IPC: C10B27/02
Filed: 1931-08-11
Abstract: 371,723. Coke ovens : ascension pipes. STILL, C., Recklinghausen, Westphalia, Germany. Aug. 11, 1931, No. 22726. Convention date, Aug. 11, 1930.

Abstract: 1,182,000. Balers. MASSEY-FERGUSON INDUSTRIES Ltd. 17 May, 1967 [19 May, 1966], No. 22802/67. Heading B5F. [Also in Division A1] In an agricultural machine having a body supported on ground-engaging wheels including at least one drive-wheel, a power plant and crop handling apparatus, a first variable-speed drive is arranged between the power plant and drivewheel and a second variable-speed drive between the power plant and crop-handling apparatus, control means connecting the said first and second drive means whereby the speed of the crop handling apparatus is varied in response to adjustment of the first variable drive to change the ground speed. In a pick-up baler a drivewheel 4 is driven from the power plant driveshaft 6 by means of belts and a variable diameter pulley system 10, 12, 14, the shaft 16 of which is connected to a lever 18 which is adjustable by a manual control 34 to vary the effective diameter of the pulley system to increase or decrease the ground speed. The reel 38 is driven through belts 46, 48 by a shaft 40 itself driven by belt 50 from a shaft 52 driven from the main power plant by a belt 54. The belt 50 passes round variable-speed pulleys 56, 60, the movable portion 62 of pulley 60 being actuated by a shifter member 64 pivotally mounted on the machine body by a pin 66. One end of a cable 68 is connected to shifter member 64 and the other end to an arm 70 of control lever 18 whereby member 64 is pivoted in dependence on movement of lever 18. The cable 68 also passes round a pulley 76 attached to a lever 74, the position of which is adjusted by a handle 92 to determine the initial speed of the reel.

Patent GB-1142862-A (GB)
Title: Improvements relating to the starting of gas turbine engines
Inventor: BAKER ROGER CHARLES
IPC: F02C7/27
Filed: 1965-05-28
Abstract: 1,142,862. Gas turbine engines - starting. PLESSEY CO. Ltd. May 27, 1966 [May 28, 1965], No.22896/65. Heading F1G. The invention relates to a method of starting gas turbine engines in which a jet of gas under pressure is caused to impinge upon the blades of the turbine so as to bring the turbine up to sufficient speed to permit further operation of the turbine in the normal manner after ignition of a fuel and air mixture. In accordance with the invention the jet of gas under pressure is obtained by the decomposition of a monofuel under pressure. The invention is described with reference to the starting of a series of gas turbine lift engines 1, 2, 3, 4, 5, the starting gases passing from a monofuel decomposition chamber 7 to a manifold 6 and thence to starting nozzles 1a, 1b 2a, 2b &c. directed on to the turbine blades of the gas turbine engines. Monofuel such as isopropyl nitrate is supplied from tank 8 by pump 9 through shut-off valve 11 to the chamber 7. To initiate the operation a cartridge contained in breech 14 is fired, the resulting gases passing in part through line 17 to a turbine 12 which drives the monofuel pump 9, and in part through line 18 to the decomposition chamber 7 which is thus brought to a pressure and temperature suitable for decomposition of the monofuel which is supplied thereto once the valve 11 is opened. The decomposition gases then pass to the starter nozzles 1a, 1b, 2a, 2b &c., a portion of the gases passing through line 13 so that the turbine 12 continues in operation. The turbine engines are brought to overspeed before the supply of decomposition gases is shut off so that the gases are discharged from the turbines before the gases from the engine combustion equipments reach the turbines so as to prevent combustion of the decomposition gases in the turbines. The starting nozzles are inclined to the blade velocity vector at a more acute angle than the main inlet nozzles of the gas turbine as indicated in Fig. 2.

Abstract: 1483679 Frequency changing EXPERIMENTAL NI INST METALLOREZHUSCHIKH STANKOV 23 May 1975 [27 May 1974] 23009/75 Heading H2F [Also in Divisions B3 and H3] A pulse generator, e.g. for electro-erosion machining, comprises a three-phase transformer 1, the secondary windings of which are connected to a plurality of controlled rectifiers 9, 10 which are arranged to charge a capacitor 20 from the secondary or transformer 1 via a first winding 16 of an output transformer 18 and subsequently discharge capacitor 20 via a further winding 17 of the output transformer 18 under control of clock pulses so as to induce pulses in the secondary of transformer 18. As described, thyristors 9 are triggered simultaneously by a first series of clock pulses so as to charge capacitor 20 via winding 16 of the output transformer 18. Subsequently thyristors 20 are turned on simultaneously by antiphase clock pulses so as to discharge capacitor 20 via winding 17. A similar pulse is induced in the secondary 21 for each charge and discharge of capacitor 20. If thyristors 9 and 10 become simultaneously conductive, the signal developed across resistor 15 can be used to suppress the clock pulses. Smoothing capacitors 6 are connected across the secondary winding 4 of transformer 1.

Title: Improvements in or relating to the nitration of cellulose
IPC: C08B5/02
Filed: 1930-03-18
Abstract: <PICT:0357550/IV/1> Cellulose is nitrated by placing in a nitrating bath sheets of cellulose fibre paper interleaved with acid-proof spacing sheets provided with projections and recesses giving access of the nitrating acid to both sides of the cellulose sheets.  Thus, cellulose sheets 13 in the form of pure cotton fibre paper less than 1/100 in. thick are assembled vertically with corrugated aluminium spacers 14 within an aluminium box or cage 10 having perforated sides 12 and bottom 11.  After drying for about 1 hour at 100 DEG  C. the box with its contents is cooled to 15 DEG  C. and immersed for 30 minutes in a nitrating bath comprising 44,3 per cent sulphuric acid, 37,4 per cent nitric acid and 18,2 per cent of water; such bath may be made up of 2 parts of sulphuric acid of specific gravity 1,84 and 3 parts of nitric acid of specific gravity 1,42.  The box is then transferred to a series of large water baths of successively decreasing acid content and submerged for a few minutes, and is finally placed in running water.  The baths are moved up, stage by stage, for acid recovery.  After freeing from acid, the nitrated paper is stored in water or it may be used directly for making battery separators. If the paper is to be used in the dry state it is boiled in water to remove sulphates.  The aluminium spacers are replished before re-use.  Thicker and stiffer sheets may be obtained by starting with corrugated paper of, say, 10 mils.; or by inserting two or more sheets of paper between each pair of spacers.  The invention is applicable also to the production of acid-resisting varnishes. Specification 357,504, 357,505, 357,506, 357,507, [all in Group XXXVI], are referred to.

Abstract: Chrysene carboxylic acids are made by reacting a halogen chrysene with cuprous cyanide at a temperature above 200 DEG  C. and treating the nitrile thus obtained with a saponifying agent.  The products may be used as dyestuff intermediates, by reacting with aminoanthraquinones or after transformation to amino-carboxylic acids or chrysene-quinonecarboxylic acids.  In examples, (1) 2-chlorochrysene (obtained by reaction of sulphuryl chloride in nitrobenzene on chrysene) is melted with cuprous cyanide, and the chrysene-2-nitrile thus obtained saponified with caustic soda solution in an autoclave; (2) 2-bromochrysene (obtained by bromination in nitrobenzene) is treated as in (1); (3) 2.8-dichloro-chrysene (obtained by action of phosphosphorus pentachloride in boiling trichlorbenzene is treated as in (1) to give chrysene-2.8 dicarboxylic acid.  Samples have been furnished under Sect. 2 (5) of products prepared from (4) 2.8-dibromochrysene (obtained by reacting with excess bromine in nitrobenzene) by boiling with benzyl cyanide and cuprous cyanide and saponification to give chrysene 2.8-dicarboxylic acid, from 2-nitro-8-bromo-chrysene by boiling with cuprous and benzyl cyanides and reducing the nitro group to give 2-aminochrysene-8-carboxylic acid, and from (6) 2-acetoxy-8-bromochrysene (obtainable by bromination in chloroform) by boiling with benzyl and cuprous cyanides and saponification to give 2-hydroxy-chrysene-8-carboxylic acid.  Chrysene-2-nitrile may also be obtained from 2-aminochrysene by diazotization and reaction with potassium cuprous cyanide solution.  2-Chlor-8-nitrochrysene is obtained by chlorination of 2- nitrochrysene or nitration of 2-chloro-chrysene.
