Title: Improvements in or relating to alternating current commutator motors
IPC: H02K27/02
Filed: 1927-11-29
Abstract: 306,841. Schwarz, B. Nov. 29, 1926, [Convention date]. Divided on 281,344. Alternating-current motors; windings. - An alternating-current commutator motor has the secondary winding in two parts lying in separate sets so as to have different inductances and the coils of the two windings are connected in parallel to a commutator. The winding S is arranged in slots near the surface of the rotor and the winding S<1>, is in deeper slots. The coils of the two windings are connected together and to a commutator K, but the connected coils are displaced circumferentially by an angle which depends on the relationship of the rotor currents and on the purpose in view. The motor is started as an induction motor as described in Specification 281,344, after which the switch s is closed and alternating current is fed to the commutator from an auxiliary stator winding H whereby the speed or power factor or both may be controlled. Instead of the auxiliary winding H, a transformer may be employed and a resistance r<1> which is cut out gradually may be used to increase the starting torque.

[Class 38 (iv)] Oscillation frequency.-A variably controlled element, such as an inductor 15, adapted to adjust the frequency of an oscillator, such as a tube 1 with tank circuit 12, 13, is subject to a comparison of the phases between the voltage across a crystal 20, and leading and lagging voltages in paths comprising respectively a condenser 21 and an inductor which, together with the crystal, are subjected to the oscillator frequency. As shown in Fig. 1, the comparison is made in pentodes 3, 4 having their screen grids connected to the lagging and leading voltages respectively and their control grids connected to the crystals. Current changes in the tubes 3, 4, due to a change of frequency, control the potentials on the screen grid and control grid respectively of a tube 2 in series with the inductor 15 to correct the oscillator frequency. Fig. 2 shows a crystal 44, condenser 43 and inductor 45 associated with a double rectifier 33, whereby the normal balance in the rectified currents is disturbed by a change in frequency and the charge on a condenser 46 is varied accordingly to vary the impedance of a tube 32 coupling the inductor 47 to the circuit of the oscillator 31.

Abstract: 582,739. Washing-machines. TOMLIN, W. E. April 17, 1945, No. 7059/44. [Class 138 (ii)] The pressure and suction sides of a centrifugal pump f are periodically reversed as between openings n in the cover of the washing container a, and -conduits j extending to the bottom, . so that air is alternately bubbled through the washing liquid and applied under pressure to its surface. In this way, articles lifted out of the liquid during bubbling periods are submerged again in the intervals. Reversal of the pump connections is effected by a rotary valve o driven through reduction gearing s from the pump motor d. The rotary valve body o is divided by a diaphragm q into an upper, pressure section housing the pump rotor f, and a lower suction section communicating with the pump rotor by an opening r. The pressure section has a single port t which registers successively with three fixed ports h each leading to a conduit j, three ports u in the suction section registering simultaneously with fixed ports m leading to three openings n at the top of the container. The ports are shown in development in Figs. 3 and 4 where it will be seen that the ports h have extensions v interposed between the ports m, whilst the ports m have extensions w interposed between the ports h. These extensions reverse the connections of the pump as between the openings n and conduits j in the intervals between the bubbling periods provided by the ports hand m.
