The reaction-products improve tensile wet-strenght in paper manufacture.  Specified polysaccharides are starches, amylose, amylopectin, celluloses and gums.ALSO:The tensile wet strength of paper is improved by adding to the paper pulp, or treating paper with, an aqueous dispersion of a reaction product of 70-85 parts by weight of a dialdehyde polysaccharide with (1) 15-30 parts by weight of a dicyandiamide-formaldehyde condensation product or (2) 15-30 parts by weight of a hypochlorite oxidised polysaccharide; or (3) a mixture of 7.5-15 parts by weight of the condensation product and 7.5-15 parts by weight of the hypochlorite oxidised polysaccharide.  In Examples, such reaction products, based on p  starch, are added to bleached cellulosic Kraft pulp of 450 cc CSF and a consistency of 1.0 weight % based on oven-dry pulp, and handsheets are made therefrom.  In one Example, zirconium oxychloride is also added to the pulp as a cationising agent, although the products of use of a separate cationising agent with the polysaccharide reaction products of the invention is not essential.

Abstract: <PICT:1112083/C1/1> In the manufacture of cellular glass, a mixture 23 of powdered vitreous or glass-forming materials and a foaming agent is fed, as by a conveyer 24, at a controlled rate on to a static support 2 which is not wettable by molten glass or on to a ribbon (51) of glass advanced along the support at a controlled rate to form a layer 29 of substantially uniform thickness which is continuously advanced and heated sufficiently to cause the mixture to cohere and foam, as at 31, to form a ribbon 32 of cellular glass which is cooled as it is advanced. The support may, as shown, be a molten metal bath 1 but alternatives given are a carbon channel or a gaseous film.  As shown, reinforcing wire 42 may be introduced from a reel 40 over rollers 44 into the pass between the end roller 26 of conveyer 24 and a guide roller 30 which advances the layer 29 along the surface.  When the mixture 23 is fed on to a ribbon (51) of glass, advanced on a molten tin bath 1, the feed hopper (52) is mounted in the roof structure over the bath and an intermediate particulate layer of a decorative material, such as enamel frit, copper, copper and titanium, aluminium, ground quartz or mica, is introduced from a hopper (59) before the mixture 23. A number of suitable mixtures for the cellular glass and foaming agents are given, including loess or soda-lime-silica cullet with ferric oxide and carbon, sodium or calcium sulphate with carbon or calcium carbonate.  Carbon may be used on its own when the powdered glass contains, e.g. a sulphate, arsenate, antimonate, sulphite, thiosulphate or peroxide.  Colouring agents may be added, e.g. chromic oxide, cobalt oxide, calcium sulphide or ceramic pigments.

The rod 17 then anchors other slip sections assembled to the section 2a, these being moved along the track 3 by shortening or lengthening the chains or cables 19. When the ship sections have been assembled the trigger device 9 is installed beneath the bows and the rod 17 is removed. The device 9 (Fig. 4) comprises a trigger 30 which is held by a locking lever 32 in a position wherein it engages a cross pin 27 on a plate 20 welded to the bow section, the trigger 30 being mounted on a carriage 28 anchored by means of an hydraulic cylinder 36 to a girder 39 engaging stops 6k on the track 3.
