Fusee-type flares

Fusee-Type Flares. See Ohart (1946), p 306 and in this Vol, p F64, under Flares... 

This expensive, toxic, high ash forming, unorthodox formula developed by the author for a fusee-type signal flare has nothing to re- ... 

Aspects of special effects described in this chapter include fuses (quickmatch and plastic fuse), lances (small coloured flares), set-pieces and devices (assemblies consisting of various types of fireworks linked together), flash, bang and whistle compositions and daylight fireworks (smoke puffs and coloured smokes). Finally, the electrical firing of firework displays is discussed. 

Ca phosphite. Its operation was exactly the same as the Type 94 Float Flare described above Navy Flare Ball was a large cardboard sphere 9 inches in diam with a dome top covering a paper-covered BkPdr Fuse and a dome bottom contg BkPdr chge in a celluloid cap. The main container carried a cluster of 12 flares attached to a large green tissue parachute. The flare cluster was bedded in a quantity of cottonseed which filled most of the lower half of the sphere. A pull wire permitted removal of the top dome and allowed access to the BkPdr fuse for ignition (Ref 1, p 247, Fig 409)... 

Mark 5 Flares, Types 1 and 2 consisted of a cylindrical buoyancy chamber which contd two candles. To these were attached a fuze, a static cord and a pull igniter. The static cord functioned either the arming device of the fuze or the pull igniter. When the device was released (from a container) over the water it went under the surface and then came up. It floated with the head of the flare just clear of the water. When the 1st candle was about % burned out, a piece of safety fuse running to the 2nd candle was ignited and, after a short delay, die 2nd candle started to bum. Each candle burned for about 2% min... 

Fusee. (Amer)(Pronounced "fa-zee"). An obsolete term for a fuse or detonator. At present, the name applies to a long-burning flare (about 20 minutes) used mostly for railroad emergency signalling. It has the appearance of a big candle and can be stuck into a wooden tie by means of a spike. It is ignited by scratching since a match type igniter forms a part of the fusee... 

The Signal, Smoke and Illumination, Marine AN-Mk 13 Mod 0 (formerly Signal, Distress. Day and Night AN-Mk 13 ModO) leads to the well-known commercial railroad fusee which is also a military item under the designation of M72, Railroad Warning Fusee red 20 min. This is the most popular size (about 16 in. overall with spike and cap). Shorter and longer ones of 5—30 minutes B, T. exist. The 30-min flare as well as yellow and green flares of this type are commer al items. 

These types of observations with lUE have been supplemented by more sensitive observations with the HST spectrographs and extended to shorter wavelengths by the HUT on the Astro Spacelab shuttle missions and by the newly operational FUSE. Also, somewhat surprisingly, many late-type stars have been detected by the EUVE (which is most likely seeing EUV emissions from the chromospheres and coronas of these stars, as well as occasional flare activity).
