Abstract: Heavy density honeycomb structures which include alternating layers of primary corrugated sheets and bisector sheets which are bonded together. The primary corrugated sheets are offset so that the bisector sheets are bonded to the corrugated sheet nodes so that the upper and lower bonding locations on each bisector sheet are displaced from each other. This displacement provides flexibility regions in the bisector sheets which enhance the formability of the heavy density honeycomb. The displaced node configuration is useful for enhancing thermal formability of both metallic and non-metallic honeycomb structures. The offset configuration is used with both substantially flat bisector sheets and corrugated bisector sheets.

Abstract: An animal litter and storage box device is presented which allows an operator to clean all solid animal waste from litter material with a simple two step motion. The operator has no contact with the animal waste and there are no substantial moving parts or complex motion patterns that are required to operate the device. The device includes a bottom tray, a cover member having a waste chute which fits over the bottom tray, and a slide rail separator contained within the device that is capable of separating animal waste from litter material. The animal waste and litter material mixture is moved through the slide rail separator by lifting one end of the device. The solid animal waste is separated by the slide rail separator and rolls into a waste storage bag attached to the waste chute. The reusable litter which passes through the slide rail separator is contained within the device. The device is lifted again to redistribute the cleaned litter.
