The arms 50, 51 are acted on similarly by the unit 110 at the same time. The sequence of tape applying operations is indicated in Figs. 6a, 6b, 6c (not shown).
Patent GB-791154-A (GB)
Title: Process and apparatus for transfer of fluidized solids
IPC: B01J8/24
Filed: 1954-12-14
Abstract: <PICT:0791154/III/1> In a process in which fluidized solids, usually up to 1000m  in size, are transferred between two vessels, such as a reaction vessel and a regeneration vessel, the transfer is achieved by altering the pressure in one vessel so that the solid is transferred by reason of a pressure differential.  Thus reaction vessels 10, 12 are connected by means of the pipe 40 for the flow of fluidized solids.  Pressure controlling means 29 and timing means 33 actuating pressure control means 29 periodically changes the direction of the pressure differential between the two vessels by actuating valves 20 and 28.  The reactor may be inside the regenerator or vice versa.  The invention may be used in processes such as catalytic conversion of hydrocarbons, cracking and reforming of petroleum hydrocarbons, the hydro-desulphurization of heavy residual petroleum oils, hydrogenation process, the coking of coals and residual oils, and the manufacture of gas. Exemplified is the hydro-desulphurization of 17 to 20 per cent bottoms of Kuwait crude oil in a reactor with hydrogen at a temperature of 750 DEG  to 950 DEG  C. and at a pressure of 250 to 2500 p.s.i.  The pressure in the regenerator for the catalyst is maintained at the same level as the reaction pressure until the catalyst is to be transferred when it is decreased.

A brake mechanism comprises a shoe 12, a drum 10, a backing plate 11, a torque-resisting member 40, an anchor 49 on the member 40 adjustable by a pawl 60 but normally locked by a spring 80, a linkage 67-71-73 activated by application of the brake (when applied with the drum moving in reverse) to move the pawl 60 to an operative position, an end portion 84 of the spring 80 being engaged in an aperture 85 in the web 18 of the brake shoe so that the spring 80 is moved out of engagement with the anchor 49 if the brake moves more than a predetermined distance outwards due to excessive wear, Fig. 2, which shows the shoe 14 being applied to the drum which is turning in the reverse direction A, illustrates half of a two-shoe brake of which the other side is similar but inverted when the brake is applied to the drum moving in the direction C and without an adjustable anchor on the member 40. The shoes are held movably to the back plate 11 at 30 and return springs 24 hold the ends of their webs 18 against the adjustable anchors 49 at one end and against fixed anchor surfaces on the torque members 40 at the other. One of the latter anchor surfaces and its mating shoe edge are shown as the two rearradial dotted lines near the bottom of Fig. 2, where the shoe has moved out to contact the drum 10 which is moving in the direction of the arrow A. The brakes are applied by hydraulic cylinders 20 interposed between the ends of the shoes. A light spring separates opposed pistons (Fig. 1, not shown), which have plungers 23 at either end at 20. The anchor 49 is adjustable for length due to its threaded shank screwed into the torque member 40. Its head 51 has circumferential teeth 52 and a knurled front face (Figs. 4 and 5) which is normally engaged by a nose 83 of the locking spring 80 to prevent turning. The pawl 60 is pivoted at 62 on the web 18 and is urged to engage the teeth 52 by a spring 64. The linkage 67-71-73 has one end fixed to the back plate at 74 and its other end 68 hooked into a slot 69 in the pawl 60. The slot 69 is elongated to provide lostmotion so that the linkage does not cock the pawl 60 against the spring 64 unless the outward movement of the shoe, when applied to the drum moving in the reverse direction A, exceeds the predetermined distance. On release of the brake the pawl re-engages the teeth 52 but does not turn the anchor 49 as it is already engaged by the nose 83 of the locking spring. If the brake is applied when the drum is moving in the forward direction the linkage does not cock the pawl 60 but the shoe is withdrawn from the anchor 49 which is thereby released from the locking member so that the pawl is free to turn the head of the anchor to move the shoe nearer to the drum.
