    • Disclosed is a device for boring holes in ice having a vertical boring position and a horizontal carrying position. The device is comprised of a drive unit with an output, a rotatable shank portion and auger portion coupled to the output. A non-driven grasping portion is connected to the drive unit and configured such that the device has a balance point at the grasping portion whereby the device may be carried in a balanced horizontal position with one hand. In a preferred embodiment a hollow cylindrical portion with a flange attaches to the drive unit and the shank portion extends through the cylindrical portion and is coupled to the out in the cylindrical portion. The grasping portion may either be the cylindrical portion or a separate bar portion attached to the cylindrical portions.
    • 公开了一种用于在具有垂直钻孔位置和水平承载位置的镗孔中钻孔的装置。 该装置包括具有输出的驱动单元,可旋转的柄部分和联接到输出的螺旋部分。 非驱动把持部分连接到驱动单元并且被构造成使得该装置在抓握部分处具有平衡点,由此该装置可以用一只手承载在平衡的水平位置。 在优选实施例中,具有凸缘的中空圆柱形部分连接到驱动单元,并且柄部分延伸穿过圆柱形部分并且联接到圆柱形部分中的出口。 抓握部分可以是圆柱形部分或附接到圆柱形部分的单独的杆部分。

    • A control for a window operator is operable to control incremental movement of a window. The control includes means for developing a command to selectively move the window in a direction to an open or closed position, and means for determining when a plurality of motor drives have moved the window a preselected incremental distance. Means are coupled to the developing means and the determining means for energizing each of the motor drives if a command is developed, until the motor drives have moved the window the preselected incremental distance and thereafter deenergizing the motor drives until another command is received to move the window a subsequent incremental distance in the selected direction.
    • 窗口操作器的控制可操作以控制窗口的增量移动。 该控制器包括用于开发用于选择性地将窗口沿一个方向移动到打开或关闭位置的命令的装置,以及用于确定多个电动机驱动器什么时候将窗口移动到预选的增量距离的装置。 装置耦合到显影装置和确定装置,用于在显影指令时对每个电动机驱动器通电,直到电动机驱动器将窗口移动到预选的增量距离,然后使电机驱动器通电直到另一个指令被移动 窗口中所选方向的后续增量距离。
