Did You Know...
...that Thomas Edison's patent application on his phonograph was approved by the Patent Office in just seven weeks? In contrast, it took Gordon Gould, the inventor of the laser, 30 years to obtain his patent -- finally awarded in 1988!

| Number | Title | Issue Date |
| 7294233 | System and method for altering the tack of materials using an electrohydraulic discharge A system and method for altering the tack of a material, namely a polymer used as an adhesive, also known as stickies, or pitch. The present invention reduces the tack of the stickies and pitch by exposing the materials for a short duration to low-energy pulsed elec... | 11/13/2007 |
| 7267744 | Pulp treatment and process This invention provides a process for treating chemical woodpulp, or chemical cellulose including cotton linter, including the step of applying an electron processing technology (EPT) step to chemical woodpulp, or chemical cellulose, as the case may be, on an in-lin... | 09/11/2007 |
| 6841058 | Redox bipolar cell fabric washer system A redox bipolar cell fabric washing system and method is disclosed that provides for washing fabrics without the use of any added detergents, fabric softeners, or bleaches, or other chemical al additives. The system includes a conventional fabric washing machine wit... | 01/11/2005 |
| 6511578 | Bleaching and delignifying cellulosic pulp using caroate/caro's acid solution The invention relates to a method of bleaching and/or delignifying cellulose, in which (a) a sodium hydroxide solution and a peroxydisulphate solution are first of all produced by electrolysis of a sulphate, (b) the peroxydisulphate solution is converted by hy... | 01/28/2003 |
| 6187170 | System for the electrochemical delignification of lignin-containing materials and a process for its application System for the electrochemical cleavage of compounds which includes a mediator which has no metals or heavy metals and at least two electrodes for the electrochemical activation of the mediator.... | 02/13/2001 |
| 5810996 | Electro-osmotic transport in wet processing of textiles Electro-osmotic (or electrokinetic) transport is used to efficiently force a solution (or water) through the interior of the fibers or yarns of textile materials for wet processing of textiles. The textile material is passed between electrodes that apply ... | 09/22/1998 |
| 5456809 | Electrochemical mercerization, souring, and bleaching of textiles Economical, pollution-free treatment of textiles occurs in a low voltage electrochemical cell that mercerizes (or scours), sours, and optionally bleaches without effluents and without the purchase of bulk caustic, neutralizing acids, or bleaches. The cell... | 10/10/1995 |
| 5238538 | Method for deinking recycled fiber by applying direct current electric field A method for the deinking of recycled fibers, in which the macerated fibers are slurried with water; introduced to a deinking cell which has a central anode and a perimetal cathode; subjected to a direct current electric field applied between the anode an... | 08/24/1993 |
| 4702807 | Electrochemical process for bleaching wood pulp using chlorate and a redox catalyst An electrochemical process for delignification and bleaching of pulp fibers is disclosed. The process involves the use of metallic chlorates and vanadium catalysts in the presence of an electric current to provide a pulp fiber of improved brightness and v... | 10/27/1987 |
| 4617099 | Electrochemical bleaching of wood pulps A process for electrochemically bleaching pulp which comprises dispersing a pulp in a solution of sodium chloride to provide a first pulp slurry; subjecting said pulp slurry to electrolysis at a pH in the range of about 0 to 2.0; filtering said pulp slurr... | 10/14/1986 |
