Title: Improvements in and relating to machines for winding toroidal coils
IPC: H01F41/06
Filed: 1948-02-05
Abstract: 644,820. Winding toroidal coils. TELEPHONE MANUFACTURING CO., Ltd., and AYLEN, J. F. Feb. 5, 1948, Nos. 3408 and 19750. [Class 83 (iv)] A machine for winding toroidal coils has a wire magazine comprising inner and outer split concentric rings defining a closed annular wire storage space provided with peripheral apertures by which the wire is fed to and delivered from the magazine. The latter is formed rings 60, 61 split and secured by spring clips and provided with holes leading to the outside of the ring 61. In loading, the magazine is split and a closed core 85, Fig. 5, threaded thereon. The ring is then joined by the spring clips and is charged with wire 87 by resiliently supporting it on rolls 56, 58, 59 rotated by a belt 55. The magazine and the core are then ' removed and the core is clamped in a mounting 14 on a shaft 15 rotated through changespeed gearing comprising worm 16 driven from a belt driven disc 20 over which a roller 19 is radially adjusted by a screw 28. A pointer 36 indicates the setting. The direction of rotation of the disc 20 is reversed periodically by cams 37, 38 on the shaft 15 controlling gear trains, Fig. 2, not shown. The magazine is mounted between pulleys 5, 6, 7 and the wire is driven through the aperture in the ring 61 and coiled on the core, Fig. 8, not shown.

Abstract: 355,640. Heating by electricity. AKT.- GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Feb. 3, 1931, No. 3415. Convention date, Feb. 17, 1930. Addition to 353,912. [Class 39 (iii).] In a stand as disclosed in the parent Specification the plate g which supports the iron wand operates the circuit-breaker b comprises a central metal portion 1, Fig. 3, of T- section which is housed between the limbs of a forked member 2 formed of asbestos or other insulating material. When the iron is removed from the stand the member 1 is pressed by springs 3 upwardly above the remainder of the supporting plate and, since the mass of the member 1 is small in comparison with its surface area, the member cools down rapidly so that the stand quickly becomes effective to control the heat of another iron when it is placed on the stand.

Abstract: 1,204,782. Reducing iron ore. STEEL CO. OF WALES Ltd. March 25, 1969 [March 31, 1968], No.3598/68. Heading C7D. Iron ore is reduced by feeding a molten stream thereof with lime through a nozzle and atomizing the stream with a reducing gas (e.g. natural gas) and collecting the iron and slag in the chamber in which the reduction has been performed. In the fig iron ore and lime is pre-heated in a rotary furnace 10, fed into the melting furnace 15, tapped into a tundish 20, whence it flows through nozzle 21 as a stream into collecting chamber 23. The melt stream is atomized by a reducing gas fed through inlet 27 to conduit 26 and holes 28 which last provide a conical gas stream with its apex below the level of the nozzle outlet in the collecting chamber. The slag collects as a layer 31 and the iron as a layer 32. The pre-heating furnace, which may be a fluidized bed, and the melting furnace, which is preferably a cyclone furnace are preferably heated by combustion of the waste gases from the reduction chamber.

[Class 4] A tailless aircraft comprises a generally triangular plan form wing 5 of relatively thick central aerofoil section, the halves of the wing having lines of centre of pressure 15, which are swept back from root to tip, substantial taper in thickness and plan form, and are disposed at a positive dihedral angle, the sections. of each half having a substantially symmetrical basic wing profiles of substantially zero centre of pressure movement, and the chords of said sections progressively decreasing in angle of attack from root to tip. In the embodiment illustrated the wing tips 3 are deflected downwardly at a negative dihedral angle of approximately - 30 degrees to the horizontal. Control surfaces include inboard flaps 51, elevens 53, and outboard flaps 55 on the downturned wing tips serving as ailerons and rudders. The engine shafts carry fans 36 which draw air through slots 37 in the upper wing surface for supply to radiators 39. The slots 37 are placed at from 50 to 70 per cent of the chord from the leading edge where the boundary layer commences to build up at the commencement of stall, so that removal of the boundary layer delays stalling. A tricycle undercarriage 20, 21, is provided, together with a tail skid 23 which serves to house a rear machine gun 27. The central section 17 of the leading edge is of transparent material to form a windscreen, and a small window 19 in the trailing edge provides rearward visibility. Specification 1784/11, [Class 4], is referred to.

Abstract: 1, 084, 643. Regulating fluid-flow. TECHNICON INSTRUMENTS CORPORATION. Jan. 27, 1966 [Feb. 18, 1965], No.3644/66. Heading G3H. [Also in Division F2] In order to maintain a constant flow of liquid from a container 10 into an outlet 14, which is connected to the interior of the container by a flexible coiled pipe 12 of stainless steel or plastics material, the downstream end of the pipe 12 is adjustably connected to the stem of a valve 19 controlling the supply of atmospheric air to a pipe 30 leading to the space above the liquid in the container. Any change in flow-rate causes movement of the pipe 12 due to a tendency to straighten the latter so resulting in adjustment of the valve and hence variation in the rate at which air enters the container to replace liquid discharged therefrom. The liquid in the container may be subjected to a pressure head in which case the valve controls the pressure gas supplied thereto. The movement of the coiled pipe is proportional to the square of the velocity of flow therethrough.

Abstract: 719,646. Dashpots. BRATT COLBRAN. Ltd. Feb. 17, 1953 [Feb. 18, 1952], No. 4199/52. Class 108(3) A dashpot comprises a body part a having three bores b. c and s containing respectively, a spring-loaded piston d, a movable member (e.g. a valve e), and a spring-loaded tappet rod q operable by the piston d, a lever t passing through a hole in the movable member having one end in operative connection with the rod q and being adjustably supported at the other end by the body part. In the construction shown, the movable member is a valve e which controls flow of gas between an inlet passage g (not visible in Figs. 1 and 4), and an outlet passage f. A threaded plug in the passage g serves to adjust the rate of gas flow. The lever t bears on a slot in the tapped rod q, on a projection x in a transverse bore of the valve e and is fulcrummed in an eccentric recess in a plug u. The plug u may be rotated to adjust the fulcrum position. In operation, on downward manual displacement of the piston d, an arm p releases the rod q which is driven downwards by the action of a spring r. This actuates the lever t, and thereby depresses the valve e to open the port f. The return stroke of the piston d under the action of a spring i, occurs at a controlled rate due to flow through a restriction k, until the piston is by-passed by a groove m. The piston then rises quickly, and at this stage the arm p re-engages the rod q, which acts via the lever t to close e the valve e. The valve e may alternatively be a switch-actuating or other member. Specification 633,519 is referred to.
