    Abstract: A back cleaning brush mainly including two steel wires and a large number of mixed brush hairs, foam rubber strips and/or scouring pads positioned between the two steel wires. The steel wires are spirally twisted together to tightly clamp the brush hairs, the foam rubber strips and/or the scouring pads in place, so that two ends of the brush hairs, the foam rubber strips, and/or the scouring pads evenly and radially extend outward from the twisted steel wires. The foam rubber strips and the scouring pads have good water absorbing ability to hold sufficient amount of water and soap bubbles when the back cleaning brush is wetted to clean user's back.

    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.
