Abstract: An apparatus for preventing wear of an electrode holder on a discharge electrode frame of an electrostatic precipitator includes an electrically conductive member having a central portion generally contoured to a shape of an electrode holder. The apparatus is fastened to at least one of the electrode holder and an end portion of a discharge electrode such that, when the end portion of the discharge electrode is attached to the electrode holder, the electrically conductive member is disposed between the end portion of the discharge electrode and the electrode holder.

Abstract: An electrostatic precipitator includes a dust-collecting electrode group and a discharge electrode group arranged in the recited order with respect to the gas flow direction of a gas to be treated in the electrostatic precipitator. The discharge electrode group includes a plurality of discharge electrodes, each of which is made of a rectangular metal plate. The longitudinal edges of each plate form semicircles, with a series of saw-toothed portions having tips protruding from between each pair of semicircles. The dust-collecting electrode group includes a plurality of dust-collecting electrodes, each of which is made of a chain suspended adjacent the discharge electrode group at a predetermined spacing. The chains of the dust-collecting electrode groups are suspended so that they can rock back and forth.

Abstract: A suspension device and a rapping mechanism for electrodes in a high voltage supplied electrostatic precipitator, wherein the suspension device has at least one horizontally arranged supporting element from which a number of electrodes are suspended, the supporting element being mounted inside a precipitator housing, and wherein the rapping mechanism is of the type which transmits a rapping influence to the uppermost ends of the electrodes. The electrodes are pivotably suspended, preferably eccentrically, and are stabilized in a substantially vertical position. The supporting element receives impact or vibrating influences supplied by an impact hammer or vibrator in the longitudinal direction of the element, while the electrodes are substantially free of play in this direction such the impact or vibrating influence on the element is imparted to the electrodes.

Abstract: A heat developable light-sensitive material comprising a support with at least one layer thereon and containing at least (a) an organic silver salt, (b) light-sensitive silver halide or a silver halide-forming component and (c) a reducing agent with (d) an iron family compound in at least one layer on the support.

Abstract: A heat developable, photographic material comprising, in reactive association, (a) a photosensitive, transition metal carbonyl compound, (b) an oxidation-reduction image-forming combination comprising (i) a tellurium (II) or (IV) compound as an oxidizing agent, with (ii) a reducing agent, and (c) a binder can provide an improved non-silver image. After imagewise exposure of the heat developable material, an image can be developed by merely heating the material.

Abstract: Method comprises (a) applying to a supporting surface a coating comprised of a photosensitizable water-soluble polymer, a soluble dichromate photosensitizer for the polymer, a soluble vanadate, and particles of the pattern material; (b) exposing the coating to a pattern of actinic radiation until exposed portions of the coating are rendered insoluble; (c) and flushing the exposed coating with an aqueous solvent to remove soluble portions of the coating, while retaining the insoluble portions of the coating in place.

Abstract: In the method disclosed, a supporting surface, such as the inner surface of the faceplate of the tube, is coated with a photosensitive polymeric film containing about 5 to 80 weight percent of at least one member of the group consisting of certain diol ethers and diol alkanes. Then the film is exposed to a light image to produce regions of greater solubility and regions of lesser solubility. The film regions of greater solubility are removed, and then the entire faceplate with its regions of less solubility is overcoated with a layer containing particles of screen structure material. The retained film regions and the overcoating thereon are removed leaving the screen structure adherent in the areas of greater solubility. By including a diol ether or diol alkane in the film, the exposure time may be shortened significantly without substantial loss of adherence.

Abstract: The present invention relates to light-sensitive photographic material with a light-sensitive heavy metal compound, e.g. a silver halide, and a spectral sensitizer. The spectral sensitizer is a compound in which the radicals of a sensitizing dyestuff are covalently bonded to amino, imino, hydroxyl, mercapto, carboxylic acid or carboxylic acid amide groups of a natural hydrophilic colloid, preferably gelatin.The invention also relates to new sensitizing dyes which are dinuclear cyanine dyes or merocyanine dyes which have attached either to a heterocyclic nucleus of the dye or to its methine chain a group which is reactive with a hydrophilic colloid.

Abstract: Non-conductive real images are formed on substrates by depositing reducible metal salt compositions thereon from an aqueous acidic solution of pH 1.5-5 containing bromide ions and exposing the coated substrates to radiant energy to reduce the metal salt to metallic nuclei and to produce a real image of metal, which is intensified and built up by electroless metal deposition. The metal salt composition can either be selectively deposited and then exposed, or uniformly deposited and then selectively exposed, to produce the real image.
