Title: Improved tubular electric condenser and method of manufacturing same
IPC: H01G4/38
Filed: 1920-06-07
Abstract: 145,008. Giles, G. June 16, 1919, [Convention date]. Condensers.-Tubular condensers are made of several units arranged along a common dielectric support each consisting of several elements placed one within the other and connected in parallel while corresponding elements of successive units are connected in series. In the section shown of a condenser of three units a, b, c, the elements consist of pairs of annular armatures a<1> a<2>, a<2> a<3>, and so on with intervening dielectric layers e, f, the elements of the three units being connected in parallel by plastic metal masses i, j embedded in the dielectric, which masses also connect in series the elements a<1>-e-a<2>, b<1>-e-b<2>, c<1>-e-c<2> of the several units a, b, c. Contiguous elements, such as a<1>-e-a<2>, a<2>-f-a<3> in a given unit thus have a common armature a<2>. The armatures a<2>, a<4>, c<2>, c<4> of the extreme units are connected by pieces k, l. The condenser may be constructed with impregnated paper by first winding on a mandrel a strip d of full width on which the armature c' and metallically continuous armatures a', b<1> are placed. A strip e of full width is wound over these and the armature a<2> and continuous armatures b<2>, c<2> are placed on this with a superposed strip f of full width and this is repeated until the outermost armatures a<5>, b<5>, c<5> are reached. Cavities at n, o are then cut in the dielectric and are fitted with lead or the like to connect the elements in each unit in parallel and corresponding elements in all the units in series. The whole is cased with paper m and is impregnated with bakelite or the like, or the impregnation may be done before the cavities are cut, the casing m being subsequently impregnated.

Title: An improved process and apparatus for the extraction of metal from ores
IPC: C22B11/10
Filed: 1935-07-17
Abstract: 464,675. Extracting metals by amalgamation. WHITE, HUGUES, & CO., Ltd., and PHILY, F. DE. July 17, 1935, No. 15426. [Class 82 (ii)] Gold is extracted from ores &c. by feeding the ore &c. in a finely divided condition on to the surface of a bath of mercury into which is dipped a solid body of large surface area, the immersion of the body drawing down into the mercury a thin layer of the ore particles. The gold is amalgamated and the amalgam is withdrawn at the bottom of the bath, the tailings separating from the solid body on its withdrawal from the mercury. If desired the amalgamation may be assisted by the passage of an electric current or by the addition of an activating substance such as sodium. The apparatus used consists of a trough 5 containing mercury in which is rotated slowly a cylinder 1 having on its surface a plurality of blades 2 made of iron or other material resistant to and not wetted by mercury, such as aluminium, wood, or glass, and arranged in planes normal to the axis of the cylinder. The ore is fed on to the surface of the mercury by a shoot 3, gold amalgam is removed at an outlet 6, and the tailings are carried up by the blades and pass down a shoot 4. A comb or like device may be provided to ensure removal of the tailings from the cylinder. The trough 5 may be shaped so that there is considerable clearance between the blades and the bottom where the amalgam collects. Any amalgam of silver or base metals can be removed by skimming, vents or overflows 9 being provided and sufficient mercury is continuously supplied to replace that carried out. Figs. 3 and 4 show forms in which the container is divided into a plurality of troughs, each with a rotating bladed cylinder and an amalgam outlet 7. The speed of rotation of the cylinders in the different troughs may vary. In Fig. 4 the blades of the cylinders are interleaved and a layer of water covers the mercury,the tailings passing down the shoot 4 into a vessel also filled with water from which they are removed by a conveyer 8. Alternatively instead of a container comprising a plurality of troughs, several separate containers may be arranged in series. The amalgam collected may be further concentrated by sedimentation and by means of a chamois leather. and the tailings may be treated to recover any mercury or amalgam carried over, e.g. by washing in pans arranged in cascade, one of the pans being preferably provided with a dam.

Title: Radiation-sensitive materials and methods of image formation
IPC: G03C1/725
Filed: 1975-04-15
Abstract: 1497452 Photo-sensitive material EASTMAN KODAK CO 15 April 1975 [15 April 1974] 15495/75 Heading G2C Photo-sensitive material comprises a cobalt III complex free of sensitizable anions and a photoreductant capable of forming a redox couple with the complex on exposure to radiation of wavelength greater than 300 nm. The redox reaction, which may be assisted by heating at 80-150‹C, releases at least one ligand, e.g. ammonia. The complex may be decompozable by the released liquid. The complex and reductant may be in the same or separate layers. The material preferably also contains a reductant adjuvant which is a source of hydrogen atoms (necessary when the photoreductant lacks an internal hydrogen source) and a binder (which may be a reductant adjuvant). The complex, reductant and adjuvant may be applied to a support in a common solvent. On exposure, an image may be produced in a separate image recording material, e.g. one which is visibly responsive to ammonia. The image-recording material may be contacted with the photo-sensitive material during exposure (preferably through a separation layer) or, when the redox reaction requires heat for completion, after exposure. The image-recording material may be photo-sensitive (to visible or UV light). An image may, alternatively be produced in the photo-sensitive material, e.g. by reaction of the non-reduced complex with a leuco dye or colour developer, or by reaction of the reduced complex with a compound containing a thioamide functional group. A multi-layer material may produce a multi-colour image. The photoreductant may be a disulphide, diazoanthrone, diazophenanthrone, aromatic carbazide, aromatic azide, diazonium salt, or aromatic diazosulphonate. Specific Examples of complexes, reductants, adjuvants, binders and imaging materials are given.

Title: Improvements relating to the sweetening of petroleum oils containing mercaptans
IPC: C10G27/04
Filed: 1951-07-04
Abstract: A petroleum oil containing mercaptans is sweetened by mixing it with an aqueous caustic alkali solution containing a substance which is capable of increasing the solubility of the mercaptans in the alkali solution, in the presence of oxygen or an oxygen-containing gas such as air, but in the absence of a catalyst for the oxidation of mercaptans to disulphides.  The petroleum oil, which may be a sour petroleum naphtha or benzine, may be subjected to a prior treatment with an aqueous caustic alkali solution, containing no solubility promoter, in the presence of oxygen or an oxygen-containing gas.  The alkali may be caustic soda and the solubility promoter may be commercial cresol. The treatment with the caustic alkali solution containing a solubility promoter may be carried out in two or more stages.  The sulphur content of the oil is unchanged by the treatment, the mercaptans being apparently converted to organic disulphides which remain in the oil.  No regeneration of the caustic alkali solution is necessary.
