Patent GB-1037942-A (GB)
Title: Desulphurlsation of gases
IPC: B01D53/48
Filed: 1963-02-07
Abstract: A method of removing organically or inorganically combined sulphur from a gas containing CO and/or H2 and/or a hydrocarbon, comprises adjusting the dew point to at least 15 DEG  C. by adding water or steam and oxidizing the sulphur compounds between 300-600 DEG  C. in the presence of an alkaline earth metal compound which is effective to absorb or combine with sulphur oxides under the conditions employed during the oxidation. Oxides, hydroxides and carbonates of Mg, Sr, Ba and preferably of Ca, alone or in mixtures of two or more are mentioned, and alkali metal compounds, preferably of K or Na, may be added as activators. Carrier materials mentioned are synthetic Al silicates, Al oxides, and diatomaceous earth, e.g. kieselguhr. Oxygen present in the gas may be relied on for oxidation, or air may be added, and if the alkaline earth metal compound is in two stages in series, air may be added before each stage, the oxygen content by volume of the gas being raised to 1%.  A pressure range of 0.5 to 50 atmospheres is mentioned for the oxidation reaction, and gases referred to include coke oven gas, water gas and producer gas.  If the gas is predominantly hydrocarbon, organic sulphur compounds may be catalytically converted to H2S before the main purification step, e.g. with Co-Mo, Co-W, Ni-Mo, NiS catalysts.  Fixed or fluidized beds may be employed for the alkaline compounds, and the steam and water added to the gas may increase the volume proportion of water vapour to gas to 1:1 or even 2:1.  A comparative example is described.

Abstract: 947,387. Boring earth &c. BORG-WARNER CORPORATION. Feb. 15, 1960 [Feb. 25, 1959], No. 5317/60. Heading E1F. In a well pipe elevator having slips in a tapered bowl, slip setting means are disposed above the slips and are engageable with an enlargement on the pipe to impose the weight of the pipe on the slips, the said means comprising a plate which is operatively engaged with the slips to shift them longitudinally whilst permitting radial movement of the slips relatively thereto. The slips 7 are arranged in pairs in each of two hinged and latched bowl members 2 having guide rods 10 and release springs 12 for the slips, which are connected together by a projection on each slip engaging in a hole in the adjacent slip. One pair of slips is provided with a slip setting plate 21 with an anti-friction ball 33 arranged and retained in recess 34 at each of diametrically opposite points relatively to the pipe 20. The upset portion 18 of the pipe acts on the balls to depress the plate 21 and, through a resilient pad 26 and plate 23, one pad and plate 23 for each slip, depresses the slips in the bowl, inward movement of the slips being permitted by the clearance holes 30. The plate 21 has dowels projecting downwardly into holes in the pads 26 which are thus distorted as the slips move inwardly and assist in retracting the slips. In a modification, the balls 33 are replaced by rollers housed in slots on the diametral line, and journalled on horizontal pins. Alternatively, the contact between the diametral points on the plate 21 and the upset 18 may be by arcuate protuberances faced with hardened material surfaces. The hard face member may be reversible when one face is worn. The pads 26 may be dispensed with and cylindrical buffers arranged around the bolts 29, or the cylindrical buffers and the pads may both be used. Two substantially half-annular slip setting plates 21 may be used, one for each pair of slips.

Abstract: 470,927. Alternating-current generators ; supply systems for welding-arcs. SIEMENS - SCHUCKERTWERKE AKT.- GES. Feb. 24, 1936, Nos. 5549 and 5550. Convention dates, Feb. 23, 1935 and April 5, 1935. [Classes 35 and 38 (iv)] Weak excitation at no load of an alternating-current arc welding generator is obtained by exciting it directly or indirectly through a current transformer and static rectifier so that the excitation increases with generator current or where the generator is driven by a continuous-current motor the generator is excited in proportion to the motor load current. In the form shown in Fig. 2, the generator exciting winding 3 is energized by an exciter 4 having a shunt winding and a field winding 14 energized in proportion to the generator current through a transformer 13 and rectifier 8. The shunt winding of the exciter may be omitted. Instead of being on the exciter, the winding 14 may be on the main generator 2, with or without a generator field winding fed by a separate exciter. In another form, the current transformer and rectifier are in series with the exciter field winding. Instead of the current transformer being in the main generator circuit it may be in series with an alternating-current motor driving the generator. In the form shown in Fig. 16, the exciter field winding is connected across a shunt 35 used instead of a current transformer and rectifier when a direct current motor is available for driving the generator. The generator may be of the inductor type, and may have a conductive cylinder on the rotor to serve as a damper.
