Abstract: The present invention is directed to a bone plate assembly including a bone plate, bone screws received in apertures in the assembly, and a screw retaining member fixed to the bone plate which covers at least a portion of the bone screws. When bone screws have been received by the bone plate and inserted into bone and/or tissue, the bone plate assembly can be used to fuse anatomical structures together, such as adjoining bones, or to heal a fracture in bone.

Abstract: The conversion unit is a simple frame structure applied inwardly of a window opening, such as in a residential basement equipped with metal casement windows. It comprises a pair of like triangular end members or panels bridged across inner upright edges thereof by a light-transmitting portion in which a pair of ornamentally decorated sliding panels are mounted, as in a pair of overlapped grooves in a frame part of the panel portion. The unit is applied with outer vertical edges thereof in abutted engagement with a wall carrying the casement window and with upper margins of the generally triangular open frame structure in upwardly flush engaging abutment with the room ceiling just above the casement window zone. the sliding panels are chosen of a decorative plastic, semi-rigid sheet, preferably somewhat flexible in nature, and also by preference provision is made for a removal of the unit from the casement area for full access to the castment window from its interior.
