  • 1904

    Aktiebolaget Gasaccumulator Company (AGA)

    AGA's origins date back to 1904 and are based on the technically ingenious inventions of one man — Gustaf Dalen — who was not only one of Sweden's most important Nobel Laureates but also the only laureate to create an industrial group.

    The AGA industrial company (Aktiebolaget Gasaccumulator Company) was founded to focus mainly on acetylene gas for railway signaling. Soon the company employed Gustaf Dalen as chief engineer and workshop manager where his inventions enabled AGA to grow rapidly. It was the company's inventions with lighthouse technology, the flashing beacon in 1905 and the sun valve in 1907, which were to dictate the company's future. In 1906 Gustaf Dalen became chief engineer at the Gas Accumulator Company; AGA was one of the most innovative companies in Sweden and produced a large variety of products that grew every year.

    The 'Dalen Flasher' reduced gas consumption by more than 90%. The AGA lighthouse equipment worked without any type of electric supply and was thus extremely reliable.

  • 1909

    Gustaf Dalen as AGA Managing Director


    In 1909 Gustaf Dalen ascended to the position of Managing Director of the renamed company Svenska Aktiebolaget Gasaccumulator (AGA). AGA developed lighthouses using Dalen's products. In 1910 the company bought a large real estate in Lidingö and built a production plant that was completed around 1912, and they moved out of the facilities in Stockholm.

  • 1912

    Minutes Before the Disaster — Gustaf Dalen's Accident

    Early in 1912, Dalen was testing maximum pressure for the acetylene cylinders when a cylinder exploded, seriously injuring Dalen and destroying his sight. This picture depicts the test minutes before the accident (Dalen is on the right foreground). Later the same year, he was awarded the Nobel Prize for physics. Despite his blindness, Dalen controlled AGA until his death in 1937. He received over 100 patents during his lifetime.

    Gustaf Dalen received the Nobel Prize in physics, for his invention of the sun valve (Swedish: solventil, "solar valve"), a device that, except for a small pilot light, only released gas during the flash stage to the acetylene flasher. This device used the same principle applied on today's electric systems as photocells.

  • 1913

    Gas Accumulator Company (United Kingdom) Ltd (later Pharos Marine) is founded.


    Named after the famous lighthouse that stood on the Isle of Pharos in Alexandria, Egypt, Pharos Marine began making aids to navigation more than 100 years ago.

    AGA (America Gas Accumulator Company, later Pharos Marine) provided the first 17 light buoys with 300 mm acetylene gas lanterns for the ISHTMAN CANAL COMISSION - Panama Canal

  • 1928

    The revolutionary Lampchanger

    The first electrical light source was made practical by the innovation of the Lampchanger, Wallace & Tiernan, models FA-147 and FA-148.

    Charles F. Wallace Founder of "Wallace & Tiernan" and inventor developed and patented this first Lampchanger in 1928. This patent established the Wallace and Tiernan Company as the pioneer in the electrification of aids to navigation lighting. Pharos Marine Automatic Power Inc. are heirs to this Wallace and Tiernan Company legacy.

    Automatic Power traces its roots to Charles Wallace's original 1928 Lampchanger patent. Wallace's Lampchanger consisted of a rotating carriage holding a Model T headlight lamp at the focal point of an optic. When the operating lamp failed, a new lamp automatically rotated into the operating position.

  • 1938

    First electro mechanical Lampchanger


    FU-1247 (later redesigned and renamed APL-1297) by Wallace & Tiernan, The first electro mechanical Lampchanger to be used in combination with electrical flashers, FU-1297 units were produced starting in 1938 with 5 to 16 Volts AC or DC operation. Typically this unit was used on Wallace & Tiernan 150mm, 200mm and 300mm lanterns.

  • 1947

    Light House Inc. (later Automatic Power Inc.) is founded

    Nathan "Available" Jones, founder and owner of The Light House Inc., Buoys Inc. and The Lighthouse of LA. Inc., was nicknamed "Available" because he never refused to take a sales call, and always answered customers with something like "yes we could do that, not a problem".

    First Lighting Offshore Drilling Rig in the Gulf

    The first commercial offshore oil rig began drilling in 1947 18 miles off the coast of Louisiana, in the Gulf of Mexico, near St. Mary Parish, LA in just 18 feet (5.5 meters) of water. Light House Inc. supplied four 5-nautical mile lanterns and one and half mile fog horn for this first oil rig. This Gulf of Mexico project became the first platform lighting system.

  • 1949

    The first 2-mile fog signal is implemented in Gulf of Mexico


    Nathan "Available" Jones (founder of The Light House Inc., Buoys Inc. and The Lighthouse of La. Inc.) along with his neighbor Hueling Parker, working in Hueling's garage, designed and built a control panel for the first prototype Model M-18 dual diesel air 2mile fog signal. This unit was 8ft wide, 10ft long, and 8ft tall; it weighed about 4 tons loaded. It contained 2 Buda 2-cylinder diesel engines, driving a 30 cfm Ingersol air compressor, with an internal 360 gallon fuel tank, automatic oil filling and water filling system, air receiver and a quad set of Cunningham. Air whistles (Leslie?s horns) were mounted on top of the roof of the building.

  • 1959

    First Wind Generator on the Gulf of Mexico


    In 1959 Automatic Power installed a 4.7kw wind generator on a Conoco Platform off Grand Isle, LA.

    It was rated at 4.7kw 120 volts DC. Also installed was a 120Vdc 500 ampere hour battery standby system as well as a 3 cylinder Nordberg Diesel engine with a 20KW 120 volt DC generator.

    The wind generator was made in Germany and had 40 foot diameter metal blades with automatic positioning for wind orientation and over speed/high wind shutdown protection.

    Conoco used the energy to power the aids to navigation, the cathodic corrosion protection system for the platform, power for the well control, and a temporary quarters building used if personnel had to be on the platform overnight.

  • 1960

    The first precision molded acrylic lenses


    Precision molded acrylic lenses were developed to take advantage of the same Fresnel principle used on the glass lenses. These lenses are now used with the 155mm lanterns for buoy and beacon applications with electrical Lampchangers.

    First "Made in Houston" Fog Horn, DA-8


    The DA-8 was the first electric Fog Horn totally designed and manufactured in our offices in Houston; this horn served the Oil and Gas businesses of the Gulf of Mexico and several worldwide projects for more than 25 years. The DA-8 was a proven, reliable sound emitter for use on offshore platforms. The horn was designed at an optimum frequency to maximize its range rating for both U. S. Coast Guard and IALA criteria. Eight emitters were stacked in a vertical array on a marine grade aluminum or, optionally, stainless steel support structure. The tower base included a hinge to facilitate lowering of the tower.
