Title: Improvements in and relating to the manufacture of girders
IPC: E04G21/12
Filed: 1969-08-15
Abstract: 1285046 Making girders; tensioning PROCEDES NOUVEAUX DE CONSTRUCTION "PREFLEX" SA 15 Aug 1969 [19 Aug 1968] 40810/69 Headings B3A and B3E [Also in Division E1] In a method of making a pair of bent girders comprising simultaneously bending in a vertical plane the webs 1, 2 of the girders and embedding their tensioned flanges in concrete, the flange of the lower girder is first embedded in concrete 5 and when the concrete has set the pair of girders is pivoted through 180 degrees about a longitudinal axis and the tension flange of the other girder is embedded in concrete. The innermost flanges of the pair of girders are placed on either side of ribs 11 of supports 7 and rest on cross pieces 14, 15. The girders are bent by rotating screws 16, which abut the ribs 11 and pass through threaded bosses 17, 18. The concrete mass 5 is held by an adjustable locking element 26 and a bearing piece 49 of rib 10. The girders are pivoted by rotating threaded shafts 31, 37 to drive a nut 30 and connecting rod 29 upwardly thereby pivoting the rib 10 to a horizontal position. Simultaneously a nut 36 drives a connecting rod 35 upwardly to engage the rib 10 in its horizontal position. The shafts 31, 37 are then rotated in the opposite direction for the connecting rod 35 to complete pivoting of the girders. In an alternative construction, Fig. 8 (not shown), a single threaded shaft (48) is rotated to move a nut (47) and rod (46) downwardly to pivot the rib 10 into a horizontal position about a pivot (44) in a bearing (42). Upward movement of the nut and rod completes the inversion of the girders by pivoting the rib about a pivot (45) in a bearing (43).

Title: Sinter grate carriage
IPC: F27B21/06
Filed: 1958-12-23
Abstract: 846,064. Sintering grates. METALLGESELLSCHAFT A.G. Dec. 23, 1958 [Jan. 2, 1958; Feb. 1, 1958], No. 41518/58. Class 82(1) A sinter grate carriage has inserts 6 (Fig. 2), between the grate bars 5 and their supporting beams 4b, by which means direct conduction of heat from the former to the latter is considerably reduced. This permits the temperature of the sinter bed to be increased by 70‹ to 100‹C. above that previously possible with a given beam material. The greatest reduction in heat transfer is achieved by using ceramic inserts, but appreciable benefit can be obtained from inserts of a metal not having too high a thermal conductivity. Decreasing the effective contact area between the inserts and the grate bars and supporting beams respectively, by arranging for the former to have roughened, ridged or similar surfaces, results in further reduction in heat transfer.

In a lamp having an elongated tubular envelope with a coiled coil filament extending longitudinally with the ends connected to leadin conductors sealed through opposite ends of the envelope, the filament is in two sections joined and supported by two helical wire portions of a coil diameter and pitch corresponding to those of the secondary coiling of the filament, which extend into the primary coil of the adjacent filament section and which are supported from the inner wall of the envelope by a further wire portion. The latter may be in the form of a loop engaging the wall of the envelope over at least half the periphery. The loop may be combined with or terminate in a leg sealed into the envelope wall e.g. at the exhaust tip. Alternatively, a leg only may be used. The helical support portions may be at the ends of a single wave. Alternatively, the ends of the support portions remote from the filament and the inner end of the supporting wire may be formed as helices of such relative sizes that they can be screwed into one another in overlapping relation.

The tool slides 230 are mounted for radial displacement in guideways in a vertical plane and one angularly spaced about a workpiece guide bush 500. Each pair of radially opposed slides 230A, 230C and 230B, 230D are actuatable by a slide plate 220A, 220B respectively by way of a pin connection means. The slider plates 220A and 220B are driven from a single motor 212 or by an independent motor for each slider plate, the motor being mounted on the frame 200 and the drive to the sliders being provided through bevel gear units and feed screws 217A, 217B. In the embodiment in which only one motor is used the drive to the second bevel gear unit 210A, 210B, is provided by belt and pulley means 250. In order to enable selection of an appropriate cutting tool for operation the slider plates have secured thereto, tool selecting cylinders 240A-240D, to which hydraulic pressure fluid is admitted. The tool slides 230 normally occupy an inoperative position and are biased radially outwardly by springs 234 and when it is required to advance a slide 230 towards the bar stock 1 to be machined, oil pressure is applied to the respective cylinder so that the piston advances to engage an appropriate braeket 235 so that the bracket will be moved with the feed movement of the slider plate. The operative tool is thus held in engagement with slider plate whilst the inoperative tool remains in its retracted position. An additional tool slide may be actuated from one of the slider plates by way of a pivotable lever 260 which transfers the movement of the slider plate 220B to the tool slide 220C. The control of the operation of the tool slides is effected by numerical control or by tapes, the whole sequence of operation being effected automatically for a predetermined work cycle. The cutting tools 360 are each mounted in a holder 300 and are respectively securable to the tool slides by way of pins 336A, 336B, the holders being provided with various screw adjustments which are preset when the holder is set up on a jig so as to ensure the tool position set for any appropriate machining cycle. A jig with an optical setting device 430 is also described and which is provided with two setting stations 411, 421 in which the cutting tool with its holder is preset radially and axially respectively relative to an optical axis which corresponds to the axis of the workpiece when the tool holders are mounted on the frame 200. Each preset tool is subsequently mounted without further adjustment on the frame 200.
