Title: Improvements in or relating to the manufacture of wire nets
IPC: B21F27/10
Filed: 1957-04-01
Abstract: 848,645. Making wire nets; welding by pressure. SLAHLNETZ G.m.b.H. April 1, 1957 [Jan. 18, 1957], No. 10583/57. Classes 83 (2) and 83 (4). In a process for simultaneously making several wire nets, a transverse wire is successively applied to several intermittently moved webs of longitudinal wires and welded thereto, whereafter the transverse wire length just welded is severed from the previously welded transverse wire length of the adjacent web and the web is fed forward. In one machine for carrying out the invention, four sets or webs of longitudinal wires are fed from spools 28, Figs. 2 and 3,.pass between pairs of welding electrodes such as 6, 21 and 8, 23, where the transverse wires are attached and finally the finished nets are wound up on intermittently rotated reels 51. The four longitudinal-wire feeding components are arranged along the sides of a square and within the square is a vertical shaft 31 driven by a motor 32 and carrying three radial arms 36, 37, 38 having at their ends guide-pulleys 151, 152, 15<SP>3</SP> which flay the transverse wires from reels 40<SP>1</SP>, 40<SP>2</SP> and 40<SP>3</SP> across the longitudinal webs between the welding electrodes. Driven from a gear 43 on the shaft 31 are horizontal shafts 46 carrying eccentric discs 47 which drive the takeup reels 51 through pawls 48 and ratchet-wheels 49 and a friction drive (not shown). When a length of wire has been laid transversely across a web of longitudinal wires, the electrode associated with that web is actuated to effect the line of welds and a cutter 18 then severs the wire from that previously welded to the preceding web. Between the webs, at the corners of the square, the transverse wires pass round cylindrical stop-pins. Another form of machine, Figs. 4 and 5, also comprises four component machines arranged in the form of a square. In each compartment, longitudinal wires from spools 97 pass round guide-pulleys 98, 99, between the welding electrodes 56, 67, guidepulleys 91, 92, driven transport roll 90 and pulley 93 to the take-up reel 81. The reels 81 are intermittently rotated from motors 78, 79 through clutches 76, 77, eccentric discs 86, 87, pawls 85 and ratchet-wheels 82. Rolls 90 are similarly driven by pawls 88 and ratchetmechanism 89. The movable electrodes such as 67 are actuated through levers 71 rocked from the clutches 77. Three spools 107 for the transverse wire are mounted on a circular carrier 103 mounted on rollers and driven by a belt 108. Feelers 115-118 are arranged one at each corner of the square and are included in circuits acting on the clutches 76, 77 so that a component machine is operated when a transverse wire under feed-tension is in contact with a feeler.

Abstract: 161,578. Soc. Anon. per la Fotografia Autopancromatica. April 12, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Printing-processes; printing in several colours. -To ensure correct register of a plurality of single colour partial pictures for the purpose of making a multi-coloured picture on paper, expansion or contraction of the picture receiving paper is prevented by sticking it on a non-extensible support, such as metal, glass, celluloid, &c. before the partial pictures are applied, the paper being removed from the support when the multicoloured picture is complete. The adhesive may be applied to the support and the paper then stuck on, or it may be applied to the back of the paper, in which case it is dried off and moistened just before sticking on the support in order to prevent creasing. To avoid the soaking necessary to remove the finished picture from the support, which might cause damage to the picture, the surface of the glass, metal, &c. support may be coated before applying the paper with talc, collodion, celluloid, wax, indiarubber, oxgall, &c. to diminish the adhesion of the adhesive thereto, so that the paper may be readily drawn off when the adhesive is dry, or a non- drying adhesive may be used. The pictures may be produced by printing off, by absorption, by transfer, or photo-mechanically.

Title: Improvements in or relating to the manufacture or production of material suitable for use as fertilizing material
IPC: C05B7/00
Filed: 1921-04-15
Abstract: Gases containing ammonia are caused to react with the semi-dry product obtained by treating with acid a naturally-occurring material that contains a secondary fertilizing agent or agents, such as a salt of potassium or a phosphate, but which is free, or almost free, from lime and is not generally regarded as a manure in itself.  Thus clay containing a compound of potassium may be treated with sulphuric acid, if desired after drying and pulverizing, in sufficient amount to constitute a semi-dry mass, which is brought into contact with gases containing ammonia.  The product contains the oxides of iron and aluminium, and ammonium sulphate, together with a soluble compound of potassium.  Other examples of naturally-occurring materials suitable for use in the process are alunite and shales containing iron, aluminium, sulphur, and potassium, with or without phosphorus.  Alunite may be calcined and used without any addition of acid.  Instead of sulphuric acid there may be used sulphur dioxide or trioxide, hydrochloric or phosphoric acid, spent pickling liquor or acid salts, or mixtures of any of these.  When phosphoric acid is used, gases containing ammonia may be treated in a heated condition : if however, the absorption is allowed to proceed for a long time in the cold, material containing tri-ammonium phosphate is obtained. The products may be lixiviated to remove the soluble salts, or they may be heated to about 400 DEG  C., when about 50 per cent of the ammonia present is evolved, leaving material suitable for re-use. Alternatively the ammonia may be expelled by means of lime.
