Patent FR-2555785-A1 (FR)
Inventor: FUMEI GIANCARLO JOHN
IPC: G09F3/02
Filed: 1984-11-27
Abstract: The present invention provides, without the drawbacks accompanied by the use of hot melt adhesives, an attractive, easily recycled labelled container (8), and a method of making same. The container has a solid polymer label (10) on its underside (22) that is adjacent the container when applied, which is provided with a finite area (65) on its leading edge (25) and a finite area (66) on its trailing edge (27), by applying thereto a solvent for the polymer in each of the finite areas, the finite areas (65, 66) comprising a viscous tacky solution of the polymer in the solvent, the solidifying solution being sufficient to tack and bond the lavel (10) to container (8) during wrapping. After the label is wrapped around the container, the bond between the container and label becomes weaker as the solidifying solution hardens so that later the label (10) can be easily and cleanly stripped from the container (8) for recycling. The label can be a co-extruded plastics label having a first solid polymer layer (20) and another solid polymer layer, the finite areas (65, 66) being applied to the first solid polymer layer (20).

Patent WO-8607210-A1 (WO)
Title: Anti micro-breaking device
Inventor: CERCLE LOIC
IPC: H02J9/06
Filed: 1985-05-20
Abstract: The device enables to avoid electric micro-breakings. It is comprised of a double receiver supply, one normal supply and another emergency supply. The normal supply passes through a conductor wire coil before getting to the receiver. This normal supply directly controls the base of a transistor which provides for the switching on of the emergency supply network upon the occurrence of a micro-breaking, and this before the micro-breaking has run past the length of the coil. The receiver is therefore always supplied. The device is essentially intended to be fitted on apparatuses which are sensitive to micro-breakings, for example random access memories of computers.
