This invention is directed to compounds of the formula :and their pharmaceutically acceptable salts, wherein R1, R2, and R3 are as defined herein; intermediates for the synthesis of such compounds, pharmaceutical compositions containing such compounds; and methods of using such compounds in the treatment of neurological and psychological disorders. At an input rerouting circuit, the selected elements are rerouted from the second data stream into the first data stream; a token inserted in the second data stream identifies a position of the rerouted element. The measured opening torque is then compared with a desired range of opening torque and an adjustment of the closing torque for the particular closing device is calculated and performed such that, upon the closing device screwing screw caps or closures on containers in a run of containers, the closed containers are openable using an opening torque within the desired range of opening torque. The apparatuses, methods, and systems also comprise a control handle coupled to the cable system for the user to grasp, wherein the cable system actuates to either one of increase and release a tension to the grasped control handle, and wherein the control handle comprises at least one control to regulate the either one of increase and release the tension. An accompanying cannula together with the dilator form a system for the distraction of the adjacent spinous processes, stabilization of the spinous processes with respect to the system and creation of a working channel for the implantation of an interspinous spacer. The mounting area is provided by a flange portion of the rear motor wall and positioned radially outwardly relative to the output shaft, and provides mounting of the control switch with a user interface that is exposed from the fan frame.
