A preheater for heating either intermediate or small size electrical wire includes left and right inductors, each having a longitudinal passageway through which the wire to be heated is passed, one inductor being fixedly mounted on a mounting plate with its passageway vertical and the other inductor being pivotally mounted on the mounting plate so that its passageway can be either positioned vertically or tilted at an angle from vertical, a lower wheel rotatably mounted on the mounting plate below the inductors, a first upper wheel sized for use with intermediate diameter wires and a second upper wheel sized for use with small diameter wires, only one of the upper wheels being mounted on the mounting plate at a time. When intermediate size wire is being run, the pivotally mounted inductor is positioned with its passageway vertical and the first upper wheel is rotatably mounted on the mounting plate above the inductors and vertically aligned with the wheel. When small size wire is being run, the pivotally mounted inductor is tilted and the second upper wheel is rotatably mounted on the mounting plate above the inductors and aligned with the tilted inductor. In use, the wire being heated passes around the upper wheel, through one inductor, around the lower wheel, through the other inductor and then around the upper wheel again.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
