An exercise machine for performing barbell type free weight lifting exercises has a power cage or Smith press type frame, an elongated bar held on the frame in a substantially horizontal resting position, and an adjustable exercise mass assembly that allows a user to select an exercise weight from among a plurality of choices of different exercise weights provided by the exercise mass assembly. The system is formed by a frame defining an interior space for receipt of a deposit of a therapeutically effective dose of a biologically active compound. The bed further including a mechanism that control movement of the foot section relative to the seat section. The wall conduit system includes front and back housings, a sliding plate, and a third nozzle. The gripper is closable to grip and openable to release the leading end of the flexible strip so as it moves into its downstream positions it pulls the strip downstream above the surface and, once the cutter has operated, the gripper opens to drop the sheet severed from the strip down onto the surface. This method for patterning an EUVL reticle has the advantages of avoiding the process steps associated with depositing and patterning an absorber layer and providing control of the phase and amplitude of the reflected field with high spatial resolution.
