Abstract: A clamped access floor panel assembly for mounting an access floor a spaced distance above a base floor. A plurality of panels are supported by an array of pedestals to form a floor surface. The panels are clamped to the pedestals at their corners and optionally at their side edges by clamping devices accessible through small access holes.

Abstract: Apparatus for cutting lumber to random or specified clear lengths by removal of sections containing defects and by making single end or intermediate cuts, includes infeed means for transporting a piece of lumber, locating means for locating the piece of lumber longitudinally in the apparatus, a fixed saw for cutting the piece of lumber at a first position, and a sliding saw selectively positionable longitudinally with respect to the fixed saw for cutting the piece of lumber at a second position which is located a spaced distance from the first position co-extensive with the extent of the defect. The fixed saw also is configured for operation independently of the sliding saw for making the single cuts.Saw positioning means positions the sliding saw longitudinally, based on commands from a computer for removal of the defect with the minimum removal of clear lumber.
