  The search was performed for cataclysmic variable stars with outlying
infrared magnitudes in USNO-B1.0 catalog. The selection was limited to objects
in the Northern hemisphere with (B1-R1) < 1 and (R2-I) > 3.5. The search method
is described, and the details on individual stars are given. In total 27
variable objects were found with 20 being the previously known ones and 7 - new
discoveries. 4 of newly found variables are dwarf novae, while the remaining 3
- pulsating red variables of Mira or semi-regular types, including a heavily
reddened one in Pelican nebula. The correct pulsation period is determined for
two stars discovered by other researchers, and the dwarf nova nature is
confirmed for another object previously suspected as such. The perspectives of
the proposed search technique in the framework of Virtual Observatory are also
discussed.
