I once came across a leader-belt paper processor (was it Durst Epsom? I don't remember) that had a bag-floater - a bag, filled with (I think) water made of Saran, a plasticised PVC like cling film but thicker. They had a roll of it and capped it with a nylon cable tie. Water has a SG slightly lower than developer, so it floats. The bag pushed the leader belts against the tank wall. They had a tray to store it when the processor was in use. That would fit nicely in a slot processor, wouldn't it?
They used Kodak chemistry until Champion pointed out that their developer did not precipitate oxidised CD3 ('tar') because they added antifreeze to the formulation. Is that ethylene glycol?
