Title: Inorganic support for culture media
IPC: C12N5/071
Filed: 1975-11-11
Abstract: 1494534 Inorganic support for culture media WYO-BEN PRODUCTS Inc 11 Nov 1975 [22 Nov 1974] 46576/75 Heading C6F An aqueous microbial or tissue-cell culture medium consists essentially of a natural or artificial inorganic support e.g. clay, nutrient matter and water, and the support is water-swellable to an extent of at least three-fold in contact with sufficient water and, together with water, constitutes a solid or semi-solid non-particulate mass which is inorganic, is water-retentive, is thixotropic, and is a non-nutritive microbial or tissue-cell growth support. The inorganic, water-swellable support is exemplified by 200 mesh bentonite which has been refined by centrifugation to remove grit and non- colloids. Other preferred features are that the support is stable over the pH range 2 to 12 and constitutes 4 to 12 per cent (w/v) based on the volume of water in the medium, The (W/v) relationship between the inorganic support and the water which swells it to a solid or semi-solid mass is within the range 3:100 to 3:25. The culture medium is prepared by blending the water with sufficient of the water-adsorbing support to obtain a smooth thick slurry, admixing nutrient matter with the slurry, sterilizing the resulting mixture, and permitting the sterilized product to set to a solid or semi-solid mass. The Examples disclose culture media formulations suitable for the cultivation of specified bacteria, yeasts, fungi including moulds, and animal and vegetable tissue cells.

Title: Process for production nitrosyl chloride
IPC: C07F9/04
Filed: 1962-12-21
Abstract: Nitrosyl chloride is produced by reacting gaseous nitrogen dioxide with aqueous hydrochloric acid at a temperature between 20 DEG  C. and 70 DEG  C. Aqueous nitric acid is formed as by-product. The nitrogen dioxide may be employed in the form of a mixture with an inert gas, for example the gaseous combustion product of ammonia. Preferably the aqueous hydrochloric acid and gaseous nitrogen dioxide are led in countercurrent contact through a plurality of distinct reaction zones, the gaseous and liquid reaction products being separated from each other, the gaseous reaction products evolved in the last stage zone (referred to the flow of hydrochloric acid) being forwarded to the preceding zone via an oxidation zone where any nitric oxide is oxidized to nitrogen dioxide; recovering from the first-stage reaction zone the ultimate gaseous reaction product containing nitrosyl chloride, and from the last stage reaction zone aqueous nitric acid.  The reaction vessel may be a tray or packed type column, or a container with a bubbler at the bottom.

A method of straightening a laterally curved metal band while it is moving in its longitudinal direction, comprises plastically deforming the band across its entire width in successive steps at longitudinally spaced parts of the band so that the shorter longitudinal edge is lengthened to a greater extent than its longer edge. A metal band or strip is drawn off a reel 2, passed through and stretched between guide units 3, 4 each comprising a pair of rolls, one being spring biased towards the other and then on to a wind-up reel 5. The strip is also laterally guided by rollers 9 and the curvature measured by gauging rolls. A device 11 mounted between the units 3, 4 and reciprocable in the strip feed direction along a track on the machine bed 8 comprises a pair of press bars 12, 13 (Fig. 5, not shown) on which are mounted dies 14 of a circular cross-section. The bars are moved relatively towards one another by hydraulic means 15, 16 so as to plastically deform the strip passing therethrough, in an axial direction, by applying a transverse force across the strip to effect stretching of the concave edge thereof relative to the convex edge. The force distribution across the strip may be controlled by spacers 17, 18 and the unit actuated either automatically in conjunction with the gauging means 10 or manually. During the pressing operation the means 11 may be taken along with the moving strip and upon release retracted to its initial position by spring means.
