Previously separated definition

Previously separated. (0 1) means the application of any process intended to increase the concentration of the controlled isotope.
Previously separated. (Category 1) means the application of any process intended to increase the concentration of the controlled isotope; “primary flight control” (Category 7) means an “aircraft” stability or manoeuvring control using force or moment generators, i.e. aerodynamic control surfaces or propulsive thrust vectoring; “principal element” (Category 4), as it applies in Category 4, is an element the replacement value of which is more than 35% of the total value of the system of which it is an element. Element value is the price paid for the element by the manufacturer of the system, or by the system integrator. Total value is the normal international selling price to unrelated parties at the point of manufacture or consolidation of shipment; “production” (GTN, NTN, All Categories) has the same meaning as in the Act; “production equipment” (Categories 1, 7, 9) means tooling, templates, jigs, mandrels, moulds, dies, fixtures, alignment mechanisms, test equipment, other machinery and components therefor, limited to those specially designed or modified for “development” or for one or more phases of “production”; “production facilities” (Categories 7, 9) means “production equipment” and specially designed software therefor integrated into installations for “development” or for one or more phases of “production”; “program” (Categories 2, 6) means a sequence of instructions to carry out a process in, or convertible into, a form executable by an electronic computer; “pulse compression” (Category 6) means the coding and processing of a radar signal pulse of long time duration to one of short time duration, while maintaining the benefits of high pulse energy; “pulse duration” (Category 6) means the duration of a “laser” pulse, or the time between the half-power points on the leading edge and trailing edge of an individual pulse; “pulsed laser” (Category 6) means a “laser” having a “pulse duration” that is less than or equal to 0.25 seconds; “quantum cryptography” (Category 5) means a family of techniques for the establishment of shared key for “cryptography” by measuring the quantum-mechanical properties of a physical system (including thosephysical properties explicitly governed by quantum optics, quantum field theory or quantum electrodynamics);
