Title: Method and device for plasma-arc remelting the surface layer of a plane metallic workpiece with parallel edges
IPC: B23K10/00
Filed: 1980-02-27
Abstract: The method provides for placing a plane workpiece (1) in its initial position horizontally between cooled beams (2 and 3) of a crystallizer. Plasma-arc burners (6) are placed in a row above the workpiece (1) and across its parallel edges (1a and 1b) so that the anode spots of the extreme burners (6a and 6b) are limited by the edges of the workpiece (1). A plasma-arc generating gas and electric current are fed to the plasma-arc burners (6), the workpiece thus being heated and a bath (8) of molten metal being produced on it, its length being equal to the distance between the edges (1a and 1b) of the workpiece (1). The workpiece (1) and the plasma-arc burners (6) being moved in relation to each other in a horizontal plane and along the edges (1a and 1b) of the workpiece (1), the displacement of the bath (8) of the molten metal is thus ensured along the surface of the workpiece (1). As a result a remelted surface layer is obtained on the workpiece its thickness being equal to the depth of the bath (8). A device implementing this method comprises a pressurized chamber (11) and a crystallizer mounted therein and including two beams (2 and 3) which are oriented in a horizontal plane and are parallel to each other. Plasma-arc burners (6) connected through supply lines (12, 13, 14) to sources of a plasma-arc generating gas, of electric current and cooling water are mounted inside the chamber (11) on shafts (17). Each of the shafts (17) is mounted by means of a seal bushing (18) in the wall of the chamber (11) so that its axis is parallel to the beams (2, 3) and is provided with a drive (24) for its own axial rotation. The device is further provided with a drive for reciprocal displacement of the workpiece (1) and the shafts (17) in a plane parallel to the beams (2, 3), that drive being connected with at least one of the elements participating in the said displacement.

Title: Improvements in or relating to the production of cellulose derivative or cellulose conversion product compositions
IPC: C08B11/20
Filed: 1938-06-21
Abstract: 516,144. Cellulose derivative compositions. HOUGHTON, A. A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 21, 1938, No. 18466. [Class 2 (ii)] Cellulose derivative or conversion product compositions containing suspended solid effect materials are obtained by subjecting the insoluble effect material to mechanical treatment under non-alkaline conditions and in contact with a water-wet undissolved cellulose derivative or conversion product which is insoluble in water but capable of being brought into solution in an aqueous caustic alkali solution. The cellulose derivative may be one which can be dissolved in aqueous alkali at ordinary or reduced temperatures by simple mixing, or by subjecting a mixture of the cellulose derivative' with dilute aqueous alkali to freezing and then allowing the mixture to thaw, or by cooling such a mixture in presence of a dispersing agent or another colloid, or by using a colloid mill. After the effect material has been sufficiently dispersed, the resulting mixture, in presence of sufficient caustic alkali and water to ensure solution of the cellulose derivative or conversion product, is subjected to a treatment to bring the cellulose compound into solution. The cellulose derivative or conversion product may be a methyl or ethyl cellulose, a glycol cellulose, cellulose glycollic acid, cellulose sulphate, or a regenerated cellulose provided that it has the desired solubility. Pigments, pigment-lakes, fillers, e.g., talc, clay, barytes, graphite, or carbon black, or metal flake powder, natural or synthetic waxes, e.g., carnauba wax, chlorinated naphthalene or diphenyl compounds, cetyl alcohol, or paraffin wax, or fibrous fillers such as cotton or fibrous ethyl or benzyl cellulose, may be used for the effect material. Waxes or other easily-fusible solids may be mixed initially in the molten state, the mixing being subsequently continued at a temperature below the melting point of the solid. Dispersing agents may be present. Glycol cellulose is mixed with carbon black in presence'of water. The mixture is then cooled with ice, and caustic soda solution and a dispersing agent are added. When the glycol cellulose has dissolved, the temperature. is allowed to rise. The product may be used as a printing paste..Other examples describe the production of methyl cellulose or glycol cellulose compositions containing dye pigments, titanium dioxide, china clay, or paraffin wax. The compositions are used for printing textiles, delustring artificial silk, for padding on to cloth, or for loading textile fabrics, or for modifying the handle of textiles. After application of the compositions they may be fixed by coagulation by means of dilute sulphuric acid, acetic acid, or ammonium chloride: Specifications 410,152, 410,153, and 445,571 are referred to.

Title: Single-mode optical fibre telecommunication apparatus
Inventor: HASEGAWA AKIRA
IPC: H04B10/00
Filed: 1983-02-21
Abstract: Pulses of electromagnetic energy of appropriate peak power can form soliton pulses in monomode fibre (12). The width of such pulses changes during propagation, and can decrease for certain ranges of peak power, e.g. between about Po and 9/4Po, where Po is the "balanced" peak power. Using this property, repeaterless transmission of soliton pulses is possible if the pulses are amplified in non-electronic amplifiers (13) (meaning amplifiers in which the optical pulses keep the form of optical pulses throughout the amplification process) by appropriate amounts at appropriate intervals. Exemplary amplifiers are glass laser, Raman laser, semiconductor laser medium. and cw injection. <IMAGE>

Title: Solid state image sensors for rangefinders
Inventor: LAMBETH DAVID NOEL
IPC: G01S7/4914
Filed: 1983-08-18
Abstract: A rangefinder device includes means for projecting a beam of light to illuminate a spot on an object in a scene, an image sensor having an array of photosensors for sensing an image of the scene, and signal processing means responsive to the photosignals from the photosensors for determining the relative location of the illuminated spot in the scene. The device includes an improved image sensor comprising an array of N photosensors for sensing the image of the scene and generating N photosignals in response thereto, and an analog shift register having 2N cells for receiving the photosignals, in parallel, into N alternate cells. The sensor is operated once with the light beam off and the photosignals generated thereby, representing the background illumination, are entered into the N alternate cells of the shift register. Then the contents of the shift register are shifted by one cell. Next, the sensor is operated with the beam on and the N photosignals, representing the background plus the light beam illumination, are entered into the shift register, with the result that the background signals are interlaced with the background plus light beam signals in the shift register. The photosignals are read out of the shift register serially, and the pairs of signals originating from each respective photosensor are differenced to yield a series of N photosignals free from background scene information. The difference signals are supplied serially to a peak detector to determine the location of the illuminated spot.
