How "special register groups" invaded computer dictionaries for decades
For some reason, a 1960 definition of [a computer's] "central processing unit" included "special register groups", an obscure feature from the Honeywell 800 mainframe. This definition was copied and changed for decades, even though it doesn't make sense. It appears that once something appears in an authoritative glossary, people will reuse it for decades, and obsolete terms may never die out.


Additionally, the "main frame" was a Honeywell term for the large physical frame which held the CPU. History!

MT8 Small Linear Thermoelectric Actuator - Honeywell UK Heating Controls
MT8 Small Linear Thermoelectric Actuator

Could this be the perfect solution to remotely controlling individual radiators? It is thermoelectric and not motor driven making it very quiet in operation. It can also be proportionally controlled using PWM allowing finer control over water flow. It is powered so no batteries to replace.

Evohome is Noisy - please help me
Verrry long forum thread about how noisy one user finds the HRT92 TRVs from Honeywell's Evohome range.
Doesn't really get to the bottom of the problem except a general agreement that they are quieter than the competition. One user found that covering the TRV with another container made it quieter. Several interesting experiments and promised experiments which petered out.
Conclusion... suck it and see! Also a mention of the completely silent wired MT8 although that is either on or off and doesn't use proportional control. Also Honeywell Valencia valve body may be quieter (but later disproved).

Woodrow Bellamy III on Twitter: "The @Honeywell_Aero megawatt power generator on display at their pre #NBAA18 event… "
Sadly, this was to be the generator for the XV-24A LightningStrike eVTOL demonstrator, to be paired with a turboshaft engine.
