Abstract: In a method for bonding plastic objects together by means of a hot-melt type of adhesive, in addition to or during the heating and addition of a plasticizer-resistant hot-melt adhesive, at least one of the objects to be bonded, is heated up in the area to be bonded beyond the melting temperature of the material of which it is made. The method is particularly advantageous for the joining together of multi-layered plastic pipes. The result is the generation of a method for bonding objects by means of a hot-melt type of adhesive that can also be applied with materials for which it was hitherto impossible to apply hot-melt adhesion.

Abstract: A power-operated hand tool has a handle portion or frame that is gripped by the operator using two hands. A clamping portion comprising a pair of opposed jaws extends outwardly from the handle portion and utilizes an air cylinder to move an upper clamping jaw toward and away from the lower fixed jaw. Both jaws have free outermost ends that cooperatively define an entry mouth into a clamping zone between the jaws. In use, a group of individual boards are laid side-by-side in edge-to-edge relationship slightly above a work surface so as to permit the lower jaw of the tool to be slipped beneath the boards while the upper jaw becomes placed above the boards, both of which extend transversely across the boards. Upon actuation of the air cylinder, the upper jaw comes down into flattening engagement with the boards, causing them to be clamped down into generally flat alignment with one another in a common plane so as to present a substantially smooth top surface.

Abstract: The present invention is directed to a process whereby low-grade lumber, (i.e., lumber having surface defects such as knots, voids, wane, and bark pockets, and warp defects such as twist, bow, crook and sweep), is converted to higher grade lumber and panel products. The process of the present invention involves first categorizing low-grade lumber, arranging a specified number of the categorized low-grade lumber side by side in a manner which offsets the surface defects on adjacent lumber by a minimum distance, and then face-laminating the categorized low-grade lumber together to form a cant. Warp defects such as bow, twist and crook are also offset in the arrangement of the cant and are straightened through the clamping and bonding process. The cant is then re-sawn to produce new, laminated wood products of a higher grade, each new laminated wood product including portions of the original lumber.
