Abstract: 1,220,052. Pipe-cutters. MERCOL DESCALING CO. Ltd. 18 April, 1968 [23 Jan., 1967], No. 3297/67. Heading B3W. A pipe-cutter comprises cutter discs 10 '  pivotally interconnected by pairs of links 38, and pairs of levers 12, 14, each pivotally connected at one end to spaced points on the cutter-disc assembly. The other ends of the levers 12, 14 are pivotally connected to opposite ends of an hydraulic ram 22 which has opposed pistons 24, 26 working in a common cylinder 28. Sandwiched between the levers of each pair and pivotally connected to them by pivot pins 18 and 20 are the respective ends of a bar 16. Each pair of levers is retained on its respective pivot pin by a split pin 40, Fig. 2 (not shown), which also serves to retain the levers on the pivot of a cutter disc and on the ram pivots 34 or 36. To remove a pair of levers from one cutter disc pivot to vary the effective length of the cutterdisc assembly, the split pin 40 is removed, one lever 12 is withdrawn from the cutter disc pivot and the pair of levers is re-engaged with the selected one of the other discs. A dowel 42 passing through both levers 14 and the bar 16 prevent their relative pivotal movement. In an alternative method of disengaging a lever 12 from a disc pivot, the pivot pin 18 has an extension on to which the lever 12 may be slid to withdraw it from the cutter disc pivot. There is a split pin adjacent the free end of the extension and another split pin on the pivot pin 20. In a further embodiment, there is a split pin at each end of each pivot pin 18 and 20. Instead of split pins circlips may be used to retain the pairs of levers on their respective pivot pins 18, 20. The opposed pistons may be replaced by a single piston acting in a cylinder closed at one end and the discs may be replaced by non-rotatable straight edged cutters.

The numerals relate to Fig. 1 which illustrates preferred features including the use of a baffle 32 to prevent erosion of the perforated grate, a draft tube 30 having a diameter 0.4 to 0.9 that of the reactor and a height less than one-third that of the reactor or about 0.1 to 0.4 that of the fluidized bed.  When used for hydroforming, preheated naphtha is passed into the apparatus through line 23 which terminates in an enlarged section 231.  Recycle gas rich in hydrogen enters through line 25 terminating in enlarged portion 251 concentric with 231 and substantially flush with the lower wall of the reactor.  The rising mixture passes through circular grid 31 which may if desired be slightly concave upwardly. The particles pass into the upper part of the reactor and then descend for recirculation round the outside of the draft tube 30. The diameter and height of the draft tube may be selected to provide a pressure drop of 1 to 10 inches of water across the upper and lower boundaries thereof.  Spent particles are removed through inlets 14 into stripper 15 having baffles 16 and thence through line 21 to a regenerator.  The regenerated catalyst is returned to the reactor through line 12.  For hydroforming processes the Specification refers specifically to catalysts containing 0.2-2.0 weight per cent platinum on alcholate alumina and to a carrier supporting 5 to 15 weight per cent of molybdenum oxide or 10 to 40 weight per cent of chromium oxide; to the presence of minor amounts of stabilizers and promoters such as silica, calcium oxide, ceria, or potassia; and to particles of 0-200 microns of which a major part are from 20 to 80 microns. The invention is also stated to be applicable to the catalytic cracking of hydrocarbon oils introduced through section 231, using a silica-aluminium catalyst, in the presence of steam introduced through 251.
