meet the limitations in independent claims 10 and 16 relating
to the silage density control means. These limitations
require, inter alia, that the control means include a
plurality of horizontally spaced-apart density bars which are
secured to an elongated, horizontally disposed, rotatable
shaft for selective movement within the flow of silage
material. Although Cox’s pivot panels 140 correspond
generally to the claimed density control means, they lack the
spaced-apart bar configuration specified by claims 10 and 16.
As a result of this difference in configuration, Cox’s pivot
panels 140 also fail to control silage density in the
particular manner set forth in these claims.
Eggenmuller discloses a machine and method for pressing
loose feed material into a mass having a desired density. The
machine 2 includes “a receiving chamber 3 in which pressing
tools 4 are arranged which press the feed into a forming
channel and consists of a carriage with rollers 6. The
forming channel 5 has in cross-section the shape of the mass
of material 7 to be produced” (column 5, lines 9 through 13).
As depicted in Figures 1 through 3, the pressing tools 4
appear to consist of a plurality of horizontally spaced-apart
