Title: Improvements in the manufacture and production of acetaldehyde and acetic acid
Filed: 1930-11-14
Abstract: In the production of acetaldehyde or acetic acid or mixtures thereof from mixtures of acetylene, water vapour, and oxygen by passage over a hydration catalyst at elevated temperatures, the mixed gases are laden with mercury vapour by passage over or through mercury heated to about 300 DEG  C., and the whole then passed over the catalyst, which may be heated to 100-300 DEG  C.  The mercury is then separated, as, for example, by cooling.  Gas mixtures poor in acetylene may be treated in this way.  As catalysts, mercury compounds, e.g. mercuric phosphate, or mixtures thereof with salts of any other heavy metals, or with metal oxides, or non-volatile acid inorganic compounds, such as phosphoric, sulphuric, phosphotungstic, and tungstic acids, or acid salts thereof or of boric and chromic acids, may be used, if desired on carriers such as active carbon, clay sherds, pumicestone, kieselguhr, porous glass masses, and silica gel.  To the catalysts may be added metal compounds such as aluminium oxide, chromium sesquioxide, zinc oxide, ferric oxide, mercury oxide, vanadium pentoxide, manganese dioxide, molybdenum trioxide, and cerium oxide or metal salts such as chromium phosphate, ferrous sulphate, zinc phosphate, aluminium nitrate, tin vanadate, zinc acetate, or other salts derived from the oxides and the non-volatile acids specified above.  Examples of the process of the invention, and also comparisons of the results obtained with those of processes in which mercury vapour is not used, are given.
Patent GB-343743-A (GB)
Abstract: 343,743. Circular knitting-machines. SPIERS, Ltd., W. and SPIERS, W., XL Works, Walnut Street, Leicester. Feb. 19, 1930, No. 5527. [Class 74 (ii).] To prevent the loose end of yarn present during yarn-changing from interfering with the knitting operation by becoming entangled with the latches, the rib needles of a superposed cylinder or other machine are caused temporarily to tuck or form a partial welt at such times, whereby the loose end is bound or knitted in. A group 2 of rib needles or of needle-actuating sliders 3, where doubleended needles are used, is provided with shorter butts than the remaining needles or sliders 4. The existing welt cam is partially withdrawn simultaneously with a yarn change, so as to miss the group 2, by a slidable cam block 5 with stepped inclines 6 engageable with a pin &c. 7 on or in the stem 8 of the welt cam. The block is operated from the main control drum 11 by connections 9, 10. Preferably the block 5 is also connected with the yarn changing means, which may be of the kind described in Specification 322,282 ; [Class 74 (ii), Knitting &c], by a link 14, which acts on the pawl lever 17 through connections 18, 15 and also acts on a nose 23 on a lever 21, connected by a link 22 to the block 5. The link 22 carries a pin 25 engaged by the lever 21 and passes through a hole in another pin 26, carried by a lever 27 mounted on an existing rock shaft 28 controlled by an arm 29 and lever 30 from the drum 11. When a partial welt is not to be formed (e.g. in the production of plain or broad rib fabric) the parts 30, 28, 27 are operated to move the link 22 and its pin 25 out of the path of movement of the lever 21. Specification 345,609 also is referred to.

Title: Improvements in or relating to furnace carbon black production
IPC: C09C1/48
Filed: 1953-12-14
Abstract: <PICT:0748585/III/1> <PICT:0748585/III/2> In a process for producing furnace carbon black where the carbon black is recovered from the furnace effluent at at least in part in an electro - precipitator, oil is continuously passed into the oil seal compartment of the electro-precipitator, and the oil overflowing from the oil seal compartment is withdrawn and introduced into the carbon black production furnace as part of the oil feed to the furnace.  Oil is fed to tank 13 for settling of suspended solid and liquid matter, and oil freed from suspended matter passes to tank 17, whence it is passed by line 19 to manifold 23 as axial feed to furnaces 27.  Air or air and combustible gas is fed into the furnaces tangentially by manifold 25.  Effluent gas containing carbon black is quenched by water sprayed from manifold 31, and passes through 29 to eletro-precipitator 33.  Current from source 39 passes to wall of precipitator 35 and to oil seal compartment 37 and thence to electrodes 35 to impart a charge to the carbon black causing agglomeration.  The effluent passes on to cyclones 41, 43 and bag filter 45.  Carbon black from the various separators is collected in conduit 57.  Pipe 61 takes oil from pipe 19 to oil seal compartment 37, whence it overflows to surge tank 63 through pipe 59.  Oil from tank 63 is pumped back through pipes 65, 69 to tank 17 or may be pumped directly into the furnace feed through pipes 65, 67. Alternatively oil may be fed to compartment 37 from tank 13 through pipes 15, 61 and returned to tank 63.  In an alternative precipitator (Fig. 2, not shown) the electro-precipitator is a wet precipitator provided with oil or water sprays and is followed by a spray vessel. A slurry is withdrawn from both vessels.  One or more of the separators 41, 43, 45 may also be operated as wet separators.  In Fig. 3 the oil seal compartment of the electro-precipitator has walls 101 which with bottom 117 form a container for a pool of oil 123. Current passes by lead 103 supported on insulator 105 to support 111 for electrodes mounted in the compartment 133 below, which is mounted on insulators 107.  High tension rapper 113 is provided for jarring carbon black from the electrodes.  Bell 121 rigidly attached to support 11 projects into oil pool 123 and prevents carbon black in the effluent in electrode space 133 from being deposited on the terminals and causing short circuits.  Oil is fed into the oil seal through 127 and withdrawn through 125.  It is stated that, in known arrangements to prevent carbon black deposition, inert combustion gases have been fed from pipe 115 into annular space 131 and passed out under bell 121 down into the electrode compartment, but this arrangement is not necessary in the present process.  Specification 621,031 is referred to.
