Patent number: 7585139Abstract: The boring tool has a tool body (2) on which a tool carrier (10) is mounted in a radially adjustable manner. A setting member (42) serves to set the boring diameter. A drive mechanism converts a rotation of the setting member (42) into a displacement of the tool carrier (10). The drive mechanism has a differential spindle (13) which converts a rotation of a graduated disk (26) into a displacement of the tool carrier (10) for the fine setting of the boring diameter. The differential spindle (13) is mounted in a bore (51) of the tool carrier (10) and extends at right angles to the rotation axis (A).Type: GrantFiled: April 26, 2006Date of Patent: September 8, 2009Assignee: Heinz Kaiser AGInventors: Rudolf Stadelmann, Ralph Stadelmann, Ernst Hänggi

Patent number: 7407349Abstract: The boring tool having a basic body (2) in which a tool bit (27) is arranged which has a cutting edge (29) at a front end (27b). The basic body (2) has an opening (3) in which the tool bit (27) is pivotably mounted. Setting means (7) serve to set the pivoted position of the tool bit (27) relative to the basic body (2). Means (16) serve to fix the tool bit (27) in the set pivoted position. The tool bit (27) is pivotable about a pivot point (P) which is essentially neutral in terms of unbalance. The tool bit (27) is preferably connected at a rear end (27a) to a radially adjustable slide (7). The slide (7) can be finely adjusted radially, for example with a micrometer screw (9).Type: GrantFiled: July 15, 2005Date of Patent: August 5, 2008Assignee: Heinz Kaiser AGInventors: Heinz Kaiser, Ernst Hänggi, Ralph Stadelmann

Patent number: 7281888Abstract: The tool exhibits a first tool part (2) and a second tool part (3), which possess a common axis of rotation (A). The first tool part (2) is provided with an alignment pin (4) and exhibits at its root an annular surface (5). The second tool part (3) possesses an axial bore (7) to receive the alignment pin (4) and an annular surface (6), which is capable of being tensioned against the annular surface (5) of the first tool part (2). Tensioning structures (8, 9, 10) serve for the axial tensioning of the two tool parts (2, 3) to one another. The tensioning structures (8, 9, 10) exhibit three retaining screws (8, 9, 10) arranged distributed around the periphery of the second tool part (3), which retaining screws are each screwed radially into a threaded bore (12, 13, 14) of the second tool part (3) and each engage in a radial bore (21, 22, 23) of the alignment pin (4).Type: GrantFiled: February 9, 2007Date of Patent: October 16, 2007Assignee: Heinz Kaiser AGInventors: Heinz Kaiser, Ernst Hänggi, Rudolf Stadelmann

Patent number: 4650867Abstract: A process for the preparation of 2,4,6-tris(aminophenylamino)triazines by condensing s-trichlorotriazine with 3 equivalents of a partially protected phenylenediamine and subsequently removing the protective groups, which process comprises carrying out the condensation in an anhydrous or water-containing aliphatic C.sub.2 -C.sub.4 alcohol, in the presence of an acid acceptor.2,4,6-Tris(aminophenylamino)triazines are important intermediates in dyestuff chemistry and are used, inter alia, for synthesizing textile, leather and paper dyes as well as pigments.Type: GrantFiled: March 19, 1986Date of Patent: March 17, 1987Assignee: Ciba-Geigy CorporationInventors: Roland Ronco, Willy Stingelin, Ernst Hanggi
