| abstract | 468,736. Wireless receiving-apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 27, 1936, No. 29183. Convention date, Oct 30, 1935. [Class 40 (v)] [Also in Group XXXVI] In a detector or like electrode system with unsymmetrical conductivity, in which the electrodes 1, 4 are separated from each other by means of a solid insulating layer 3, one of the electrodes 1, which is semi-conductive, consists mainly of selenium, to which is added one or more iodides to increase the conductivity. Preferably the percentage of the addition is not less than 0À05. A number of iodides, which may be added to the extent of 1 per cent are specified as being very suitable, e.g. mercuric iodide and iodides of bismuth, copper, antimony and tin. Iodine alone may be added, to the selenium, forming selenium iodide, which increases the conductivity. Constituents which combine together to form the iodides may be added separately to the selenium. Several examples of methods of carrying out the invention are described, one of which is as follows. Bismuth and iodine are respectively dissolved in separate quantities of amorphous selenium, melted in containers, and the solutions are mixed, bismuth iodide being thereby formed in a finely divided state. The mixture is applied to a carbon, metal, or carbonized plate, which is rapidly cooled and subsequently heated to convert the selenium to the conductive crystalline state. An insulating coating of polystyrene is applied, and finally a conductive second electrode is formed as a layer of material such as gold varnish or Woods metal. |
