20120017451 | SHARPENER, ESPECIALLY FOR A COSMETIC OR PHARMACEUTICAL PENCIL - A sharpener for sharpening a pencil, in particular a cosmetic pencil, is especially suitable, when used correctly, for producing a particularly uniform outer jacket edge in the region of the pencil tip. The sharpener includes a sharpener body, in which a pencil guide channel is provided. The pencil guide channel has a circular cone-shaped channel section and opens out in a pencil inlet opening on the outer side of the sharpener body. A paring blade is positioned tangentially to the lateral surface of the channel section. The paring blade serves to pare off a pencil tip, which includes a front lead section and a rear outer jacket section. A shaping tool cuts a shoulder into the pencil tip, the shoulder being set back in relation to a circular cone-shaped enveloping surface of the pencil tip. The shaping tool is arranged relative to the pencil guide channel to insert the shoulder into the transition between the lead section and the outer jacket section of the pencil tip. | 01-26-2012 |

20090065545 | METHOD AND DEVICE FOR PRODUCING GLASS PANES OF ANY DESIRED CONTOUR FROM SHEET GLASS - A method for producing glass plates of any desired contour from sheet glass, comprising the following steps: scribing scribe lines into a least one face of the sheet glass along the contour down to a depth, using a cutting device, and positioning the glass plate on a support. The method is further characterized in that a defined force F is applied to the sheet glass so that it breaks along the scribe lines, said break extending through the entire thickness of the sheet glass. The flat glass may be sandwiched between two flexible plates prior to being placed on a base pad and being subjected to the breaking force. | 03-12-2009 |
