Title: Process for reducing sulphur content of effluent gas streams
Inventor: BEAVON DAVID KENT
IPC: B01D53/50
Filed: 1971-01-12
Abstract: 1344471 Reducing sulphur content of effluent gases RALPH M PARSONS CO 12 Jan 1971 [12 Jan 1970] 1381/71 Heading C1A A continuous process for reducing the sulphur content of an effluent gas stream comprises (a) enriching the effluent with a source of hydrogen to a level at least equal to the stoichiometric amount required to convert SO 2  and free sulphur in the effluent gas stream to H 2 S, (b) catalytically hydrogenating the enriched gas stream at 300‹ to 1200‹ F. to convert the SO 2  and free sulphur to H 2 S, (c) removing at least some of the water present in the hydrogenated gas stream and (d) then recovering the H 2 S by subjecting the hydrogenated gas stream to gas phase oxidation to convert the H 2 S to free sulphur. If the gas stream contains COS or CS 2  these are hydrolysed to H 2 S with water present in the stream during step (b). The hydrogenation may be effected using a supported or unsupported rare earth metal or a metal of Groups Va, VIa or VIII of the Mendeleef Periodic Table. The gas stream may be enriched with molecular hydrogen or with a donor material, e.g. CO which reacts with water to yield hydrogen. Step (c) may comprise condensing water from the gaseous stream below 120‹ F. then contacting the stream with a desiccant, e.g. silica gel or a glycol. Divisional Specification 1,344,472 is referred to.

Title: Article dispensing mechanism
IPC: G07F11/24
Filed: 1963-01-11
Abstract: 985,835. Dispensing bottles. WESTINGHOUSE ELECTRIC CORPORATION. Jan. 11, 1963 [Feb. 14, 1962], No. 1390/63. Heading B8S. [Also in Division G4] Bottles which are supported in two adjacent parallel overlapping stacks in magazine 12 are released one by one by the the movement of discharge rods 21 and 22. Thus rods 21 and 22 are carried by pairs of levers 23 and 25 which pivot about points 24 and 26. Thus levers 23 are caused to pivot anticlockwise about pivot 24 from the position shown in Fig. 1 to the position shown in Fig. 2. This causes rod 21 to move rightwards and to release the first bottle A for discharge. Levers 23 are then caused to pivot clockwise into their original position, and the apparatus is then ready for the subsequent charge of bottle B by the similar movement of rod 22. Thus each column in turn has its lowermost bottle released. General operation (Figs. 6 and 7). The levers 23 and 25 carry respective followers 31 and 32 which move in slots 34 carried by respective sliders 28 and 29, so that vertical movement of the sliders actuates the levers 23 and 25 and thus causes the pivotal movement of rods 21 and 22. The vertical movement of sliders 28 and 29 is derived from the movement of carriage 43 which is moved up and down by the oscillation of driving shaft 70. Carriage 43 is coupled to each slider by a lifter 51 pivoted at 53 and engaging at 54 in a slot in the slider. Lifter 51 is moved into the slot by the engagement of a respective cam 57, the two cams 57 being operated by a single solenoid 61 via rod 67, pawl 68 and ratchet wheel 63. Solenoid 61 causes a step-by-step turning movement of shaft 58 so that in turn each of the two cams 57 engages its respective lifter 51 to cause the latter to engage at 54 with its respective slider 28 or 29. Thus as carriage 43 moves upwards solenoid 61 causes by means of the first cam 57, the first lifter 51 to engage slider 28, to cause the pivotal movement of rod 21 to release a bottle. On the next upward movement of carriage 43 the solenoid causes by means of the second cam 57 the second lifter 51 to move into the slot of slider 29, thus causing the pivotal movement of rod 22 to release the bottle from the other column. The apparatus is now ready for a repeat operation of the cycle.

Abstract: 262,698. Cox, F. B. Oct. 19, 1925. Automatic circuit-breakers; springs, arrangement and disposition of. - In electric switches with primary and secondary members carrying or actuating movable switch contacts and mounted on a common axis or an adjacent axis and connected together by a spring, the primary member is provided with a second spring strong enough to overcome the pull of the connecting spring, the arrangement being such that, when the primary member is moved in one direction to close a set of contacts in the circuit, it engages and moves the secondary member into a position to close a second set of contacts and the secondary member is held by an'automatically-controlled device, the primary member when released being then moved by its spring in the opposite direction into its second position to open the first set of contacts and closing a third set of contacts and the connecting spring being thus stressed to be able to move the secondary member to open the second set of contacts when it is released by its automatic device. The arrangement is described as applied to a motor starter of the star-delta type, shown in Fig. 1, and when modified as a circuitbreaker, shown in Fig. 3<A>, for contacts to be connected in series. When the primary member A, Fig. 1, is moved anti-clockwise to make contact with D<1> and close the starting connections of the motor, its abutment a<3> moves the secondary member B to close the circuit contacts E provided with an electromagnetic retaining device F. On the release of the member A, it is drawn by its spring a' into contact with D<2> to give the running connections. At the same time the connecting spring S is stressed so that, should the supply fail or should there be an overload, the device F is operated to release the arm B, which is moved against the stop b<2> to break the motor circuit. In a modification, the member A is operated by a loose handle mounted on the same pivot axis and arranged to release a detent engaging an extension of the primary member when the handle is returned by the spring a'. In the circuit-breaker shown in Fig. 3A, the contacts E, D are connected in series. When the detent F is released, the member B is moved against the stop b<2> by the stretched spring S to break the circuit. For three-phase circuits three pairs of contacts are used, closed by insulating bridging-pieces carried by the respective members.

Tantalum powder with a particle size between 5 and 30 microns and an uncompacted density of 5.5 gms./c.c. is poured into a mould made preferably of tantalum and the loose powder is sintered at a pressure between 5X10-3 and 12X10-3 microns Hg abs. at 2150  DEG C. for half an hour.  The sintered porous compact has a density below 10 gms./c.c. and a dielectric oxide film is formed on the compact by anodic oxidation in a 0.01% phosphonic acid solution at 90  DEG C.  A tantalum lead wire may be inserted into the loose powder before sintering and if necessary the loose powder may be lightly tamped to secure the lead wire in position. In a modified method the loose powder is first presintered in vacuum, the presintered compact is removed from the mould and then sintered.
