Title: Improvements in and relating to stationary electrical induction apparatus
IPC: H01F27/18
Filed: 1955-02-15
Abstract: 764,576. Transformers. GENERAL ELECTRIC CO. Feb. 15, 1955 [Feb. 15, 1954], No. 4517/55. Class 38 (2). In a transformer or other induction apparatus, windings immersed in a liquid which evaporates under operation comprise sloping layers 20 separated by spacers 21 to form ducts between the layers, through which rise bubbles formed from the liquid, the bubbles later being condensed and returned to the bulk of liquid 11. The sloping layers 20 which constitute the high voltage winding of a transformer lie between two insulating cylinders 17, 25 whereby two vertical ducts 24, 27 are formed, the bubbles passing from one to the other between the layers, up to the surface of the liquid, finally being condensed in tubes 32. These tubes are so arranged that the condensate returns to the liquid above the duct 28 formed between cylinder 25 and transformer casing 10. The cooled liquid passes down this duct to the bottom of the transformer. The low-tension cylindrical winding 14 lies between insulating cylinder 17 and an inner insulating cylinder 13 which surrounds core 12, two vertical ducts 16, 19 being thereby formed for the passage of bubbles developed by the heat from this winding. The sloping layers are located by wedge-shaped blocks 29, 30. The relative absence of bubbles from duct 24 improves the insulation between the high and low-tension windings and in duct 27 they act as sound insulation. Fluorocarbons are suitable insulating liquids. The low-tension windings may comprise sloping layers, either formed into a separate column and sloping in the opposite direction from the hightension winding, Fig. 3 (not shown), or sandwiched two-by-two with the latter winding, Fig. 4 (not shown).

Abstract: 525,026. Alternating- current motors. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Feb: 11, 1939, No. 4580. Convention date, Feb. 14, 1938. [Class 35] A small puwer single-phase condenser type induction motor with salient laminated poles has removable solid pole-shoes, the sides of which located in the direction of the rotor shaft extend obliquely with respect to this shaft. The overall span of the pole-shoes may be about two thirds of the pole pitch. In the form shown in Fig. 1, the motor has a condenser 11 in series with the winding of two poles and each pole has a polepiece 5 with oblique sides so that the pole-pieces overlap around the periphery of the rotor, as in Fig. 3. The slots between the pole-shoes may be soldered up with copper or other non-magnetic material thus giving an annular unit which may be clamped between the poles without other means of attachment. The pole-pieces may be formed from a ring with oblique slots, as shown in Fig. 5, or rows of holes or grooves. In a modification, in place of separate pole-pieces an undivided magnetic ring rests against the poles. The rotor may be of the squirrel cage type, and the pole-pieces may be larger in the direction of rotor axis than the laminated poles.

Title: Method and apparatus for forming fibrous bundles of glass or like heat-softenable material
IPC: C03B37/04
Filed: 1962-02-06
Abstract: In the formation of a bundle of elongated fibres of glass or like heat softenable material, molten glass is delivered on to the orificed peripheral wall of a rotor, which projects the glass outwardly by centrifugal force in the form of elongated fibres, and a region of low pressure is established below the rotor substantially at the axis of rotation thereof to cause the fibres to converge towards the region and form a bundle. Molten glass 12 is delivered to the wall 22 of a rotor 16 by compressed air through pipe 30 and nozzle 32 and is projected through orifices 24 in the form of elongated fibres 26.  The fibres may be collected in this form or, as shown, may be attenuated further to fibres 60 by compressed air or steam or by combustion gases burned in a housing 36 and projected downwardly through an annular orifice 42. The rotor 16 is formed with an extension 62 coming to an apex 66 and the area 68 adjacent the apex 66 is formed with perforations, through which air is sucked by a pipe 70 passing through the rotor 16 and operating sleeve 18, terminating adjacent the top of the area 68 and connected to a suction pump.  The fibres 60 are thereby collected against the extension 62 and twisted thereby. A compacting device 72 below the apex 66 draws the bundle 78 firmly together and a pull roll 80 passes the bundle for collection on a spool 84. <PICT:0972473/C1/1>

Abstract: 412,546. Wrapping-machines. SOGNI, J., 17, Rue Diderot, Vincennes, Seine, France. Sept. 12, 1932, No. 5003/33. Divided on 402,904, [Group XIII]. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 14, 1933]. [Class 94 (i).] In a machine for wrapping sweets or like articles, the articles to be wrapped are fed by a conveyer, to a rotary device into which the articles are pushed together with the wrapping material and in which they are held by nippers which are opened by the machine as the nippers reach the picking-up position, the device being then rotated step by step, partially wrapping the article during the movement, until the article is opposite a folding passage, an extractor then removing the article from the machine and delivering it into the folding passage where wrapping is completed. Two wrapping devices may be provided side by side. An article to be wrapped 82, Fig. 3, is fed by a conveyer to the delivery tube 83, and a piece of wrapping paper is dropped from slot 100 into a position between tube 83 and the wheel 84, the relative positions of article and paper being shown in Fig. 12. Cam 127 now actuates lever 124 to raise the jaw 86 of the nipper opposite tube 83 and cam 123 actuates pusher 117, through 119, 121, to press the article and paper past folding plates into the nippers, the paper being folded as shown in Fig. 13. The nipper jaw closes and the wheel rotates, a further article being placed in the wheel at each sixth of a revolution. When the first article considered has been carried through 180‹, the wheel comes to rest with the article opposite the folding passage 131, the wrapping being then as shown in Fig. 14. The rod 158 (Fig. 9) is now moved, through cam mechanism, and by means of segmental gears 154, 155, presses the members 150, 151 together to fold down the portions of paper C, Fig. 14, to give the wrapping indicated in Fig. 15. The rod 134 (Fig. 3) driven by eccentric 133, now moves rods 136 moving the extractor arm, 141 which has been positioned behind the package to drag this from the wheel into the folding passage 131. The extractor arm is constrained to move in a to-and-fro manner. As the article is drawn into the folding passage the parts K and L (Fig. 15) are folded over giving the wrapping shown in Fig. 16 and as the article is forced through the folding passage, shown in Fig. 7, by following articles the corners are folded by slots 177, 178 giving the wrapping shown in Figs. 17 and 18. Specification 402,904, is referred to.
