Abstract: The number of voltage dips of an alternating source of electrical energy of a plurality of separate magnitude are counted in accordance with the method of the invention with the structure of the invention. A reference voltage is produced from the source of electrical energy of substantially the root means square voltage of the source of electrical energy and the reference voltage is compared with each single cycle voltage in separate comparison circuits for each of a number of selected voltage dip magnitudes to provide output signals each time the single cycle voltage dips below the selected magnitudes of the separate comparison circuits and the output signals of each comparison circuit is counted separately. The comparison is accomplished in unijunction transistors which may be compensated for temperature change while the counting is accomplished by counters energized through silicon-controlled rectifiers in series with the counters.

Abstract translation: 根据具有本发明结构的本发明的方法，对多个独立量值的交替的电能源的电压骤降数进行计数。 从电能源的基本电源产生参考电压，并且将参考电压与单独的比较电路中的每个单个周期电压进行比较，所述比较电路针对多个选定的电压下降幅度 每当单个周期电压下降到单独的比较电路的选定幅度以下时，提供输出信号，并分别计算每个比较电路的输出信号。 比较在单结晶体管中完成，可以补偿温度变化，而计数由通过与控制器串联的硅控整流器通电的计数器实现。

Abstract: The disclosure is of a feed wheel assembly for applying a continuous motive force to a train of intermittently movable parts. The feed wheel assembly has a feed ring mounted on a continuously driven clutch ratchet wheel, the latter having alternate crests and recesses along its periphery. Spring-pressed followers on the ring engage the crests and recesses of the clutch ratchet wheel to provide a yieldable drive to the feed ring. The followers are spaced apart different distances than the crests so that when the drive slips, the followers pass over the crests successively rather than simultaneously.
