Abstract
1416435 Life support equipment GRAVINER LTD 27 Feb 1973 [2 March 1972] 9809/72 Heading A5T Emergency life support equipment comprises personal headgear, detecting means for detecting an incipient fire hazard condition involving the wearer of the headgear, and discharge means automatically responsive to detection of the hazardous condition for discharging a breathable atmosphere into the head gear. A spray apparatus 58 located within a helmet 8 is connected to an air reservoir 12 through a pipe 10 and an explosively operated valve 14 detonated electrically by a fire-sensing means 53. The valve comprises a body 16 formed with a chamber 30 within which is located a needle 34 carried by a piston 36 connected via a frangible disc 42 with a piston 41 and explosive charge 40. On detonation of the charge, needle 34 is moved by pistons 41, 36 to pierce a diaphragm 18 permitting air to enter needle 34 and flow to pipe 10 via an opening 37 in piston 36. The charge may be detonated additionally from switch 52, a push button 48 or an inertiaswitch 50.
