2. Active tip-clearance control - Wikipedia

   en.wikipedia.org/wiki/Active_tip-clearance_control

   The thermal effects take longer to stabilize at a steady temperature, ie to give an unvarying tip clearance. This transient condition which gives a minimum clearance is known as a pinch point. The setting of the clearance when the engine is built such that the blade tips don't rub the stationary shrouds in the turbine case at a pinch point ...

3. Power system protection - Wikipedia

   en.wikipedia.org/wiki/Power_system_protection

   Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network.

4. Thermal cutoff - Wikipedia

   en.wikipedia.org/wiki/Thermal_cutoff

   A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).

5. Brownout (electricity) - Wikipedia

   en.wikipedia.org/wiki/Brownout_(electricity)

   Commutated electric motors, such as universal motors, will run at reduced speed or reduced torque.Depending on the motor design, no harm may occur. However, under load, the motor may draw more current due to the reduced back-EMF developed at the lower armature speed.

6. Clearance Divers Life Support Equipment - Wikipedia

   en.wikipedia.org/wiki/Clearance_Divers_Life...

   The CDLSE (Clearance Divers' Life Support Equipment) is made by Divex in Aberdeen, Scotland. [1] It is an electronic closed circuit rebreather designed to be silent and non- magnetic . It allows diving to 60 metres (200 ft) using air as diluent , or up to 120 metres (390 ft) using heliox and trimix .
