support (see page 7 in the brief) merely indicates that the
high torque wrench can be repeatedly activated until the bolt
is completely tightened to the required high torque. It
simply does not follow that repeated activation of the high
torque wrench will result in rotation of the drive head of at
least one revolution.
Claims 78 through 80, 87 through 89, 92 through 94, 96
through 98 and 101 through 103 recite negative limitations
which require that fluid flow is automatically diverted by the
fluid pressure activated valve member “without” the use of
strain gauges, solenoid valves or electronic pressure switches
(claims 78, 87, 92, 96 and 101), that fluid flow is
automatically diverted by the fluid pressure activated valve
member “without” the use of electricity (claims 79, 88, 93, 97
and 102), and that the low-torque motor directly engages,
“without” intermediate or intervening gears, the drive head
(claims 80, 89, 94, 98 and 103). Although the originally
filed disclosure does not expressly describe the fluid
pressure activated valve member 48 or the structural
connection between the low torque motor 40 and the drive head
29 in these terms, it does reasonably convey that these
