[time-nuts] HP10811 Oscillator Thermal Fuse

[Bill Hawkins]

Labs could have used a common gas heater for the crystal ovens, with a
bit of rewiring.

No fire hazard there - you've got a chimney. Also, flame safety is well
developed for gas heaters.

Would have required throttling gas flow control.

Another possibility is circulating hot water.

Ultimately it all came to no good. The energy conservation rules simply
took over. Shutting down everything during off hours became the way a
lot of outfits did things. Don't turn off all your bench gear and you
get a nasty note. I am not aware of full power being dropped during off
hours. That tends to take out things you really do not want to shut down
(fire sensors .).
