Title: Improvements in or relating to the treatment of ores and the like containing titanium and iron
IPC: C22B34/12
Filed: 1926-09-17
Abstract: 279,219. Klein, C. A., and Brown. R. S. Sept. 17, 1926. Extracting; treating slag to recover metal therefrom.-In a process for the separation of titanium from iron contained in titaniferous ores by the reduction of the iron with the production of a titanium-containing slag, the slag is subdivided whilst in a heated condition from the reduction for the purpose of facilitating the elimination of the metallic iron from the slag. The subdivision of the slag is obtained by granulating the slag in a liquid bath or by directing a jet of fluid, e.g. steam, under high pressure on to the slag. The slag is separated from the water and in a dry state is passed through a magnetic separator. The treated slag is then finely pulverized and subjected to magnetic concentration to remove the last of the iron. When granulating the slag in a liquid bath, the liquid may be agitated by causing a strain of liquid to flow continuously through the bath or by a mechanical agitator. The titaniferous ore with carbon &c. is formed into briquettes as described in Specification 243,081, [Class 95, Paints &c.], and the briquettes are introduced into a blast furnace, the molten slag being then separated therefrom and treated as above. Specification 17049/86, [Class 82, Metals and alloys], is also referred to.

IPC: G03G13/28
Filed: 1973-05-15
Abstract: 1443004 Electro-photographic element; printing plate manufacture FUJI PHOTO FILM CO Ltd 15 May 1973 [15 May 1972] 23176/73 Headings G2C and G2H An electro-photographic recording element for use in the production of a printing plate comprises a support and a photo-conductive layer which has or is coated with a surface layer consisting only of a silicone rubber and having no photo-conductive substance uncovered. In the embodiments the support is conductively coated paper, grained aluminium treated with a silicate and coated with a styrene-alkyd resin or a polyester sheet coated with aluminium. Many other supports are also specified. The photo-conductive layer may be ZnO or polyvinylanthracene in a silicone rubber or a styrene-alkyd resin or polyvinylcarbazole and may be overcoated with a layer of silicone rubber optionally containing photo-conductive ZnO. A photo-conductive layer of graded composition may be made by coating a dispersion of ZnO in a silicone rubber on a support and allowing the ZnO particles to settle prior to curing the rubber. The various layers forming the recording element may be joined by an adhesive layer of a silicone rubber or a styrenated-alkyd resin. Many other photo-conductors and binders therefor are specified. The silicone rubber is preferably a one-part siloxane with terminal alcohol or oxime groups and may contain silica or a phthalocyanine as a filler. After exposure and development the element is suitable for use as a printing plate without the need for a fountain solution since the non-image areas are highly ink repellant. These areas may be enhanced further by treating them with an organic or inorganic acid to remove the photo-conductive substance from below the surface of the element. Many acids are specified and acetic acid is used to remove ZnO. Specification 1146618 is referred to.

Title: Improvements in or relating to draw-bar and buffing gear in particular for railway waggons
IPC: B61G9/02
Filed: 1933-08-24
Abstract: 410,996. Combined buffing and draw gear for vehicles. KRUPP AKT.-GES., F., Essen, Germany. Aug. 24, 1933, Nos. 23549 and 23550. Convention dates, Sept. 1, 1932 and Jan. 2, 1933. [Class 103 (v).] In a combined buffing and draw gear for railway &c. vehicles of the kind in which side buffers operate in conjunction with a continuous central drawgear equipped with buffing and draw springs, the latter springs are so arranged and associated with pivoted transverse levers that either on the occurrence of double-ended draw forces or double-end buffing forces the underframe is wholly or almost wholly relieved from the resultant stresses. According to the construction shown in Fig. 1, a divided draw-rod 48, 49 is employed so as to permit a certain amount of train slack and has pivoted to its ends the drawhooks 38, 39 and transverse levers 40, 41 which work in association with the buffer rods 36, 37. To allow a limited relative movement between the levers 40, 41 and the buffer stems, the levers work in slots in the stems terminating in stops 42-45. Each part of the draw-rod has a light springing arrangement 31-33 with a distance-piece 34 for the follower-plates 32, 33, while the inner ends of the rods are fitted with collars 26, 27 bearing against followerplates 24, 25, which are connected to the collars 26, 27 by rods 28, 29 and between which are interposed a spring 23 and distance-piece 30. When double-ended stresses occur in this arrangement, the follower plates 24, 25 approach and compress the spring 23, while each of the springs 31 is compressed by an amount corresponding to half the stroke of the spring 23. Some load is thus actually imparted to the underframe, but, by making the spring 31 of light construction, such load may be made relatively small. The provision of the springs 31 and the slots in the buffer stems furnish the requisite amount of train slack. Various other arrangements are described in which additional springs may be disposed around the buffer stems or the draw-hooks, and in which the main spring is located in a housing while the draw-rod springs may be replaced by friction springs or brakes.
