Question: During which was did Beatrice Shilling invent a simple technical device made to counter engine cut-out in early Spitfire and Hurricane fighter aeroplanes?
Context: A locomotive winch is a technical device for moving stabled railway locomotives. The Ultimate Nullifier is a device of immense power in Marvel Comics.  The device made its first appearance in "Fantastic Four" volume 1, issue #50 (May 1966), in which Johnny Storm retrieves it from the home of Galactus—as directed by Uatu the Watcher—for the Fantastic Four to employ against the threat of Galactus himself.  The Nullifier appears as a small, hand-held metallic device with no apparent functionality.  When first introduced in 1966 it was described as the only known weapon in the universe capable of inspiring fear in Galactus. The Miles M.20 was a Second World War fighter developed by Miles Aircraft in 1940.  It was designed as a simple and quick-to-build 'emergency fighter' alternative to the Royal Air Force's Spitfires and Hurricanes should their production become disrupted by bombing expected in the anticipated German invasion of England.  Due to dispersal of manufacturing, the Luftwaffe's bombing of the Spitfire and Hurricane factories did not seriously affect production, the M.20 proved unnecessary and the design was not pursued. Levonorgestrel-releasing implant, sold under the brand name Jadelle among others, is a device made up of a two rods of levonorgestrel used for birth control.  It is one of the most effective forms of birth control with a one-year failure rate around 0.05%.  The device is placed under the skin and lasts for up to five years.  It may be used by women who have a history of pelvic inflammatory disease and therefore cannot use an intrauterine device.  Following removal fertility quickly returns. In mathematics, the adjective trivial is frequently used for objects (for example, groups or topological spaces) that have a very simple structure.  The noun triviality usually refers to a simple technical aspect of some proof or definition.  The origin of the term in mathematical language comes from the medieval trivium curriculum.  The antonym nontrivial is commonly used by engineers and mathematicians to indicate a statement or theorem that is not obvious or easy to prove. The operating point is a specific point within the operation characteristic of a technical device.  This point will be engaged because of the properties of the system and the outside influences and parameters. Miss Shilling's orifice was a very simple technical device made to counter engine cut-out in early Spitfire and Hurricane fighter aeroplanes during the Battle of Britain.  While it was officially called the R.A.E. restrictor, it was normally referred to under various names, such as Miss Tilly's diaphragm or the Tilly orifice in reference to its inventor, Beatrice "Tilly" Shilling. James Carlyle Marsters (April 5, 1924 – July 28, 2009) was a deaf orthodontist in Pasadena, California who in 1964 helped invent the first teletypewriter device capable of being used with telephone lines.  The device made communication by telephone possible for the deaf.  Although Robert Weitbrecht did much of the actual design work, Marsters promoted the device's use. A ricercar (] , also spelled ricercare, recercar, recercare) is a type of late Renaissance and mostly early Baroque instrumental composition.  The term means to search out, and many ricercars serve a preludial function to "search out" the key or mode of a following piece.  A ricercar may explore the permutations of a given motif, and in that regard may follow the piece used as illustration.  For example, "Ricercar sopra Benedictus" might develop motifs from a motet titled "Benedictus".  The term is also used to designate an etude or study that explores a technical device in playing an instrument, or singing. Beatrice (Tilly) Shilling OBE PhD MSc CEng (8 March 1909 – 18 November 1990) was a British aeronautical engineer and motor racer.  During the Second World War, she invented "Miss Shilling's orifice", a small metal disc similar to a metal washer that restricted fuel flow to the carburetor helping prevent engine stall in the Rolls-Royce Merlin engines of the Hawker Hurricane and Supermarine Spitfire fighters, which could lose power or even completely cut out during certain manoeuvres; a significant disadvantage in active service.
