| titleOfInvention | Improvements in and relating to electric condenser and methods of manufacturing the same |
| abstract | 262,443. British Thomson-Houston Co., Ltd., (Assignees of Boyer, S.). Dec. 4, 1925, [Convention date]. Condensers are made with a dielectric of wood, which is preferably impregnated with a material having a high dielectric constant and resistivity, such as transil oil, nitrobenzene, nitrotoluene, acetonitrile, asphalt and the like. A suitable wood is balsa wood which is cut, seasoned, dried, and vacuum treated to free it from volatile impurities and then impregnated, after which it may be compressed to any desirable thickness. A condenser having such a dielectric is stated to possess a high capacity, so allowing of the use of a, thicker dielectric separation and reduced voltage gradient. The Specification also refers to the use of red wood, cork, and paraldehyde. The Specification as open to inspection under Sect. 91 (3) (a) states also that wood treated in this way can be used as an insulating material, for example, for radio panels and the like. This subject-matter does not appear in the Specification as accepted. |
