Title: Improvements in or relating to deasphalting operation
IPC: C10G55/06
Filed: 1952-12-18
Abstract: Residual oils containing asphaltic constituents are purified therefrom and converted into gasolines &c. of desired boiling range by subjecting the residual oil to mild cracking, e.g. temperatures of the order of 750-920 DEG  F., removing fractions boiling below 650 DEG  F. from the product and treating the residuum with a deasphalting solvent to separate the asphaltic constituents.  The deasphaltized residuum may then be cracked in presence of fluidized catalysts and gasloine &c. recovered from the cracked products.  An asphaltic crude is fed through line 2 to a distillation zone where the crude is fractionated into (a) hydrocarbon gases recovered through line 3; (b) naphtha through line 4; (c) heavy naphtha through line 5 and gasoil through line 6.  The reduced crude is fed through line 7 into a visbreaking zone 10 and the products withdrawn through line 70 to a distillation zone 71 where fractions boiling below 650 DEG  F. are withdrawn through lines 72, 73, while the residual oil is fed to a deasphaltizing zone 8 where it is contacted <PICT:0731721/III/1> with a solvent, e.g. propane or butane, fed through line 9.  The asphalt and solvent pass to a still 54 to recover the solvent through line 55 and the asphalt through line 56. The asphalt free fraction is fed to still 15 where residual solvent is recovered through line 50 and recycled to zone 8.  The asphalt free oil, mixed if desired with the gasoil fraction from line 6 is fed through line 51 to a fluid catalytic cracking plant comprising reactor 22, regenerator 30, and product fractionator 24 where the cracked products are separated into gasoline, heating oil, recycle oil and bottoms.

Abstract: 1,014,855. Tubular heat exchangers; water tube steam boilers; superheaters. FOSTER WHEELER Ltd. Sept. 6, 1962 [Sept. 7, 1961], No. 32177/61. Headings F4A and F4S. In a tube and shell heat exchanger, for use in nuclear power plants having gas cooled reactors, one or more prefabricated heat exchange units are contained in the shell, each comprising an inlet and an outlet header joined by a bank of substantially similar tubes, and each tube having a succession of U-bends such that it is made up of at least one cluster of tube lengths running lengthwise in the shell, corresponding clusters being positioned side by side to give substantially uniform tube distribution over the shell. As shown, Figs. 6 and 7, each tube cluster is in the form of a hexagon in crosssection, with parallel sections joined by U-bends 23, the cluster being made rigid by means of pegs 32 on the upper U-bends held in a spacer plate 34. The portions of the tubes between the U-bends may have longitudinally fins or studs or pins on their outer surfaces, and each cluster may be twisted about its central longitudinal axis to a helical form to improve heat transfer. A number of hexagonal clusters are formed into a heat exchange unit, with a branched radial header 14, each unit occupying a 60-degree sector of the shell 10, Fig. 5, identical units filling the remaining sectors, which may be separated by partitions 28. Each heat exchange unit may have the inlet and outlet headers at the same or at opposite ends of the unit, while tube clusters may run the full length of the unit or, Fig. 3, each tube may have several clusters arranged end-to-end within the length of a single unit. The shell may contain one set of heat exchange units set side-by-side in sectors, or several groups of units may be fitted end-to-end into the shell, not all groups being formed of units of the same type. A vapour generator built according to the invention, Fig. 11, comprises evaporator units " A," superheater units " B," and economizer units " C " end-to-end in a single shell. The heating fluid enters at 24 and leaves at 26, the inlet 24 being in a rotatable end cover to the shell, so arranged that individual heat exchange units can be lifted out through inlet 24 for servicing.

Filed: 1923-12-28
Abstract: 233,005. Marks, E. C. R., (International Cigar Machinery Co.). Dec. 28, 1923. Cigar-making machines.- In cigar-making machines constructed to prevent opening out of the bunch at its transfer from the feed table to the rolling mechanism, the rolling element or chianti belt 16 is moved up to form an extension of the feed table 14 by a device which is independent not only of the feeding means and rolling element but also of the rolling table 15. The chianti belt 16 is raised level with the feed table 14 by a platen 19 on a plunger 20, and the charge of long filler tobacco is pushed off the table by a plunger 11. The plunger 20 is raised and lowered by a two-armed lever 22, 23, operated by a cam 26 on a shaft 28. For clamping the charge on the belt and for forming the loop in the belt, an inverted trough 32 carried on a plunger 33 is moved down on to the charge by a two-armed lever 35, 36 actuated by a cam 38 on the shaft 28. The trough 23 descends with the charge and belt, thus forming a loop in the belt; then the rolling apparatus 18 comes into operation and the trough 32 rises. To maintain the plungers upright, parallel bars 29, 40 are pivoted to them and to uprights on the bar 24 on which the two-armed levers are fulcrumed.

[Also in Division G3] A circuit which reduces the drop in signal current to release a relay 47 after energization comprises a full or half-wave rectified unsmoothed supply 30, 42 charging through rectifiers 32, 56 a capacitor 54 which is shunted by the emitter 13 and base 15 of a transistor 11, thus holding transistor 11 conductive and another transistor 12 non-conductive. A signal from a source 82 fires a transistor 70 which shunts the input of transistor 11, cutting it off, thus rendering transistor 12 conductive hence relay 47 is energized. At each succeeding half-cycle the voltage on capacitor 54 is reduced by a voltage proportional to the tapping voltage 52 on a potentiometer 51, this reduction being within the relay differential, and which reduces the drop in signal current necessary to release the relay. The arrangement may be utilized to control an automatic heating system in which the signal source 82 is responsive to temperature and the relay controls the heating medium. An embodiment is described employing two transistors 11 sensitive to signal polarity operating two relays controlling a reversible motor. Another embodiment discloses a temperaturesensitive bridge circuit fed from a separate secondary winding on the transformer 20-22 which bridge replaces the source 82.
