Title: Method and apparatus for cracking hydrocarbons
IPC: C10G11/18
Filed: 1959-12-07
Abstract: <PICT:0901287/III/1> Two hydrocarbon feeds are cracked by passing the first through a first conversion zone with a dilute suspension of finely divided solid material, preferably cracking catalyst, at elevated temperature to effect partial conversion, separating the solid and first product in a second conversion zone, above a dense fluidized bed of the solid, the separated solid from the first conversion being deposited on the fluidized bed, passing the second feed through the fluidized bed at a lower temperature than in the first conversion and recovering products from both conversions above the fluidized bed.  The cracking is effected in a unitary apparatus as illustrated. Catalyst, e.g. silica containing alumina, magnesia, boria or zirconia, is regenerated in fluidized bed 6 supported on a grid below which oxidizing gas is introduced.  The regenerated catalyst enters a stripping wall 42 where it is stripped by gas entering through distributer 46.  It is then entrained by fresh feed which may be mixed with steam which enters through the hollow movable plug 52.  The suspension of catalyst in vaporous oil moves up through one or more visers 56 at 20-100 ft./sec. and is discharged at its upper end into a reactor containing a fluidized bed of catalyst 4. By means of a baffle as illustrated or by using a closed end riser having elongated slots in the side the mixture of catalyst and vapour is directed horizontally or downwards and the catalyst settles on the fluidized bed.  The second feed, e.g. a recycle stock, is injected through distributer 68 and fluidizing gas is injected under the supporting grid. Products are recovered via the cyclone 62.  Catalyst passes through slots 12 into the segmental stripping zone 8 fed with stripping gas through distributer 16.  Thence the catalyst returns to the regenerator through standpipe 18 controlled by plug 22. Temperature in the first zone may be 1000-1100 DEG  F. and contact time below 4 seconds, and the second zone may be at 900-960 DEG  F. with a contact time of 3-10 seconds.  The WHSV may be 0,25-10 in each reaction zone and the weight ratio of catalyst to oil 2 to 30.  An overall pressure of 0-50 p.s.i.g. is maintained.

Patent GB-422452-A (GB)
Abstract: 422,452. Cash registers. ANKERWERKE AKT.-GES., Bielefeld, Germany. July 30, 1934, No. 22216. Convention date, Aug. 26, 1933. [Class 106 (i)] [See also Group XVI] Cash registers adapted to record and register items of a plurality of monetary systems.-In a cash register for registering and recording amounts in different currencies and provided with currency-selecting and amountsetting means, the currency-selecting means controls the positions to which the amount-setting means can be set. The invention is described as applied to a differentially-set cash register having six setting levers 1, Fig. 1, for the units and higher denominations, two levers 2, 3 for shillings or the tenths and hundredths of a decimal system, two levers 4, 5 for pence and farthings, and three levers 6-8 for selecting the particular monetary system. Each lever communicates its setting to a type-wheel 16, Fig. 2, with which a pair of printing platens 17, 18 co-operate for printing upon a record strip and inserted slip, the type being formed either with points or as inclined knife-edged plates to penetrate or incise the paper. The machine may be provided with a single group of totalizers for accumulating the amounts in each currency, the desired totalizer being selected by the currency-selecting levers. To prevent the adjustment of the setting lever 2 past the ten position when the lever 6 is in its uppermost position to select the British monetary system, a locking-arm 26, Fig. 4, fast on a shaft 23, presents a shoulder 32 in the path of a stud 33 on the lever 2. However, upon the adjustment of the lever 6 out of its uppermost position to select a decimal system, the arm 26 is rocked clockwise to free the lever 2, the shaft 23 being connected for this purpose to the lever 6 by means of an arm 24, Fig. 2, a cam slot 22 in which embraces a stud 21 on the lever. This adjustment of the lever 6 through an arm 25, Fig. 3, on the shaft 23, serves also to lock the pence and farthing setting levers in zero position by interposing a shoulder 28 on the arm in the path of studs 29 on the levers. Curved surfaces 27, 31 on the arms 25, 26 co-operate with the studs 29, 33 respectively to prevent adjustment of the currency-selecting lever 6 into its uppermost position after the movement of lever 2 past the ten position, and adjustment of the lever 6 from its uppermost position after the movement of either of the levers 4, 5 from zero position.
