Abstract
Abstract An apparatus for analyzing certain properties of an object with a beam of radiation capable of emitting fluorescent x-rays by (1) aligning a pivotally mounted radiation-emitting generator with a pivotally mounted radiation detector relative to a specific point on the object by providing for a beam of visible light to be separately directed from the generator and detector, (2) generating and projecting a beam of radiation against a selected portion of the object, which includes the points to be analyzed, causing the object point to become stimulated to emit its own radiation, (3) detecting this object-emitted beam of radiation by the detector and (4) analyzing the spectrum of the detected beam.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
222 words
A method of analyzing an object with a beam of ionizing radiation comprising the steps of: (a) aligning an ionizing radiation-emitting generator, mounted in a generator housing, with an ionizing radiation detector, mounted in a detector housing, emitting a beam of visible light from a visible light source mounted in said generator housing and directing said beam of visible light with a generator beam directing means onto a point on said object, emitting a beam of visible light from a light source mounted in said detector housing and directing said beam of visible light with a detector beam directing means onto said same object point, and pivoting said generator and said detector with respect to each other in a common plane until said detector visible light beam coincides with said generator visible light beam on said object point; (b) de-energizing said generator and said detector visible light sources and removing said generator and said detector beam directing means when said generator light beam coincides with said detector light beam; (c) generating a beam of ionizing radiation from said generator and projecting said beam onto said object including said point of coincidence; and (d) detecting a beams of ionizing radiation with said detector where said beam is emitted by said point of coincidence when said generator radiation beam contacts said point of coincidence.
Claim 2
Independent Claim

A method of analyzing an object with a beam of ionizing radiation comprising the steps of: (a) aligning an ionizing radiation-emitting generator, mounted in a generator housing, with an ionizing radiation detector, mounted in a detector housing, emitting a beam of visible light from a visible light source mounted in said generator housing and directing said beam of visible light with a generator beam directing means onto a point on said object, emitting a beam of visible light from a light source mounted in said detector housing and directing said beam of visible light with a detector beam directing means onto said same object point, and pivoting said generator and said detector with respect to each other in a common plane until said detector visible light beam coincides with said generator visible light beam on said object point; (b) de-energizing said generator and said detector visible light sources and removing said generator and said detector beam directing means when said generator light beam coincides with said detector light beam; (c) generating a beam of ionizing radiation from said generator and projecting said beam onto said object including said point of coincidence; and (d) detecting a beams of ionizing radiation with said detector where said beam is emitted by said point of coincidence when said generator radiation beam contacts said point of coincidence.
Claim 3
Dependent Claim
23 words
A method in accordance with claim 1 wherein the steps of generating a beam of ionizing radiation comprises the step of generating x-rays.
Claim 4
Independent Claim
209 words
An apparatus for analyzing an object with a beam of ionizing radiation comprising: a generator, mounted in a housing, for emitting a beam of ionizing radiation along a radiation path in the direction of said object to be analyzed; a detector, mounted in a housing, for detecting ionizing radiation along a radiation path; means for aligning said generator radiation path and said detector radiation path each, with respect to the other, and both relative to a point on said object to be analyzed such that a beam of ionizing radiation projected onto said object, including said point of said object, by said generator along said generator radiation path in the direction of said point, will stimulate said point on said object to emit ionizing radiation along said detector radiation path, said aligning means including a generator aligning means, having a visible light source mounted in said generator housing and means for directing light from said generator visible light source along said generator radiation path and onto said object including said point, and a detector aligning means, having a visible light source mounted in said detector housing and means for directing light from said detector visible light source along said detector radiation path and onto said object including said point.
