Re: [time-nuts] How dangerous if a Rb lamp broken?
Wed, Jul 10, 2013 11:11 PM
Someone will correct me and the thread will never die.) The rate at which a mass of radium becomes inert is expressed as its half-life, which is the TIME that it takes for half of the remaining radium to become inert. The decay is exponential, as are so many natural things.

There are things like ROM’s with known defects that die and are a bit more problematic to replace ( = get the replacement CPU board). Bob > On Dec 18, 2014, at 6:10 PM, Orin Eman wrote: > > #151518774079 > > Currently at $49.95 plus shipping. > > It's showing a ROM error (7.7) on startup.

Re: [time-nuts] Swagelok and metric tubing question
Sat, Nov 12, 2016 5:44 AM
Stainless is very tenacious stuff, and as a result, when it is drawn through a die when sizing it as tubing, it gets axial ridges formed by galling, and damage to the dies.

Re: [time-nuts] Fwd: Dusty 53131A

It is not at all uncommon for them to fill up with dust, overheat, and die. Popping them open every 10 years or so to clean them out is well worth the effort.
