Title: Improvements in and relating to Protective Devices for Alternating Electric Current Distribution Systems.
Filed: 1907-09-05
Granted: 1908-09-03
Abstract: 19,883. British Thomson-Houston Co., Clinker, R. C., Wedmore, E. B., and Woodbridge, J. E. Sept. 5. Electro-magnets.-To avoid transformer action in electro - magnetic switches having series and shunt coils, a compensating electromotive force is obtained by separate inductively-arranged series and shunt windings in opposition to that obtained by the winding on the switch magnet. The solenoid a has a series coil b and a shunt coil c, while the solenoid d of the compensating-device is also provided with differentially - wound series and shunt coils e, f connected to the secondaries of the current and potential transformers g, h, Fig. 3 The solenoids a, d are provided with movable cores i,j suspended from a beam k pivoted at k<1>. The beam k is provided with an adjustable balance weight l<1> at one end and a bridge contact m at the other, the contact m dipping into mercury cups to close the circuit of a trip coil when the beam k is depressed. To produce no change of force by the potential coils on the cores by change of position of the cores, the coils are placed upon the upper parts of the series coils, the spaces at the bottoms being filled up by washers e'. The potential windings of the relay and compensating - device may be arranged in parallel, when a steadying resistance or impedance h<1> would be required. This resistance may be omitted in the series arrangement shown in Fig. 3, unless required for influencing the phase relation of the flux induced in the potential winding of the device. The balance of the transformer action may be improved by connecting a resistance h<1> in series with the potential coils, or additional turns may be provided on the coils e,f or an external balancing coil may be used, composed of a few turns of the reactance or the current and potential coils may be interwound. The Provisional Specification states that the transformer action may be eliminated in the same way in devices having rotary armatures or the like and series and shunt windings.

Title: Improvements in Separating Sulphurous Acid from Combustion Gases.
Inventor: BABE JULES
Filed: 1907-09-06
Granted: 1907-12-12
Abstract: 19,973. BabÚ, J., and Pape, H. Sept. 10, 1906, [date applied for under Patents Act, 1901]. Smoke and fumes, treating.-Sulphurous acid is separated as a saturated solution from combustion gases by cooling them to below 0‹ C. to condense the water vapour. If necessary, a certain quantity of water in the form of a spray or as steam, or else a solution of a salt which is not affected by sulphurous acid, may be added to absorb the whole of the sulphur dioxide and form a saturated solution on condensation, which will not freeze to ice. The process may be effected by passing the gases through a chamber filled with ice, or over a surface flooded by a cooling-liquid or kept cool by the evaporation of ammonia or sulphur dioxide.

Title: Improvements in or connected with Commutating Dynamo Electric Machines.
Inventor: FYNN VALERE ALFRED
Filed: 1907-12-05
Granted: 1908-12-03
Abstract: 26,911. Fynn, V. A. Dec. 5. Armatures; commutators; sparking, preventing. -In continuous-current and alternating-current dynamo-electric machines in which each armature coil is provided with intermediate commutator connexions C, Fig. 1, and corresponding additional commutator segments, auxiliary conductors are placed within the armature in inductive relation to the intermediate commutator connexions for the purpose of reducing the self-induction of the latter, the circuit or circuits of the auxiliary conductors being completed outside the armature of the machine. The intermediate commutator connexions are also screened from external inductive effects due to the armature, the field, or the commutating windings. In one construction, Fig. 3, the armature A is provided with a number of openings d adapted to receive the intermediate connexions and the auxiliary conductors, which latter may take the form of copper tubes f joined by copper rings i, forming a sort of squirrel cage. Brushes applied to the rings i, or to slip-rings m, are connected through a suitable low-resistance conductor. The slip-rings may be built up of a number of segments corresponding to the number of openings d, brushes of suitable width being provided thereon ; or the segments may be permanently inter-connected. The screening effect may be enhanced by disposing an ordinary squirrel cage on the outside of the openings d in holes in the armature body. The currents may be collected from the shaft h itself, or from slip-rings not insulated from the shaft ; and the conductivity of the latter may be increased by placing copper conductors in contact with the shaft between the current-collecting places and the ends of the conductors f. In place of the tubes f, any other conductors may be used, and more than one intermediate commutator connexion per coil may be provided. To assist the commutation, an alternating electromotive force may be supplied to the auxiliary conductors. The source of this electromotive force should be non-inductive, and may be either a neutralized alternating-current generator with alternating-current excitation directly coupled to the dynamo-electric machine, or a direct-currentexcited generator having its field winding connected in series with the armature of the dynamo-electric machine. In another modification, the circuit of the auxiliary conductors may be closed over a condenser, a step-up transformer preferably being interposed. Both slip-rings may be located at the same end of the armature, and the condenser may be attached to the shaft and may be allowed to rotate therewith.

Title: Improvements in Shuttle Brake Mechanism.
Inventor: LAFORET JEAN
Filed: 1908-01-08
Granted: 1908-08-20
Abstract: 497. LaforÛt, J. Jan. 19, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Looms, checking shuttles in.- In shuttle-brake mechanism of the type described in Specification No. 16,001, A.D. 1907, the tongue I, Figs. 1 and 2, is not hinged to the arm G, but carries a plate i abutting against a guide i<1> and traversed by a screw e'. A spring e<2> may be provided, and the movement of the tongue is regulated by a screw e<3> . The tongue is thus freely mounted and is capable of assuming such a position that it bears with its whole surface against the greater part of the length of the shuttle. The arm G engages a slot in an angular part g, the horizontal member g' of which is connected to an adjustable spring a and carries a rod d<1>, against which the connecting - rod C bears at the moment of throw. At the arrival of the shuttle, the arm G is moved close to the shuttle box by a spring a', and springs K, e<2> force the tongue into the box. When the rod C bears on the rod d<1>, the arm G is moved so that the spring K no longer bears on the tongue. In a modification, necessitated in some looms by the position of the catch P, the parts g, g<1> are fixed to a shaft h, Fig. 3, bent at h<1> and carrying an arm engaging under the catch. In a similar form, the arm G is dispensed with, and the spring K is fixed to the tongue and acted on by a screw carried by the part g. In the form shown in Fig. 9, a lever n with a bearing m<1> pivots on a shaft m<2>. A roller o, on a shaft carried by the bearing m<1>, contacts with the spring K fixed to the tongue, or with an incline on the tongue. The lever m is rocked through a connexion with the connecting-rod C, and consequently the pressure on the tongue is varied. The lug P of the catch may be raised by any suitable means such as, for example, an incline on the end of a rod carried by a ring s. A further modification consists in obtaining the movement of the part g by means of a roller u engaging an inclined or curved surface t fixed to the loom frame.

Title: Improvements in Gripping Devices for Rope Haulage
Inventor: DAVENPORT CARL
Filed: 1908-03-10
Granted: 1908-10-22
Abstract: 5346. Davenport, C. March 10. Rope grips for use in attaching wagons, tubs, &c. to travelling wire ropes are constructed of two jointed sections having wedge-like surfaces adapted to be engaged by a metal loop attached to the load. Fig. 2 is a cross-section of the clip, and'Fig. 4 is a plan view. The two steel or other metallic castings a, b are hinged above the rope A by a pin d. On the lower side of the casting a, an undercut wedgeshaped surface e is formed, and on the other casting b a rounded extension f is provided, being bored at an angle corresponding to the wedge e. A metal binding-loop H has one member h<2> rounded so as to fit the bole in the boss f, the other member h<1> being of rectangular cross-section and fitting the wedge surface e. The rear or wider end of the loop is bored to receive a swivel hook for attaching the load, the resistance of which causes the loop to be drawn backwards and forces the clip sections a, b into engagement with the rope A. The clip is disengaged by forcing the loop H forwards, or by swinging it about the circular member h<2>, this being effected either by a lever bar or by a blow. The forward end of the clip may be provided with ridges g to facilitate its passage around guidepulleys. An automatic disengaging-gear is shown in elevation in Fig. 5. As the clip approaches the point at which it is to be disengaged, it strikes a pair of levers k arranged one on each side of the bauling-rope. These levers are pivotally mounted on a bracket m, and their upper ends are connected by a link l to a pair of hammer-levers i, which strike the back of the clip and release it.

Title: A Process and Apparatus for Boiling, Washing, Bleaching and otherwise Treating Textile Materials in a Circulating Bath.
Inventor: WEISS ROBERT
Filed: 1908-07-18
Granted: 1908-11-05
Abstract: 15,284. Weiss, R. July 18. Bleaching; washing. - Textile materials are bleached, boiled, washed, &c. by first impregnating the materials with the bath of treating-liquid, preferable from below upwards under pressure, then, by reversing the flow, draining the liquid off and, lastly, throwing the same liquid in above to percolate through the material, the draining being continued. The apparatus used comprises two closed or open treating-vessels a, b connected together and with a pump h through a four-way reversing-cock e and a three-way cock k, and may have an overflow pipe for each vessel a, b of either of two different kinds v, t, each being provided with a back-pressure valve w, u. In operation, the vessels a, b having been charged with the material to be treated which rests on perforated bottoms or strainers l therein, the treating-liquid is fed through a pipe i, the threeway cock k, the suction nozzle j of the rotary pump h, the pump itself, its exit nozzle f, the fourway cock e, and a pipe c, into the vessel a which it fills, passing up through the material and through an upper pipe m, an intermediate vessel o, and another upper pipe u, into the second vessel b. The air is driven out of the first container a through a cock p, and when the liquid overflows into the second vessel b its admission is checked by turning the three-way cock k so that the suction nozzle j communicates through a pipe g, the fourway cock e, and a pipe d with the bottom of the second vessel b. If the material therein offers resistance to the percolation of the liquid, the latter flows through the overflow pipe t. The liquid is now heated by a steam coil q in the intermediate vessel o, and when it begins to boil a cock s in the upper pipe m is closed and the four-way cock e is turned so as to reverse the current. The second vessel b is now filled from the bottom by the liquid from the first vessel a, any air present being driven through the cock p. The upper pipes n, m being again reached, the cock s is opened. The apparatus being empty of air, it is only necessary to reverse the current by means of the four-way cock e from time to time. When the treating-vessels a, bare open, the upper connecting-pipes m, n are connected to points below their upper edges ; the intermediate vessel o may be admitted.
