The Project Gutenberg Encyclopedia Volume 1 of 28 These changes of resistance are not due to heating of the conductor or the selenium, and the following instance will illustrate this. Scientific American Supplement, No. 492, June 6, 1885 Gives off fumes smelling strongly of selenium and coloring the flame blue. A System of Instruction in the Practical Use of the Blowpipe Being A Graduated Course Of Analysis For The Use Of Students And All Those Engaged In The Examination Of Metallic Combinations And finally—for I must be brief—we have the remarkable action of light on selenium. Scientific American Supplement, No. 275, April 9, 1881 A scale must be prepared, with the zero point at the greatest possible resistance of the selenium, which corresponds with absolute darkness. Scientific American Supplement, No. 484, April 11, 1885 Its action is based on the peculiar property of selenium, which, you probably know, changes its electrical conductivity under the influence of light. Guy Garrick I have one cell in which the selenium has about one-fourth inch square of surface melted on a brass block one inch thick. Scientific American Supplement, No. 492, June 6, 1885 An orange vapor is eliminated if the selenium be present in any quantity, while there is an incrustation around the assay of a grey color, with a metallic lustre. A System of Instruction in the Practical Use of the Blowpipe Being A Graduated Course Of Analysis For The Use Of Students And All Those Engaged In The Examination Of Metallic Combinations These holes are filled with selenium, heated, and then cooled very slowly, so as to obtain the maximum sensitiveness. Scientific American Supplement, No. 275, April 9, 1881 The greatest effect of the light would be to annul the resistance of the selenium. Scientific American Supplement, No. 484, April 11, 1885 It was evidently a very peculiar property of the substance, selenium. The Exploits of Elaine Dual state of selenium.—My cells, when first made seem to have two states or conditions. Scientific American Supplement, No. 492, June 6, 1885 If a substance containing selenium be placed in a glass tube, closed at one end, and submitted to heat, the selenium is sublimed, with an orange-colored vapor, and with the characteristic odor of that substance. A System of Instruction in the Practical Use of the Blowpipe Being A Graduated Course Of Analysis For The Use Of Students And All Those Engaged In The Examination Of Metallic Combinations A small brass wire passes through the selenium in each hole, without, however, touching the plate, on to the rectangular and vertical ebonite plate, B, Fig. Scientific American Supplement, No. 275, April 9, 1881 He went over to the new selenium telaphotograph and began adjusting it. The Romance of Elaine Sequel to "Exploits of Elaine" Kennedy picked up the selenium cell and a long coil of fine wire which he placed in a bag. The Exploits of Elaine During the process of melting and crystallizing, the selenium is compressed between the metal plate upon which it is melted and another plate of steel or other substance with which it will not combine. Scientific American Supplement, No. 492, June 6, 1885 The faithful little selenium cell burglar alarm had done the trick. The War Terror C. Contacts connected to insulated wires from selenium. Scientific American Supplement, No. 275, April 9, 1881 He took out a large instrument composed of innumerable coils and a queer battery of selenium cells. The Romance of Elaine Sequel to "Exploits of Elaine" Then he came back and lifted his hat, hiding as much as possible the selenium cell, letting the light fall on it. The Exploits of Elaine My standard size of cell has about two by two and a half inches of surface, with a thickness of 1/1000 to 5/1000 inch of selenium. Scientific American Supplement, No. 492, June 6, 1885 I knew that selenium was a good conductor of electricity in the light, poor in the dark. The War Terror All the contacts correspond one with the other, both on the side of selenium current and that of the motive current. Scientific American Supplement, No. 275, April 9, 1881 Kennedy was busy adjusting the apparatus, and paused only to remark that the boxes contained two sensitive selenium surfaces balanced against two carbon resistances. The Dream Doctor Meanwhile Clutching Hand himself had approached the table to recover his weapon and had noticed the queer little selenium cell. The Exploits of Elaine When the bridge is balanced, one-half of the current flows through the cell and acts upon the selenium. Scientific American Supplement, No. 492, June 6, 1885 Bismuth and selenium produce the best result, but selenium is expensive and not easy to manipulate. The Story of Electricity At each selenium contact of the rectangular disk there is a corresponding contact to the battery and electro-magnet. Scientific American Supplement, No. 275, April 9, 1881 Because," he went on seriously, "that case interrupted a long series of tests I am making on the sensitiveness of selenium to light, and I want to finish them up soon. The Dream Doctor There was not a soul in the room, nothing but the selenium cell, the chairs, the desk. The Exploits of Elaine In conclusion, I would say that the investigation of the physical properties of selenium still offers a rare opportunity for making very important discoveries. Scientific American Supplement, No. 492, June 6, 1885 The action of the photophone is based on the peculiar fact observed in 1873 by Mr J E Mayhew, that the electrical resistance of crystalline selenium diminishes when a ray of light falls upon it. The Story of Electricity The unequal and slow sensitiveness of the selenium likewise obstructed the proper working of the apparatus. Scientific American Supplement, No. 275, April 9, 1881 Up-stairs in the art-gallery he next installed several boxes such as those which I had seen him experimenting with during his tests of selenium on the afternoon when Mr. Spencer had first called on us. The Dream Doctor Luckily I've got plenty of selenium plates for the sending end. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune If the light is varied properly, by any suitable means, a telephonic or other corresponding current is produced, which can be utilized by any suitable apparatus, thus requiring no battery but the selenium cell itself. Scientific American Supplement, No. 492, June 6, 1885 But the field is yet open to others, for the discovery of a battery which may be still better for use with selenium cells. Scientific American Supplement, No. 492, June 6, 1885 This apparatus requires two batteries, as, in fact, do all autographic telegraphs—one for sending the current through the selenium, and one for working the receiver, etc. Scientific American Supplement, No. 275, April 9, 1881 The optophone translates light into sound by means of that wonderful little element, selenium, which in darkness is a poor conductor of electricity, but in light is a good conductor. The Dream Doctor I must try a different solution of selenium on the metal plate. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune Furthermore, the paths of the current and of the light have been transverse to each other, so that the two forces partially neutralize each other in their action upon the selenium. Scientific American Supplement, No. 492, June 6, 1885 Moreover, even the fusion of the selenium would not produce any such change. Scientific American Supplement, No. 492, June 6, 1885 They take this dust and treat it with acids until they get the pure selenium. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune I had made up my mind to use force, if necessary, to separate Kennedy from his study of selenium. The Dream Doctor I was speaking about selenium, a sort of metallic combination that is a peculiar conductor of electricity. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune My form of cell is a radical departure from all previous methods of employing selenium, in all of these respects. Scientific American Supplement, No. 492, June 6, 1885 I shall probably have to use the metal called selenium, which is very sensitive to light, and which makes a good or a poor electrical conductor according as more or less light falls on it. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune And I'll put in the most sensitive selenium plate I can make. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune Then he glanced at the selenium plate, on which he hoped, some day, to imprint an image from over the wire. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune Perhaps it will be easier if I say that sometimes selenium is found in native sulphur. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune The two surfaces of the selenium act differently toward currents sent into them from the contiguous conductors. Scientific American Supplement, No. 492, June 6, 1885 A small shelf had been fitted up in the booth, or closet, and on this was the apparatus, consisting of a portable telephone set, and a small box, in which was set a selenium plate. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune "But I don't exactly understand how it happened," said Ned, in some bewilderment, as he gazed at the selenium plate. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune I'm going to use a still stronger current, and this is the most sensitive selenium plate I've turned out yet. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune Well, since we can't go motor boating, I guess I may as well go back and see if that new supply of selenium has come. Tom Swift and His Photo Telephone or the Picture That Saved a Fortune I use this current for actual working purposes, among others, for measuring the resistance of other selenium cells, with the usual Wheatstone's bridge arrangement, and for telephonic and similar purposes.
