摘要： An elongated handle with an internal supply of fresh dental floss and a flossing head including a fork provides oral hygiene. A fresh section of floss is advanced by a one-touch arrangement which concurrently relegates spent floss to a separate take-up reel. The fresh floss spanning the tines of the fork is kept taut at all times as a result of various special expedients including a differential spool and drum and a rack and pinion floss locking arrangement. When the supply of fresh floss on the bobbin is exhausted, the device is discarded.

摘要： A precision tool holder for precisely positioning a single point cutting tool on 4-axis lathe, such that the center of the radius of the tool nose is aligned with the B-axis of the machine tool, so as to facilitate the machining of precision meso-scale components with complex three-dimensional shapes with sub-μm accuracy on a four-axis lathe. The device is designed to fit on a commercial diamond turning machine and can adjust the cutting tool position in three orthogonal directions with sub-micrometer resolution. In particular, the tool holder adjusts the tool position using three flexure-based mechanisms, with two flexure mechanisms adjusting the lateral position of the tool to align the tool with the B-axis, and a third flexure mechanism adjusting the height of the tool. Preferably, the flexures are driven by manual micrometer adjusters. In this manner, this tool holder simplifies the process of setting a tool with sub-μm accuracy, to substantially reduce the time required to set the tool.
