[Ferro List] FC Patent Link

[Keith B]

For my money, that's a crap patent which should never have issued.  On 
the other hand, the good news is that it expired on Oct. 8 1998 for 
failure to pay maintenance fees, its brief existence now puts everything 
substantially like that into the public domain, and there are a few 
useful oddments in it, such as a design for a mortar sprayer suitable 
for someone light on engineering skills but with access to a hardware 
store...
