Abstract: 1,169,241. Separating carbon dioxide from methanol synthesis gas. METALLGESELLSCHAFT A.G. 20 Jan., 1967 [22 Jan., 1966], No. 3099/67. Heading B1L. [Also in Division C2] In the synthesis of methanol wherein synthesis gas is obtained from light hydrocarbons such as light petroleum or natural gas, by cracking with oxygen or steam, carbon dioxide is partially removed from the synthesis gas stream. Thus, hot synthesis gas from cracker I is led to cooler 12 and then to separator 14 for removal of condensables, before being compressed to synthesis pressure in compressor 16 and thereafter divided into two branch streams by three way valve 18. One branch stream 19 is passed to washing tower 3 in which the gas is washed at ambient temperature with crude methanol taken from pressure separator 5, optionally by way of a decompression tank (113; see Fig. 2; not shown), by means of re-pressurising pump 21, and the washed gas is recombined at a suitable junction 23 with second branch stream before being passed, optionally in association with recycled gas, to synthesis reactor 4. The carbon dioxide-containing methanol which collects in the bottom of washing column 3 is passed through expansion valve 35 to decompression tank 6 before being transferred to distillation column 7 for recovery of the products.

Title: Improvements in the manufacture and production of conversion compounds of pyrene
IPC: C07C2/00
Filed: 1937-02-05
Abstract: Fats, oils, and waxes are coloured yellow and given a green fluorescence by incorporating a conversion product of pyrene made by contacting pyrene vapour with elements or their oxides favouring the splitting off of hydrogen at 400-1000 DEG  C.ALSO:Pyrene is contacted in the vapour phase with elements or their oxides which favour the splitting off at hydrogen at between 400 and 1000 DEG  C.  The products are yellow-red meals probably containing several pyrene radicles, and may be dissolved in hydrocarbons, fats, oils, and waxes giving a yellow colour and green fluorescence.  Suitable contact materials are bauxite, magnesium oxide, pure or coated with carbon, manganous or aluminium oxide, silica gel, or metals such as iron and copper. The vaporized pyrene may be led with a diluent gas such as nitrogen or carbon dioxide over the heated contact substance or passed through a heated iron or copper tube.  Unchanged pyrene in the products may be removed by heating under reduced pressure.  In examples, the contact material consists of: (1) pumice impregnated with manganous carbonate which is converted into oxide at 400 DEG C., treated with methanol, and heated to about 700 DEG  C.; (2) a copper tube at 810-830 DEG  C.

Abstract: 847,993. Flame desurfacing. UNION CARBIDE CORPORATION. Feb. 3, 1959 [Feb. 4, 1958], No. 3735/59. Class 83 (4). A flame desurfacing apparatus for curvedsection workpieces, particularly circular bars R, comprises an annular scarfing head H carried by a floating panel F mounted in a frame C, L, K for movement in two mutually perpendicular directions, the panel having a separate guide assembly 20, 55, Fig. 4, on each side of the head for maintaining the head coaxial with the workpiece. The panel F is slidable horizontally on axles which carry rollers 10 running in vertical guides 12 and is supported by a float cylinder 15 acting through linkage 14. On the input side of the head a pair of arms 20, 22 pivoted on the frame are movable by air cylinders 24 into a closed position whereby radially-adjustable tapered skids 36 carried on the arms provide guide surfaces for the workpiece. On the output side of the head pivoted guide skids 55 are actuated by air diaphragm chambers 56. The floating panel is initially centred by cylinders 18 controlled by a limit switch engaged by the workpiece, which cylinders are de-energized when the workpiece passes into the skids 36 which finally centre the panel. The latter is then locked in position by cylinder 27. After passing through scarfing head H, the workpiece engages the skids 55, Fig. 4, and the panel F is then unlocked. The head H has pre-heat orifices 46, 47, a main oxygen slot 43 fed by an orifice ring 50, and an adjuvant powder nozzle 49. Jets of water for removing slag are directed tangentially on the workpiece R by nozzles 65, 70, Fig. 5 (not shown), arranged in pairs.

Abstract: 610,730. Photographic roll-film cameras. KODAK, Ltd. Feb. 6, 1946, No. 3739. Convention date, Nov. 10, 1944. [Class 98 (i)] Means for rewinding film on to the supply spool in a roll-film camera having a oneway clutch associated with the film winding to prevent reverse winding and an exposure counter, includes a manually operable member, which, when actuated, moves the clutch and counter mechanism into inoperative positions and the rewinding knob into an operable position. As shown, the exposure counting mechanism consists of a slide 43 having a projection 44 engaged once per revolution of the feed sprocket 10 by a single-toothed gear 45 thereon, said engagement moving member 43 to the fight and causing spring arm 46 to engage one of the teeth of the counter disc 33 and thus rotate it one unit against the action of a flat spiral spring 32, which is prevented from rotating the disc by a pawl 38. When the full number of exposure frames has been wound off, as illustrated, further rotation of the winding knob will not affect the counter disc, thus indicating the fact to the operator who then slides the handle 29 to the left-hand end of the slot 30, thereby similarly moving the member 28 against the action of spring 31 and causing simultaneously (1) projection 49 to disengage the pawl 38 from the disc 33 which then returns to its rest position three teeth beyond that corresponding to the appearance of the first numeral in the window 35 to allow for winding on the leading portion of a new film; (2) projection 27 to engage arm 16 of a bell-crank lever pivoted at 17 on the casing, whereby rod 15 is caused to disengage the oneway pawl 12 from the ratchet-wheel 11 on the shaft 10 towards which it is urged by a spring 14; and (3) the other arm 18 of the bell-crank lever to move out of the notch 19 in the shaft engaging the supply spool, allowing the rewinding knob 22 to rise clear of the casing 23 under the influence of spring 24. Thus, by holding the handle 29 in its extreme left-hand position the film may be rewound on to the supply spool by rotating the knob 22.

Fixed-abutment type; back-pressure, reducing; driving pumps; packing drums and vanes.-A hollow radial vane 1 with a port 16 in one face is mounted on a hollow shaft 2 to sweep the concentric surface of a ported cylinder 5 and passes through an eccentric drum 6 having a vane slot 14 of greater length than the thickness of the vane. The cylinder is recessed at 7 to have surface contact with the drum 6 and a port 8 is formed in the cylinder adjacent thereto. The vane port 16 is so situated as to open to the cylinder space when the vane passes the cylinder port 8. To prevent back-pressure by fluid trapped in the cylinder or drum interior when the vane port 16 is no longer open thereto bye-passes 18, 17 are formed in the cylinder and on the vane boss. With elastic fluids the ports may be arranged to give compression or expansion. The drum 6 may be fitted with laminar springs 9 abutting against the vane to maintain the same against the proper edge of the slot 14. In the construction shown in Fig. 9 the drum 6 drives the vane and is formed with a groove 21 to allow delivery from the drum interior while passing the recessed part 7 of the cylinder. The drum may be formed with an end plate carrying a driving shaft or with teeth engaged by a driving pinion; the end plate which is provided with a renewable thrust ring may be chamfered at its periphery to receive a soft packing pressed thereto by a spring washer.
