Abstract: At the remote end of a Type C track circuit, the conventional diode and the winding of a power transfer relay connected in multiple are connected across the rails over a transfer relay front contact. This transfer relay and the track relay at the near end are normally energized by the same half cycle of track current from the alternating current (AC) source. If the AC source fails, a track battery is connected across the rails at the remote end in series with the diode and transfer relay multiple network over a transfer relay back contact. The diode is so poled that the track relay is energized from the track battery with the same polarity as the rectified alternating current and does not release during the transfer operation. The diode bypasses substantially all track battery current away from the transfer relay.

Abstract: A seal for rotatable shafts utilizes a ferrofluid as a sealant and lubricant. As a sealant, the ferrofluid acts to exclude particulate matter from passing through the seal area contaminating internal mechanism elements, while as a lubricant, the ferrofluid forms a film between the shaft and the elastomer-material seal element; thus, cooling and lubricating the contact interface and acting to extend the life of the related components. The seal assembly has permanent magnetic elements which create a magnetic-field gradient, causing magnetic-field maxima at points immediately surrounding the contact point between the seal-elastomer material and the shaft. The ferrofluid is entrained magnetically within the interface region; thus, insuring continual lubrication of the contacting surfaces, while further, the entraining forces prevent leakage of the ferrofluid from the region.
