Abstract: A machine for forming line pipe is disclosed wherein small diameter roll elements (11,12,13) not exceeding five times the thickness of the blank form a tube. The roll elements (11-13 positioned in a pyramid roll assembly are dynamically adjustable toward and away from each other to provide different size line pipe, or similar tubular articles. The segments of the roll elements (12) are mounted on cantilever arms (45), the leading edge of blank being deflected against the upper curved surface of the arms (45) during the final stages of forming. The deflection is maintained within the elastic recovery limit of the metal. A rigid frame mounts the cantilever arm (45) and other components. The frame includes a plurality of vertical bed plates (20) and corresponding upper frame plates (30) and cross tie members (31). A pusher mechanism pushes the sheet blank through the pyramid roll assembly. A multiwalled tube may be formed by providing the required additional length to the blank and continuation of the forming beyond 360°. The blank is confined between idler rollers (47a-47e) on the frame structures during forming. Special roller handling assemblies are provided for loading the blank and for unloading the finished tube from the machine.

Abstract: The invention relates to a discharge lamp which has a discharge vessel (1) provided with an external auxiliary electrode (11). The lamp also has a bimetal (14) which in the inoperative condition of the lamp causes the external auxiliary electrode to bear against the discharge vessel. 
     According to the invention the auxiliary electrode is connected to an end (14a) of only one bimetallic strip and in the operating condition of the lamp the auxiliary electrode is remote for the greater part from the discharge vessel due to the action of said one bimetal. As a result of this it is achieved in a simple manner that an auxiliary electrode stimulating the ignition is combined with an operating condition of the lamp in which no hindrance is experienced from the auxiliary electrode.

Abstract: Slag deposited on the bottom of a steel making furnace, especially a soaking pit for steel ingots, is difficult to remove. To enable this to be done while the furnace is hot, it is now proposed to supply a substance, e.g. ferro-silicon, which lowers the melting point of the slag, and a substance which reacts exothermically to initiate melting of the slag. When the slag is sufficiently liquefied, it is removed by means of a mechanical grab.

Abstract: Optical scanning apparatus for scanning a light beam (2) across a photosensitive surface (12). The scanner (6) is of the rotating polygon type, and has a positive cylinder mirror (10) located between the polygon scanner (6) and the photosensitive surface (12). The positive cylinder mirror, which has power in the sagittal (cross-scan) plane but no power in the tangential (scan) plane, minimizes scan-to-scan spot position errors due to angular alignment errors between adjacent facets (4) of the polygon scanner without introducing significant sagittal field curvature. Residual sagittal field curvature is compensated for by providing a negative refractive cylinder lens (14), with power in the sagittal plane, between the cylindrical mirror (10) and the polygon scanner (6).
