Title: Improvements in or relating to the production of pure carbon dioxide
IPC: C01B32/50
Filed: 1950-03-01
Abstract: <PICT:0671493/III/1> <PICT:0671493/III/2> Pure carbon dioxide is produced by oxidizing solid, liquid or gaseous carbonaceous materials such as charcoal, coke, coal or gaseous hydrocarbons such as methane, with excess hot metallic oxide such as ferric, cupric, stannic oxides or vanadium pentoxide, at a temperature below the sintering temperature of the oxide, but sufficiently high for the oxygen of the metallic oxide to react with the carbon to produce carbon dioxide.  A fluidized or moving bed is employed to contact the oxide with the carbonaceous material, the spent oxide being removed, regenerated by treatment with air, and recycled.  In Fig. 1, carbonaceous material such as coke is fed from vessel 2 to reactor 1 containing fluidized beds of regenerated oxide.  Pure carbon dioxide is withdrawn at 11, a small portion being recycled through line 14 to assist fluidization. Spent oxide is withdrawn from the lowest bed at 17 and is entrained in a stream of air in pipe 18 and passed to a regenerator 7 where it is regenerated by contact with air entering from pipe 21.  Ash is removed from the regenerator at 30 and the regenerated oxide is recycled to the reactor through line 9, carbon dioxide being employed as the entraining gas.  In the moving bed arrangement shown in Fig. 3, a number of alternate carbonaceous material and metal oxide containing chambers are provided and are fed by lines 5 and 6 respectively.  The chambers are connected severally by pipes 7 and 8 with respect to their solids content and serially in respect of gas flow.  A mixture of carbon monoxide and carbon dioxide, in part recycled from a point between the last two chambers through line 14, enters the lowest oxide chamber where the monoxide is oxidized to the dioxide which, passing to the superadjacent carbon containing chamber, is reduced to carbon monoxide.  The final chamber contains oxide and the effluent therefrom is pure carbon dioxide.  Spent oxide is withdrawn at 9 and passed to a regenerator to re-enter at 5, whilst the coke is withdrawn at 15 from the lowest carbon containing chamber, the ash removed at 13 and the remainder passed to the upper carbon chamber by line 10.

Abstract: 551,649. Resinous ethyl silicones. BRITISH THOMSON-HOUSTON CO., Ltd. April 24, 1941. No. 5310. Convention date, April 27, 1940. [Class 2 (iii)] Resinous polymeric silicones are obtained by hydrolysing a mixture of ethyl silicon halides containing an average of 0.5-1.5 ethyl radicles per silicon atom and dehydrating the hydrolysed product. The ethyl silicon halides are obtained by adding an ether solution of ethyl magnesium bromide to an ether solution of silicon tetrachloride. The mixture of ethyl silicon halides of the specified ethyl/silicon ratio may be obtained by suitably proportioning the two starting materials or by admixture of separately prepared halides.' In a modification, separated prepared halides are independently hydrolysed and then admixed before dehydration. The preferred ethyl range is 0.7-1.3. With higher ethyl content dehydration may be effected with the aid of dehydrating agents, as described in Specification 549,081. Products ranging from viscous liquids to horny, rubbery or brittle solid materials may be obtained. Partial polymers may be dissolved in solvents and applied to metallic conductors, with or without wrappings of asbestos, glass, cotton or paper, completion of polymerization being effected by heating. The products may also be applied to sheet insulations, as a coating for glass and for the production of laminated products, and may be compounded with other materials, as described in Specifications 542,655 and 544,143. Examples describe the formation of ethyl silicon halides and their further treatment in which the molar ratios of ethyl magnesium bromide to silicon tetrachloride are (1) 0.75, (2) 1 and (3) 1.25.

Title: Method for making tampons
IPC: A61F13/20
Filed: 1961-02-15
Abstract: 918,593. Tampons. RABELL, W. H. Feb. 15, 1961, No. 5622/61. Class 81 (2). A method of making a tampon comprises laying down a rectangular layer of cotton in flat condition, superimposing on it a layer of gauze, rotating the two layers through 90 degrees in the plane of the layers, laying a second layer of cotton on the gauze so that it lies at right angles to the first layer, applying a cord to the layers and pursing and compressing the layers during heating to form the tampon. Rectangular cotton pieces are cut from rolls 10, 20 by severing means 12, 22 and transferred by devices 14, 24 to a flight 16 of a conveyer where they are held in flat condition by suction devices. The conveyer moves step-wise and at the second station 34, rectangular pieces of gauze cut from rolls 28, 36 are superimposed on each cotton piece. As the pieces are moved to the third station 48 they are rotated by the suction devices through 90 degrees in the plane of the pieces. At the third station a second rectangular piece of cotton cut from rolls 44, 46 is laid on each piece of gauze thus forming a number of tampon blanks each consisting of outer layers of cotton and an intermediate layer of gauze. At the fourth station the blanks are repositioned so that at the fifth station 50 cords 68 may be affixed in the centre of each blank. The blanks are then passed to a turret 59 where they are heated, pursed and compressed to the required shape which may be fluted. After leaving the turret, the tampons are transferred to a second conveyer where they are cooled, inserted in pairs of telescopic cardboard applicator tubes 62, 64 and packaged.

Abstract: 307,344. Universelle Cigarettenmaschinen Fabrik J. C., M³ller & Co March 5, 1928, [Convention date]. Packeting cigarettes.-In shaping, filling, and closing slide and shell boxes, cigarettes are placed on a blank s simultaneously with the raising of the side walls w thereof, the folding of the slide is then completed and the completed slide is fed down an inclined track so that the projecting front edge of the slide enters a shell held open by a former which previously erected it as it was fed forward in the longitudinal direction of the slide. Cigarettes Z<1>, Fig. 2, from a container 1 are fed on to a plate. 8 disposed above a conveyer 7 which receives a layer of cigarettes Z' from a container 2. A finger 9 sweeps the upper layer of cigarettes on to the lower ones to permit the conveyer 7 to feed both layers on to a blank s disposed beneath a bridge 12, Fig. 3. The blanks s are fed singly from a pile 13 by a cam operated pusher 14 and rest against a stop 19<b> on a pusher 19. The pusher 19 is raised to fold up the side flaps w, Fig. 11<a>, of the blank, the bridge 12 being simultaneously raised. Projections 21 on a conveyer 18, carry the slide past folders 23, 24 which turn up the end flap and bend over the tongue 2, whereupon a conveyer 26 moving at right angles to the conveyer 18 moves the slide through a channel 28 thereby completing the folding of the slide. The channel 28, Fig. 7, leads to an inclined track 30 down which the slide is guided by the lower stretch of an upper conveyer band 31 until its rests upon a pivoted table or part 42 of the track 30. In the meantime, a collapsed shell h, fed from a pile 32 by a conveyer 34, is opened out by a knife edged former 35 restrained from movement with the shelf by one or more of a series of spring pressed pins 38 which engage recesses 37 in the former. As the shell progresses along the former, the pins are removed from its path and later returned to hold the former. The former holds one end of the erected shell whilst the projecting front edge of the slide enters the other end; the table 42 is lowered to bring the slide into line with the shell and the conveyer 34 pushes the shell over the slide. A pusher 46 depending from a chain 47 passes the completed box on to a delivery conveyer 48.
