Title: Improvements in the pelleting of carbon black
IPC: C09C1/58
Filed: 1957-10-28
Abstract: <PICT:0824589/III/1> <PICT:0824589/III/2> Beads of carbon black having high resistance to crushing and packing, are prepared by wetting the surfaces of preformed dry process beads as defined having a bulk density of at least 20.5 lb. per cubic foot, with water in proportions of 40-90 lb./100 lb. of dry-process beads, and thereafter drying the beads to a moisture content not exceeding 1% by wt. Dry process beads of density 21-22 lb./cubic foot are produced by tumbling carbon black either dry or containing 4-33 wt. per cent of water in a rotating drum 1, the black being introduced at 2.  Beads leaving drum 1 are preheated if desired to 500 DEG  F. to ensure production of dry-process beads of the correct density but in any case are conveyed by 5 into a rotating wetting drum 6.  Water preheated to its boiling point or containing surface-active agents or binders, if desired, and in the form of a coarse spray and preferably of an elliptical pattern, with the greater axis parallel to the longitudinal axis of the drum, is mixed with the beads in proportions preferably 50-60 lb./100 lb. of beads, so that only the outer portion of the beads to a depth not exceeding 1/4 -\ba1/3 of their diameter is wetted.  The wetted beads pass from 6 through outlet 10 into hopper 11 and thence by conveyer 12 to drier 13.  The depth of the bed of beads in 6 is determined by the height of the dam 14.  Drier 13 consists of a rotary cylindrical drum 15 heated externally by burners 16 and enclosed by shell 17.  Hot combustion gases from 16 pass around 15, and exit at 18 through heat exchanger 19 which serves to preheat drying air introduced in counter-current to the moving bed of beads in 15 by pipe 20.  Effluent air conduit 21 leads moisture-laden air through exhaust blower 22 to the atmosphere. The depth of the bed of beads in 15 is determined by the height of dam 25.  Beads entering the drum 15 are heated rapidly to 220 DEG  F. maintained at this temperature until the beads are halfway through the drum when the temperature is rapidly increased to 400 DEG  F. and maintained at this temperature until exit through the shielding hood 23 to be discharged by conveyer 24.  Thermocouples positioned at intervals in the bed of beads record and regulate the temperature gradient.  Reference is also made to carrying out the wetting and drying stages in a single drum.

Title: Improvements in or relating to the manufacture of artificial filaments, threads, yarns and like materials
IPC: D06M11/38
Filed: 1933-12-01
Abstract: Filaments, threads, yarns and the like of organic esters of cellulose are subjected to partial deep-seated saponification by an organic base in the liquid phase, thereafter softened with an agent capable of softening the unsaponified materials, and then stretched.  A definition of partial deep-seated saponification is given. Preferably the saponified materials are drawn through a bath containing a softening agent for the unsaponified materials, and stretched during their passage through the bath.  Suitable saponifying agents are ethylene diamine, monomethylamine, ethylamine, propylamine, amylamine, triethylamine, trimethylamine, allylamine, tetramethyl ammonium hydroxide, sym. dimethyl ethylene diamine, monomethyl ethylene diamine, propylene diamine, 1, 2, 3-triamino propane, and a g -diamino-b -hydroxy propane.  The extent of saponification may be sufficient to remove 8 to 25 per cent of the acidyl content.  Aqueous concentrations of 15--25 per cent, temperatures of 15--35 DEG  C., and times of treatment of 1 to 3 minutes are mentioned.  For the softening, the following agents are specified, acetone, mono- and di-methyl ethers of ethylene glycol, dioxane, and methylene ethylene ether. The materials may be stretched to 150 to 200 per cent or more of their original length.  In an example, cellulose acetate yarn is led in warp formation through a 15--30 per cent aqueous solution of mono-methylamine (or ethylene diamine) to remove 15--25 per cent of the acetyl content, washed and dried, passed through a 40 to 50 per cent aqueous solution of acetone, and stretched.  In another example, cellulose acetate yarn is saponified by means of aqueous mono-methylamine so as to effect a loss in weight of 5--8 per cent, is softened by means of 35--40 per cent aqueous dioxane, and stretched to between 150 and 300 per cent of its original length.  The Provisional Specification refers to a process for stretching partially saponified filaments, threads, yarns and the like in the presence of softening agents.  Suitable saponification processes include saponification by means of organic bases, saponification in the presence of solvents or swelling agents for the cellulose ester, saponification in the presence of an alcohol, and saponification in the presence of egg-albumen, casein, or other albuminous substances.  Specifications 207,562, 277,089, 323,790, 330,950, [all in Class 2 (ii)], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 371,461, 378,858, 389,823, 392,185, 402,143, 403,071, 415,412, 417,220, 423,096, 423,168, and 429,103 are referred to.

Title: Pipeline systems
IPC: A01G25/00
Filed: 1971-07-20
Abstract: 1353820 Pipe couplings; pipe stoppers KUPEX AG 20 July 1971 [21 July 1970] 33866/71 Headings F2G and F2P In a pipeline system, e.g. an underground irrigation system connected to a mains water supply, successive lengths of plastics pipe are connected by a coupling in which a connecting ring 78 is compressed into a recess 72 adjacent the pipe ends by a coupling nut 84 screwed on a connector body 12. A number of readily disconnectible couplings 19, accessibly located in housings (14) (Figs. 1, 2, not shown) which open at ground level, are installed along the pipeline at limbs 13 of T-shaped coupling bodies 12. Each of the couplings 19 includes a shut-off valve 38 which is opened upon connection of a hose connector 16 with a nipple 20 of the coupling 19. As shown in Fig. 6, the connecting ring 78 which has a conical surface 79 and a flange 80 and may be of PVC or polyethylene, is snapped over the pipe end into the recess 72 to conform thereto and to abut a sharp shoulder 73. An insert 76 which may be of polyamide plastics strengthens the pipe end at the recessed portion and the pipe end is received within a conical bore 83 of the connector body 12 which wedges the ring 78 against the pipe when the nut 84 is tightened. The pipeline system includes stopped pipes and elbows formed by stopping one branch of a T-piece connector body 12. A pipe stopper is provided which includes a blanking piece 28 damped to the connector body end 81 by a nut 84 wherein a sealing 0-ring 88 is pressed axially against a projecting rim 89 on the body 12 and is prevented from collapsing radially by a flange 85 on the blanking piece 28. As shown in Fig. 5, the readily disconnectible hose coupling 16, is pushed on to the nipple 20 of the coupling 19 installed at right angles to a pipe coupling body 12 at a portion 13 thereon. The connector 16 depresses a sleeve 31 against the force of a spring 47 to bring openings 43 in the valve body 38, which is carried by the sleeve 31 by pins 48, clear of a narrow bore 37 in the coupling 19. 0-rings 42, 45, 46 seal the valve in the bore 37. Locking elements 60 located in a sleeve 63 on the hose connector 16 snaps into a peripheral groove 50 in the nipple 20. To disconnect the coupling, the sleeve 63 is rotated against the force of a torsion spring 64 until a fulcrum portion 66 on the elements 60 can locate in recesses 65 around the bore of the sleeve 63 to allow the coupling to be pulled-off. The housing (14) (Fig. 2, not shown) in which the couplings 19 are located, has a double wall and a flap lid (17). An open-cell, plastics foam filling (30) is placed at the bottom to prevent dirt ingress to the movable sleeve 31 and may be removed for cleaning. All parts of the pipeline system may be of plastics material.

Abstract: 494,059. Mercury switches. CHILOWSKY, C. Dec. 8, 1937, No. 33957. Convention date, Dec. 12, 1936. [Class 38 (v)] A switch comprises a column of mercury about 4 mm. in diameter in a tube with porous plugs arranged to minimize the risk of the breaking of the mercury column, and to ensure immediate restoration of its unity, when subjected to shocks. Fig. 1 shows the switch applied to a photo-relay of the type described in Specification 463,994 wherein the pressure changes produced in a bulb 1 by the action of light and by electrolytic action are transmitted through a diaphragm 6 held between two plates 7 and 8 and a tube 10 to a U-tube 11 which tube is provided near the ends with porous plugs 12<1>, 12<11> carrying contacts 13<1>, 13<11>, which are permeable to gases, but which limit the movement of bodies of mercury 14<1>, 14<11>. Communication between the two bodies of mercury 14<1>, 14<11> is established through a capillary bore 17 of a tube 18, which bore is continued by metal tubes to bring the open ends 16<1>, 16<11> into the centre of the bodies of mercury, which arrangement prevents the passage of gas from one limb to the other. With columns of mercury of diameters less than 3 mm., to aid the restoration of the unity, communication to allow the passage of gas between the two ends of the tube may be established by a wire or tube 30 disposed as shown in Fig. 6, by providing channels in the tube wall, by making the tube of a section with sharp angles, or by roughening its inside surface.

Title: Compressed air breathing apparatus
IPC: A62B9/02
Filed: 1953-12-07
Abstract: 743,767. Respiratory appliances. HAMPTON, T. A. Dec. 2, 1954 [Dec. 7, 1953; June 21, 1954], Nos. 34024/53 and 18198/54. Class 81(2). In a device for controlling the supply of air for breathing during diving, a reducing valve reduces the pressure to a low intermediate value and a demand-actuated low pressure valve controls the supply from this to a breathing chamber. Both valves avoid the use of mechanical linkage and are arranged to maintain the pressure in the breathing chamber equal to that of the surrounding medium. In the equipment shown, high pressure air enters a compartment 4 through a union 5 and thence passes to a low pressure compartment 6 through a reducing valve 8, which is controlled by a diaphragm 10 influenced by the low pressure air on one side and by the pressure in the breathing chamber 16 on the other. This chamber is closed by a flexible diaphragm 17, the outer face of which is subject to the pressure of the surrounding medium, and which tends to close the low pressure valve 21, between the low pressure chamber 6 and the breathing chamber 16. Air enters the breathing chamber until the pressure is equal to that of the surrounding medium, at which point the pressure of a spring 22 is just sufficient to hold the valve 21 closed. Either an inhalation by the user or an increase in ambient pressure will lift the low pressure valve off its seating and pass air to the breathing chamber 16 and any increase in pressure in the breathing chamber, resulting from the second cause, is communicated to the diaphragm 10 and thus raises the pressure in the chamber 6 accordingly. Other forms of low pressure valves, described with reference to Figs. 3 and 4 (not shown) comprise, in one case, a ball valve actuated by a flexible diaphragm and, in the other case, a tapered seating engaged by a conical boss formed on the diaphragm.
