A temporary suspension element comprises a rectilinear guide with a threaded end, and a catch which can swing between a guiding position and a retaining position. The element can temporarily replace screws that attach a structure under a support, during the attachment or disassembly of said structure. The attachment and the disassembly of the structure can then be performed by a single operator.

Temporary suspension element

A method of transferring a portion of a functional film () onto a substrate from a base plate () comprises the formation of a groove (S) which passes through the said functional film and also a separating film () placed between the functional film and the base plate. A portion () of the separating film is then detached from the base plate with the portion of the functional film. The portion of said separating film protects the portion of the functional film in the rest of the method. According to one improvement, the portion of the functional film which is detached from the base plate comprises a useful portion () and a margin () that are connected together by the portion () of the separating film. The useful portion () of the functional film may then be gripped and handled via the margin ().

The installation includes elements for the temporary injection of inert gas; and at least one individual and autonomous casing () provided with a window () and including receiving elements for a support () carrying an ophthalmic lens (), and sealing elements () adapted to form around the ophthalmic lens () a sealed enclosure, that enclosure including a non-return inlet member adapted to cooperate with the elements for the temporary injection of inert gas.

Method of manufacturing a photochromic molded article

A translucent synthetic material article such as an ophthalmic lens comprises a plurality of well-shaped cells, some of which have at least one upstanding projection on their bottom walls. The projection have a height between 1/5 and 1/1 the cell depth and are upwardly tapering and wedge-shaped. The plurality of cells are arranged in rows and columns to define a matrix. When the translucent article is illuminated, the well-shaped cells with upstanding projections display enhanced contrast compared with such cells without upstanding projections, thereby producing an identification marking or the like.
