forces for each type of vehicle to be arrested, such
as different types of airplanes, motorcars or the

serves to reduce the high pressure in pressure
container 5, to a suitable constant working
pressure. . . .
The air in the system may, after a completed
working period, be bled out through the bleed
opening in the valve 16 . . . . . . . Between
said pressure reducing valve 8 and the brakes 4 a
conduit 11 is interconnected, said conduit being
provided with a valve 12 having an operating lever
for closing and opening the same. . . .
The conduit 11 is also connected to a central
channel 15 within the brake housing. Said channel
15 is adapted to conduct the compressed air to the
lower one 4' of said brakes and serves at the same

having such a selected volume as to provide for a
uniform increase of the braking action until full
braking action is obtained after a suitable period
of time [column 1, line 62, through column 2, line
26].
