Hello Alan,

yes I have this paper, size is too big, so I'll forward it to you directly.

The patent to this 7000 standard is UK patent GB 258 356A, about 
removing of hysteresis of the LTZ.

Actually, it should not function in the 7000 standards, as these run on 
45°C, and therefore the temperature swing is too low, and there is 
usually no hysteresis at this low temperature.

I also have several interesting papers from Spreadbury and Deaver, about 
stabilities / drift behaviour of LTZ1000 and LTFLU.

regards Frank
