| An eddy current drive (711) has an electromagnet (15, 17) and an armature (19). Either one of the electromagnet or the armature is coupled to a motor shaft (31) so as to rotate therewith, while the other is coupled to a load portion (21). The motor can rotate at a continuous speed, while the speed of the load portion can vary by varying the energization of the electromagnet, so as to vary the coupling between the electromagnet and the armature. The electromagnet is energized by way of bearings (613, 615). The bearings provide a rotary coupling. In another embodiment, an electrical generator (713) is provided. The rotation of the motor shaft (31) generates electrical current that is used to energize the electromagnet. The amount of the electrical current that is provided to the electromagnet can be varied to vary the output speed of the load portion. | ||||||

Eine Vorrichtung zum galvanischen Behandeln eines drehend antreibbaren Körpers (1) in einer Elektolytwanne, insbesondere zum Aufkupfern und/oder Verchromen von Tiefdruckzylindern, ist mit einer Stromübertragungsvorrichtung (6) ausgestattet. Diese weist einen mit dem Körper (1) mitdrehenden Teil (eine Stromübertragungshülse (16)) sowie einen stationären Teil (einen Lagerkörper (17)) auf. Die Stromübertragung von einem zum anderen Teil erfolgt über ein in einem geschlossenen Raum (20, 41, 38, 40) vorhandenes und sich bei Raumtemperatur im flüssigen Zustand befindendes Metall oder eine Metallegierung. Die Stromübertragungsvorrichtung (6) ermöglicht eine absolut staubfreie Übertragung von hohen Strömen; ausserdem kann auch das zum Drehen des mitdrehenden Teiles erforderliche Drehmoment erheblich reduziert werden, da die durch einen relativ hohen Anpressdruck der bisher zur Stromübertragung erforderlichen Kohlenbürsten bedingte Reibung wegfällt. |

| 68 | Differentially-pumped ferrofluidic seal | EP93304871.2 | 1993-06-22 | EP0576258A2 | 1993-12-29 | Toboni, James C.; Black, Thomas J.,Jnr. |
A ferrofluidic seal arrangement for sealing a high-speed rotary shaft (15) which passes between an environment at atmospheric or high pressure and an environment (14) at high-vacuum is provided, which is especially useful in a high-speed rotating anode apparatus for generating x-rays in a CAT Scan apparatus or the like. A differentially-pumped region (50) between a multi-stage ferrofluidic seal (19,22,48,49) and a single-stage seal (43 to 47) insures that no seal bursting into the-high-vacuum region occurs. Bearings (17, 18) supporting the shaft are arranged in a mechanically-stable arrangement but are isolated from the high-vacuum environment. Thus, neither the high-vacuum environment (14) nor the differentially-pumped region need be continually mechanically pumped, and a relatively light-weight apparatus results. The apparatus is electrically grounded by transferring the charge on the anode (58) through the high-speed shaft out of the vacuum environment and to a slower-rotating shaft (40) via an electrically conductive, flexible drive belt (37), the slower shaft rotating at a speed at which grounding by conventional means (41) is feasible. |
