Abstract: The invention provides a showcase having at least two glass doors, a first door being fastened to a front ferrule and a second door being fastened to a rear ferrule, each of the ferrules moving along a respective rail, said locking device comprising a lock for locking the two doors together, wherein the showcase includes a locking device comprising a slider mounted to move in said front ferrule transversely relative thereto, and having a rotor of the lock installed thereon, wherein said rear ferrule includes an opening that comes into line with said rotor in a position for locking the two doors together, and that is suitable for receiving a bolt mounted at the end of said rotor, and wherein said slider includes a relatively flat face plate coming substantially flush with said ferrule in the locked position of said doors.

Abstract: The apparatus has a measuring roller (10, 10i) which comprises independent peripheral regions deformable by compression. The sensors (13, 13i) are fixed to and associated with the deformable peripheral regions of the roller in order to detect the deformation thereof under the effect of the strip and to provide signals in dependence on the deformation. A utilization circuit receives the signals of the sensors in order to derive data and control signals therefrom.
