Wireless Transmission of Photographs Second Edition, Revised and Enlarged 1919

In the present chapter it is proposed to give a brief description of a system of radio-photography devised by the author, and which includes a greatly improved method of transmi...

There are only two methods available at present for receiving the photographs, and both have been used in ordinary photo-telegraphic work with great success. They have disadvant...

The connections for an experimental syntonic wireless transmitting station are shown in the diagram Fig. 4. A is the aerial; T, the inductance; E, earth; L, hot-wire ammeter. Th...

Clockwork and electro-motors are the source of driving power that are most suitable for photo-telegraphic work, and each has its superior claims depending on the type of machine...

capacity effects are very slight, with the marvellous speed of 12,000 a minute, but this speed rapidly decreases with an increase of distance between the {5} [Illustration] two...

Those who desire to experiment on radio-photography, _i.e._ transmitting photographs, drawings, etc., from one place to another without the aid of artificial conductors, must cu...

[4] In wireless telegraphy "arcing" is principally caused by the continuation of the supply current in the spark-gap after the capacity has been charged to a potential sufficien...
