Abstract: The present disclosure describes a draping system for a two-tiered hospital instrument back table can be used to quickly and conveniently create a sterile field. The system has a drape that is a single piece of material, desirably a film that may be clear. The single piece of material has other material attached to it on its upper side or surface in areas that generally coincide with the two upper surfaces of the table when the drape is installed on the table, and that has a lower coefficient of friction than the single piece of material. The drape may be held in place with a continuous or discontinuous band that encircles the upper tier or the upper tier support posts.

Abstract: The present invention provides a generally circular cutting blade suitable for use in conventional circular saws or equivalent power tools such as table saws and the like. The cutting blade of the present invention utilizes a pair of angled or concave portions or segments (as viewed from one side of the blade). A first portion is located at the radially outward periphery of the blade and a second portion is disposed radially inwardly therefrom. These first and second angled or concave portions are connected by a relatively flat blade portion that permits the radially outward portion to flex or deflect slightly from side to side as the blade is rotated through a work piece.
