  • Patent number: 4496410
    Abstract: First and second bodies of heat recoverable polymeric material are fusion bonded together with their directions of recovery at an angle to each other, the bond preferably being cross-linked after bonding to enable the resulting article better to withstand the recovery forces encountered in use. The invention is especially useful for making wraparound tubular enclosures for "T"'s and bends which enclosures in use will recover radially about two tubular axes.

  • Patent number: 4069910
    Abstract: Method for positioning lumber being transported on a conveyor prior to sorting or other similar processing, comprises centering the lumber intermediate its ends on the conveyor, reducing the number of conveyor lines required. The apparatus includes a first displacement member, for laterally even ending the lumber in a first direction, and a sensing member, for sensing the length of the lumber relative to the plane of the even ending. The lumber then is displaced laterally in a second, 180.degree. opposed, direction by a second displacement member until lumber engagement members, upon signal of the sensing member, selectively stop each piece of lumber at a particular transverse position on the conveyor corresponding to the length of that piece of lumber. The lumber engagement members comprise continuous chains interposing the lines of the conveyor and having segmented stops pivotally mounted thereon.
