Abstract: There is disclosed an improved method for the purifi­cation of H₂S containing gases, which comprises the steps of (1) oxidizing a solution of ferrous sulfate into a solution of ferric sulfate with the aid of an iron-oxidizing bacte­rium; (2) absorbing the H₂S in the gas by the solution of ferric sulfate by bringing the gas into contact with the solution; (3) separating and recovering the elemental sulfur produced in the solution during the second step; and (4) returning the solution of ferrous sulfate, which is obtained in the third step in an elemental sulfur free state, to the first step to be oxidized again into a solution of ferric sulfate; said method also comprises that the oxida­tion in the first step is carried out in a fixed-bed type oxidation vessel which is filled with a bacterium support onto which an iron-oxidizing bacterium has been deposited.

Abstract: In a beam shaper superpositions of a deformed first diaphragm and a deformed or non-deformed second diaphragm can be realised by means of a quadrupole system. As a result of this a great freedom for adapting the spot cross-section to the patterns to be formed is obtained, as a result of which the number of writing pulses per pattern and hence the writing time for, for example, a chip can be considerably reduced and in particular non-­orthogonal and non-linear transistions in the patterns can be written with greater definition.

Abstract: In a known method of making spring units for use in mattresses, etc., a plurality of spring bands (7, 8, 9) are disposed side by side and linked together by transverse helical wires (6A, 6B) to form a length of spring unit which is subsequently divided transversely to form individual units. Each spring band is made from a length of wire bent to form a row of coil springs (1), each of which is integrally connected to the next by a connector (2). Each connector has spaced end portions (3) extending transversely of the band and an intermediate portion (4) extending past the two springs it interconnects. The helical wires (6A, 6B) lie in main faces of the unit and embrace the end portions (3). In effecting division, a helical wire is omitted or removed from one main face, and the adjacent connectors in the other main face are severed. To enable the severed connectors to be attached to a peripheral frame (11; 116), the intermediate portions (4) to be severed are first to provide transversely extending central parts (109) which are shaped and severed to provide attachment portions (113) provided with stops (114) to prevent detachme.nt from the frame.

Abstract: Problems are caused by stress corrosion cracking and exfoliation cracking in the heat-affected zones adjacent welds in structure of welded components formed of Al alloys, particularly of the 7000 series but also of the 5000 series. The invention seeks to overcome these by the use of Al-Mg welding wire containing 0.01-0.5% Ga and/or In and/or Sn, the composition being chosen such that the weld bead has a potential at least as electronegative as the components and preferably in the range -1200 to -1300 mV with reference to a standard calomel electrode. To prevent diffusion of Ga/In/Sn, the components may be pre-coated eg by using a double-pass welding technique.

Abstract: This slide element (1) has a profiled slide surface (2). In order to provide good slide characteristics, which remain constant over a long period, in a cost-effective manner in year-round operation, it being possible for the slide element to be assembled without problems on known understructures and said slide element entailing low maintenance expenditure, the slide element (1) is constructed as a single-piece, self-supporting body, on the slide surface (2) of which convexly designed slide segments (3) are arranged, which consist of a paste. The process for producing said slide element is distinguished by the fact that, after the shaping of the body of the slide element (1) in a predetermined grid, drops consisting of paste are applied to the slide surface (2), forming the convexly designed slide segments (3), and allowed to dry on. Subsequently, the entire slide surface (2), including the slide segments, are covered with a paste and the slide element is then baked. <IMAGE>

Abstract: A device and method for winding conical bobbins (24) with yarn withdrawn at constant speed from individual spinning units, and comprising a deflecting roller, peg, or similar element (5), which is connected to and moved backwards and forwards by a swinging arm (4) which by storing and returning the yarn with swing movement compensates for the different speeds at which the yarn is collected on the conical surface of the bobbin (24) under formation. Said deflecting roller (5) varies the length of the yarn path so as to stabilise the tension of the winding yarn being deposited at a practically constant value during the entire cycle defined by the travel of the yarn guide element from a position corresponding to one end of the bobbin to its return into said position. 
     The value at which the tension of the yarn is stabilised during its winding onto the conical surface derives from the elastic action generated by a spring (6) or similar element. The position of the deflecting roller is determined at every moment by an analog or digital transducer (7, 36). 
     The value of said store must fluctuate within a range extending   between preset limits. If a storage value arises which does not lie within the preset range, the transducer generates an output signal the intensity of which is such as to activate, by means of a central unit (8), a drive source (9) which is arranged to vary the extent of elastic deformation impressed on the spring (6) or like elastic element. Said variation corrects the tension of the yarn being wound to a value which is slightly different from the preceding value so as to rapidly return the fluctuating storage to within the preset range.

The method includes the steps of lowering a casing patch tool to position the annular member (16) to which the upper end of the casing (10) is to be connected and a casing protection collar (24) both in surrounding relationship to the upper end of the casing and with the cold forging tool (36) and the tensioning spear (34) within the casing, setting the spear within the casing at a level surrounded by the casing protection collar, pulling on the spear to tension the casing, and cold forging the casing into tight gripping and sealing engagement with the annular member. The apparatus includes the annular member (16) to which the casing (10) is to be connected, a guide sleeve (20) on the lower end of the annular member (16) sized to be lowered in the well bore and into surrounding relation to the upper end of the casing, a cold forging tool (36), a spear (34) and a protection collar (24) positioned within said annular member at the level of the spear so that it surrounds the casing to prevent excessive deformation on setting and tensioning by the spear. It is also a part of this invention to provide an improved method and apparatus for tensioning the casing and protecting it from excessive deformation as a result of the setting and tensioning of the spear by surrounding its exterior in the area of spear engagement with a protection collar which has sufficient strength and is sufficiently close around the casing to provide such protection.
