  2. Torque limiter - Wikipedia

    en.wikipedia.org/wiki/Torque_limiter

    An over-torque condition pushes the balls out of their detents, thereby decoupling the shaft. It can have single or multiple detent positions, or a snap acting spring which requires a manual reset. There may be a compression adjustment to adjust the torque limit. Many cordless drills incorporate this type of torque limiter in a planetary ...

    The Honeywell 200 was a character-oriented [1]: 70C-4S0-01n two-address commercial computer introduced by Honeywell in December 1963, [2] the basis of later models in Honeywell 200 Series, including 1200, 1250, 2200, 3200, 4200 and others, [3] [4] and the character processor of the Honeywell 8200 (1968).

  5. Zone valve - Wikipedia

    en.wikipedia.org/wiki/Zone_valve

    [2] No inherent redundancy for the pump. A zone-valved system is dependent upon a single circulator pump. If it fails, the system becomes completely inoperable. The system can be harder to design, requiring both "SPDT" thermostats or relays and the ability of the system to withstand the fault condition whereby all zone valves are closed ...

  7. Integral windup - Wikipedia

    en.wikipedia.org/wiki/Integral_windup

    Within modern distributed control systems and programmable logic controllers, it is much easier to prevent integral windup by either limiting the controller output, limiting the integral to produce feasible output, [5] or by using external reset feedback, which is a means of feeding back the selected output to the integral circuit of all ...
