I have various sambo books, and throws, takedowns, leglocks, armlocks, etc, and the names of the techniques are self-explanatory.
For example, Osoto nage is labeled as "Throw Backwards (First variant)".
Ippon Seoi Nage is labeled as "Throw forward (Second variant)".
A turnover for when your oponent is turtling and you go for an armbar, is labeled as "Turnover with transition to elbow lock".
When you are in kesa gatame and go for an armlock using your legs, is labeled as "Transition from cross-hold to an elbow lock across (your) femur".
A straight ankle lock is labeled as "Jamming/pinching the Achilles tendon".
Throws in general are known as "brosok" (бросок

.
For example, kata-guruma (fireman's carry) is labeled as "Windmill throw over the head" (бросок мельиницей на голобу

.
And so on.
If you are searching for the term for a particular technique or throw i could search it.
