Abstract: An adjustable trunnion valve includes an obturator, a valve stem, at least one valve seal, and a trunnion. The trunnion and obturator are configured to translate the obturator along a longitudinal axis extending through the trunnion and the obturator upon rotation of the valve stem beyond one or both of its open position and its closed position. A method of operating an adjustable trunnion valve having an obturator coupled to a trunnion and a valve stem includes passing a fluid through the adjustable trunnion valve and rotating the valve stem to rotate the obturator about an axis of rotation and to simultaneously translate the obturator in a direction along the axis of rotation while the obturator is supported by the trunnion and while the fluid flows through the adjustable trunnion valve.

Abstract: An upright housing has a transparent side. A plurality of compartments are positioned in rows and columns in upright arrangement in the housing next-adjacent the transparent side. Each column represents a day of the week and each row represents a week of a month. Each compartment is adapted to store a day's medication. A calendar marking indication on the transparent side of the housing labels each compartment as a different day of the month. An opening is formed through the bottom of the transparent side of the housing. A chute device in the housing extends in common from each of the compartments to the opening. A key-operated control device maintains medication in each compartment and releases medication from a selection compartment to the opening upon operation.
