Abstract: 1469320 Making pipe bends; stamping HERMANN MULLER GmbH 27 June 1974 [18 Aug 1973] 28484/74 Headings B3A and B3Q The first of two forming operations for making a pipe bend from sheet metal is performed with a punch 3 and a die 2, Figs. 1a 1b, having a holddown 14 movable with the punch 3, and diesegments 8 movable radially of the die-cavity to form the blank 1 into U cross-section. Further apparatus, Figs. 7a, 7b, then forms the U into circular cross-section after which a longitudinal seam weld is formed and the ends of the bend trimmed. Hold-downs 14, Fig. la, at each end of the punch 3 are interconnected by bolt 15 and pass with the punch between side walls 4 of the die to clamp margins of the blank against lands 7 in the die-cavity, Fig. 4a (not shown). Continued movement of the ram forms the back of the pipe bend with the die-segments 8, operated by hydraulic pistons, in the extended position, Fig. 4a. Further movement of the ram pushes the segments 8 into the die, Fig. 5a (not shown), to complete the first operation when the work is ejected by an ejector 10. The work is now placed on the support 16, Figs. 7a, 7b, of the second apparatus which includes a curling die 18 and an arcuate mandrel 17 the two halves 17a of which are mounted on links 23 for turning about a pivot 24 to withdraw the mandrel. As the die 18 and mandrel are lowered the edges 1a, Fig. 7b, of the blank curl in the gap between the die and mandrel until the mandrel contacts the bottom of the blank. A small further movement of the die 18 now closes the gap, Fig. 8a (not shown), between the top of the now stationary mandrel and the inside of the pipe bend to complete the second priming operation, Fig. 9a.

Title: Improvements in or relating to production of carbon black and apparatus therefor
IPC: C09C1/48
Filed: 1954-10-04
Abstract: <PICT:0766281/III/1> In the production of black by introducing a make hydrocarbon into a spirally rotating stream of combustion gas produced by injecting a combustible mixture tantentially into a carbon black furnace, the make hydrocarbon is introduced into the furnace from a plurality of tubes, e.g. 14 arranged substantially parallel to the axis of the furnace.  The tubes which may be at a slight angle towards the axis of the furnace, are arranged so as to avoid impingement of the hydrocarbon on the inner walls of the furnace. A combustible gas mixture may in addition be introduced axially into the furnace and said make hydrocarbon tubes spaced symmetrically around the inlet therefor.  The make hydrocarbon may be a degraded highly aromatic recycle gas oil produced in a cracking process, kerosene, gasoline, heavy or light naphtha, or natural gas. A liquid make hydrocarbon may be used in atomized liquid or vapour form.  A gaseous fuel is usually employed in the combustible mixture but atomized or vaporized oils may also be used.  As shown the furnace comprises an oxidation chamber 11 having tangential inlets 14 and axial inlet 15 for a combustible gas mixture.  Make hydrocarbon is injected into the oxidation chamber through four inlet tubes 16, each of which is surrounded by a water jacket 17 spaced therefrom so as to form an annular air space.  The oxidation chamber 11 continues in the form of an elongated chamber 10 of smaller diameter wherein the carbon black forming reaction is completed.  Tubes 15 and 16 may be longitudinally movable.  Specification 679,818 and U.S.A. Specification 2,564,700 are referred to.

Abstract: 772,125. Filling valve-bags. SMIDTH & CO. AKTIESELSKAB, F. L. Oct. 6, 1955, No. 28512/55. Class 94(1). [Also in Group XXX] In a method of, or apparatus for, filling valve-bags with granular or pulverulent material in which the material is fluidized by aeration in a tank and discharged from it through spouts into the bags, the air pressure above the material in the tank is maintained higher than atmospheric. Fig. 1 shows a rotary, cylindrical tank 1 carrying filling spouts 5 and mounted on a shaft 2 driven by a worm wheel 4. The spouts are fitted with valves controlled by mechanism for weighing the bags. The material is supplied to the tank from a hopper 11 through a pipe 24 which fits closely into a central opening in the top of the tank. The material in the hopper and tank is fluidized by compressed air admitted through porous walls 6, 9, 10 and 13, the air pressure above the material in the tank being determined by the head of fluidized material above the bottom of the pipe 24. The rates of admission of air at the various levels may be adjusted by means of valves in the supply pipes, or the porosity of the walls 6, 9, 10 and 13 may decrease progressively. Compressed air is also admitted to a chamber 12  to prevent entry of dust into the seal between the pipe 24 and tank 1. In a modification, Fig. 2, the worm wheel 4 is located above the tank 1 and the hopper is offset from the axis of the tank, the supply pipe passing through a stationary cover 15. Seals 25 are provided between the cover, the shaft 2 and the top of the tank, and as these are not air tight compressed air is supplied through a pipe 16 to maintain an air space beneath the cover. In Fig. 3, the material is supplied to a stationary tank 1 from a hopper 11 by a worm 20 controlled by a level indicator 18, fluidizing air being admitted to the tank through porous walls 6. The air pressure above the material in the tank is determined by a relief valve 17. Fig. 4 (not shown) illustrates a modification comprising a rotary tank.

Abstract: 1,271,294. Metal coating fibres by carbonyl decomposition. J. P. GLASS. April 1, 1969 No.28797/71. Divided out of 1,271,291. Heading C7F. [Also in Division C1] A whisker or whiskers e.g. of sapphire, alumina, and carbon, are grown by introducing a vapour mixture containing a whisker forming material into a reaction chamber, crystallizing the vapour mixture to deposit the whisker forming material on to the tip or tips of one or more whiskers projecting into the reaction chamber to form a substrate, and depositing metal from a gaseous mixture or compound on to the growing whisker or whiskers at a sufficient distance from the growing tip or tips to avoid interfering with such growth, electrically charging said projecting whisker or whiskers so as to maintain it or each of them in an extended condition and if there is more than one to effect a fanning out of the projecting bunch of whiskers and withdrawing the whisker or whiskers as they grow, the bunch of whiskers if there be a bunch, being gathered together where they leave the chamber for withdrawal from it in the form of a strand. The gaseous metal mixture or compound is preferably a metal carbonyl e.g. of Fe, Co, Nu, Mo or K, which decomposes to give the metal. A body may be produced from the metal coated whiskers so produced by shaping a plurality of these metal coated whiskers, heating so the metal melts and enmeshes the whiskers and then cooling the element so the metal hardens and bonds the whiskers together. A particular metal clad whisker disclosed is sapphire coated with iron. In a particular embodiment shown in the Fig., a fibrous substrate is supported on thimbles 231, in bushing 239 spaced from the base of the chamber 221 through which the strand or whisker is withdrawn. The whiskers are spread and maintained erect by charging partition 225. Metal containing vapour is introduced through conduits 255 into thimble 231 and percolates through the bushing 239 and vents 241 to the bunch 249 of fibres. The thermal conditions in chamber 221 are such that the metal is deposited some distance away from the growing tips. Vapours from the reaction chamber may be recycled back into contact with the fibre through hollow partition 243, and the temp may be maintained in chamber 221 by introducing heated air from chamber 223, Fig.2 (not shown) through vents 227. Heating element 257 also heats the chamber and prevents unwanted nucleation on the walls.
