摘要： A laser level includes a level-adjusting device and a laser transmitter device mounted on the level-adjusting device. The level-adjusting device includes a horizontal flat board movable by a plurality of motor modules to a desired condition, a cross rotatable circle including an outer circle rotatable about a first rotation axis and a concentric inner circle rotatable about a second rotation axis perpendicular to the first rotation axis, and a connecting post connecting the horizontal flat board to the cross rotatable circle and supporting the laser transmitter thereon.

摘要： An automatic plumb, level and pointing tool uses a visible laser diode to project light beams in two modes through two windows. In the first mode of operation, the unit is able to project a plumb-up beam and a level beam of light while resting on a surface which is as much as five degrees out of level. In the second mode of operation the unit is able to project two orthogonal beams of light both approximately in the horizontal plane for aligning one or more reference lines. An accurate, low cost method of generating level and plumb beams and planes of light is disclosed. One method uses an approximately leveled platform combined with a weak optical correction. The approximate leveling is done using a single wire or coil spring pendulum element which allows the platform to level itself to within a small fraction of true level, and remaining correction is provided by a weak negative lens or a weak reverse telescope. In alternative embodiments, all leveling is accomplished using a very flexible coil spring as a pendulum element, or a chain link connection in combination with such a spring. Several accessories are disclosed for use with the laser tool.
摘要翻译：自动铅垂，水平和指向工具使用可见激光二极管通过两个窗口以两种模式投射光束。在第一种操作模式下，该单元能够在搁置在多达五度的水平面的情况下投射铅垂梁和水平光束。在第二操作模式中，该单元能够投射大致在水平面中的两个正交光束，用于对准一个或多个参考线。公开了一种产生水平和垂直射束和光平面的精确，低成本的方法。一种方法使用与弱光学校正相结合的近似平坦的平台。使用单线或螺旋弹簧摆元件进行近似的调平，该摆线元件允许平台将其自身调整到真实水平的一小部分内，并且由弱负透镜或弱反向望远镜提供剩余校正。在替代实施例中，使用非常灵活的螺旋弹簧作为摆锤元件或与这种弹簧组合的链节连接来实现所有的整平。公开了与激光工具一起使用的几个附件。

摘要： A laser beam levelling instrument has a pipe length which is vertically and centrally mounted in the cover of a casing. The ends of this pipe length are pivotable, so that it can always be held in the vertical position. For this purpose two spirit levels are arranged at right angles to one another on a plate fixed to the lower end of the pipe length. The fluid in these levels is electrically conducting and the levels have electric contact points for operating a respective electric motor. The electric motors are provided with eccentric shafts which come into contact with the circumferential surface of the pipe length. If the pipe length diverges from the vertical, then the current from batteries ensures that it is brought back into the vertical position by means of the eccentric shafts. A laser light source is located in the lower part of the pipe length and a further pipe length is inserted in the upper end of the pipe length and can be rotated by a third electric motor. The further pipe length carries a head with a window. The laser beam enters the head vertically, is diverted there into the horizontal and passes out of the window as a horizontal laser beam.
摘要翻译：激光束矫平器具有垂直和中心地安装在壳体的盖中的管道长度。该管道长度的端部是可枢转的，因此它总能保持在垂直位置。为此，在固定在管道长度的下端的板上，两个水平线彼此成直角。这些级别的流体是导电的，并且电平具有用于操作相应电动机的电接触点。电动机设有与管道长度的圆周面接触的偏心轴。如果管道长度从垂直方向发散，则电池的电流确保通过偏心轴将其回到垂直位置。激光源位于管道长度的下部，另外管道长度插入管道长度的上端，并可由第三电动机旋转。另外的管道长度带有带窗口的头部。激光束垂直进入头部，被转移到水平面并作为水平激光束从窗户中流出。

摘要： A self-leveling instrument mount comprises an instrument table pivotally mounted above a stationary frame on first, second and third vertical support arms. The first support arm is a fixed length member connected to the frame through a ball and socket joint. The second and third support arms are formed of screws extending between the table and frame having effective lengths that are controlled, respectively, by first and second servo motors in response to a pendulum switch to maintain the table parallel to a horizontal reference plane. The pendulum is magnetically damped during operation of the servo motors for stabilization. A mercury switch on the table disables the servo motors when the tilt of the table is too large to be leveled by the support screws.
