Abstract: 384,177. Welding; pipe-end closing. SUPERHEATER CO., Ltd., Bush House, Aldwych, London.-(Compagnie des Surchaffeurs Soc. Anon. ; 3, Rue la B÷etie, Paris.) April 30, 1932, No. 12484. [Class 83 (iv).] The ends of two tubes 1, 2 disposed one within the other are jointed by heating the tube ends and then welding them together preferably by means of an anvil 4 and a pair of swages or dies 5. The inner tube is forced against the anvil, which may be rotatable or stationary whereupon the end thereof is expanded, and at the same time the swages, which are reciprocated radially of and also revolve about the tube end 1, are set in operation and serve first to contract the tube end 1 into contact with the tube 2 and then to effect the welding operation. Fig. 7 shows the finished joint after the removal of the annular rib 7 formed during the forging operation. The welding may be effected by pressure instead of by hammering, and only one of the tube ends need be expanded or contracted. The end of one or both tubes may be thickened, as shown for example in Fig. 11, prior to forging.

Title: Automatic anti-lock control system for a vehicle with a trailer
IPC: B60T8/17
Filed: 1973-03-15
Abstract: 1414341 Anti-skid brake control systems TELDIX GmbH 15 March 1973 [16 March 1972] 12603/73 Heading F2F An anti-skid brake control system for a vehicle with a trailer comprises means for producing a signal corresponding to the vehicle speed, a comparator element for comparing this signal or a signal dependent thereon with a signal corresponding to the speed of at least one trailer wheel, the comparator output signal passing to a modifying element to produce a signal to control the trailer brakes in accordance with the trailer wheel speed. A unit 7 accepts signals from wheel speed sensors 4 for vehicle front wheels 1a, 1b, with, possibly, deceleration sensors, these signals being delayed in store units 6. The output from the unit 7 is fed to comparators 8a, 8b, 9a, 9b which each compare the signal with signals corresponding to the speed of each wheel la, 1b, 2a, 2b, the outputs controlling brakes 5 for the wheels. The output from unit 7 also passes to a comparator 11 which also accepts a signal from a unit 12 which compares individual trailer wheel speed signals and chooses the higher value. The comparator output passes to a resistor-capacitor unit 13 to damp out residual fluctuations and then to control a variable resistance unit 10 also fed by a direct signal from the unit 7 in an open loop control. The resistance unit output is fed to comparators for the trailer wheels similar to those 8a-9b for the vehicle wheels. The variable resistance unit comprises a transistor controlled by the comparator 11 in series with a fixed resistance, the unit output being tapped off between the transistor and resistance. A closed loop control may be added, comprising a feedback to the unit 13 from a comparator having inputs from the resistance unit 10 and the trailer wheel speed comparator 12. Alternatively, the resistance unit is replaced by a variable amplifier accepting the signal from the unit 7 and feeding the comparator 11, the amplifier being controlled by the output from the unit 13.

Title: Method of production of sulphuric acid
IPC: C01B17/60
Filed: 1951-05-30
Abstract: A mixture of sulphur dioxide, sulphur trioxide, sulphuric acid and water vapours, produced say, by decomposition of basic iron sulphate in a stream of hot sulphurous gases, or by subjecting sulphur dioxide from pyrites roasting, after dry dust removal, to partial catalytic oxidation, at a temperature above the dew point of the sulphuric acid (say at above 400 DEG C), is <PICT:0694912/III/1> brought into contact in counterflow in a single condenser with concentrated not less than 94 per cent sulphuric acid at below 100 DEG C whereby the sulphuric acid and water vapours are condensed and the sulphur trioxide is absorbed.  The gas mixture is passed at 12 into packed tower 2 while 98 per cent sulphuric acid is sprayed through holes 13. Sulphuric acid is withdrawn from the tower through cooler 5 to tank 4 and part goes to produce at f, part is recycled by pump 3 to acid sprays 13, and part is added through 6 to the hot acid in the base of the tower to keep its temperature below 100 DEG C.  Sulphurous gases are sucked from tower 2 at 16 by high speed blower 7 which effects centrifuging to remove any acid mist.  The gases then pass to tower 8 against dilute sulphuric acid mists from atomizer 9, and are withdrawn at f6 and may be worked up to sulphuric acid.

Patent GB-695636-A (GB)
Title: Improvements in or relating to process of purifying acrylonitrile
Filed: 1950-05-24
Abstract: An aqueous solution of acrylonitrile containing volatile impurities is purified by contacting the aqueous solution with a stream of acetylene to strip the volatile impurities therefrom and to obtain a water solution of acrylonitrile substantially free from volatile impurities.  The process is of particular utility in the case of acrylonitrile solutions resulting from the reaction of acetylene and hydrogen cyanide in the presence <PICT:0695636/IV (b)/1> of cuprous chloride, the volatile impurities comprising chlorobutadiene, monovinyl acetylene and divinyl acetylene.  The acrylonitrile solution freed from volatile impurities may be subjected to steam stripping for recovery of the acrylonitrile whilst the gas fraction consisting of acetylene and the volatile impurities may be passed into an oil absorber where the oil soluble impurities are preferentially absorbed in a suitable oil such as wash oil or other nonreactive aliphatic or aromatic solvent, e.g. a refined hydrocarbon or mineral oil, although mono- and polyaric alcohols such as glycerine and glycol, as well as esters such as dibutyl phthalate may also be used.  The acetylene which passes on may be re-used in the acrylonitrile synthesis.  The purification process may be carried out at atmospheric or superatmospheric pressure.  In the drawing, acetylene and hydrogen cyanide are passed into the reactor 10 containing a hydrochloric acid solution of cuprous chloride and the reaction products comprising acrylonitrile, unreacted acetylene and hydrogen cyanide, together with small amounts if acetaldehyde, chlorobutadiene, monovinyl acetylene, divinyl acetylene, cyanobutadiene and lactonitrile are cooled by cooler 14 and then passed into the absorber 16 to which water is supplied by pipe 17. The acetylene being largely insoluble in water passes out by pipe 18 and enters oil scrubber 20 whilst the absorber 16 is fed with acetylene gas by pipe 21 in an amount sufficient to transfer to the gas phase the chlorobutadiene, monovinyl acetylene and divinyl acetylene and the acetylene thus introduced along with the excess acetylene introduced with the reaction product enters the oil scrubber 20 via pipes 18 and 19.  The oil in the scrubber dissolves out the impurities present in the acetylene and the scrubbed out impurities are passed to purifying means 23 from which the purified oil leaves by pipe 24.  The oil may be re-introduced to the oil scrubber by pipe 25 whilst the scrubbed acetylene is returned to the acetylene supply line by pipe 12A.  The recycled acetylene may be continuously or intermittently purged at 26.  The purified aqueous solution of acryonitrile passes from the absorber 16 to the stripper 28 where the arylonitrile is boiled out of the solution and then passes to condenser 33 where it is liquefied.  The liquefied product which contains water is passed to separator 34 and the upper layer which consists of acrylonitrile containing a little water is then withdrawn and may be dehydrated whilst the lower water layer is returned to the stripper 28.
