Patent GB-611623-A (GB)
Title: Improvements in or relating to the production of fibres, particularly glass fibres
IPC: C03B37/04
Filed: 1945-12-21
Abstract: A body, rapidly rotating about a vertical axis for forming fibres from organic material heated to a viscous state and centrifugally projected through orifices in the periphery thereof, consists of two plates joined at their edges along a circumferential portion forming a corner, of little or no vertical height, wherein the radially directed projection orifices are arranged; turbulent external air currents opposing the centrifugal action and causing premature solidification are thereby avoided. Gas currents may be projected simultaneously from above and below to produce a resultant drawing current whose mean plane coincides with that of the projected viscous streams, or the material within the rotor may be heated just sufficiently to allow of centrifugal extrusion, the drawing into fibres being carried out in a further heating zone, through which the streams pass for a short part of their paths before being cooled by atmospheric air.  The <PICT:0611623/IV(a)/1> <PICT:0611623/IV(a)/2> <PICT:0611623/IV(a)/3> rotor 1 shown in Fig. 3, comprising two shallow spherical caps whose common periphery 4 carries the projection orifices 5, is mounted on a hollow pulley-driven shaft 6 coacting with an injection cone 9 to feed an internal burner 8, whose flames spread towards the periphery and then return to be evacuated by a central opening 10 or by a number of openings 42, Fig. 12.  The material to be treated, e.g. cold and in the form of small balls, is fed in through the opening 10, or may be catapulted through a central tube arranged within the driving shaft 6; the latter may be arranged above the rotor 1.  The periphery 4 may form a sharp corner as shown, or a rounded or truncated corner, or the rotor may comprise two discs set slightly apart and joined at their edges by a narrow band carrying the orifices, Fig. 6, not shown. In Fig. 8, two series of radial nozzles 16, 17 are arranged to project air jets producing a resultant current 18 centred about the plane xy of the viscous streams, a sufficient space being left between the orifices 15 and the zone of contact with the air jets to avoid premature cooling thereby; two walls 21, 22 may be provided to canalize the air current, and the nozzles 16, 17 may be partially or wholly tangential to the rotor periphery, or may themselves be rotated coaxially thereto.  In Fig. 12 the orifices 32 exercise a drag on the comparatively cool material which coacts with the atmospheric friction on the already attenuated fibres to promote an increased drawing action in the short intermediate heating zone above gas flames 39; the column of hot gas rising from these flames and from the rotor interior may be used to form the fibres into a network 43 for gathering on to a mandrel or on to a stationary cylinder arranged coaxially or a rotating cylinder arranged horizontally above the rotor; webs may be produced on a cylinder having suction applied to perforations therein, and the fibres may be coated.

In all the forms shown, the coils d surround the laminated core g at the ends of which are mounted three-limbed magnetic plates l, m angularly displaced from one another by a rotor pole pitch. Three magnetic axial bars n, o, p abut against the limbs of plate l and extend down to the permanent magnet and between them are three axial bars r, s, t abutting against the limbs of plate m, so that the six bars which are embedded in the casing complete the magnetic circuit. In the form shown in Fig. 5, the star-shaped permanent magnet c rotates and is coupled to its shaft b by a spark advancer consisting of two centrifugal arms pivoted on it and having their ends adapted to engage teeth on a bush on the shaft. In the inductor magnets shown in Fig. 7, the magnet c is stationary and six magnetic pieces are cast into the distributer c<1> which is coupled to the shaft by a device as described above. In an alternative form, the stationary magnet is bellshaped with its limbs cast in the housing and enclosing the flux distributer. A shaft extending through the hollow armature core serves to operate the contact-breaker i and distributer for the secondary current. The magnet may have any suitable number of limbs and axial bars, whilst the casing may be of insulating material. The Specification as open to inspection under Sect. 91 comprises also laminated tips for the ends of the magnet arms secured thereto by cast non-magnetic material. This subjectmatter does not appear in the Specification as accepted.
