Abstract: 16,357. Blondel, A. Aug. 11. Means for absorbing mechanical shocks.-The core of a shunt solenoid used in an arc lamp is connected to the piston 37, Fig. 4, of a dash-pot 21, which has a flap valve 39, and also a conical valve 41 ; the valve 41 is attached to a rod 42 and adapted to slide in a tube 40. At the moment that a pin releases a brake wheel the valve 41 is lifted, by reason of the rod 42 striking the bottom 36 of the dash-pot, which is provided with a strengthening-rib. Free movement of the mechanism for bringing together the carbons and striking the arc is thus permitted.

Abstract: 13,547. Blondel, A. June 17, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Dynamos, regulating; motors, controlling. - Relates t o methods of exciting and regulating sychronous motors for traction purposes &c. which have the usual collectors or fixed collectors and rotating brushes, and h a v e their stators and motors fed independently by mono- or poly-phase currents, the methods being also applicable in some cases to generators. The feed-currents of the stator and rotor may be taken from the same source at the same or different tensions. The principle of the regulation consists in increasing the feed tension of the rotor at starting and at small speeds and in regulating its value and phase so that it nearly counterbalances the electromotive force generated in the rotor by the inductive effect of the slip, so that energy is driven back from the rotor into the stator or into the main ; or, by exciting the rotor, energy is driven back from the stator into the rotor or the main. Diagrams are shown by means of which it is stated that the value and phase of the starting feed tension can be calculated. When the setting of the brushes may be varied, the excitation is varied partly by altering their position and partly by altering the feed tension by means of transformers ; the phase of the exciting- current supplied to the rotor may otherwise be varied by the use of a commutator which alters the connections of the brushes with the transformers. Preferably, however, the changes in the phase of the feed-current of the rotor are produced by means of transformers or autotransformers which regulate both the phase and tension of the current. These transformers &c. may be the same as those which feed the stator. In a simple case, self-induction bobbins having movable cores are placed in the leads which connect the mains to the rotor. The feed tension is increased as desired by withdrawing the cores when starting. Fig. 3 shows a case in which the rotor R of a two-phase motor is supplied from transformers T , T , connected to the mains L , L , L , L to which the stator X is directly connected. Each transformer has two secondary coils which are connected to the rotor through switches F', F', m , m in such a manner that any desired number of windings of the coils S , S , s , s can be put in the circuits. The connections may also be reversed by the use of pole-changers. Three transformers are employed in the case of a three-phase motor as shown in Fig. 4. In this case a fixed and a variable electromotive force, differing by a quarter period of phase as in the case shown in Fig. 3, are supplied to each brush B &c. of the rotor by the fixed or constant secondary s &c. of the transformer p &c. and by the alterable secondary S' &c. of the transformer P' &c., so that a current of high tension may be supplied to the rotor at starting. The transformers of each pair may be united in one, if desired. The position of the brushes in any of the above cases is stated to be calculated from the diagram, as the lag of the brushes and of the feed tension are additive as regards their effect on the phase of the current in the rotor. The brushes, being set, do not require to be moved, as they are fed with a fixed electromotive force sufficient to cause the formation of a field equal to the normal field with no load, and also with a variable electromotive force which can be adjusted to produce the torque required. It is also shown by means of a diagram how a three-phase motor may be regulated by the use of two or three-phase excitations. In addition to the above and similar methods of altering the phases of the feed tensions, the current inlets to the stator or the setting of the brushes may be altered to produce similar results. The stator X in the case shown in Fig. 3 is provided with regularly-spaced terminals a, b, c, &c. for this purpose. The alteration of the connections may be made by means of controllers which connect the supply leads to the proper wires of a number leading to the points a, b, c, &c. The tension and phases of the currents supplied to the stator may be altered by means of transformers which supply the current, the magnetic flux and the torque being then adjustable. In slowing down the motor, the direction of rotation of the field both in the stator and rotor is reversed, but may also be maintained in its original direction while the rotor is still moving. For this purpose, the applied electromotive force is set slightly in advance of that induced in the stator, and is regulated at a value a little greater than that of the electromotive force in the rotor, so that it increases as the slip increases. The slowing down may finally be hastened by reversing the fields. It is stated that the motor speed may, when necessary, be increased beyond synchronism by giving the applied electromotive force a lag of about half a period. The phase and tension regulator may be placed in the stator circuit instead of as described above, or the stator may be used as an auto-transformer to supply currents of the desired phase and tension. The regulator applied to the rotor may also be some of the windings of the transformer which supplies both the stator and rotor. A similar arrangement is shown by the dotted lines in Fig. 3, the stator being then fed from the secondaries S , s of the transformers T', T ; these secondaries may feed both stator and rotor. All the arrangements described may be used in combination with means for the employment of starting-resistances and for reducing sparking, the resistances being cut in temporarily, if desired, between successive positions of the switch contacts. The phase or tension of the current from a generator is stated to be regulated by regulating the generator in accordance with the general principles of the systems described above.

Abstract: 28,297. Bloudel, A. Dec. 7. Lighthouse and like lamps.-In apparatus for producing two or more revolving beams from a single light source a comprising a concave reflector b and two or more inclined plane reflectors c, d which rotate about a vertical axis, the reflectors c, d are so arranged that the axes of the issuing beams of light make unequal angles with each other in an horizontal plane. The reflector b is preferably parabolic, and the light source a is placed at its focus. The reflectors c, d, Fig. 1, form a wedge and are bounded by an imaginary cylindrical surface passing through the periphery of the reflector b. When three reflectors c, d, d , Fig. 2, of equal area are employed, their point of intersection is outside the axis of rotation. The reflectors c, d are supported on a plate m which may revolve on rollers, or be carried by a shaft with a footstep bearing, or may form part of a float in a water or mercury bath. The light source a and the reflector b may also be rotated. An aperture t is provided in the reflector b for the passage of combustion products.

Abstract: 14,741. Blondel, A. June 24. Arc - lamp electrodes. - A flame-arc electrode consists of inner and outer zones, both made with carbon paste, of such compositions that the inner burns less readily than the outer, and the end of the electrode remains convex. If the inner zone is of pure carbon, it is made relatively small. In one type of electrode, the inner zone contains a smaller proportion of mineral matter than the outer; for instance, the inner and outer zones may have diameters of 12 to 15 and 22 millimetres and contain 30 to 40 per cent and 40 to 70 per cent of mineral matter respectively. Preferably, the percentage of mineral matter in the inner zone is not more than four-fifths of the percentage in the outer zone. A heavilymineralized outer zone may be thinly covered with pure or lightly-mineralized carbon which burns at the same rate as the outer zone when the air has access to the electrode. The inner zone, especially if star-shaped in section, may contain little or no mineral matter and be reduced in diameter, say to 0À25-0À35 of the external diameter of the electrode. Such an inner zone becomes impregnated with mineral matter during burning. One or more heavilymineralized star-shaped or other cores 3 may be arranged in the inner zone, or a heavilymineralized layer may be placed between the zones. A single core may have a diameter of 4 to 6 millimetres. Both zones, as well as the core, may be of star-shaped section. Suitable mineral materials are oxides, carbides, fluorides, borates, cerates, silicates, tungstates, molybdates, titanates, manganates, or ferrates of alkali or alkaline-earth metals, manganese, cerium, lanthanum, titanium, tungsten, or boron. The outer zones may contain 25 parts of calcium fluoride, or of a mixture of calcium and cerium fluorides, 2 of calcium or barium borate or tungstate, 3À5 of alkaline borates, 5 of alkaline silicates, 16 of gas or petroleum coke, 5 of lamp-black, and 16 of tar or pitch. For the inner zone, a larger proportion of coke is employed. Cores may consist of the same mineral substances without coke or lamp-black,- or with lamp-black only; thin tar, silicates, gum, or dextrine may be used as binding- material. In another type of electrode, the mineral matter such as carbide of titanium or tungsten in the inner zone is less volatile than that in the outer one. For instance, 'the inner zone may contain 35 parts of titanium carbide, 25 of calcium fluoride, 1 of potassium borate, 2 of sodium borate, 7 of sodium silicate, and 2 of potassium silicate, while the outer zone consists of 25 parts of cerium fluoride, 10 of calcium fluoride, 3 of alkaline borates, 1 of calcium borate, 9 of alkaline silicates, 1 of boric acid, 40 of gas-retort carbon, 6 of lampblack, and sufficient tar or pitch to agglomerate the mixture. In the latter mixture, the alkaline borates and silicates may be replaced by tungstates or molybdates of the alkaline metals or rare earths, and in either mixture they may be replaced by cryolite. The two zones and the outer coating, if any, may be made simultaneously, holes being left for cores if required. A wire a, a' may be inserted in one zone or each, or the electrode may be electro-plated. Specifications 17,406/02, 6060/03, and 6061/03 are referred to.
