Title: Manufacture of electrical heating and conducting devices
IPC: F24D13/02
Filed: 1957-11-18
Abstract: 905,867. Electric heating resistances. EISLER, P. Nov. 17, 1958 [Nov. 18, 1957], No. 35912/57. Class 39 (3). [Also in Group XXII] Crimped metal foil 71 for heating, e.g., wallpaper, ceilings, floors, tapes or as radiating surfaces or for making dispensable food packages or food heaters is slit as in Fig. 1 along discontinuous cuts between one or more pairs of rollers 72, 73, the slits then being widened or expanded by the pull of other rollers 74. A bend-over guide 75 leads the foil previously stretched over the end of the lower roller 74 so that it issues with bent-over edge 76 which may be flattened out later or bent over double to strengthen the edge. In Fig. 17 an insulated film 82 is stuck to the foil by adhesive from a trough 83, the expanding in Fig. 17 being done between two endless bands of rubber &c., 77, 78. In Fig. 18 an upper roller 85 both slits and deforms the foil in co-operation with a resilient counter roller 86 and also presses one or more insulating films against the foil 87. The foil may also be bunched " up " in concertina fashion. In Fig. 4 the expanded metal foil 11 is fed along a mandrel and is bound at the same time by helical adhesive or stitched-on tape which is then slit by a cutter 35 to produce a flat stiffened sheet of foil. Expansion of the foil may alternatively be produced by squeezing the foil locally to obtain groups of " pimples " which may also vary the resistance locally. Specifications 900,515, 900,517 and 900,518 are referred to.

Title: Improvements in or relating to the recovery of plutonium from organic solvents
Inventor: JAMRACK WILLIAM DOUGLAS
IPC: C01G56/00
Filed: 1954-12-11
Abstract: 834,531. Recovery of plutonium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 6, 1956 [Dec. 11, 1954], No. 35916/54. Class 39(4). Plutonium is recovered from a solution of plutonium nitrate in an organic solvent by mixing the solution with aqueous oxalic acid solution so as to precipitate plutonium oxalate. The precipitate collects in the aqueous phase and may be removed by filtration, any plutonium remaining in solution being recovered by oxidation with nitric acid and extraction with the organic solvent. The presence of nitric acid in the aqueous phase reduces the solubility of plutonium oxalate. The solution treated may be the tributyl phosphate extract of an aqueous aluminium nitrate solution of calcium fluoride slag resulting from the reduction of plutonium tetrafluoride by calcium metal.

Patent GB-411939-A (GB)
Title: Improvements in or relating to the manufacture of boot and the like soles and heels
IPC: A43B13/04
Filed: 1932-12-21
Abstract: Soles for footwear are formed by impregnating and surrounding textile yarns with a rubber dispersion, e.g. rubber latex, preferably in the undepolymerised and unvulcanized state, by immersing the yarns in the dispersion, applying fluid pressure, and coagulating the dispersion after removal of the yarns, forming the impregnated yarns into the shape required, by cutting or moulding, and then vulcanizing.  The vulcanizing and subsidiary agents, such as accelerators, activators, fillers and anti-oxidants may be incorporated in the rubber textile mixture, and preservative reagents may be introduced into the textile material, if desired.  The textile yarns may be in the form of a felted fabric, the rubber dispersion binding them together. Alternatively, the textile yarns may be spun or partially spun into threads or cords which, before or after impregnation with the rubber dispersion, are laid or woven to form a fabric which is subsequently treated with a rubber dispersion.  Certain portions of the sole, e.g. the edges, may be increased in density or thickness by using additional amounts of felted fabric, impregnated thread or rubber. The interstices between the yarns or threads may be so arranged as to permit the passage of air without permitting water to pass.  The impregnated textile material may be made up in the form of sheets from which pieces of the desired shape may be cut, and two or more layers may be superposed if the thickness is insufficient, with or without a layer or layers of rubber between.  Specifications 272,187, [Class 70], and 344,414, [Group VIII], are referred to.

Title: Method and apparatus for performing a change in the direction of movement of a travelling paper web
IPC: D21G9/00
Filed: 1961-10-16
Abstract: 954,934. Paper; paper-making. PAPPERSBRUKENS SERVICEAKTIEBOLAG. Oct. 16, 1961 [Oct. 17,1960], No. 36976/61. Addition to 909,501. Headings D2A and D2B. In changing the direction of movement of a travelling paper web, to increase its softness, flexibility and stretchability, the web is transferred from a conveying surface 11, Figs. 1 and 2, on to another conveying surface 13 at a location 17 in the nip 15 between the conveying surfaces, where they move in substantially opposite directions with the same or slightly different speeds and are spaced apart by a distance of the order of twice the thickness of the paper web, which is thus folded, i.e. turned substantially back on itself, along a fold line at the location 17. The conveying surfaces may be moved relatively to each other to vary the pressure at the nip. A steel blade may be inserted, or jets of air may be directed between the faces 19 and 21 of the paper web inside the fold. These faces are, preferably, brought into sliding contact, Fig. 2. A lubricant, such as powdered talc, may be fed into the fold, as by being applied, before folding occurs, to the face of the paper which does not touch a conveying surface. The lubricant may be retained in the fold by the said jets of air or by rotating brushes. An adhesion-improving substance, such as powdered rosin or resin or water in the form of spray or condensate from a surrounding atmosphere of steam, may be introduced between the paper web and one or both conveying surfaces, which may be heated. The paper web may be held in contact with one or both conveying surfaces by charges of static electricity generated frictionally on the paper web by allowing it to slide over a braked rubber roller, or by keeping the pressure of the atmosphere on the contacting face of the paper web lower than the pressure on its other face, as by applying suction. The paper web may be subjected to a plurality of changes of direction by bringing alternate faces of the web into engagement with, and transferring the web between, pairs of conveying surfaces. The resulting fold lines may be inclined at different angles to the edges of the web. The conveying surfaces may be pairs of cylindrical rollers, e.g. provided with inter-meshing rectangular teeth, or pairs of endless bands or parts of a single endless band or crossing sets of parallel threads or bands. Alternatively, one conveying surface may be a roller and the other an endless band. The paper web may be carried on an endless band into the nip between two rollers. One conveying surface may be a drying cylinder, e.g. a Yankee cylinder, of a paper-making machine. The conveying surfaces may be rigid, elastic or resilient, perforated, e.g. porous or foraminous, or unperforated.
