NITROGLYCERIN AKTIEBOLAGET (NITROGLYCERINE LIMITED) Nitroglycerine Explosives according to the Dr. Alfred Nobel patented process Products: Dynamites of all kinds, especially "Extra Dynamite" Safety Explosives, especially Nitrolite Perchlorate Explosives, Territe, and ✩Territe ✩ Black Powder of all kinds, Smokeless Powder General The Gyttorp factory Part of a day's output 6 tons of explosives Already in the first year of its existance the Nitroglycerine company carried on manufacturing of blasting oil on a small scale in temporary quarters, the product being used to some extent for practical purposes, notably in blasting the railway tunnel underneath the southern section of Stockholm. Subsequently a permanent explosive works was erected at Vinterviken, near Stockholm, in 1865, for the production of nitroglycerine. This factory was the first of its kind in the world, and served in many respects as a model for the nitroglycerine works founded successively in other countries by the late Dr Alfred Nobel. The improvements in the manufacture resulting from Dr Nobel's inventions of Guhr and Extra Dynamite led to corresponding developments in the Vinterviken establishment as well. New factories were erected for the manufacture of the constituent products, such as sulphuric acid, nitrate of ammonium, nitrocellulose, etc. When Dr Nobel, towards the end of the eighties, had evolved his methods for the manufacture of smokeless nitroglycerine powder, »Nobel Powder », the manufacture was taken up on an extensive scale at Vinterviken in 1890. The Nobel powder patents, however, were transferred in 1898 to the Bofors Nobel Powder company, founded as an affiliated concern to the then Bofors-Gullspång company. In 1914, the Nitroglycerine company acquired the works of the Gyttorp Explosives company founded in 1858 for the purpose of making black powder. Later, in the eighties, the company added to this line the manufacture of nitroglycerine explosives. These works are favourably situated in the large mining district of Central Sweden, and comprise departments for the production of dynamite and similar explosives, black powder, smokeless powder and shooting ammunition. They have been greatly extended and modernized, and have now a capacity amply sufficient to meet requirements of the home as well as the export market. The manufacture of these products at Vinterviken has consequently been closed down. The various types of dynamite invented by Dr. Nobel for different purposes have during the past fifty years maintained and strenghtened their dominant place in mining operations. This is especially the case where the hardness of rock, such as usually is the case in Sweden, places great demands on the effectivity of the explosive. The Nitroglycerine company is manufacturing dynamite of all usual types, especially »Nobel Extra Dynamite ». In 1910 the company introduced a new, patented type of explosive, »Territe », and »Territe », consisting mainly of perchlorate of ammonium. It is chiefly characterized by good moulding properties, high specific gravity, etc., and can best be likened to dynamite, and, in addition to possessing the qualities of the latter, it has the advantage of being practically freezeproof. Although not comparable in effect with the powerful types of dynamite, it has, however, been proved that the safety explosives based on nitrate of ammonium, first suggested by the Swedish inventors Norrbin and Ohlsson, may, on account of their lower cost, be used to great advantage in blasting operations of less exacting nature, such as blasting of tree stumps, boulders, etc. Such a safety explosive is »Nitrolite » manufactured by the Nitroglycerine company. This product besides being very effective also possesses the valuable quality of being insensitive to knocks, blows and fire. Dynamite Territe Nitrolite Gyttorp cartridges Cartridge test Special train from Gyttorp to Ervalla on the 22nd of April 1922 composed of 46 trucks carrying 165 tons of first class explosives. The manufacture of shooting ammunition has of late years assumed large proportions at the Gyttorp works. »Gyttorp » cartridges have a splendid reputation both in Sweden and abroad on account of their effective shooting properties. A test certificate issued by the Government Munition Works at Åker is reproduced here, and is conclusive on this point. |
