Abstract: A perforated metal honeycomb structure is described. The perforated metal honeycomb structure may include a metal honeycomb structure having a plurality of laser-drilled holes wherein at least some of the plurality of holes are non-uniform in second, shape, and/or spacing between holes. In another embodiment, the perforated metal honeycomb structure may include an array of intercellular holes between hexagonal cells in the honeycomb structure. The array of intercellular holes may include at least a first hole and a second wherein the first and second holes are different from each other.

Abstract: In one embodiment of the present disclosure, a method of manufacturing perforated metal honeycomb material includes: printing a roll of metal foil with adhesive; laser perforating the roll of metal foil to provide a plurality of holes in the metal foil; sheeting the printed and perforated roll of metal foil into a plurality of stacked sheets; and laminating the sheets of metal foil into a honeycomb before expansion block (HOBE). In another embodiment of the present disclosure, a perforated metal honeycomb structure includes a metal honeycomb structure having a plurality of laser-drilled holes wherein at least some of the plurality of holes are non-uniform in size, shape, and/or spacing between holes.

Abstract: A rocker arm may include a first arm defining a first longitudinal bore and a second arm defining a second longitudinal bore. The rocker arm may house a locking assembly including a first lock pin located within the first longitudinal bore, an actuation pin extending through a radial passage in the rocker arm and engaged with the first lock pin, and a first biasing member engaged with the first lock pin and urging the first lock pin toward the actuation pin and biasing the actuation pin radially inward. An actuation assembly may be engaged with the actuation pin and linearly displaceable between first and second actuation positions. The first and second arms may be rotatable relative to one another when the actuation member is in the first actuation position and may be fixed for rotation with one another when the actuation member is in the second actuation position.

Abstract: An apparatus and method for automatically positioning a plurality of suction devices over the throat of envelope to lift the throat.

Abstract: A method and an apparatus for opening an envelope for document insertion in a document inserting system. The apparatus includes: an air chamber having a first end and an opposing second end and an inlet in the first end; a piston movably located in the air chamber for dividing the air chamber into a first chamber near the first end and a second chamber near the second end; a suction cup operatively connect to the air inlet to pick up the throat of an envelope; a spring operatively connect with the piston; and a cam operable at a first position to compress the spring and to keep the piston near the first end, and at the second position to release the spring which urges the piston to move away from the first end and expand the first chamber, thereby creating a suction force for the suction cup.

Abstract: A buckle accumulator including an input feed system, an output feed system located downstream in a path of travel from the input feed system, a receiving space located adjacent the path of travel between the input feed system and the output feed system, and a deflector. The input feed system feeds a plurality of sheets one at a time in a path of travel into the buckle accumulator. Each of the plurality of sheets has a leading edge and a trailing edge. The output feed system feeds a stack of sheets out of the buckle accumulator. Generally, the lead edge for each of the plurality of sheets is substantially unrestrained between the input feed system and the output feed system. The receiving space accepts the plurality of sheets one at a time to create the stack. The deflector is mounted in proximity to the receiving space for selectively actuating between a first position out of contact with a first sheet previously accumulated in the receiving space and a second position in contact with the first sheet.
