    Abstract: The invention relates to a device for fastening a holding part on lenses, of the type comprising, for placing a gripping block (12) onto a spectacle lens (10) waiting on a stage (11), a holding arm (16), designed for receiving the gripping block (12) removably, and a carriage (20), on which the holding arm (16) is mounted pivotably between two positions and which is itself mounted movably between two positions along a path in the course of which the holding arm (16) is presented automatically in line with the stage (11). According to the invention, since the carriage (20) is at least partially mounted movably in a straight line in a first direction (D1), the pivot axis (34) of the holding arm (16) extends in a second direction (D2) orthogonal to the first, and between this carriage (20) and this holding arm (16) is inserted a transmission (30) capable of causing the holding arm (16) to change from one of its positions to the other when the carriage (20) changes itself from one of its positions to the other. The invention is used especially in centring devices.

    Abstract: The invention concerns a device in which a blocking arm (13) is mounted on a carriage (15) in such a way that it pivots between a raised loading position and a pivoted fitting position. According to the invention, between the blocking arm (13) and the carriage (15) there are pawl-type engagement means (38, 40) capable of a releasable locking of this blocking arm (13) on this carriage (15) when it is in the pivoted fitting position. Application to the blocking of any grasping stud on a spectacle lens workpiece.

    Abstract: A device for fitting a handling block to an eyeglass lens to which the handling block adheres temporarily includes a receptacle into which the handling block is push-fitted. An ejector system associated with the receptacle facilitates disengagement of the handling block from the receptacle after it is fitted to the lens. This system is operative outside the receptacle and engages operatively on the eyeglass lens concerned. It comprises two ejector fingers movable parallel to the axis of the receptacle against return springs.

    Abstract: An opthalmic lens centering device comprises a frame on which is a translucent first support plate which receives an opthalmic lens to be centered. There is a frosted screen at the base of the first support plate. A projector system above the first support plate projects an image of the ophtlalmic lens onto the frosted screen. A first observation channel and an opening in the frame enable an operator to view the frosted screen. A second support plate receives a template with which the opthalmic lens is to be compared. A second observation channel in conjunction with the same opening in the frame enables the operator to view the second support plate. The first and second observation channels have a common emergent section of which the opening in the frame forms part. There is a recess in the frame, opening onto its front surface, by means of which the second support plate is disposed at the front of the frame.

    Abstract: The invention relates for example to measuring the mounting height to be adhered to when fitting a corrective lens on to a glasses frame. The apparatus according to the invention comprises for this purpose a feeler 17, to which is connected an index, an observation unit 20, which is mounted movably, and a measurement scale, which, itself also mounted movably, opposite the aforementioned index, is linked in movement with the observation unit 20, the said observation unit 20 being adapted to allow observation of corneal reflection on the eye of the patient in question. Application not only to measuring a mounting height, but also pupillary distance.
