We report here the results, to date, of our monitoring of northern WR stars. New orbits have been published for the short period binaries HD 193576 and HD 214419. Of particular interest are two long period binaries with fairly eccentric orbits, HD 190918 and HD 193793. A new orbit has been determined for HD 190918. We are currently analysing spectra obtained over one cycle of the 7.9 year period of HD 193793. Other stars on our primary target list include HD 192163, HD 192641, and HD 193077.
