Title: An improved melt spinning apparatus
IPC: D01D4/08
Filed: 1964-11-12
Abstract: 1,087,037. Melt-spinning apparatus. ONDER ZOEKINGSINSTITUUT RESEARCH N.V. Nov. 12, 1964 [Nov. 20, 1963], No. 46204/64. Heading B5B. Apparatus for melt-spinning filaments, e.g. of polyesters, comprises a heating jacket 1, a spinning pack 3 within the jacket and readily removable therefrom, e.g. from above, which pack consists of a body 3 having an inlet 13 for the molten material, a filter (e.g. of sand 8 and gauze packs 6, 7), and a spinneret 11 with a large number of spinning orifices in which the pack body and the jacket have opposed, similarly inclined, heat transfer surfaces which mate together with a wedging action. Where the pack is removable from above the surfaces converge downwardly as shown. Said surfaces may be flat, as in the rectangular construction shown, the longer opposed sides of which are inclined, or may be conical or frusto-conical. Suitably, the included angle between said surfaces is about 20 degrees, so that angle A is about 10 degrees. The pack may be elongated in section in planes parallel to the plane containing the spinning orifices, the pack having a length of between twice and fifteen times its width. As shown, a bridge 15 comprising a melt feed passage 21 extends between the jacket and the pack with the feed passage in register with the melt inlet 13 and an outlet from the jacket 16. A single fixing device serves to hold the pack in the jacket and the bridge in position, said fixing device comprising a presser member (e.g. bolt 22) which is on the one hand supported by the jacket, e.g. by way of a locking bar 23, and on the other hand presses on part of the bridge 15 above the jacket. A second presser member (e.g. bolt 26), similarly held, may be provided. To remove the spinning pack 3 and bridge 15 the clamping bolts 22 and 26 are slackened and the ears 36 and 37 of the locking bar 23 and tube 21 respectively are gripped with tongs. Attached to the closure 5 is a series of hooks 38, of which only one is shown, with the aid of which the pack can be lifted. If necessary, pack 3 can be lifted from jacket 1 with the aid of thrust bolts 39 provided in the four corners of closure 5. The jacket wall, which is in contact with the side walls of the spinning pack, may be cut away at its bottom end, at or below the level of the spinning orifices, as at 27. Fig. 3 shows a jacket 1 and spinning pack 3 mounted in a heated housing 40, in which there is also located a spare spinning pack 42 placed at a short distance from the jacket and heated by the same heat source. In operation, melt passes from conduit 13 to chamber 14 in the jacket 1, which may be heated by means of a heattransfer fluid, thence via the exchangeable bridge 15 to the main melt-inlet 16 in the closure 5 of the pack 3, and hence into the elongated channels 31, 32 which have slots 33, 34 on their lower sides and along their entire length. Hence the melt passes to the space 28 above the filter pack and thence to the spinneret orifices.

Abstract: 1,002,149. Multiply paper valve sacks. BOWATER RESEARCH & DEVELOPMENT CO. Ltd. Dec. 7, 1962, No. 46263/62. Heading B8K. A multiply block bottomed paper valve sack as in Application No. 22703/61 has a strip treated with insecticide or insect repellent secured to the internal surfaces of the end closures, the width of the strip being at least that of the end closure. The strip is applied to the closure after the end flaps have been turned in, but prior to turning in the face flaps. The valve may be formed in one with the strip by making it of a sleeve of paper treated with insecticide, of such a length as to extend from one corner flap to the other and having openings midway along its length. The openings may be parallel slits extending in the direction of the length of the sleeve and joined at their ends, remote from the inlet, by a line of perforations which are broken when the sack is filled. Alternatively, the openings may be formed by perforations in the form of an H.

Abstract: 1,247,338. Making combustible gas. POWERGAS CORP. Ltd. 3 Oct., 1968 [13 Oct., 1967], No. 46869/67. Heading C5E. In a process for catalytically steam reforming hydrocarbons to produce a gas containing H 2 , CH 4  and carbon oxides, under elevated temperature and pressure, a stream of hot gas under pressure produced externally of the reforming vessel 20 heats the reactant mixture indirectly through the walls of tubes 22 in the vessel. The hot gas is produced by combustion in a chamber 12, flows down a central tube 21 to outlets 37 into an annular space enclosing one or more rings of catalyst-containing tubes 22, see also Fig. 3 (not shown), and up to outlets 29. The reactants enter at 30, and pass through grids 43 into the tubes 22 which they leave by tubes 38 and outlet 28, which may lead to a secondary reformer (10), see Fig. 1 (not shown). The hot gas, which may comprise 80% air, enters the vessel 20 at e.g. 900‹ to 1000‹ C. at about 150 p.s.i., and the preheated reactants at about 400‹ C. and 400 p.s.i. The hot gas on leaving at 29 preheats air for the reformer (10) at (16) and traverses in turn a gas turbine (8) which drives an air compressor (9) for both reformers, a heat exchanger (3) for hydrocarbon feed, partial combustion (4) and steam raising unit (2), see Fig. I. An air line which by-passes the chamber 12 and vessel 20 contains a control valve (13). The catalyst may be in the annular space, to which the reactants are delivered, the heating gas going to the tubes 22.

Each torch holder 1 is fixed to a chain 8 looped over a rod 7 which connects the ends of spaced parallel arms 6 The other ends of the arms 6 are connected to a rotatable spindle 5 secured to a lever 9 which is biased downwardly by the spring 13 so that the torch holders 1 assume an inoperative position II. When an electromagnetic valve (19 or 20, Figs. 3a, 3b, not shown) is actuated, fluid is supplied to the lower end of cylinder 12 causing the lever 9 to be raised and the torch holders 1 to be lowered towards the operative position I until rollers 3 contact the surface of the workpiece 2. When the valve is deenergized, the torch holders 1 are raised by the spring 13, the raising being assisted by the cylinder 12 if it is double acting. In another embodiment, a spring acts on the spindle 5 which is rotatable by a motor.

The bodies may have two end collars as shown, one end collar, or several axially spaced collars, and the apertures or notches in the coil are designed accordingly. When the notches or apertures are not equally spaced about the coil, the article to be heated must be rotated about its axis. The notched portions may be formed by brazing conductive segments to the edges of the coil. A bearing made of lead-copper alloy was centrifugally cast by passing the alloy into a mild steel collared cylinder evenly heated by the indicator.
