    Abstract: A common coil device in a dryer control circuit usable as an electromagnetic device for developing functions of both a motor and a relay. The relay function is utilized as a circuit continuity function which is normally provided as a shunt to a momentarily operated starting push button, and the motor function is utilized as a timer for intermittent pulsing of the dryer drive motor during an antiwrinkle cycle.

    Abstract: A fabric treating apparatus, such as a domestic clothes dryer, is provided with a digital control circuit and a sensor system which cooperate to terminate a fabric treatment operation when the fabric has reached a desired condition. A digital counter receives and accumulates pulses from a reference source and is repetitively reset by signals from a sensor circuit which provides reset pulses at a rate dependent upon the dryness condition of the fabric load. As the fabric load approaches the desired dryness condition the interval between reset pulses increases, thus allowing the counter to accumulate successively greater counts before being reset, until eventually a preselected count is accumulated which triggers circuitry to terminate the fabric drying operation. After termination of the drying operation the counter serves as a clock and operates in conjunction with an indexable digital memory and associated logic circuitry to control a program of subsequent fabric treatment operations.

    Abstract translation: 诸如家用干衣机的织物处理设备设置有数字控制电路和传感器系统,当织物达到期望状态时,​​它们协作终止织物处理操作。 数字计数器接收和累积来自参考源的脉冲,并且由来自传感器电路的信号重复地复位,该传感器电路以取决于织物负载的干燥条件的速率提供复位脉冲。 当织物负载接近所需的干燥条件时,复位脉冲之间的间隔增加,从而允许计数器在复位之前逐渐积累更多的计数,直到最终累积预定的计数,触发电路来终止织物干燥操作。 在干燥操作终止之后,计数器用作时钟,并与可转位数字存储器和相关联的逻辑电路结合操作,以控制随后的织物处理操作的程序。
