Abstract: A method and a non-transient computer readable medium for sorting orders to be run on a multi-section slitter/scorer at a corrugator dry end includes collecting specifications of orders in current, prior, and/or subsequent paper group queues. Run times and slit/score head recovery times for orders in the current paper group queue are calculated using the specifications. Those orders for which recovery time exceeds run time are flagged as short orders. For a given short order, pairs of preceding and following orders that would require recovery times less than the short order's run time are determined and flagged as potential bracketing pairs. The current paper group queue is searched to determine if a bracketing pair can be formed from its orders, and if so, the orders in the current paper group queue are reorganized such that the orders in the bracketing pair immediately precede and follow the given short order.

Abstract: A processed fiber is used to distribute energy from an electromagnetic (EM) energy source to a material in which the fiber is embedded. The electromagnetic energy source supplies electromagnetic energy to the fiber and the fibers emit portions of the EM energy along the length of the fiber. The sealant material absorbs a quantity of the electromagnetic energy sufficient to cure the sealant material and propagates excess electromagnetic energy through the sealant material without significant additional absorption. This prevents the sealant material from over-curing. Additionally, a fully cured material can be used to generate thermal energy and thereby serve as a heat blanket that can be used to de-ice aircraft.

Abstract: The invention is a method of fluting corrugating medium which can be formed in conventional or unconventional flute configurations. The method employs at least one additional corrugating roll in addition to the usual two. The first pair of rolls create initial flutes in the medium. Initially fluted medium is then transferred to a third roll of lesser flute pitch than the first rolls. In this manner the initially created flutes can be reformed into configurations not possible using conventional systems. A fourth roll can be used to achieve additional flute pitch reduction. Using this method flutes with very sharply angled tips can be formed. Other embodiments enable formation of less conventional cross sectional configurations such as flutes with asymmetric patterns.
