Title: Nuclear Fuel Elements.
Inventor: YATES JACK
IPC: G21C3/36
Filed: 1966-07-15
Abstract: 1,195,222. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 14 July, 1967 [15 July, 1966], No. 32022/66. Heading G6C. In the manufacture of a plate-type nuclear fuel assembly, the edges of fuel element plates 11 are located in slots 14 in comb-like members 13 disposed at intervals along the length of the edges and the slots 14 are then skewed about the edges so that the comb-like members 13 jam on the edges. As shown, the slots 14 in the member 13 are oblique to its length and the member 13 is urged along the plates 11 by means of a taper-ended drift 15. The plates 11 are disposed within a box 12. A like member 13 is simultaneously slid along the opposite edge of the plates 11. When the members 13 abut stops 16, a square-ended drift 17 is used to bring the members 13 square to the plates 11 and thus to skew the slots 14 relative to the edges to jam the slots on to the edges. When end member 13 is in position it is secured by depositing weld metal on to the member through holes 18 in the box 12. Alternatively, the slots in each support member are normal to longitudinal, a square-ended drift being used to initially position each support member and a taper-ended drift to skew each support member. In either case, an end comb having shallow tapered slots, the width decreasing with depth, is initially welded in place across one end of the box 12 and as the members 13 are driven into place, the plates 11 are forced into the tapered slots. Finally, the plates 11 are trapped by a second end comb which is welded in place across the other end of the box 12. With annular fuel plates, the comb-like members 13 are placed on the ends of the plates and then twisted. If the members are naturally fitted chordally they are twisted to follow a radius, whilst if they are naturally fitted radially they are twisted to follow a chord. If jigs are used, it is possible to form a box-type assembly between two side plates, the other two sides of the box being formed by fuel plates rather than as parts of a continuous shroud.

Abstract: 1281546 Trigger tube circuits DYNAMICS (BRISTOL) Ltd 25 June 1970 [25 June 1969] 32107/69 Heading H3P A cold cathode trigger tube 8 forming part of a delay circuit is turned off when a preceding, similar, tube 5 is turned on. The circuit is described in logic terms, in which a " 0 " applied to the trigger of 5, which is energized from rectified but unsmoothed A.C., allows this tube to turn off, thereby causing the point 2 to become " 1 ". After a delay imposed by RC circuit 6, 7 the trigger of tube 8 also becomes " 1 ", turning it on to produce a " 0 " at 3. Tube 8 is energized from a smoothed source so it stays on until tube 5 is turned on by a " 1 " on its trigger. The resultant potential drop at 2 is reflected through capacitor 4, and is assisted by a capacitor 9, so that the anode potential of 8 is dropped low enough to turn it off.

Abstract: 1,243,971. Blocking. FUNDITOR Ltd. 11 Oct., 1968 [12 July, 1967], No. 32111/67. Heading B6J. [Also in Division B3] A method of impressing marks on a metal surface by means of a die includes interposing an aluminium foil between the surface and the die, and pressing the foil on to the surface by means of the die, using sufficient pressure to carry an area of foil into the surface and to cold weld part at least of the area into the surface. For marking by hand, the foil is placed over the work and a punch applied through the foil. A die may impress the work in an initial step, followed by a further step in which the foil is interposed between the die and the work. A curved or cylindrical die may be rolled across a flat surface; or a flat die may be used and the work rotated. The foil may have a lacquered or coloured anodized surface. Apparatus for making a twist drill 1 by the method may include a carriage for lowering the die (not shown) and traversing it across the drill to effect the marking operation. The foil is carried by two rolls one or both of which are driven to feed the foil. In the construction illustrated, Fig. 1, the drill is supported on rolls 2, 3 on a table which is raised by a pneumatic cylinder to apply the drill to the die. The foil 6 is fed from a roller 7 to a roller 8 by a pneumatic cylinder 30 which, through a rack-and-pinion 28 and a pawl-and ratchet, rotates the roller 8 in steps. A rubber pinch roller 25 holds the foil against roller 8, and the length of foil between the rollers is guided by rods 9, 10 on adjustable booms 11, 12. In operation, the die is passed across the drill from right to left and back again in a double pass for cutting the foil, forming indentations in the drill and cold-welding the foil in the indentations.

Title: Processes for separating solid hydrocarbons or solid complex compounds of hydrocarbons with urea or thiourea from mixtures thereof with oils or highly polar liquids
Filed: 1952-12-19
Abstract: Solid hydrocarbons or solid complex compounds, e.g hydrocarbons with urea or thiourea, are separated from a mixture thereof with a highly polar liquid by contacting with a carrier liquid, so that the angle between the direction of the interfacial tension of the two liquid phases and the surface of the solid substance under equilibrium conditions at a point where the three phases meet, as measured over the carrier liquid, is less than 90 degrees.  The highly polar liquid separates from the solid substance, or the solid substance enters the carrier liquid phase.  Highly polar liquids are those having a dielectric constant greater than 25, for example water or an aqueous liquid. The carrier liquid has a dielectric constant below 20; liquids specified are hydrocarbons such as propane, butane, pentane, hexane, heptane and benzene, and ketones such as methylethylketone. The process may be applied to the separation of the mixtures formed in processes described in Specifications 733,067 and 734,132.  In an example, a waxy distillate from crude oil was diluted at 70 DEG  C. with dichloroethane and the mixture cooled to 20 DEG  C.  The slurry obtained was emulsified with water containing sodium dodecylbenzene sulphonate and sodium hydroxide. The paraffin wax transferred to the water phase and the oil-dichlorethane phase was decanted therefrom. According to the present invention, the wax-water suspension was stirred with pentane saturated with paraffin wax as carrier liquid. The wax transferred to the carrier liquid and was separated from the pentane by skimming, decanting or filtering.  In another example, magnesium sulphate was used as demulsifier in the water phase containing the sulphonate and sodium hydroxide.

[Also in Division H2] The segments of a radial face commutator have a conductive material portion forming the brush engaging surface supported by a second material acting as a heat sink. The commutator is made by placing an annular copper disc 11 which is formed with a flange 14 at its inner periphery and equiangularly spaced U-shaped radial flanged recesses 15 at its outer periphery. An annular aluminium disc 16 having U-shaped slots for co-operating with flanges 15 is engaged with copper disc 11. The assembly is pressed to provide radial grooves 17 which have a depth greater than the thickness of the two discs and thereby provide ribs 18 on the exposed surface of copper disc 11. Lugs 19 are formed on the exposed surface of the aluminium disc and a synthetic resin support body is moulded on to the aluminium disc. The face of the copper disc is machined to remove ribs 18 and thereby separate the segments of the commutator. In a modification the aluminium disc is replaced by a plurality of pre-formed sintered iron segments which are brazed to the copper disc, Figs. 5 and 6 (not shown). When assembled in an electrical machine the connections to the winding are made at recesses 15.
