Title: Improvements in or relating to methods of forming nuclear fuel bodies
Inventor: REDDING GEOFFREY BRIAN
IPC: G21C3/64
Filed: 1964-10-30
Abstract: Particles are coated by tumbling the particles in a drum into which powder grains which have been previously treated with a binder are introduced, and softening the binder by contacting the grains with a solvent for the binder as the grains enter the drum. The coated particles may be formed into compacts by pressing and heating to set the binder.  The particles may be nuclear fuel particles e.g. carbides of nuclear fuel metals, which may be precoated with a fission product retaining layer of pyrolytic carbon, the powder grains being a carbonaceous material such as graphite.  In the embodiment of the invention, a batch of nuclear fuel particles pre-coated with pyrolytic carbon was placed in a rotary drum.  A supply of graphitised grains of calcined petroleum coke treated with a phenol-formaldehyde resin and a supply of solvent methylated spirit were mounted above the drum, suitable feed pipes being arranged to communicate the supply of grains and solvent with the interior of the drum so that the grain and a mist of the solvent contacted one another.  The coated particles were then heated in a furnace in vacuum, divided into batches which were formed into compacts using an electrically heated die.

Abstract: 1286636 Measuring charge density A O SMITH CORP 12 Sept 1969 [20 Dec 1968] 45200/69 Heading G1U In apparatus for measuring the charge density in a liquid, e.g. a hydrocarbon, flowing in a pipeline 10, Fig. 2, a fixed pick-up electrode 31, and a rotatable screen electrode 30, shaped as shown in Fig. 4, are mounted inside a wire-mesh cylinder 43a which protrudes into the path of the liquid but presents only a small obstruction to it. The rotatable screen electrode is mounted on a shaft 29 terminaling in a flange 32, which, when the apparatus is not in use, is covered by a cap 18. In use the cap 18 is removed and an explosion proof motor drive unit Fig. 5 (not shown) is clamped in its place so as to rotate the shaft 29 and the screen electrode 30 mounted on it. Electrically the system operates as follows. The wire mesh cylinder 43a, and the screen electrode 30 are both earthed thereby defining a volume of liquid within the cylinder and within which the total charge is measured. The pick-up electrode 31 is mounted on insulating spacers 43 and is connected to an electrometer. Assuming that the liquid in the pipe line 10 is positively charged, when the screen electrode, which is earthed, exposes the pick-up electrode 31 it will become negatively charged, by electrostatic induction, to a level determined by the total positive charge carried by the liquid within the wire mesh cylinder, and this charge is indicated on the electrometer. The motor drive unit Fig. 5, (not shown) also includes a magnetically actuated reed switch assembly 97, 101, 100, which is arranged to earth the pick-up electrode 31 for the period that it is screened by the screen electrode the pick-up electrode is alternately exposed and screened twice, and when exposed the charge on it is indicated on the electrometer. Hence, either by appropriate calibration, or by using tables, the charge density within the fluid can be determined. Two such charge measuring arrangements could be mounted before and after a static charge reducer 4, Fig. 1, in or to measure its efficiency.

[Also in Division F1] A locking means for preventing axial movement between a compressor shaft 21 and a turbine shaft 22 which are splined together at 34, 35, comprises a sleeve 33 screwed to the end of the compressor shaft 21 and having splines 37 engaged in a groove 36 in the splines 35 of the shaft 22 so that the sleeve 33 may be rotated to align the splines 35, 37 and thus prevent axial movement of the sleeve 33 and shaft 21 relative to the shaft 22. When the splines 35, 37 are aligned a spring-pressed plunger 45 moves radially out to engage a hole 43 in a sleeve 40 splined to the shaft 22 and thus prevents further rotation of the sleeve 33. To release the coupling a rod 50 depresses the plunger 45 and permits rotation of the sleeve 33 to a position in which the splines 37 pass between the splines 35 so that the shaft 22 may be withdrawn axially. The relative axial positions of the shafts may be adjusted by screwing the sleeve 33 into or out of the shaft 21.

In an airborne pulse radar for terrain avoidance the aerial, relative to the aircraft, is movable in azimuth and fixed in angular elevation, the receiver affords in response to each emitted pulse a group of signals corresponding to the elevation of points of the terrain within a selected range at the corresponding azimuth position, the signal representing the highest elevation (height) of the terrain is extracted from that group, and one pair of co-ordinate deflection means of a display device is energized in response to the extracted signals the other pair of co-ordinate deflection means being energized in accordance with the azimuthal position of the aerial. The angular elevation of echoes is given by the ratio of difference, A, and sum, # signals-in a monopulse arrangement, Fig. -2 (not shown), a computer (22) affording signals representing the difference between the distance Fig. 1, h (not shown); of terrain at range R below the aircraft's (level) flight path and the distance h 0  of a " clearance plane " below the latter, in accordance with the expression: R(γ+K#/#) - h 0  where K is a constant and γ is the depression angle of the monopulse bore-sight axis. The computer output is fed to a capacitative peak detector (26) discharged by a pulse in each radar pulse repetition period, the output voltage from which is proportional to the highest terrain elevation and is fed to the vertical deflection circuits (28) of a direct-view storage tube (29) via an integrator (27) for reducing noise and spurious signals. The predetermined range gate (24) corresponding to range R is selectable. The horizontal deflection circuits (31) are fed from a resolver (32) coupled to the azimuth scan (e.g. 120 degrees) of the aerial. The display afforded, Fig. 3 (not shown), is a line 34 indicative of the height of the clearance plane; an electronic cursor (37) is imposed on the face of the display tube to show the position of the aircraft, together with electronic vertical (35) and horizontal (36) cross-hairs.

An epicyclic gear comprises stepped planets 12, 15 on an output carrier 14 meshing ring gears 17, 19, the former 17 of which is held by a one-way brake (18) against clockwise rotation (as seen from the right of Fig. 1) so that anticlockwise rotation of an input shaft 10 causes anticlockwise rotation of the output shaft at one ratio, whilst the latter 19 is held by a brake (31), Fig. 3 (not shown), against anticlockwise rotation when the input shaft rotates clockwise to provide clockwise rotation of the output shaft at another ratio. Clockwise rotation of the input shaft rotates clockwise a sun 20 which acts through a one-way clutch and slip coupling 22, 23 to rotate a hub 24 clockwise against the bias of a spring (26) and engage a pawl 31 carried by the hub with the-ring gear 19.
