Abstract: Accordingly, a tank, preferably on a wheeled vehicle such as a railcar or trailer, is provided with a protective liner. Two electrodes are preferably permanently mounted within the tank and respectively connected to a monitor. Another two ground connections are made from the monitor to the tank. At least one of the two probes in the tank are utilized with the monitor to measure the voltage between the tank and the selected probe. When the tank is filled with an ionic solution, a breach of integrity of the liner results in a voltage corresponding to the difference in potentials of the metals forming the probe and tank is read by the monitor. This triggers an alarm. Furthermore, the monitor provides a voltage or current from probe to probe, probe to shell, and shell to shell on a periodic basis to measure and then record the performance of the liner.

Abstract: A tufting machine has a yarn feed roller assembly with a plurality of rotatable driver rollers driven at different speeds and a plurality of actuators in the form of a pivotable arm having in one embodiment a pair of yarn feed reels one of which is arranged to selectively press yarn into engagement with one of the drive rollers and the other arranged to selectively press yarn into engagement with another drive roller. Yarn is engaged by each actuator and a selected drive roller for a period of time determined by a pattern. The longer the actuator engages the high speed roller during the stroke of a tufting machine needle the greater will be the pile height of the tufts produced and alternatively the longer the actuator engages the lower speed roller during the needle stroke the lower will be the pile height. Pile height variations between a high pile and a low pile may be obtained by controlling the proportion of time during the stroke that the yarn engages with the high and low speed rollers.
