摘要： An automatic power reduction circuit having a single silicon controlled rectifier in one leg of a bridge rectifier which is gated off when a capacitor reaches a predetermined voltage level so as to switch automatically the bridge output from a full-wave rectifier to a half-wave rectifier. An auxiliary silicon controlled rectifier is also provided to facilitate the quick discharge of the capacitor so as to reset the circuit to its initial state, thereby allowing fast, repeated operations and preventing malfunctioning upon a loss of power.

摘要： An axially polarized bar magnet is slidably disposed in a non-conductive, non-magnetic tube on which two serially connected oppositely wound induction coils are disposed, the coils being spaced apart by a distance less than the effective length of the magnet.

摘要： One or more LEDs are connected across an induction coil wound on a tube slidably carrying an axially polarized permanent magnet, the tube being closed at both ends so that axial reciprocation of the tube causes the magnet to move back and forth through the coil and energize the LEDs.
摘要翻译： 一个或多个LED连接在缠绕在可滑动地承载轴向极化永磁体的管上的感应线圈上，该管在两端封闭，使得管的轴向往复运动使得磁体通过线圈前后移动， LED。

摘要： The carbon-wax coating is removed from carbon paper by sequentially immersing the coated paper in hot aqueous baths, the paper being squeeze-dried prior to immersion in each bath after the first. Ultrasonic vibrations are applied to the first bath to mutually separate the individual pieces of the paper.
