Title: The manufacture of new derivatives of higher fatty acids containing sulphur
IPC: C11C3/00
Filed: 1929-09-11
Abstract: Higher fatty acid derivatives containing sulphur are prepared by treating with solutions of sulphides or polysulphides polyhalogenated fatty acids containing more than 8 carbon atoms in the molecule or their esters or amides or conversion products still containing halogen obtained according to Specifications 339,675, [Class 2 (iii), Dyes &c.], and 340,011, by treating polyhalogenated higher fatty acids with alkaline acting reagents or solutions of ammonia in organic solvents.  The halogens are in part replaced by mercapto and hydroxy groups, and in part split off with the formation of double bonds.  The reaction may be effected under pressure, and the products yield salts on being salted out, which are typical sulphonated soaps. In examples, (1) trichlorpalmitic acid, hexachlororicinoleic acid and heptachlorstearic acid (all prepared from the parent acids and chlorine as described in Specification 336,623, [Class 2 (iii), Dyes &c.]), are treated with aqueous solutions of crystallized sodium sulphide: (2) hexachlorstearic acid is treated with an aqueous solution of sodium tetrasulphide, the chlorinated stearic acid being prepared from a solution of the parent acid in carbon tetrachloride and chlorine: (3) a tetrachloroleic acid, similarly prepared, is treated with aqueous potassium hydrosulphide: (4) oleicacid chloride is treated with ethylaniline to form oleic ethylanilide, and a hexachlorinated derivative thereof is prepared by treating its solution in an organic solvent with chlorine.  The hexachloroleicethylanilide is heated with alcoholic potassium hydrosulphide in an autoclave: (5) a conversion product obtained according to Specification 340,011 from a pentachlorstearic acid and caustic soda is heated with aqueous sodium sulphide.

Abstract: 480,191. Vehicle spring - suspensions. FISCHER, S. Oct. 17, 1936, No. 28281. Convention date, Oct. 19, 1935. [Class 108 (ii)] In vehicles having wheels independently suspended by links &c. wherein spiral springs are arranged preferably between links which are connected to the wheel-carrying links of two opposed wheels the wheel-carrying links or the like are sloped downwardly from the frame and make an angle of from 20 to 40 to the vertical while the spring links make an angle to the vertical such that the sum of the said two angles is more than 90. Fig. 1 shows an arrangement in which the wheels are carried by links 13, 16, 131, 161 from the brackets 11<1> of the vehicle frame 11 the links being disposed at an angle alpha, alpha<1> to the vertical and being provided with arms 19, 19<1> sloped to the vertical at an angle #, #<1> such that the sum of the angles alpha # is less than 90. The arms 19, 19<1> are interconnected by a tension spring 21. When the wheels move vertically in opposite senses the frame 11 tends to oscillate about its instantaneous axis M and since the spring becomes stretched owing to the difference in the projections of the points 20, 201 on the axis of the spring the latter tends to set up a restoring force acting through point m. In cornering as shown in Fig. 4, the restoring force of the spring is greater since the arms 19, 19<1> move in opposite directions and as the instantaneous axis M becomes lower in relation to the centre of gravity 0 and eventually, at speed, falls below it the spring masses tend to become righted until the moment of the centrifugal force balances the spring centring forces. When compression springs are employed the spring arms 19, 19<1> slope upwardly away from the central longitudinal plane and are usually connected to the lower links 16, 16<1>. Additional springs 27, Fig. 6, may be connected between arms secured to the links and the frame to alter the spring characteristic, the spring 27 being out of alignment with the spring arm 30. In this Figure driving means for the wheels are shown.

IPC: C01B21/46
Filed: 1964-07-09
Abstract: <PICT:1076025/C1/1> Purification of HNO3 by a rectification process is preceded by the removal of dissolved gases from the HNO3 by heating under less than atmospheric pressure at a temperature corresponding to the boiling point of HNO3 under the selected pressure.  The preferred pressure is 560 mm. Hg. and the temperature is 75-80 DEG  C. The rectification process may be a three-step process comprising vaporization, vapour scrubbing and condensation, each carried out in a separate apparatus. HNO3 from pressure tank 1 enters column 4, where dissolved inert gases and nitrogen oxides are removed, and then passes to evaporator 5, where it is vaporized. 20-80% of HNO3 fed to 5 is drained during vaporization.  Vapour flows to packed or platetype column 7, where entrained aerosol particles are removed, and then the vapour is scrubbed with a small amount of acid reflux (reflux ratio up to 10) flowing downwards from condenser 8 through reflux distributer 9 and returning to 5. HNO3 vapour is condensed in 8, cooled by the refrigeration system 10, and fed to reflux distributer 9 and then to dilution tank 13 for HNO3 of desired concentration.  The acid vapour purified in 4, and which remains uncondensed in 8, passes to absorber 11 where it is sprayed with distilled water from 2, yielding acid of standard purity in 12.  The equipment is made of materials resistant to corrosion by HNO3, e.g. glass, high-purity quartz or polytetrafluoroethylene.

Abstract: 281,237. Junkers, H. Nov. 29, 1926, [Convention date]. Yielding toothed wheels; universal joints.- Relates to torque-transmission couplings, particularly for connecting a reciprocating engine to a high-speed machine, of the kind in which a spring coupling is disposed concentrically and, in series with a friction coupling adapted to slip at a predetermined load. The engine shaft 1, Fig. 1, drives a shaft 3 through universal joints or the spring-pin coupling 2 shown, the shaft 3 carrying a disc 4 having radial recesses 5 normally aligned with recesses 9 in friction plates 7, 8. Tangenthat helical springs 6, bearing on the end walls of both sets of recesses, yield by compression to torque in either direction. The springs may close up solid on heavy load, when the plates 7, 8, pressed by springs 18 against the walls 10, 11 of a hollow toothed wheel 12, are caused to slip, and the drive through a pinion 20 to an air-compressor 22 ceases. The bearings 14, 15 for the wheel 12 are preferably plain, so that they damp spring oscillations. The universal coupling 2 may be dispensed with, and sufficient play allowed between the disc 4 and plates 7, 8, or, it is stated, may be disposed on the output side. Clutches, claw and friction.-The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the modification shown in Fig. 4 (cancelled), in which the driving-wheel 42 has a spring coupling noly. and drives through a pinion 43 on a shaft 50, connected through a multipleplate coupling 60, 61 to a wheel 82 meshing with a driven pinion 84. The end plate 67 thrusts on a bearing 68 and the end plate 66 has splined engagement 69, 70 with the shaft 50 and is pressed by a spring 73 abutting on a shaft collar 71. The wheel 82 is carried in bearings 80, 81. By screw-and-nut gear 90, 91 the shaft 50 can be moved to the left, first to slacken the spring 73 to interrupt drive to the wheel 82. then to uncouple a dog clutch 45, 46 between the shaft and a sleeve-extension 44 of the pinion 43, and finally to release the spring 103 of a cone clutch 100, 104 and so isolate the shaft 50. This subjectmatter does not appear in the Specification as accepted.
