Application No. 08/888,005
reference teaches that a Cardan (universal) joint, which does
provide a positive drive, alternatively can be used
(translation, page 3). Shafts 1 and 2 of the French reference3
constitute the first and second drive members recited in the
claims, which are connected by the rotatable drive member in
such a fashion, when used with a Cardan joint, as to transmit
the rotary motion of the first drive member to the second while
allowing flexing of the drive members with respect to one
another.
3See, for example, Machinery’s Handbook, 23rd Edition,
page 2218, provided by the appellant as an appendix to the
Brief, which states that a Cardan drive is merely another name
for a universal joint or Hooke’s coupling.
