Patent GB-1882-5251
The specification says that air (not water) may be used to cool the gas engine, and that a pipe shaped like an Archimedean screw worked by the engine to assist cooling (says Neilson, p 15, as well as the Abridgment, which also classifies this patent under GB 7, "Air and gas engines").
Koch is the inventor and P. Jensen is probably a patent agent, per Neilson p70 and 72
"Feathering paddle-wheels are arranged in recesses in a cigar-shaped balloon, the said paddle-wheels being capable for revolving at different speeds for steering purposes."
Filed the same year as Patent DE-1882-23658, and in fact just a few days afterwards, yet these patents are not the same: the German patent deals only with the network of material connecting parts of an airship, while the British patent describes a whole design, perhaps inclusive of the German filing. The final part of the airship's description in the Abridgment might be the overlap:
A series of interlacing airtight silk tapes, united to the balloon some distance below its centre, and having their ends connected with the car, is used instead of the usual network. This preserves the material and keeps the surface smooth, and may be used as a parachute if necessary.
