"Wew German Apparatus

‘THE new German electric television invention, the "Telehor," the inventor predicts, will soon be used to transmit moving pictures, the Department of Commerce has just been advised by the Trade Commissioner at Paris, George R. Canty. The "Telehor" transmits direct from object without the necessity of taking preliminary pictures. ‘The report, follows in full text:-~ The "Telehor," the new German electric television invention which is considered to be a step forward in the field of electric television, ¢onsists of two parts, the Sending and the receiving apparatus, both neatly packed away in two cabinets. On one end is the projection lamp that throws the ‘picture of the object to be transmitted

into an apparatus that divides the light waves. The playing of these light rays on sensitive cells produces electrie currents, which are transmitted by wire or without wire to the receiving apparatus that receives the electrie impulses, changes them back to light waves and then to a composite picture. Both machines are synchronised so that only one electric impulse is received and sent at one time. The electric impulses of a picture are sent one after the other. It takes one-eighth of a second to send enough to make a complete picture, But since the eye sees light waves that come at such a frequency as a composite picture, the problem is practically solved. [THE inventor states that this apparatus, which will later be shown to the general public at the Radio Exposition, will be light and compact, and that anyone who has a radio now will very likely have a "Telehor." In a demonstration pictures and objects were put under the lamp, over an opening in the first apparatus, and the pictures were astonishingly clear on the projection plate of the recelying apparatus, it is said, This system differs from the wireless photography already in use in that it is not necessary first to take a picture of the object which is transmitted, The inventor believes that his instrument will soon be used to transmit moving pictures, that research workers will use it to get pictures of places where human beings cannot live, such as the bottom of the ocean, or high-up in the air, and that it will be of use for military purposes,
