A display assembly for posters or signs includes a cover frame having a clear sealed window at the front surface thereof. The display assembly is generally rectangular, the cover frame having four outwardly facing walls configured to slide into forwardly extending closely fitting walls extending from a one piece wall-mountable shroud-forming frame. Magnetic strips affixed to interior faces of the shroud-forming frame capture and hold an inserted cover frame, and the closely fitting shroud walls and immediately confronting cover frame walls serve to defeat the insertion of conventional tools to remove the cover when so emplaced. A special spatulate tool is configured with projections stressed to spring out of the plane of the blade in the relaxed state. The extensions are temporarily pressed flat during insertion, to spring outward when inserted to maximum depth into the assembly, the extensions when thus deployed confronting and engaging a rear portion of the cover frame. Withdrawal of the tool causes withdrawal of the cover frame for replacement of the contents.

The present invention provides a fast, efficient, precise method and apparatus for compounding solutions for use in hyperalimentation therapy. The apparatus includes a controller for entering the volume and specific gravity of the solution to be compounded. A load cell monitors the weight of the solutions that have been transferred to a collection vessel and in connection with the controller thereby maintains the precise amount of each therein. The controller also surveys various process conditions and warns of any failure of those conditions. Peristaltic pumps are used for the delivery of the compounding solution to maintain the solutions in a sterile condition.
