IPC: C10G11/18
Filed: 1943-05-25
Abstract: <PICT:0573819/IV/1> Gasolines of low olefine content are obtained by the catalytic conversion of heavy oils in a first reaction zone under conditions giving a gasoline rich in olefines which are further treated in a second reaction zone to reduce their olefine content, the reaction conditions being controlled while the catalysts are regenerated in a common regeneration zone in which dense phase conditions also are maintained so that the catalysts in each zone are maintained in the dense phase.  Kerosene, gas, oil, reduced crude &c. is supplied through line 1 and passed through heating coil 6 to line 10 where it is mixed with hot regenerated catalyst and the mixture fed into base of reactor 11 maintained at 480-595 DEG  C., a weight-space velocity of 0.2 to 4 being maintained in the dense phase zone.  The converted vapours pass off through separator 13 to fractionator 17, from which gasoline is recovered overhead and passed through condenser 22 to receiver 25.  The gasoline is then fed through line 33, heating coil 38 into line 41 where it is mixed with catalyst and passed through converter 42 maintained at about 370 DEG C.  The gasoline stock may be mixed with a separate stock fed through line 28.  The used catalysts from both reactors are removed through conduits 67, 83 to a common regenerator 68 where carbonaceous deposits are burnt off by contact with oxidizing gases, the regenerated catalysts being returned to the respective reactors through conduits 10, 41.

Title: Improvements in or relating to valve-controlled conduits for fluids
Inventor: ARNOLD HUGH INGRAM
IPC: F16L37/107
Filed: 1951-04-11
Abstract: 715,383. Fluid-actuated valves. STERLING INDUSTRIES, Ltd. July 11, 1952 [April 11, 1951], No. 8460/51. Class 135. [Also in Group XXVIII] A valve controlled conduit, e.g. for filling a tank, has valve operating-means movable to positively close the valve or hold the valve open through a spring acting against e.g. a piston diaphragm subject to valve outlet or back pressure and which closes the valve automatically if the pressure exceeds a predetermined value. The conduit comprises a tank inlet 1 having a rim 2 carrying bayonet lugs 3 and notches 4 on its outer end face, and containing a non- return valve 5, the inlet co-operating with a hose outlet having a spigot 11 which can only be pressed into the inlet when outlet lugs 13 enter the notches 4, after which a sleeve 15 is rotated to bring a notched outlet flange 16 behind the bayonet lugs to secure the outlet and inlet together. The handle 42 is then turned to the position shown so that a crank and rod 40, 43, compresses a spring 45 contained within a piston 34 carrying an outlet valve 31, so that the valves 31 and 5 open. The piston slides in a cylinder 24 supported within the outlet, so that when fluid back pressure attains a certain value it acts on the piston and moves the valve towards its closed position against the spring and atmospheric pressure acting on the piston via passage 28. A cam 50 on the handle entering a notch 53 in the sleeve 15 prevents the sleeve being rotated to uncouple the outlet and inlet unless the handle is turned to close the outlet valve.

Title: Improvements in or relating to the manufacture of aliphatic anhydrides
IPC: C07C51/56
Filed: 1928-03-21
Abstract: 312,733. Dreyfus. H. March 21, 1928. Grant of Patent opposed. Addition to 280,972. Acetic, propionic, butyric, and other aliphatic anhydrides.-The process of the parent Specification, in which acetic anhydride is produced by heating acetic acid vapour in presence of a phosphoric acid, which may be deposited upon or mixed with porous materials, is applied to the production of other aliphatic acid anhydrides: and aliphatic acid anhydrides (including acetic anhydride) are produced with particular advantage when the phosphoric acid is deposited upon or mixed with carbon, charcoal. or carborundum. A suitable catalyst may be prepared by carbonizing a mixture of ortho-phosphoric acid and an organic substance such as cane sugar, or by mixing with or spreading upon carborundum a substance such as orthophosphoric acid or ammonium phosphate and heating, whereby meta- or pyrophosphoric acid is produced. The reaction may be effected by passing the vapour of the aliphatic acid over. the catalyst in tubes made of or lined with gold, platinum or the like at 300-600‹ C. at ordinary, increased, or reduced pressure. The catalyst may be regenerated continuously, for instance by circulating it between the reaction zone and a regenerating zone in which it may be heated to remove the water absorbed. The reaction vapours may be treated in any suitable manner to separate the anhydride; for instance by leading them through a fractionation column maintained at a temperature between the boiling-points of water and the anhydride; or by passing them through one or more solvents for the anhydride of higher boiling point than water, such as chlorbenzene, p-dichlorbenzene, benzyl ether, tetrachlorethane, paraffin oil, triacetin, phenetole, anisole, one or more cresols, or p-cresyl acetate; or the vapours may be condensed in presence of the vapour of an entraining liquid which carries away the water vapour, as described in Specification 303,772 ; or the vapours may be led under the surface of an extracting liquid insoluble in water and maintained below the boiling-point of water, as described in Specification 298,667; or the vapours may be passed over one or more water-binding substances below the temperature at which the vapours are produced but preferably above the boiling-point of water, as described in Specification 289,972. When the vapours are produced under pressure, the pressure should be released before the separation of the anhydride. The anhydride may be purified by distillation over anhydrous sodium or other acetate. The initial material may be dilute or concentrated acid. Examples describe the production of acetic and propionic anhydrides at 450-500‹ C.
