Abstract: A fluid dispenser device includes a fluid tank, a dispensing pump (10) operating without air intake, a turret (20) supporting and fixing the pump (10), the turret being fixed on the tank by a fixing ring (30), the device being characterized in that at least a portion (21) of the turret (20) is made of a plastics material that is permeable to air.

Abstract: An obturation device for the disposable bag (1) of a vacuum cleaner, the bag (1) having a rigid area (1a) in the vicinity of a closable filling inlet, in order to fix the bag (1) to a frame part (13) of the vacuum cleaner, as well as a flap (5) for closing the bag (1) , the flap being displaceable by rotation between an open position and a closed position of the filling inlet in the extension plane of the rigid area (1a). The closing flap (5) is mounted in the rigid area (1a) which is provided with a profiled perforation (4a) whose shape and contour form a guiding structure (4) within which the closing flap (5) can move. Application to disposable bags for vacuum cleaners.

Abstract: A device for fastening a holding part on an eyeglass frame placed on a plate comprises an arm adapted to receive removably the holding part and a carriage on which the arm pivots between a raised loading end position and a lowered fitting end position. The carriage is mobile on a frame in a straight line between a retracted rest end position and an advanced end of travel position. A transmission system operative between a drive system and either the arm or the carriage is such that, at least when the carriage is in the vicinity of its advanced end of travel position, the arm is in its retracted fitting position. A locking device is operative between the arm and the carriage to lock the arm releasably to the carriage when in its lowered rest position.

Abstract: A support device for eyeglass frames whereby the contour of one or both rims or surrounds of the frame can be read comprises a plurality of retaining means on a plate and on a flap pivoted to the plate. The retaining means are adapted to hold an eyeglass frame above a hole in the plate. The flap is pivoted to the plate and its inclination relative to the plate is adjustable.

Abstract: A device for fastening a holding part on an eyeglass lens placed on a plate comprises an arm adapted to receive removably the holding part and a carriage on which the arm is able to pivot between a loading and offloading position and a fitting position. The carriage is mobile on a frame between a rest position and an end of travel position over a path on which the arm is brought into alignment in the fitting position with the plate. The carriage is at least in part adapted to move in a straight line in a first direction controlled by a guide fastened to the frame and the pivot axis of the arm is in a second direction orthogonal to the first direction. A belt and gear transmission is operative between the carriage and the arm to move the arm from one end position to the other.

Abstract: A pattern simulator is for use with a grinding machine, especially a machine for grinding eyeglass frames, the machine comprising a grinding wheel support shaft, a pattern support shaft coplanar with the grinding wheel support shaft and a box member carrying the pattern support shaft and adapted to pivot relative to the grinding wheel support shaft. A bearing key in the grinding machine is adapted to support a pattern mounted on the pattern support shaft, an end of which overlies the bearing key. The pattern simulator is adapted to conjugate the distance between the grinding wheel support shaft and the pattern support shaft with the angle of rotation of the pattern support shaft on itself relative to a reference. The pattern simulator constitutes a self-contained mechanical entity and comprises a mounting piece adapted to be fitted to the pattern support shaft of the grinding machine and keyed to it to rotate with it.

Abstract: A device for reading contours, as of eyeglass frames, comprises a feeler adapted to be applied to an article in order to read its contour. A carriage supports the feeler and is movable to-and-fro on a guide. A drive motor moves the carriage on the guide. A floating mounting is disposed between the feeler and the drive motor.
