| A multiple channel rotary electrical connector can include multiple first contacts which are radially spaced apart from each other, and multiple second contacts which electrically contact respective ones of the first contacts while there is relative rotation between the first and second contacts. The second contacts may be radially spaced apart from each other. A well tool can include one section which rotates relative to another section of the well tool, and a multiple channel rotary electrical connector which includes multiple annular-shaped contacts that rotate relative to each other. A method of operating a well tool in a subterranean well can include producing relative rotation between sections of the well tool, and communicating multiple channels of electrical signals between the sections while there is relative rotation between the sections. The communicating can include electrically contacting multiple annular-shaped contacts with each other. | ||||||

| 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. | ||||||

| 193 | Arrangement in the transfer of electric current to a propulsion device provided with an electric motor in a ship or equivalent | EP95850224.7 | 1995-12-08 | EP0716013A1 | 1996-06-12 | Niemi, Aarno |
The invention concerns an arrangement in the transfer of electric current to a propulsion device provided with an electric motor in a ship or equivalent, which propulsion device is mounted on the ship's hull (1) as rotatable in relation to a substantially vertical axis of rotation. At the lower end of the vertical frame (15) of the propulsion device, a lower housing (11) is mounted, in which an electric motor (12) is fitted which drives a propeller (14) which revolves around a substantially horizontal shaft of rotation. The current transfer arrangement comprises a stationary conductor part (2) mounted stationarily in relation to the hull (1) of the ship and a mobile conductor part (3), which is installed on the vertical frame (15) of the propulsion device. The stationary conductor part (2) and the moving conductor part (3) consist of an annular part and of a part of circular section fitted inside the annular part coaxially with said annular part, so that an annular intermediate space (17) remains between the stationary conductor part (2) and the mobile conductor part (3). In the intermediate space, an electrically conductive liquid, amorphous or equivalent medium (4) is fitted in constant contact with the stationary conductor part (2) and the mobile conductor part (3), the electric current being transferred through the electrically conductive medium (4) from the stationary conductor part (2) to the mobile conductor part (3) and from it further to the electric motor (12). |

| 194 | Differentially-pumped ferrofluidic seal | EP93304871.2 | 1993-06-22 | EP0576258A3 | 1994-08-03 | 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. |

| 195 | Improved liquid metal circulation in an acyclic generator collector | EP87115852 | 1987-10-28 | EP0274015A3 | 1988-07-20 | Hatch, Burton Dilworth |
To minimize the effects of magnetohydrodynamic surge forces acting on the liquid metal (32) in the collector gap (31) of an acyclic generator (10), fluid flow impedance members in the form of annular, axially spaced compliant brushes (44) are disposed in the outboard liquid metal containment gap (40b) defined between closely spaced, stator and rotor stepped surface formations (36, 38). These brushes (44) impede the communication to the liquid metal (32) in this containment gap (40b) of pressure fluctuations generated in the liquid metal (32) in the collector gap (31) resulting from variations in the generator current transiting the collector gap (31). A hydrostatic pressure head may thus be maintained consistently at a location intermediate the collector and containment gaps (31, 40b) for pumping the liquid metal (32) in a recirculating path. |

| A connector module (11) for an electric motor is in the form of first and second contact ball-bearing assemblies (12, 13) mounted coaxially about the motor shaft (5) in a single plane, such that a first component (15) rotates with respect to a second component (16), and the assemblies serve to provide a constant electrical connection between a source of power and the rotor of the motor. In an alternative arrangement, the electrical connection is effected by means of mercury reservoirs. The described invention extends to arrangements for sensing the displacement of the rotor and stator of electric motors, involving the use of a displacement encoder bearing a sensible pattern which is located on the stator and sensing circuitry on the rotor. The encoders may take the form of parallel tracks, each bearing a sequence of portions exhibiting different sensible characteristics or, alternatively, may take the form of an element bearing a pattern in the form of a sequence of three portions each bearing different sensible characteristics. | ||||||

| An improved roller electrode for use in electric-resistance welders has relatively rotatable components (38, 40) separated by very small gaps (51, 52), and a liquid contained in the gaps. Said liquid is nontoxic, and is highly conductive, both electrically and thermally, and is of a composite eutectic mixture of appproximately 61% Ga, 25% In, 13% Sn, and 1% Zn, by weight. A protective coating having a thickness between 0.0025 and 0.025 mm is plated on said surfaces of at least one of the components (38, 40), and is gold and/or a material from the platinum family, such as rhodium (Rh). Coolant is circulated through one of the components (38, 40), and the conductive liquid cools the other component. The rotor component (40) may be formed of a sintered mixture of copper (Cu) and tungsten (W). | ||||||
