AGA verlichting langs het Panamá kanaal




  Zijn studies voltooide, Dalen gevormdheid het bedrijf Dalen & Celsing Samen met zijn rijke medestudent Henry Celsing. At the same time, he worked for Svenska Carbid & Acetylen (later to become AGA). Op de Sametime, werkte hij voor de Zweedse Carbide & Acetyleen (later naar AGA Word). The partners invented the Brilliant gasworks which they sold to the town of Ängelholm. De partners de uitvinder van de Brilliant gasfabriek waarover niet soldaat naar de stad Ängelholm. This work involved a new way of producing and using acetylene gas, mainly for lighting. Dit gebeurde op een nieuwe manier van produceren en gebruiken acetyleengas, vooral voor verlichting. It was also Dalén who introduced welding using acetylene gas in Sweden in 1902. Het was ook “Dalen WHO ingevoerd lassen met acetyleen gas in Zweden 1902





 AGA’s intermittent light regulator reduced fuel consumption by 90 percent, and the
sun valve cut consumption by another 4 percent. This meant lighthouses could be
operated at a low cost and left unattended for long periods of time. In 1912, AGA
won a contract to build a lighthouse system for the Panama Canal and Dalen was
awarded the Nobel Prize in Physics for his inventions in lighthouse technology.

In 1911 the AGA Company was chosen to provide a lighthouse
system for the Panama Canal, and by 1912 an increasing
number of coastal installations in Sweden, and in several
other parts of the world, had installed the Dalén system of
lighting. Dalén’s system made it possible for lights to operate
automatically and without need of inspection for a year
or more. Before Dalén’s system, a lightship in Sweden cost
200,000 Kronor and had an annual maintenance cost of
25,000 Kronor. An automatically operated signal buoy costing
9,000 Kronor with an annual maintenance of only 60
Kronor could now replace this. The Blockhusudden
lighthouse in Stockholm installed the Dalén lighting
system in 1912, and it operated until 1980, having
consumed 1.8 million liters of acetylene by emitting 400 million
flashes in 68 years.
In September 1912 Dalén, then president of AGA, continued
his experiments on handling acetylene. In one particularly dangerous
test involving heating a gas accumulator, the device exploded.
Dalén was seriously injured and permanently blinded by this accident.
Two months after this accident, theNobel Prize in Physics for 1912
was announced.













History of the Amalgamated Gas Accumulator
AGA AB was started in 1904 near Stockholm, Sweden, by Gustaf Dalen, a 35-year-old engineer and ingenious inventor. The very next year AGA developed an automatic lighthouse mechanism that included the sun valve and the intermittent light regulator (the first innovations patented by AGA). Acetylene, with its bright light, was an excellent fuel for lighthouses, but it was too expensive when burned all day.

AGA’s intermittent light regulator reduced fuel consumption by 90 percent, and the sun valve cut consumption by another 4 percent. This meant lighthouses could be operated at a low cost and left unattended for long periods of time. In 1912, AGA won a contract to build a lighthouse system for the Panama Canal and Dalen was awarded the Nobel Prize in Physics for his inventions in lighthouse technology.

In 1911, AGA founded American Gas Accumulator Co. in New Jersey and in ensuing years many lighthouses were installed around the Great Lakes. Although AGA’s stock in American Gas Accumulator Co. was sold in 1949, new operations had been established in other fields in the United States.













Oude kaarten en vuurtorens die niet meer bestaan






Trots framgången med klippljusapparaten var Gustaf Dalén inte nöjd, eftersom han tyckte att det var onödigt att fyrarna blinkade även under dagtid. Då uppfann han solventilen, en av hans mest berömda uppfinningar som blev färdig 1907. Principen är väldigt enkel, nämligen att ett mörkt föremål drar till sig mer solljus än ett ljust föremål. Värmen gör att det mörka föremålet utvidgar sig. Solventilen innehåller en svart stav omgiven av tre blanka. Den svarta staven är kopplad till ett membran som öppnar och stänger gasflödet. När staven utvidgas av solljuset med tvåtusendels millimiter, släcks fyren. När natten kommer krymper staven och gasen släpps åter fram till evighetslågan, så att fyren kan börja blinka igen.
”It won’t work”, lär Thomas Edison ha sagt om solventilen. Men det gjorde den. 1912 fick AGA en prestigeorder och tillverkade alla fyrar för Panamakanalen.





Isthmus of Panama

















In 1912 the company won a huge order in the face of fierce competition. The entire Panama Canal was to be provided with AGA lighthouses.
In September Gustaf Dalén was badly injured in an explosion which left him blind for life. He was still convalescing when the Swedish Royal Academy of Sciences awarded him the Nobel Prize in Physics. At the beginning of 1913 he returned as president, a position he was to hold for another 25 years.
AGA not only became a company in the forefront of technical development but also a social pioneer through its considerable efforts on behalf of its employees.
