Abstract: 1,000,417. Concentration of aqueous formaldehyde by distillation. CELANESE CORPORATION OF AMERICA. Nov. 15, 1961 [Nov. 15, 1960 (3)], No. 40845/61. Heading BIB. Aqueous formaldehyde is concentrated by distilling it under an absolute pressure of at least 37 lbs./sq. inch in a fractionating column and adding acetone to the top section of the column at such a rate that the ratio of water to acetone in the vapours removed from the top of the column is 10-20 times the ratio of water to acetone in the azeotropic mixture corresponding to the pressure under which the column is operated. A crude mixture of formaldehyde, water and methanol is fed via line 11 to a preliminary distillation column 12 operated at atmospheric pressure. Methanol and other light impurities are removed overhead, and the bottoms fraction, comprising mainly formaldehyde and water, is passed into column 16, which is maintained under a gauge pressure of 40 1bs./sq. inch. The top section of column 16 is supplied with a liquid mixture of acetone, formaldehyde and water at 4.5 times the rate of feed to the column ; and the vapour mixture removed from the top of the column is passed into condenser 17 wherein it is partially condensed, yielding a condensate which is returned to column 16 as reflux, and a vapour mixture, rich in acetone and formaldehyde, which is passed via pressure-reducing valve 27 into column 18 maintained at, or just above, atmospheric pressure. The vapour mixture leaving the top of column 18 passes into condenser 19, wherein the major part of it is condensed ; the condensate is divided into two parts, one part being refluxed to column 18, and the remainder being supplied to the top section of column 16. The uncondensed vapour mixture, which is rich in formaldehyde, passes into a scrubbing tower 21, which is supplied with a controlled proportion of water via line 28. The aqueous solution withdrawn from tower 21 is passed into a fractionating column 22, from which a vapour side stream of concentrated purified aqueous formaldehyde is taken off just above the base of the column via line 25. The vapours leaving the top of column 22 are principally acetone vapours, and are condensed in condenser 23, the condensate being supplied to the top section of column 16. A bleed of concentrated aqueous formaldehyde is withdrawn from the base of column 22 and is blended with the feed to column 16. The residue from the base of column 16, containing mainly water and a trace of formaldehyde, is discharged as effluent. The liquid residue from the base of column 18, comprising dilute aqueous formaldehyde plus traces of methanol and coloured impurities, may be blended with the feed to column 16 or rejected from the system. A liquid side stream drawn off from column 18 via line 24 contains unwanted colour impurities, and is either rejected or recycled to the feed to column 12. The feed to column 12 may be a mixture obtained by the partial oxidation of propane and/or butane.

In a straight-bar or flat knitting machine, a hooked take-up bar is engageable with loops of an initial course of each successive work piece produced, the bar being intermittently moved between knitting traverses linearly away from the needles or sinkers to apply tension to the work which is later drawn off by a pair of rollers, the work being disengaged from the hooks, at least one of the rollers being driven intermittently in time with the movements of the bar. Between fixed frame needles 3 are frame needles 3' carried in a vertically displaceable bar beneath component 7 of frame needle bar 2 so as to be slidable into inoperative positions for rib knitting leaving spaces S in which the machine needles 9 operate. Needles 9 have inner elements with operating butts 9a controlled by a cam-operated actuating bar 10. Sinkers 6 in sinker bed 5 sink the loops round the frame needles. For each division of the machine is provided a take-up bar 12 with hooks 13 engageable with the loops il of the initial course of a piece of work and actuated by initial racking means and then further racking means both driven by one motor to draw the work off until it is taken by roller 15 which is racked in time with the movements of bar 12, the work piece being finally deposited in a receptacle 16. Secured by pins 22 to the ends of bar 12 are cam pieces 23 connected by links biassed by springs 20 to housings 19 mounted on endless chains 18 carried on sprockets including driven sprockets 24 which are rotated clockwise or anticlockwise. The springs 20 across the divisions of the machine take up local irregularities in the length of fabric formed. Pins 25 on cam pieces 23 engage tracks 26 to hold bar 12 horizontal until it passes beyond rollers 14, 15 when the tracks 26 are cut away so that the bar 12 drops to carry the fabric between rollers 14, 15 and to disengage the hooks 13. Roller 14 is temporarily raised to allow bar 12 to pass the rollers 14, 15 which are then rotated intermittently between carrier traverses by the action of cams 29. When required, the bar 12 is returned to its starting position by electric motor 31 and the top surfaces of cam guides 29 engage pins 25 to ensure that   it returns with the hooks horizontal and correctly aligned, the guides 29 blocking gaps 27. A tuning drum indirectly coupled with shaft 33 which carries sprocket 24 has plates 112 which, at intervals, receive the rollers 113 of micro switches 114 to control the functions of bar 12. The motor drives shaft 33 through one clutch or preferably two clutches so that the transmission is balanced. Shaft 33 is driven clockwise by rackwheel 47 and pawl 48 and anti-clockwise through rack wheel 35 and pawl 36 as seen in Fig. 8. Shaft 33 drives all but three of the bars 12 on the machine and these are driven by shaft (133) and this is arranged so that, in the event of excessive tension being applied to the fabric, a switch (134) will be operated to disconnect the drive see Fig. 10 (not shown).
