in which the coupling is specially adapted to constant velocity-ratio

Full Title

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slideably connected > in which the coupling is specially adapted to constant velocity-ratio
