Patent FR-2244830-A1 (FR)
Title: Electrolytic refining of copper - with reduced and optimised power consump-tion
IPC: C25C1/12
Filed: 1973-09-21
Abstract: Electrolyte refining of Cu by the electrode in series technique is effected by continuously casting an endless strip of Cu, cutting the strip into pieces whose length gives a suitable surface area, and using the plates formed from the pieces as electrodes in series in an electrolyte soln. contained in a vessel whose interior surface is of an insulating synthetic polymer material which is held at >=54 degrees C and through which a d.c. current is passed to dissolve impure Cu in the soln. and deposit purified Cu on the electrodes. This reduces power consumption for prodn. of a given amount of refined Cu and avoids damage to the vat sides by the edges of the electrodes as they are introduced into the vessel.

Title: Two stroke engine using hydrogen and oxygen fuel - produces water vapour condensing to return piston
IPC: F02B43/10
Filed: 1974-05-27
Abstract: The engine operates on the two stroke cycle. The water vapour produced by the combustion of hydrogen is condensed in the cylinder to reduce the pressure. The engine has the same components as a standard engine namely cylinder, piston, crank, ignition coil and cooling system. Additionally the engine has a distributor ring rotating at ending speed; slide valves operated by an electromagnet and an ignition control mechanism. As the piston moves from top dead centre the charge is aspired and ignited. The piston is forced downwards and water vapour produced. The vapour is cooled by expansion and condenses, producing a reduced pressure in the cylinder to return the piston from bottom dead centre to top dead centre.

Title: Forming relief patterns on materials sensitive to radiation - by chemical reaction under action of electromagnetic or corpuscular radiation
Inventor: KOSTYSHIN MAXIM TIMOFEEVICH
IPC: G03F1/54
Filed: 1976-01-12
Abstract: Relief patterns on materials sensitive to electromagnetic and corpuscular radiation are produced by forming a metal layer on a substrate, followed by a layer of an inorganic material capable of chemically reacting with the metal layer with the formation of reaction products having different physical and chemical properties than the inorganic material and for metal. Image of a pattern is projected onto the coated surface and some parts of the coating and removed. This method is improved in that between the metal layer and the inorganic material layer on intermediate layer is introduced consisting of a material which is inert with respect to the metal and the inorganic material unless exposed to an electromagnetic or corpuscular radiation. The thickness of this intermediate layer is sufficient to prevent any reaction between the metal and the inorganic material in the absence of any activity radiation. After the projection of an image the unwanted parts of this intermediate layer are removed along with the unwanted parts of the other layers. The intermediate layer is pref. formed by contacting the metal surface with an atmos. contg. O2 and/or Fe, Cl2, Br2, I2, S, Se or Te. Alternatively, the intermediate layer can be formed by chemical deposition from a soln. or a melt. The removal of unwanted parts of the intermediate layer can be carried out mechanically or by chemical etching or by sublimation at an elevated temp. During the irradiation an electric field can be applied. Objects with a relief surface pattern can be produced, such as holograms, diffraction gratings, polarisers for electromagnetic waves, photo stencils, elements of microcircuits, printed circuit plates, information storage cells, typographic plates, etc. Electromagnetic or corpuscular radiation having a lower intensity than in the conventional process can be used; red and mean infrared light can be employed.
