propelling gas in such a manner that forces generated by the
propelling gas cause the flexible barrier to deform into sliding

the purpose of providing a seal which prevents leakage of the
propelling gas past the projectile. Independent claim 1 is
further illustrative of the appealed subject matter and reads as
