Abstract: An artist's brush washing apparatus providing multiple washings of an artist's brush utilizing fresh solvent and facilities for holding contaminated solvent. A top unit includes a washing basin which receives fresh solvent from a solvent reservoir assembly. The top unit overlies a holding pan and a solvent flushing assembly provides for the control and removal of contaminated solvent from the washing basin into the pan and the introduction of fresh solvent into the washing basin from the solvent reservoir assembly.

Abstract: An electrolyzer for the generation of hydrogen gas having parallel electrodes comprising a single cell with multiple cells connected in a series arrangement and a common electrolyte passing there through. The electrolyzer utilizes both sides of the electrodes except for the end electrode with a micro-porous separator isolating each pair of electrodes. The electrolyte passes from cell to cell through electrolyte and gas channeling and between the cells which effectively reduces electrical short circuiting within the electrolyzer.The electrolyte and gas channeling carries the electrolyte to and from each cell to effectively reduce shunt currents between the cells and prevent short circuiting of the electrolyzer while still utilizing a common electrolyte and cooling the electrolyte.
