Title: Improvements in and relating to Refractory Metallic Electrical Conductors for use in Incandescent Electric Lamps and the like
Filed: 1907-07-18
Granted: 1908-04-16
Abstract: 16,530. British Thomson-Houston Co., [General Electric Co.]. July 18. Bending; drawing; rolling; working by electricity; wire.-In making electric conductors of tungsten or the like for use in incandescent lamps and other apparatus, the metal is worked while heated in air to a temperature below redness at which it is ductile and does not appreciably oxidize. Coherent bodies of the metal may be obtained by mixing the latter as a powder, prepared by the reduction of the trioxide by hydrogen, with warm cadmium amalgam, cadmium-bismuth alloy, or cadmium-bismuth amalgam, squirting the mixture while warm through a diamond die or otherwise shaping it, baking the resulting bodies in a vacuum to remove part of the binding-material, and heating them by passage of current in a vacuum or inert gas completely to purify them. Wire thus obtained may be wound into a helix on a mandrel 1; Fig. 1, of platinum or other material, heated by a gas flame or an electric resistance coil. Alternatively, electric current may be passed through the wire or mandrel. The mandrel may have a shallow helical groove, the wire being sufficiently elastic when cold to allow of its removal therefrom. Wire may be made by passing a rod of the metal between hot grooved steel rolls and then drawing it through a series of heated dies, which may be of diamond. Reels on which the wire is wound are also heated. Electric-lamp filaments may be made of wires stranded together and, optionally, shaped before sintering. Fig. 6 shows apparatus for shaping a filament and for simultaneously attaching it to leading-in wires if required. The filament is placed between the curved surface of a movable block 16, which may be supported by a blade spring, and the upper edge of one of two plates 15 serving to guide the block: The block is heated electrically or by a gas flame. The leading-in wires are coiled round the ends of the filament and compressed on to them between flat parts 23 of the block and plate. Heated pliers may alternatively be used for the compression, and leading-in wires may be formed into loops 11, Fig. 4, instead of coils.

Patent GB-190718582-A (GB)
Title: Improvements in and relating to Protective Devices for Electric Systems
Filed: 1907-08-16
Granted: 1908-08-13
Abstract: 18,582. British Thomsom-Houston Co., [Allgemeine Elektricitõts Ges.]. Aug. 16. Distributing.-A faulty section in a system of distribution is rendered "dead" by automatically opening line switches placed at each end of the section, by means of relays placed in an auxiliary circuit which must be closed at two points before the line switches can be operated. The main line switches s, s<1> are held closed by magnets e, e', while relays r, r<1>, preferably of the watt meter type, are connected to the line or section through potential transformers d, d' and current transformers e, e<1>. Each phase may have a similar arrangement. When current is flowing in one direction in the section, one of the relays r, r<1>, say r, is closed and the other r<1> is open ; but if the direction of the current in the section is reversed, the relay r is opened and the relay r<1> closed. Should fault occur in the section k, current flows from each end towards the fault and both relays r, r<1> are closed, thereby completing the auxiliary circuit containing the battery f and relays g, g<1> ; these in turn close the circuits containing the magnets l, l<1>, which operate to open the main switches s, s<1>. In the modification shown in Fig. 2, the auxiliary circuit h, has a metallic return h<1>, while each relay has two contact - arms. When no current is flowing in the conductor k, the arms m, m<1> bridge the contacts p q, p<1> q<1>, while the arms d, d<1> do not contact with the contacts a, a<1>. When a current is passing through the conductor k, the arms assume the positions shown in Fig. 2; but if the section p is earthed, current enters at both ends, the arms d, d' contact with the contacts a, a<1>, and the arms m, m<1> bridge the contacts n o, n<1> o<1>, thereby energizing the coils g, g<1> to operate the main switches s, s<1>. If the section k is earthed and the line to the right of it is broken, current enters it from the left, and the auxiliary circuit is closed by the arm d contacting with the contact a, the arm m bridging the contacts n, o and the arm m<1> the contacts p<1>, q<1>. The coil g will then be energized, thereby opening the main switch s. If the fault to the right of the section is rectified, current flows from the right into the section and causes the switch s<1> to be operated ; or, both may be opened. An earth return for the auxiliary circuit may be employed. In another modification, the main relays shown in Fig. 2 may be simplified by employing additional relays, for closing the contacts p q, p<1> q<1> when the relays are de-energized, and opening them when the relays are energized, both relays being controlled by a single relay. The auxiliary circuit may be fed from the power mains, and the switch-releasing magnets placed directly in the auxiliary circuit. The invention may be employed to cut out any one of a number of transformers working in parallel.

Title: Improvements in or relating to Jet or Surface Condensers
Filed: 1907-10-21
Granted: 1907-12-19
Abstract: 23,192. Soc. Anon. Westinghouse, and Leblanc, M. Nov. 8, 1906, [date applied for under Patents Act, 1901]. Condensers.-A condenser comprises a number of superposed condensing- compartments 4, 5, 6, 7, and a series of cones 2, 8, 9, 10 acting as ejectors. Successively-increasing pressures are thus obtained in the compartments 4, 5, 6, 7, thus allowing of the use of the same condensing water in each compartment with a consequent successively-increasing temperature. The vapour undergoes a reversal of direction in part at each cone and thus enters the several compartments. The principle is applied both to jet and to surface condensers. In order to provide for the exhaustion of air from each compartment, either ejector condensers, Fig. 3, may be used, or additional cones 28, 29, 30, Fig. 4, of a smaller angle of convergence may be provided, the air being exhausted at the upper end of these cones. In a jet condenser, Fig. 3, the air is cooled on its way to the air-pump suction 15 by means of an annular jet of water 19. In a surface condenser, Fig. 4, an air cooler 26 is formed in the air-pump suction, and drain-pipes 21, 22, 23 are also provided in each compartment. Under certain conditions, the condensing-water discharged from a condenser acting on this principle may be of higher temperature than the incoming vapour.

Title: Improvements in Turbo-electric Generator Systems.
Inventor: BERG ERNST JULIUS
Filed: 1908-07-08
Granted: 1908-12-10
Abstract: 14,538. Berg, E. J. July 8. [Patent of Addition to No. 8522, A.D. 1908.] Elastic-fluid turbines.-Relates to the system of coupling steam turbines and dynamoelectric generators described in Specification No. 8522, A.D. 1908, and consists in certain improvements by which one turbine rotor is driven at a lower speed than the others and drives a synchronous polyphase generator ; the other rotors driving induction generators. In the arrangement described, two turbines, having oppositely-running rotors 3, 4 and 5, 6 are connected in series by the steam-pipe 30. The rotor 3 is mounted upon and drives the shaft 10 of the induction generator 7. The rotors 4, 5 are mounted upon, and together drive, the shaft 11 of the induction generator 8. The rotor 6 is mounted upon and drives the shaft 12 of a synchronous polyphase generator 9. The generator 9 is excited by a continuous-current generator 21, and supplies polyphase current of a fixed frequency to excite the generators 7, 8. For this purpose the leads of the three armatures are connected to common bus-bars. This connexion also forms an effective electric gearing between the three generators. The invention provides that the rotor 6 shall run at a lower speed than the other rotors, and to this end the generator 9 is constructed with six field poles while the induction generators are wound for four poles. The speed of the generators 7, 8 is determined by that of the generator 9 and consequently the governor mechanism controlling the admission of steam to the turbine is driven from the shaft 12 of the generator 9. The governing-devices shown comprise a governor 35 driven from worm gearing 33 and operating a pilot valve 36. The pilot valve controls an hydraulic motor 37, the piston of which moves a cam shaft 38 to regulate the number of nozzle sections in service. Fig. 2 shows a construction of the right-handstage of the turbine, in which the slow-running rotor 6 is of much larger diameter than the rotor 5. The steam is directed from one rotor to the other by the intermediates 32, which, however, do not reverse the direction of the flow of the steam so that the rotors run in opposite directions. If the difference in diameter of the rotors is not great, the intermediates are dispensed with.

Title: Ingot-casting Machines and Methods of Preventing "Piping" of Ingots.
Inventor: HOWARD LESLIE ELWOOD
Filed: 1908-11-04
Granted: 1909-05-06
Abstract: 23,592. Howard, L. E. Nov. 4. Casting; castings.-To prevent piping in ingots, particularly in such as are to be used for making steel tools, pressure is applied directly after pouring to a degree sufficient to prevent molten steel from flowing from the upper to the lower portion of the ingot. When the ingot has become solid throughout, the pressure is increased and maintained until the steel has cooled below the point of recalescence. The moulds are formed with two sides in a block 12, Fig. 1, with sides 15 held up by springs 36 advanced by rods 34 linked through equalizing-bars 43, 41, to an hydraulic piston 39, and with sides 17 adapted to be advanced by plungers 8 for the compression and with bottoms 25 pivotally mounted for motion, as shown in dotted lines in Fig. 2, under the control of a cylinder 30. The block 12 is held in place by plates 13 engaging recesses, and pins 16 prevent the sides 15 from dropping out when pressure is released. The ends of the springs 36 engage lugs to retract the cross-head 18 on the return stroke and the cross-head is connected by keys 23 and bolts 21 to the sides 17. When the sides are retracted and the bottom is swung down, the ingot drops clear away from the press.
