    摘要: A computer implemented method, apparatus, and computer usable program product for symmetric and anti-symmetric control of aircraft flight control surfaces to reduce wing-body loads. Commands are sent to symmetrically deploy outboard control surfaces to shift wing air-loads inboard based on airplane state and speed brake deployment. Surface rate retraction on a wing with peak loads is limited to reduce maximum loads due to wheel checkback accompanied by utilization of opposite wing control surfaces to retain roll characteristics. Airloads are shifted inboard on a swept wing to move the center of pressure forward, thereby reducing the tail load required to perform a positive gravity maneuver. In a negative gravity maneuver, speed brakes are retracted, thereby reducing the positive tail load and reducing the aft body design loads. High gain feedback commands are filtered from wing structural modes above one hertz by a set of linear and non-linear filters.

    摘要: Inserting systems and methods are provided for use in sheet processing. The inserting systems and methods provide improved handling of sheet articles during processing. Sheet articles can be advantageously and efficiently advanced in separate stacks and later combined for insertion into an envelope. For insertion into an envelope, the mouth of the envelope can be selectively variably opened depending upon the amount of insertion material to go into the envelope where the amount an envelope is to be opened can be based upon processing or job information. Sheet articles can be registered and aligned to facilitate processing efficiencies. Sheet articles with creases, such as envelopes with mouth flaps, can be processed through a roller system to bend the crease so that the flap of the envelope assumes a desired position for subsequent processing. Additionally, sheet articles can be processed through a staging station with increased capacity for sheet processing.

    摘要: A dock plank assembly formed from at least two elongated polymer plastic plank having a first support end, a second support end, a top surface for walking on, and an integral longitudinal web therein for providing rigidity and support to the planks with the webs having an opening therein for receiving a free-span rib with the free-span rib spaced from the support ends of the planks and extending transversely through the opening in the webs of the plank to provide rigidity and additional individual support for each of said planks and for providing coactive support for the planks as a unit to thereby maintain adjacent planks in surface walking condition with respect to one another to prevent a user from tripping over protruding edges on the planks.
