Abstract: A method and system are disclosed for the implementation of a weakened privacy channel. This is achieved through use of a weakened symmetric cryptographic algorithm called commercial data masking. The masked text is created from clear text at one system and may to transported electronically to another system where the masked text may be unmasked to produce the clear text. The reason to use the commercial data masking algorithm for data privacy is that it is exportable to organizations to which products which contain the Data Encryption Algorithm when used for data privacy are not exportable. In addition, a method and system is disclosed by which the key when used for commercial data masking may be transformed into a key that may be used with the Data Encryption Algorithm.

Abstract: NMR MAGNET ASSEMBLY WITH POLE FACE PARALLELISM ADJUSTMENT A nuclear magnetic resonance (NMR) magnet assembly includes two pole faces spaced to provide a gap in which is established a uniform magnetic field. The pole pieces have pole faces that are flat and parallel. The pole pieces are mounted on support plates one of which is fixed and the other of which is movable about a pivot point with two degrees of freedom of movement in response to adjustment of two adjustable mechanisms. Each adjustment mechanism includes a differential screw that produces a transverse movement and a longitudinally inclined pin or pins that translates such transverse movement into a much greatly reduced longitudinal movement. The combination of a differential screw and inclined pin provides a very fine adjustment of the parallelism of the pole faces. Each mechanism further includes means for providing a coarse adjustment.
