Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A method of compacting batches of refuse into a refuse storage compartment having an opening at one end, a first panel mounted therein for movement away from said one end and a packing panel for packing refuse into said compartment through said opening, comprising: holding the first panel against movement away from said one end; moving the packing panel to pack a batch of refuse into the compartment at said one end thereof against the first panel; sensing the packing force exerted by the packing panel on said batch of refuse; and releasing the first panel for movement away from said one end when said packing force reaches a predetermined value sufficient to provide the desired compaction, said predetermined value remaining substantially constant for all degrees of compartment filling.
Claim 2
Independent Claim
129 words
A method of compacting batches of refuse into a refuse storage compartment having an opening at one end, a first panel mounted therein for movement away from said one end and a packing panel for packing refuse into said compartment through said opening, comprising: holding the first panel against movement away from said one end; moving the packing panel to pack a batch of refuse into the compartment at said one end thereof against the first panel; sensing the packing force exerted by the packing panel on said batch of refuse; and releasing the first panel for movement away from said one end when said packing force reaches a predetermined value sufficient to provide the desired compaction, said predetermined value remaining substantially constant for all degrees of compartment filling.
Claim 3
Dependent Claim
34 words
The method as claimed in claim 1, wherein the first panel is released for movement away from said one end in progressive steps, one step each time said packing force reaches said predetermined valve.
Claim 4
Dependent Claim
23 words
The method as defined in claim 1, further including the step of reestablishing said holding step following the performance of said releasing step.
Claim 5
Dependent Claim
25 words
The method as defined in claim 1, further including repeating said holding, moving, sensing and releasing steps in a plurality of cycles of said steps.
Claim 6
Dependent Claim
29 words
The method as claimed in claim 1, comprising the further step of moving the first panel toward said one end to force packed refuse out of the storage compartment.
