Title: Process and apparatus for the removal of sulphur dioxide from flue gas
IPC: B01D53/81
Filed: 1975-03-03
Abstract: 1503692 Removal of SO 2  from flue gas SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 3 March 1975 [5 March 1974] 8684/75 Heading C1A SO 2  is removed from flue gas which also contains O 2  by passing the flue gas through a reactor at between 200‹ and 600‹ C. having separate inlet and outlet ducts for, respectively, flue gas and reducing gas, the ducts each being fitted with valves, and the reactor containing an acceptor of copper and/or copper oxide on a refractory carrier, until the acceptor is loaded with SO 2 , after which the acceptor is heated to between 200‹ and 600‹ C. to regenerate the acceptor material while simultaneously passing a reducing gas comprising H 2  and a diluent through the reactor. The flue gas at this stage is passed through a second reactor with a Cu/copper oxide containing acceptor. The process is characterized in that during regeneration of the loaded acceptor in the first reactor, the valves in the inlet and outlet ducts for the reducing gas of the first reactor are open, while the corresponding valves in the inlet and outlet ducts for the flue gas are closed, such that a stream of flue gas is passed through that part of the flue gas inlet and outlet ducts of this reactor located outside the closed flue gas valves as viewed from the reactor.

[Class 44.] A sliding-clasp fastener comprises two series of interlocking elements and each element is formed from a metal strip to provide two prongs 6, 7, adapted to pass through the stringer fabric and be bent over, and doubled portions 8, 9 forming a base to bear upon the face of the fabric. Each element is also provided with further doubled portions. In one series these portions 10, Fig. 3, are slotted at 11 for engagement with locking heads 19, Fig. 4, projecting from such doubled portions 17, 18, on the elements of the other series. The heads 19 are also formed by doubling the strip and have reduced necks 20. The doubled portions are flat and lie adjacent and in alignment when the elements are interlocked. In action the heads 19 engage in the slots 11 and are retained therein by the adjacent heads 10 which form in effect a series of transverse bars 21, Fig. 2, such that the heads 19 may not be withdrawn unless the elements are inclined at an angle as at 30. The doubled portions form continuous ribs so that the slider engages between the portions 8, 9 and either the portions 17, 18 or the portion 10. The slider may comprise two plates joined by pins, grooves being formed by a triangular projection on one plate. The device may be applied for fastening overlapping pieces of material and be such that the elements be wholly between the fabric surfaces and are thus entirely concealed.

[Also in Group XXXI] Three nested U-shaped striker forks 54, 92, 70 have aligned holes in their limbs by which they are mounted upon guide rods 50, 51, a depending finger 128 on a gear shift lever 123 selectively engaging one or other of three notches 55, 95, 72 in the upper surfaces of the forks so that each striker can be slidden independently of the others to establish a ratio in a five-speed and reverse change-mesh changespeed gear. The lower surface of each striker is provided with three notches, such as the notches 150 ... 152, Fig. 6, in the lower surface of the striker 54, for engagement by a spring-biased plunger 153 to hold it in either of its two engaged positions or in its central, neutral position. A separate plunger 153, Fig. 14, is provided for each striker fork, and each plunger has a reduced neck 166. A disc 167 is arranged between the three necks 166 and is so proportioned that when one of the plungers 153 is depressed during a ratio shift, the disc is displaced sideways and locks the other two plungers in position, thereby preventing movement of the associated two striker forks. The striker forks control the axial positions of gears 30 ... 34, Figs. 1, 2, slidable upon a driven shaft 29 connected through a bevel gear differential 40 to the road wheels of a tractor. The gears 30 ... 34 mesh selectively with associated gears 22 ... 26 fast on a driving shaft 20 and with a reversing idler 35.
