Need technical Paper

Please does someone have these following article:

1. Bureau of mines technical Paper no. 450 - Inflammability of mixed gases
2. Bureau of mines report of investigations 3216- Limits of inflammability of natural gas

Thanks

These will be relevant. They are the normal references used when checking for flammability of gas mixtures with high inerts and when designing indirect and direct fired equipment (fired heaters, fire tube heaters, incinerators, boilers etc.):
