AbstractAbstract
[en] This invention relates to an improved wide-range radiation gage having a controlled-gain photodetector for determining a material property. Hereinafter, the invention is described with reference to accurately measuring a wide range of steel plate thicknesses, or steel strip thicknesses, in a hot steel rolling mill which normally produces a steel product under variable operating conditions. However, it will become apparent that the invention is equally applicable to gaging other materials, and other properties such as weight per unit area or density, and to other industrial installations as well as to a variety of laboratory apparatus

AbstractAbstract
[en] An apparatus is disclosed for determining the depth of a radiation source within a body of material utilizing a radiation source holder moving the radiation source within the body. A plurality of switches have contacts that are fixed in relation to the movement of the radiation source within the material. Trigger means activates a particular switch at a preselected depth of the radiation source. Means for indicating the activation of a switch would thus produce a signal as a representative of the depth of the radiation source

AbstractAbstract
[en] This invention concerns a real time technique for analyzing a gas flow moving through a hollow body such as a turbomachine, for obtaining three-dimensional information on the path taken by the gas when it passes through the motor. The difficulties to be overcome are constituted by the rate at which the gases move in the motor, the spreading of the gas flow in the body and the fact that the tracer employed in this analysis contaminates the exhaust gases, and possibly some of the motor, thereby leading to possible pollution hazards. This invention overcomes these troubles by using isotopes specially chosen for their short half life and the high radiation energy they generate, and by ensuring that the irradiation of the tracer substance occurs so as to produce an activity in the isotopes that is as great as possible and at the same time so as to enable the tracer to be injected in the motor as from the irradiation chamber for a very short period. The isotopes can be produced by bombardments of neutrons or by charged particles on to appropriate targets. A cyclotron is preferred as a source of charged particles

La presente invention concerne une technique d'analyse en temps reel d'un courant gazeux circulant dans un corps creux tel qu'une turbomachine pour obtenir l'information en trois dimensions de la piste suivie par le gaz quand il traverse le moteur. Les difficultes a surmonter sont constituees par la vitesse a laquelle les gaz se deplacent dans le moteur, la diffusion du courant gazeux dans le corps et le fait que le traceur utilise pour cette analyse contamine les gaz d'echappement et, eventuellement, des parties du moteur, ce qui peut entrainer des risques de pollution. La presente invention surmonte ces difficultes en utilisant des isotopes choisis specialement pour leur courte demi-vie et la forte energie des radiations qu'ils produisent, et en faisant en sorte que l'irradiation du materiau traceur se deroule a la fois d'une maniere produisant une activite dans l'isotope aussi importante que possible et d'une maniere permettant d'injecter le materiau traceur dans le moteur a partir de la chambre d'irradiation pendant une periode tres courte. Les isotopes peuvent etre produits par des bombardements de neutrons ou de particules chargees sur des cibles appropriees. On prefere une source de particules chargees constituee par un cyclotronOriginal Title
