Title: Process and apparatus for making carbon black
IPC: C09C1/50
Filed: 1950-05-12
Abstract: <PICT:0673155/III/1> <PICT:0673155/III/2> <PICT:0673155/III/3> A furnace for the production of carbon black wherein a hydrocarbon injector tube is centrally situated in the inlet end wall and is surrounded by a plurality of burners parallel thereto positioned near the side walls, comprises a combustion chamber in which the distance between opposing flat inlet and exit end walls is 0.25 to 2 times the distance between the side walls, an outlet orifice in the centre of the exit wall having an area of 5-25 per cent of the cross-sectional area of the combustion chamber and a reaction chamber communicating with the combustion chamber through the orifice having a volume equal to at least 45 per cent of the volume of the combustion chamber and a cross-sectional area at least equal to that of the orifice.  The cross-section of orifice, combustion and reaction chambers is preferably cylindrical.  In Fig. 1 the hydrocarbon inlet pipe 38 passes through an opening of larger diameter in the inlet wall 22 of the combustion chamber 18 so as to provide an annular passage 36 for cooling air from a plenum chamber 26.  A plurality of burners 44 supplied with fuel from jets 48 and air from the plenum chamber are arranged perpendicular to the end wall 16 of the combustion chamber. The orifice 54 lets into a section chamber 20 which may, as shown in Fig. 4, be larger than the orifice.  The inlet end wall of the combustion chamber may be formed by a loose fitting adjustable block 78, Fig. 5, leaving an annular passage 80 between it and the chamber wall.  A circular burner pipe 92 injects fuel into the passage through a plurality of orifices preferably at 45 degrees to the side walls.  In operation a combustible mixture of fuel and an oxygen containing gas in a proportion of 90-125 per cent of that required for complete combustion of the fuel, is injected at such a rate that the combustion gases pass through the combustion chamber at 150-600 c.f.m., perpendicularly on to the exit end wall to form violent turbulence.  A gaseous hydrocarbon is injected axially into the combustion chamber as an expanding cone. Specification 672,074 is referred to.

Title: Production of sintered metal bodies
Inventor: KOLSKI THADDEUS LEONARD
IPC: B22F3/11
Filed: 1965-03-22
Abstract: In a process for producing porous sintered bodies consisting e.g. capacitor anodes, essentially of Ta, Nb or Ta-Nb alloys, a powder mixture of a) at least one of Ta, Nb or Ta-Nb alloys and b) a more volatile metal selected from Ti, V or Ti-V alloys is compacted and heated in the range from 1600 DEG C. to within 200 DEG C. of the melting temperature of component a) and continuing the heating until at least 80% by weight of component b) has vaporized and been removed.  The powder mixture contains 5-90% by weight of component b) and the powder particle size is less than 50 mesh (U.S.), preferably minus 100 plus 200 mesh. The heating may be effected under vacuum or under a stream of argon.  The mixture may alternatively be hot pressed.  The powder mixture is formed by melting the metals together, hydriding the ingot, grinding and dehydriding or by coprecipitation 1% of stearic acid is added as a binder. The powder mixture may be compacted around a Nb wire which acts as a connector when the body is used as a capacitor anode.  The sintered body is anodized in 0.1% H3PO4 at 200 volts.  The anodized sintered anode may be impregnated with Mn(No3)2, heated, and re-anodized.ALSO:A sintered porous anode of N6-Ti is anodised, impregnated with Mn(NO3)2 and heated to form a coating of MnO2. The anode was then re-anodised and coated with graphite by dipping in a colloidal graphite slurry containing 7% solids.  An electrically conducting coating of epoxy resin was then applied and a copper cathode connector wire was imbedded in the coating.

Abstract: 610,996. Umbrellas. PARMENTER, E. H. April 18, 1946, Nos. 12039 and 19163. [Class 134] An umbrella has a skirt 10 made wholly or partly of transparent woven textile or other material such as synthetic plastic material, and is attached to the periphery of the umbrella cover. The skirt is extended or collapsed by means of cords 12 attached at one end to the free edge of the skirt, which may be weighted, passing through eyelets 11, 13, and 14 and attached at the other end to the ring 15. Alternatively they may pass through eyelets thereon and be attached to the ring 4, thus reducing the operating movement of the ring 5.

Title: Improvements in or relating to loading coils for duplex telephone circuits
IPC: H01B11/16
Filed: 1927-05-10
Abstract: 271,456. Siemens & Halske Akt.-Ges. May 19, 1926, [Convention date]. Loading circuits to improve transmission.-In a phantom circuit loading coil in which the windings are symmetrically distributed over an annular core, the coil windings of each of the four conductors are subdivided into sections which are uniformly distributed over the four quarters of the core, the windings of the two physical circuits being wound in opposite directions. When the windings are divided into four sections, the two windings of each of the physical circuits A1-E1, A2-E2 and E3-A3, E4-A4, Fig. 4 begin at opposite points on the core, and one section of each winding is wound on each core quarter, the sections increasing their distance from the core as they advance round it : for example, the second section of the winding A1-E1 is wound over the first section of the winding A3-E3, the third section of the winding A1-E1 over the second section of the winding E3-A3, and so on. This ensures a symmetrical distribution of the parasitic capacities between the windings of different physical circuits and between the windings and the core and the cover. According to a modification these capacities may be reduced in number by distributing the winding sections so that the second sections of each winding constitute the third layers from the core and the third sections constitute the second layers. The windings may be subdivided into a number of sections which is a multiple of four in which case the above arrangement is repeated one or more times.
