摘要： A sundial with a concave hemispherical body and top surface generally horizontal has longitude displacement, latitude, sun declination, and time indicia originating at the spherical gnomon located at the spherical center of the hemisphere. Site set up is accomplished by plumbing the gnomon over the site latitude and longitude displacement indicia and then rotating on a horizontal surface until the correct time is indicated by the shadow of the gnomon from the sun. Two six-month sundials or two removably attachable inserts are used for indication of watch time for complete years.

摘要： A typical plate and gnomon sundial with an enlarged dial plate and an extended gnomon is provided with latitude and longitude displacement indicia lines on the dial plate, beneath the gnomon and beyond the time indicia. A point is established on the gnomon from which a plumb line to the latitude and longitude displacement indicia lines can be determined. The latitude and longitude displacement indicia lines are placed so that when a plumb line from the point on the gnomon intersects the point of intersection of the site latitude indicium line with the site longitude displacement indicium line, the gnomon will be inclined to the horizontal at an angle equal to the latitude of the site and the plane(s) containing the gnomon and the 12 o'clock noon indicium line(s) will be inclined to a vertical plane containing the gnomon at an angle equal to the difference between the longitude of the site and the longitude of the time zone meridian.Set up is accomplished at the site by plumbing from the point on the gnomon to the point of intersection of the site latitude and site longitude displacement indicia lines, and while holding this attitude rotating the sundial on a horizontal surface until the correct zone time is indicated by the shadow of the gnomon from the sun on the time indicia. This will mean that the sundial is correctly oriented and will continue to indicate correct zone time.
摘要翻译：典型的板和日式日ial具有放大的表盘和延伸的侏儒，在表盘下方，在牛津以下，超出时间标记，提供了纬度和经度的位移标记线。一个点是建立在从可以确定铅垂线到纬度和经度位移标记线的gnomon上。纬度和经度位移标记线被放置成使得当距离点处的铅垂线与位置纬度标记线与现场经度位移标记线的交点相交时，公园将在水平方向倾斜角度等于场地的纬度，并且包含侏儒和12点中午标记线的平面将倾斜于包含侏儒的垂直平面，角度等于经度时区经线的经度和经度。在现场通过管道从现场点到现场纬度和经度位移标记线的交点，在现场完成设置，同时保持这种态度使日attitude在水平表面上旋转，直到指示正确的区域时间在阳光下的时候，霓虹灯的阴影被标记。这意味着日is正确定向，并将继续指示正确的区域时间。

摘要： A universal sundial which indicates watch time is constructed from a standard pipe section or cylinder with one end an elliptical plane at an angle to the axis of the cylinder preferably within approximately 15.degree. of the latitude of the proposed site. The gnomon is a small sphere located at the center of the elliptical plane end. Time, sun declination, latitude, and meridian displacement indicia are all located on the inner surface of the cylinder by angular coordinates from the center of the gnomon. Two cylinder or two removably attachable overlays are required for indication of civil time for a full year. The sundial is set up by orienting it so the shadow of the gnomon indicates the correct time when the gnomon is in a vertical position over the site latitude and meridian or meridian displacement indicia.
摘要翻译：表示观察时间的通用日is由标准管段或气缸构成，其一端为与气缸轴线成一定角度的椭圆平面，优选地在拟建现场纬度的大约15°内。侏儒是位于椭圆平面末端中心的小球体。时间，太阳赤纬，纬度和子午线位移标记都位于圆柱体的内表面上，角度坐标是从侏儒中心。需要两个圆柱体或两个可拆卸的可覆盖的覆盖层，用于指示全年的民用时间。日is是通过定向来设定的，因此，当牛津在纬度和子午线或子午线位移标记的位置处于垂直位置时，该公式的阴影表示正确的时间。
