A locking system for mechanical joining of floorboards. For horizontal mechanical joining there is a projecting portion with a locking element which cooperates with a locking groove in an adjacent board. A tongue-and-groove joint for vertical mechanical joining has cooperating upper abutment surfaces and cooperating lower abutment surfaces which are essentially parallel with the principal plane of the floorboards and of which the lower abutment surfaces are positioned essentially outside the outer vertical plane, i.e. displaced relative to the upper abutment surfaces. The tongue is movable at an angle into the groove and the locking element is insertable into the locking groove by mutual angular movement of the boards about the joint edges.

A surgical instrument includes a detachable tool assembly. The assembly includes a connection rod and a tool, such as a pair of jaws or an electrode. The instrument also includes a shaft operatively connected to a handle movable between operating positions and an ejected position. A tubular housing encloses the shaft and a collet. The collet is attached to the rod and movable between the positions. The fingers of the collet are flared apart in the ejected position but collapse to capture the connection rod in the operating positions. A tongue-and-groove arrangement provides a secondary coupling between the assembly and the housing when the handle is in the operating positions.

A method of producing a hardwood flooring product, including the steps of processing a strip of raw wood into a blank having a predetermined thickness and width, and top and bottom surfaces defining parallel planes relative to each other, and splitting the blank along the width of the blank from one side to the other to form two low profile flooring strips having the same width as the blank and a thickness less than one-half the thickness of the blank. The splitting step includes the steps of providing first and second circular saw blades mounted on spaced-apart vertical axes for rotation in a single plane intermediate and parallel to the planes of the top and bottom surfaces of the blank and positioning the blank on conveying means upstream from the saw blades with the plane of rotation of the saw blades intermediate and parallel to the planes of the top and bottom surfaces of the blank for movement of the blank from an upstream position to a downstream position relative to the saw blades. The blank is moved downstream into the plane of rotation of the saw blades during rotation of the saw blades thereby horizontally splitting the blank to form first and second low-profile flooring strips. Interlocking members, such as molded, mating tongue and groove members, are molded into first and second longitudinally-extending side edges of the flooring strips for securing together the flooring strips when placed side-to-side to form a floor.
