Title: Improvements in methods for cutting and burnishing spherical surfaces and apparatus therefor
Inventor: GOTTSCHALD RUDOLF
IPC: B24B11/00
Filed: 1967-03-10
Abstract: 1,113,089. Ball turning; rolling. V. LANGEN, [trading as A. EHRENREICH & CIE]. 10 March, 1967 [22 March, 1966], No. 11375/67. Headings B3B, B3M and B3T. A ball turning and burnishing machine comprises a chuck 1 on which a workpiece 2 is mounted and which is rotatable about an axis a, a table 6 rotatable alternately in opposite directions about an axis b which intersects the axis a at a point defining the centre of curvature of the ball', a cutting tool 8 mounted on the table to one side of the axis a and a burnishing tool 11 on the other side of the axis a, diametrally opposite the cutting tool. Operation.-With the table 6 in the position shown in the Figure the tool 8 is moved hydraulically to apply the cut and the burnishing roller 8 is retracted from the workpiece. The table is rotated in the direction of the arrow 13 and the workpiece rotates about the axis a, to form a spherical surface. When the tool 8 reaches the position 8<SP>1</SP>, the tool holder contacts a stop (not shown) which causes the table to stop, the tool to be retracted and the burnishing roller 11 which is now in the position 11<SP>1</SP> to be advanced into contact with the work. The table 6 then rotates in the opposite direction so that the burnishing tool works the turned surface.

Abstract: 707,073. Gasifying powdered fuels ; oil gas generation. KOPPERS GES., H. May 17, 1951 [May 23, 1950], No. 11579/51. Classes 55 (1) and 55 (2) In gasifying finely divided coal, lignite, peat, coke, hydrocarbon oils &c. to produce gases rich in carbon monoxide and hydrogen, a suspension of the fuel in gas containing oxygen and an endothermically reacting medium such as steam or carbon dioxide the temperature of which is below 100‹ C., is injected as a jet into a reaction chamber maintained at ignition temperature, the proportions of the mixture and its rate of flow being such that the heat of the reaction between part of the carbon and oxygen is sufficient to raise the temperature of the components to 1200‹-1600‹ C. and to cover the heat consumption of the endothermic reaction of the remainder of the fuel. Finely divided coal &c. mixed with oxygen and steam is admitted through an injector nozzle 4 into an inlet reaction chamber 1, steam also being introduced through an annular series of inclined nozzles so as to form a helically moving protective layer or envelope. Reaction products entering a second reaction space 6 react with slightly superheated steam or atomized water injected through nozzles 9 to increase the hydrogen content at the expense of the carbon monoxide. Unburnt residue or ash is discharged through an opening 8. Specification 673,161 is referred to.

Patent GB-899829-A (GB)
Title: Laminates and particularly laminated foils and process for their production
IPC: A23L3/3427
Filed: 1960-04-01
Abstract: A laminate comprises a layer of a metal and a layer of a film-forming polymer of an aliphatic 1-olefine having from two to eight carbon atoms, bonded by an intermediate layer of a polyalkylenimine.  The metal may be aluminium, lead or an alloy and may be in the form of a film or foil or of thicker sheets, or may be paper-backed.  The olefine polymer may be polyethylene of the high-density or of the low-density type, or polypropylene, or polybutylene-1.  The polyalkylenimine may be a polymer of which the alkylene units contain two to four carbon atoms, e.g. polyethylenimine.  It is preferably of the water-soluble kind and applied in solution in a volatile solvent, e.g. acetone, methyl ethyl ketone, methyl isopropyl ketone, or a lower alkyl alcohol such as methanol, ethanol or isopropanol, which is allowed to evaporate before the polyolefine layer is applied. This may be done immediately after evaporation of the solvent, or the polyalkylenimine-coated foil may be rolled up, for subsequent coating with polyolefine.  The polyolefine may be applied in a molten condition.

Abstract: 336,601. O'Neill & Sons, Ltd., S., and Pearson, J. E., (Gilis, P.). April 16, 1929. Pirns or tubes.-In the manufacture of paper pirns or tubes of varying taper, particularly applicable to pirns as shown in Fig. 6, having an acutely tapering part a on which is superposed a less acutely tapering part h, the parts a and h are formed of separate pieces of paper, the part a being wound on a mandrel and the part h tucked in as shown in Fig. 5, and wound on, the whole being secured by adhesive. The parts a are cut from a strip o, Fig. 8, of paper from a. roll O which is fed over a supporting face 305 covered with flannel and is printed upon by a type block 299. Adhesive is applied along one edge by a grooved wheel 293 dipping in a trough 294. A brush 295, Fig. 7, is used to remove excess of adhesive. The printed and gummed paper strip then passes through rollers 283, 284, over a roller 334 and through rollers 257, 258 grooved to receive guide wires 261, Fig. 7, to guide the paper to the cutters p, u, 29 by which the edges c, g, b, e and b, d, Fig. 3a are produced. The piece of paper a so obtained is seized by grippers 67<a>. 66<a>, Fig. 12, and carried thereby to the mandrel 138 and released, the traverse of the grippers being effected by a cam 82 operating on a lever 84 which through a spring link 87 reciprocates a block 68 on which the grippers are mounted, release of the paper being effected by depressing an arm 81 of a detent 75 by a lever 79 operated by a cam 78. When the paper a is wound up mto the condition shown in Fig. 5, a piece of paper h from a pile H, Fig. 14, is lifted by a suction plate 153 connected to a suction pump by pipes 159, 161, and carried with its wider end into position to be wound up with the remaining unwound lip of the piece a. Adhesive for the winding of the paper is supplied by a brush 200 having a gumming part 199 extending over the length of the pirn, a gumming part 201 extending over the length of the part h, and a part 200 extending over the whole length for removing the excess of adhesive. The finished pirn is stripped from the mandrel and falls through the table 9 into a suitable receptacle. The type block 299, Fig. 8, is inked by a roller 300 made to rise and fall to and from a roller 301 revolving in contact with a roller 302 which forms one side of a bath of ink. 'The blades p, u, and 29 are moved by cams or tappets 35, 36, 37, Fig. 7, against the action of springs.

Abstract: Phosphonitrilic halides are reacted with amines of the formula RNH.R1.NHR11, where R1 is aliphatic and has 3 to 18 carbon atoms, and R and R11 are the same or different and may be H or an aliphatic radical having 1 to 18 carbon atoms, aliphatic including non-aromatic cyclic radicals. The phosphonitrilic fluorides, chlorides, bromides or mixed halides, as trimers, tetramers or oily or rubbery polymers may be used as may partially hydrolyzed phosphonitrilic halides or halides having some halogen atoms replaced by amino groups.  The preferred diamines are those in which R1 has 5-8 carbon atoms. Preferably 0.25-3 mole of diamine are used per gram atoms of phosphorus, and the reaction preferably conducted in a solvent for the reactants (e.g. ether, tetrahydrofuran, or dioxan), preferably between room temperature and 100 DEG C.  A solution of the amine may be added to a solution of phosphonitrilic chloride in an ether, the amine hydrohalide removed, e.g. by filtration or extraction with water, and the ether evaporated to yield polymers which may be purified by solution in benzene, ether, methanol, acetone, or tetrachloroethane, precipitation by addition of petroleum ether, and removal of remaining solvent in vacuo. Alternatively, in ethaneal solution of the amine is mechanically worked into a rubbery phosphonitrilic halide, or an aqueous solution of amine is shaken with a solution of phosphonitrilic chloride in a water-immiscible solvent (e.g. ether or benzene). Residual halogen in the products may be replaced for example by heating with ethylene imine or dimethylamine. The products are thermoplastic and can be formed and moulded by heating to 60-220 DEG C., and may be used as adhesives for wood, glass. and cellulose.
