Title: Improvements relating to the removal of metal compounds from petroleum fractions
IPC: C10G21/20
Filed: 1960-10-10
Abstract: A process for reducing the content of metal compounds in distillate petroleum fractions boiling above 250 DEG  C. comprises contacting a petroleum feedstock having at least a proportion of metal compound-containing distillate material boiling above 350 DEG  C. with a pyrrolidone or a substituted pyrrolidone, for example 2-pyrrolidone, for example at 0-25 DEG  C. and atmospheric pressure, and recovering a product having a reduced content of metal compounds. The metal compounds to be removed may be a porphyrin, for example a vanadyl or nickel porphyrin.

Abstract: 1370987 Hydrophobic materials RHONEPROGIL 25 July 1972 [26 July 1971] 34768/72 Heading C1A Porous, divided or colloidal materials, e.g SiO2 gel, having surface OH groups are rendered hydrophobic by treatment with a compound of the formula R-Si-X, where R is an organic radical having a M.W. of at least 150 and containing a hydrophilic substituent, and X is a radical or atom capable of reacting with the OH groups to groups of the formula -O-Si-R. The R group may have a M.W. of up to 4000. The Si-containing compound may be prepared by the addition reaction of a compound containing a terminal vinyl or allyl group and a hydrophilic substituent with a silane. Alternatively it may be prepared by copolymerizing a vinyl monomer having a hydrophilic substituent with an unsaturated silane. The bodies may be dried before treatment or modified hydrothermally in the presence of NH3. Treatment may be carried out by contacting the bodies with the Si-compound in the vapour or liquid phase, optionally in a solvent, washing with a solvent for the Sicompound, drying and then finally heating to remove any non-bonded Si-compound. The SiO2 gel bodies may be microspheres having 0�5-4 OH groups per 100 �<2>, a diameter of 100-200 �, a surface area of 6-130 m.<2>/g., a pore volume of 0�8-1�0 ml./g., and a pore diameter of 108-5200 �.

[Class 75(i)] [Also in Group XII] In a liquid fuel burner for an industrial furnace comprising a series of parallel air supply tubes 4, Fig. 6, each containing a fuel pipe 9 supplying fuel to a burner head 12 and mounted in a common protecting casing 5 adjustable longitudinally through the furnace wall, the tubes 4 and pipes 9 are arranged in two or more different groups side by side each in a protecting casing 5 and each comprising two or more tubes 4 and pipes 9 capable of being put individually into and out of action. The burner is mounted on a carriage 6, Fig. 2, running on rails 7 and directs the flame or flames parallel to the hot-air current from the flue 3 leading from the heat recovering and regenerating units. The flue 3 is divided by partitions into as many ducts as the burner has groups of tubes, each duct being controlled by an individual damper. The tubes 4, which may be supplied with hot air from the flue 3, are fixed to a plate 19 carrying a cross piece 20 on a small trolley 21 running on rails 23 carried by the main carriage 6, so that the tubes 4 may be adjusted in relation to the casings 5 which are fixed to a plate 24 hinged at 26 to the girders 27 of the carriage 6 and fixed rigidly to the rails 23. The inclination of the burner within the furnace may be adjusted by tilting the rails 23 and the plate 26 by means of a screw 29 operated by a handwheel 28. The casings 5 are cooled by circulating water. A screen 34 is adapted to close the furnace opening 8 after the withdrawal of the burner and the raising and lowering movements of the screen may be controlled by the change in position of the carriage 6 through pulleys 35 and cables 36, 37.

Abstract: 522,206. Protective cut-out arrangements. AKT.-GES. BROWN, BOVERI, & CIE. Dec. 6, 193B, No. 35501. Convention date, Feb. 9. [Class 38 (v)] In protective arrangements in which polyphase networks are rapidly disconnected on arcing- faults and immediately reconnected, the switching arrangements of the individual phases are each actuated by separate relays in such a way that, whatever the extent or nature of the fault, the minimum of phases is opened by the switches to interrupt the fault in all the affected phases. Thus, in a three-phase fault, two phases would be disconnected, leaving the third connected so as to assist in maintaining the synchronism between the " disconnected " parts of the system. The Specification discusses the effects of extinguishing-inductances and refers to pneumatically-actuated power switches with air-blast arc-quenching, in series with disconnect switches for finally opening the circuit'if the opening and reclosing of the power switch does not clear the fault.
