Abstract: A method for producing a missile nose cone is disclosed. The method consists of manufacturing a first missile nose cone from a first lot of polymeric material and determining a first rupture value. The method further consists of manufacturing a second missile nose cone from a second lot of polymeric material and determining a second rupture value of the second missile nose cone. Both first and second lots of material are mixed into a test batch with one another based on their associated rupture values. An evaluation missile nose cone is then manufactured from the test batch and a determination is made as to whether the evaluation missile nose cone has a desired rupture value. If a desired rupture value is not obtained, then the mixing and evaluation steps are repeated.

Abstract: A grinding adaptive control system and method is described which automatically determines the feed rate to maintain constant wheel sharpness without wheel breakdown. Wheel sharpness at a given feed rate is sensed by the steady state horsepower or normal force, the adaptive control progressively adjusts feed rate in response to changes in wheel sharpness until a steady state feed rate range is reached. Wheel sharpness will then remain essentially constant.

Abstract: A pneumatic press assembly 10 uses air pressure to power a piston 70 in a cylinder 52 through a power stroke. Springs 76, 78, 80, 82, 84, and 86 oppose the motion of the piston 70. A set of return springs (76 and 78) is effective over the entire stroke of the piston. The return springs are compactly mounted within the cylinder 52 between the bottom of the piston 70 and a shoulder 56 which extends radially inwardly from the cylinder wall. The shoulder also cooperates with a central portion 110 of the piston 70 to prevent rotation of the piston. A second set of springs (80, 82, 84, and 86) is effective only when the piston 70 is within a predetermined distance from the bottom of the power stroke. The second set of springs 80, 82, 84 and 86 is disposed between the bottom 230 of the cylinder 52 and a preload member 234. When the piston 70 approaches the bottom of its stroke, it contacts the preload member 234 which in turn compresses the springs 80, 82, 84, and 86 bringing the piston to a halt.
