Title: Improvements in or relating to process and apparatus for elevating contact material from an engager to a disengager in catalytic conversion of hydrocarbons
Inventor: THAYER CLARENCE HERBERT
IPC: B01J8/00
Filed: 1952-06-24
Abstract: <PICT:0716832/III/1> <PICT:0716832/III/2> <PICT:0716832/III/3> In apparatus for cracking hydrocarbons of the kind in which granular or pelleted contact material or catalyst is raised pneumatically from a lower receptacle which receives the material in a continuous stream, to an upper receptacle, a zone of material is maintained adjacent the inlet of each lift conduit and a stream of conveying fluid is directed to the lower end of the zone of material, a substantially constant rate and velocity of flow of material into the conduit being maintained by varying the depth of material in the zone in accordance with any variation of pressure within the conduit.  A series of conduits 21, Fig. 2, only one of which is shown, enters the receptacle 10 and their inlet ends 23 depend into and are spaced apart from sleeves 22 which pass through and are welded to the wall of the receptacle. Material passes into the space between each sleeve and its associated conduit.  A nozzle 29 in the lower part of each sleeve is supported by a rod 32 attached to a piston P working in a cylinder 35 to which pressure fluid can be admitted for raising and lowering the nozzle.  The sleeve is divided by a plate 25 into a chamber C for contact material and a chamber F for the lifting fluid which is admitted by a pipe 28 to the space between the plate 25 and an apertured guide ring 26.  A line 40, Fig. 3, connects the conduit 21 to a remote-control pressure transmitter 41 to which air used for the control of the various instruments is supplied by a pipe 42.  A pipe 43 connects the transmitter 41 to a pressure controller 44 which is connected by a pipe 46 to the controller 45 of the piston P.  The supply of lifting medium through the pipe 28 is controlled by an orifice plate O positioned between flanges 51, 52.  Pipes 53, 54 lead from points in the pipe above and below the plate to a manometer M which is enclosed in a flow-transmitting cylinder 55.  Air is supplied to this cylinder through pipes 56, 57 and, in accordance with the differential pressure across the plate O is transmitted by the pipe 58 to a flow and recording cylinder 59 from which it passes through the pipe 60 to a valve 61 controlling the supply of pressure fluid through the pipe 28.  The upper ends 70, Fig. 6, of the conduits 21 are flared and open into a chamber 15.  The pipes 70 are separated by vertical partitions 72 secured to a central post 71. A transverse plate 73 is suspended from the top of the chamber above the upper ends of the post and partitions.

Abstract: 262,044. Brown, E. Nov. 28. 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Regulating. - In two-stroke engines having exhaust and scavenging-air ports uncovered successively by the piston, increase of the air charge retained in the cylinder during compression for increasing the output of the engine is obtained by increasing the back-pressure of the exhaust, and in one form the backpressure may be varied by adjustment of an exhaust-driven turbine which drives the scavenging-air fan. Fig. 12 indicates a turbine in which the exhaust gases pass through a cage 68 carrying the guide blades or nozzles, and flow thence into an exhaust pipe 70, driving the bladed rotor 69 which is connected to the fan. The variation of back-pressure is obtained by adjusting the overlap 72 of the guide and rotor blades by means of the rod 73.

Filed: 1949-06-24
Abstract: 678,376. Invertible ploughs. GRANGES, L. June 24, 1949 [Feb. 24, 1949], No. 16850/49. Class 6(i) In a tractor-mounted invertible plough the inversion is effected automatically as the result of lifting the plough bodily by the tractor. The plough comprises a hollow triangular casing 1, the lower tractor lift-links 3, 4 being pivoted to two of its apices and the upper link 46 being pivoted to a standard 45 mounted on the casing. A longitudinal beam 9 is rotatable in bearings 7, 8 in the casing and carries a cylindrical plate 15 near its mid-point. A hollow tool-carrier 11 is supported by a ball 10 on the end of the beam engaging an internal seating 10a. A matching cylindrical plate 13 on the perch is adjustably bolted to the plate 15 so that the tools may be angled slightly to the line of draught. During inversion, the beam 9 and carrier 11 swing together in the bearings 7, 8 under the action of a spiral spring 17 which is biassed to resist the motion at the end of the cycle, thus reducing inertia. A dashpot (not shown) may also assist the damping. As the plough is raised, a hook 43 engages an abutment 44 on the tractor. The hook is carried by a bracket 33 slidable along a vertical post 34 on the casing 1. The sliding of the bracket pulls back a bolt 24 locking the tools in position, the unlocking being effected by a pivoted lever 30 connected to the bracket 33. A second pivoted lever 37 carrying a roller 38 engages a cam 39 on the end of the beam 9 and forces the beam to rotate. The bolt 24 alternately engages stops 21, 21a secured to the plate 15, these stops being adjustable to vary the operating position of the tools around the longitudinal axis. Other tubular perches carrying different tools may be substituted for the perch 11. Specification 544,041 is referred to.
