Abstract: A metal plate (11) for protecting plumbing pipes and plastic electrical conduits (13) from being pierced by a nail or screw when the wall covering is attached. Said plate is a generally flat rectangular metal plate (11) having metal tabs (12) for aligning said plate on concrete foundation form boards (10) and metal prongs (13) which act as nails to hold said plate in position until concrete (15) is poured. The concrete (15) flows around the concrete gripping prongs (14) where said concrete (15) bonds thereby locking said plate (11) permanently in place.

Abstract: A device 10 for crushing medicaments originally formed in pill of tablet contour into a fine powder. An impact device 140 moves from a first energy stored position latched thereagainst spring pressure awaiting tripping of the latch or cam 190 by the pill which has been ensconced in a container embodied as an envelope 260. The envelope 260 is placed in a slot 84 and oriented to trigger a switch 234 which releases from a captive position the hammer 142. The hammer 142 advances linearly impacting against an anvil 89 upon which the envelope 260 and the enclosed pill awaits. The explosive force of the hammer 142 creates a powder substance because of the explosive nature of the hammer's 142 contact against the anvil 89. While the hammer 142 is being withdrawn under motor drive 212, the envelope 260 may be removed for access to the interior contents for subsequent dispensation.
