Title: Improvements in the manufacture of coated electrodes for electric arc welding and other processes of fusion deposition of metals
IPC: B23K35/04
Filed: 1930-10-24
Abstract: 371,422. Uniting by fusion. TURNER, B., 9, Richmond Avenue, Wolverhampton, and FERRO-ARC WELDING CO., Ltd., 12, Grosvenor Gardens, London. Oct. 24, 1930, No. 32031. [Class 83 (iv).] An arc welding electrode is provided with a coating by first enclosing the material, in paste, powder, or fibre form, in a tube of thin covering material and then applying the tube to the metal core so as to obtain a coating of substantially equal thickness all round and along the core. The tube A may consist of paper, vegetable, or animal membranes or sheets of a substance sold under the registered Trade Mark " Cellophane," and the filling B may consist of a mixture of asbestos powder or fibre and fluxing substances, and if necessary, also powdered metals or alloys. The tube may be wound on the core in a closed spiral or an open spiral winding of asbestos yarn may be first applied and the tube then wound on to fill the intervening spaces. The tube may also be applied longitudinally of the core in one or more strips which are pressed on the core to give a complete and even coating. The tube may be of circular, or approximately rectangular section or flattened out in the form of a tape. The material of the tube does not materially affect the welding process but in the case of Cellophane causes the formation of reducing gases.

Abstract: 1,139,984. Securing impellers on shafts; bearings; lubricating. IMC MAGNETICS CORP. 12 July, 1967 [20 Dec., 1966], No. 32069/67. Headings F2A and F2U. [Also in Divisions F1 and H2] In an electrically-driven fan, an assembly comprising an induction motor rotor 21, a fan impeller 26 and a connecting sleeve 29 having a porous bearing 35 fixed therein, is mounted on a stationary shaft 18. The assembly is secured against axial movement by a snap ring 36 and associated spacer washers 37, and by an axial thrust bearing formed by the end 44 of the shaft and a nylon disc 41. The latter is mounted in a cap 38 secured axially by a snap ring 43. The impeller is preferably of plastics material. The outer surface of portion 30 of sleeve 29 has serrations thereon to secure the impeller 26, and the sleeve is cemented to the rotor. The sleeve is of good heat-conducting material, e.g. aluminium, and has an exposed flange 31 so that heat is transmitted from the bearing and rotor, through the sleeve to the air surrounding the flange. The porous bearing may be formed by sintering a mixture of graphite and bronze powders. The bearing, a contacting felt ring 39 and a felt pad 40 are loaded with lubricating oil and are so arranged that during fan operation excess oil flows centrifugally from the bearing into the pads. If the bearing becomes dry it absorbs oil from the pads which can be recharged by a syringe through a hole 46. The oil also lubricates the thrust bearing 41, 44.

Filed: 1923-12-27
Abstract: 230,572. Austin, G., Macfarlane, J. C., and Macfarlane, W. A. Dec. 27, 1923. Exciting. - The field winding of a constantcurrent motor having fixed brushes is connected in a circuit derived from the main constant-current supply, in which circuit is also connected in opposition the armature of an auxiliary dynamoelectric machine driven by the main motor, the field winding of the auxiliary machine being connected in series with the motor armature. The field winding 6, Fig. 1, of the motor 1 and the armature 11 of the auxiliary machine are connected in series across an adjustable resistance 5 in the main circuit, or a fixed resistance may be used such as a field winding or brake-magnet coil, and a separate potentiometer may be connected as a shunt to this resistance. This arrangement produces a drooping speed-torque characteristic. If it is desired to obtain a higher normal speed with a similar characteristic, a shunt 21 may be provided for the field winding 16 of the auxiliary machine, the resistance of the potentiometer may be increased, or an adjustable resistance may be provided in the field circuit 6. Fig. 4 shows a potentiometer 25 by means of which the speed and direction of rotation of the motor can be controlled. Fig. 6 shows a modified arrangement for maintaining full torque over a wide range of speed. The auxiliary machine is provided with an additional field winding 16<a> connected so as to oppose the main winding 16. Further modified characteristics may be obtained by providing extra field windings on the motor or auxiliary machine and connected in shunt to either of the armatures.

Spheroidal graphite cast iron is prepared by introducing magnesium or magnesium alloy containing more than 40 per cent Mg into a liquid bath of cast iron from an apparatus arranged outside the treatment vessel and having one or more points of introduction located at the bottom or the lowermost part of the side walls of the vessel, the reagent being introduced in regulated small quantities and without any explosive reaction. As shown, a vessel 10 has fitted to the bottom a nozzle 14 connected to a vessel 13 containing liquid magnesium. Pressure gas from a container 18 may be used to supply molten magnesium from the vessel 13 to the vessel 10. A mechanical system, e.g. a piston, may be used instead of the pneumatic system shown. If the pressure gas is reactive towards magnesium a buffer gas may be employed between pressure gas and magnesium. The nozzle, Fig. 5, may be of refractory material, e.g. magnesium oxide, and has a large diameter top with a narrow portion below the top, bores 32 in the narrow portion communicating with the supply of molten magnesium through a central bore 31. The container 15 may be heated electrically or by gas and magnesium may be added to it in the liquid or solid state through an air-lock 12. Pyrometers 17 and 16 may be used to control the temperatures of the cast iron and the magnesium respectively.

The material 6 getters undesired impurities either during its deposition or in a subsequent heating stage carried out at a temperature low enough to avoid dopant shifts in the body 22. An apertured photo resist etch mask 7 is then provided, contact apertures and interconnection channels are etched in layer 6, and an overall coating of contact metal 13, is applied to a thickness less than that of the protective coating 6. The photoresist 7 and overlying contact metal 14 is then removed to leave metal 13 in the form of interconnections and contacts all below the surface of the protective coating 6. In arrangements with multilevel interconnections the surface is bevelled with further insulating material before the next interconnection level is formed. The part circuit shown comprises a transistor and a resistor, may be formed of silicon, use phosphosilicate glass as gettering and protective material 6, and have aluminium metallization. Slight diffusion of phosphorus from coating 6 into P-type areas is stated to assist ohmic contact in the Si-Al system.
