Gevaert Diaversal process?

[bdial]

I have a "Diversal process by Gevaert" chemical processing kit.
It consists of three bottles labeled;

1 Developing solution
2 Reversal solution
3 Toning solution

The box is labeled "Revere", and states that it's manufactured by Edwal.
The chemical kit was in another box labeled "Revere Cine Graphic Developing kit" which lists that it contains chemicals, trays, measuring cups, enlarging paper, sponge, easel and "special enlarging bulb". Aside from the trays and possibly the chemicals, none of that stuff is in the box.

The kit has no instructions or any other information.

From results in Google it was apparently a process for making prints from positive movie film, and also used "Diaversal paper". There are also several hits related to printing x-ray images

Does anyone know anything about the process?
I may experiment with the stuff and see what happens, I know it's highly likely that the chemicals are no good. But, since I've got nothing else to do with it, I figure I might as well try it out. Before I start blindly, I'd like to know if anyone knows anything about the kit or process.
TIA

I found a Google Books hit from a 1950 issue of Popular Science magazine.

It says the Diaversal paper is coated with two emulsions, the top emulsion makes a negative print (from a positive), and is developed normally, then the paper goes into the reversal solution which forms a positive image in the second layer by diffusion. Then the negative layer is washed off, and the remaining positive layer is toned to get it to it's full tonality.
Sort of like the Polaroid process in a darkroom.

Sounds a lot like the old 'diffusion transfer' process used in graphic arts.

As Nicholas already indicated it belongs to the Diffusion Transfer Reversal processes, more precise silver salt diffusion, and was introduced in 1947.

But in contrast to the more known processes it is a mono-sheet process and there is no peeling-off of the negative but the negative layer is washed/rubbed off.
