Abstract: A device for abrasive machining, comprising a substantially cup shaped to rough rotatable around an axis and having an inner chamber and a disk-shaped to working element at its one axial end; and immovable holder attachable to a machine to and surrounding at least a portion of said working element at an opposite axial end at a distance therebetween so as to form a passage for passing a cooling liquid; and a helical guiding means provided in said passage so that during rotation of said tool inside said holder the cooling liquid is supplied through the substantially helical guide into said inner chamber of said tool toward said working element.

Abstract: Fine abrasive machining of a part includes providing a tool having a plurality of successive portions configured and arranged so that each preceding portion provides a coarser abrasive machining while each subsequent portion provides a final abrasive machining, and providing a relative movement of the abrasive tool relative to the part so that first a portion of the tool configured a coarser abrasive machining machines a part and thereafter a portion of the tool configured for a finer machine provides abrasive machining of the part.

Abstract: For producing a part, a wire is wound so that portions of the wire extend along one another, and the portions of the wire are connected with one another, while during the winding the wire is supported so that the wire is not wound onto a support which fills it completely.

Abstract: A precision machine tool, comprising a table which is suspended so that it is substantially a swivelable table; a driving element for driving a tood during machining of a part; and a device for orienting said table, said orienting device including at least three orienting elements, each including a plurality of rolling bodies which are brought successively into a contact with a surface of said table on which work pieces to be machined are located.

Abstract: A method of producing an abrasive tool, comprising the steps of preparing a blank of an abrasive tool including abrasing grains in a bond; placing the thusly formed blank in a container; covering the thusly formed blank in the container with at least a protective material; applying a glass material in the container so as to close the container and to form a lock which prevents penetration of an outside atmosphere through the lock into an interior of the container and at the same time allows escape of gases and contaminant from the interior of the container outside; placing the container into a heating device and providing in the heating device a temperature allowing melting of the glass material and creating the lock and also providing sintering of the blanks in the interior of the container; removing the container from the heating device after the sintering; breaking the lock and removing the sintered blanks which form the abrasive tools from the container.

Abstract: A sun visor glare reducing extension for incorporation within a vehicle's sun visor is disclosed having a three sided rigid frame capable of being incorporated within a vehicle's sun visor. The frame has a back frame member pivotally affixed to a pair of generally parallel leg segments at each end. Each leg segment forms a "U" shaped retaining channel. A glare shield slidably retained within the "U" shaped retaining channels, and is deployable in a linear manner from the edge of an otherwise conventional sun visor.
