Title: Improvements in and relating to a process for radiography and a material for carrying out the said process
IPC: G03C1/035
Filed: 1958-12-19
Abstract: 907,023. Radiographic films. CHASSENDEBAROZ, N. J. M. P. F. Dec. 19, 1958 [Dec. 19, 1957; Aug. 13, 1958], No. 41077/58. Drawings to Specification. Classes 98 (1) and 98 (2). A photographic film for radiographic work is coated with an emulsion containing silver chloride, the thickness being less than 50 microns (preferably 10-15 microns), and the silver content being 100-200 mg/sq. dm. This corresponds to a quantity of silver several times as much as is normally used in known silver chloride emulsions. An example is given of the preparation of a suitable emulsion. The use of such an emulsion gives a greater degree of difference between the photographic effect of relatively low-energy X-rays and relatively high-energy γ-rays than the use of silver bromide emulsions. Thus in cases where it is desired to photograph the effect of the X-rays in a beam, the effect of γ-rays unavoidably present in the same radiation beam not being required and tending to, fog the picture, the emulsion according to the invention gives increased contrast.

Title: Improvements in or relating to nuclear reactors
Inventor: GRATTON CHARLES PETER
IPC: G21C3/326
Filed: 1963-10-21
Abstract: 1,029,485. Reactors. SOC. ANGLO. BELGE VULCAIN. Oct. 20, 1964 [Oct. 21, 1963], No. 41558/63. Heading G6C. A nuclear reactor utilizing a combined liquid moderator and coolant has a core containing a symmetrical array of externally similar components, spaced apart to define liquid passages between them; most of the components are fuel bearing, but the remainder are empty of fuel, and include provision for filling their interiors with the liquid moderator. The fuel elements and dummies are of the elongate rod type and are made up into hexagonal section fuel assemblies each containing 37 components. The core is built up by close packing the hexagonal assemblies, a few of which are replaced by similar cross-section control rods. The object of the invention is to enable core layout details to be left flexible to as late a point as possible in the reactor development, thus enabling a fuel layout to be used of very nearly constant neutron flux. By using mixtures of fuel elements and dummies in each fuel assembly, flux is levelled by a flexible system of replacing fuel by moderator.

Filed: 1964-10-16
Abstract: 1,082,715. Hydraulic jacks. TECALEMIT (ENGINEERING) Ltd. Oct. 16, 1964 [Oct. 16, 1963], No. 42300/64. Heading B8J. A security device for a lift (not shown) mounted on a piston 3 sliding in a guide 2 in a cylinder 1 of a carrier jack locks the piston 3 by the wedging of rollers 7 between the piston 3 and the frusto-conical bore 10 of a locking ring 6. The action of the device is controlled by a control jack 9 connected to the control member of the carrier jack. When fluid pressure is applied to the cylinder of the control jack 9 an unlocking ring 8 with a rim 19 pivots at 17 and lifts the rollers 7 away from contact with the piston 3 so that the piston 3 is free to move. So that a slight leak in the carrier jack and consequent descent does not impair the operation of the control jack 9 the locking ring 6 is carried by springs 15 sufficient to carry the weight of the ring 6 so that although the rollers are in jamming position the jamming effect is less than the force of the springs 15. In an oleo-pneumatic system a small aperture 28 delays retraction of the control jack 9 when the look is applied to allow for the delay relatively to the operation of the control member. In an hydraulic system immediate purging of the control jack 9 is provided. The rollers 7 are solids of revolution the ends of each of which are convexly radiused to match the frustoconical bore 10, while the middle part is concavely radiused to match the piston 3. The sum of the lengths of the convex parts is equal to the length of the concave part of the roller 7. When applied to a non-vertical jack the rollers 7 are retained in a cage permanently urged by resilient means to bring the rollers 7 into contact with the piston 3 and the frusto-conical bore 10. The control jack 9 in such a case is arranged to overcome the resilient means to unlock the device.
