Title: Process for the prodution of acetic acid or mixtures of acetic acid and methyl acetate
Inventor: HOHENSCHUTZ HEINZ
IPC: C07C51/12
Filed: 1961-01-20
Abstract: In a process for the production of acetic acid or mixtures thereof with methyl acetate, by reaction of carbon monoxide with methanol, methyl acetate, dimethyl ether or mixtures of these compounds at elevated temperature and pressure in the presence of a catalyst, waste gas withdrawn from the reactor is washed with methanol or methyl acetate and the solution obtained is returned to the reactor to reduce loss of catalyst and other valuable material.  The catalyst may be elementary or combined halogen, e.g. iodine, and metals or metal compounds.  Carbon monoxide is circulated through the reactor, a portion being removed as waste gas to remove inert gases, e.g. carbon dioxide and methane, which are formed by side reactions.  The waste gas is cooled to -30 DEG  to +30 DEG C., the pressure reduced to within the range from normal pressure to 10 atmospheres gauge, and the gas washed in a tower. Any gas set free from the washing solution also may be washed.  In an example a mixture containing methanol, methyl acetate, higher esters, water, acetic acid, hydriodic acid, methyl iodide and cobalt acetate, is reacted with carbon monoxide at 230 DEG C. and a pressure of 650 atmospheres absolute; the product and gas leaving the reactor are cooled and the product separated from the gas; most of the gas is recycled, a portion being washed with methanol and the solution obtained mixed with the water, methyl acetate, unreacted methanol and catalyst which are recovered in working up the acetic acid, and the mixture returned to the reactor.

Title: Improvements in railway-vehicle couplers
IPC: B61G3/16
Filed: 1925-01-27
Abstract: 241,774. White, A. E., (National Malleable & Steel Castings Co.). Jan. 27, 1925. Couplings, automatic.-In a car coupler having two rigid, laterally-separated. oppositely-disposed jaws 3, 4, and a lock 9 movable in a cavity 10 extending longitudinally between the jaws, the lock is adapted to be positively actuated by a lever arm 15 to move it into a retracted unlocking position and into lock-set position, the lock having a projection 22 co-operating with a recess 24 on the coupler for supporting the lock in lockset position. The projection 22 on the lock is adapted to slide in a groove 23 formed in the inner face of the buffing jaw 3, the recess 24 being provided for the projection 22 when in lock-set position. One side of the lock 9 is recessed, shown by the irregular line 18, 14, 19, 21. Fig. 2, and in the recess works the arm 15 of a U-shaped lever 15, 16 pivoted on a bolt 13 and manually operated by a rod 16a to retract the lock for uncoupling or lock-setting; the other side of the lock is provided with projections 27, 29 adapted to bear on the wall 28 to maintain the lock in vertical position, and a curved tail 12 provides a guide and also limits the forward movement of the lock. To retract the lock from the coupled position, Fig. 2, the rod 16a is moved rearwardly to raise the arm 15 so that its surface 20 engages the recessed surface 21 of the lock to move the lock upwardly and rearwardly until the uncoupling position, Fig. 3, is reached, where the projection 22 on the lock is beyond the recess 24 and the lock is supported on the arm 15 at 19. In this position the centre of gravity of the lock is to the rear of the point 19 so that the front of the lock tilts upwardly, and when the lock is released the projection 22 enters the recess 24, which is the lock-set position of the coupling. The lower part of each lock is bevelled so that, as the couplings draw apart, the forward edge of the look which has not been retracted sweeps across the face of the other to squeeze it rearwardly to dislodge it from the lock-set position so that it shoots forwardly into the looked position ready for the next coupling of the vehicles. If the couplings are not on the same level, the look remains in its lock-set position and is only dislodged by the buffing face or lock of the opposing coupling at the next automatic coupling. When the lock is in the locked or extreme forward position the arm 15 is behind the surface 18 of the lock so that the lock is prevented from moving backwardly to the extent of unlocking the coupling.

Patent GB-757073-A (GB)
Title: Textile printing process
IPC: D06P1/00
Filed: 1953-01-30
Abstract: Cellulosic textiles are resist-printed by applying locally a thickened resist paste containing one or more water-soluble salts of Ca, Ba, Sr, Al, Sn, Sb, Zn, Cd, Fe or Mn such as water-soluble chlorides, sulphates, acetates, nitrates or thiocyanates, then padding the textile with an alkaline solution of the leuco compound of a vat dyestuff and then with a solution of a reducing agent, heating at 95 DEG -105 DEG C. and subsequently oxidizing the leuco compound to the vat dyestuff.  If the paste is to contain an oxidizing agent, a salt of one of the above metals with an acid which is itself an oxidizing agent, e.g. m-nitrobenzene sulphonic acid, may be employed.  The paste may be thickened with British gum, gum tragacanth, gum Seregal, Natha Crystal gum, Locust-bean gum, starch or an alkyl cellulose such as methyl or methylethyl cellulose, or it may be thickened by forming it into an oil-in-water or water-in-oil emulsion.  White resists may be obtained by the addition of zinc oxide, titanium dioxide or china clay to the paste.  Coloured resists may be obtained by the addition of azoic combinations to the paste, or the textile may be preheated with the coupling component, in which case the paste contains a stabilized diazo compound, the dyestuff being developed by neutral steaming prior to vat dyeing.  Coloured resists may also be obtained by the addition to the paste of a pigment and a resinous binder, or of a dyestuff containing a quarternary or ternary salt group of the kind described in Specifications 576,234, 576,270, 587,636 [all in Group IV] and 613,980, together with printing assistants such as lactic acid, acetic acid and sodium acetate.  Alternatively, leuco sulphuric ester derivatives of vat dyestuffs, together with developers such as sodium chlorate, ammonium thiocyanate and ammonium vanadate, may be added to the paste, and the printed textile steamed to develop the print prior to the vat dyeing strip.  In addition to the resist printing the textile may be printed alongside the resist paste with oxidation dyes.  When the pigment padding process is employed for applying the vat dyestuff fixation is preferably effected by heating in steam, molten metal or hot oil, as described, for example, in Specifications 599,296 [Group IV] and 620,584.  When the leuco compound is padded on the textile prior to heating, it may be applied in the apparatus of Specification 620,584 Numerous examples are given.
