  • Patent number: 4421850
    Abstract: An immobilized enzyme product is produced by contacting an inert particulate support with an aqueous enzyme solution containing preferably at least 25% dissolved solids and with a water miscible organic solvent, and crosslinking the enzyme to insolubilize the enzyme on the support as a gel containing 50-90% water. The water miscible organic solvent is in substantial excess of the amount of water mixed with the support in the process. The solvent may be contacted with the support before or after contacting with the enzyme solution. The resultant immobilized enzyme product has a bulk volume 5 to 300% greater than the bulk volume of the support material. A least a portion of the gel is external to the support and constitutes at least 3% by volume of the immobilized enzyme product.

  • Patent number: 4378089
    Abstract: Surface irrigation apparatus comprises a carriage movable along an irrigation canal. A dam is supported by the carriage in such a way that water flowing along the canal is incident upon the dam and is checked thereby and the carriage is pushed along the canal in the direction of flow. The carriage is provided with means for arresting its movement at desired positions along the canal. Preferably, the arresting means comprises on the carriage one or more arms which are releaseably engageable with stops on the canal although the arresting means could take the form of one or more brakes operated in accordance with the position of the carriage. The carriage also has means, such as syphon tubes, for transferring water from the canal to land to be irrigated.

  • Patent number: 4342603
    Abstract: A product comprising a mixture of .alpha.- and .beta.- forms of glucose as microcrystals, at least 70% of the glucose being in the form of the .beta.-isomer, dissolves readily in water to give approximately 60% solids solutions at ambient temperature. It is obtained by a process comprising the steps of(1) evaporating water from syrup at a pressure of less than 400 mm Hg to provide an at least 60% supersaturated solution of greater than 95% solids at a temperature of from 95.degree. to 140.degree. C.;(2) subjecting the supersaturated solution substantially instantaneously to a shear force to cause immediate nucleation of the syrup without cooling; and(3) immediately forming the nucleated but substantially uncrystallized syrup into a quiescent layer and allowing the layer to crystallize substantially isothermally to produce solid crystalline glucose.

  • Patent number: 4234688
    Abstract: The solution viscosity of a polysaccharide, microbial alginate, produced by culturing strains of Azotobacter vinelandii, is controlled by addition of a protease to the culture broth. The protease can be added during the culture, to obtain a polysaccharide of increased viscosity. Alternatively or additionally protease can also be added after culture but before the polysaccharide is isolated from the broth, for example, to prevent reduction of viscosity during storage. Neutral and alkaline proteases having activity at around pH 7 are particularly suitable.

  • Patent number: 4203268
    Abstract: A structural member comprising a sheet of industrial material in which is formed a plurality of dome-like projections of which at least the major portion of the configuration thereof in plan view is circular and said projections being located in the plane of said sheet in a structurally strategic geometric pattern which repeatedly blocks straight lines of vision across said sheet through said pattern of projections in all directions to form a one-piece rigid structural member capable of resistance to flexure and the intermediate portion of the sheet between said projections comprising arcuate continuous structural stress-resisting sections extending between the opposite edges of said member. Variations in patterns of projections comprise different embodiments of said member and, when fabricated, said member lends itself to a variety of end uses. When in the form of a composite panel, a flat sheet of planar material is affixed to the upper ends of said projections.
