Title: Improvements in or relating to Apparatus for Measuring Phase Differences on Electric Alternating Current Circuits
Inventor: GRAMMONT ALEXANDRE
Filed: 1902-06-30
Granted: 1902-09-17
Abstract: 14,538. Grammont, A. Dec. 20, A.D. 1901, [date applied for under Patents Act, A.D. 1901]. Testing.-An apparatus for measuring the phase difference of two synchronous alternating electric pressures by a zero method, consists of a phasechanging device having a part which may be turned through a measured angle, to produce a balancing pressure differing to a known extent in phase from one of the original pressures, so as to be in the same phase as the second original pressure, and of resistances or other means for equalizing the balancing and second pressures, using volt-meters as indicators. Several arrangements of phase-changer are specified. That shown in Fig. 1 is a transformer having a stationary core C provided with star-connected coils, which are supplied with three-phase currents from mains L<1>, L<2>, L<3> ; a core B, which may be turned through a measured angle, carries corresponding secondary coils, any pair of which may be connected to a volt-meter V<1>. The second pressure is obtained from either of three main-current transformers t<1>, t<2>, t<3>, and is applied to a volt-meter V<2> ; the secondaries of these tranformers t<1>, t<2>, t<3> have adjustable contacts, by the use of which the indications of the volt-meters V<2>, V<1> are equalized. The core B is turned until an intermediate volt-meter V<3> shows no deflection ; the complement of the angle through which the core is turned then represents the difference in phase between the pressure on, and the current in, any one of the mains L', L<2>, L<3>. The apparatus may be simplified somewhat. With a single alternating current known means are used to produce a rotating field. Another arrangement of phase-changer consists of a Gramme ring, provided with three fixed equidistant connections to the three-phase mains ; contact-arms are movable round the commutator of the ring, to take off pressures with any phase differences. Two such arms only may be used, and the angle between them may be altered to vary the amount of the pressure taken off ; for this purpose the two arms are connected by bevel-wheels with a rotatable bevel pinion on an intermediate arm. This arm carries a pointer to indicate phase differences on a stationary dial. Another phase-changer, Fig. 3, consists of three straight non-inductive resistances r<1>, r<2>, r<3> arranged at 120‹ apart, having the inner ends connected together, and the outer.ends connected through three adjustable resistances g', g<2>, g<3> to the three-phase mains. A contact e<1> at the centre of a graduated arc G slides along one of the straight resistances, without any turning of the are ; an arm rotatable on the arc carries a second contact e<2> on another of the straight resistances, the balancing pressure being taken from the two contacts. This arrangement of resistances may be used with a three phase transformer.

Abstract: 15,058. Imray, O., [National Malleable Castings Co.]. July 7. Couplings, automatic.-Relates to couplings for gravel cars and the like, and is shown in sectional plan and vertical section respectively in Figs. 1 and 2. The coupling-links 2, pivoted on pins 3, have extensions 21 which are held in the locked position by engaging against tumblers 4, as shown in the right-hand parts of the Figures. The tumbler 4 is supported in this position by a projection b, and has trunnions d, which move in grooves 5 concentric with a spindle 6. The spindle carries a hooked crank 8 which, as the spindle is turned from either side of the car by means of the handles 9, first moves the tumbler out of the recess 7, and then raises it until the projection c rests on the lip 11, as shown in the left-hand parts of the Figures. The coupling-links can now be unlocked either by hand or by drawing the cars apart, so that the extension 21 comes into contact with an inclined part g and moves the tumbler backwards into a position from which it can afterwards drop into its original position. The coupling- links can also be unlocked by further rotation of the spindle 6, by which a key 10 engages a slot f and presses a projection h on the tumbler against the extension 21 to move the coupling-link, after which the tumbler drops back into its original position. The spindle 6 is placed in position by passing the key 10 through a slot 10<1> so arranged that the spindle cannot be removed while the tumbler remains in the coupling. The spindle has two pieces 12,13 with which the handles 9 engage, and the removable piece 13 is held in position by a stop 14.

Title: Improvements in Dynamo Electric Machines for Regulating the Charge and Discharge of Storage Batteries used in Combination with Main Generators.
Filed: 1903-07-17
Granted: 1904-06-02
Abstract: 15,811. Lancashire Dynamo and Motor Co., and McLeod, R. S. July 17. Dynamos and motors combined as transformers. -Relates to the regulation of the charging and discharging of storage batteries used in conjnnction with dynamos in distributing- systems, so as to maintain a constant main generator output with a varying load, and consists of improvements in the devices shown in Specification No. 14,373, A.D. 1902, wherein a booster was provided with a winding, such as d, in combination with current and voltage windings. In the diagram, D is the main generator, E the exciter, G the booster, N the battery, and H a resistance. The exciter has two field windings, one a carrying a current which varies as the main current, and the other b, in opposition thereto, which varies as the main voltage. The exciter is driven by the booster motor. The booster has two field windings, the one c from the exciter, the other d, connected as a shunt across the booster terminals, in which the current varies in magnitude and sign according to the difference between the battery voltage and the main voltage. The booster field may also be assisted by a winding s of few turns connected in series with the battery and adapted to compensate for the voltage lost in the booster armature as the battery current increases. In modifications, this extra winding may be placed on the exciter instead of on the booster, and the winding d may be added to the windings a, b on the exciter. Instead of the wind. ing d, a differential winding may be used, consisting of a coil in which the current is proportional to the main voltage, and a coil in which it is proportional to the battery voltage. In another modification, no exciter is used, the booster field having windings carrying currents respectively proportional to the main current, the main voltage, and the difference between the main and the battery voltages. In all cases, the ends l, m of the winding a and of the connection to the booster terminal p are arranged to slide on the contacts of the resistance H, so that the proportion of the main current in the coil a can be adjusted. Any portion of the resistance H may be short-circuited by a special slider.
