Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
131 words
Apparatus for collecting and storing empty aluminum containers and issuing payment for containers collected, comprising: preselection means for exposing a crushed or non-crushed container offered by a customer to an electromagnetic field for identifying whether said container is substantially aluminum without establishing direct electrical contact with said container, said preselection means including a container access area configured to accomodate both crushed and non-crushed containers for exposure to said field; means for accepting only a container identified by said preselection means as being substantially aluminum, independent of the configuration of said container; coin-dispensing means responsive to said preselection means for dispensing coins in return for containers having a substantially aluminum composition; means cooperating with said accepting means for crushing said containers; and means for storing crushed containers received from said crushing means.
Claim 2
Dependent Claim
131 words
Apparatus for collecting and storing empty aluminum containers and issuing payment for containers collected, comprising: preselection means for exposing a crushed or non-crushed container offered by a customer to an electromagnetic field for identifying whether said container is substantially aluminum without establishing direct electrical contact with said container, said preselection means including a container access area configured to accomodate both crushed and non-crushed containers for exposure to said field; means for accepting only a container identified by said preselection means as being substantially aluminum, independent of the configuration of said container; coin-dispensing means responsive to said preselection means for dispensing coins in return for containers having a substantially aluminum composition; means cooperating with said accepting means for crushing said containers; and means for storing crushed containers received from said crushing means.
Claim 3
Dependent Claim
37 words
