Abstract: This invention relates to a fuel injection system for a ramjet engine of the type comprising a swirling combustion chamber, wherein said system comprises:at least one first injector arranged in the inner part of the corresponding air duct to send, in common with said first injectors of the other individual injection devices, fuel into a common zone of said combustion chamber adjacent said closed end and peripherally defined by said air ducts; as well asat least one second injector arranged in the outer part of the corresponding air duct, to send fuel into a specific zone of said combustion chamber located near the wall thereof, downstream of the opening of the corresponding air duct. The invention is more particularly applicable to the propulsion of missiles.

Abstract: A system for the transfer of loads from a wheeled transporter to a roller conveyor. The system includes two transfer conveyors which are arranged in alignment with a roller conveyor supplying a machine. Strips are provided on the wheeled transporter which form spaces therebetween to receive bars which project laterally from a pallet on the wheeled transporter. The pallet can be raised and lowered so that the bars can be moved onto the two transfer conveyors to facilitate transfer of the loads from the wheeled transporter to the two transfer conveyors which in turn transfers the loads to the roller conveyor or supply of the machine.

Abstract: The invention concerns new difficultly inflammable polyesteramide yarns, fibers and films.These yarns, fibers or films consist of a polymer obtained from the reaction of at least one aromatic diisocyanate and aromatic diacids, at least one of said diacids containing one or more ester groups.These new yarns, fibers and films are employed in all fields in which properties of low inflammability are desired.

Abstract: The invention concerns new difficulty inflammable polyesteramide filaments, threads, fibers and films.These filaments, threads, fibers or films consist of a polymer obtained from the reaction of at least one aromatic diisocyanate and aromatic diacids, at least one of said diacids containing one or more ester groups.These new yarns, fibers and films are employed in all fields in which properties of low inflammability are desired.
