Abstract: 767,130. Load-handling machines. RUSSELL; BURDSALL & WARD BOLT & NUT CO. April 8,1954 [June 22, 1953], No. 10348/54. Classes 78 (3) and 78 (4). Coils 34, Fig. 1, to be engaged with a lifting spider 20 are first placed in a troughshaped cradle 11 which is then turned about a pivot 12 to place the coils with their axes vertical. The lifting spider 20 is then raised to the position indicated in broken lines in Fig. 1 by an elevator or by lowering the hook 36 of a crane through the stacked coils. The cradle is tipped by a hydraulic ram 23 pivoted at 129 to the cradle and at 53 to a substructure supported from a carriage 10 which carries the pivot 12 of the cradle and can be moved towards and from the centre of a well 18 by a hydraulic ram 84. The lifting spider 20 comprises circumferentially spaced pipes 24 secured to an apertured upper plate 28, Fig. 1, and to a lower plate 25 provided with an angular flange 26, Fig. 6, which takes beneath a flange 31 on a ring 30 by which the coils 34 are supported. The ring 30 is placed in the cradle 11 before the latter receives the coils 34 so that it supports the coils from an apertured end plate 106 and, when the cradle has been tilted and the lifting spider 20 raised, it supports the coils from the lower plate 25 of the spider. The spider 20 is raised from the pit 18 by a disc 143 removably carried on a ring 142 supported by brackets 141 from three screws 140 carried by screws 135 rotated simultaneously through a chain and sprocket drive. The elevator avoids the damage to the lifting tackle which would result from lowering it through the coils after their removal from a heat treatment furnace.

Title: Improvements in or relating to method of producing silica fibres and fibrous articles produced thereby
IPC: C08L61/10
Filed: 1947-04-24
Abstract: 636,893. Heat insulation. THOMPSON CO., H. I. April 24, 1947, No. 10970. Convention date, May 11, 1946. [Class 64(ii)] [Also in Group XXIII] Resin-bonded silica fibres in woven, batt, mat, cord or other fabricated form are produced by leaching resin-bonded glass fibres in the said fabricated form with acid for a time and at a temperature sufficient to leach out of the glass, the glassforming metallic oxides, but without leaching any substantial portion of the SiO 2 , the ratio of SiO 2  to glass-forming metallic oxides remaining in the fibres being more than 9 to 1. The leached fibres may be substantially dehydrated by firing, this treatment removing the resin which has served its purpose in giving mechanical strength to the leached fibres to withstand the washing and drying. The fibres in fabricated form are usable as heat-insulating materials at temperatures higher than those tolerated by glass-fibre insulation, the melting point being in excess of 1900F, or in some cases, in excess of 3000 F. Suitable bonding materials and acids are referred to (see Group XXIII), and examples of glass compositions, acid strengths and temperatures, and treatment times, and the resulting melting points and shrinkage in fibre dimensions are given. In some cases, preformed insulating structures of leached fibres are dehydrated, and the resin bond is removed by the in situ heat, the insulation being thus caused to shrink into its proper position. Provision is made for the release of vapours and gases during the heating to prevent the formation of blowholes. Specification 595,498, [Group XXIII], is referred to.
