Title: Process for manufacturing spun yarn
IPC: D02G3/40
Filed: 1954-12-03
Abstract: A yarn composed of a mixture of staple fibres of polyvinyl alcohol with fibres of cotton, wool, silk, hair, hemp, flax or artificial materials, or mixtures thereof, is scoured with a selective solvent so that the polyvinyl alcohol fibres are removed.  The polyvinyl alcohol fibres may include other fibres soluble in the same solvent, e.g. slightly acetalized or esterified vinyl alcohol fibres, and may have been treated with a thermally reversible gelling agent such as boric acid, a borate or congo red.  The solvent may be hot (above 80 DEG C.) or cold water or aqueous solutions, e.g. soap solution, a solution of an organic or inorganic acid (hydrochloric, sulphuric, or acetic) or a concentrated solution of a neutral salt such as calcium nitrate or magnesium or calcium chloride.

Abstract: 1374574 Stretching films BAKELITE XYLONITE Ltd 13 Oct 1971 [21 July 1970] 35302/70 Heading B5B [Also in Division F2] An apparatus for stretching a moving web, e.g. a polythene or polypropylene web which may be heated and drawn through the apparatus by nip rolls, comprises two endless chains which extend along opposite sides of the web (only one shown) and which carry web gripping devices 9 which vary in their separation according to the degree of folding of the chains; each chain link 1 having two spaced guide members 6, 7, one comprising a wheeled carriage 8 continuously engaging a primary guiding rail 10, and the other intermittently engaging a secondary guiding rail 12, e.g. via wheel 11, to control the folding and unfolding of the chain; rotation of the wheeled carriage 8 relative to its guiding rail 10 being prevented by engagement of wheels 14 and 22 with the track.  As shown the guide members 6, 7 are the alternate pivotal connections between chain links 1. Each chain is driven by wheels 19 of guide members 7 engaging recesses 21 in the teeth of adjustable driven sprockets 2, 3 (see Division F2). Alternatively (not shown) driving chains having teeth engaging chain links 1 may be used. Carriages 8 attached to guide members 6 ride on guide rails 10 by means of rollers 22 and carry web gripping devices (not shown) on surface 20. The chains travel around sprockets 2, 3 and along the return run in the fully extended state. On leaving sprocket 2 the rollers 11 enter the flared end of a first channel 23 of guide track 12 and the chain is folded as track 12 diverges from track 10. The track 12 terminates at 16 where the chain is fully folded and begins again at 17 to control the extension of chain up to point 18. The web is engaged by the gripping devices where the chain is in the fully folded state and is disengaged after extension of the chain. The chains may diverge in the expanding section 17 to 18 to produce transverse as well as longitudinal stretching of the web. Specifications 936,935; 1,091,971; and 1,371,741 are referred to.

Abstract: In the final water cooler of a gas purification system interposed between a saturator in which ammonia is removed from the gas and a scrubber in which benzol is washed out with a wash oil, the gas entering at 24 is sprayed with water supplied from a cooling device (not shown) and in the lower section of the cooler the water is extracted with hot tar to remove naphthalene therefrom before the water is passed back to the water cooler; naphthalene containing water collects above a funnel 33 with a leg 32 which delivers it on to the bottom tray of a series of spaced horizontal trays 35, the water level above the funnel being controlled to give the water sufficient time to lose most of its entrained gas bubbles before discharge on to the trays 35; tar is supplied from a line 50 through line 51 and intermittently or continuously through one or more of lines 52 and contact with the naphthalene containing water is made on the trays 35, each tray being provided with a tar drain 42 leading into a sump at the bottom of the cooler and from where tar is withdrawn under control of a level controlling device 59; the naphthalene-free water rises to the water outlet 43 over a series of inclined trays 36 which prevent foam and entrained gas bubbles and hence tar being carried out with the water to the water cooler, the spaces under the inclined trays being provided with vent pipes 40 leading up to the gas space in the upper part of the cooler.  As shown a conical baffle 271 and a ring element 29 are arranged above the <PICT:0920780/III/1> level of the water in the funnel 33 but these may be dispensed with if the space in the upper part of the cooler is provided with a packing.

Abstract: 1,220,649. Travelling-wave tubes. THOMSON-CSF. 15 July, 1969 [16 July, 1968]. No. 35672/69. Heading H1D. In a crossed-field travelling-wave tube construction which facilitates the accurate assembly of the tube, there is contained within the envelope polepieces positioned along the interaction space formed between the delay line and the sole electrode, and the envelope is provided with windows of ferromagnetic material in register with the polepieces, to permit the association of the latter with an external magnetic circuit. As shown, portion (1) is formed by a delay line 2 ending in a curved collector passage portion 14, and sandwiched between a pair of polepieces 3 and 4 on which are mounted alumina distance pieces 5, 6, 7, 8 with projecting screws 9, 10, 11, 12 for the receipt of the portion (2) through holes tl (not shown), t2, t3 and t4, whereafter it is locked in position by nuts. Portion (2) includes the sole electrode 20, ending in a collector passage portion 26 (see also Fig. 3, not shown), and having a support 28 for an electron gun. After mounting the gun, the flange 31 of the cover-portion (3)-is welded to the flange 1d of portion (1), and evacuated through connection 36, the resulting deformation of the cover ensuring contact between the soft iron window portions 34 (only one visible) and the polepieces. Ports 37 and 38 in the cover permit the circulation of coolant, and the magnetic field between the polepieces extends into the collector passage portion leading to the collector surface, which is formed on the cover (3), (Fig. 3, not shown). The tube may be of cylindrical rather than linear geometry.

A jig for the preparation of minerals such as coal comprises at least three jigging compartments 6-7, 8-9, 10-11 arranged in series, each compartment having a screen 12, 13, 14 and each being filled with water which is forced through the screens in a series of pulses, the screen 13 of the second compartment being located at a higher position than screens 12 and 14 and the water pulses in this compartment are controlled so that the fine waste leaving screen 12 of the first compartment passes through the screen 13 and is discharged at the bottom of this compartment. The feed material is supplied to the jig via shoot 23 and the coarsest heaviest waste particles which form the layer on screen 12 are removed via paddle wheel 26 into waste shoot 24, the discharge rate being controlled by a float 27. The lighter waste is carried with the coal and middlings on to screen 13 which is about 200 mm. higher than screen 12 and jigging is carried out with less water at a higher pulse frequency and a smaller pulse stroke, e.g. 40-50 c.b.m./h. of water at a frequency of 120-160 pulses/min as compared with screens 12 and 14 where jigging is effected with 70 c.b.m./h. of water at a frequency of 60-80 pulses/min. The fine waste is discharged via outlet 28 or flap valve 80. The depth of bed on screen 13 is controlled by a float 31 which operates a by-pass valve 34 in a compresser air circuit to operate the pulse rate of the water in the compartment. The middlings and coal pass from screen 13 to screen 14 where jigging is effected and middlings are removed by a paddle wheel 40 controlled by a float 41 and the cleaned coal is discharged at 42. The front part of the screen 13 may be inclined upwardly from the level of the discharge outlet 44 of the discharge coarse waste shoot 24 to enable any coarse waste which may be carried over from screen 12 to fall back into the discharge shoot.
