear with the measuring-roller. The rack is moved to its normal position by a drum 23 geared to the underside of the rack and having a weighted cord 24 wound upon it. The cut length is determined by a worm-operated bellwheel which can be slid into engagement with a second worm-wheel to double the cut length as inquired without altering the shawl lengths between the cuts. The means for controlling the rack described in the Provisional Specification differ slightly from those described above.

IPC: C09K11/66
Filed: 1955-11-17
Abstract: 842,084. Luminescent materials. BRITISH THOMSON-HOUSTON CO. Ltd. Nov. 5, 1956 [Nov. 17, 1955], No. 32992/55. Class 39(1). A luminescent material consists of a solid solution of zinc and barium silicates activated with lead, the molecular proportion of zinc silicate to barium silicate lying between 4 : 1 and 1 : 10, and the material when subjected to excitation by short ultra-violet radiation emitting radiation in the range 3000 Š to 3100 Š. The molecular proportions of ZnO: BaO: SiO 2  used in the starting material are preferably such that the constituent silicates in the zincbarium silicate are substantially zinc orthosilicate (Zn2SiO4) and barium disilicate (BaSi2O5). The more efficient phosphors result from proportions lying in the range between 1Zn 2 SiO 4  :2BaSi 2 O 5  and 2Zn 2 SiO 4  : 1BaSi 2 O 5 , the most efficient resulting from proportions near the 1 : 1 ratio. The materials are fired two or three times during preparation, and formation of the phosphor is assisted if a fluoride is present during the first firing and a chloride is added before subsequent firings. Lead fluoride (PbF2) is preferred as the source of both lead and fluorine, the initial amount of PbF2 added lying between 1“% and 5% per total mols of ZnO + BaO (or their equivalents), and being preferably 2¢%. Alternatively, equivalent amounts of PbO (or other Pb compounds that decompose to form PbO) and BaF2 may be used. BaCl2 2H2O is preferred as the source of Cl, but other chlorides, e.g. ZnCl2 may be used. The BaSIsO5 is preferably prepared in precipitate form, but may be prepared from BaCO3 and SiO2. The phosphor is suitable as a coating on the inside of the envelope of a fluorescent low pressure mercury vapour lamp for therapeutic purposes.

Title: Production of toluylene diamine
IPC: C07C209/36
Filed: 1954-11-15
Abstract: 2 : 4- and 2 : 6-toluylene diamines are prepared by hydrogenating 2 : 4- and/or 2 : 6-dinitrotoluene in a continuous manner in the liquid phase at a temperature of from 80 DEG  to 120 DEG  C. and at a pressure above 50 atmospheres in the presence of Raney nickel. Methanol or ethanol may be used as a diluent.  In place of the dinitrotoluene starting material, a mixture of dinitrotoluene and toluylene diamine may be used.  In an embodiment of the invention, a solution of dinitrotoluene in methanol containing Raney nickel is continuously pumped co-currently with hydrogen through a reactor at a pressure of about 200 atmospheres and a temperature of from 80 DEG to 120 DEG  C., the unused hydrogen being recycled.  The methanol solvent is removed and the residue worked up by distillation.  In a further embodiment, a eutectic mixture consisting approximately of 76 per cent dinitrotoluene and 24 per cent toluylene diamine diluted with methanol is hydrogenated.  Eutectic mixtures may be obtained by mixing a calculated quantity of fresh dinitrotoluene and methanol with a portion of the aqueous methanolic solution of toluylene diamine obtained from a previous hydrogenation.  Examples illustrate the continuous hydrogenation at 150-200 atmospheres and 100 DEG  C. of (1) dinitrotoluene in methanol; and (2) a mixture of dinitrotoluene and recycled toluylene diamine in aqueous methanol.
