Title: Process for working up the wash solution obtained in the washing of  so2-containing off-gas using aqueous ammonia
IPC: B01D53/50
Filed: 1972-03-29
Abstract: 1376404 Sulphuric acid, sulphur dioxide CHEMIEBAU DR A ZIEREN GmbH & CO KG 29 March 1972 [31 Aug 1971] 14711/72 Heading C1A The sulphur content of a wash solution obtained by scrubbing SO 2  containing gases with aqueous ammonia is obtained and the nitrogen content of the solution rendered ecologically innocuous by mixing the wash solution, which contains ammonium sulphite, bisulphite, and optionally sulphate if the gas scrubbed contained SO 3 , with a quantity of sulphuric acid at least sufficient to liberate all the SO 2  from the sulphite and bisulphite content of the wash solution, and the resulting ammonium sulphate containing liquor is evaporated by direct heat-exchange with hot split gas, obtained as hereinafter explained, to a water content of from 15 to 55% by weight, and the concentrated mixture so obtained is heated at a temperature of 900‹ to 1250‹ C. with the simultaneous combustion of a carbon and/or sulphur containing fuel to form an SO 2  containing split gas which hot split gas is used for the evaporation and thereafter its SO 2  content is converted to sulphuric acid using the contact process. After being used for the evaporation the hot split gas may be washed before being subjected to the contact process and the wash solution to be treated by the process of invention is mixed with the H 2 SO 4 -containing wash acid from washing the split-gas to liberate its SO 2  content. Alternatively, a portion of the product acid from the contact process may be used to acidify the ammoniacal wash liquors being treated, to liberate their SO 2  content. The wash solution being treated and the acidifying sulphuric acid may be sprayed into a tower through which the hot split-gas flows upwardly. The SO 2  liberated from the ammonium salt content of the used wash liquor being acidified may be separated from the accompanying aqueous solutions and added to the split gas after it has been used for evaporation. The water content of the ammonium sulphate containing liquor may be reduced to 25 to 50 wt. per cent in the evaporating step. The concentrated liquor may be split at a temperature of 1000‹ to 1100‹C. using a residence time of 0À3 to 15 sees. in the splitting chamber. The splitting step may be carried out so that the oxygen content of the gases leaving the splitting chamber is from 2 to 10 vol. per cent. The SO 2  containing gas used for the present process may be tail-gas from a sulphuric acid plant or flue gas from the combustion of a sulphur containing fuel.

[Class 38 (iii)] Regenerative and non-regenerative braking.-A resistance for diverting a considerable proportion of the series field current of a motor during motoring, is removed from the field shunting connection during rheostatic braking, and is included in the braking circuit. In the first series position, armatures A1, A2 and series fields S1, S2, shunted by resistances hr1, hr2, are connected in series to the supply with resistances SR1, SR2, SR3, inserted. Shunt fields sh1, sh2 are also connected in series to the supply. In the next two series stages, resistances SR1, SR2, SR3, are cut out, and during four further series stages shunt field resistance r1-r5 is inserted in steps. At the first transition stage an additional armature series resistance SR4, is inserted, and the series field diverter circuits opened, and at a second transition stages the resistances SR1-SR3 are reinserted. At a third transition stage, contactors M2 and G are closed to connect the motor armature circuits in parallel with each other, and with the resistances SR1-SR3. At the first parallel stage contactor JR is opened to open the circuit of the resistances SR1-SR3, the series field diverter circuits reconnected, and shunt field resistances r4-r5 reinserted. At the second parallel stage the series resistance SR4 and shunt field resistances r4, r5 are again cut out. In four further parallel stages, shunt field resistances r2-r5 are inserted in steps. Backward movement of the controller gives regenerative braking both for parallel and series positions. For rheostatic braking bridging contacts BC1, BC2 are opened, and bridging contacts BC4, BC5 closed. The motor armatures are connected across their respective series fields and resistances hr1, hr2, in series, the resistances SR1, SR2 and a brake coil MB being also connected in the series circuits, and common to both. In the second rheostatic braking stage contactor R4 is closed to cut out resistance SR1. In four further rheostatic braking stages resistance SR2 is cut out, resistances SR2, SR3 are connected in parallel, resistances SR1, SR2, SR3 are connected in parallel, and all resistances SR1, SR2, SR3 are cut out. In an " off " position of the controller, the motors are disconnected from the supply, and the armature A1 is short-circuited with the series field diverter circuit opened. The series fields are strongly excited during rheostatic braking to enable braking even if shunt field supply should fail, a selected one of the motors may be removed from circuit.

Title: Improvements in or relating to extreme pressure grease
Filed: 1951-06-22
Abstract: An extreme pressure grease consists of a lubricating oil thickened with an alkali or alkaline earth metal soap of a sulphurized or sulphurized-phosphorized "fatty material."  The term "fatty material" includes materials containing a substantial proportion of oils containing fatty acids, e.g. tall oil.  The sulphurized or sulphurized-phosphorized fatty material is mixed with an equal amount of lubricating, oil heated, the desired metal solution, usually a hydroxide, added, and the temperature raised to dehydrate.  The remainder of the oil is then added, the batch heated till fluid, and then cooled and worked. Sulphurized or phosphorized-sulphurized sperm oil, sulphurized lard, animal fat or tall oils, sulphur monochloride-treated fatty oils, and phosphorus sulphide treated sulphurized fatty oils may be used.  A sulphur content of 2-20 per cent. with or without a phosphorus content of 0.1-0.5 per cent. is generally suitable. The soap content may be 10-50, preferably 15-30 per cent.  A mineral lubricating oil and/or synthetics such as long chain esters, e.g. sebacates and adipates, polymerized cracked wax, and alkylated aromatics may be used.  Examples are given of greases having the percentage composition: mineral oil 78.3 sulphurized or phosphorized sperm oil, sulphurized tall oil or sulphur monochloride-treated lard oil 20, and sodium hydroxide or lithium hydroxide monohydrate 1.7.  The use of a mixture of solvent extracted mineral oil and di-2-ethyl-hexyl sebacate is also illustrated. Sulphurized oils are prepared by heating sperm oil with molten sulphur at 300 DEG F. or more and then, if desired, with phosphorus sulphide at 215 DEG F. or by heating lard oil and S2Cl2 at 300 DEG F.

Abstract: 662,487. Electric welding. THOMSON ELECTRIC WELDER CO. June 7, 1949 [June 10, 1948], No. 15197/49. Class 83 (iv). [Also in Group XXIX] In a flash-butt-welding machine the moving electrode is advanced by fluid-pressure means, this movement being regulated by a dashpot connected to the electrode through a toggle so that its retarding effect is reduced to zero as the electrode completes its advance. This may be effected by a piston 18 in a fixed cylinder 16 and the piston-rod be connected to the electrode B through a lost-motion device 10 and to a crank lever 37 pivoted on a fixed axis 39. The other arm 38 of this lever forms one part of a toggle 38, 40 connected to the piston-rod 42 of a dashpot 44 which has its ends 47, 48 connected by piping and an adjustable metering valve 50 and a non-return valve 51 arranged to allow the oil in the space 48 to flow freely to 47, thus the piston 45 has no retarding effect on the advancing electrode B when the toggle has passed its dead centre. Then an arm 62 adjustably fixed to the lever 37 strikes a microswitch 61 to cut off the current. The advance of the electrode is limited by an adjustable stop 31 and its return by a stop 34. Rapid return of the electrode is effected by reversing the valve 20 and opening a valve 53. This is closed before the cycle is repeated. Scales 70, 71 and 72 may be provided to facilitate the adjustments. The device 10 prevents initial jerk of the electrode when the valve 20 is turned to advance it.

Abstract: 1537272 Soldering SCIENCE RESEARCH COUNCIL 2 April 1976 [14 April 1975] 15250/75 Heading B3R [Also in Division H1] A flat tape cable (1) (Fig. 1, not shown) comprises a flexible plastics base (3), e.g. polyester to which conductors (2), e.g. beryllium copper are affixed by polyurethane varnish (4) which at room temperature acts as an insulator and an application of heat serves as a flux to enable solder connections to be made to the cable without the need for additional flux. The varnish (4) need not completely surround the conductors (Fig. 2, not shown). The conductors may be sandwiched between two sheets. In connecting the cable to, e.g. a circuit board 29, Fig. 4, having a row of pre-tinned terminals 28 with the same pitch as the cable conductors, cable 1 is laid over the terminals and heat is applied from the back of the cable by a soldering iron 30 having a wide bit 31, which melts the plastics backing and solders the wires to the terminals. In an apparatus for manufacurring the cable (Fig. 3, not shown) a sheet of the plastics used for the backing is wrapped around a drum and one or more conductors are passed through a bath of polyurethane varnish and wound helically on the drum. The plastics sheet may then be slit as required to obtain the tape cable.
