Abstract: Wet-laid paper having, when creped, improved bulk, softness, and flexibility; a relatively large cross-machine-direction to machine-direction stretch ratio; and improved burst to total tensile stremgth ratio. The paper is characterized by an array of uncompressed zones (42) which are in staggered relation in both the machine direction and the cross-machine direction; and by having each uncompressed zone defined by a picket-lik discontinuous lineament of compacted fibrous material (43). The invention also includes a process for making the paper through the use of an imprinting fabric which is configured to precipitate the requisite compacting of the picket-like lineaments prior to final drying and creping of the paper.

Abstract: A process for the production of a xanthan gum depolymerising enzyme (hereinafter termed «xanthanase») which comprises culturing Corynebacterium strain 20/122 (deposited with NCIB under accession number 11535) under aerobic conditions in a liquid growth medium comprising assimilable sources of nitrogen and essential mineral salts and, as the sole carbon source, xanthan gum, separating the bacterial cells from the reaction mass and recovering the xanthanase from the resultant spent growth medium. 
     Also the xanthanase enzyme produced by the foregoing process, which enzyme has been characterised by the reaction products derived from the enzymic depolymerisation of deacetylated xanthan gum. There are 4 major products, which have Rf values of 0.55, 0.50, 014 and 0.05 when resolved by chromatography on cellulose thin layer plates using, as solvent, ethyl acetate-pyridine-glacial acetic acid-water (5 : 5 : 1 : 3 by volume), and detected with standard silver nitrate-sodium hydroxide spray reagent. The four were further identified by sugar analysis as being, in order of decreasing Rf value, mannose, mannose ketal-linked to pyruvate, an oligosaccharide containing glucose, mannose and uronic acid in the proportions 1.0 : 0.5 : 0.34 respectively, and an oligosaccharide containing glucose, mannose and uronic acid in the proportions 1.0 : 0.84 : 0.55. 
     Also a process for the depolymerisation of xanthan gum or carboxymethyl cellulose (CMC), in which an aqueous solution of the gum or CMC is reacted with the <anthanase produced as defined above at a temperature between 25°C and 70°C, preferably 30°C, and a pH between 5 and 7, preferably pH 5.6.

IPC: B22C9/04

Abstract: A method of casting a metal article in a mould box comprises locating an expendable pattern in the box, the pattern having a gas permeable refractory coating thereon, placing and compacting unbonded particulate material about the pattern and supplying molten metal into the box so as to vaporise or burn away the pattern and form the article of defined shape while applying a vacuum during casting. According to this invention, the method is improved by compacting the particulate material to a maximum bulk density where it contacts the coated pattern and applying a vacuum to the compacted particulate material so as to create sufficient pressure gradient in the height of the compacted material to maintain the integrity of the gas permeable refractory coating. in this way, the risk of mould collapse, metal breakout, and pollution are reduced.

Abstract: Evacuation de sulfure d'hydrogene present dans des gaz. Un probleme, commun aux systemes regenerateurs et aux procedes aux copeaux de bois, reside dans le fait que l'on ne peut se debarasser des produits de reaction sans polluer l'environnement. Par contre, lorsque l'on utilise le present procede, les produits de reaction sont stables et l'on peut s'en debarrasser en toute securite. Ce procede utilise une suspension liquide de particules d'oxyde de fer uniques consistant essentiellement en Fe2O3 amorphe et en Fe2O3 cristallin, Se3O4 et leurs combinaisons et ayant une surface specifique d'au moins 4m2g. Lorsque on fait barboter dans le liquide le gaz contamine par du sulfure d'hydrogene il est en contact intime avec les particules en suspension, et les produits de reaction d'activite stable sont formes. L'invention est specialement utile pour l'adoucissement du gaz naturel au niveau de la tete du puits en utilisant des cuves de reaction relativement simples, de faible cout, et d'un entretien impliquant des temps d'arret minimum.
