  • Lama
    bubble allows a complete panoramic view without the dimensional distortion inherent in flat view ports The conventional flat face plates used on virtually all helmets reduces the field of vision telephoto effect and causes a 30 magnification in the apparent size of objects viewed The sense that the image is magnified disappears after a few dives with a flat port helmet since the brain quickly learns to interpret the received image in spite of the actual distortion text from nuytco com The Lama helmets are still available and sold by the Nuytco research Ltd company We normally look at the underwater world through flat surfaces such as the calm surface of a lake river or ocean the window of an aquarium or the flat viewing port of a swimming pool You may have noted how much bigger and deeper a swimming pool or aquarium appears when empty it is simply undistorted by a flat viewing surface Diving with the Lama Newt allows the wearer to experience the underwater scene in its real dimensions If you are an experienced diver and have already learned to interpret the field of view through a scuba mask or flat port diving helmet your brain will automatically supply the required flat port correction and everything viewed through the Lama Newt will appear to be too small or too far away relax this is just an artificially induced 30 reduction and will soon disappear when your brain unlearns the correction First time divers adjust very quickly because they have much less to unlearn Be patient it will take a few dives for the new interpretation to be assimilated and the view through the Lama Newt will be perfectly normal and you will see the under water world as it actually is free of dimensional distortion Here

    to work with Hans because his research was officially defined as important for war Especially for finding new food for the people and finding new methods catching fish and fish farming Q What can you tell me about Barakuda I have seen several Barakuda rebreathers they look like the 138 to me Here you can see a picture of the mentioned rebreather Fotos Modell 138 I was told that Dräger supplied the sports market through this German barakuda company but could not find anything about barakuda Do you have background info on this trademark company A The Barakuda Gesellschaft für Wassersport was founded 1949 in Hamburg by Hans Joachim Bergann and Kurt Ristau both former German frogman in WWII Barakuda had no own factory to build diving gear it was only to distribute the Dräger oxygen rebreathers Starting in 1953 they had the following Dräger oxygen rebreather for sale First the type Tuemmeler than Delphin I and than Modell 138 if you have any info about the Tuemmeler the Delphin I please sent it to me Q How did Dräger changed the gear from a Gegenlunge name the unit Hans Hass dived with Due to the very intense testing the Dräger company used to do I can hardly imagine they just modified a unit an gave it to Mr Hass I read the 60 or so pages about the development of the Heeresatmer in the Dräger Auer fight they do very thoroughly research before putting things in practise A I enclose some illustrations from the original Dräger Hass Geraet which was used by Hans Hass between 1942 1950 It was a modified Gegenlunge and NOT identically with the later Model 138 Q Did the unit of Mr Hass performed as a model to develop other rebreathers like the 138 and

  • Gunning Wrecks
    of a comb like landing Each cleat tilted upwards nearly 25 degrees putting the riders toes unnaturally higher than their heels Two years later in 1898 Charles D Seeberger and the Otis Elevator Co produced the first escalator with true steps having vertical risers and horizontal treads The steps of the Seeberger type escalator became defined as they emerged from the floor and then flattened out along long runs at the upper and lower landings allowing riders to step on and step off At each exit riders were directed off the escalator by an angled balustrade under which the flattened steps disappeared At the beginning of the 20th century the only companies selling escalators were the Reno Inclined Elevator Co and Otis In 1911 Otis acquired Reno s company and the rights to all his patents Reno continued to work for Otis until 1920 when he left to organize the Reno Marine Salvage Co which manufactured vertical pontoon systems to salvage sea vessels During his lifetime Reno was awarded 12 escalator patents Early installations of Reno type escalators around the world included Earl s Court Station London Underground 1912 Salon Rajo Theater Mexico City 1912 T Eaton Company Toronto 1913 Nordiska Kompaniet Stockholm 1914 and Mitsukoshi Department Store Tokyo 1919 The world s oldest escalator may be a Reno type installed in 1917 at Strawbridge Clothier in Philadelphia Pennsylvania Otis installed its last Reno type escalator in 1924 In those early years only department stores and public transportation systems showed any interest in escalators In an effort to improve sales Otis redesigned the escalator in 1920 combining the best features of both the Reno and Seeberger designs The new L type escalator became an instant success The new models had steps which were combed much like the Reno but remained horizontal from comb to comb Combed treads and landings eliminated the need for long space wasting shunt runs while ensuring maximum comfort and safety As a result Otis sold more L type escalators from 1920 1922 than all earlier models combined Reno s engineering talents were not restricted to the field of vertical transportation Shortly after he graduated from Lehigh University in Pennsylvania in 1883 he went to Colorado and began a career as a mining engineer He also worked as an electrical railway expert for the Thompson Houston Co of Boston and the Edison Electric Co of New York and he is credited with building the first electric railway in the soutern United States in Georgia in 1891 The same year the escalator made its debut at Coney Island Reno submitted a comprehensive plan to build a subway system to the Rapid Transit Commission of New York His plan described a double decked underground railway which could be built in three years It included the idea of conveying passengers underground via his incline elevator Although the plan was not accepted by the commission his idea to use escalators in subway systems was widely supported and he was later recognized

  • Expeditions page
    tot een van de meest spraakmakende wrakken van de USA Voor de Oostkust van Amerika vergaan op 26 juli 1953 behoort de Doria voor vele duikers tot een enorme uitdaging Dit schip ligt op ca 240 250 ft diepte en kan in principe alleen met trimix of rebreathers bedoken worden In 1996 waren er helaas nog drie duikers die met lucht deze diepte bedoken Zij kunnen het helaas niet meer navertellen Vanuit de gehele wereld worden vele expedities op dit wrak ondernomen De onderstaande links hebben betrekking op de geschiedenis van het wrak en er is 1 link naar een organisatie die voor trimix duikers trips organiseert LINK LINK LINK Egypt expedition 2001 Eind juni 2001 werd een expeditie uitgevoerd op de P O liner Egypt Het schip ligt op 125 meter diepte in de golf van Biskaje Gezonken in 1922 met 10 ton zilver en 5 ton goud aan boord is er uiteraard al enorm veel moeite gedaan deze buit te bemachtigen Op de foto links ziet U dan ook de meest efficiente manier waarop het goud en zilver werd geborgen Een kleine 1 bar bathyscaaf werd neergelaten op het dek Hiermee werden aanwijzingen gegeven hoe een grote grijper explosieven op het dek moest leggen Daarna werden de wrakdelen stukje bij beetje opgeblazen tot de 3e laag onder het dek werd blootgelegd Voor de 2001 expeditie viel niet veel goud meer te halen Er waren nog wel wat restjes LINK Pearse Resurgence New Zealand 2001 Voor het eerste bedoken in 1975 waren de Pearse grotten reden voor het maken van een documentaire in 1995 Helaas kwam hierbij een van de teamleden om Deze duiker werd in 1997 door de volgende expeditie gevonden In 2001 werd een vervolg expeditie gehouden Om deze zeer afgelegen plek te bereiken zijn helicopters nodig om bij de ingang van de grot te komen LINK 1995 LINK 1997 LINK 2001 The expedition led by submarine hunter Innes McCartney will be the first attempt by technical divers to survey and identify the wrecks of German U Boats scuttled by the Allies after WWII in the waters north of Ireland There are 54 submarines which lie within the depth reachable using today s technical diving equipment and methods and it is believed that the wrecks of these vessels sunk during Operation Deadlight could in future be seen as one of the world s greatest naval heritage sites and compared to such locations as Bikini Atoll Scapa Flow and Truk Lagoon LINK HET IDEALE WRAK In 1995 om 3 00 s morgen gezonken vormt het schip KOHO MARU wellicht het ideale wrak Met 60 meter verticaal vanaf de zeebodem tot 5 meter aan de oppervlakte wordt je wrakduikmodule een eitje Lees maar verder over dit bijzondere wrak LINK DEEP SHIT FROM DOWN UNDER Ooit gedacht dat het mogelijk is om op 80 meter naar de WC te gaan Sinds kort mogelijk in Townsville AUSTRALIE Deze informatie ontving ik van Kerry McKenzie LINK is DOWN O2 Technical Diving expedition
