Abstract: The present invention provides a power frequency, i.e., time-varying, magnetic field (PF-NF) detector system for characterizing the operational condition of a remote facility responsive to time-varying magnetic fields generated by electrical transmission lines associated with the remote facility. The PF-MF detector system advantageously includes a PF-MF sensor which generates N time-varying magnetic field data sets, and a PF-MF analyzer which generates an operational condition assessment responsive to the N time-varying magnetic field data sets, wherein N is an integer greater than or equal to 1. Additionally, the PF-MF detector system includes an accumulator which stores and forwards the N time-varying magnetic field data sets to the PF-MF analyzer via a communications channel. A method for characterizing the operational condition of inaccessible electrical equipment responsive to the time-varying magnetic field generated by a transmission line are also described.

Abstract: An adjustable motorcycle passenger floorboard is attached at either side of a motorcycle frame below the rear seat. The device has a cylindrical rail having a brace at either end. The braces have slotted bolt holes for allowing the device to be bolted to the frame. A split clamp is attached around the cylindrical rail. The clamp, when loosened, can be slid between the braces of the cylindrical rail for allowing a continuous adjustment of the floorboard. The floorboard is attached to the clamp by a bar which can be rotated about its axis in a notched recess in the clamp for adjusting the attitude of the floorboard relative to the motorcycle. There are two adjustments in the device; one for adjusting the floorboard in a fore and aft position relative to the frame, and the other for adjusting the attitude or rake of the floorboard relative to the frame.

Abstract: Ferric chloride from the selective chlorination of titaniferous material such as ilmenite is partially oxidized to obtain a chlorine-rich stream and byproduct iron oxide. Unreacted ferric chloride is separated as solid particles from said stream and at least a portion of said particles are returned to the chlorination operation for absorbing heat generated in such operation.
