| 122 | Fluid contact for a DC machine | US493900 | 1974-08-01 | US3984715A | 1976-10-05 | Dieter Kullmann; Peter Henninger |
| This invention concerns an improvement in a fluid contact arrangement employed in a DC machine. The invention provides a contact fluid which is interposed between the rotor and the stator of the machine. The fluid is ferromagnetic. Further, the invention provides a magnetic field which is directed perpendicular to the air gap. The effect of the magnetic field on the ferromagnetic contact fluid is such that the fluid is retained within the gap both when the rotor is at a standstill and when it operates at its normal speed. | ||||||
| 123 | Isobaric device with rotating electrical contacts | US613195 | 1975-09-15 | US3972577A | 1976-08-03 | Joel Marie Charles; Jean-Pierre Maurice Ghiglione |
| An isobaric device housing rotating electrical contacts, including a wateight housing filled with an electrically insulating liquid at a pressure which is substantially the same as the pressure of the environment in which the device is to be used, and one or more rotating electrical contacts formed by concentric conductive collars located between pairs of insulating rings, which rings are separated and sealed by sealing joints of elastomeric material, the space defined between said rings, collars and sealing joints being filled with an electrically conductive liquid, and washers on each outer end of the contact structure limiting axial movement of the sealing joints which joints also transmit pressure. A plurality of such contact structures may be stacked together on a common shaft thereby forming a multi-contact device. A process for manufacturing such contacts is also disclosed. | ||||||
| 124 | Mercury loaded brass ball bearing | US3701072D | 1971-02-22 | US3701072A | 1972-10-24 | BJORN JAMES M; MARX FREDERICK JR |
| The ball bearing has inner and outer ball races of brass and a series of balls made of brass running in annular grooves in the mating faces of the races. The entire space within the recesses around the balls contain mercury. Bearing seals are disposed between the races adjacent their outer sides. The spaces between the seals and the sides of the mercury are filled with oil. The races are adapted to be connected in an electric circuit to permit the transmission of low voltage signals without frictional audio interference during rotation of the races.

The inner and outer discs are secured and sealed to the inner and outer members, respectively, and have radially overlapping circumferential portions which bear yieldably against one another to form a fluid seal between the members. A viscous slipring construction embodying the rotary seal assembly.

| 126 | Power spindle for electrochemical grinding | US3616428D | 1969-09-05 | US3616428A | 1971-10-26 | BOGUE DAVID L |
| A power spindle for electrochemical grinding machine utilizing a grinding wheel, there being an electrical connection to the moving wheel accomplished through a body of mercury. An annular recess formed in a drive housing on the rotating spindle confines the body of mercury and an annular plate, insulated from the spindle and forming a drive motor, is mounted in a manner to be supported by the motor and fastened to project into the annular recess to create an electrical connection between a secondary housing surrounding the motor and the drive housing which rotates with the spindle.
