Title: Improvements in radiometric analysis
Inventor: STARNES PETER EDWARD
IPC: G01N23/223
Filed: 1967-10-27
Abstract: 1,259,771. X-ray fluorescence analysis. HILGER & WATTS Ltd. Jan.27, 1969 [Oct.27, 1967], No.49024/67. Heading G1A. In X-ray fluorescence analysis of a slurry, besides the fluorescence analysis measurement itself, separate measurements of absorption are carried out on the slurry so as to correct the fluorescence measurement for variations in the value of the sum (Áe + Áf) of the absorption coefficients for incident and fluorescent radiation respectively. One absorption measurement comprises measuring the absorption, by the slurry, of a beam of y -radiations in the energy range 600-3, 000 KeV. In this measurement the apparatus used may be similar to the absorption measurement device disclosed in Specification 1,103, 562 for measuring the density of slurry, and involves passing the beam through a column of the slurry. The other absorption measurement is carried out with a reflex or backscatter geometry set-up, Fig. 2, and utilizes a target D on the side of the sample cell C remote from the radiation source B which is mounted on the window of a detector A in shielded relation thereto. In this way, characteristic (fluorescent) radiation from the target (which is of the material to be determined in the sample) is absorbed by the slurry sample as it passes therethrough to the detector. In obtaining the latter measurement accurately, certain corrective measurements are necessary: the background radiation is measured, the target not being in position, Fig. 1 (not shown); also standardizing measurements using firstly, Fig. 3 (not shown) a standard absorber alone, and then, Fig.4 (not shown), the standard absorber plus the target, are carried out, this providing a calibration or standardization for each sample and thereby obviating the effects of drift in the detector circuitry which might occur during a sequence of measurements on sequential portions of the sample. The measurement carried out using reflex geometry is dependent on Áe and Áf. This measurement is combined with that for absorption of gamma rays to determine (Áe + Áf) which is then used in order to correct the main fluorescence measurement.

[Also in Division G6] A neutron radiography apparatus comprises in combination a housing, e.g. 2 for a neutron source, a collimator, e.g. 3 for neutrons, emitted by the source and a means, e.g. tank 1, for containing a neutron moderating material, e.g. oil, between the source and the collimator, the distance between the collimator and the source being variable by relative movement of the source and collimator, e.g. by moving collimator 3 in sliding joint 4, to allow variations in the thickness of the neutron moderating material between the collimator and source. There may be placed between the neutron source housing 2 and the collimator 3 a substance which is capable of undergoing fission with fast neutrons and a substance which is capable of fission with thermal neutrons. These substances are preferably the U238 Isotope and U235 Isotope respectively and may be rods 12 of uranium metal supported in stand 13.

Pressure rollers 9, connected by levers 11 to a pneumatic cylinder 12, engage recesses 10 on the housing and gearing 19 links the housing to the shaft of a flywheel 17; the whole forming an oscillating system whose natural frequency is selected to be as near as possible to the frequency of any pertubations acting on the chain by adjusting the damping force of the cylinder 12 and/or the moment of inertia of the flywheel. If the buckets encounter an immovable obstacle the housing will rotate to an extent that the rollers 9 will leave the recesses 10; in this case levers 12a, 13, will operate a switch 30 to exhaust cylinder 12 (allowing free rotation of the housing 8) and to turn off the motor 4. In further embodiments: a number of separate flywheels are mounted on the shaft 18 and each can be selectively engaged or disengaged from the shaft (Figs. 4, 5, not shown); the flywheel mass can be radially adjusted with respect to the shaft 18 (Fig. 6, not shown); and a motor and reduction gearing system can be provided on each side of the drum (Fig. 7, not shown).

In apparatus for feeding sheets one by one from the top of a pile S, Fig. 1, and wherein the front edge of each sheet as it is separated snaps over stops engaging the front corners of the pile, each corner stop 450 comprises a cap 455, Fig. 3, with a narrow ledge 457 sloping forwardly and outwardly relative to the pile and having a rearwardly - extending arched part with a helical edge 461. The cap 455 is formed at the top of an angle member 451, 453 which embraces the corner of the pile and the point 463 of the rearwardly-extending part of the cap lies in the plane of the side member 453. Due to the pressure of the sloping ledges 457 on the pile corners the sheets of the pile normally assume an upward transverse curvature, Fig. 5 (not shown). As the top sheet is moved forwardly for separation by rollers 351, Fig. 1, as described below, its side edges ride up the edges 461, until they snap-over and rest on the top of the cap. The remaining sheets of the pile are retained by the ledges 457. Each angle part 451 has attached thereto a member 465, Fig. 3, with a looped part 467 for sliding engagement with a transverse rod 473, Fig. 1, and with legs 469, Fig. 3, forming with the angle part 453 grooves engaged by the side wall of the pile table so that adjustment of the side wall according to the pile width also adjusts the comer stop. The pile table is raised automatically to keep the top of the pile at a fixed level and the stops can be adjusted to correspond with that level by vertical movement of the bar 473 effected by means of a handoperated eccentric 483, Fig. 1. The separator rollers 351 are driven intermittently in one direction through a one-way clutch operated by a rack-and-pinion 359.
