Abstract: A sliding sleeve is provided that includes a housing, a spinner sleeve, an inner sleeve, a collet, an actuator, and an indexer. An object passing through the interior of the sliding sleeve is caught by the actuator forcing the indexer to move linearly downward. The linear downward movement causes the indexer to rotate one halfstep at which point the object is released. The indexer, biased towards the upward position, is returned to the upper position while at the same time is again rotated half a step. Once the pre-set number of steps is reached the indexer moves upward to support the collet. With the collet supported the next object passing through the interior of the sliding sleeve is retained by the collet which in turn forces the inner sleeve to move downward. With the inner sleeve moved to the down position a flow path is opened through the sleeve from the interior to the exterior of the sliding sleeve.

Abstract: A dual fluid heat exchange system is presented that provides a stable output temperature for a heated fluid while minimizing the output temperature of a cooled fluid. The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. Alternatively, the low flow rate section of the tank may be warmer than the re-circulated section, and thus allow the re-circulated section to be cooler than the output temperature of the warmed fluid.
