Abstract: 199,065. Kermode, J. J. Feb. 13, 1922. Liquid-fuel furnaces.-In a vertical boiler fired with liquid fuel, the combustion chamber B, Fig. 1, is formed by a refractory lining b<1> separated from the boiler shell by an annular space C in which air supplied to the combustion chamber is heated. Air enters the space C through a non-return valve h<1> provided in a casing H and passes into a casing D surrounding the burner E and provided with a non-return air-admission valve d<2>. An adjustable cone F, casing G and refractory extension b<2> are also provided within the casing D and opening leading to the combustion chamber. The rear portion of the lining b' may be carried upwardly and forwardly to form a deflector for the gases. According to a modification, the air enters the space C through a valve at the rear of the furnace and passes directly into the combustion chamber B through lateral openings near the front. In the modification shown in Fig. 5, the burner casing is dispensed with, the burner E being mounted on the boiler shell in front of an opening e<2>. Air enters the casing H<2> through a non-return valve h<1> controlled by a regulating screw h<4> and passes in'to the annular space C leading into the combustion chamber through openings c<2>. Fig. 8 shows a modification in which the lining b' is separated from the boiler shell by a " dead " space C<1> and the air is heated in an annular duct C<2> formed outside the boiler shell and communicating with the combustion chamber through openings c<2>. This arrangement may be modified by providing passages in the shell A so that air heated in the space C<1> may pass into the space C<2>. In the modification shown in Fig. 10, air enters through valves h<1>, an annular space C<4> formed on the outside of the boiler shell and passes through openings c<5> into the annular space C and thence through openings c<2> to the combustion chamber. A preliminary heating of the air before it enters the annular passages surrounding the combustion chamber may be effected in a casing enclosing the bottom of the combustion chamber.

[Also in Division F2] An electromagnetic brake for a spindle comprises an electromagnet 23 mounted on a support 17 which is movable towards an armature 12 which rotates with the spindle. When the electromagnet is energized it moves towards the armature until it engages a brake surface thereon. Means are providd for returning the brake member to its initial position on deexcitation of the electromagnet. As shown, the electromagnet 23 is prevented from rotation by screws 10 engaging in slots in a fixed part 4 of the spindle rail. The electromagnet carries a friction lining 26 which bears against the lower face of a flange of the driving wharf 13 during braking. In Figures 3 and 4 (not shown) the electromagnet declutches the wharf from the spindle prior to braking the spindle, by first moving upwards to abut the lower end of a spindle support (53) and then pull clutch part (61) down towards itself. This clutch part (61) thereby disengages from the wharf and, being attached to the spindle, brakes the spindle as it contacts the electromagnet. In Figures 5 and 6 (not shown) the electromagnet declutches the wharf (57) from the spindle by engaging bolt heads (81) during its upward movement towards braking flange (76), thereby disengaging clutch part (77) from the wharf. In Figure 7 (not shown), the electromagnet moves upwards to bear against brake flange (76<SP>1</SP>) and pulls clutch member (94) downwards to disengage the spindle. The brake surface may be conical instead of flat as shown. It is stated that the brake can also act as a radial brake.

Title: Magnetic core material and method of manufacturing same
IPC: C22C38/60
Filed: 1927-02-19
Abstract: 290,736. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Feb. 19, 1927. Inductances.-A magnetic material which can. be readily reduced to fine particles for forming the cores of telephone loading coils &c. is produced from a nickel-iron alloy comprising at least 10 per cent of iron or nickel by adding to the molten substance an ingredient to render it brittle. According to one method, the required quantities of nickel and iron are heated, preferably electrically, in an uncovered furnace to permit oxidation, which is facilitated by the addition of iron oxide. After melting, the alloy is boiled until oxidized to a higher extent than required, and a small quantity of a deoxidizer such as magnesiumnickel alloy, aluminium, or chromium is added just before the melt is poured. After solidification, the ingot is heated to 1325‹ C. and passed progressively decreasing rolls until a flat strip about in. thick and 5 in. wide is obtained. The rolled slabs are broken up, passed through a jaw crusher,and rolled in a ball mill until reduced to fine dust. The dust is sieved through a 120-mesh sieve and any residue re-melted and again powdered. According to an alternative method, a small amount of antimony is mixed with the melted material and the alloy is poured into a shallow mould and allowed to solidify. It is then broken up and reduced in a ball mill to finely divided form. When nickel-iron alloy comprising 25 per cent nickel and the remainder a good grade of commercial iron is used, the amount of antimony required is from 5 per cent to 8 per cent, preferably about 6¢ per cent. After being reduced to dust, the alloy particles are heated to 950‹ C. for about 5 minutes and allowed to cool. They are then coated with shellac or other insulating material and moudled under high pressure into a dust ring “ in. thick and 1.375 in. inside diameter A number of such rings are stacked coaxially to form a core. Specification 124,658 is referred to.

Title: Improvements relating to aerials
IPC: H01Q1/12
Filed: 1953-02-20
Abstract: 745,437. Aerials. ANTIFERENCE, Ltd., and BEST, N. M. Feb. 22, 1954 [Feb. 20, 1953], No. 4825/53. Class 40 (7). An aerial system comprising a number of conductive elements, a quarter of the operating wavelength or a multiple thereof long, which require to be electrically connected to a support means has the parts to be connected formed with mating surfaces which are assembled with intervening insulating material in such a manner as to form a capacitor the reactance of which is low at the designed operating frequency of the aerial. The insulating material may consist of a sheet or film of plastic insulating material such as polythene held between the two surfaces or attached to one of them. In other embodiments insulating paint may be applied to one or both surfaces or, if the parts are of aluminium, the surfaces may be anodized. When the invention is applied to an X-type aerial (Figs. 1 and 2; Fig. 1 not shown), an X-shaped insulating moulding 2 is formed integrally with a central junction box 1 and each radial arm has a semi-circular groove in one face lined with a metallic element 4. The aerial rods 3 fit into the grooves but are separated from the elements 4 by intervening insulating material so that a capacity coupling is formed. They are held in place by bolts 8 and wing nuts 9. Each element 4 has a clearance hole for bolt 8 and an extension 5 passing through into the interior of the junction box 1 where the feeder and other connections are made. The use of the invention in connection with a folded dipole and a parasitic element are described with reference to Figs. 3, 4 and 5 (not shown), and in connection with a V-dipole, the angle between the elements of which is adjustable with reference to Fig. 6 (also not shown). An H-type aerial is shown in Fig. 7 arranged for vertically polarized signals. To each of the dipole elements 28 and 29 is coupled closer to the feeder junction box 30, a horizontal dipole element 31, 32 for the reception of horizontally polarized signals of higher frequency. The capacity of the coupling clips may be made such as to provide a low impedance at the higher frequency but a sufficiently high impedance at the lower frequency for the arms 31, 32 to have little effect on the reception of the vertically polarized signals. Capacity coupled parasitic elements may be provided on the cross-arm of the H for the horizontally polarized waves.
