摘要： A lap blank and holder assembly includes a lap blank having two spaced apart flat surfaces separated by a given thickness and formed from a material capable of compressing about a member inserted into it. The holder has a projection extending outwardly from a front face thereof and is inserted into the material making up the lap to secure it against rotational and shifting movement while being cut in a surfacing machine. This arrangement further allows the assembly to be placed as an assembly in a finishing machine for subsequent polishing of a cut lens surface in a polishing procedure.

摘要： A cutting machine has a planar support surface for supporting a work piece and a carriage supported for movement above the planar surface. The carriage independently supports a vacuum shroud having a body portion partially defining a chamber and at least one duct portion outwardly extending therefrom. The body portion is adjustably fixed to the carriage through a connecting flange which extends upwardly from the body portion. The body portion also has a base portion that supports a resilient layer and a contact elements, the layer when it is compressed, exerts a force between the base portion and the contact element contacting the work piece supported on the planar support surface.

摘要： A work locating system having temperature and other compensation capabilities wherein the work member is mounted for controlled movement with respect to the work tool. Two sets of two laser interferometers are utilized to generate distance measuring light beams such that the beams of each set are coaxial and the beams of the respective sets are orthogonal and intersect at the work tool reference axis to thereby instantaneously and continuously determine the location of four reference points on the work member and compensate for all expansions or contractions of the work member or changes in the laser measuring system during the programmed work operation.

摘要： Ophthalmic lens wafers for forming a composite lens are provided wherein each front lens wafer has a front registration pattern formed on its peripheral edge, and each back lens wafer has a back registration pattern formed on its peripheral edge which is different than the front registration pattern. If the ophthalmic lens wafers include optical axes, such as horizontal axes for multi-focal segments or astigmatism axes, each registration pattern is oriented at a predetermined angle relative to the respective optical axis for facilitating alignment of the optical axes relative to each other when forming a composite lens in accordance with a particular prescription. Each lens registration pattern may be formed by a pair of notches on the peripheral edge of the wafers, or by a pair of lobes on the peripheral edge of the wafers. A receiver is also provided for holding and registering the ophthalmic lens wafers when laminating or otherwise forming a composite lens. The receiver defines a stepped recess formed by a plurality of circular-shaped steps, and each step includes at least one registration pattern which matches the registration pattern of either a front or back lens wafer, but not both. The registration patterns of the receiver may be formed by key pairs which are shaped and positioned relative to each other to mesh with a respective lens registration pattern. The key pairs may likewise be retractable for generating different registration patterns to receive different wafer types on the same step of the receiver. Alternatively, the registration pattern of the receiver may be formed by recessed surface areas for receiving corresponding lobes on the lens wafers. The recessed surface areas may likewise be formed by retractable surface sections for generating different registration patterns to receive different wafer types on the same step of the receiver.

摘要： A lens or lap blank surfacing machine, for use in making eyeglass lenses, and related surfacing method and rotary cutting tool, is one wherein the rotary cutting tool is moved point by point over the entire extent of a face of the blank to form a new face surface on the blank with the movements of the tool and blank relative to one another being controlled in three coordinate directions by a computer controller to give the formed surface a shape related to a given eyeglass prescription or similar specification. The rotary cutting tool has a number of peripheral zones surrounding its rotation axis with at least one of the zones having a fine cutting characteristic and with at least one other of the zones having a coarse cutting characteristic. In the movement of the tool and blank relative to one another, the tool is held so that its fine peripheral zone engages and cuts away blank material immediately adjacent the desired surface and so that the coarse peripheral zone engages and cuts away blank material to a depth not quite reaching the desired surface thereby leaving a thin layer of residual unwanted blank material which is cut away by the fine peripheral zone of the tool at a later time, this permitting the creation of a face surface of desired shape and fine surface finish.

摘要： A method and related system and article provides a lens blank and block assembly capable of being mounted in any of a surface generating machine, a finishing apparatus and an edging machine without requiring re-blocking of the lens in order to compensate for axis shifts. The method and associated system utilizes a controller which takes data inputted to it in the form of prescription information and a frame opening shape and converts it into two sets of machine operating data together used by a computer to allow the surface to be generated on the blank so as to be readily shaped edgewise according to a selected frame pattern by simply the mounting blank and block assembly in the edging machine thereafter. The blank is separated from the block assembly and readily inserted into a selected glass frame.

摘要： An ink jet printing system has a low aspect ratio cylindrical drum adapted to support a sheet of material to be printed by a computer controlled printing head of a plurality of pigmented inks. The drum is preferably of approximately the same diameter as its axial length, is made up of at least two spoked wheel assemblies consisting of several arcuate wheel segment subassemblies that are joined together and held in place by a corregated skin covered with a fiberglass layup to provide a smooth cylindrical surface onto which the sheet material is spread. A clamping device is provided for tensioning the sheet material as it is rotated past a carriage carrying the printing head and affording two relative movement directions as between the printing head and the sheet to be printed for these differently colored printing inks.
