摘要： A method of processing a lens is disclosed. A lens blank and a lens block are each provided with a structured surface having a plurality of tapered elements. The lens blank is releasably attached to the lens block by pressing the structured surface of the lens blank against the structured surface of the lens block, followed by subjecting the mounted lens blank to lens processing operations.

摘要： The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a blend of (i) a hydrocarbon resin, preferably an aromatic hydrocarbon resin; (ii) a side chain crystallizable hydrocarbon polymer or copolymer; and (iii) optionally an modifier or mixture of modifiers, preferably straight chain alcohols. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.

摘要： A concatenation of circular abrasive discs each having a layer of abrasive material on a first surface, and means on a second surface for releasably attaching said discs to a drive member. The discs are attached to two adjacent discs at opposite edges by two narrow tabs along each edge spaced by at least 0.32 centimeter (1/8 inch) along the edge and generally equally spaced on opposite sides of a center line extending between the centers of the attached discs. Also the discs are separated between the tabs and the tabs are folded to position abrasive discs in a stack within a container with each abrasive disc in the stack having its layer of abrasive against the layer of abrasive of one adjacent disc, and its means for attaching adjacent the means for attaching of the other adjacent disc.

摘要： The present invention provides a block assembly for mounting an optical lens blank onto a lens processing machine, comprising a compliant lens block with a relatively thin double-sided adhesive tape having differential adhesion. This assembly affords a very cost efficient system for attaching a lens blank to a lens processing machine. In contrast to traditional thick adhesive pads, the tapes of the present invention do not suffer from shear displacements which may cause processing errors or inaccuracies. In addition, the double-sided adhesive tapes of the present invention achieve greater adhesion to the lens block than to the lens. This feature promotes and ensures a "clean" removal of the tape from the lens when the block is deblocked. The present invention also provides a method for mounting an optical lens blank onto a lens processing machine. This method comprises the steps of: disposing a compliant block assembly in close proximity to an optical lens blank (the block assembly comprising a base structure having a compliant receiving surface adapted to conform to a surface on an optical lens blank to be processed in a lens processing machine and a mounting means for mounting the block onto a chuck of a lens processing machine, wherein at least a portion of said compliant receiving surface is covered with a thin double-sided adhesive tape having differential adhesion); adhesively attaching the optical lens blank to the compliant block by applying the block to the optical lens blank with sufficient pressure to conform the receiving surface to the surface of the optical lens blank while the adhesive tape joins the block and optical lens blank together; and mounting the block and the adhesive tape joined optical lens blank onto the lens processing machine.
摘要翻译：本发明提供了一种用于将光学透镜毛坯安装到透镜加工机上的块组件，其包括具有差的粘合力的相对薄的双面胶带的柔顺透镜块。该组件提供了将透镜毛坯附接到透镜加工机器的非常成本有效的系统。与传统的厚粘合垫相反，本发明的带不会受剪切位移的影响，这可能导致加工误差或不准确。此外，本发明的双面胶带比透镜实现对透镜块的更大的粘合性。当块被解锁时，该特征促进并且确保从透镜中去除胶带的“干净”。本发明还提供一种将光学透镜毛坯安装到透镜加工机上的方法。该方法包括以下步骤：将柔性块组件设置在光学透镜毛坯附近（该组件包括具有柔性接收表面的基座结构，该基座结构适于符合待透镜处理的光学透镜毛坯上的表面）加工机和用于将所述块安装到透镜加工机的卡盘上的安装装置，其中所述柔性接收表面的至少一部分被具有不同粘合力的薄双面胶带覆盖）; 将光学透镜毛坯粘合到柔性块上，同时将粘合带将块和光学透镜毛坯粘合在一起，同时以足够的压力将该块施加到光学透镜毛坯上以使接收表面与光学透镜毛坯的表面一致; 并将块和胶带连接的光学透镜毛坯安装到透镜加工机上。
