Patent GB-492305-A (GB)
Title: Improved contacting process and apparatus
IPC: B01D3/30
Filed: 1937-03-18
Abstract: <PICT:0492305/III/1> In the centrifugal treatment of fluids a rapidly moving stream of gas (or vapour) is restricted to move with a whirling vortical and spiral movement and a film of liquid is fed radially across the base of the vortex so that the liquid is atomized and retained within the gas stream from which the liquid products of the contact are subsequently separated and discharged.  The process is applicable to the fractional condensation of hydrocarbon vapours which constitute the gas stream, by means of water &c. constituting the liquid film.  Oil is vaporized in a still A and injected through pipes 7, 9 into the base of a column with vortical motion imparted by a tangential distributing head 91, heavy acids being separated by a flanged cylinder 11. The vapours rise through <PICT:0492305/III/2> a series of treating units 4 to which condensing liquid, e.g. water, is supplied in controlled amount through pipes 15, 16, the separated fractions being withdrawn through pipes 18 and passed through coolers 25.  Each unit 4, Fig. 2, comprises a cylindrical shell in which is mounted a tuyere 5 provided with a series of closely spaced tangential blades 5a and supported on a flange 5f and cylindrical wall 5g forming annular passages 32, 5n, 5p, with the tuyere 5, the outer wall 4 and a dished element 5i.  The base of the tuyere 5 is closed by a seating 5c having a central opening 5c1 covered by a deflecting plate 5q and joined to the pipe 16.  In operation the vapours flow upwardly through the annular passage 32 and are deflected by the blades 5a to form a vortex against which the liquid introduced through pipe 16 is sprayed in a film formed by the deflecting plate 5q.  The liquids are separated from the vortex by contact with the outer wall 4 and the dished element 5i, and, collecting in the annular passages 5n, 5p, are removed through the pipe 18.  The supply of liquid to the pipe 16 is controlled by a valve comprising a disc 17 coacting with a seating 171, the disc being mounted on a valve stem 27 made of a metal of low coefficient of expansion which, in conjunction with the larger expansion of the metal shell 4, provides a limited thermostatic control of the valve opening.  Adjustment of the valve opening is made by a squared end on the stem 27 extending beyond a packing box 29.

Patent GB-403845-A (GB)
Title: Manufacture of dyes and intermediates therefor, and sensitization of photographic emulsions therewith
IPC: C09B23/06
Filed: 1933-03-20
Abstract: Polymethine dyes which are sensitizers for photographic silver halide emulsions are made by causing a quaternary ammonium salt corresponding with the general formula:-- <FORM:0403845/IV/1> wherein R stands for alkyl or aryl, R<1> for phenylene or naphthylene, Y for oxygen, sulphur or selenium and X for a suitable anion such as Cl, Br, I, So4CH3, ClO4, to react with a trialkyl ester of ortho-a -thiophenic acid. Reaction is preferably carried out in the presence of a condensing agent or a solvent and the products are tricarbocyanine dyes containing an a -thienyl radicle attached to the central carbon atom.  When used for sensitizing photographic silver halide emulsions they are used in amounts of 15--30 milligrams per kilo emulsion, and are added for example, in the form of their alcoholic solutions to the finished but not cast emulsion, or by coating the cast but not dried emulsion with such solution, or by bathing the finished photographic material in such solution; they sensitize towards the long-wave region of the spectrum and possess two absorption maxima.  In examples 2-methylbenzoxazole ethiodide, 2-methylbenzthiazole diethylsulphate, 2-methylbenzselenazole diethylsulphate and 2-methyl-a -naphthothiazole diethylsulphate are condensed with ortho-a -thiophenic acid triethyl ester in the presence of pyridine and in the latter three cases the dyes are precipitated in the form of their bromides; sensitizing properties are given.  Ortho-a -thiophenic acid trialkyl esters are prepared by subjecting one mol of a -iodothiophene to the Grignard reaction and causing the product to react with one mol of a tetralkyl ester of orthocarbonic acid.  The preparation of the triethyl ester is described in an example.

Title: Process and apparatus for the manufacture of nets of non-woven threads
IPC: D04H3/12
Filed: 1974-02-25
Abstract: 1435058 Non-woven nets PAPETERIES DE PONT-AUDEMER 25 Feb 1974 [28 Feb 1973] 8431/74 Heading D1R In the production of non-woven nets, threads 5 are drawn from stationary bobbins 3, conveyed through tube 4, and formed into a warp array by comb 6 whilst weft threads 8 are drawn from bobbins 7, through holes in disk 9 and through apertures in an endless chain 10 and laid spirally around the warp by the rotation of 7, 9 and 10 about tube 4; the weft threads are severed at one or both edges and one or two nets formed, the angle which the weft threads make with the warp being increased by moving the warp threads forward by amounts which increase progressively from one edge of the net to the other. In the embodiment of Figs. 1-4 the warp threads are arranged in two planes separated only by a small vertical distance and chain 10 moves in an oval path around the planes. Adhesive from path 13 is applied to the threads by roller 12 and the weft array is severed at each edge by rotary cutters 14, 15 thereby forming upper and lower nets which are separated and led around rolls 16, 17 respectively. In the case of the upper net pairs of nip rolls 21, 22 are disposed on a line parallel to the wefts. At the line of these rolls the direction of travel of each warp thread is rotated through an angle alpha which is the angle the weft threads make with the perpendicular to the warps. The net is thereby converted from a lozenge-shaped mesh to a rectangular e.g. square shaped mesh and the width of the net increased thereby maintaining tension in the wefts. If a hot melt adhesive is applied the conversion to a rectangular mesh may be carried out at a later stage, following a heating step, bobbins 26, 27 may be used to supply additional warp arrays. In a modification a single net of double width is produced by using a single cutter 14 and by opening and then spreading out the doubled array. In the embodiment of Fig. 5 (not shown) the conversion to a rectangular mesh is produced by passing the net over a hemispherical roller (25) thereby introducing a warp retardation that decreases linearly from one side of the net to the other, simultaneously the net is laterally stretched. In the embodiment of Fig. 6 (not shown) the net passes through a nip, over a fixed curved rod or a flexible bowed roller (28) and then through the nip of a second pair of rolls, the curved rod or roller adjusts the distance travelled by each warp so that the mesh becomes rectangular. Simultaneously the net is laterally stretched. Where the threads are thermoplastic they may be bound by fusion or ultrasonic waves instead of applying a binder. The net may be used to reinforce paper or plastics. The threads may be of natural or synthetic material, plastics or glass.
