Title: Method for the electronic regulation of a plutonium extraction battery
Inventor: DEGRYSE MICHEL
IPC: G21F9/12
Filed: 1966-06-28
Abstract: 1,111,959. Processing spent nuclear fuel. COMMISSARIAT A L'ENERGIE ATOMIQUE. 28 June, 1966 [29 June, 1965], No. 28992/66. Heading G6R. [Also in Division G3] In the separation of uranium and plutonium from fission products by countercurrent extraction of an aqueous solution with a solvent, for example tributyl phosphate, the process is regulated electronically by measuring the plutonium retention in intermediate extraction stages by means of a neutron detector in each stage, integrating the impulses received from the detectors to provide a voltage which drives a motor associated with the feeding means for one of the liquid phases, so as to vary the ratio of the solvent flow rate to the aqueous solution flow rate. The neutron detectors may comprise cylindrical copper cathodes and coaxial anodes and may be filled with BF 3  enriched with B10. An alarm is provided to warn of excessive plutonium leakage.

Patent GB-690478-A (GB)
Title: Improvements in or relating to electrical resistors
IPC: H01C7/00
Filed: 1948-11-12
Abstract: An electric resistance is made by applying a recurring continuous fine line fine network pattern of substantially uniform thickness to the surface of an organic insulating material, the pattern consisting of a finely divided conductive material, a permanent insulating binder and a solvent, therefor, heat being finally applied to at least the coated portions of the insulating material.  In an alternative method the whole of the insulating surface is coated with the composition, a relief printing plate carrying the pattern of a fine line fine network and having heated contact areas is applied to the coating, and the unchanged coating is removed from the areas to which heat has not been applied.  In either of the above methods pressure may be applied during the heating operation.  A finely divided form of carbon, powdered metal or metal oxide is preferably used as the electrical conductor.  The binder may consist of a phenol aldehyde, urea aldehyde or melamine aldehyde condensation product, an alkyd resin or a styrene copolymer.  The pattern may be applied by any known printing process.  According to one example, a grid having 50 lines per inch is printed on a polystyrene film using an ink containing graphite, shellac, iso-propyl alcohol and linseed oil. The film is then heated to evaporate the alcohol and dry the sheet. In another method a sheet of aniline-formaldehyde paper-filled material is spread wth a conductive paste containing a phenol formaldehyde condensation product, carbon black and a solvent, and is allowed to dry.  A heated die showing a positive grid system containing 20 lines to the inch is placed on the sheet and pressure applied.  The sheet is then washed with a solvent to remove all parts of the coating containing uncured resin.  A further method comprises applying a slurry containing 60 per cent ferrum radactum powder in a lithographic varnish to a laminated phenol formaldehyde sheet. After pressing at 120 DEG C and 300 lb./sq. inch with a die showing a positive grid system the plate is washed in trichlorethylene to remove the unchanged parts of the coating.  Specification 690,486 is referred to.

Screw-and-nut mechanism. - In means for lifting, lowering, hauling, loading, and unloading and for power and motion transmission generally, applicable to lift-cages, vehicles, boats, builders' cradles, &c., a wire or like rope or cable has its external strands resembling screw - threads so that it may form one member of a screw-andnut mechanism. In the form shown applied to a builders' cradle, ropes n, the upper ends o of which are suitably anchored and the lower ends secured together to prevent torsion, pass through sleeves c carrying, secured thereto, nuts l and, loosely, rather larger supporting-nuts m. The sleeves carry sprocket-wheels d, which are connected by a chain e rotated by an endless chain k and gearing j, i, h, f. The sleeves c are carried in bearings r in the cradle, so that when the sleeves are rotated, the cradle is adjusted. A similar mechanism may be used for traversing the cradle. The sleeves, nuts, and bearings may be formed in two or more hinged or separate sections, secured in place by padlocks, clips, clamps, &c. The rope may form the driving-member of the gear, for which purpose it is rotated or moved axially.
