Title: Substance exchange columns
IPC: B01D3/28
Filed: 1962-03-12
Abstract: <PICT:1005586/C1/1> <PICT:1005586/C1/2> <PICT:1005586/C1/3> <PICT:1005586/C1/4> <PICT:1005586/C1/5> <PICT:1005586/C1/6> Upright substance exchange columns horizontally divided into filled sections separated by unfilled mixing sections, through which a liquid and a gas flow in counter-current, are characterized by the presence of and inclined guide element above each filled section, whereby a lateral flow component is imparted to the rising gas.  Each "filled section" may be (a) a group of parallel ducts filled with filler bodies, (b) a group of parallel ducts of smaller diameter affording a large surface area, (film column), (c) a section containing statistically distributed filler bodies or (d) a section filled with layers of gratings. The columns may be applied to enrichment of isotopes, e.g. separation of deuterium and hydrogen, using a chemical exchange reaction. Fig. 2 illustrates a rectification column in which the exchange sections 11, 12, 13 are vertically sub - divided into parallel ducts 11a, 11b, 11c &c., each of which has a grating 18 having inclined guide elements 17 imparting lateral movement to the vapours rising out of the packing.  A grating of this kind, suitable for use where the individual ducts adjoin in honeycomb fashion (Fig. 3, not shown) is illustrated in Fig. 3b, and Fig. 3f shows in plan a grating having guide elements 20 (see also Fig. 2) for use at the bottom of the individual ducts.  It is stated that liquid may be conducted through the mixing chamber from the ducts to the corresponding underlying ducts by means of small tubes connected centrally to the guide elements.  Fig. 3c shows a quadrant of a grating for use at the top of a filled section made up of a plurality of square grating elements analogous to the grating in Fig. 3b and illustrates one way in which the rising vapours may be given rotary motion.  Vapour is discharged through pipe 21 to condenser 22 from which part of the condensate is returned to a collecting chamber 26 and distributed as reflux liquid through capilliaries 27a, 27b and 27c while part is withdrawn as product through valve 23. Line 24 is a connecting pipe for a pressure-adjusting system.  The mixture to be separated is admitted through valved line 19: if the mixture is a liquid, a system is provided to distribute it to the individual ducts of the bottom exchange section.  In Fig. 4 a section of a column is shown in which the exchange sections are not subdivided into separate columns but made up of a series of grids superposed in staggered relationship 30 and having a single deflecting grating 32 with guide elements 31.  The lower grating 33 is constructed as shown in Fig. 4b.  Fig. 5 (not shown) has similar upper and lower gratings but is packed with graduated particles in place of the grids.

Title: Boron concentration measuring device
IPC: G01N23/09
Filed: 1975-03-07
Abstract: 1478271 Measuring boron concentration COMMISSARIAT A L'ENERGIE ATOMIQUE 7 March 1975 [7 March 1974] 9617/75 Heading G1A The concentration of boron in the light water of the primary cooling circuit of a light water nuclear reactor is measured by sensing thermal neutrons scattered or reflected to a detector after emission from a high energy neutron isotopic source, the source and detector being mounted close to one another and being surrounded by a neutron-reflecting medium, which may or may not be contained in a separate vessel, so that the detector is positioned so as to receive the maximum reflected thermal neutron flux. As boron concentration increases, more neutrons are absorbed to create lithium in the B (n, α) Li reaction and the detector output decreases. To compensate for 7-radiation produced and detected by the thermal neutron detector, a gamma detector is also provided and the neutron count corrected. A typical gating circuit for such correction is given in Fig. 4 (not shown). Alternatively, a non gamma sensitive detector such as a fission chamber, may be used. In one embodiment, Fig. 3, the source 6, e.g. Am-Be, and neutron detector D a deposited-boron type or fission chamber, are mounted adjacent one another inside a cylindrical chamber Ea through which the boron-containing light water coolant flows via inlet 7 and outlet 12. A Geyer-Muller detector 8 is used for gamma ray detection. A hydrogenated medium e.g. pure water, or graphite contained in outer vessel Eb, slows down high energy neutrons from source 6 and scatters them back to the detector D. In an alternative (not shown), a spherical chamber E A  is used. The source and detector may, in another arrangement, Fig. 6 (not shown), be within the reflector medium in a vessel which partially encloses a pipe, through which the boroncontaining cooling water to be tested, flows. Temperature control of the apparatus may be provided. The measurement signal may be used for moderation control purposes.

Abstract: 436,082. Rack - and - pinion gearing. STAVERS, W. M., 54, St. John Street, London. March 28, 1934, No. 9697. [Class 80 (i)] The rack A has one or more teeth omitted, so that the drive from the pinion D ceases when the rack has reached a certain position. Reversal is obtained by replacing the first omitted tooth by a pivoted pawl E. The rack may take the form of a circular external or internal gear, or a non-circular gear may be employed. The lift of the pawl may be checked by adjustable stops on the framework, so that the pawl behaves like a solid tooth. In a vertical form for petrol pumps, the pawls are urged to operative position by springs. The rack may be connected to a driven ram through springs such as G<1>. The invention is applicable to the piston of a filling machine for sausages &c., where pasty material is forced by a piston through a nozzle into a tube of skin or metal, or into an open vessel, mould or shaping device. It is also applicable to buoys, where a light or sound signal is actuated by the rise and fall of the waves, and to submarine mines. Reference has been directed by the Comptroller to Specifications 210,240, [Class 80 (i)], and 359,699.
