Abstract: 459,519. Making tubes; burners. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(Air Reduction Co., Inc. ; 60, West 42nd Street, New York, U.S.A.) July 8, 1935, No. 19492. [Classes 83 (ii) and 83 (iv)] [See also Group XI] Bending; drawing ; welding.-Skelp is heated in a furnace and is delivered to apparatus for forming it into a tube, such as a drawing- die, idler rolls acting as a die, or driven rolls for driving, forming, and welding the skelp, the edges of the strip being further heated by oxyacetylene or other flames during its passage to the forming means. Skelps 12, Fig. 2, are heated in a furnace 11, and are drawn through heating-devices 32 and the drawing-die 18 by tongs actuated from an electric motor driven chain 19. The drawing and heating apparatus pivot about the end 21, rollers 22 at the other end running on a track 23, to present the apparatus at different positions to the furnace 11. The heating-devices comprise burners 33, Fig. 5, at each side of the skelp, each burner having a number of jets so spaced that the edge of the work is subjected alternately to heating and deoxidation as it passes through the inner and outer zones of the successive jets. The surfaces are also kept free of oxide by unconsumed gas. Passages 72 for cooling are provided in the burners. The guides for the skelp comprise upper and lower members 43, 44, which may have grooves 60 in their guiding faces, spacing being determined by shims 48 also acting as lateral guides, and preferably being copper-plated for this purpose. The burner units, shims, &c. are adjustable transversely. Cooling passages 71 are formed in the guides 43, 44. In a modification, the upper guides 133, Fig. 10, may be moved clear of the skelp. Lateral guides 139 are secured by bolts 140 to the guides 133, and are moved by a lever 167 to clear a shoulder 157 on the lower guides 126, this movement being permitted by a slot 171 in which a pivot 166 bears, the guides 139, 133 then rocking about the pivot 166. A latch 160 is depressed on actuation of the lever 167, this latch normally engaging a recess 162 in the guide 139. The two sets of guides are interconnected to be operated together from one handle.

Filed: 1974-05-07
Abstract: 1441369 Light guides PLESSEY CO Ltd 11 March 1975 [7 May 1974] 19968/74 Heading G2J An optical fibre transmission compensator which transposed fast modes in a fibre fl into slow modes in a fibre f2, and slow modes in fl into fast in f2, comprises three focusing systems I, T1 to T3, and F, symmetrically located about an axis 33. The compensator acts as follows:- the lens I brings to a focus in a ring of radius gh the rays ma . . mc of a mode m, or to a point g in the case of a mode z propogating parallel to the axis 33, so that all modes are focused in concentric rings in a plane 5; an entrance lens N in the plane 5 transmits the rays in each mode emanating from the centre of the fibre f1 in a direction parallel to the axis 33; the lenses T1 ... T3 perform the required transposing, so that mode z which has zero angle in f1 has maximum angle at plane 6, and vice versa for mode M; and exit lens X is identical with the lens N, and a lens F is identical with the lens I. All the lenses have the same focal length, except T2 which is half the others. In a modification, see Figs. 4 and 5 (not shown) the lenses are replaced by three optic fibres (P, Q, R) the index of which varies with radius, in (P, R) decreasing as the radius increases, Fig. 5a, and in (Q) increasing as the radius increases to a point (c), Fig. Sb, then decreasing. (P) corresponds to I, N, (Q) to T1 ... T3, and (R) to X, F, and this embodiment allows (Q) to transpose the mode (8) of middle group velocity, rather than the mode m of middle angle.

The strip 16 is produced by depositing two continuous strips of adhesive, either in liquid form or as preformed strips, along the edges of a continuous length of foldable material from which the tray blanks (12) are cut or along the side edges of the blank (12) per se. The adhesive used is a thermoplastic adhesive such as polyethylene. To form a package (10, Figs. 4 and 7) of bales of rubber utilizing the tray 14, a tubular shroud (34, Figs. 4 and 7) of heat-shrinkable material, closed at its upper end, is placed over a stack of bales (8, Figs. 4 and 7) on the tray 14 to enclose the bales 8 and the side walls 24, 26 of the tray 14, the lower end of the shroud is bonded to the adhesive strip 16 and then the shroud is heated to shrink it into tight engagement with the bales of rubber. Air is able to escape or may be withdrawn by a vacuum pump from within the shroud (34) through channels 30 formed between the non- bonded portions of the side walls 24 and the shroud. The shroud may be a film of polyethylene, polypropylene or polyvinylchloride. The heat-shrinking of the shroud is effected by lowering a hot air heating ring (36, Fig. 5) around the package or by passing the package through a heating tunnel or by directing a hot air gun at the package. One side (38, Fig. 5) of the heating ring (36) is adjustable to accommodate rectangular packages of various sizes.
