Patent GB-496782-A (GB)
Title: Improvements in and relating to centrifugal gas cleaners
IPC: B04C3/04
Filed: 1938-01-28
Abstract: 496,782. Centrifugal gas - cleaners. TRIGGS, W. W. (Centrifix Corporation) Jan. 28, 1938, No. 2725. [Class 23] To separate liquid particles from the gas in which they are suspended, the stream of gas, while whirling about a vertical axis, is divided into a number of thin whirling streams by concentric cylindrical surfaces. The liquid forms films upon these surfaces and falls from their edges to a discharge outlet while the whirling gas passes through a vaned space to its outlet. A number of separator units A are arranged in parallel between an inlet main B and an outlet main C. The tangential inlet 3 of each unit is connected to the main B by a small pipe and valve A<1>, while the gas outlet A<4> of each unit is connected to the main C by a pipe C<2> and valve A<2>. Any unit can therefore be isolated for cleaning. The diameter of the casing of each separator is twice that of the inlet nozzle 3, and the cover 5 of the casing supports a central tube 7 which holds a nest of concentric thin walled cylinders 8 with a conical spreader 9 at their lower end provided with vanes 10. The parts 5, 7, 8, 9, 10 form a single structure, and the aggregate cross-sectional areas of the passages between the cylinders 8 are greater than that of the inlet nozzle. The cylinders are partly telescoped to provide marginal top portions 8b for the reception of the whirling gas. The base 6 of the casing carries a pipe 17 which supports a separating element with blades 19 to direct gas into the pipe. The gas passes from the inlet 3 to the expansion space 12a at the top of the casing, and while whirling passes down the space 12 and the spaces between the cylinders 8 after impact upon the marginal portions 8b. Liquid particles are thrown outwards and form descending films on the cylinder walls and the casing. The gas and the liquid drops enter the space 15 from which they pass between the vanes 10 which augment the whirling motion. The gas passes between the blades 19 of the separator 22 where further liquid particles are thrown outwards and the clean gas passes down the pipe 17 to the outlet A<4>. The liquid separated in the first part of the separator drops down the casing to the body T of liquid and the gas near the casing keeps the liquid stirred. The liquid from the separator 22 joins the same body T by means of tubes 20, 21 and is discharged from its container through the pipe A<3> to the discharge trough R. Cooling or heating liquid can be supplied to the tube 7 by means of pipes 26, 27, and the base 6 may have a heating jacket 28. Separating units may be arranged in tandem between the mains B, C.

Title: Joining textile webs
IPC: D06H5/00
Filed: 1964-01-24
Abstract: In order to produce a flat stitched butt seam in a textile web, the exposed portions of the sewing thread are pressed into the faces of the fabric, and are adhesively heat sealed to the faces of the fabric by a thermoplastic component of the sewing thread. The thread comprises at least 1% of a thermoplastic component having a flow temperature of between preferably 125 and 200 degrees, and at least 30% of a component which neither flows not deteriorates when heated to said temperature.  The seam is subjected to a pressure of from 25 to 200 lb per sq. inch, preferably from 50 to 100 lb per sq. inch, depending on the materials, to embed the exposed threads into the web, the seam area is heated, while under pressure, to a temperature at least 25 degrees C. above said flow temperature, the temperature is maintained for up to one minute normally from 2 to 35 seconds, and the seam is then permitted to cool.  If the thermoplastic component is non-fibrous, it may comprise from 1 to 40%, preferably from 3 to 30%, and may be present either as a coating on a thread, or by being distributed around the individual fibres of the second component.  It may include plasticized, partially polymerized phenolformaldehyde resins, polyurethanes, polyvinyl acetates, polyvinyl butyrates, polyvinyl chlorides, acrylic monomers and methacrylic polymers.  If the thermoplastic component is fibrous, it may comprise from 20 to 70%, preferably 50%, and may be in filament, multi-filament or staple form, separate from or blended with the second fibrous component.  It may include polypropylene, polyethylene, polyvinyl alcohol, polyvinyl acetate, cellulose acetate and other thermoplastic derivatives of cellulose, polyvinyl butyrates and the lower melting nylons.  If the textile web is to be subsequently subjected to a heating operation, the thermoplastic component may be a material which becomes thermo-setting upon heating, such as the aminoplats and phenoplasts. Preferably the second fibrous component is non-thermoplastic, e.g. cotton, rayon or wool, but nylons, ethylene glycol, terephthalic polyesters, acrylics and other relatively high melting thermoplastic materials can be used when the flow temperature is at least 25 DEG C. above the flow temperature of the first component.  U.S.A. Specification 3,600,434 is referred to.

Title: Improvements in or relating to the formation of tubes from organic plastic material
IPC: B29C48/09
Filed: 1948-02-04
Abstract: 668,723. Extruding tubes of organic thermoplastic material. BRITISH XYLONITE CO., Ltd. Feb. 4, 1948 [Aug. 4, 1941], No.3299/48. Class 87(ii) Differences in the temperature and viscosity of plastic material may be compensated by adjusting the width of a slot 85 through which the material passes in the extrusion head. The extruded tube may be closed at its lower end and blown into contact with a mould as described in Specifi. cation 564,350 to form a hollow article. Plastic material from a heating chamber enters the extrusion head at 51 and flows through a series of openings, see Figs. 4 to 7 (not shown), so that it is) split up into 16 streams which pas: through fine holes in a web 82, Fig. 8 (not shown). The material then flows through the slot 85 into a chamber 86 and is extruded at 58. If the material becomes hotter and thus less viscous at one side, this is corrected by adjusting screws 95 to rock ring 92 and increase the width of the slot 85 at the appropriate side, thus increasing the flow and therefore decreasing the heating of the material at this side. Air is supplied to the tube through an air tube 62 mounted in a spherical member 68. The position of the air tube may be adjusted by screws 70b, which rotate the spherical member 68, to vary the wall thickness of the plastic tube. This movement of the member 68 is so small as not to affect the adjustments made to the width of the slot 85 by means of the ring 92. Whilst adjusting the position of the member 68, the pressure exerted on it by members 66, 67 may be relieved by adjusting screws 87. The extrusion head is heated by circulating oil between the threads of a screw 54, and the air tube may be internally cored for the passage of a heating medium. The extruded tube may be closed by raising the air tube 62 and simultaneously lowering a plunger 88 to apply an impulse to the plastic material in the chamber 86. In a modified apparatus, Figs. 9 to 12 and 14 to 20 (not shown), the position of the air tube 143, Fig. 9, is adjusted by four horizontal set screws, and the slot 85 is replaced by a slot 160 the width of which is adjusted by screws 165. This modified apparatus has the advantage that the flow resistance ring 161 may be easily removed.
