Abstract: 1,132,271. Internal resistance heating. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). 31 Jan., 1966 [8 Feb., 1965], No. 4236/66. Heading H5H. In a method of melting uranium and plutonium dioxide powders in a crucible a current path is provided through the powder of greater conductivity than that of the powder and heating current is first passed through the path to heat the powder surrounding the path and then heating current is passed through the heated powder. The melting apparatus comprises a water-cooled Cu crucible 2 having a graphite lining 3 and closed at the top by a vacuumtight housing 1. A graphite electrode 5 is mounted on a water-cooled Cu tube 4 slidable in the housing. A column 6 forming the path is placed between electrode 5 and the bottom of the crucible which is filled with powder 7 to be melted. The column may comprise compressed powder bodies, granulated residue of preceding melts or a graphite or tungsten rod, the rod being withdrawn after initial heating. A.C. or D.C. may be used and heating may be in a hydrogen atmosphere to produce a stoichiometric melt.

IPC: B21D53/04
Filed: 1966-02-01
Abstract: 1,174,233. Making heat exchangers; corrugating; bending; rolling. REDMAN HEENAN INTERNATIONAL Ltd. 15 Feb., 1967 [1 Feb., 1966], No. 4420/66. Headings B3A, B3E and B3M. A process for providing stretched forms continually along the length of a metal strip comprises continuously passing in tension the strip between first and second tensioning roller sets to continuously stress the strip at a value below the yield point and, progressively rotatably closing rotating mating male and female die members spaced apart a predetermined distance from one another in excess of the thickness of the metal strip and located between the tensioning roller sets, the male and female die members stretching said forms along the length of the strip. Strip 14 from a coil 16 passes between rollers 23, 24 of a first tensioning set 11, which serve to form longitudinal side channels 32, 33, then between rollers 18, 19 which form corrugations 34 in the strip between the side channels. The strip then passes between rollers 27, 28 of a second tensioning set 12 which serve to tension the strip below its yield point, between the sets 11 and 12, the rollers 18, 19 being so spaced and formed as to stretch form the strip over the ribs 40 of the roller 19 first between the set 11 and the rib 40, then between the set 12 and the rib 40. Two pieces of formed strip are secured together at 35, Fig. 2, to form a heat exchanger. Instead of corrugations separate dish forms may be produced in the strip.

A laminated web which may be slit to form continuous filament metallized thread is produced by coating one surface of a base web of flexible thermoplastic material, for example, polymerized ethylene glycol terephthalate, with a metal deposit, for example, by vacuum coating, coating one surface of a carrier web with a flexible synthetic resin film which may later be released therefrom, adhesively combining the metal-coated web and the synthetic resin coated carrier to joint the synthetic resin film to the metal coating, and stripping off the carrier. The synthetic resin coated carrier may be applied to both surfaces of the metalcoated base web. The adhesive layers may be pigmented, and the synthetic resin layer clear, to achieve a colour effect; or the synthetic resin layer may be pigmented. The base web may be of regenerated cellulose, cellulose acetate, triacetate, or acetate butyrate, or " Mylar " (Registered Trade Mark). The metal layer may be of gold, silver, aluminium, magnesium, titanium, or nickel. The flexible synthetic resin film may be of acrylic material, polyviny lchloride, or polyester, and cooled on to the carrier web by evaporation from solution.

Title: Improvements in and relating to the construction of concrete houses and like structures
IPC: E04G11/10
Filed: 1925-02-19
Abstract: 253,962. Bloomfield, H. Feb. 19, 1925. Moulding walls in situ.-Relates to shuttering for casting concrete walls of houses &c. in situ, the shutters being of the kind consisting; of rectangular frames adapted to be detachably secured tc one another and supporting sheets of metal or other suitable material. According to the invention, the sheets are so arranged upon the frames that at least one edge of each sheet overlaps its frame, while the parallel edge opposite, thereto lies within the limits of the frame. This facilitates the correct positioning of the shutters when placed together. Cavities are formed in the walls by using cores having removable filling- pieces, the outer shells of the cores being left permanently in position. Fig. 6 shows one of the shutters, which consists of an angle-iron framework 2 carrying a metal &c. sheet 1 arranged with overlapping edges b, c. The overlaps of adjacent shutters engage behind the projecting edges a, d of the frame. The shuttering is held together, as shown in Fig. 1, by nuts and bolts 3, wedges 4 being driven if necessary between the bolts and the flanges of the angle-irons. Gusset straps (not shown) hold the corners of the inner shutters in position. Cores for forming vertical cavities in the walls when the concrete is poured in between the shutters are shown in Fig. 2. Each core consists of a steel sheet facing 8 on a framework built up of wooden pieces 9, 9<a> -- 9<c>, and interconnected metal bars 9<d>. The parts of the framework are dislodged and removed when the casting of a tier of the wall has been completed, leaving the metal sheets 8 embedded. The cores can be suspended, during the casting, from transverse members consisting of two-part blocks 10 of wood or cement &c., Fig. 1; these surround the bolts 11 which space opposing pairs of shutters apart, and which are subsequently removed. Floor beams or joists may be supported in boxes 12, Fig. 8, cast into the inner walls, a horizontal metal bearing-plate 13 extending across the wall cavity being provided beneath each box and the space between the parts 12, 13 being filled up with concrete &c. Chimneys are constructed by casting earthenware pipes in the concrete breasts. Reference has been directed by the Comptroller to Specification 143,694.

[Also in Group XII] A method of surface blowing molten metals comprises passing a main stream of gas through a nozzle and passing secondary streams of gas into the main stream so that the main jet diverges. As shown, the gas, e.g. oxygen, may be passed through a nozzle 5 which is arranged spaced from and centrally of a water-cooled double-walled tube 1. Another gas, or, if desired, the same gas, at the same, a higher or a lower pressure, may be passed through the space between the nozzle and the tube and into the main stream through nozzles 6 the axes of which may be directed downstream and towards the axis of the main jet or may be arranged angularly thereto to produce a spin. Variation in pressure in the secondary gas stream produces variation in the amount of divergence in the main jet. The main gas stream may contain finely divided fluxes in suspension. Specifications 844,987 and 845,393 are referred to.
