Abstract
Abstract Device for ionizing a material, comprising a tube open at its two ends, and wherein first end of the tube is heated to a temperature permitting the ionization of the material, the second end of the tube being kept at a relatively low temperature, so as to produce a temperature gradient between the ends of the tube and wherein the material is introduced into the tube by the second end thereof, whereat the ionization of the material is also checked.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A device for thermally ionizing a solid material, comprising a tube open at its first and second ends, means for heating the first end of the tube to a temperature to affect thermal ionization of said material, the second end of the tube being kept at a relatively low temperature, so as to produce a temperature gradient between the said ends of the tube and means for introducing the material into the tube by the second end thereof comprising, a rod, at one end of which is deposited said material, and means for displacing said rod in a controlled manner within the tube, and means for detecting the resultant thermal ionization of the material.
Claim 2
Independent Claim
114 words
A device for thermally ionizing a solid material, comprising a tube open at its first and second ends, means for heating the first end of the tube to a temperature to affect thermal ionization of said material, the second end of the tube being kept at a relatively low temperature, so as to produce a temperature gradient between the said ends of the tube and means for introducing the material into the tube by the second end thereof comprising, a rod, at one end of which is deposited said material, and means for displacing said rod in a controlled manner within the tube, and means for detecting the resultant thermal ionization of the material.
Claim 3
Dependent Claim
34 words
A device according to claim 1, wherein the means for displacing the rod within the tube comprises a nut-screw system, whereof one of the elements is fixed and the other integral with the rod.
Claim 4
Dependent Claim
25 words
A device according to claim 1, wherein the said one end of the rod has a point, on which the material is deposited by electrodeposition.
Claim 5
Dependent Claim
29 words
A device according to claim 1, wherein the said end of the rod has a recess, in which is placed an ion exchange resin ball fixing the said material.
Claim 6
Dependent Claim
22 words
A device according to claim 1, wherein the means for heating the first end of the tube comprises an electron bombardment device.
Claim 7
Dependent Claim
41 words
A device according to claim 5, wherein the electron bombardment device comprises a coil surrounding the first end of the tube, means for supplying electricity to the coil and means for applying a potential difference between the coil and the tube.
Claim 8
Dependent Claim
25 words
A device according to claim 1, wherein the tube is mounted by its second end on an interchangeable fixed plate made from a conductive material.
