Title: Hydrogen storage electrode and manufacture thereof
Inventor: SHIRAIWA SHINYA
IPC: H01M4/62
Filed: 1993-08-02
Abstract: PURPOSE:To improve a cycle life by containing a water soluble high molecule and rubber resin in a binding agent of holding hydrogen storage alloy powder in an electrode, so as to prevent the hydrogen storage alloy powder from coming off from the electrode.

Title: Purification of gallium solution
Inventor: ARAN RUBEEKU
IPC: C22B3/00
Filed: 1981-12-02
Abstract: Highly pure (>99.99%) aqueous solutions of gallium chloride are obtained by a process having two major stages. The first stage, effected by passage of an aqueous acid solution containing gallium over a strongly basic ion exchange resin, makes it possible to eliminate an appreciable quantity of metal ions, such as Ca, Mg, Cr, V, Co, Zn and Pb, and further serves to concentrate the initial solution. In the second stage, the remaining ions, such as Al, Na and particularly Fe+++ are eliminated by a two-phase extraction with an organic extractant, preferably a C4 to C10 alcohol or a quaternary ammonium chloride.
