in America in 1907. It essentially provides an iron phosphating process, using phosphoric acid. Parkerizing (also called phosphating and phosphatizing) is a method of protecting a steel surface from corrosion and increasing its resistance to wear. Parkerizing is commonly used on firearms. 1907: Accles & Pollock produce the first tubular sections for aircraft and the first tubular furniture. 1908: Pockley Automobile Electric Lighting Syndicate markets the world's first electric car lights to be sold as a set, which consist of headlights, sidelights and tail lights and are powered by an 8 volt battery. Birmingham's ingenuity and expertise in metal working aids the early production of lightweight tubing used in the construction of successful airplanes. Engineering firms pioneer advances in aircraft engines also such as Austin and Wolseley Motors, who later build hundreds of early aircraft for the British Air force, such as the S.E.5 biplane fighter. Wolseley help to set Vickers on their path to motor and engine development for aircraft at Adderly Park, with a new engine ready for production by 1909. The Wolseley Viper engine is applied to many aircraft around this time and is developed out of the Hispano-Suiza 8. Several other small engineering firms design and build early aircraft engines such as Maxfield & Co, who test an early monoplane in 1909 at Castle Bromwich, the Butterfield Brothers also make an experimental aircraft engine in 1911. Birmingham engineering works later diversify with all manner of industries relating to the development and manufacture of aircraft components including assembly of whole planes during war years such as Spitfires, Hawker Hurricanes, Fairey Battle light bombers, Mercury and Pegasus aero engines, Short Stirling four-engined heavy bombers and Avro Lancasters (towards the end of World War II). 1910: J. R. R. Tolkien begins to construct his first Elfin tongue whilst a pupil at King Edward's School, Birmingham. He later calls it Qenya (c. 1915). Tolkien is already familiar with Latin, Greek, Spanish, and several ancient Germanic languages, Gothic, Old Norse and Old English. Tolkien's parents are from Birmingham and he himself grows up, and studies in and around Birmingham (Tolkien also meets his wife in the town and considers himself a 'West Midlander'). The enduring popularity of The Lord of the Rings later leads to numerous references in popular culture, the founding of many societies by fans of Tolkien's works, and the publication of many books about Tolkien and his works.
