TEXT: In order to produce pure VC1 3 (used ir. the production of metail-'c
vanadium), the initial product is treated several times with an organic
nonpolar solvent (CC1 41 CS2 or gasoline), and the solution of oxychlorides
and chlorides of vanadium with higher valencies separated from the
undissolved VC1 3' The organic phase is then shaken up with water, convert-
ing the vanadium compounds into an aqueous solution. The regenerated solvent,
is returned for further use, and the compounds of vanadium are precipitated
from the aqueous phase and reprocessed into VC13. [Abstracter's note:

The Fourier Transform in the Theory of.Difference Equations and its
Applications, Arch. Mech. Stos., 11 (1959) 349-381) is extended.to
the solution.-of..the.Wiener-Hopf problem in the one-dimensional ca.",;
The problem is defined.as follows: M denotes the set of all integer
R denotes the linear space of all bounded complex functions defined
on M; R+ denotes the subspace such that f(n) a 0 for n < 0; f+(n) X
0 and f__(n) u f(n) if n < 0; Wn) - f(n) and f__(n) - 0 if n >, 0;
