Title: Thermal cracking of a heavy hydrocarbon feed stock in a regene rable melt
IPC: C10G9/40
Filed: 1972-09-12
Abstract: 1414780 Salts; double salts EXXON RESEARCH & ENG CO 12 Sept 1972 [5 Oct 1971 14 Aug 1972] 42307/72 Heading C1A [Also in Division C5] A heavy hydrocarbon feedstock is cracked by contact with a melt at a temperature above the melting point of the melt but less than 1200 F. The melt consists, apart from impurities and contaminants formed in the cracking, of an alkali (that is an oxide or hydroxide of a metal of Group IA or an oxide or hydroxide of a metal of Group IA in combination with an oxide or hydroxide of a metal of Group IIA) and a "glass-forming" oxide of Ti, V, Mo, W, B, Al, Ga, Si, Ge, P; As, Sb, Bi, Se, or Te. Preferably the mole ratio of alkali to glass-forming oxide is from 0À01 to 5. Either or both of the components may be replaced by their pre-cursors or the product of reaction between them. After cracking, the melt can be regenerated by contact at a temperature between the melting point and 2000 F. with oxygen, carbon dioxide, steam or their mixtures. When the feedstock contains sulphur or ash-forming components, these are largely retained in the melt. They can be removed by bleeding off a proportion of the melt and treating it with steam and CO 2 . If the sulphur compounds in the melt are not sufficiently reduced to sulphides in the cracking step, they may be reduced in a separate step.

Title: Improvements in or relating to plate-shaped fuel elements, and method of assembling same
Inventor: DAVID PAUL
IPC: G21C3/36
Filed: 1964-10-19
Abstract: 1,024,203. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Oct. 19, 1964 [Oct. 18, 1963], No. 42606/64. Heading G6C. [Also in Division B3] A fuel plate, for assembly with similar plates to form a stacked fuel element, comprises fuel enclosed in a protective sheath, there being no fuel in the end portions thereof, the end portions being of the same thickness as the remainder of the plate, and being deformed out of the major plane of the plate and machined so that a plurality of such plates can be assembled by abutting their machined faces to form a fuel element having spaces between the plate faces for coolant circulation. A series of such plates are seen assembled in end view, the abutting faces 11 of the ends being joined by electron beam welding. Each plate may be bent to a U-shape instead of the S-shape illustrated. The advantage offered by the invention is that since the faces 11 to be welded do not lie in the plane of the plates, the electron beam penetration during welding is no longer critical; hitherto if the beam was slightly too deep, splashing of the plates, occurred due to run-through of molten metal, and if it was too shallow, an unwelded " crack" remained, which lead to rapid corrosion and extension of the fault.

A timing circuit comprises a capacitor charged by a grid-controlled valve so as to define a first time period, the capacitor being discharged at the end of the time period and recharged when required so as to define a second time period. A circuit is described for controlling the magnetron of a microwave oven. Terminals 27, 28 are connected to an alternating voltage supply at the same time as the filament of the magnetron is energized. Capacitor 2 begins to charge via valve 1, the charging time being dependent upon resistors 8, 9, 10 and capacitor 6 connected in the grid, cathode circuit feedback from cathode to grid tending to reduce the charging rate. After about two minutes, capacitor 2 is charged sufficiently to energize the control relay 5 which also energizes an auxiliary relay 3. Capacitor 2 is now discharged via contacts 15 and the coil of relay 5; capacitor 6 is discharged via resistor 12 and contacts 20. Once the auxiliary relay 3 has been energized, push-button 14 may be operated so as to energize an operating relay 4, contacts 25 of which supply HT to the magnetron. Capacitor 2 now begins to recharge via valve 1, the charging time being dependent on capacitor 6 and resistors 7, 9, 10 in the grid/cathode circuit. When capacitor 2 has charged sufficiently to energize the control relay 5, the operating relay 4 becomes released, disconnecting the H.T. from the magnetron.
