Abstract: The present invention provides an LED signal light device comprising a central processing unit, a control panel, an LED signal light, an output and input interface, a battery and an adapter. The central processing unit comprises a microprocessor, a memory and an interface circuit for controlling the operation of the whole device, and outputting a signal and receiving a command through the output and input interface. The control panel is a printed circuit board recorded a circuit therein. The LED signal light consists of plural LEDs, which are three coloring LEDs or color changing LEDs. The LEDs actively show a light display in a closed circuit and show various colors accompanying with various arrangements into abstract symbols for indicating various traffic situations. The device can be connected to an AC power supply of 110 V or 220 V, and the AC power is converted to DC power by an adapter, which also stabilizes the current provided to the whole device. The battery alternatively is provides power to the whole device with its storage power when the power source is ineffective.

Abstract: The present invention relates to a method for treating spent tin or tin/lead stripping solution used in the electronic industry, particularly in the manufacture of printed circuit boards or a lead frames. Said method comprises (i) electrolytically reducing copper ions in the solution to copper at a low temperature; (ii) electrolytically oxidizing Sn2+ and Pb2+ in the solution at a high temperature to form solid tin and lead oxides and hydroxides; (iii) separating solid tin and lead oxides and hydroxides from the solution; (iv) dissolving tin and lead oxides and hydroxides obtained in step (iii) in a strong alkali or acidic solution; and (v) electrolytically reducing the alkali or acidic solution obtained in step (iv) at a high temperature to recover metallic tin and lead. Also, the filtrate obtained in step (iii) above is useful for preparing fresh tin or tin/lead stripping solution.

Abstract: A bath scrubber mainly includes a front nylon piece and a back piece that are sewed up to form a bag defining a unitary inner space for accommodating a plurality of massage balls therein. Restricting means are provided on the back piece and the front nylon piece at positions between any four adjacent massage balls. The restricting means divide the unitary inner space defined by the bag of the bath scrubber into several smaller spaces that each confines a massage ball therein but allows the massage ball to freely and smoothly rotate when the bath scrubber is moved on a user's skin to and fro for cleansing purpose. The bath scrubber with massage balls restricted in separated small spaces can therefore not only hold more bubbles to achieve enhanced cleaning effect but also provide good massage effect.
