Patent GB-606442-A (GB)
Title: Improvements in or relating to the manufacture of complex granulated fertilisers
IPC: C05B19/02
Filed: 1945-10-18
Abstract: A complex fertilizer is produced from an initial mixture of fertilizer substances including mono-calcium-phosphate containing free acid by reason of its production by the action of an acid on raw phosphate, by adding one or more neutralizing agents to neutralize the free acid prior to the addition of a hot ammonium nitrate solution and subsequent granulation by agitation and cooling. Neutralization may be effected by a base e.g. lime or ammonia, one or more salts having an alkaline reaction e.g. calcium carbonate or calcium carbonate and calcium phosphate, or other substances having an alkaline reaction e.g. basic slag.  The initial mixture with the neutralizing agent incorporated therein may be heated to 50 DEG -100 DEG C. before adding the ammonium nitrate in the form of a 80-85 per cent solution.  In a modification where neutralisation is slow, the ammonium nitrate equal at least to 25 per cent by weight of the initial mixture may be added before the end of the neutralization reaction.  Examples given include the treatment of mixtures of potassium chloride and solubilized tricalcium phosphate and potassium chloride, superphosphate and Morroccan phosphate.

A method of manufacturing elastic textile fabrics comprises stitch-bonding a non-woven fibrous web of substantially transverse fibre orientation by using an atlas laying, crimping the fabric by exposing it to the action of a swelling agent e.g. sodium hydroxide, or by a thermoplasticising treatment, while simultaneously tensioning it either in the longitudinal or in the transverse direction, and finally fixing the crimped fabric. As a swelling agent there may be used water or solutions of zinc chloride, urea, thiourea, pyridine, phosphoric acid, acetic acid, cresol or formic acid. The crimp may be stabilised by impregnation with a solution of cycloethyleneurea and dimethylol-urea or by cooling while under tension.

Abstract: 276,578. Porter, O. W. L. March 14, 1927. Grates.-An adjustable front grate comprises a lower grid 1 and an upper grid 5 hinged to it, the lower grid being pivoted at or near its lower edge to the side checks 2 so that it may be moved back from an inclined to a vertical position, whilst the upper grid may be adjusted, in either position of the lower grid, to a vertical or a forwardly-projecting horizontal position. In the construction shown, the pivot pins 3 of the lower grid engage vertical slots 4 in the side cheeky and the pivot pins 6 connecting the upper grid to it engage arcuate slots 7. In the position shown in Fig. 1, the upper grid is maintained horizontal by the engagement of lugs 8 on its underside with lugs 9 on the side cheeks or a front rail 10 which connects them. To adjust the upper grid to the vertical position, it is raised until side lugs 11 on it can be passed over projections 12 on the cheeks, being then maintained in position between the projections 12, 13. Fig. 3 shows the lower grid 1 in the vertical position, in which it is retained by the engagement of the pivot pins 6 in a depression 14 at the end of the slot 7. The upper grid is held horizontally by the lug 8, which abuts against a lug 15 on the lower grid. In the vertical position the upper grid is held between projections on the side cheeks.

In a method of flock printing wallpaper an adhesive is applied to the areas to be flocked by a suitably engraved roller 6 and the web Z is then passed through a flocking machine 11 where the flock is beaten by rotary beaters 18, 19, 20 on a foraminous screen to fall evenly therethrough on to the wallpaper such that the applied adhesive becomes loaded with flock. The surplus flock is then removed from the web by an air system comprising nozzles 30, 34, fan 31 and collecting bag 33 which blows the loose flock to a region beneath a suction hood from which it is passed to the bag 33. The web is next moved through a drying oven 12 being finally batched, reeled and/or cut by a suitable device 37. The engraved roller 6 is associated with an impression cylinder 4, a trough 9a and an adhesive heater H. As the wallpaper passes through the flocking machine it is vibrated in order to even out the layer of flock settling thereon.
