CB is not a brand trademark (no slam intended, just clarification), it stands for "Conical Bullet". At one time there used to be several very low powered .22 Rimfire loads. Two of these were BB Caps, and CB Caps. The BB cap obviously was a round bullet with the BB standing for Bulleted Breech Cap and is one of the oldest successful self contained cartridge. The CB caps are a conical bullet which is similar in shape to a regular .22 LR bullet.
CB caps are still alive and well, in fact they have been improved. CCI manufactures a CB Long which obviously provides sufficent cartridge over all length to allow these to feed through autoloaders and other firearms that will not feed shorts (they feed but usually don't provide enough oomp to cycle the action, you have to manually cycle the action).
According to Cartridges of the World, 9th Edition CB caps were avialable in 16, 18, and 20 grain balls with muzzle velocities of 750, 780, and 780 fps. CB caps are available in 29 and 30 grain bullets with a muzzle velocity of 725 and 727 fps.
The big selling point of CB caps is that when fired out of a .22 Rifle, they are almost silent. You can actually hear the bullet striking the target allowing backyard and basement fun.

You know the rest. In the books you have read
How the British Regulars fired and fled,
How the farmers gave them ball for ball,
From behind each fence and farmyard wall,
Chasing the redcoats down the lane,
Then crossing the fields to emerge again
Under the trees at the turn of the road,
And only pausing to fire and load.
