How is engine fuel kept from freezing? The following table shows the operating temperature of Jet fuels (Source http://www.skybrary.aero/)

I know a lot of flights will be cancelled during bad weather conditions including the cold. How is the Engine fuel kept from freezing when the flight is operated at the mentioned fuel freezing temperature?
In regions and weather conditions where this is likely to be a problem, other fuels are used instead of Jet-A.  

For example, Jet-B has a freezing point of -60C and is used during the winter in some parts of Russia and other very cold places.
