Filed: 1942-10-14
Abstract: 557,656. Drilling-jigs &c. TILLETT, S. H. Oct. 14, 1942, No. 14403. [Class 83 (iii)] A bench jig for drilling, tapping, and like operations particularly for round section work has a locating block for the work adjustable transversely in the jig frame while the guidebush for the drill &c. is adjustable longitudinally in said frame. In one form the V-block for locating the work is of sectional construction and comprises a lower section 7 which may be used alone for large work-pieces, Fig. 3, and which for smaller work-pieces may carry a second V- block 9, Fig. 9, which has shoulders 14 resting on the lower block and is located by projections engaging notches 19 in the upper block. Alternatively the sections may be secured together by screws. The locating-block is adjusted along guide rails 20, 21 by screws 26, 27 and clamped by screws 31, 32. Interchangeable tool-locating bushes 40 are mounted. in a sleeve 41 in a bridgemember 39 which is adjusted by hand along a pair of fine-pitch screws 46, 47 passing through clearance holes in the bridge and is locked in position by nuts 50, 51, and screws 52, 53. A second bridge 62 adjustable along the frame carries clamping-screw 63 for securing the work. If necessary more than one clamping- bridge may be provided. When mounted in the jig, the work engages a fixed stop 64 secured by screws to the lower work-locating block. In some oases an adjustable stop 67 is employed. The horizontal limb of this member slides in a longitudinal groove in the lower surface of the frame and is secured in adjusted position by screws 70. By using this stop the range of longitudinal adjustment of the jig is increased. In a modification, the work-locating block is guided in its transverse movements by shoes carried respectively on the clamping screws 31, 32. To facilitate the adjustment of the bridge member the upper surface of one of the sides 5, 6 may have graduations coacting with a reference mark on the bridge. In another modification, the bridge 39 is adjusted by a screw passing through a tapped hole in the bridge. In a further modification, the tool-locating guide is adjustable both longitudinally and transversely of the jig. In this case the guide bush is mounted in a block 85, Fig. 14, which is movable along the bridge member in guides 88 by a screw 89 carried in lugs 91, 92. For work of square or other non-circular section the work block may be fitted with vice-like jaws for holding the work.

Patent GB-906618-A (GB)
Title: Improvements in or relating to uranium recovery processes
Inventor: MOLYNEUX JOHN
IPC: C22B60/02
Filed: 1960-04-26
Abstract: Uranium is recovered from alloys with zirconium, i.e. scrap from fabricating nuclear fuel elements or irradiated fuel elements, by dissolution in HF containing KF, whereby essentially all the U is obtained as a precipitate of complex fluoride and can thus be filtered off from the zirconium remaining in solution.  The uranium may be enriched in respect of U 235 isotope and may comprise 1-50% by weight of the alloy, which can include minor amounts of tin, iron, nickel and chromium as well as fission products, if the alloy has been subjected to neutron irradiation.  Fission products named are rare earth isotopes, niobium 95, strontium 89, caesium 137, ruthenium 103 and plutonium.  The usual alloy contains 5% U.  The preferred leach liquor for treating a 5% U containing alloy requires a fluoride concentration of 12 g equivalents per litre, of which 0,125 g equivalents are derived from the KF, for 2 g atoms of zirconium. Thus in Example (1) a zirconium alloy containing 5% U as well as 1,5% Sn, 0,1% Fe, 0,1% Ni, 0,5% Cr was treated in a polythene reactor fitted with a polythene condenser with a KF/HF leaching solution while maintaining a temperature less than 80 DEG C. by external cooling. After the alloy had dissolved, the contents of the reactor were allowed to cool to room temperature, the precipitated potassium fluoranate was filtered off and washed with 0,01 M aqueous KF, thus recovering 99,95% of the U originally present.  Other examples refer to larger scale operation in hydrofluoric acid resisting apparatus and recovery of U from an irradiated fuel element; the precipitated uranium complex fluoride may contain some fission products; separation of the uranium from the fission products may be effected by reacting the precipitate with a mixture of HNO3, Al(NO3)3 and KCrO4 to dissolve the complex and solvent extracting the uranium from the solution produced.

Title: Improvements relating to roofing
IPC: E04D3/32
Filed: 1936-05-25
Abstract: 472,926. Roofing; tiles. TURNER & NEWALL, Ltd., and ASHMAN, H. W. [Soc. Anon. Ciments Portland Artificiels Belges d'Harmignies, (partly).] May 25, 1936, No. 14783. [Classes 20 (iv) and 87 (i)] Relates to roofing comprising a series of courses of tiles which are of the kind described in Specification 416,840* and consist of a corrugated part and a flat part that is nearly as wide as the corrugated part, the corrugated part of one tile overlapping the flat part of the next tile so that a continuous double covering is provided in the roof. According to the invention, each complete tile is formed with the crest of the corrugation nearest the flat part lower than the crests of the remaining corrugations by an amount equal to the thickness of the tile, and the underside of the flat part is lower than the plane containing the lowest parts of the corrugated part by an amount which may be equal to, or double, the thickness of the tile. The tile shown in Fig. 2, comprises a flat part 12, and three corrugations 14, 15, 16 with intervening flat parts 17, 18, and this tile is also provided with a cornermitre 19 and a joggle-mitre 20. The roof shown in Figs. 1 and 2 is formed by first laying, in overlapping courses, three members X, Y, Z, comprising only the flat parts 12 of the tiles, and on these members are then placed, in overlapping courses, three tiles A, B, C, followed by three further tiles D, E, F, the end corrugation 14 of each of which overlaps the corrugation 16 of the adjacent tile A, B, C. The tiles D, E have corner-mitres 19 to fit jogglemitres 20 of the tiles B, C respectively. The last tiles G, H, J, comprise only corrugated portions, the tiles G, H having corner-mitres 19 to fit joggle-mitres 20 of the tiles E, F respectively. There is no direct contact between the corrugated part of one tile and the flat part 12 of another tile except where successive courses overlap. A modified form of tile has a strip of the flat part 12 cut away near the lower edge, as shown in Fig. 6, so that the flat part is shorter than the corrugated part, and the junction of the two parts is mitred as shown at 21. In forming a roof to include such tiles, the flat parts which are first laid do not overlap, and, owing to the modified shape of the tiles, overlapping tiles are in contact over their whole width. The corrugated parts of the tiles may be of sinusoidal form, without any intervening flat portions.

Abstract: 768,937. Automatic circuit-breakers. GENERAL ELECTRIC CO. May 23, 1955 [May 25, 1954], No. 14833/55. Class 38(5) An electromagnetic tripping device responsive to the current flowing through a conductive stud 15 has a U-shaped core 16 with its legs straddling a transverse intermediate portion 23 of the stud, this portion interconnecting other stud portions 21, 22 extending longitudinally parallel to the axis of the stud. When moderate overloads occur, an armature 31 is attracted to the core 16 against the bias of a spring 56 and turns a lever 12 to produce tripping of a circuit breaker indicated at 10, an inverse time delay being provided by a dash pot 40. Within an intermediate range of overloads, tripping is produced by a second armature 32 which is attracted by the core against the bias of a spring 43. In this case an inverse time delay is provided by an escapement mechanism 37. Under heavy overload conditions, the force acting on the armature is sufficient to overcome the bias of a spring 39 which normally maintains a lever 54 against a stop 55 on a lever 51. Thus with currents above the intermediate range, substantially instantaneous tripping occurs. As the armature 31 and levers 53, 54 can move against the bias of the spring 39 without turning the lever 51 coupled to the dashpot 40.
