Newton powder

Basic types of extruders include axial end plate, radial screen, rotary cyhnder or gear, and ram or piston. For a review, see Newton [Powder Technology Pharmaceutical Processes, Chuha et al. (eds.), Elsevier, 391 (1994).]...

A point worthy of notice is that the force of explosion of the propelling powder is exerted equally upon the projectile and upon the gun in terms of Newton s Law of Action and Reaction. The backward acceleration of the gun, proportionally to its weight, is nearly the same as that of the projectile, and results in the phenomenon of recoil.

The simplest application of powder diffraction is to identify a crystalline phase. One merely runs the powder pattern of the solid and records either 29 values or rf-spacings or both. This information is given by the program and can be printed directly on the pattern. Then one may consult a database such as the JCPDS file. These initials refer to the JCPDS. As a result of the complexity of keeping pace with the ever growing fist of known phases, the operation grew and was renamed the International Centre for Diffraction Data (ICDD), headquartered in Newton Square, Pennsylvania.
