Heribert schreibt 168 Text fuer englische Version in Mail am 169 26. Juli 2008: 170 171 Links: Hellschreiber GL 72 (ca. Bj. 1952). Jede Taste erzeugt eine 172 bestimmte Tonsequenz. Mit diesen Geräten konnte man daher im 173 Gegensatz zu den Fernschreibern im Telefonnetz kommunizieren. 174 175 Rechts: Diktiergerät mit Magnetplatten (Bj. 1952), welches auch die 176 Informationen des Hellschreibers aufzeichnen konnte. Damit wurde es 177 schließlich möglich Text auf einer Magnetplatte abzuspeichern und 178 beliebig oft durch den Hellschreiber "ausdrucken" zu lassen. 179 180 Auf Basis dieses Textes nun meine englische Übersetzung: 181 --> 182 <div class="box center"> 183 <img src="/shared/photos/kommunikationstechnik/hellschreiber.jpg" width="629" height="245" alt="Hellschreiber GL 72" /> 184 <p class="bildtext-bildbreite" style="width:629px;"> 185 The <b>Hellschreiber GL 72</b>, year of manufacture 1952 186 (in the picture on the left). An unique sequence of frequencies 187 is assigned to each key. Thus the device could make use of the 188 telephone network, like the later modems did to build up the 189 internet. This feature distinguishes it from the ordinary 190 teletypes. 191 </p> 192 </div> 193 194 <!-- 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 & Halske – only three years later, 199 the German Post used them for communication all over Germany. 200 The first official connection was build between the capital of 201 Germany, Berlin, 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> 164 213 165 214 <div class="box center"> … … 172 221 </p> 173 222 </div> 174 223 224 <!-- This paragraph was replaced on 27. july 08 in favour of... --> 225 <!-- 175 226 <p>Long time before, telegraph offices (about 1900), the early teleprinters (1938) and Hellschreiber (1952) were used. A demonstration shows something unbelievable: The Hellschreiber writes a dictate from a dictating machine from the early fifties without mistakes!?<br/> 176 227 <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. Only big companies could afford the complex technology which was typically german. See the <a class="go" href="/en/devices/olympia-flexowriter.shtm" title="Olympia Schreibautomat" name="backlink-olympia">Olympia flexowriter</a>.</p> 177 228 --> 229 <!-- ...this paragraph: --> 230 <div class="box center"> 231 <img src="/shared/photos/kommunikationstechnik/olympia-schreibautomat.jpg" width="629" height="242" alt="Olympia Flexowriter" /> 232 <div class="bildtext-bildbreite" style="width:629px;"> 233 <p>As a kind of spin-off products of the teletype 234 development, the electromechanical "wordprocessing systems" 235 (1962–-–1964) were invented. They were capable 236 of duplicating and writing texts automatically, using 237 paper tapes and punch cards as storage media. 238 <br/>The technology of these devices was quite complex 239 – at that time only big companies could afford these 240 typically German devices. 241 <br/>The picture above shows the <b>Olympia flexowriter</b> 242 with two paaper tape readers and one paper tape puncher, 243 year of manufacture 1962.</p> 244 </div> 245 </div><!-- end of image box --> 178 246 179 247 </div><!-- end of content --> -
