I've red about this way of requining in russian (former - soviet) journal
"Pchelovodstvo" ("Beekeeping"). It's still published.
 
Author (comershial beekeeper, 100+ hives) said: It's simple, close to nature
and low expensive way. He used it to change quins in age of 2 years. Hi used
1 quin-cell in age of 2 days before quin apiarence.  Without any cage the
cell was putted between frames in upper super. 2 days after author checked
the cell. If it was punktually open from one end he decided that requinning
has taken place (author said - 70%+). If the cell has been nibbled by bees
(from one side) he repeat the attempt. Second attempt was sucsessfull in
app.15-20% In other cases author presupposes that bees had preffered old
quins.  Of course, laing must be checked later!
