Abstract: A system designed to reduce the recoil of any ball and powder type weapon such as guns, rifles, cannons or the like is disclosed. In a ball and powder type weapon the bullet or shell is propelled out of the barrel by the high pressure created by the explosion of the powder. Not only is the bullet or shell propelled out of the barrel but the air and other hot gasses are also jetted out of the barrel. Due to the fact that the air and other hot gasses are jetted out of the barrel, a vacuum is created in the barrel. After the shell or bullet and the hot gasses are jetted out of the barrel, air from the outside due to atmospheric pressure rushes back into the evacuated barrel and it is this rush of air back into the barrel that is the major cause of recoil in a ball and powder type weapon. The system of this invention reduces the recoil caused by this rush of air back into the barrel by providing a plurality of chambers that communicate with the bore of the weapon through separate channels or ports.

Abstract: A method and apparatus for increasing the production of tuber-producing plants per unit area is disclosed. In accordance with this invention, a seed-tuber is planted in soil that is contained in a first box or frame unit. As the plant grows it develops new leaves and axil-buds. When the plant reaches a given height, which is different for different plants, a new layer of soil is added to the first box or frame unit. The new layer of soil does not completely cover the plant. Instead, a layer of soil is added such that the apical meristem is located at the soil surface or about one cm. below the soil surface. As the plant continues to grow another new layer of soil is again added in the manner described. When the level of the soil approaches the top of the first box or frame unit, a second box or frame unit designed to fit on top of the first box or frame unit is placed on top of the first box or frame unit.
