Appeal 2007-1101
Application 10/248,535
probe 216 in Figure 4 of the second embodiment, and probe 316 within the
third embodiment in Figure 5 has elements disclosed which are operatively
connected to the piston for fluctuating the fluid within the cavity as in
independent claim 1, permit selective activation of elements associated with
the piston within each of these probes such as to fluctuate the fluid in the
cavity as well as having elements which are selectively positioned within a
cavity for fluctuating the fluid in the same cavity as recited respectively in
independent claims 1, 12, and 30 on appeal.
The actuating means of the Abstract in Ciglenec is also utilized within
the Summary of the Invention discussion at column 3, lines 31 through 56,
to perform this function. Within Figure 2 and the various parts of Figure 3
there is no dispute that the probe 16 includes a piston 51, best shown in
Figure 3C, and labeled as pin 51 within the teachings of this reference.
Additionally, there is disclosed a piston 70 and hydraulic valves 61, 63
which functionally operate by means of hydraulic fluid passage 29 in the
various figures according to the hydraulic system 28 in Figure 2. The piston
70 within the probe 16 is shown in Figure 3A in a withdrawn, retracted
position and a piston 51 within it is shown in a forward position. Figure 3B
shows the piston 70 in an advanced or forward position, again with the
piston 51 within it in a forward position. The same may be said of Figure
3C. In Figure 3D, the piston 70 remains in the forward position and the
piston 51 within it has been moved back within piston 70 such as to permit
the pressure of the formation to be measured by the pressure sensor 54
according to the discussion of Figure 2 beginning at column 5. Through the
discussion of the various portions of Figure 3, the piston 51 within the piston
70 operates in an oscillatory manner. They start in a retracted position, are
