Patent GB-205503-A (GB)
Title: Manufacture of mono-azo-dyestuffs
Filed: 1923-10-12
Abstract: Monoazo-dyes are prepared by coupling diazotized m-aminobenzaldehyde, or a substitution product thereof, with a pyrazolone, and, where the product is insoluble or only slightly soluble in water, in sulphonating the product; in place of a m-aminobenzaldehyde a substance yielding one may be used such as an oxime, hydrazone, or aldazine.  The products dye wool from an acid bath in even greenish-yellow shades fast to light, alkalies, and washing. According to examples (1) diazotized m-aminobenzaldehyde is coupled with 1-p-sulphophenyl-5-pyrazolone-3-carboxylic acid or 1-(41-sulpho-21-tolyl)-5-pyrazolone-3-carboxylic acid, (2) diazotized 2-chlor-5-aminobenzaldehyde is coupled with 1-p-sulphophenyl-5-pyrazolone-3-carboxylic acid, or with 1-phenyl-3-methyl-5-pyrazolone followed by sulphonation; the latter dyestuff is practically the same as that from 2-chlor-5-aminobenzaldehyde and 1-p-sulphophenyl-3-methyl-5-pyrazolone.  Other pyrazolones which may be used are halogen or oxy-derivatives, such as the 1-(21-chlor-51-sulphophenyl)- or 1-(51-sulpho-31-carboxy-21-oxy-phenyl) -3-methyl-5-pyrazolone. Specifications 5167/96 and 13744/96 are referred to.

Title: Dielectric heating apparatus
Inventor: GRINSTEAD LESLIE
IPC: B29C65/04
Filed: 1949-10-07
Abstract: 679,644. Dielectric heating; seaming plastics. COMMUNICATIONS PATENTS, Ltd. Jan. 8, 1951 [Oct. 7, 1949], No. 25835/49. Class 39(iii) Dielectric heating apparatus for a frequency of over 30 megacycles comprises two main electrodes between which heating takes place energized by a series-connected capacitor having electrodes of surface area greater than those of the heating electrodes, and the electrically common electrodes of this series arrangement are movable together with respect to the other electrodes. Thus in seaming plastics, energy is directly supplied to an electrode 4 with an upper face 5 corresponding in size to the strip weld desired and supported in insulation in a metal stand which carries also a flat metal plate 6 with its top surface in the same plane as the face 5. The electrode plate 6 is also directly energized, has a larger area than the face 5 and may be an earthly electrode. The opposing common electrode comprises a metal bar 8, which is mounted on a reciprocated insulation block 9, has a face corresponding with the face 5, and has a metal side extension plate 10 of large area spaced above the plate 6, so that when this electrode is lowered, the plastic is welded between the faces 5, 8, and the field induced between the plates 6, 10 is too weak to heat the plastic. The plate 8 may carry several extensions 10, each over a corresponding plate 6. Thus the upper movable auxiliary electrode may be a metal disc 15 mounted over a directly energized plug 11 mounted in insulation in an aperture 12 in a metal casing 13, the upper surface 14 of which also forms an energized electrode. The lower side of the disc 15 may have a projection above the plug 11. The member 13 may form the outer conductor of a coaxial cable with its central conductor connected to the plug 11, or it may form part of a casing accommodating electrical equipment. In Fig. 3, a directly energized electrode 16 is a flange at the end of a cylindrical tube 17 forming a shield for a central conductor 18 with a radial extension 19 at its upper end accommodated in a space formed by cutting away part of the tube 17. The area of the electrode 16 is much greater than that of the electrode 19. The upper auxiliary vertically movable electrode 20 has an area corresponding with that of the electrode 16 and an extension 21 corresponding with the electrode 19, whereby substances may be heated between the members 19, 21.

Filed: 1939-09-18
Abstract: 532,645. Uniting by fusion; supplying current to moving conductors. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 18, 1939, No. 26091. Convention date, Sept. 16, 1938. [Class 83 (iv)] [Also in Group XXXVI] In an arc welding-apparatus, welding current is supplied to the electrode by brushes supported by contact blocks which are pivoted in a frame, the brushes being biassed into frictional engagement with the electrode through through resilient means associated with one of the blocks and clamping. means associated with the resilient means and another of the blocks. The contact blocks 21 are pivoted at 22 in levers 15, 16, which are pivoted at 19 to a frame 11. Two or more sets of grooved brushes 14 are carried by cylindrical members 24 which are adjustable by screws 26 in recesses 25 in the blocks being held in correct angular position by screws 29 passing through split ends of the contact blocks or by a key and groove connection. Each lever consists of two spaced arms 17 connected by spacers 18 and to the spacers on the lever 16 is connected a pair of springs 40 passing through a block 43 having projections 44 slidable in slots 45 in a U-shaped clamp 42 which has curved arms 46 engaging the curved surface of a cylindrical latch member 41 eccentrically supported in the lever 15. The spring is tensioned and the brushes brought into engagement with the electrode 39 by a screw 47 'threaded into the clamp. Wear on the brushes or variation in the diameter of the electrode are automatically compensated for due to the tension of the springs. The pivoted arrangement of the levers and contact blocks allows the entire brush mechanism to move in order to compensate for bends or kinks in the electrode. The contact pressure may be varied to suit the diameter of electrode by adjustment of the screw 47 and block 49 may be mounted on the lever 16 to serve as a stop limiting the flexing of the springs as the screw 47 is tightened so as to shorten the effective length of the springs to vary their stiffness. The clamp may be quickly released to facilitate threading of the electrode through the mechanism by rotating the latch member 41 by a handle 50 about the eccentric pivot 51, the weight of the other end of the clamp causing it to pivot on the projections 44 and to slide down thereon. The contact blocks are connected by cables 38 to the lower of two terminals 34, which pass through insulating layers 32 screwed to the block 31 and are connected by a connector 36. The electrode passes through a nozzle 12 which is cooled by the circulation of water through a longitudinally partitioned tubular member 10 forming part of the frame.

Title: Nuclear reactor fuels

Filed: 1971-04-19
Abstract: 1324746 Fuel material; processing spent nuclear fuel LE CARBONE-LORRAINE 19 April 1971 [8 April 1970] 26392/71 Addition to 1230549 Headings G6C and G6R A fuel material comprises particles of a nuclear fuel, each of which particles is coated with pyrocarbon and either each particle or each group of particles is agglomerated with expanded graphite, the particles being uniformly distributed in spaced relationship in at least one layer within a flexible sheet of carbonaceous material, which sheet has been subjected to slight but sufficient compression to assume flexible sheet form. The carbonaceous material may include carbon or graphite fibres which are added to the expanded graphite to increase the suppleness of the resultant fuel material. The particles are applied to a sheet of expanded graphite by being disposed on a lattice with a mesh size slightly smaller than the particles, the expanded graphite being placed on the mesh which is then turned over and slightly compressed so that the particles adhere to the expanded graphite, after which the lattice is withdrawn. By covering the particles when on the lattice with a carbonizable or soluble adhesive film, the lattice may be laid over the expanded graphite. A second sheet of expanded graphite free of fuel particles is then placed over the particles on the first sheet and sufficient pressure applied to produce a compacted flexible laminate. Alternatively, a second spatially separated arrangement of fuel particles can be applied to the second sheet of expanded graphite and the process repeated to produce a laminate of a desired thickness, the final sheet of expanded graphite remaining free of fuel particles. The laminates are finally cut into tablets, each of which contains at least one fuel particle, and these may be packed into graphite containers to form nuclear fuel elements. After utilization in a nuclear reactor, the fuel material may be released from the fuel elements and, with the aid of an air selector crusher or similar apparatus, the fuel particles may be easily separated from the expanded graphite without the pyrocarbon coatings being subjected to any damage. The expanded graphite is reduced to a powder and kept in suspension by the speed of rotation of the blades of the apparatus, whilst the fuel particles fall to the base of the apparatus where an orifice permits them to be easily recovered.
