  • Publication number: 20200276684
    Abstract: A method of preparing a lens blank for a further operation of surfacing to transform the lens blank into a surfaced lens for further transformation into a lens having a lens shape, the operation of surfacing including processing the lens blank so that the surfaced lens exhibits a crib diameter, the method being implemented using a processing module and comprising: based on input data (ID) which define the lens shape, defining a temporary crib diameter (Dtemp) so that said temporary crib diameter satisfies a set of constraints which includes at least: a first constraint whereby the temporary crib diameter (Dtemp) is large enough for the surfaced lens having said temporary crib diameter to be suitable to be processed into said lens, a second constraint whereby the temporary crib diameter is large enough for the surfaced lens having said temporary crib diameter to include a plurality of reference points defined on the lens blank and which together identify an optical center of the lens, choosing the crib diamete

  • Patent number: 10598144
    Abstract: Embodiments of the present invention generally relate to a runner unit of a tidal power plant, and more particularly to a device for reversing a blade of the runner unit. The device according to the embodiments is lighter and more efficient with respect to known solutions which involve articulated mechanisms as it is based on a reversing servomotor including an annular piston which acts on the blade to be reversed.

  • Publication number: 20200087778
    Abstract: Vapor deposition apparatuses and methods for coating a substrate with at least two functional coatings that include a hydrophobic coating are described herein. Some embodiments include a vapor deposition apparatus with at least a first evaporator and a second evaporator, where the evaporator configured to apply the hydrophobic coating is raised above the other evaporator and is thus closer to the substrate. Others include methods of coating a substrate with such evaporators and different distances. Embodiments of the present disclosure can be useful for coating eyeglass lenses. Still others are disclosed.

  • Patent number: 9200712
    Abstract: This valve is integrated into a fluid distribution network and enables selective interruption or authorization of the circulation of a fluid. The valve includes a fluid blocking member driven in rotation by an actuator device of the valve and at least one journal, a hollow body inside which the blocking member is mobile and which defines at least one bore for receiving the journal, and a bearing disposed around each journal and inside the bore of the body enabling support of the journal and guidance thereof in rotation relative to the bore, thereby centering the journal. The valve further includes a device for immobilizing and sealing for maintenance the journal relative to the body of the valve. This immobilization device is disposed on the same side of the bearing as the internal volume of the hollow body and is maneuverable via the bearing to go from a non-clamped first configuration to a clamped second configuration in which it immobilizes the journal in the bore and vice versa.

  • Patent number: 4259121
    Abstract: A refractory cement with outstanding mechanical properties contains 10 to 30 parts by weight of C.sub.4 A.sub.3 S clinker and 70 to 90 parts by weight of an aluminous clinker including 30 to 75% CA. This cement may be prepared by either grinding said clinkers to a specified fineness and then mixing the same, or by grinding said clinkers simultaneously and jointly to said specified fineness. The novel double clinker cement allows concrete with considerably improved refractory and mechanical properties to be prepared, as compared to the corresponding products known up to now.
