Abstract: A torsion isolator assembly (30) for reducing driveline torsionals includes a vane damper (36) including improved valving (40d,40e) for increasing the damping factor of the damper, improved spiral springs (32,34 or 80,82) for reducing spring stress primarily due to centrifugal forces, and cam surfaces (44d,44c) for further reducing spring stress due to centrifugal forces.

Abstract: A laminated or multiple-ply container structure comprising an inner wall of a substantially rigid material and an outer wall of a thin, generally pliant material, such as a glossy finished paper, adhesively fastened thereto by a suitable adhesive or glue. Formed in the outer wall of the container, as an integral component thereof, and through the intermediary of a tear outline constituted of perforations extending through at least the outer ply or wall is a section constituting a readily removable or peelable coupon-like panel, with the peeling off of the panel adapted to be effectuated without adversely affecting the integrity of the container structure or necessitating the use of special cutting instruments or tools.

Abstract: In cartons made from laminated packaging material wherein a peelably removable section of the outer ply is defined by a weakened tear line and said section is unadhered to the substrate, resistance to unauthorized tampering or removal of such section from said container is achieved by utilizing a water soluble adhesive as a laminant and including a border area of said section at the starting point of the tear outline within the area of adherence by said laminant to thus require application of moisture to said border area to dissolve said adhesive at said area before the tearing away of such section can be accomplished.

Abstract: A laminated or multiple-ply structure comprising an inner wall of a substantially rigid material and an outer wall of a thin generally pliant material, such as a glossy finished paper, adhesively fastened thereto by a suitable adhesive or glue. A plurality of artifact receiving pockets are formed in the thin outer wall of the container, with each pocket being formed through the intermediary of a suitable perforation configuration formed therein. Each perforation configuration includes slits penetrating through the outer wall material and defining a pocket by a plurality of discontinuous slits extending along the semicircular peripheral edge of the pocket.
