[Also in Division H3]  A coil assembly comprises two coils 11, 12 (Fig. 1) wound at rightangles to each other on a former 10, in order to minimize the mutual inductance between them, and a ferro magnetic core member (not shown) which can move through the former 10 to vary simultaneously the coil inductances. The core member may be a ferrite. The windings 17 of the coil 12 are printed on a flexible substrate 14 (Fig. 2) provided with an aperture 19 through which access into the former 10 by the core member is made after the printed substrate 14 has been bent along the lines 19 into the shape shown in Fig. 1 and around the former 10. The ends of the windings 17 are soldered together to complete the coil and the winding 11 is secured around the coil 12 by adhesive. In an alternative embodiment (Fig. 6, not shown) the winding 15 of the coil 12 is formed as a continuous track on the substrate in order to remove the necessity of soldering the winding ends. Further ferromagnetic members extending parallel to the winding 11 may be attached to the coil assembly (Fig. 7, not shown).

Abstract: 585,861. Cables. STANDARD TELEPHONES & CABLES, Ltd., and WEBB, J. K. Dec. 22, 1944,No. 25756. [Class 36] An electric conductor is insulated with thermoplastic material, the voids in which are reduced by heating the insulated conductor under pressure, the pressure being maintained during cooling. The temperature should be only a little below the melting point of the material, and the pressure should be about 2 tons per square inch. The insulated conductor may be placed in vacuo prior to the application of heat and pressure or between two such applications. The material may be polyethylene or, according to. the Provisional Specification, polyvinyl chloride or ethyl cellulose. To apply the heat and pressure the cable is drawn into a steel tube in sections 8 with end pieces 9 and then evacuated of air and filled with water. Steam under pressure is circulated through the jacket 10 which has inlet and outlet pipes 11, 12. When the water has been heated, its pressure is increased by a pump 13.

Abstract: 338,912. Kuehnrich, P. R., and Darwins, Ltd. Aug. 28, 1929. Annealing.-Articles made from alloy irons and steels containing 8-20 per cent chromium and 1-3.5 per cent carbon with or without up to 6 per cent cobalt and up to 1 per cent each of nickel, vanadium, molybdenum, silicon and manganese and containing sulphur and phosphorus as non-essential impurities (less than 0.05 per cent of each) are hardened and rendered stainless and rustless by heating to a temperature between 1150‹ C. and 1250‹ C. and, when uniformly heated to this temperature, cooling at a definite rate corresponding to the rate at which steel in sheet form of about 18 gauge cools in water at normal temperature. This cooling is effected for articles in sheet or strip form of thickness not exceeding 18 gauge by quenching in water at 15‹ C., far articles up to 12 gauge thickness, e.g. spoons and forks, by quenching in a solution of calcium chloride or sodium chloride, and for tramcar fittings and castings generally by quenching in iced water or iced chloride solutions. The heat treatment is preferably carried out in a reducing or inert atmosphere or in a salt bath. An alternative method of cooling stamped articles is described in which the steel sheet &c. is heated to 1150‹- 1250‹ C., shaped by the dies of the press or stamp and left in the press or stamp to cool. Spoons may be formed in the usual manner from annealed sheet or strip steel containing 1.1 per cent carbon, 18 per cent chromium, 0.4 per cent silicon, 0.2 per cent manganese and 0.03 per cent each of sulphur and phosphorus and are then heated in a salt bath to 1250‹ C. and quenched singly in a calcium chloride solution at 15‹-18‹ C. The spoons after quenching are polished or buffed in the usual manner. Specifications 13414/13, 13415/13; and 106,187, [Class 82 (i), Metals, Extracting &c.], are referred to.

Abstract: 284,391. Guinness, K. E. L. Oct. 25, 1926. Sparking-plugs.-The central electrode 16 is mounted within a steel bush 12 so as to be readily removable therefrom. The casing 10 and mica lining 11 are compressed about the bush 12, which at its outer end is formed with a hexagonal flange 13. An internal thread receives the outer part 26 of the central conductor, which may merely press the main portion 16 against a flange in the bush 12, or may be combined with such main portion by means of a threaded extension inserted in a recess 27. In the construction in which the part 26 of the electrode. merely presses on the part 16, the withdrawal of the latter may be facilitated by providing a: screwed stem 27 on the part 16, which stem normally lies within an unthreaded recess in the outer part 26. At its outer end the part 26 has a threaded recess which, by reversing the part end for end, may be made to engage the screwed stem on the part 16. Removal of the member 26 is effected by means of the hexagonal portion 19, the transference of any stress to the insulator during such removal being avoided by using spanners on both portions 19, 13. By reducing in thickness the part 20 of the stem below the hexagon 19 this danger to the gas-tightness of the insulator may be further lessened. The inner end of the plug may be fitted either with a screwed ring terminal 22, or with a plain ring over which the end of the casing is turned.
