| 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. Low-cost is also achieved by forging the rotor in a single piece with integral shafts. A high energy density is achieved with adequate safety margins through a pre-conditioning treatment. The bearing and suspension system utilizes an electromagnet that off-loads the rotor allowing for the use of low-cost, conventional rolling contact bearings over an operating lifetime of several years. | ||||||

The apparatus comprises a ball support assembly and a weight scale. The ball support assembly has a cradle which holds the bowling ball and the assembly has weight supports. Whenever the scale is read, one of these weight supports is supported by the scale and another is supported apart from the scale. In a first orientation of the bowling ball with a first hemisphere of the ball closer to the weight support supported by the scale, a first scale reading is determined. Then in a second orientation with the first hemisphere of the ball farther from the weight support supported by the scale, a second scale reading is determined. Comparison of the two scale readings allows determination of the weight imbalance of the ball's two hemispheres. This weighing apparatus is able to use a single, readily available commercial scale, making it low in cost to produce, and the use of an electronic weight scale allows fast, accurate readings. | ||||||

| 149 | METHOD AND DEVICE FOR DETERMINING A MACHINING AXIS | US14655071 | 2014-01-27 | US20150346048A1 | 2015-12-03 | 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. | ||||||
