Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
120 words
In a method for filling a reloader with dry bulk particulate material under the influence of a vacuum and thereafter emptying said reloader of said dry bulk particulate material by air pressure, from a blower, the improvement of: filling said reloader with dry bulk particulate material; and simultaneously introducing air into said reloader during said filling step at a different location than the filling said reloader with dry bulk particulate material, said air being at a greater pressure than the air inside said reloader for mixing said air and said dry bulk material to form a homogenous mixture in said reloader; whereby said homogenous mixture flows at a faster rate under the influence of said blower to empty said reloader.
Claim 2
Dependent Claim
120 words
In a method for filling a reloader with dry bulk particulate material under the influence of a vacuum and thereafter emptying said reloader of said dry bulk particulate material by air pressure, from a blower, the improvement of: filling said reloader with dry bulk particulate material; and simultaneously introducing air into said reloader during said filling step at a different location than the filling said reloader with dry bulk particulate material, said air being at a greater pressure than the air inside said reloader for mixing said air and said dry bulk material to form a homogenous mixture in said reloader; whereby said homogenous mixture flows at a faster rate under the influence of said blower to empty said reloader.
Claim 3
Dependent Claim
31 words
The invention as defined in claim 1 and further including the step of dispersing said air throughout said reloader to form said homogenous mixture of air and dry bulk particulate material.
