Title: Transmission for rail vehicles driven by an internal combustion engine
IPC: C07D475/10
Filed: 1961-08-09
Abstract: 944,350. Change-speed gears. C. SCHULERVOITH, M. VOITH, H. W. SCHWEPPENHAUSER, and C. KNAPP, [trading as VOITHGETRIEBE KOMM. - GES.]. Aug. 9, 1961 [Aug. 9, 1960], No. 28794/61. Heading F2D. In a transmission for a rail vehicle driven by an internal combustion engine and comprising an hydrodynamic torque converter followed by a mechanical reversing gear, in order to avoid operation of the mechanical reversing gear during shunting operations, the mechanical reversing gear is preceded by a further hydrodynamic torque converter which drives the input shaft of the reversing gear in the opposite direction to the first torque converter. As shown in Fig. 1 a driving shaft 2 is fast with the impellers of torque converters 3, 4 and an hydraulic coupling 5, the torque converter 4 and coupling 5 driving a shaft 9 through gears 10, 11 and the torque converter 3 driving the shaft 9 through gears 6, 7 and an idler 8. The shaft 9 forms the input shaft of a reversing gear 18. The torque converters 3, 4 give the same low speed ratio range and are used to give forward and reverse during shunting operations, the torque converter 4 is filled to give a low speed ratio range during main line working, and coupling 5 is filled to give a high speed ratio range, the reversing gear 18 being used for reverse drive during main line working. Instead of using a reversing idler 8, the torque converter 3 may be designed with a reversely rotating turbine. The hydraulic coupling 5 may be replaced by a cone friction clutch. In the embodiment of Fig. 3 the coupling 5 is replaced by a torque converter 49; with a dog clutch 57 in its left-hand position the turbine of a torque converter 47 is geared through a reverse idler 51 to the input shaft 55 of a mechanical reversing gear 60, and shunting can be carried out by filling and emptying torque converters 47 and 48. In the right-hand position of the clutch 57 the torque converter 47 is geared to the shaft 55 through gears 53, 54 to provide an extra range of forward speeds for main line working.

Title: Method of making clay pipe
IPC: B28B21/18
Filed: 1965-07-07
Abstract: 1,094,819. Molding clay pipes. PACIFIC CLAY PRODUCTS. July 7, 1965 [May 6, 1965], No. 28861/65. Addition to 977,373. Heading B5A. In a method of moulding a clay pipe between a central mandrel and a surrounding elastomeric sleeve as described in Specification 977,373, a void is left at the top of the moulding cavity so that upon release of the moulding pressure the pipe may expand in an axial direction, which expansion dissipates deleterious stresses. In an embodiment, not shown in the parent case, the compression chamber is formed between a mandrell 20, fixed, by means of an upper pipe 119, to a mounting 123 carried by fixed mould block 130, and a hydrostatically actuated resilient sleeve 122 carried within said mould block. Slidable within the pipe 119 is a feed tube 139 carrying a hopper 145, which tube is joined by bolts 141 passing through slots in pipe 119, to a sleeve valve 131 which is therefore slidable within block 130. The lower end of the compression chamber is closed by a vertically reciprocable member 142. In operation, valve 131 is raised to clear ducts 159 in the upper end of mandrel 120 thus allowing material to be fed from hopper 145 to the compression chamber. Air is then exhausted, to facilitate packing; through channel 161 in the valve and channel 163 in the block 130, and the pipe moulded by sleeve 122. The pressure is then released, the pipe allowed to expand radially and axially, and then withdrawn by lowering member 142.

Abstract: 533,344. Centrifugal machines. SERRA, F. SALSAS-, and TECHNO-CHIMIE. Oct. 31, 1939, Nos. 29041 and 29042. Convention dates, Dec. 14, 1938, and June 9, 1939. [Class 23] An atomizing apparatus for liquids has a rotating wheel 3 to the central ring 6 of which the liquid is fed, and a surrounding wall forming n toothed impact surface 1 on which the liquid is thrown ; an upward current of air or other gas carries away the finer liquid particles. The wheel is provided with radial channels 4 and a flat zone at its periphery so that the liquid forms a sheet before leaving the wheel. This sheet strikes the teeth 2 and is consequently broken up. The teeth may be parallel to the axis of the wheel or be inclined forwards or backwards with respect to it. In the form of machine shown in Fig. 5, three disc wheels 3, 3a, 3b are rotated by the motor 7 and they throw liquid against the toothed surfaces 2, 2a, 2b, A bell shaped compartment 16 encloses the lower end of the tubular shaft 14 and rotation of the shaft causes liquid from the tank to rise inside the bell 16 to the level of 'the openings 18 so that a constant level is maintained. A helical thread 13 raises the liquid through the channel 14 to an adjustable discharge point 19, from which it passes over the top wheel. Air is admitted to the casing by apertures 10, controlled by a movable band 9, and is moved upwards by the fan 8 to entrain the atomized liquid. This stream is then discharged through a space containing truncated conical screens 11, 12 the latter of which is stationary while the former can be adjusted in position relative to the latter. In a modification the toothed impact wall may be rotated and in another modification successive throwing wheels may rotate in opposite directions. Radial fan blades in the discharge path may be employed to throw out large size liquid particles.

Abstract: 945,730. Irradiation apparatus. CHEMISCHE WERKE HULS A.G. July 30, 1962 [July 31, 1961], No. 29117/62. Heading H5R. [Also in Division G1] A method of quantitatively determining an element in a liquid or gaseous medium comprises irradiating the medium with the characteristic X-ray spectrum of an element excited by α- or #-rays and having an atomic number exceeding that of the element to be determined by at least 2, and measuring the specific absorption in the region of the K- or L-absorption edge of the element to be determined. To determine cobalt in benzene, the mixture is passed through a cell 2. An α- or #-ray emitting preparation 6 in a solid filler 5 is pressed against a copper foil 7 which produces X-rays at 1.53Š and 1.38Š which are in the strong absorption edge of cobalt. The radiation passing through the mixture is received by a NaI-Tl scintillation crystal 8 coupled to a photomultiplier by a light conductor 9, and the output is fed to a single channel pulse height analyser 10 and indicator 11. The detector system may be stabilized against sensitivity variations by measuring the height of the pulses produced and controlling the detector H.T. supply to maintain the pulse height constant. The radioactive source may be H<SP>3</SP>, C<SP>14</SP>, Sr<SP>90</SP> or Ni<SP>63</SP> for #-rays or Ra<SP>210</SP> for α-rays.

Abstract: 1465511 Phthalimide BASF AG 4 July 1974 [6 July 1973] 29607/74 Heading C2C A continuous process for preparing phthalimide comprises reacting phthalic anhydride with ammonia, flowing in countercurrent at elevated temperature and in a molar ratio of 0À9 : 1 to 1À1 : 1. The offgas formed in the reaction is preferably scrubbed with aqueous ammonia solution. In a preferred embodiment scrubbing is carried out continuously and countercurrent in a column. The washing solution is introduced into the top of the column, conveniently through a spray means or spray nozzle. The off-gas enters into the bottoms in the column. The washing liquid collecting in the bottoms after the scrubbing is conveniently drawn off continuously, some of it, advantageously from one third to one half of the total amount being returned to the top of the column with fresh washing solution and the remainder being supplied to an evaporator. The washing liquid is continuously concentrated in the evaporator, and the mixture of steam and ammonia formed is conveniently supplied to the ammonia scrubbing. It is advantageous to regulate the amounts of recycled washing liquid, freshly supplied aqueous ammonia and ammonia and water supplied from the evaporator so that the offgas is continuously scrubbed at a pH of from 10 to 13 in the washing solution. From 20 to 40% by weight of the whole of the water in the evaporator is advantageously withdrawn from the liquid in the evaporator. The evaporator liquid is then advantageously continuously passed into a decomposition plant and kept at a temperature of conveniently from 160‹ to 250‹ C. The vapour/gas mixture (of water, phthalimide, phthalic anhydride and ammonia) formed in the decomposition is returned to the phthalimide manufacture conveniently to the central region of the said countercurrent column. In a further preferred embodiment the concentrated evaporator liquid withdrawn continuously from the evaporator is not passed into the decomposer but direct into the countercurrent column of the phthalimide manufacture so that the decomposition is carried out in the reactor itself.

Title: New tropine derivatives and process for their manufacture
Filed: 1958-09-17
Abstract: The invention comprises scopine ethers of the general formula <FORM:0897729/IV (b)/1> (wherein R1 represents a C1-6 alkyl group and R2 a hydrogen or chlorine atom) and their acid addition salts, and the preparation of the basic ethers by reacting a diphenylmethane compound of the general formula <FORM:0897729/IV (b)/2> (wherein X represents hydrogen and Y chlorine or bromine, or XY represents the diazo residue, N2) with an epoxidized N-alkylnortropine compound of the general formula <FORM:0897729/IV (b)/3> or by reacting compound II with a tropine derivative of the general formula <FORM:0897729/IV (b)/4> (wherein A represents hydrogen or an acyl radical capable of being split off), splitting of the acyl group if present, esterifying the product with a sulphonic acid chloride Z-SO2Cl (wherein Z represents an aliphatic, aromatic or alkylaromatic radical) to form a compound of the general formula <FORM:0897729/IV (b)/5> which is then treated with an organic base to split off ZSO2OH with formation of a 6 : 7-double bond which is then epoxidized with trifluoroperacetic acid.  The acyl group A may be, for example, an acetyl group, which may be split off by warming with ethanolic caustic soda, or a phenylcarbamoyl group, which may be split off by simply heating in a high vacuum.  When A is hydrogen some 6-benzhydryl ether is formed in addition to the 3-benzhydryl ether and must be separated before the next stage of the process.  6b -Hydroxy- and -acyloxy-tropines of general formula IV are prepared by condensing hydroxysuccinic dialdehyde with acetonedicarboxylic acid and a primary alkylamine in the presence of a buffer material, reducing the resulting 6b -hydroxytropinone, and, if desired, acylating the 6b -hydroxy group before or after the reduction step.  Specification 708,911 is referred to.
