Topic: Who made Falconnier glass bricks embossed "DEP FRANCE / BELGIQUE"?

[ian.macky]

I'm updating my Falconnier glass brick page (due to a contact from a Russian enthusiast, who sent me pics of both Polish and Russian manufactured versions used in Saint Petersburg), and it occurs to me that I don't know who made the most common of his bricks!

The usual embossing seen is "DEP FRANCE / BELGIQUE" which I always assumed just meant "Made in France or Belgium", but in trying to pin it down, I find I can't actually identify the acronym or abbreviation "DEP" at all.

So my two questions are:

Who made these?

What does "DEP FRANCE / BELGIQUE" mean exactly?  Is DEP an abbreviation or acronym or company mark??

Am feeling ignorant since this is such an obvious question that should have been asked long ago.   

I also found a new 8-page Falconnier catalog from Glashüttenwerken Adlerhütten, ca 1905, which I have scanned and put online:
Here's the 27MB 300DPI PDF: http://glassian.org/Falconnier/Catalog2/falconnier_adlerhutten_catalog_1905.pdf

Thank you!

If it's the same as you find on some bisque head dolls' don't ask why I know this  it means registered, it's from the word deponiert I believe.

Perhaps déposer (to file a patent)?  That would work, but seems odd the body would note it's registered in France/Belgium, while the seal usually says "D.R.P / 41773" -- D.R.P. is Deutsches Reichspatent, non?

An online search for "DEP FRANCE" turns up almost no likely hits; also seems odd that this would not be a more common embossing on patented glassware, if that's what it means.
