Abstract: There is provided a novel process for the preparation of a hydrocodone salt. In particular, there is provided a novel process for the preparation of a free-flowing slurry of a hydrocodone salt, for example, a free-flowing slurry of hydrocodone bitartrate hemipentahydrate.

Abstract: The climbing tree stand is a tree stand including a drive wheel assembly fixed onto a support frame such that the climbing tree stand may be self propelled along the trunk of a tree. A top guide secures the upper end of the support frame about the trunk of a tree in position for climbing, and a bottom guide maintains the support frame's lower end in alignment with the tree trunk for climbing. A platform for sitting or standing is attached to the lower end of the support frame. A climbing wheel assembly includes at least one climbing wheel adapted for engagement with the a tree, and a drive mechanism including a ratchet lever arm operatively coupled the at least one climbing wheel such that operation of the lever arm to rotate the at least one climbing wheel propels the climbing tree stand along the tree trunk tree.

Abstract: A reservoir is provided having an upper reservoir body connected to a lower reservoir body. The reservoir includes and inlet port and an outlet port that are separated by a filter, which filters fluid flowing from the inlet to the outlet. In addition, a re-circulating cover is provided to separate fluid returning through the inlet port from the fluid in the main reservoir chamber. A re-circulating cover is provided that defines a re-circulating chamber. Fluid communication between the main reservoir chamber and the re-circulating chamber is restricted by the re-circulating cover until the main reservoir fluid reaches a predetermined temperature threshold. Accordingly, a given quantity of fluid is re-circulated from the inlet port to the outlet port and is continuously warmed before mixing with main reservoir fluid. Such a reservoir design helps to eliminate cold start up noises.
