Title: Recovery of precious metals from acid solutions by electroactive polymers
Inventor: KANG EN-TANG
IPC: C22B11/00
Filed: 1994-09-27
Abstract: The process for the recovery of precious metals from acid solutions by electroactive polymers is spontaneous and self-sustained and enables a precious metal such as gold to be recovered from an acid solution containing the metal in solution. The said acid solution is treated with an electroactive polymer such as polyaniline to cause reduction of the metal in solution to the free metal and allowing the free metal to precipitate from the solution and accumulate as the reduction progresses.

IPC: H04N5/217
Filed: 1998-04-28
Abstract: In a flare correction apparatus to correct flare of a digital image signal including digital red data (R), digital green data (G) and digital blue data (B), each of the R, G and B containing a plurality of horizontal lines (HL's), each HL having predetermined N number of pixels, a RGB-data flare correction circuit 200 performs a flare correction on HL's of the R, G and B on a HL-by-HL in accordance with a predetermined flare correction method to thereby provide flare corrected red, green and blue data (Rc), (Gc) and (Bc), respectively. And then an image signal converting circuit 300 performs an image signal conversion on the Rc, the Gc and the Bc to thereby generate a luminance signal (Y) and a chrominance signal, wherein the Y includes a plurality of horizontal luminance lines (HLL's), each HLL having N number of luminance pixels. Thereafter, a luminance signal flare correction circuit 400 performs a luminance signal flare correction on HLL's of the Y on a HLL-by-HLL basis in accordance with the predetermined flare correction method to thereby supply a flare corrected luminance signal. Therefore, the flare correction apparatus of the present invention can perform flare correction on a digital image signal with less memory capacity and improve the flare correction accuracy over the prior art since the flare correction thereon is performed on a HL-by-HL basis.

Title: Buckle assembly
Inventor: ANSCHER JOSEPH
IPC: A44B11/26
Filed: 1998-06-05
Abstract: A plug and socket-type buckle assembly in which the plug portion comprises a base 27 and flexible plate(s) 21,22 integrally formed therewith. A locking lug 25 extends across the free end of the plate and protrudes both above and below the flat surfaces of the plate. The socket portion comprises a integral top 34 and bottom 33 parts which define a cavity for receiving the plug portion. The top part 34 has an integral flexible release button 31 with a downwardly projecting tip 35. There is at least one projecting ledge 37 disposed on the inside of the top part to engage one side of the inserted locking lug. A flexible tongue 38 is integral with the bottom part 33 and has means 39 for engaging an opposite side of the inserted locking lug. Downward pressure on the release button when the plug portion is inserted in the socket portion disengages the locking lug from the projecting ledge. Further pressure on the release button causes the tip of the release button to engage the flexible tongue at 40 and bend the tongue to release the locking lug to remove the plug portion from the socket portion.
