A preferred process for degassing a mold piece includes inserting the mold piece into an internal volume within a canister, sealing the internal volume, drawing a vacuum in the internal volume, and introducing into the internal volume a gaseous fluid suitable for degassing the mold piece.

Devices and processes for performing degassing operations

A method for predicting a tool point response of a spindle-holder-tool assembly to be used for high-speed machining applications is provided. The method includes determining direct and cross displacement-to-force receptances of a standard holder clamped in the spindle. The method also includes determining direct receptances at a free end of the standard holder based upon the determined direct and cross displacement-to-force receptances of the standard holder. Additionally, the method includes performing an inverse receptance coupling to simulate a decomposition of the standard holder into multiple subassemblies, the subassemblies including a spindle-holder base subassembly and an extended holder subassembly. The method further includes determining spindle-holder base subassembly receptances based upon the simulated decomposition of the standard holder.

System and method for tool point prediction using multi-component receptance coupling substructure analysis

A high frequency flexure-based dynamometer for measuring vibrations to use in determining cutting forces in a tool is disclosed. The dynamometer device may operate within a pre-selected high frequency range while measuring cutting forces less than about 1 N. The dynamometer may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer may include a workpiece mounted to one of the two flexures and a one or more precision accelerometers mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.

In a processing facility comprising a plurality processing stations each for automatically conveying products in various stages of production for controlled processing, an intelligent product transfer and conveyance system that enables uninterrupted processing of only products determined as having passed a first inspection process at an upstream processing station. The intelligent product transfer and conveyance system for a processing facility ensures a continuous flow of a plurality of good products at sufficiently high speeds from an inspection process to subsequent stations for subsequent individualized packaging. The processing facility may comprise a contact lens manufacturing line for manufacturing spherical or toric type ophthalmic contact lens products.

System and method for intelligent lens transfer

A method for tracking multiple SKUs of ophthalmic devices in a manufacturing line, comprises the steps of: assembling first molding devices, at least one of the first molding devices having an identification device, such as, a bar-code or an inductive transmitting/receiving device; reading the identification device of the first molding devices; forming first molded parts using the first molding devices; providing a plurality of carriers, the carriers having carrier indicators; transferring the first molded parts to at least one of a plurality of carriers; reading the carrier indicator of the carrier carrying the first molded parts; and storing in machine-accessible memory the information associated with the identification device of the first molding devices and the information associated with the carrier indicator of the carrier carrying the first molded parts.

Contact lens container

This invention provides a blister pack comprising a base and a cover, wherein said base comprises a recess which houses a contact lens and solution, wherein the thickness of the material of said recess is less than 0.75 mm, and said recess houses less than 0.75 ml solution.

Primary package for contact lens

A method and a support for supporting a package in a steam sterilizer, featuring support members configured and positioned to support only at least a portion of at least two opposed side edges, but not a side face, of the package. A diamond shape is particularly preferred for the support members as, when rotated at an angle, its facets provide line contact with appropriate side edges of the package.

Method and support for supporting packages only at their edges during

A method of and apparatus for employing a surfactant which is provided in order to assist in the release from each other of mold components of a multi-part mold employed in the molding of polymeric articles; for instance, such as a hydrophilic contact lens, upon completion of the molding process for the polymeric articles. The surfactant is applied in the form of a film or coating on surface portions of one of the mold components in order to facilitate the disengagement between the mold components during demolding, and the removal of excess polymeric molding material adhesively deposited on surfaces thereon.

Method and apparatus for applying a surfactant to mold surfaces

An apparatus and a method for removing a liquid from a container having a bowl and a flange, the bowl holding the liquid and containing a hydrophilic ophthalmic lens, wherein there is provided a nozzle with a central face and a shoulder around the periphery of the face. The shoulder has a sealing means which is sized to fit on the flange of the container, where it forms a sealed volume above the container bowl, this volume including the volume of the bowl itself. The central face has through it at lease one fluid entrance passage and at least one fluid exit passage arranged so that the flow is distributed substantially symmetric about the center axis of the lens. The apparatus includes a lens retainer which resiliently urges the lens into engagement with the bowl so that when the purging fluid is introduced into the sealed volume, there is no migration of the lens. There is connected to the entrance passage a source of purging fluid that has a pressure and flow sufficient to remove substantially all the liquid through the exit passage.
