    摘要： A fail-safe solenoid switching mechanism (11) uses a reciprocating switch (15) to establish make-or-break connections. In order to increase the effective life of shorting bars on the switch, the switch's reciprocating part 23 is rotated by a ratcheting mechanism each time the switch (15) is cycled.Advantages include enhanced reliability, even when the switching mechanism (11) sees extended quiescant periods between operations.

    摘要： A fail-safe solenoid switching mechanism (11) includes separate solenoids (17,18) for switchings to "armed" and "safed" statuses. A manually operated safing mechanism (19) has a capability of overriding the solenoids (17,18) to establish the switching mechanism (11) in the "safed" status. The manually operated safing mechanism (19) is operated by a special tool (41), which is retained by the switching mechanism (11) whenever the manually operated safing mechanism (19) is engaged. The manually operated safing mechanism (19) is held in engagement by a catch (22) whenever the solenoid (17) for arming is powered, thereby preventing the specialized tool from being removed and the switching mechanism (11) from inadvertently switching to the "armed" status. Further status indications are provided by a flag (54) which can be used to directly read the status of the switching assembly (11).The switching assembly (11) uses a reciprocating switch (15) to establish make-or-break connections. In order to increase the effective life of shorting bars on the reciprocating part of the switch, the reciprocating part is rotated by a ratcheting mechanism each time the switch (15) is cycled.Advantages include enhanced reliability, and positive assurances as to the operating status of the switching assembly.

    摘要翻译： 一个故障安全电磁开关机构（11）包括用于切换到“挂起”和“安全”状态的单独螺线管（17,18）。 手动操作的安全机构（19）具有超越螺线管（17,18）的能力，以建立处于“安全”状态的切换机构（11）。 手动操作的安全机构（19）由专用工具（41）操作，每当手动操作的安全机构（19）接合时，其由切换机构（11）保持。 每当用于布防的螺线管（17）被供电时，手动操作的安全机构（19）由卡扣（22）保持接合，从而防止专用工具被移除，并且切换机构（11）不经意地切换到“ 武装“地位。 通过可用于直接读取开关组件（11）的状态的标志（54）来提供进一步的状态指示。 切换组件（11）使用往复式开关（15）来建立断开或断开连接。 为了增加开关的往复运动部件上的短路棒的有效寿命，每当开关（15）循环时，往复运动部分由棘轮机构转动。 优点包括提高可靠性，以及对开关组件的运行状态的积极保证。

    摘要： A three-position actuating mechanism (10) for a transfer switch (11) is disclosed. The transfer switch is movable by the actuator (10) between a contact block (13) corresponding to a normal power source, and a contact block (14) interconnected to a standby or emergency power source. The actuator (10) has a pair of disk drives (22, 23) interconnected to solenoids (20, 21) by means of linkages (33, 34). The disk drives (22, 23) are interconnected to each other and to a driven disk (26) by means of a pin (30). Energization of the solenoids (20, 21) causes movement of the corresponding solenoid plunger (31, 32) and rotation of the disk drives (22, 23), so as to cause rotation of the contact crossbar (16) and transfer of the contacts (15, 18) between the two power sources.

    摘要： 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.
