Title: Improvements in Apparatus for Converting Multiphase Current into Continuous Current.
Filed: 1905-01-07
Granted: 1906-02-07
Abstract: 343. Bruce, Peebles, & Co., and La Cour, J. L. Jan. 7. Converting alternating and direct currents.-Relates to apparatus for converting multiphase current into continuous current, and consists of two stationary transformers, of which the primaries P', P<3>, P<5> of one are star-connected and the primaries P<2>, P<4>, P<6> of the other are meshconnected, and the secondaries S' ... S<6> connected in series to form a closed winding, the points of connexion of the secondaries being connected to a stationary commutator K, from which continuous current is taken by brushes b rotated by a synchronous motor or otherwise. The commutator may have a multipolar construction, in which case the commutator bars separated by twice a pole pitch are connected together. To suppress the higher harmonic fields and the stray fields, which arise at the moment of commutation, the transformers are provided with two compensating- windings A' &c., B' &c. connected together as shown, the compensating-windings acting as short-circuited coils in respect of all the higher fields excepting the (12<n> + 1)th harmonics. The fundamental field and the (12<n> + 1)th harmonic fields induce electromotive forces in the compensating-windings, which differ in phase by ninety degrees, so that a two-phase synchronous motor adapted to rotate the brushes may be supplied with current from the compensating-windings. If it is desired to obtain a high-tension continuous current, the secondaries S<1> . . . S<6> may be arranged as described in Specification No. 28,416, A.D. 1904, [Abridgment Class Electricity, Measuring &c.].

Granted: 1907-11-21
Abstract: 5565. Mershon, R. D. March 7. Motors, controlling.-To improve the operation of single - phase induction motors, condensers C, Fig. 1, are connected across points of the primary windings P, and to render the motor selfstarting, one or more reactances R are connected to the primary windings at points less than ninety electrical degrees from the supply leads l, l<1>, for producing a rotary field. The reactances R may be cut out at synchronism by opening a switch s. Several condensers may be employed, connected across equidistant points of the primary winding, this arrangement being of particular advantage in the ease of a motor having a variable number of poles. In Fig. 4, the primary winding P is adapted for connexion for eight, four, and two poles through a controller C<1>, and the condensers c are arranged in two groups, one group being connected across the leads l<3> to l<9> corresponding to the greatest number of poles, while the other group is connected across points situated ninety electrical degrees from those leads. In general, the spacing of the condenser terminals is not greater than the pole-pitch. In the first position of the controller, the motor is connected for eight poles, and a reactance R is connected with points on the primary winding P situated less than ninety electrical degrees from the supply leads. The reactance R is cut out in the second position of the controller, the third and fourth positions connecting the motor for four and two poles respectively. To improve the starting-torque and power factor, the sections of the rotor winding are shunted by impedances f and capacities e arranged in parallel, with or without the addition of resistances d, as described in Specification No. 8183, A.D. 1907. At synchronous speeds, the devices practically neutralize one another.

Granted: 1907-07-04
Abstract: 5669. Bucherer, M. March 8. Revolving-cylinder type.-Fig. 1 shows the type of explosion engine to which the invention relates. The cylinders e,f are mounted on a hollow shaft g, and the rod of the reciprocating pistons is connected by a crank l to the shaft d, which is out of alinement with the former shaft by a distance equal to the length of the crank. The objects are to maintain the relative positions of the piston-rod and crank when the engine is stopped with the crank-pin opposite the centre of the shaft g, and to reduce bending stresses in the piston-rod due to pressure of the pistons on the cylinder walls. A pinion b is fitted to the shaft d, and gears with an annular wheel a having twice the number of teeth. This wheel a is rigidly fixed to the revolving cylinders, and the gearing completely constrains the motion and absorbs irregular pressures. Four cylinders may be used, the second pair being at right-angles to the first and displaced a short distance axially, their crank being opposite to the crank l. Power may be taken from either or both the pulleys h, k,
