Reissue Application No. 07/837,588
[36] 85. In [A] a method of operating a laundry
machine having a container for a wash load of soiled
fabrics in wash water and a reciprocatable agitator
in said container, an electric motor having a rotor
for driving said agitator, setting means [to set]
for setting a desired rate and amplitude of
oscillating rotation of said agitator, electronic
control means for controlling [the] a supply of
electrical power to said electric motor in one of a
plurality of sequences of operation selected from an
agitation sequence and a spinning sequence, [said
method including] the improvement comprising the
steps of:
a setting a selected one of said
plurality of sequences of operation so that said
agitator is driven in oscillating rotation during a
wash phase in a sequence of washing operations,
b sensing [the] resistance to
oscillation of said agitator due to the wash load in
said container,
c [and] adjusting the power supplied to
said electric motor so that a selected rate of
removal of soil from said soiled fabrics is
substantially achieved, and
[37. A method as claimed in claim 36 which
includes the step of] d sensing load on said
[motor] rotor by measuring the time the [motor]
rotor takes to run down in speed from a power off
condition to a speed condition in which [the motor
direction may be reversed] application of power to
the motor will cause reversal of rotation of the
rotor constituting a condition for reversal.
The appellant admits, “claim 85 is similar to nonelected
claims 36 and 37 ....” (Reply Br. at 5.) This is an
