    • A clock design incorporates both digital and analog aspects. An "hour" ball riding a vertically oriented spiral raceway is lifted in a straight line from the bottom of the outer spiral to the bottom of the inner spiral as the raceway rotates at the rate of one revolution per hour, its presence on a given spiral constituting a digital selection of the hour associated with that given spiral. A "minute" ball is fixedly mounted on the raceway periphery, its rotational orientation constituting an analog selection of the minutes.
    • 时钟设计融合了数字和模拟方面。 随着轨道以每小时一转的速度旋转,在垂直方向的螺旋滚道上的“小时”球从外螺旋的底部直线向内螺旋的底部提升,其在给定的螺旋上的存在 构成与给定螺旋相关联的小时数字选择。 一个“分钟”球固定地安装在滚道周边,其旋转方向构成分钟的模拟选择。

    • An artificial sundial formed of a rotatable motor having a shaft which extends through a planar translucent member. A time indicator is positioned adjacent the inner surface of the planar member and is rotatable with the motor shaft. A shadow effect member is secured to the motor shaft and has a portion positioned adjacent the outer surface of the planar member. The time indicator and the shadow effect member rotate in unison with the shaft and produce a visual indication of time.
    • 由可转动马达形成的人造日motor具有延伸穿过平面半透明构件的轴。 时间指示器位于平面构件的内表面附近并且可与电动机轴一起旋转。 阴影效应构件被固定到电动机轴上并且具有邻近平面构件的外表面定位的部分。 时间指示器和阴影效果部件与轴一致地旋转并产生视觉指示时间。

    • A device comprising a mask plate having formed therein at least one symbol indication window comprising at least one relatively narrow and elongated quadrilateral slot or slit and having an inclined base line, a symbol indicator having at least one series of symbol patterns printed or otherwise superposed thereon, and symbol indicator drive means. The symbol indicator drive means intermittently drives and moves the symbol indicator in such manner that the latter is moved a distance corresponding to one half the length of each symbol pattern each time it is driven, whereby one symbol after another can be indicated through the symbol indication window.
    • 一种包括掩模板的装置,其中形成有至少一个符号指示窗口,该至少一个符号指示窗口包括至少一个相对狭窄和细长的四边形槽或狭缝并具有倾斜的基线,符号指示器,其具有印刷或以其它方式重叠的至少一系列符号图案 和符号指示器驱动装置。 符号指示器驱动装置间歇地驱动并移动符号指示符,使得后者被移动到每次符号图案的每半个长度对应的距离,每次被驱动时,可以通过符号指示来指示一个接一个的符号 窗口。
