Title: Process for the removal of sulphur compounds from claus off-gases
IPC: C01B17/04
Filed: 1974-08-06
Abstract: 1480228 Disulphurizing Claus off-gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 6 Aug 1974 [8 Aug 1973 34569/74 Heading C1A [Also in Division G3] In a process for treating the off-gases from a Claus process to remove SO 2  and other sulphur compounds by mixing them with reducing gases containing H 2  and/or CO, passing them at a temperature of 175‹ C. over a sulphided Group VIa/Group VIII metal catalyst (Mendeleev table) supported on an inorganic oxide carrier, cooling the resulting gases, at least partially by direct cooling with an aqueous liquid, to a temperature below the dew point of water and subsequently converting the resulting H 2 S to elemental sulphur; the supply of reducing gases containing H 2  and/or CO required to reduce the sulphur dioxide is controlled by (1) either (a) measuring the H 2  present before or after the direct cooling or (b) the amount of elemental sulphur in the cooling liquid after direct cooling, (2) generating a signal proportional to the H 2  or sulphur measured and (3) using the signal resulting from this measurement to adjust the supply of reducing gases. The hydrogen sulphide present in the treated gases is converted into sulphur by passing the cooled gases through a liquid and regenerable absorbent, regenerating the H 2 S- enriched absorbent and supplying the H 2 S- rich mixture liberated in the regeneration to a Claus plant.

Abstract: 414,690. Metalworking presses. HUMPHRIS, F., Park House, Park Road, Parkstone, Dorset. Dec. 7, 1932, No. 34618. [Class 83 (iv).] In a press &c. having a ram operated through a toggle linkage and adjustable by threaded elements associated with the bridge of the press, a threaded rod a supported in an aperture in a bridge piece d by an internally threaded collar b is clamped and locked in its adjusted position by a spring controlled device which as shown consists of a two part ring a<2> apertured near its periphery to receive screws a<4>, Fig. 9, which hold springs a<3> under compression against the collar b to prevent rotation thereof. A second ring a<2> engages the underside of the bridge d. The rod a may be rotatable in threads formed directly in the bridge d or in a bush therein or the bush may be rotatable and the rod be held against rotation. At its lower end, the rod a is either integral with or secured to a crosshead c guided in the press frame A by a bolt c<2> passing through the crosshead and slots in the frame and edge plates h, h<1> at the ends of the crosshead constitute the toggle linkage. For a wider ram, two or more threaded rods a, Fig. 5, are secured to a crosshead c and pass through rotatable bushes b to which they are clamped by a ring a<2> after adjustment. The bushes b are geared together for simultaneous movement and are supported by a grooved two part collar e provided with adjusting screws f<1> engaging a revolvable ring f on the bridge d.

Title: Non-efflorescent latex compositions and method of making the same
IPC: C09D109/08
Filed: 1953-12-11
Abstract: A non-efflorescent coating composition is formed by making an aqueous dispersion of a copolymer of polymerizable unsaturated organic compounds including at least 15 mol. per cent of a monovinyl aromatic hydrocarbon of the benzene series and between 40 and 60 mol. per cent of butadiene or isoprene, in an alkaline aqueous solution of ionizable alkali compounds which alkali compounds in the solution yield potassium, sodium and sulphate ions and contain a total of at least three parts of potassium per part of sodium, the total of alkali ions chemically contained in the ionizable compounds being from 0.35 to 1 per cent of the combined weight of the alkali compounds and the copolymer. Specified monovinyl aromatic hydrocarbons are styrene, vinyl toluene, and nuclear ethyl styrene, while vinyl or vinylidene chloride may be present as a third monomer. The composition may be prepared by dispersing the monomers in an alkaline aqueous medium containing an emulsifying agent, a catalyst, and an alkaline pH buffering agent and comprising the ionizable alkali compounds and then polymerizing.  Specified emulsifying agents are the soluble salts of oleic or other soap-forming fatty acid, the soluble salts of lauryl sulphate or other sulphated higher molecular weight alcohols, soluble salts of sulphated fatty glycerides, and soluble salts of sulphonated alkylated naphthalene or other sulphonated alkyl-aromatic hydrocarbons; specified catalysts are hydrogen peroxide, organic peroxides or hydroperoxides and potassium, sodium or ammonium persulphate; while specified buffering agents are potassium bicarbonate, other soluble bicarbonates or carbonates, alkali metal hydroxides, alkali metal salts of weak acids, ammonia, amines, hydroxyalkylamines and quaternary ammonium hydroxides.  A number of inorganic or organic water-soluble ionizable compounds of potassium are listed.  The potassium salt may also be added to the performed coating composition.  Pigments such as lithopone, mica and titanium oxide may be present.

Class 20(3) A draught excluder for the bottom of a door comprises two members preferably cylindrical as 20, Fig. 2 or 40 Fig: 4, or arcuate as 30, Fig. 3, connected or connectable together by separate resilient means which can pass underneath the door to hold said members in position against the bottom of the door and floor and to move along the floor as the door moves. The members 20, 30 or 40 may be adjustable relatively axially to accommodate doors of different widths. Elastic bands 21 pass around the solid members 20 preferably located in grooves 22. Elastic strips 31 are held as by knotted ends in holes 32 longitudinally spaced in the arcuate members 30. The arcuate members may be replaced by tubular members and the series of holes replaced by a longitudinal slit. (Fig. 1, not shown). The members 40, may be solid or tubular and have a longitudinal U-shaped recess 42 accommodating a rigid bar 44 which retains a wide rubberized elastic continuous band 41 passing through the recess. The bar 44 is secured at one end in the end 48 and at the other end in a hole 47 in a protuberance 46 in a removable end cap 45, the protuberance entering the recess 42. The end 48 may also be a cap permanently attached to the member 40. In a modification the ends of the bar 44 bent twice at right angles are secured at the centre of the end faces of the member and this latter, without the recess 42 can rotate on the bent ends as the door moves.

Abstract: 411,899. Chucks. CONE, F. L., 129, State Street, Windsor, Vermont, U.S.A. Dec. 14, 1932, No. 35478. [Class 83 (iii).] Work-holding and feeding means for use with automatic multiple spindle lathes and like machines comprises a hollow work spindle, a collet and co-operating hood and an element movable in one direction to force the collet and hood into workgripping engagement, the reverse movement of the element operating positive means to permit the collet to release the work. The collet sleeve 32 passes through the hollow spindle 35, rotated by gears 75, 76, and terminates in a collar 39 which abuts the sleeve 40 carrying the collet-operating arms 42. Movement to the left of a cam-faced collar 45, operated by a yoke 56, rotates the arms 42, which engage the wear-piece 49 on the end of the spindle, and the sleeve 40 is displaced to the left thus closing the collet. Movement of the collar 45 to the right results in the arms 42 being released and further the coming into operation of the lost-motion bolts 50 the heads of which finally engage the base of the sockets 52 and positively draw to the right the sleeve 40, thus permitting release of the work. The reciprocating gripper 31 for feeding the stock passes inside the collet sleeve and is actuated at the head 65 by means not shown.

To eliminate machining errors in the markings of a scale, an adjustable optical element is provided for each scale marking whereby any desired image-shift may be effected. As shown in Figs. 1 and 3, a supporting device 4 has apertures opposite each scale-marking 2 provided with a rotatable mount 5 carrying an inclined glass plate 6. This causes lateral displacement of the iimage of marking 2, the locus of the displaced image position being a circle as the mount 5 is rotated. The support 4 rests firmly in the H-sectioned body 1 of the scale, an inclined cover-glass 8 being provided to eliminate disturbing reflections. Errors in the intersections A-E of a grid-scale (Fig. 5), may be similarly corrected, using two glass plates. It is useful to employ mounts for the inclined glass plates that, as shown in Fig. 9, can be tilted about a horizontal axis X by means of screws 34, 35 and the knifeedge 33, as well as rotated about a vertical axis. A scale having correctly-adjusted optical elements can be used as a master in a comparator apparatus.
