Abstract: 1,257,829. Carbon black. PHILLIPS PETROLEUM CO. 28 April, 1969 [29 April, 1968], No. 21447/69. Heading C1A. In a process for the production of carbon black in which a hydrocarbon feedstock flowing through a cylindrical reaction zone is enveloped in a stream of hot combustion gases produced in a cylindrical combustion zone having a greater diameter than the reaction zone and positioned immediately upstream therefrom, the combustion gas is produced from the combustion of a fuel in the presence of a free-oxygen containing gas wherein the oxygen is in an amount of from 2À2-2À5 times the stoichiometric amount required for the complete combustion of the fuel and the fuel and/or free oxygen containing gas is preheated to a temperature of from 530- 1000‹ F. The hydrocarbon feedstock heated to 430‹ F. is introduced via burner 8 where it passes into combustion zone 5 and is enveloped in a hot gas comprising air (preheated to 530‹ F.) and fuel gas in a ratio of 22 to 1. The hot combustion gas is introduced tangentially to the flow of feedstock via conduit 9. Carbon black is produced in reactor 6 and passed through outlet 10.

Abstract: 1,265,486. Beneficiation of molybdenite concentrate. CONTINENTAL ORE CO. Ltd. 21 May, 1969 [21 May, 1968], No. 24175/68. Heading C1A. A process for the beneficiation of molybdenite concentrate comprises pre-heating the concentrate under inert conditions and contacting with oxygen at an initial temperature of at least 385‹ C. in order to form the trioxide, the maximum temperature reached during this contact being with the range 500-900‹ C. Pure oxygen may be used as such or diluted with air or oxygen. The pre-heating may be in an inert atmosphere preferably in a fluidized bed, or in a container substantially filled with concentrate. The process may be continuous, the concentrate being carried through a pre-heating zone and then through an oxidation zone, the latter preferably being a shallow static zone incorporating a rake. The effluent gases may be cooled, filtered and passed through ethanolamine whereupon the SO 2  is removed but may be regenerated by heating the ethanolamine. After oxidation the concentrate may be crushed and reroasted in air and may have its copper content reduced by treatment with hydrochloric acid and ferric chloride, thereafter adding first sodium carbonate or ammonium chloride to give a pH of 1À8-4À5 and separating the precipitated ferric molybdate and adding secondly sodium carbonate to give a pH of 5À7-6À5 so as to precipitate the copper carbonate.

Abstract: 1296076 Photoconductive layer EASTMAN KODAK CO 10 April 1970 [16 April 1969] 17145/70 Heading H1K A photoconductive layer is made by first dissolving a pyrylium, thiapyrylium or selenopyrylium sensitizing dye in an organic solvent or solvent mixture in the absence of any other photoconductor, adding an electrically insulating polycarbonate to the dye solution and dissolving the polymer therein and thereafter coating the mixture in a thin layer and allowing it to dry under conditions which cause a multiphase heterogeneous photoconductive layer to form. A solution of the sensitizing dye and the polycarbonate is formed in dichloromethane and a triphenyl methane photoconductor added. The mixture is filtered and coated on to a polyethylene terephthalate sheet having a layer of nickel thereon. The layer of the photoconductive mixture is dried at elevated temperature.

Abstract: 1314450 Making honeycomb girders; welding by fusion METALLEICHTBAUKOMBINAT VEB 3 June 1970 26789/70 Headings B3A and B3R A method of making honeycomb girders 32 comprises clamping a pair of webbed girders on opposite sides of a clamp beam 7 in side-byside, spaced, parallel relationship, with their webs in a common plane, moving the clamped girders to a processing station 2, 2<SP>1</SP> where each web is cut along a line having a trapezial waveform, turning the two inner halves through 180 degrees about the longitudinal axis of the clamp beam and welding the girder halves together to form a honeycomb girder. I-section girders are clamped in pairs at a station 1 and moved to the stations 2, 2<SP>1</SP> on a roller conveyer 9. A cutting head 11 cuts through the webs of a pair of girders and when the girders at the station 2 are cut, the head is swung over to the station 2<SP>1</SP> to cut the girders of the second pair. After cutting, pusher means 10 move the clamped halves outwardly, while turning means 13 is raised to the level of the beam 7, which is provided with a shaft end (20) and a clutch member, Fig. 6 (not shown). A clutch (19) is engaged and a motor (18) rotates the beam through 180 degrees about its longitudinal axis. The outer girder halves are moved back by the pushers 10 after the turning means 13 has been lowered and the lands 23 of the opposed cut edges are brought into contact. Support arms 25 are moved up under the edges to be joined and four torches 30 simultaneously weld four pairs of lands 23 of the girders at the station 2. The welding head 28 then moves along a track 27 to weld the next group of projections and so on. When the girders have been welded together, the head 28 moves to an intermediate station 31. In the meantime, the girders at the station 2<SP>1</SP> have been cut and the inner halves turned. These girders are then welded either by the head 28 following a circulatory path or by a second welding head 28<SP>1</SP> following a reciprocatory path. A plurality of cutting heads 11 may also be provided, in which case there is an additional intermediate station 31<SP>1</SP>. The cutting and welding heads are selectively controlled from the stations 31, 31<SP>1</SP>, preferably by a programme control system. While the girder at station 2<SP>1</SP> is being welded, the completed girder 32 from station 2 passes on the conveyer 9 to a lowering station 3. The girder is released so that it lies on a table (36), Fig. 7 (not shown), and the clamp beam 7 with its associated clamps moves back to the station 1.
