Abstract: 545,658. Cracking oils. UNIVERSAL OIL PRODUCTS CO. April 16, 1940, No. 6872. Convention date, May 5, 1939. [Class 32] Relatively light and heavy oil fractions are simultaneously subjected to catalytic conversion in separate reaction zones in the presence of catalysts comprising silica and a compound selected from the groups comprising alumina zirconia, vanadia and thoria, and the cracked products are passed into a common fractionating tower to recover antiknock gasoline and light and heavy fractions which are supplied to the conversion zones. Crude oil is fed by a pump 3 and line 6 to a fractionating tower 8 where together with the products of the reaction it is fractionated into (a) gasoline recovered through line 9 (b) a light fraction taken off through line 24 and a heavy fraction removed by pump 42 from the bottom of the tower. The light and heavy fractions are vaporized and cracked in heating coils 29, 45 and reactors 37, 53, respectively, and the products obtained are mixed in line 69 and passed into an insulated reactor 71 where further cracking occurs. The products are passed through a separator 74 to remove ends and are then fractionated in thetower 8. Alternatively the products from the re-actors 37, 53 are passed directly to the tower 8. The re-actors 37, 53 comprise a plurality of tubes 34 arranged in parallel and filled with catalytic material. Pairs of re-actors may be used so that the catalytic material may be alternately on stream and undergoing regeneration by hot gases admitted through a pipe 56. The temperature of the reaction is controlled by passing hot or cool gases through the chambers 37, 53. Catalysts specified comprise pellet of alumina and silica the percentage of either component ranging from 2-50 per cent.

Abstract: 1,039,821. Extracting continuously-cast lengths. UNITED STATES STEEL CORPORATION. Feb. 20, 1964 [March 4, 1963], No. 7217/64. Heading B3F. [Also in Division H2] A travelling receptacle 2, driven by an electric motor 7, lowers severed lengths of a continuous casting 1. A sensing finger 11, in its uppermost position when the receptacle is empty, is coupled to a contact controller 20 (see Division H2). The motor 7 causes high speed upward travel of the receptacle 2, but upon approach of the receptacle and casting 1 to predetermined spacing therebetween, finger 11 is partially depressed whereby controller 20 reduces the motor speed. Upon further partial depression of the sensing finger, all contacts are opened to stop receptacle movement. Upon further approach of casting 1 and receptacle 2, but short of actual contact between the casting 1 and fixed receptacle fingers 10, the sensing finger 11 is actuated so that the receptacle moves downwardly at low speed. When the casting 1 engages fixed fingers 10 and the sensing finger 11 is fully depressed after severance of a length the downward speed of the receptacle is increased to remove the severed section from interference with the oncoming product. The low speeds of receptacle travel are such as to allow the receptacle to follow the movements of the lower end of the unsevered product, a heatinsulating air gap being maintained between the casting and fingers 10.
