Method and device for verifying that a given insulative element conforms to a reference insulative element
First Claim
1. Method of verifying that a given insulative element conforms with a reference insulative element, comprising the steps of:
- emitting a primary beam of electrons impinging on said given insulative element,receiving a secondary beam of electrons returned by said given insulative element in response to emission of said primary beam of electrons, andcomparing a curve as a function of time of the electrical current of said secondary beam received with a curve as a function of time of a reference electrical current to establish whether or not said given insulative element conforms to a reference insulative element.

Abstract
A method of verifying that a given insulative element conforms with a reference insulative element, comprising the steps of: emitting a primary beam of electrons impinging on the given insulative element, receiving a secondary beam of electrons returned by the given insulative element in response to emission of the primary beam of electrons, and comparing a curve as a function of time of the electrical current of the secondary beam received with a curve as a function of time of a reference electrical current to establish whether or not the given insulative element conforms to a reference insulative element.

3. Method of sorting insulative material granules, comprising the steps of:
-
emitting a primary beam of electrons impinging on each of said granules, receiving a secondary beam of electrons returned by each of said granules in response to emission of said primary beam of electrons, comparing a curve as a function of time of the electrical current of said secondary beam received with a curve as a function of time of a reference electrical current associated with a reference granule, and ejecting granules selectively in accordance with a negative result of comparing said curve as a function of time of said electrical current of said secondary beam received and said curve as a function of time of said reference electrical current associated with said reference granule. - View Dependent Claims (4, 5, 6, 7, 8)
