[vcf-midatlantic] analog computers do real work

I met a fellow who used an analog computer for factory molding
(making parts with a heated mold).
The heater control was not just a thermostat
but calculated the acceleration of heat transfer
to keep the part at the proper temperature.
Definitely the job for an analog computer (till recently).

I'm unsure what tech was used (tubes or transistors).
