Title: Self-crimping synthetic fibres
IPC: D02G1/00
Filed: 1964-03-23
Abstract: A process for producing a synthetic textile fibre having a three-dimensional, random crimp comprises drawing a pre-spun, unoriented fibre composed of a linear, high molecular weight polyester fibre-forming polymer in a liquid which is a non-solvent for the polymer and maintained at a temperature below the critical draw temperature of the polymer and thereafter heating the fibre in the absence of tension, whereby built-in stresses, resulting from the drawing of the polymeric material in said liquid are released and three-dimensional, random crimping of the fibre occurs.  The critical draw temperature is defined as the maximum temperature at which a thermoplastic material can be drawn to produce filaments that curl up or crimp in a truly random, three-dimensional manner upon release of tension from the filamentary material after drawing and during a subsequent heat treating or heat setting step.  This temperature varies for different thermoplastic materials.  Thus for polyethylene terephthalate, the critical draw temperature is about 25 DEG C., and such filaments are preferably drawn at a temperature of 1 DEG C. to 25 DEG C., especially 1 DEG C. to 10 DEG C.  Similarly, the critical draw temperature for polyesters derived from 1,4-cyclohexane dimethanol, e.g. poly (1,4-cyclohexylene, dimethylene terephthalate) is about 80 DEG C. and such filaments are preferably drawn at from 50 DEG C. to 80 DEG C., especially from 60 DEG C. to 70 DEG C. After drawing, the fibres are heated, suitably to a temperature within the range of 125 DEG C. to 225 DEG C.  If desired, the filament tow, after drawing, may be cut into staple fibres which are then subjected to the heat treatment.  Examples 1-4 relate to the treatment of polyethylene terephthalate fibres; Example 5 relates to the treatment of poly (1,4-cyclohexylene dimethylene terephthalate fibres.  Crimped fibres so made be used as filling materials for pillows, for the formation of bats and in staple form for the manufacture of spun yarn either alone or in admixture with other textile fibres, e.g. cellulose acetate, viscose, acrylic fibres, cotton, wool and other natural and synthetic p  fibres.

Abstract: 474,391. Cathode-ray tubes. BAIRD TELEVISION, Ltd., and SZEGHO, C. April 30, 1936, No. 12279. [Class 39 (i)] In an electron-discharge device in which a fasciculated electron beam is deflected in space so as to reconstitute upon a screen a television or like image corresponding with signals supplied to. the device, an enlarged electron image produced under the influence of the reconstituted image is projected upon a screen of fluorescent material so as to produce thereon an enlarged visible image of the original reconstituted image. In one form, a modulated electron beam scans a screen 3 of material having a long phosphorescent after-glow time, deposited on a transparent membrane 4. On the other side of the membrane is deposited a photo-electric layer 5, the electron image from which is accelerated by anode 8 and focused by a magnetic coil (not shown) so as to produce an enlarged image on the fluorescent end wall 7. Preferably the membrane 4 is formed as a colour filter to remove any short-period fluorescent light from layer 3. In a modification, the screen 3, 4, 5 is replaced by a screen raised to incandescence by the scanning beam and emitting electrons thermionically towards the screen 7.

As shown, part 2 is guided in a groove in outer sinker ring 3 and a recess in inner sinker ring 5, the second part 6 being slidable on nose 7 of part 2. In operation, when a needle is taking the yarn the associated sinker has its edge 9 at its lowest point.

Abstract: 494,948. Cables. ALLGEMEINE ELEKTRICITATS-GES. April 30, 1937, No. 12427. Convention date, May 12, 1936. [Class 36] In a communication cable containing high frequency coaxial conductors and symmetrically stranded conductors, both for duplex working, the symmetri cally stranded conductors for each direction of transmission are grouped into bundles of about the same diameter as the coaxial conductors and are stranded with two or more coaxial conductors to form the cable core. The conductors of the different speech directions may be separated by electrostatic or electromagnetic screens, or both. Where the space available in the cable is inadequate for accommodating all of the symmetrically stranded conductors in bundles, some of them may be applied as a layer or layers over the stranded core consisting of the high frequency conductors and bundles of about the same diameter. In the construction shown a cable core comprises coaxial lines a, b and bundles c, d of symmetrically stranded conductors, stranded together and bound by an insulating tape k. Further groups of conductors e-i fill the space with the lead sheath m not occupied by the coaxial lines a, b and bundles c, d. Specification 457,280 is referred to.

Abstract: 1456351 Centrifugal casting PONT-A-MOUSSON SA 26 March 1975 [1 April 1974] 12551/75 Heading B3F In a casting machine for centrifugally casting iron pipes, in which the mould is cooled by water from primary cooling tubes parallel to the length of the mould, local overheating of the mould which may cause inhomogenous structures is overcome by additional secondary water spraying. A centrifugal casting machine comprising a carriage A movable on runway C has a mould 2 rotatable by rollers 7 driven by motor 8. Three fixed water spraying tubes 10, two above the axis X-X of the mould 2 and one below, are disposed longitudinally in casing 1 near the outer surface of the mould 2. The tubes 10 are supplied with water through pipes 11, 13 through T-pipe 31 connected to mains water 32. A longitudinal guide bar 14 which may have a square section, rotatable in bearings 15 is located in the lower part of casing 1, and may be maintained in different angular positions by a pin 16 and hole 19 arrangement. Slidably mounted on bar 14 are two slides 20, carrying rigid pipes 21, the upper ends of which being secondary water sprays 22 parallel to and slightly above axis X-X of mould 2 when operative. Water is supplied to sprays 22 via rigid pipes 24 connected to flexible hoses 25 through connectors 28. Hoses 25 pass through the upper wall of casing 1 and are connected to mains water 32 by means of valves 30, which may be manually or electrically operated. Drainage pipes 33 permit the cooling water to be removed from the assembly. Sprays 22 and their associated pipes 24 may be released from connectors 28 and rotated out of position, Fig. 3 (not shown), and the location of slide 20 on bar 14 may be adjusted to accommodate varying sizes of moulds 2. In operation, when excessively hot portions are noted on cast pipes, slides 20 are moved along bar 14 to the required location, and the pipe moulds are further cooled by the secondary sprays 22. In a modification a photoelectric cell 34, mounted on the pouring channel B detects the abnormally hot zones and signals valve 30 to supply water to the secondary sprays 22. In a further modification, two guide bars 14 may be provided on opposite sides of the mould 2, each with two secondary spray assemblies.

[Class 75 (i))] [Also in Group XII] A gas turbine combustion chamber comprises inner and outer chambers 1, 2 forming between them an annular space 3 for cooling air, a burner body 10 through which the primary air passes and a cylinder 5 through which the oil-laden primary air from the burner 12 passes which cylinder has external vanes 6 to impart whirl to secondary air entering the inner chamber 1. The inner chamber has a restriction ring or quarl 4 to increase the local velocity of the air and to deflect the air into the oil spray issuing from the nozzle 12. The vanes 6 whirl the secondary air in the opposite direction to that of the oil spray. The quantity of air passing through the cylinder 5 is controlled by a flame cone 7 operated by a draw rod 8. Oil is supplied to the injector 16 through a cock 14 having a safety device 15 to prevent unscrewing of a cap 17 and removal of the injector 16 until the oil supply is cut off. When the injector 16 is removed a balanced or manually operated flap 18 prevents high pressure air entering the engine room. The oil injector 16 is held in position by a cone piece 20 forming part of the cock 14. The combustion chamber is suitable for burning fuel oil, mixtures in which coal is held in suspension in oil, creosotes or creosote and pitch mixtures.
