Abstract: 1,229,887. Suspended roofing structures. GRANDI PADIGLIONI S.p.A. 19 June, 1968 [30 June, 1967], No. 29171/68. Heading E1W. A roofing structure comprises an outer rigid structure 11a supporting an outer ring structure 12a and an inner rigid structure 18 supporting an inner ring structure 16a substantially co-axial with the outer ring structure, a first system of cables 15a each of which extends as a chord between two points on the outer ring structure and a second system of cables 13a each of which extends from a point on the outer ring structure 12a to a point on the inner ring structure wherein one of the cable systems overlie the cables of the other system and serve as tensioning cables exerting a downwardly directed force on the cables of the other system, which latter serve a roofing supporting cables. In the embodiment of Fig. 6, for a circular building, the inner ring structure 16a is located above the level of the ring structure 12a, and it is the cables 13a which serve as roofing supporting cables, the cables 15a serving as tensioning cables. In an alternative form, for an annular building Figs. 1 to 4 (not shown), the inner ring structure is located below the level of the outer structure and the respective functions of the cable systems is likewise reversed.

In the manufacture of flat glass by the " float " process the tank structure is lined with an alumino-silicate refractory comprising 40 to 80% by weight alumina, and from 20 to 55% by weight silica and having evenly distributed pores of uniform size distribution linear over the range 0.02 to 100 Á. It is preferred that the refractory contains not more than 1% of alkali, expressed as oxide and less than 1%, preferably less than 0.5%, of iron oxide expressed as Fe 2 O 3 . As shown the lining 9-12 of the side and end walls extends above the surface of the level of molten metal. The refractory chosen does not exhibit undesirable glass forming properties with elements present in the molten metal bath, e.g. sodium which has entered from the glass. The porous refractory is advantageous when a negative pressure is applied to an interspace between the lining blocks 9-12 and the outer casing 5-8 of the tank.

Abstract: 1,265,339. Closing envelopes; applying labels. G. BILLI & C. S.p.A. 16 Sept., 1969 [19 Sept., 1968], No. 45574/69. Headings B8C and B8F. An apparatus for closing filled envelopes (1, Fig. 1) having closure flaps (5, Fig. 1) includes a plurality of carriages 24 mounted between a pair of endless chains 26, each carriage including an envelope supporting plate 24A having a rigid edge portion 78 pivoted about a hinge 80, a pressure-plate 84 biased by a spring 86 towards the plate 24A and an extension 94 and a lever 90 both operable to raise the pressure-plate 84 against the bias of the spring 86. In operation, each envelope is filled in a semi-automatic manner by two movable arms (20, Figs. 5 and 6) stretching the envelope mouth for the insertion of a sheet (9, Fig. 2). The filled envelopes then slide down an inclined grid 22 on to the plate 24A and when in the desired position activate a micro-switch (98, Fig. 8) which initiates the drive of the chains 26. When located correctly on the plate 24A, the upper edge of the sheet (9) and the fold-line of the flap (5) are aligned with the hinge 80. Upon movement of the carriage 24 the extension 94 is moved beyond a stop 96 and the envelope retained between the plates 24A and 84. Further intermittent movement of the carriage 24 causes the edge portion 78 to engage a guide track 104 which raises the edge portion 78 to a position whereat a toggle-spring 106 is able to effect further pivoting of the edge portion 78 and hence complete the folding of the envelope closure flap (5). Self-adhesive labels 12 are applied to the folded flaps (5) by movement of a tape 102 carrying the labels across the end of a blade 100. The edge portion 78 is then pivoted back to its initial position by engagement between a fixed guide track 108 and an extension (78A, Fig. 15) of the edge portion and the action of the toggle spring 106. When the carriage 24 approaches a sprocket 74 the front end of the lever 90 contacts the sprocket hub 74A causing the release of the labelled envelope 17.
