| 65 | Method and device for determining a machining axis | US14655071 | 2014-01-27 | US09714881B2 | 2017-07-25 | Martin Rogalla |
| In order to determine the machining axis of a rotatable workpiece blank, a reference workpiece, which has bearing surfaces concentric to its imbalance reference axis, and subsequently a workpiece blank are received in a measurement device, and as yet unmachined surface regions of the reference workpiece and of the workpiece blank are measured by a sensor device, and the measured position data are stored by a computer as a reference partial surface and a blank partial surface in a data storage device. The computer calculates deviations between the blank partial surface and the reference partial surface and, from these, an imbalance effect which is expressed by the position of the main axis of inertia of a given workpiece. The machining axis is calculated by adding an offset to the position of the main axis of inertia, which offset has been empirically determined with the aid of the actual imbalances of previously produced workpieces measured relative to the machining axis. | ||||||

| A flywheel energy storage system incorporates various embodiments in design and processing to achieve a very high ratio of energy stored per unit cost. The system uses a high-strength steel rotor rotating in a vacuum envelope. The rotor has a geometry that ensures high yield strength throughout its cross-section using various low-cost quenched and tempered alloy steels.

| Tennis players need multiple playing racquets available for their use, and the mass proportions of each one, needs to match all the others exactly, otherwise players will likely experience degradation in their swing mechanics when unmatched racquet's were used.BOC provides a simplified solution, through comparator testing, which provides a means for mass proportions matching, of 2 tennis racquets or similar swing-able massive implements.Whereby, a Reference massive object/racquet having a perfected swing mass is directly compared to a 2nd massive object/racquet having an imperfect swing mass, that can then be adjusted to match the reference objects perfected swing mass, by placing small metal strips of mass by trial [per our plan] onto the frame/moment of 2nd object. Then finally both tested racquets will become exactly the same perfected swing mass proportions. | ||||||
