Title: Improvements in or relating to a method and apparatus for unwinding yarn packages
Inventor: PARKER WALTER
IPC: B65H57/18
Filed: 1964-04-23
Abstract: 1,113,984. Unwinding yarns from packages. ERNEST SCRAGG & SONS Ltd. 13 April, 1965 [23 April, 1964], No. 16782/64. Heading D1J. As yarn is unwound overend of a yarn package it passes across yarn deflecting means in the form of a rim from which the yarn is spaced by a current of air or other fluid. In Fig. 1 the hollow rim 14 is rigid with a rotating axis 25, said rotation causing air to be drawn into the rim at 27 near the polar axis and to be ejected at its periphery 14. Fig. 2 (not shown) illustrates a modified construction in which the hollow rim has blades 31 therein for causing, on rotation of the rim, an air draught outwardly of said rim. The yarn may be urged around the rim by said air current. The air passage in the hollow rim may taper towards the periphery, the taper being such that the area of circumferentially extending section through the taper is the same for all radii of the taper.

Abstract: 922,794. Extruding pipe fittings. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 26, 1961 [May 12, 1960], No. 16810/60. Classes 83 (2) and 83 (4). An extruded tube has end parts 11, 15 of uniform wall thickness and an intermediate part 13 of uniform smaller wall thickness. A hollow billet 9, particularly of magnesium-base alloy heated to 320‹ C. and lubricated, is extruded from a lubricated container 1 between a die orifice 10 and mandrel 6, 7. The billet has a rear surface shaped to conform with a concave leading surface 4 of the extrusion ram 3, as described in Specification 732,603. During the initial part of the extrusion, mandrel portion 6 extends through the die whereby the tick leading end 11 of the tube is formed. As extrusion proceeds, the mandrel is advanced so that the thicker portion 7 enters the die orifice and forms the step 12 and intermediate part 13. Extrusion is then stopped, the ram and mandrel are withdrawn, a new billet 14 with shaped leading and trailing ends is placed on top of the original billet and extrusion is continued using the thicker mandrel portion 6 to form the rear end 15 of the tube. Longitudinal external fins may be formed during the extrusion by using a suitable die section. A plug may be subsequently drawn through the tube to give it a uniform bore with a stepped external shape.

Title: Improvements in or relating to apparatus for recording sound by modulating radiant energy
IPC: G11B7/00
Filed: 1934-06-06
Abstract: 436,905. Optical sound - recording apparatus. WESTERN ELECTRIC CO., Ltd., Bush House, Aldwych, London.-, (Electrical Research Products, Inc. ; 195, Broadway, New York, U.S.A.) June 6, 1934, No. 16850. Addition to 405,078. [Class 40 (ii)] Relates to sound-recording apparatus of the kind described in the parent Specification, comprising a pair of shutters or ribbons which modulate a beam of radiant energy under the influence of the sound currents and of a biassing direct current, in which a separate transformer is used for supplying the sound currents to each ribbon, and in which a delay circuit in the current supply path to one of the transformers effects a phase difference between corresponding movements of the ribbons. According to the invention, the direct current (which biasses the ribbons in accordance with the loudness of the sounds to be recorded, for the purpose of reducing ground noise) is so applied to the circuits containing the separate transformers that no appreciable potential difference is produced by the direct current between the ends of the transformer coils, and magnetization of the cores by the direct current is avoided. In the arrangement shown, amplified microphone currents are supplied through conductors 15, 16 and transformers 17, 28 respectively to the ribbons 5, 6 of a light valve V by means of which a record is made on a film 8, a phaseshift network N being inserted in the input side of the transformer 28 as and for the purpose described in the parent Specification. A portion of the signal currents from the conductors 15, 16, amplified at 40, is transmitted to a rectifier 42, which is connected to a condenser 43, resistances 44, 32, and a battery 31. The battery is connected on one side by a conductor 33 to the junction of equal resistors 34, 35, and on the other by a conductor 38 to the junction of equal resistors 36, 37. Resistances 20, 30, which are respectively equal to the resistances of the ribbons 5, 6, are connected as shown. By this means, biassing currents, which cause the average spacing of the ribbons to vary with the amplitudes of the sounds being recorded, are applied to the ribbons in such a manner as to avoid magnetizing the cores of the transformers. In a modification, the resistances 34 ... 37 are dispensed with, the wires 38, 33 being connected to centre tappings of the secondary windings of the transformers.

Title: Push-pull tandem nuclear reactor using a liquid fuel
IPC: G21D5/08
Filed: 1957-05-28
Abstract: 855,671. Nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. May 28, 1957 [July 16, 1956], No. 16876/57. Class 39(4). A reactor arrangement comprises a pair of identical homogeneous reactors 20, 21, each reactor comprising a vessel 22 having a critical region 23 for receiving liquid fuel and a non- critical vapour region 26 separated from the region 23 by a baffle 24 defining a non-critical annular space 25. The lower ends of the vessels 22 are connected together through conduits 32, 38, heat exchangers 33, 37 and a transfer conduit 35 having a throttling valve 36. The preferred fuel is a solution of enriched uranium phosphate and phosphoric acid in water, but uranyl sulphate or uranyl nitrate may alternatively be used. The vessels 22 are surrounded by a graphite reflector 51 having a movable portion 52 for temperature control. At start-up liquid fuel is introduced in a quantity such that the regions 23 are insufficiently filled to obtain criticality, the actual quantity being sufficient to fill one of the regions 23 up to the level of the baffle 24 and also to fill the heat exchangers 33, 37. Heating units 53 around the reflectors 51 are energised to heat the fuel such that a temperature differential is established between the reactors, whereby the higher vapour pressure in the reactor having the higher temperature displaces the liquid and the liquid level in the lower temperature reactor rises to the level of the baffle 24. Thus a condition of criticality is induced in the lower temperature reactor whereby its temperature is raised so as to be higher than the higher temperature reactor and the liquid flow is reversed. Thence the condition of criticality is terminated in one reactor and induced in the other. This cycle continues, the bursts of criticality occurring alternately in the two reactors, the interval between bursts being about 1À5 sees. The heat exchangers may be by-passed by pipes 39 and valves 40, 41. Safety lines 42 are connected through rupture discs 43 to a reservoir 45. The vapour spaces 26 contain a catalytic recombiner 29. A safety rod 31 is movable in a thimble 30 into the region 23.

Title: Rotating dynamoelectric machine with compressed air cooling
IPC: H02K9/10
Filed: 1976-04-28
Abstract: The machine consists of an iron core (13), a winding (1) which is accommodated in slots (17) and a rim (14) which conducts the magnetic flux as part of the iron core. The winding (1) has two-layer winding overhangs (2), first cooling ducts (3) being constructed between the two layers of the winding overhangs. The novel feature in this case is that axial second cooling ducts (15) are provided in the iron core, between the slots and the rim, which cooling ducts (15) together with a compressed-air source (19), a fan (20), a heat exchanger (21) and the first cooling ducts (3) form a closed cooling system in order to improve the heat dissipation. Particularly in the case of traction motors, the compressed-air cooling has the advantage that the penetration of snow, water, dust etc., into the interior of the machine is thus prevented. <IMAGE>
