Title: Improvements in polyphase commutator machines
IPC: H02K27/12
Filed: 1925-03-16
Abstract: 233,667. Heyland, A. H. May 12, 1924. [Convention date]. Alternating-current commutator machines; windings; exciting.-The stator windings of polyphase commutator machines are wound with a mean resultant pitch which its less than a normal full pitch winding and less than the rotor winding, a field being thereby superposed on the main field having the phase of a commutating- field at the phase axes and, with brushes shortcircuited, an exciting field between the phase axes. Fig. 2 shows diagrammatically a normal ampere-turn distribution, and Fig. 3 the principle underlying the distribution according to the invention for a three-phase stator. Each phase winding is divided into two portions a<1>, a<11> - -, the portions a<1>, c<11> on opposite sides of phase axes being oppositely wound. Resultant currents in these portions produce a field which is in advance of the main field at phase axes and behind it at points between these axes, the additional negative field component between the axes being indicated at n<1>. Fig. 6 shows a winding diagram in which the portions a<1>, c<11> comprise three short-pitch coils per phase, the mean winding pitch being 0.5 ordinary pitch. To reduce the component n<1>, i.e. to make it less negative, the inner turns in Fig. 6 are replaced, for example, by overlapping turns d, Fig. 7, the mean winding pitch then being 0.72 ordinary pitch. The overlapping turns of adjacent phases may be wound in the same or in neighbouring slots, or, a, shown in Figs. 9 and 10, they may cross in some slots and not in others, the mean winding pitch in Figs. 9 and 10 being 0.75 ordinary pitch. One phase is indicated on the Figures by arrows connecting the coils together. The arrangement shown in Fig. 10 is adapted for six-phase working with diametrically opposite coils connected, the mean winding pitch in this case being 0.5 ordinary pitch. The additional field components may be increased by winding the stator phases in a single slot per phase. Other arrangements are described, and in all cases the ampere-turns of the short-pitch coils cover at least one-third of the stator circumferential measured in slots.

IPC: D01D7/00
Filed: 1929-03-05
Abstract: 307,357. Sondermann & Co. March 5, 1928, [Convention date]. Reeling machines. -Freshly s p u n threads of artificial silk from the spinning bath are reeled without doubling in close set, quicktraverse turns free from gaps and preferably in thick layers. The resulting compact cheeses are removed from the reeling device with- 'out being tied and are subjected to treatment with liquids. The threads, instead of being wound in the normal manner as shown in Fig. 2, with gaps o for intertwining the skein threads d, are wound on rollers or reels of roller type provided with particularly broad supporting surfaces a, Fig. 1, in quick-traverse compactly disposed turns b. The threads may be wound on single reels or several threads separated by intermediate spaces may be wound on longer reels or rollers. Pervious backings such as felt, fabric or wire gauze may be applied to the reels and taken off with the cheeses of yarn, which can easily be removed without being tied in skeins, for example, by reducing the peripheral dimensions of the reel. The cheeses offer considerable resistance to damage of the threads owing to their compact winding and the thicker layer of threads assures increased length between knots and therefore fewer interruptions in the spinning process, necessitated by changing the reeling appliances. The cheeses are then treated with liquids. The cheeses may be drained in a centrifuge but they may be dried directly by transferring the frames to the drying apparatus. Cheeses treated in the manner described can be unwound very quickly, when placed on suitable apparatus such as drums, winding crowns or plates, in either a lateral or radially inward direction, and may be subjected to any further process, such as doubling, during the unwinding operation.
