Title: Improvements in and relating to the production of mixed fertilisers
IPC: C05B11/06
Filed: 1929-05-18
Abstract: 312,169. Jost, F. May 21, 1928, [Convention date]. Addition to 306,046. Manures.-the treatment of calcium phosphate with nitric acid and of the solution so obtained with alkali chloride described in the parent Specification is modified to obtain mixed fertilizers by distilling a mixture of the phosphate, an alkali chloride or chlorides, and nitric acid. Vapours of hydrochloric and nitric acid evolved are absorbed in alkali, for instance by ammonia, milk of lime. or soda lye, to produce a strewable non- hygroscopic fertilizer. The residue consists mainly of alkali nitrate and calcium phosphate, with a little sodium chloride, which' forms a valuable mixed fertilizer. If the distillation is interrupted so that an acid residue is obtained, this may be neutralized with ammonia. Distillation may be effected under reduced pressure; or in a current of air to prevent loss of nitric acid ; and tri-calcium phosphate separating out during the distillation may be separately removed. The process may be interrupted before distillation is complete, the solid residues being used in a fresh distillation. Excess of sodium chloride and calcium phosphate with respect to the nitric acid may be used.

Patent GB-424744-A (GB)
Title: Improvements in or relating to rubber threads and methods of making the same
IPC: B29D99/00
Filed: 1934-05-25
Abstract: A rubber thread consists of a number of parallel strands bonded together, the bond being such that under normal conditions the thread acts as an integral structure, without destroying the identity of each strand.  Relative displacement is thus avoided, and tension is equally distributed, while breakage of any of the strands, does not affect the remainder.  The thread may be made by lightly cementing together two sheets of rubber, and cutting threads from the laminated sheet, or filaments of suitable cross-section, e.g. semicircular, may be extruded, and passed through grooved rolls to press their flat faces together, the degree of adhesion being controlled by the application to these faces of more or less of a finely divided material such as talc. Preferably the faces in contact are as broad as possible. Rubbers having different properties or colours can be thus combined, and the thread may be braided, wrapped, &c. as usual.

Filed: 1956-05-18
Abstract: 798,345. Automatic bobbin-changing looms. FISCHER AKT.-GES., G. May 18, 1956, No. 15637/56. Class 142(2) In a loom having two shuttles picked simultaneously through superposed sheds, automatic bobbin-changing is effected by moving the shuttle box containing the depleted shuttle forwardly to bring it under the magazine at front dead centre, thereby enabling a fresh bobbin inserted by a hammer 21 to eject the spent bobbin through the bottom of the box. When a depleted upper shuttle is detected at the other end of the loom, an electromagnet 42 is energized to lift a latch 14 clear of the nose 11N of a floating lever 11, allowing it to swing to the right under the action of a spring 33 so that a notch in its rear edge engages a pin 13 on an arm 31; also, a link 27 swings a floating arm 26 to engage a notch in its rear edge with a pin 41 on an arm 28; in addition, the nose 11N displaces a lever 16 which acts through linkage 18, 19 to lift a hammer-operating dog 20 into the path of the slay. Cams 29, 30 on the crankshaft depress the arms 28, 31, the former acting through connections 41, 26. 25 on a parallel linkage 24 carrying the magazine 22, whereby the magazine is raised to the position shown; the arm 31 acts through connections 13, 10, 7, 5, 3 to slide the upper shuttle box 1 forward, so that it registers with the magazine at beat-up. The parts return to their normal positions when a pin 38 on the crankshaft pushes the floating lever 11 off the pin 13. The mechanism is duplicated to move the lower shuttle box 2 except that, in this case, there is no link from the floating lever 12 to the floating arm 26 as the magazine does not require to be raised.
