摘要： A thermostat having a cover plate rotatable about a central horizontal support in which a bimetal or other thermally responsive member supported on the cover plate actuates a mercury switch also on the cover plate. This cover plate also has upon it indicia such as degree marks or simply arrows indicating "colder -- warmer" operable against an imaginary vertical lubber line to indicate a setting. The need for time consuming and expensive levelling of the thermostat during installation is thus obviated because the thermostat is automatically levelled by the user as a result of setting the indicia in relation to the imaginary vertical line.
摘要翻译：一种恒温器，其具有围绕中心水平支撑件旋转的盖板，其中支撑在盖板上的双金属或其他热响应构件也在盖板上起动水银开关。该盖板还具有标记，诸如度数标记或简单的箭头，指示“较冷 - 更暖”，可操作于假想的垂直橡皮筋线以指示设置。因此，在安装期间，需要耗费时间和昂贵的调温器的调平，因为由于通过将标记设置成相对于虚拟垂直线而使恒温器自动调平。

摘要： An aircraft instrumentation having inherent self-checking features. Radar and barometric altitude information are displayed on the dial face of a single instrument. A cooperating dial and first pointer displays barometric altitude. A manually settable indicator "bug" cooperates with the dial to provide a presentation of the height of the airstrip relative to sea level. A second indicator "bug" of a different shape from the landing field bug is servo-driven from both radar and barometric altitude signal inputs to provide a presentation of aircraft altitude relative to the terrain beneath the aircraft. The angle between the barometric altitude pointer and servoed radar altitude "bug," measured counterclockwise, constitutes the distance of the aircraft above the airstrip or other terrain which the aircraft is passing over. Upon touchdown both "bugs" should be in exact coincidence, thereby serving as a self-check upon accuracy of the instrumentation.
摘要翻译：具有固有自检功能的飞机仪表。雷达和气压高度信息显示在单个仪器的刻度盘上。合作表盘和第一个指针显示气压高度。手动可设置的指示器“错误”与表盘配合以提供相对于海平面的机场高度的呈现。与着陆场错误不同形状的第二个指标“错误”是从雷达和大气高度信号输入端伺服驱动的，以提供相对于飞机下方的地形的飞机高度呈现。逆时针测量的气压高度指示器和伺服雷达高度“bug”之间的角度构成飞机在飞机跑道上方的飞机跑道或其他地形之间的距离。触地后，“错误”应该是准确的巧合，从而作为仪器准确性的自我检查。
