Title: A process for the manufacture of the dimethyl esters of terephthalic and isophthalic acid
IPC: C07C69/80
Filed: 1959-10-19
Abstract: In a process for the manufacture of dimethyl terephthalate and/or isophthalate by esterification of the appropriate acid(s) with excess methanol, the reaction-product is passed to a distillation column where it is fractionated under such conditions of temperature and pressure that methanol is withdrawn from the head of the column, and liquid ester and liquid water are withdrawn, separately or together, from the lower section of the column.  The temperature in the lower part of the column should be higher than 140 DEG C., and the pressure should exceed 3.6 atm.  If the ester and water are drawn off together, they are separated in a phase-separator maintained at a temperature higher than the melting-point of the ester and at a pressure higher than the vapour-pressure of water, corresponding to the temperature.  The methanol obtained at the head of the column may contain less than 1% by weight of water, and is returned to the esterification reactor.  In an example, a solution of terephthalic acid in an excess of methanol is passed at 250 DEG C. and a pressure of 85 atm. gauge through a tubular reactor divided by partitions into 10 compartments connected in series.  The mixture leaves the tenth compartment after a residence time of two hours, and is introduced into a distillation column in which the pressure is 4 atm. absolute. Liquid ester is withdrawn from the bottom of the column at a temperature of 155 DEG C.  Water is removed some distance above the bottom, and methanol is withdrawn from the top of the column. Dimethyl terephthalate is distilled off in vacuo from the liquid ester, until approximately equimolar quantities of dimethyl terephthalate and monomethyl terephthalate remain behind as residue. This residue is returned to the tubular reactor.  The dimethyl terephthalate, obtained as distillate, may be purified by crystallization from methanol; and the mother-liquor may be passed to the reactor.ALSO:In a process for the manufacture of dimethyl terephthalate and/or isophthalate by esterification of the appropriate acid(s) with excess methanol, the reaction product is passed to a distillation column where it is fractionated under such conditions of temperature and pressure that methanol is withdrawn from the head of the column and liquid ester and liquid water are withdrawn, separately or together, from the lower section of the column.

Title: Improvements relating to the manufacture of bread, rolls and the like baked products
IPC: A21D2/02
Filed: 1934-12-17
Abstract: The crust colour of baked goods is improved by contacting the surface of the dough ammonia or an ammonium compound which rapidly decomposes under heat treatment.  The process is used, preferably, when a sugar, other than cane sugar, is incorporated in the dough batch.  The ammonium compounds suitable for use are, ammonium hydroxide, ammonium tartrate, ammonium carbonates including the normal, bi, sesqui and the carbonate-carbamate, ammonium malonate.  The ammonia or compound may be applied to the dough by a sponge, cloth or brush, or by spraying or dipping, or it may be introduced into the oven with the steam either through a separate inlet or through an inlet common to the steam and the material.  A solution of ammonium hydroxide of strength 0,1N applied with a brush, and a spraying with a solution of ammonium bicarbonate of strength 0,3N are particularly referred to. Alternately, gaseous ammonia from a cylinder is added to the steam, or the steam may be caused to pass through a solution of ammonia or a solution of ammonia or an ammonium compound may be added to the steam immediately prior to its entry into the oven.

Title: Improvements in or relating to apparatus for controlling a washing or like cleaning machine
Inventor: WEIR HENRY JOHN
IPC: D06F39/02
Filed: 1956-11-27
Abstract: 865,274. Washing &c. machines. WEIR ECONOMATICS Ltd. Nov. 18, 1957 [Nov. 27, 1956; March 14, 1957; Sept. 6, 1957], Nos. 36273/56, 8490/57 and 28218/57. Class 138 (2). Apparatus for the control of washing- or like cleaning-machines comprises a plurality of interchangeable rotatable programme timing cylinders which are rotated in a series of steps, the length of which is determined by a characteristic of the cylinder so that one complete rotation corresponds to the control of a complete working cycle. The washing-machine controller is arranged to be able to supply liquid, steam, and pulverulent material to a washing-machine. Sprocket wheel 28 is driven by chain 17 and drives shaft 27 on which is a cam 26 the rotation of which rocks lever 29 and by means of unidirectional ball and slope clutches A and B arranged so that the positive movement of lever 29 drives gears 38 and 24 while they are prevented from rotating on its return movement. The return movement of lever 29 is limited by the engagement of a roller on arm 39 with a stepped recess 19 on the timing cylinder 18 so that said recess effectively controls the length of the stroke of lever 29, the angle of rotation per step of gears 38 and 24, and thus the time taken for a complete rotation of cylinder 18. When a non-cleaning operation is being performed the rotation of cylinder 18 is stopped by the de-energization of solenoid 40 and release of trip lever 41 to engage arm 34 and prevent the return stroke of lever 29. Motor 7 also drives continuously two clutches 9 and 11 which control the supply of water or steam and another two clutches 12 and 13 which control the addition of powdered soap or alkali from the hoppers 70. These continuouslydriven clutches only transfer their drive to the controlled units when replaced by solenoids 53, 55 or 59 acting through rods 50 and 58. Clutches 9 and 11 are only required to rotate through 180 degrees to turn the valves on, whereas clutches 12 and 13 transfer their drives throughout the period when solid additions are required. A water level sensitive element 64 is used to allow the main timing cam drive to be interrupted while the machine is filling and emptying so that variations in water pressure, slight drain blockage &c. will not affect the time of the operative washing or rinsing operations. Specification 865,275 is referred to.

Class 107 A road-sweeper comprises a self-contained vehicle having a rotary sweeping brush throwing sweepings into a collecting container on the vehicle, and vacuum means sucking air through the brush and through a filter in which the finer dust is trapped. The brush 6 works in a closed chamber having depending valances 22 of resilient material around its lower opening, and sweeps rubbish into a detachable or liftable container 9. Air is drawn through the brush, filter 18 and a flexible hose 19 by a fan 20. Some or all the air discharged from the fan is directed on to the ground at the side of the brush to blow dust to the transverse centre of the brush to avoid leaving a trail. A conventional gutter brush 50 may be fitted and the drive to the fan brushes and road wheels is taken from a gear box 39, which may be arranged to drive the brushes at constant speed. The vehicle is steered by a bar 4 on a single front wheel 3. To empty the sweepings, the container 9 may be elevated (as shown in chain lines) by a link 11 operated by a screwed rod 15 under control of a hand-wheel 17.
