This is somewhat akin to Patent HU-1908-46199, though the Hungarian patent is rather more elaborate. Both include the situation of the propellers relative to the overall layout of the airship. Patent DK-1908-11943 and Patent HU-1908-46199 are identical, and seems to indicate a consideration of per se lift principles in the airship design. Patent DK-1908-12414 is is an addition patent to Patent DK-1908-11943 and it specifically adds wings. This French patent focuses more on propellers in the context of the frame relative to the chassis, and all of this may be applicable to a relatively traditional airship. This may be a step removed from the patent family.
