Patent GB-961408-A (GB)
Title: Process and apparatus for the production of steel
IPC: C21C5/52
Filed: 1961-05-23
Abstract: <PICT:0961408/C6-C7/1> Steel is produced by feeding a partially reduced mixture of iron ore, carboniferous fuel such as coal, and flux e.g. lime pellets, in a heated condition into a first electro-furnace, smelting the mixture to produce a primary pig iron melt and an iron-rich slag, smelting the iron-rich slag produced with further carboniferous fuel such as coke in a second electro-furnace to produce a secondary pig iron melt, and refining both the pig iron melts in a refining furnace such as an electro- or a Siemens-Martin furnace. As shown, the initial mixture may be ignited by hot gas and air in a sintering device 1 to reduce to about 70% by weight of the original charge, and the partially reduced may be fed e.g. at 1200 DEG C. into the reaction chamber 4 of an electric furnace container 2, the iron-rich slag produced flowing over a water cooled ceramic dam 3 into the reaction chamber 5 for further reduction. Each chamber 4 and 5, forming the first and second electro-furnaces, may be provided with independently operated electrodes 6.  Both the pig iron melts are tapped via tap-holes 7 to be refined in another electro-furnace 8, the iron-poor slag being withdrawn through tap-hole 9.

Filed: 1944-10-07
Abstract: 606,956. Photographic roll-film cameras. LIVENS, W. H. Oct. 7, 1944, No. 19254. [Class 98 (i)] A photographic camera comprises two parts containing the film spool supporting means and adjustable relatively to each other and to the remainder of the camera and attached to masking means which expose different areas of film as desired. The camera comprises a central part 1 and two end parts 2, 2a, slidable thereon, carrying mountings for the spools. Two plates 5, 5a, overlap at 6 and have inwardly-directed walls 7, 7a which fit into recesses in the end walls 8, 8a, of the parts 2, 2a. The slidable members can assume three different positions determined by spring- biassed latch plates 13 engaging in notches 16. The film in the magazine is controlled during the frame-size adjustment, a spring-urged cable drum integral with the magazine and connected by a cable to the camera casing, causing the magazine to rotate and pay-out or take-up film according to the change in frame. A masked member with transparent openings of different sizes slides with the magazine movement across the view and rangefinders and controls the view appropriate to the frame size. Coloured parts at the side of the transparent opening may indicate the full frame field. The film is wound on automatically by means of a fly-back key and a clutch with extra manual control by a knob connected directly to the spool. An exposure counter and a shutter locking connection are provided. The selection of frame size also controls the film feed, a rack 121 secured to the central body part engaging a pinion 124 which carries a stop 125, Fig. 15, and adjusts its position. A pin 118b on the winding pinion 118 contacts this stop to limit the winding stroke. The amount of flyback is also limited by a further pin 118a, which is engaged by the inclined end 117a of a compensator plate 117. The position of the end 117a is subject to two adjustments of the plate 117, one depending on the amounts of film fed being determined by a feeler on the spool to increase the winding stroke as the amount of film on the spool decreases and the other determined by the size of the frame by controlling a pin 122 on the rack 121 which engages a slot 126 in the compensator plate 117. The camera has an annular focussing ring and lens hood and in the collapsed position the lens, shutter and hood are nested in a draw-tube.
