摘要： A drafting machine head in accordance with this invention is provided with a rotatable drawing ruler carrier whose angular position on a graduated circle is incrementally detected by means of scanning elements and is converted into displayable angular valves by an up/down counter, and with one or several electronic data stores, characterized in that it contains an electrically actuable locking unit (10, 11) for the rotary movement of the drawing ruler carrier (13), which unit is active in any angular position and is connected through an electronic comparator (25) to the data store or stores (23) in such a way that the valves detected on the graduated circle (12) and the valves contained in the data store (23) trigger the locking if they are in coincidence.By this means a drafting machine head is provided which can be set to a higher degree of accuracy and is less subject to wear than is known from the prior art.

摘要： A light emitting diode is located beneath a glass scale carrier, one for each scale (azimuth and elevation), emitting essentially monochromatic light, which penetrates through the glass scale; the scale is observed through an optical system. The optical system for viewing of the scale is located on a carrier secured in the telescope housing; the light emitting diodes are powered by a battery secured in the housing, which energizes a timer, such as R/C circuit settable for normal observation times, for example about thirty seconds.
摘要翻译：发光二极管位于玻璃刻度载体下面，每个刻度（方位角和仰角）一个，发射基本上单色的光，其穿透玻璃鳞片; 通过光学系统观察刻度。用于观察标尺的光学系统位于固定在望远镜壳体中的载体上; 发光二极管由固定在壳体中的电池供电，其为定时器（例如可设置用于正常观察时间的R / C电路）通电，例如约30秒。
