摘要： A digital clock or other counting device in which the output shaft on the drive motor of the device is resiliently connected to the gear train by means of a spiral spring. The drive motor is of the stepper motor type and applies energy to the spring in discrete increments. During the initial portion of each increment, the gear train remains stationary, and it then gradually accelerates and continues its movement after the motor shaft has come to rest. The arrangement is such that there is a very smooth and quiet transfer of energy from the shaft through the gear train to the individual counting elements. In some embodiments the counting elements comprise register drums in which motion is transferred between certain of the drums by a Geneva type transfer pinion assembly and between other drums by resiliently biased planetary gearing.
摘要翻译：数字时钟或其他计数装置，其中装置的驱动电动机上的输出轴通过螺旋弹簧弹性地连接到齿轮系。驱动电机是步进电机类型，并以离散增量向弹簧施加能量。在每个增量的初始部分期间，齿轮系保持静止，然后在电动机轴静止之后逐渐加速并继续其运动。这种布置使得能量从轴通过齿轮系到各个计数元件非常平滑和安静地传递。在一些实施例中，计数元件包括定位鼓，其中运动通过日内瓦型传递小齿轮组件在某些滚筒之间并且通过弹性偏置的行星齿轮传动在其它滚筒之间。

摘要： Apparatus for setting the hour hand of a clock one hour ahead at the beginning of daylight saving time or one hour back at the end of daylight saving time by moving two gears that are connected together and are meshed, respectively, with a gear on the shaft that drives the minute hand and a separate gear on the concentric shaft that drives the hour hand. The pair of gears is mounted on a support that may be pivoted about the same axis as the minute and hour hands by moving the support mechanically or through the interaction of a magnetic member on the support and a magnetic controller.

摘要： A small, round synchronous motor including a permanent magnet rotor and only a single salient stator pole in magnetic flux relationship with the rotor. Upon the energization of the field coil for the motor, at any given moment the stator pole is of one polarity. When the field coil is de-energized, the rotor consistently assumes a position with respect to the stator pole in which the rotor poles are displaced from the center of the stator pole so that, when the coil is again energized, the rotor is self-starting.

摘要： A clock mechanism driven by a pulsed stepper motor and having planetary reduction gearing which provides a continuous but resilient connection between the motor and the minute hand of the clock at all times. The motor includes a permanent magnet rotor in direct driving relationship with the minute hand, and the rotor poles serve as a magnetic detent to hold the minute hand in discrete angular positions. The mechanism may be employed either in individual clocks or in the secondary clocks of a mastersecondary clock system. In these latter embodiments the secondary clocks additionally include a pair of switches respectively controlled by the minute hand gearing and the hour hand gearing. The switches greatly facilitate the automatic resetting of the clocks in response to appropriate resetting signals from the master unit.

摘要： A heat dissipating circuit board assembly includes a heat sink having a first wall, a second wall spaced from the first wall, and an end wall extending between the first and second walls. The first wall, the second wall, and the end wall collectively define a cavity. The assembly additionally includes a printed circuit board having a first face and a second face opposite the first face. The printed circuit board is located within the cavity such that the first wall of the heat sink extends over the first face and the second wall of the heat sink extends over the second face to allow heat to be transferred from the printed circuit board to the heat sink. The heat sink is configured to interface with a connector socket when the circuit board is connected to the connector socket for stabilizing the printed circuit board.
