Abstract: A method is provided for solid-propellant engines to be dismantled safely and in accordance with environmental standards having been scrapped. For each engine to be dismantled, it is mounted on a static test rig, immersed in a tank filled with water and started such that propellant is used up under the water.

The design of the heeled shoe manages defects in the natural shape of the foot, reducing any pain and the exacerbation of podiatric conditions and problems incurred from use of improper footwear. The insole/midsole combination broadly disperses the weight bearing across the entire base of the foot and takes pressure away across the metatarsals and toes, providing a comfort-level equivalent to a flat shoe. While disguising the insole/midsole combination and imitating the height and appearance of a higher heeled shoe, the anatomically designed heeled shoe ensures additional height, optimal comfort and health for the wearer.

Abstract: The footwear cushioning invention includes a floating elastic plate that stores and returns elastic energy to provide cushioning through deflection of the elastic plate. Cushioning is by energy return rather than the compression of a foam. Footwear cushioning utilizes a deflection plate integrated into the heel of the shoe for providing shock attenuation and energy absorption when a wearer impacts a hard surface with the shoe. The deflection plate can be carbon fiber because it increases energy return and minimizes energy loss. A cavity can be formed in a midsole of the shoe underneath the deflection plate to allow the plate to flex into the cavity when pressed down upon by a wearer's heel, thereby accepting the energy of a downward step. A post can be located in the center of the cavity underneath the deflection plate that allows support and minimizes excessive deflection of the deflection plate.
