Title: An arrangement for producing a neutral tapping point in three-phase networks, for connecting up neutral point choking coils
IPC: H02H9/08
Filed: 1926-06-21
Abstract: 253,944. Akt.-Ges. Brown, Boveri, et Cie. June 30, 1925, [Convention date]. Protective arrangements.-To reduce the size of choking coils used in obtaining a neutral point for earthing a three-phase system through a damping coil, two choking coils in Scott connection are used. This renders unnecessary any extra turns for the suppression of stray fields since the limbs of the choking coils IP, PII and PO, OIII neutralize their own leakage current fields; the leakage current Je divides in the proportions and directions shown in Fig. 1. Fig. 2 shows a construction of coil in which a, a<1> form the coil IP, b, b<1> the coil PII, c the coil PO and d the coil OIII, the coil c being twice the section of the other coils. Specification 3206/01 is referred to.

Title: Method and apparatus for reduction of metal oxides
IPC: C21B13/00
Filed: 1955-05-18
Abstract: 818,236. Reducing iron and other metallic oxides. TAYLOR, C. A. May 18, 1956 [June 1, 1955], No. 15651/56. Classes 72 and 82(1) [Also in Group XII] 4 A method of continuously reducing metallic oxides to metals comprises feeding particles of oxide of size 100 to 500 mesh to a vertical reaction zone for free gravitation at descent while free hydrogen passes upwardly in contact with the particles, maintaining a temperature gradient increasing downwardly of the reaction zone from the reaction temperature to a temperature not exceeding the sintering temperature of the metal particles, adding selectively hydrogen, oxygen, or combustion air, or cooling gas to the reaction zone at a plurality of levels, and removing the metal through a cooling zone from the lower end of the reaction zone. As shown, applied to the reduction of iron ore, the ore is "supplied, preferably preheated, to a feed mechanism 2, to which free hydrogen may be added, and discharged to the top of a shaft 1 lined with refractory material and having constrictions 5 dividing it into zones A, B, C and D. Each zone is provided with gas inlets, preferably in the form of three rings each having a plurality of nozzles, those in the outer two rings being horizontal and those in the centre inclined upwardly, for the addition as required, of hydrogen, oxygen or combustion air, or a cooling gas, e.g. nitrogen, the amount of each gas being so controlled that the temperatures in the zones A, B and C are, zone C-250 to 300‹C., zone B-300 to 600‹C. and zone A-850 to 1000‹C. The iron produced in zone A falls through a restriction 5 into zone D where it is cooled by a gas at 15‹C and finally removed from the shaft to storage or to a melting furnace. The gases fed to the shaft are controlled by thermostats and control gear and the waste gases, part of which may be removed from the bottom of the furnace, may be recycled through a regenerating system.

Title: Improvements in or relating to ignition systems for internal-combustion engines
Filed: 1940-10-24
Abstract: 542,458. 'Ignition systems; sparking-plugs. BOWLES, P. Oct. 24, 1940, No. 15660. [Class 7 (iv)] An ignition system for an internal-combustion engine comprises a condenser 13 and means for charging it, an auxiliary spark-gap 15 between the condenser and the sparking-plug 17, and an impedance or non-inductive resistance 18 shunting the gap of the sparking-plug. As shown, a coil or magneto 10 is connected through a distributer 11 and screened cables 12 to the plugs, the condenser 13 being formed by the earthed screening of the cable. The resistance may be formed by a tubular member 23 surrounding but insulated from the central electrode 20 of the sparking-plug, Fig. 2 ; contact is made with the nut 24 on the upper end of the electrode 20 through a spring washer 25 and a soft conducting washer 26, while the lower end of the member 23 is in contact through a soft washer 27 with the body of the plug or with a sleeve 21 forming the outer electrode.

Patent GB-1186401-A (GB)
Title: Improvements relating to Regulating Devices for Hydraulic Drives, such as Fan Drives
IPC: F04D25/04
Filed: 1967-04-05
Abstract: 1,186,401. Hydrostatic transmissions. M. BEHR, [trading as SUDDEUTSCHE KUHLERFABRIK JULIUS FR. BEHR]. 5 April, 1967 [5 April, 1966], No. 15665/67. Heading F2D. [Also in Division F1] An hydraulically-driven fan, e.g. for cooling vehicle engines, is controlled by a flow regulator arranged between the flow and return lines of an hydraulic circuit in a line by-passing the fan driving motor. The regulator includes a thermostatically-controlled slide valve 10, Fig. 2, which increasingly closes a by-pass passage 16 between flow and return connections 15, 18 with increasing coolant temperature so that the fan is gradually driven. The slide valve may be manually adjusted by means 102. Moreover, the regulator includes a pressure relief valve 21 which permits flow through the by-pass line in the event of a high pressure being developed in the flow line due to sudden increase in speed of an engine-driven pump supplying the driving oil to the motor. The high pressure is communicated to the interior of a slide valve member 25 of the relief valve through connection 15, passages 20, 37, bore 24 and orifice 57, where it opens a control valve member 28 against the force exerted by a spring 53, which is controlled by a piston 47 subjected at its right hand end to the pressure in the return line communicated through a pipe 50. The spring force may be manually adjusted by a screw 56. The open control valve member communicates the interior of the slide valve member with the return line through passages 34, 33, 22 and connection 18. Thus, the pressure differential created across the slide valve member moves the latter to the right to communicate flow connection 15 with return connection 18 through passages 20, 37, bore 24 and passages 29, 30, 32, 33 and 22. The resulting by-pass flow permits the motor to gradually increase its speed to a value corresponding to that of the pump. Moreover, the higher pressure in the return line increases the required opening pressure for control valve 28 so that the response pressure of the pressure relief valve is automatically increased to a value suitable for the new pump speed. In an alternative embodiment, Figs. 4 and 5 (not shown), the slide valve 10 is omitted but a thermostatically-controlled pilot valve (66) when open during low temperatures communicates return line pressure to the interior (103) of the slide valve member (88) of the pressure relief valve to maintain the slide valve member open for by-pass flow therethrough. Moreover, the return line pressure is communicated to the spring biasing piston of the control valve member of the pressure relief valve through an axial bore (98) and radial ports (97) in the control valve member stem.

Title: Improvements in or relating to high-voltage gas-blast electric circuit-breakers
Inventor: ROBERTS FREDERICK ARTHUR
IPC: H01H33/70
Filed: 1960-05-06
Abstract: 946,236. Gas-blast switches. A. REYROLLE & CO. Ltd. May 6, 1960, No. 16134/60. Heading H2B. A high-voltage gas-blast switch has an arcing chamber A made of wound insulating fibre and of bulbous shape which is substantially symmetrical about an axis passing through the arcing contacts. The chamber may be substantially spherical or ellipsoidal in shape and have a flexible gas-tight rubber liner A<SP>1</SP>. The chamber may be made by winding a continuous thread of glass fibre coated with thermosetting resin on to a soft metal former supporting the liner A<SP>1</SP> and metal fittings B, B<SP>1</SP>. This assembly is then heated to cause the winding to bind into a solid mass and to bond on to the metal fittings, the metal former then being melted out on further heating. Alternatively, the fibre may be of nylon or other fibre and may be bound together with synthetic rubber or other material. If the switch is to be used out of doors an outer protective insulating coating is applied to the chamber or an outer solid shedded insulator is used. In the construction shown in Figs. 1 and 4 the fitting B carries a fixed contact assembly C comprising a spring loaded arcing contact G and radially spring-pressed contact elements G<SP>2</SP>. The fitting B<SP>1</SP> carries the moving contact assembly D which includes a moving contact F, radially spring-pressed contact elements F<SP>3</SP>, an insulating nozzle E, a piston F<SP>2</SP> secured to the contact F and a spring F<SP>1</SP> which biases the contacts into the closed position, Fig. 4, when the chamber A and an exhaust chamber H are filled with compressed gas. On the opening of an exhaust valve H<SP>1</SP> the pressure to the left of the piston F<SP>2</SP> falls so that the pressure in the chamber A acting on the right of the piston opens the contacts. A passage F<SP>5</SP> in the contact F permits an initial flow of gas to occur through the passage to stabilize the arc as the contact F separates from the contact G before the end of the contact F is withdrawn through the nozzle E to enable the high velocity blast to flow through the nozzle. This arrangement may be modified so that the contacts are opened and the gasblast occurs when an inlet blast valve is opened to supply gas to the chamber A. Each chamber A may enclose two or more " breaks." Fig. 5 shows an arrangement in which two pairs of the units described above are mounted on supporting insulators N, N<SP>1</SP> and are interconnected by a rotatably mounted isolating switch arm N<SP>2</SP>.
