65            <p>Humans always wanted to communicate over very long distances. In the early 20th century

117      <p>It is quite incredible: Fax machines were already mass-produced in 1929. However, it
118      was difficult to run these machines. The first pracitcal fax machines are a german invention: The "Normalpapierfax" (a fax machine that
119      used usual paper) from Siemens-Hell, year of manufacture 1956, with tube technology, is still completely runable.
120      An unhurried and transparent fax transmission (DIN A5) takes about 4 minutes. Theoretically you
121      could send a colored fax with that machine!</p>

125              <p class="bildtext">The <b>Fultograph</b> is an <b>"image reciever"</b>, invented by the
126                 Englishman Otho Fulton in 1929.
127                 This devices made it possible to transmit weather chartes by funk for the first time.
128                 <br />The rotating roll, which had been coated with chemically preperated paper, was spirally
129                 scanned by an attached "pen" (tabluator). In this way an electric current could flow
130                 from the pen over the paper to the roll in the rythm of the picture informations. That way, the
131                 image developed by electrolysis.</p>

137              The <b>Siemens (HELL) fax machine KF 106</b> is very rare. This "remote copy machine" was produced in
138              1954/55. The ink-based write approach was already matured. Sad to say, the service-friendliness was quite
139              bad. The bulky device (27 kilogram) scans only a DIN A5 sheet. Already 1956 the successor KF 108
140              came on the market, with great improvements.

146          <p class="bildtext">
147              The illustration shows the <b>SIEMENS fax machine KF 108</b> (year of manufacture 1956).
148              <br/>It works in a similar way like the Fultograph. Instead of the electrochemical recording,
149              ink is put on the usual paper by the help of complex mechanics.
150
151              <br/>It works similar to the fultograph. Instead of a electochemical notation, ink is brought by a small rotating sapphire reel onto normal paper.
152              <br/>A KF 108 will even be able to send and recive faxes when the modern fax devices are trashed. Of course, it is not compatible to today's devices. Siemens produced the device in a typical german manner: Everything is huge and indestructible. In these days you did not throw everything away.

194    <!-- paragraph between Hellschreiber and teletype:
195         translated 27. July 2008 from de -->
196    <p>Nevertheless the clatting teletypes coined high speed
197       telecommunication for decades. The first teletype was presented
198       in 1930 by Siemens &amp; Halske &ndash; only three years later,
199       the German Post used them for communication all over Germany.
200       The first official connection in Germany was build between the capital, Berlin,
201       and the Hanseatic City of Hamburg. Unlike the
202       Hellschreiber, the teletype did not use the already existing
203       telephone network, so they had to build up a seperate telex
204       network.
205       <br/>
206       At first there were only 21 subscribers in 1933, but only six
207       years later, they counted 1500 subscribers in 1939. In 1975
208       there were actually more than 90,000 subscribers. In these
209       days, the mechanically working teletypes were replaced by
210       electronically driven devices (Telex). Even nowadays, in
211       times of the internet, a few developing countries use this
212       disaster safe kind of communication.</p>

217            Teletype from Siemens, year of manufacture 1952. Below in the picture, you can see a paper tape sender.
218            While typing the text, it was fed into the paper tape and could be send afterwards quite fast. Basically
219            this is comparable to an SMS or e-mail which is buffered in the device until it is sent in one go.

227     <br/>The electomechanical "text processing systems" (1962-64) show you how texts could be duplicated and written automatically with punched tapes and punch cards as storages.
