| Number | Title | Issue Date |
| 6876291 | Electrical resistor for measuring preferably high-frequency alternating currents The present invention relates to an electrical resistor (1), in particular for measuring alternating currents of high frequency, comprising connectors (2, 3) for feeding the current to be measured and connectors (4, 5) for tapping the voltage to... | 04/05/2005 |
| 6734404 | Heating elements with reduced stray magnetic field emissions A wire-based heating element is provided having first and second portions twisted about each other such that magnetic flux emitted from one portion is substantially cancelled by magnetic flux emitted from the other portion. A bonding material that fixedly connects t... | 05/11/2004 |
| 5426351 | Heater coil for electron tube A heater coil for an electron tube includes a spiral wire which is double wound to be cylindrical, and a connection wire which is formed on an upper face of the spiral wire in a horizontal plane. The connection wire is shaped to have at least two bent por... | 06/20/1995 |
| 5235311 | Magnetic variable resistor A magnetic variable resistor has an elongated band of electrically resistive magnetic material, with the side edges tapered to a sharp point so that the skin effect causes current to migrate to the edges to create greater resistance. A layer of insulating... | 08/10/1993 |
| 5229743 | High voltage protection resistor A protection arrangement for a high voltage tube includes a low inductance disk resistor connected in series with the anode of the tube. When an electrical discharge occurs within the tube, the increased anode current flows through the resistor which abso... | 07/20/1993 |
| 4916428 | High voltage, outdoor, air cooled, dynamic braking resistors and power distribution system incorporating the same An electrical resistor having first and second cylindrical resistance windings helically wound closely adjacent one another about a common axis and wound in opposite directions about such axis. The helical windings of the resistor are connected in paralle... | 04/10/1990 |
| 4866411 | Film-type cylindrical resistor, and method of making it A film-type cylindrical resistor in which the end caps fit over the environmentally protective coating. Both the resistive film and the environmentally protective coating are applied by screen printing. Termination films are provided at the ends of the re... | 09/12/1989 |
| 4568907 | Low inductance resistor for high current limitation A low inductance resistor for high current limitation is arranged from a single conductor wrapped in a continuous direction to form a plurality of turns wherein current transport through each of the turns induces a corresponding magnetic field to oppose t... | 02/04/1986 |
| 4319216 | Discharge resistor A discharge resistor adapted to be mounted on a rotatable shaft of a dynamo-electric device comprises a pair of spirally wound, insulated resistor elements and means for supporting these elements approximately coaxially with the shaft. Each of the resisto... | 03/09/1982 |
