Title: Improvements in Means for Increasing the Power-factor and Overload-capacity of Alternating Current Asynchronous Machines.
Inventor: KAPP GISBERT
IPC: H02K17/00
Filed: 1911-11-07
Granted: 1912-10-17
Abstract: 24,823. Kapp, G. Nov. 7. [Cognate Application, 741/12.] Alternating-current induction machines; oscillating machines.-To improve the power factor of asynchronous machines, a leading electromotive force is introduced into the secondary circuit and is derived from a machine comprising a fixed and an oscillating electro-magnet or armature, one of which is excited by direct current and the other is traversed by the alternating-current of low frequency circulating in the secondary circuit of the main machine. One form of phase-compensator is shown in Fig. 1, in which the stator S is provided with a ring or drum winding W carrying the slip-current of the main machine and with a winding G<1> fed with direct current and having its magnetic axis perpendicular to that of the winding W. A magnet M, which may be a permanent magnet or may be excited by direct current, is pivoted at the centre O. One of these machines is inserted in each phase between the slip-rings of the main machine and the starting - rheostat. When no alternating current is sent through the winding W, the magnet M takes up a position in line with the magnetic axis of the winding G'. On supplying the slip-current to the winding W, the magnet oscillates through an angle of approximately 90 degrees on either side of its vertical position, thereby inducing an electromotive force in the winding W which is in quadrature with the alternating current causing the vibration. Damping windings D prevent excessive oscillations of the magnet M. The magnitude of the compensating electromotive force may be varied for different loads either by fitting the magnets M with adjustable balance weights, or by varying the direct-current excitation either by hand or automatically; a resistance in the direct-current circuit may be varied by means of a solenoid inserted in the primary or secondary circuit of the main machine. The oscillating machine may be built like a direct-current motor, the direct-current windings G, Fig. 3, being arranged on the fieldmagnet poles, while the slip - current is sent through the armature by means of a commutator and brushes B; or the commutator may be dispensed with, the alternating - current being passed into the armature by flexible cables. Commutating poles C<1>, C<2> may be provided. To prevent unequal wearing of the commutator, the armature may be caused to move round very slowly, for instance by providing the fieldmagnet with a few turns through which the alternating-current is led. The stator magnets of several machines may be combined into one magnetic frame.

Granted: 1912-07-04
Abstract: 25,166. Hoffmann-La Roche & Co., F. Jan. 25, [Convention date]. Cresols and their sulphonic acids.-In a process for the separation of m- and p-cresols, the cresol mixture is sulphonated with less than, or with approximately the theoretical, quantity of sulphuric acid for the formation of the monosulphonic acids, at a temperature below 100‹ C., with or without the addition of a solvent for the p-cresol.
