Patent EP-0065042-A1 (EP)
Inventor: KALINA ALEXANDER I
IPC: F03G7/04
Filed: 1981-05-15
Abstract: A method of generating energy comprises expanding a gaseous working fluid from a charged high pressure level to a spent low pressure level to release energy, and regenerating the spent working fluid. The working fluid is regenerated by, in at least one regeneration stage, condensing the working fluid in an absorption stage (A) by dissolving it in a solvent solution while cooling with a cooling medium, the solvent solution comprising a solvent having an initial working fluid concentration which is sufficientto provide a solvent solution boiling range suitable for absorption of the working fluid; increasing the pressure of the solvent solution containing the dissolved working fluid by means of a pump (P) and evaporating the working fluid being regenerated by heating in an evaporation stage (E); withdrawing the evaporated working fluid for re-expansion to release energy; and recycling the balance of the solvent solution remaining after evaporation of the working fluid, to constitute the solvent solution for the absorption stage of that regeneration stage.

Abstract: The electrical conductivity of metal surfaces, particularly steel surfaces of plates of electrostatic precipitators, may be regenerated by treating the surface with a regenerating agent in the form of a hyrogen halide such as hydrogen chloride. Hydrogen halide may be utilized in either liquid, gaseous or vaporous form. If so desired, an ammonium salt such as ammonium chloride may also be used to enhance the regenerative powers of the hydrogen halide. For example, the surface of steel may be treated with hydrogen chloride and ammonium chloride to enhance the formation of ferric oxide which possesses a greater electrical conductivity than does ferrous oxide.

Abstract: This invention relates to methods, apparatus and articles for systems comprising optical fibers, in particular for feeding an optical signal into an optical fiber (30) through the buffer thereof and for withdrawing an optical signal from an optical fiber (42) through the buffer thereof. Preferably this is achieved with the aid of an optical coupling means (28, 34) which contacts and conforms to the surface of the buffer at a bent portion of the fiber (30, 42). The coupling means (28, 34) can for example be a polysiloxane. In a preferred aspect, the invention provides an apparatus and method for axially aligning the ends of optical fibers (32, 40). The apparatus comprises means (10, 12) for holding two fibers (30, 42) so that the fiber ends (32, 40) are approximately abutting and axially aligned, adjacent means for passing an optical signal into one of the fibers (30) through the buffer thereof, and adjacent means for withdrawing that signal from the other fiber (42) through the buffer thereof. 
     At least one of the holding means (10, 12) is movable to maximize the withdrawn optical signal and thus to align the fibers (30, 42). Preferably the apparatus comprises means for joining the ends of the aligned fibers (32, 40). The invention also includes novel splices which can be made in this way and novel splicing aids for use in the method. Suitable apparatus is illustrated in the drawing.

Abstract: The anodes for the electrolytic production of zinc from acid aqueous solutions of sulphate comprise a skin portion formed by conventional anode metal, lead containing from 0.25 to 1.0% silver, and a stiffening reinforcing member of titanium or zirconium. The reduction in thickness of the anodes, which is made possible by the provision of the reinforcing member, results in a substantial saving in the amount of silver-bearing lead which is immobilized, and a substantial reduction in the unit weight of the anodes. The resistance of the lead to anodic corrosion in a sulphuric acid medium is maintained and the resistance to corrosion by passivation of the reinforcing member permits the reinforcing member to be accidentally exposed, without disadvantage. To produce the anodes, the reinforcing members are clad with lead at a temperature of more than 100 DEG  by rolling sheets of lead, by casting in a mould or by spraying on molten lead.

Abstract: L'organe structural comprend un tube de pression (20) qui peut soit posseder un cable (144) tendu entre ses extremites soit etre monte a l'interieur d'un organe exterieur (14). Le tube de pression est monte de maniere a pouvoir se deplacer axialement par rapport au cable (144) ou au tube exterieur (11). Lorsque le tube est mis sous pression, une partie de la force est absorbee par la tension tangentielle dans le tube, et une partie de la force est dirigee vers les extremites du tube de pression et vers le cable ou vers l'organe exterieur soit au moyen d'un agencement a piston soit autrement. Lorsque des charges de compression sont placees sur le systeme, celui-ci peut supporter une force jusqu'a concurrence de la pre-charge sans presenter de deformation d'Euler. Le systeme est utile dans la construction de pilier lent et mince et de poutres longues ou la rigidite est un facteur important. Le tube de pression n'est pas sujet a une deformation due a la compression puisque ses extremites sont libres de se deplacer axialement sans comprimer le tube. Le tube de pression peut etre enveloppe dans un materiau fibreux unidirectionnel presentant une resistance elevee a la traction de maniere a pouvoir supporter une tension tangentielle plus elevee.
