Abstract: 1,263,337. Collecting and folding sheets. SCHNELLPRESSENFABRIK KOENIG & BAUER A.G. 10 Feb., 1969 [11 Sept., 1968], No. 7115/69. Heading B8R. A collecting cylinder is provided with five sets of collecting pins or grippers around its periphery and is associated with sheet-removal means at two positions spaced at 120 degrees around its circumference, the arrangement being such that, regardless of whether sheets are collected or not, there are breaks in the flow of sheets through either of the sheet-removal means to allow subsequent folding devices to run at reduced speeds. Fig. 1 illustrates apparatus in which a web 1, which has been printed by a plate cylinder having four different pages on its circumference, is severed by cutting cylinders 2, 3 to produce sheets corresponding to each page, which are transferred to collecting cylinder 4 provided with five equally-spaced sets of pins or grippers. Transfer cylinders 5, 6 are spaced 120 degrees apart around the periphery of cylinder 4, and are associated with folding cylinders 17, 18 which deliver the sheets to positions DI, DII, DIII, DIV. An alternative arrangement (Fig. 4, not shown) provides cutting and folding blades on the collecting cylinder. Operation of the pins or grippers is controlled by a stationary cam 7 fixed to the machine, and a rotating cam 11 on the end face of cylinder 4 (also Figs. 2 and 3, not shown), the pins being withdrawn or the grippers opened only when corresponding recesses in the cams are aligned. Three modes of use are possible: (i) non-collecting production where alternate sheets are transferred to cylinders 5 and 6, and are delivered to respective positions DI, DII, DIII, DIV; (ii) single-collection where cylinder 5 is inoperative, and two sheets are collected on cylinder 4 before transfer, the first pair being delivered to position DII, the second pair to position DIV; (iii) double-collection where all four sheets in a set are collected on cylinder 4 before transfer, are transferred to cylinder 6 and delivered at location DIV. In each of these modes of use there will be a break in the stream of sheets being fed to a particular folder, so that it can operate at reduced speed.

Title: Apparatus and process for the production of drawn filaments
IPC: D01D4/02
Filed: 1965-02-22
Abstract: 1,107,861. Melt and dry spinning apparatus. CARL FREUDENBERG. 22 Feb., 1965 [22 Feb., 1964], No. 7552/65, Heading B5B. In a spinneret the extrusion orifices are arranged in a straight row, there is a slot for the discharge of air (preferably at least as long as the row) along either side of the row and a uniform distance away from the row and there are passages within the spinneret for supplying air to the air slots. Each passage includes a constriction or constrictions effective to reduce or eliminate variations along the slot to which it leads in the pressure of the air leaving that slot. In the embodiment of a spinneret according to the invention, the spinneret illustrated in cross-section in Fig. 1 is constructed of an upper part 1 and a lower part 2. The part 1 is an elongated steel plate having a ridge 3 of trapezoidal cross-section extending along its centre over its entire length. A number of orifices 4 arranged in a row along the tip of this ridge communicate with a common polymer supply duct 5 for all the orifices. The spinneret includes two air chambers 6 and from each air passages 7 lead to air slots 8 along the sides of the orifices 4. Each passage 7 leads into and out from a passage chamber 9 and there is a bar 10 extending into each passage chamber 9 throughout the length of each chamber. This bar 10 serves both to provide a constriction 11 in the passage when the passage leads out from the passage chamber and also as a baffle 12 for so deflecting air entering the passage chamber from the air chamber 6 that air cannot pass in a straight path through the passage chamber 9. There is a further constriction 13 in each passage 7. The apparatus of which the spinneret forms a part may include an elongated guide duct 15 illustrated in perspective in Fig. 4. The duct is open both at its upper and lower ends and its width at least equals the length of the row of orifices in the spinneret. The duct is arranged to receive the filaments extruded through the spinneret. The length of the guide duct is so chosen that the friction between the air streams flowing concurrently with the filaments and at a higher linear velocity than that of the filaments acts on the hot filaments for a sufficient period of time to draw the filaments to the required degree. As the open top of the duct is spaced from the spinneret, secondary streams of air or other gas 17 are drawn into the duct by the injector action of the filaments and of the primary air streams discharged from the spinneret slots. The filament sheet after leaving the guide duct may be deposited on a support surface to form a fleece of non-woven fibres which may be drawn by suction on to a suitable mould to be formed into a non-woven fabric.

Title: Improvments in the production of alloys of high zirconium content
IPC: C25C3/00
Filed: 1949-03-21
Abstract: A method for the production of zirconium alloy consists in the electrolytic precipitation of zirconium from fused electrolytic salts containing zirconium whilst a molten metal which is to form part of the alloy is employed as a cathode, the electrolysis being stopped before the melting point of the zirconium alloy has risen to the boiling point of the cathode, and the cathode metal then being distilled off to increase the zirconium content of the alloy.  As an example of the method, a melt containing 28 per cent potassium chloride, 22 per cent sodium chloride and 50 per cent zirconium tetrachloride is electrolyzed (see Group XXXVI) at 750 DEG C. so as to produce an alloy containing 15 per cent zirconium and 84.5 per cent zinc.  When the alloy is heated in a finely pulverized state at about 800 DEG C. the zirconium content may be raised to 98 per cent. A similar melt but containing also magnesium chloride may be used to produce a zirconium-zinc-magnesium alloy containing 12 per cent zirconium, 80 per cent zinc and 8 per cent magnesium.  This alloy can be heated to result in a metal containing 40 per cent zirconium, 45 per cent zinc and 15 per cent magnesium.  An alloy of zirconium, magnesium and zinc or cadmium may be produced by first obtaining the alloy of zirconium and zinc or cadmium and then after distilling off part of the zinc or cadmium dissolving the alloy in melted magnesium. Zinc zirconium alloy and cadmium zirconium alloy may be dissolved together in melted magnesium to produce a magnesium-zinc-cadmium-zirconium alloy.
