I didn't know that Martin and Lennon coined the term, but it fits. I'm 
surprised it isn't a household name too! I did know that hand flanging was 
how it origianlly was done.
Flangers are usually knowin for the sweeping effect that they use (by varying 
the amount of time between the original and the delayed sound, usually very 
very small amounts of delay anyway). Changing the time back and forth slowly 
usually modulated with a sine or triangle wave about one cycle every 5 
seconds or so so that the harmonics wink in and out. Jimi Hendrix, obviously 
the Beatles, hits like Itchy Coo Park , Axis Bold as Love and many many other 
tunes used and abused the flanging concept. During the disco era, bass 
players had a sound that used flanging in it... slow rolling flanging with 
lots of feedback giving a resonant peak that moves back and forth. Sometimes 
the center frequency can be tuned and then the amplitude and frequency of the 
"roll" can be dialed in, and season your feedback to taste and you got it.
One very effective use of a flanger is to set it static with none of that 
sweeping stuff and tune it in to comb out 60 cycle hum (along with the often 
more annoying harmonics present thereof), does an amazingly good job of 
elminating it at the risk of a slight "flanged" sound (take your pick which 
is the most annoying thing in your particular application).
 
That's a quick and dirty overview of flanging for the uninitiated.
