Abstract: 1,239,013. Purifying by recrystallization. HOPKIN & WILLIAMS Ltd. 20 Sept., 1968 [27 Sept., 1967], No. 43941/67. Headings B1G and B1S. [Also in Divisions C1 and C2] A substantially vertical column of an impure, finely comminuted and evenly packed substance is purified by adding at the top of the column a liquid which is a solvent for the substance and at least some of the impurities at a rate such that at any instant the quantity of solvent in the column is sufficient to dissolve only a part of the substance, so that a solvent vapour phase exists in dynamic equilibrium with the solvent, and removing from the lower end of the column a saturated solution of the substance and impurities. The solvent may be added continuously or in discrete amounts; successive such amounts may be of different solvents. The process may be conducted at an elevated temperature approaching the m.p.t. of the substance. Remaining solvent may be removed by suction, pressure or a non-solvent liquid. In examples the following are purified (solvents in brackets); dipyridyl, 1-nitronaphthalene, phenol, 1-naphthyl acetate and 2, 4-dichloraniline (acetone); 1, 10-phenanthroline hydrate (industrial methanol + acetone); Na heptoate, urea and manganese acetate (water); p-phenylene diamine (pyridine/hydrazine hydrate followed by toluene/hydrazine hydrate); and naphthol (toluene). Sodium nitrate (water/ acetone); barium acetate (water/acetic acid). Yields may exceed 85-90% using very small relative amounts of solvent.

Abstract: 1,002,480. Valves. CONTROL MAATSCHAPPIJ EUROPA N.V. Aug. 6, 1963 [Aug. 10, 1962], No. 30932/63. Heading F2V. A gas safety valve has a tapered rotary cock 9 the operating knob 1 of which houses a spring-loaded push-button 2 having a shaft 3 that embodies a radial pin 5 which must be aligned with a slot 4a in the cock body, i.e. the cock must be in the closed position before the shaft can be depressed. The shaft 3 includes a delay mechanism consisting of a dashpot 8a with a spring 8 which slowly extends the shaft 3 after it has been depressed, and collars 11, 12 between which is one bifurcated end of a lever 13 that contacts a pivoted and spring-loaded block 14 which in the position shown locks the cock 9 against rotation; the block 14 also actuates contacts 21 in a circuit to an ignition coil 22 which is disposed above a pilot burner 23. A thermo-couple 29 is positioned adjacent the latter. The other end of lever 13 which coacts with a toggle spring 13a, is coupled to a valve 17 in the gas supply, the valve 17 being connected to the thermo-couple 29. Operation of the safety valve is effected by firstly depressing the button 2 to release the block 14 whereby the cock may be rotated, when the pin 5 rides out of the slot 4a, to provide a gas flow via conduit 32 to the pilot burner 23, which is ignited by the coil 22. Gas also flows through a conduit 31 and a thennallyresponsive valve to the main burner 24. Shaft 3 slowly returns to the inoperative position wherein the block 14 abuts the cock 9 and the coil 22 is de-energized. Block 14 cannot lock the cock 9 until the latter is again turned to the closed position. Once the cock is closed it cannot be reopened without the delay imposed by the dashpot. The thermally-responsive valve consists of a room temperature sensing head 25 and bellows 26 controlling the moving closure member 27. The valve 17 is held open by an electromagnet 33 and is spring-closed when the pilot burner 23 is extinguished.

Abstract: 1,252,939. Pneumatic tyres. MICHELIN & CIE COMPAGNIE GENERALE DES ETABS: MICHELIN. 13 Nov., 1968 [13 Nov., 1967; 19 Sept., 1968], No. 53894/68. Heading B7C. A pneumatic tyre has a carcass comprising an even number of superposed parallel cord plies 10, 11, the cords of which make an angle of between 30 degrees and 70 degrees with the radial direction in the lower sidewall region 14, and an angle of less than 15 degrees in the upper sidewall region, thereby creating in this upper region a " zone " of maximum flexibility for the tyre. The cords make an angle of between 60 degrees and 80 degrees with the mid-circumferential plane of the tyre in the under-tread region, and may be made or cotton, rayon polyamide, polyester, glass or steel. The width of the flexible zone is normally between one quarter and one third the height of the carcass, but it can merely consist of the circumferential demarcation line between the differing cord angles of the tread and sidewall regions, while the length of cord in the flexible zone is between 1% and 12%, preferably 5%, of the total beadto-bead cord length. Local reinforcements may be incorporated into the tyre, in the form of a ply 30 with folded-over portions 32, 32<SP>1</SP>, the fold portions of which coincide with the junction of the tread region and the flexible zone, and the cords of which lie parallel to the cords of the underlying carcass plies. Another reinforcing ply 40 is shown, with its fold portion coinciding with the junction of the lower sidewall and flexible regions. Method of manufacture.-A bias cut cord ply 72 is adhered to a drum, which may be the tyre building drum and which comprises three coaxial rotatable sleeves 70, 71, 72, the cords being inclined at an angle α to the drum's midcircumferential plane. Sleeves 71, 71<SP>1</SP> are then moved outward and simultaneously rotated in the directions shown by the arrows until the cord sections in the gap regions 73 are inclined at an angle α in the opposite sense to the original, (Fig. 9, not shown). A further ply 75 is then added, its bias angle being α, and sleeves 71, 71<SP>1</SP> are again rotated until the two cord sections in each gap 73 lie in or near an axial direction, thereby constituting the flexible zone of the completed tyre. In a similar method, the drum constitutes the tyre building drum and has four rotatable sleeves, there being two sleeves instead of one sleeve between the gaps 73, enabling the crossed cords of the crown region to be arranged at unequal, opposite angles to the tyre's mid-circumferential plane.

Heading G6C. In a gas-cooled fast reactor employing porous fuel in the form of coated fuel particles bonded together to form tubular fuel elements, the coolant gas flowing radially across the fuel between the inner and outer surfaces of the elements, means are provided to ensure that the gas pressure drop between the inner and outer surfaces is uniform along the length of the elements. One example of fuel element 1, Figs. 2, 3, which, in use, is mounted vertically in spaced relationship with other similar elements to form the reactor core, comprises a stack of annular cartridges 6a of porous fuel arranged between lower and upper end fittings 3, 5, respectively. The outer surfaces of the cartridges 6a are bounded by overlapping sleeves 7 of stainless steel mesh and the inner surfaces are bounded by overlapping tubes 8a of ceramic having gas ports 11 leading to annular grooves 10. The coolant gas enters the core through holes in the bottom grid 18 in which the fuel elements 1 are held by latches 17, the gas flowing through the spaces between the elements and entering the space 2 within the elements by flowing radially inwards through the fuel cartridges 6a, the heated gas leaving through the divergent passages 4 in the end fittings 5. The upper ends of the elements 1 are sealed by rings 20 in an upper grid (not shown). Graphite bushes 15, 19 serve as neutron reflectors. The gas pressure drop in the radial direction is made uniform along the length of the fuel element by gradually increasing the diameter of the space 2 in the direction from the upstream to the downstream end. In another embodiment, Fig. 5, the tubular fuel elements 31 are provided at their downstream ends 36 with conical baffles 38 which cause the coolant to take a longer path in passing through the porous fuel and thus cause an increase in gas pressure drop in this region. In another embodiment, Fig. 6, the coolant gas flows through the inlet spaces 43 between the tubular fuel elements 41 in a direction opposite to that in which it leaves through the spaces 44 in the fuel elements, whereby the gas pressure drop is kept uniform along the length of the elements. In a further embodiment, Fig. 7, the fuel elements 51a, 51b, are in the form of truncated hollow cones, the coolant gas entering through holes 55 and leaving through holes 58. The gas pressure drop is determined by the slope of the cones and also by the thickness of the cone walls which increases upwardly from the cone base.
