Patent number: 9746406Abstract: A flow test machine 2 which, for example, is able to be used for viscosity tests on plastics, comprises a test piston 4, a test channel 38, at least one test weight 72 and a drive unit 92. The test piston 4 is able to move through the test channel 38 by means of a weight force 79 of the test weight 72. The test weight 72 is able to be loaded by an actuating additional force 108, 108? by means of the drive unit 92 between a starting position 151 and an end position. The actuating additional force 108 enables a movement of the test piston 4 in the direction of the weight force 79, said movement being accelerated in comparison with an effect of the weight force 79. In a melt viscosity test, after a heating step, a thermoplastic plastic is pressed through a test channel 38 by a test piston 4. In a measurement preparation step and/or a cleaning step, the test mass is lowered along a weight force direction 79 under the influence of an actuating additional force 108, 108?.Type: GrantFiled: September 28, 2015Date of Patent: August 29, 2017Assignee: ZWICK GMBH & CO. KGInventors: Marcus Flock, Franz Ganser, Ulrich Kindermann, David Völzke

Patent number: 6993435Abstract: For the automatic determination of the diameter of a tool, particularly a saw blade for an automatic wall saw, which is driven by a motor via a gear unit, the moment of inertia of the tool is used as an indicator for its diameter. Three basic solution variants are introduced. In particular, the system including a motor, gear unit and tool is treated as a dual-mass oscillator such that the elasticity of the shafts and gears is arranged as a torsion spring between the inertial masses in two discrete points while taking into account two coefficients of friction including coefficients of the known inertia of the motor rotor (?R) and of the tool (?S). This system can be described by equations which are then simplified by reasonable assumptions or premises. The selected formulations are solved for the moment of inertia of the tool to determine the diameter therefrom and to make an optimal adjustment for the drive possible which is adapted to the respective tool.Type: GrantFiled: April 12, 2004Date of Patent: January 31, 2006Assignee: Hilti AktiengesellschaftInventors: Josef Schittl, Eduard Sever, Georg Studer, Marcus Flock, Guenther Veik, Roland Schaer, Christoph Würsch

Patent number: 6869258Abstract: A drill stand (1) for a manually operable tool device (2) is formed of a fixedly mountable base plate (4) having a through passageway (5) extending perpendicularly therethrough for the passage of a clamping bolt (6) having at least one axially effective stop shoulder (7a, 7b), so that at least one detent means (8) with an axially effective counter shoulder (10a, 10b) for axial form-locking engagement of the shoulder stops (7a, 7b) of the clamping bolt (6). At least one manually operable eccentric cam (11a, 11b) affords axial clamping of the clamping bolt (6) locked by the detent means (8) and arranged relative to the through passageway (5).Type: GrantFiled: October 1, 2002Date of Patent: March 22, 2005Assignee: Hilti AktiengesellschaftInventors: Marcus Flock, Stefan Hammerstingl
