Boeing 757/767 with over wing exits as opposed to a 4th door aft of the wing were fitted with a pyrotechnic actuator which faired #6 and 7 spoiler so that the o/wing route to the slides from the doors was clear. It was activated when the overwing doors were opened and whilst fluid was ported to return the firework knocked down the panel.

Accumulators are used for energy storage on almost every a/c I have ever worked on. Usually for Brake systems but also for HMG's, LAF's and others.

Yes good riddance to bad rubbish the LAF system in the 'bus was a complete waste of space and a maintenance intensive (i.e. costly item). Not on the newer 320's or the 321's and 319's.
